Who makes the best rebuilt motor?
 
Yeah I know. It's been up before but not when I needed a motor. THe warrentee company is balking at the job and I may have to foot the bill. IN that case screw the mazda reman.

Who makes the best motor for the price KD? RSR? Ivan? M2?

What did you pay for your rebuilt?

What about silcone orings? After market Apex seals?

Who does the best street port?

Mostly intested in the first two questions. THe rest is gravy.

TIA

I was just at Rotary Power in Gardena, CA (310-516-9959). They specialize in rebuilding rotaries and have been doing it since the early 80's. It's a small shop, but they really know their stuff.... the guy that owns it also runs a machine shop and does all the machining for the rebuilds himself - he's really good at it (I was told he has made the cams for the Cosworth indy car engines at the same shop). People have come from all over the US to get their engines built by him... Ari from Rotary Performance (rx7.com) recommends this shop for rebuilds.

They do 3mm apex seals, porting, turbos, you name it... prices are dependant on what you want done. He gave me the impressiong that it's anywhere from $2K on up.... he's built 1000hp racing motors, and he's done simple rebuilds with all stock parts - so prices can really vary.

Check out Hayes.

Has a 1st gen that does 9s no NOS and a supercharger.

Puts them in airplanes, you name it and prices are low.

NEVER get a Hayes Youll get what you paid for allright:eek:
im with RPNW.org we have more than a dozon complaints
about his motors.I will say that some of them were replaced
but it should be done right the first time!

Go to Pineapple Racing he also has a better warrenty & it will be done right the first time not 2,3,4th try....

www.PineappleRacing.com Rob is your contact.

NO less than perfection..



jimlab 08-07-01 05:42 PM

I second that... NEVER go to Hayes. They built two 3mm ceramic apex seal all-out motors at the same time, one for me and one for another customer. The other one was run first and grenaded before 500 miles. After Hayes failed to admit guilt and then failed to resolve the problem, Tri-Point disassembled the motor and said that the porting was the worst they'd seen and that the plates were junk. The rotors used were not '93-'95 rotors machined for 3mm seals, but instead '85 (?) rotors which originally came with 3mm seals... unfortunately the rotors need to be machined for the seals that are being installed, and they bound up, cracking two of the six, one in each rotor.

Based on these findings, we pulled apart my motor and found shoddy and incomplete porting (was charged for stage III street port and received less than half of what was promised), unmachined rotors (not my original rotors), plates that had been lapped so many times that the silicone O-rings that Hayes is so proud of had no place to go when the engine was torqued down, and split out the side. It would have overheated almost instantly if run, and they offer no warranty on their "race" motors, for all intents and purposes.

They agreed to fix the motor for the new owner (I had since sold it, having changed my mind and was going for a 20B at that time) if no one found out. Unfortunately he was a good friend of mine and I found out immediately, but kept quiet until they'd done the work. They would not let him inspect the motor in progress and kicked him out of the shop.

Dennis is the one who screws up the porting, and his son Don is the one who lies to you over the counter.

STAY AWAY FROM HAYES if you value your car at all. (3rd gen. specific... they seem to do "OK" with 1st and 2nd gen. NA motors, as far as I can tell... maybe they should stick to what they know)

[Edit] Forgot to mention. I gave them a ~5,000 mile 1995 motor with one bad housing and one bad rotor and they pocketed it and gave me ALL used parts in exchange. The other customer bought new housings and new rotors through Mazdacomp and they apparently pocketed those too, because his engine was also made entirely of used parts, from what I've heard.

Did I mention you should stay away from Hayes? :)

CantGoStraight 08-07-01 05:42 PM

I'm looking for a motor too so any information will be helpful.;)

WhtRocket 08-07-01 06:50 PM

Ok a good start.

In Summary:
Hayes -SUCKS
Pineapple - Very good.

Anybody want ot comment about KD?

I thought Hayes are the guys who make these cool apex seals. Are they the same company?



mpetersrx7 08-07-01 08:00 PM

Being from Palo Alto, I would think you would consider Rick's Rotary Perf, M2 and SR since they are all close. You could pop in and inspect the work.

I have heard good things about SR and Rick's before. Not heard either way on M2.

I am also interested in this topic since I know its only a matter of time.

GoodfellaFD3S 08-07-01 08:13 PM

Dave at KD is the man. Witness my recent dyno run w/the mods below, 12# boost, and NGK 11 Leading plugs. 321.4 peak rwhp and 256.0 peak rwt (dyno sheets up soon). I attribute most of that to Dave's port work. I live in TX and shipped to Dave; being in CA isn't a big deal. If you'd like to know more, PM me your phone #, ot PM asking me for mine. I'd be happy to tell you all about KD Rotary :).

take it easy guys...


kwikrx7 08-07-01 11:17 PM

I'll vouch for Dave at KD Rotary. He knows the 3rd gen like no other. he knows these engines. I've never met anyone who will let you watch him work on your car and teach you along the way. He explains everything and have heard nothing but great from EVERYONE that has been there. As for street-porting, Kim does most of the work and knows what she is doing. ErnieT just got a streetport from him - has the same mods as me (about) and just ran a 12.1 at 12 lbs of boost on non-seq. His engines put out great numbers and I can definitely vouch for his knowledge and would recommend him to anyone.

FindYourInnerSeven 08-07-01 11:25 PM

I've had my motor ported/rebuilt by Jeff McCall at Rotary Power also. He was quite friendly and eager to answer all of my many questions. I believe Abel Ibarra and Adam Saruwatari both had their motors done at Rotary Power also (can anyone confirm this? I remember reading this a while back in Turbo Magazine).

I've been running on Jeff's motor for 3 years now, and no problems as of yet.

Just my 2 cents.

FindYourInnerSeven 08-07-01 11:35 PM

I'm also near Rick's Rotary in the Bay Area..a talked to an acquaintance who got his engine ported there...said he paid close to 7000 dollars (holy shit!)...I'm sure Rick's know what their doing, but if this is indeed the real price, what a rip.

You betcha. Mine is done from there. The porting is awesome. It feels about as strong at 7psi as it did before the porting at 12psi. Not only that, low end power is improved, and milage is improved too. I've never gotten over 350 highway miles from this car, and right now I'm at 376 miles, with over 5 gallons left. They do awesome work.

ek9220ps 08-08-01 03:46 AM

I got my motor rebuilt at Rotary Power in Gardena, CA. I put 25,000 hard hi reving miles on and had a radiator and a water pump go out on it. Still running good.

RotaryiPAQ 08-08-01 12:51 PM

I highly recommend Pettit. They rebuilt my 93 Touring with 104K miles in April of 2000. Now, 16 months later I have 131K miles and it is just like the day I picked it up from them. They did the street port with 3mm seals. While I was there they were shipping motors out so if you're not near Fort Lauderdale you'd have to ship it or do like me, trailer it to them. I live near Atlanta and would still go there (600 + miles) to get anything serious done.

badass7 08-08-01 01:51 PM

OK guys, I have a Hayes Street Port that was done 3 years ago. I have a friend down here who has a Hayes engine and refered me to Hayes at the time. I did plenty of research before deciding to go with Hayes for my rebuild. There was no KD Rotary at the time and Pettit was way overpriced for me at the time as well. Unfortunately, I was not on this Forum..(if it existed) and did not hear all the bad things about Hayes until my engine was already being worked on. Talk about shitting on myself hehe!! Anyway, I must have called Don about 5 times and told him about that I had been told to stay away from them for specific reasons. HOPEFULLY, he took into consideration that I was aware of some of the shit they do around there and took his time on my engine. I even told Don myself to make sure that my engine comes out OK. Not sure what good that did. Well, after having it installed FINALLY (ya know what I'm talkin about JACK C. ;) ) I LITERALLY broke it in for a little over 3k miles!! No shit guys!!.....after hearing all of the horror stories and reading somewhere on an australian rotary website that a rotary engine isn't fully broken in until around 5k miles (something w/ an oil sealing issue??) I took my time and slowly broke it in! I didn't hit 7 psi. of boost and 7k RPM's until I was right at 3k miles. Then I had boost issues which I didn't address for another 500 miles which still kept me in the "Break in" mode. So, after 3500 miles and near 3 and a half months of driving I finally let it loose!! No, not a load...my engine :) .
Which now brings me to My Hayes street port. I have near 17k miles on it now and it absolutely runs Perfect!! I am getting a good (-) 19-20 psi. of vacuum with a smooth idle. Power is extremely noticeable in upper RPM's due to porting. Absolutely no excessive smoking or oil consumption. BUT, even with everything running fine....I am still wondering what the hell is inside my engine. After hearing all of the horror stories, I am wondering if my engine is just a Hayes Rotary ticking time bomb or if my numerous phone calls to Don just before they began building my engine really paid off?? I did ask Don at the time...."IF my engine were to go out" what would be the mileage or time frame. He responded that if a Rotary engine is to fail due to poor assembly or what not....it would happen within the first 500-1500 miles!! Well, I am way past that. Also, I have posted this question of Hayes reliability numerous times on the List and here on the forum and there actually ARE Hayes engines that are lasting well beyond 80k miles!! Who knows..... I guess time will tell. If this engine does go out again I will definitely go with RP or KD rotary.

I'd go Rotary Power myself. Jeff may be one of the most skilled people out there when it comes to rotory motors. His engines are ledgendary. Your in Cali, give them a call. You won't be sorry.

Part of me is hopeing my MazdaReman snaps sooner than later (under waranty), so Jeff can build me a true work of art to take its place.

ivan is the only one who actually puts all the nuts and bolts back in their original holes. he also will not spray paint garbage and sell it for a motor, like well mazda and some others. rick is ok, he does better on the early stuff. call ivan hes the only one who has worked on the 3rd gen nonstop since it came out around here.

Johnny 08-08-01 11:48 PM

Visit Rick's rotary in pleasanton...he know plenty about the 3gen...not only they early stuff..as for $7K ..I dont think so..but you can always ask. He wont BS you either...I've watched him do plenty of work and he explains everything...Donovan recently had his motor done by rick...ask him about it.

Rotary Reliability and Racing
 
Nick at Rotary does a great job.

I had mine rebuilt there about a year and a half ago. He did my streetport and takes care of my rx when I cant do it myself.

THOSE BOYS OVER THERE KNOW WHAT THEY ARE DOING....and they are affordable in comparison to tripoint...I think I paid 5300.00 for my motor and all labor as well as the streetport and some other small stuff back when I did it. TRI Point wanted 7500.00 just to replace the O rings. They wanted more than that to do the apex seals etc...

Nick has been working on rotaries for something like 20 years...he holds a lot of records for speed with rotary cars as well. Call him if you need a motor...you will see what Im talking about.

I put in the good words as they have taken such good care of me and my rx. My car would not be on the road if it werent for them...nor would it be as fast as it is.

The computer was screwing up and wouldn't boost 15....I also do all the upgrades (oil, coolant seals, ecentric shaft etc) I charge 2000-2200 (assuming your core is good).....That includes all new seals, springs, gaskets etc...)

He's been the local guru in Tampa for quite a while.

My 93 VR Base was rebuilt @ 112k

Cost: Engine w/3mm apex seals......$3,500
Turbos rebuilt by CMR Turbo...$1,175

I know we're on the opposite side of the country, but you can still get an idea on the cost.

Happy Hunting.:ar:

Great post Foz, prices and everything.

I finally ended up getting covered under warantee (wish I could spell ). So it's another Mazda reman for 20k-30k miles :rolleyes:

After that I think I'll give Ivan or pineapple a call.

Guys need your help i'm looking at buying a 93 with an o-ring failure at least thats what the guy i'm buying it from says it has wrong with it. Wanted to know if there is a good shop close to the Indy area for a rebuild, Something reasonable, not to expensive and can do nice work and porting and etc. Please gotta help me out getting the car for a good deal just has the o-ring problem. Is there anything else that I might be looking to do with an o-ring problem. Or just a rebuild?


Thanks

I am getting a rebuild at Rotorsports Racing Kannapolis, NC. Hope to get it back next week (8 weeks w/o the car). I am looking forward to driving the car again and will let you know about the results. (Rebuild, ACT clutch, SS brake and oil return lines, RB Catback, Vitron hose replacement, gauges, replace all hoses and fluids ~$7000). First work of this type on car since bought in '93'. If I can get 5-10 yrs service I will be happy, cause I will probally be dead in 10. Then my son can have it.

Kdr
 
My KDR/Malloy recently failed. Had 18000 miles/18 months. Apex seal failed from detonation due to boiling coolant. I'm not surpised that my failure was not covered under warranty.

What's surprising is that at teardown, I had my current engine builder verify engine mods that I paid KDR extra for when I was having Kim Barninger tear down and build up a Malloy reman motor purchased from Ray Crowe @ Malloy Mazda.

These extra mods were: eccentric shaft oil mod, ported oil passages, silicone o-ring coolant seals, ported water passages, and a healthy streetport.

My current engine builder reported seeing stock-looking water seals, stock water passages (not enlarged), and very small intake/exhaust port job.

Apparently, the eccentric shaft oil jet mod was done, as was the enlarged oil passages.

I'm getting this info second-hand from my current builder; I have not seen with my own eyes the old KDR/Malloy motor parts.

FWIW, Dave Barninger promised me a DVD of Kim tearing down the Malloy reman, and buidling up the motor with the mods I paid for. I never received a DVD.

Draw your own conclusions.

Last quote I got from Rick was about $6000. That includes 3mm seals, street port and upgraded water jacket all done on a Mazda reman.

badddrx7 08-07-04 12:53 PM

I also have a Hayes street port rebuild about the very same time BadAss 7 did his and spoke to Don personally. I also told him of the bad press. Mine now has over 13k miles on it and it's a single turbo. Very strong, good vacuum and no leaks.

Tom

REXDEX 08-07-04 04:00 PM

KDR is rebuilding mine at this time.
3mm Apex seals, streetport, eccentric shaft oil mod, ported passages and
Skips anitdet. mod. New hoses, plugs, wires, and ACT clutch.
To the sum of around $7000.
I'm sure I'll be happy. Cross those fingers.

7racer 08-08-04 01:55 PM

Sleep sad to hear about KDR and the parts in your engine after the tear down.

When I lived in L.A. Cali, I used Rotary Power in Gardena...on the up and up and Jeff is one of the old school guys who use to drag race the rotary.

Now that I live in Texas I have been using Marvelspeed in Rowlett...same kinda of thing. Small shop but great service (albeit alil slow) but they do a very good job. Don Marvel knows Jeff McCall from the drag racing days.

However, I'm lucky here in Texas. Rotary Performance is here as well as Gotham Racing.

In retrospect, I should have just installed a plain old Mazda reman, and resumed lapping with the same setup as before. Naw, I had to get greedy. Oh well. Not making that mistake again. This engine is being rebuilt with a new rotor and rotor housing. Having a proper large streetport done (as it should have been with the KDR job). The only change this time is coolant conversion to Evans NPG+, and stock main pulley swapped in for the RP underdrive main pulley (to speed up the water pump flow rate). Hope to be back on the road by September, and resume lapping in October (warm temps won't be a factor in the fall).

rzograbian 08-09-04 02:40 PM

i had my motor rebuilt from Jeff and Alan from Rotary Power in Gardena......... they are the best when it comes to motors... and he gave me a lot of discounts!! i had my complete motor (new rotor housings, waterpump, bearings, and a lot more shit including a new tranny install) for about $6-7k........ everything on my motor is BRAND new! he is also really good at answering any questions..... but if you need a motor rebuild, call him soon, there was a 3 month wait when i signed up but it was worth it!!

ill scan my receipt later on!

Kaotic Dan 08-14-04 10:38 PM

Pineapple Racing is the shit! My motor is strong, his customer service was above expectations. I couldn't be happier. About 20k and running better than ever. Large Port, 3mm Hurley seals, etc.

Devilish 08-21-04 03:13 AM

Rotorsports Racing in NC did mine, and the engine has been great. Bryan builds (or was bulding when I was there last) all the Diasio (sp?) race engines. He also does 3-rotors. Very nice guy.

On a side note, how pathetic is it that we all need engine rebuilds eventually? My friend's '93 Eclipse GSX has over 160,000 original miles and it still makes stupid power. Sigh.

HeX 08-21-04 07:54 PM

So who's the best? I'm ready to take my 13brew for some major cosmetic surgery later this month.
