hey all, each time i come into this area, i find sooo much insightfull information, and i just wanna say thanx to everyone for all of that info. I rarely post here bc all of my answers are basically right there.

Anywoo this is basically a question about any area shops' reputations'. I am going for a rebuild in late November, and was wondering if any of you had any dealings, or know any of these rotary shops (or any of their chief mechs)? How would you rate them/which would be a good place? Heres all of the places in my general area (or as far as i'd like to drive)

Rotorsports Racing: $4,000
(North Carolina)
features new rotor housings, upgraded apex seals with heavy duty springs, competition oil seal springs, new oil pump and chain, high pressure oil regulator, and improved design high flow main bearings, streetport

Pettit Racing: $ 3,200
(Florida)
lapped sidehousings,Main and rotor bearings are clearanced, Oil system mods to front housing and oil passages (improves oil flow. . etc). E-shaft mods, factory sealed oil pan and front cover, streetport, "3-mm seals"

N-tech: $2,300
there wasnt a description, so i take its a basic rebuild

I've read in a few different threads that Pettits cold air system sucks (for its cost), so would that technically reflect their quality in their motors? I know they have a "great" record in racing, which is an added bonus if their quality extends to peoples cars, and not just theirs. I have only heard great accolades in Rotor Sports favor, as everyone who got a rebuild from them couldnt be happier. And finally N-tech, i spoke with them on the phone, and the person i spoke to there was pretty cool and answered all o fmy questions. Of course a rebuild is a big thing, and dropping basically $5,000 into a motor is humongous (at least to me). So any help would be greatly appreciated!!

Thanx,
Chris

Also, if any of you guys have any other suggestions, and the shop is in the south-eastern sect of the US, please let me know!!!

 

I just sent my engine off to a guy in Orlando( pretty close to where you are) that is doing mine. He is going to do a full rebuild, large street port, completely polish the rotors and rotor housing, and dowel pin the motor for 3K. I'll PM you his number. I've talked to this guy for hours about this stuff and he is very knowledgeable. I'm going to be getting mine back in about 2 weeks and I'll let you know how everything goes but for now if I was you I would at least talk to this guy and get a feel for him.

 

thanks SilverR1, i'll also keep in touch with you in regards to the motor and what not, as I am interested as well. every place i've talked to wants roughly $4,500 or so for everything u just described (mainly the full rebuild) so i'll definately give him a call. I was even considering going to KD Rotary in PA!

I travel to Orlando every few weeks just to hang out, so if i can have a great motor rebuild in a place im comfortable with, it would all work out just fine.

 

I'll purchase a rebuild from Mazda and give them your old core.The mazda reman has new rotor housings and new side housings, the block is speced out by Mazda already etc. it's like new. I will then tear it down upgrade the oil system E- shaft mod, H20 jackets, streetport/polish for 2900-3100. I am doing 3 as we speak.

 

We deal with Mazda directly for both parts and remanufactured engines. Some customers request the factory engine so we install their engines as well as our custom built engines. As for the re-man engines you occassionally will get new rotor housings and possibly a new center housing-I have yet to see one with all new rotor housings, and side housings. The last two engines we received had neither new rotor housings or side housings-both were built in '02. Delco-Remy is now the remanufacturer. FYI we have installed 16 Mazda remans so far this year, 5 had new rotor housings- 1 had a poorly ported center housing that had not been resurfaced. For what its worth the reman warranty is void if you have ANY mods. Generally the engines are OK but lack the necessary preparation for improved reliability or higher HP applications. Once again you do get what you pay for.

 

On all but one I have taken apart have had new rotor housings. I also deal with Mazda directly and have been doing so for 20 years. Of course any engine that is taken apart will be void of the MAZDA warranty but not the engine builders. Lastly, I would encourage individuals who are going to purchase an engine to look closely at the posts about engine builders and if the customers were satisfied. You will find mine is impeccable. I remember a recent post with porting (pictures supplied) that was done incorrectly. The shop basically told him to "to bad"...Competition is a great thing.......if you are overpriced people will figure it out and move on...

 

Yes, competition is a great concept and we welcome it! We also avidly participate in competition both on and off the track & have been prepping and racing rotary vehicles for well over 20 years. R&D doesn't come free, the price a business establishes for their services is as varied as the business itself. We stand 100% in front & behind all of our work- we have no control over what our competitors do, but we do have a strong reputation both with our customers and in our racing endeavors. We have also been selected by a racecar manufacturer as the engine supplier for their new C-Sports racer powered by a 12A BP/drysump equipped full raceprepped rotary engine. They contracted us to build 30 engines this year alone. Certainly the $13K per price tag wasn't as much an issue as quality and performance.

 

r0t0rhead, for What its worth, i've been talking to a gentleman named Brain from Rotorsports, and he has answered all of my questions beyond expectation, and he also sent me pix of racers' that their building motors for, which was nice.

I've been contacting mainly 3 rebuilders in my area including rotorsports, and have been talking to them on basically a regular basis and each rep from each respective shop knows what they are talking about, and do take time to answer my emails. But only Brain from rotorsports offered to pick me up/drop me off from the airport when i hinted that i was gunna have to fly back/back home. I didnt ask him to, but he did offer, which was nice. The other 2 companies i have emailed, did reply, and did answer the emails, but their responses for the most part were quite frugal. I know they get lots of emails each day, which i cant blame since they are reputable companies, but some of the emails werent even sentences (some were just part number and price)

I hope i dont seem like im biased, but im just speaking from what i have personally observed/encountered. I would love to check out your work, Mr. RX7tt, but VA is a little too far for me unfortunately. . im basically near Miami right now. But i am planning on getting a second FD next year, and my first mod for it will be a new motor, so we'll wait and see

 

rotorhead-I would like some info on the rotor sports rebuild. My freakin coolant seal is blown...looks like it's rebuild-thirty.
I figure Imight as well beef the engine up a little if I'm to face the misery of a rebuild after only 65K. I bought the car 14K ago and it has run great until now...I guess next time I will put in a better temp guage and cooling mods..I would also like to have the engine ported while shes on the operating table. Gimme a holler if you don't mind. Thanx matt@indoorsportsamerica.com

 

How much would it cost me for a rebuild from Mazda?
