Anyone have any experiences with the remans lately, good or bad? I understand they have always been somewhat of a crap shoot as far as quality, but they also seem to go in cycles. I had a(some) bearing(s) go and I don't know if I want to deal with peicing together a good engine from parts in the FS section. I contacted Rotaryresurection and am waiting to hear back from Kevin. I am just trying to get info on all my options available.

So, if you have got a reman lately, can you comment on compression, vacuum etc.? Or If you bought one and sent it off to a rebuilder to look over, did they comment on the quality?

Thanks
Ryan

Im wondering the same here....my coolant seal went to ****. So now im deciding on what to do next.

LS1's are pretty available and always competent

ut oh, this thread is fucked now... be prepared for the attack of the rotary purists

If you have the chance to go with one of Kevin's rebuilds...Do it! I had a great experience with him. Its cheap, easy, and so far everything been prefect with my new motor. Ive got about 6k on it now, runnin it hard, and its showing no signs of giving out. It even started up first try!

I don't want to invest the $10k right now to go LS1, cause you know if I went that route, i'd expect no less than 450 at the wheels.
I suppose it would only be 6 or so if you count salvage value for all my rotary parts, but still...

Poss I'm not sure there are many people that can handle a 450rwhp LS1 or LS6 engine in the FD. In a ZO6 which will be about 400lbs heavier than a FD 400rwhp is out of control and good for 11s with street tires at the track. Remember the dyno curve is much flatter. It's not like a 450rwhp FD where the car will make 150rwhp at 3500 rpms and then 450 at 7700. With just 400rw and racetires you'll hit high 10s with a v8 3d gen. 400rwhp can be had easily with a very small cam, heads, intake and full exhaust along with a tune

I'm sure you knew all of that. If you didn't maybe it'll sway your decision. In the end I'll have sold 13k in performance parts off of my single turbo fd. Just add everything up you'll be surprised.

Wow, does it cost that much todo an LS1 swap?? I wonder if its possible to throw in an LS6 or the new LS7.

From what I have read, you need about 7k to not cut any corners. Heads (1500), cam(400), long tube headers(825), TB & MAF(400) roughly add up to the other 3k. Plus you still need a wide band, software and flash kit, and I'm probably forgetting other supporting mods (fuel injectors?).

Anyway, thanks for the advice Yanni. Right now a 450rwhp LSx car is a pipe dream anyway. Maybe someday though...

Frankly, my car is fun with a ~350rwhp rotary, so I'm in no real hurry.

LS6? I thought that was the 70 Chevelle SS Big Block 454.

crispeed

Last re-man I got had used bearings with about 100k + miles on them. Both rotors had dents from previous apex seal breakage. Other than that all seals and springs were new. Brand new rotor hosings with low mileage side housings.

Motor City RX-7

cris, I assume any dents in the rotor are not suitable for rebuilds...does it throw off the balance of the rotor?

No, but it can cause seal groove clearances to be off or vary, other than that it really makes no difference. Some might argue that it gives carbon an extra place to build up and cause a hot spot under certain conditions, but if your setup is close enough to the ragged edge for this to become a real problem then it doesnt matter anyway because it wont last long regardless.

FD-BOOST

Well what i thought was that the LS6 was the one that came in the Z06 Vette and the Cadillac CTS-V.


And thanx for the info "Poos"

Madmax670

I believe that's the ls7

poss

iTrader: (5)

It may have been the designation for that motor too, but the current designated LS6 engine was in the older Z06s. The 06(?) Z06 will have the LS7 (7.0 Liter). The current regular vettes and GTOs have the LS2 (6.0 liter).

Madmax670

uh... isn't the ls2 a 5.7?

rynberg

No, the LS2 is a 6.0L motor.

Let's keep the thread on topic.

My Mazda reman was purchased from Malloy a few years ago. It had new rotors and housings. Other than that I don't know since I didn't open the motor. Currently it has about 37,000 miles on it and it dynoed 240 hp to the wheels with nothing but a catback and downpipe. No other engine or turbo mods whatsoever.

Only issue I've had was a front cover gasket that began leaking; the paper gasket split. If I did it over the only thing I would do differently is reseal the front cover before installing the motor (my oil pan was already well sealed).

I also have a Malloy reman with around 37000 miles on it. I also have downpipe and catback only aside from some reliability such as AST and silicone hoses. I've never dynoed the car but I'm confident I'd have similar numbers. The fact that my car is relatively stock I'd expect the motor to last a very long time.. at least another 37000 miles easy. I'd like it even more to join the 100k+ club.

I had to replace my engine approximately 2 years ago. The first Mazda reman I received had a bad oil leak that wasn't found until it was fired up, so it was returned. The second reman unit I received was fine and I have approximately 20K on it, and it seems fine. I haven't dyno'ed it so no numbers on it. My original engine lasted 111K and through many track days, so I was happy with that.

I talked with Ray a few weeks ago and he told me that basically useable core has disappeared due to a lot of porting and other mods, therefore most of the parts on the remans are new, thus a price increase has transpired. But hey, if there are two new rotorhousings, for $2500, it is not a real bad deal...

mibad

I only have 2000 miles on my reman from Malloy, so it's a little early to say, but I haven't had any problems so far. Good quality at a good price. $2400 and you can drop it in with the transmission on within a couple of days.

Right, and you can't do that with engines other than remans...

pinknuggit

You don't need all that stuff to have a good running LS1. A stock one will still knock your stocks off. Just find a LS1/T56 pullout with harness and ECU for a few grand, buy some hinson mounts and radiator, and Bam!
There are tons of people who have LS1 FD's with under 3k$ or so cost on engine and swap parts..

mibad

Computer's should come with breathalyzers. I was on my second rum and coke.
I was only pointing out to someone who might not know that you can put the engine and tranny back in together because the FSM says to do them seperately.

As far as remans go, the only reason I went with a reman is that I live close to Malloy and could get my hands on an engine within a few hours. Otherwise I would have definately gone with one of your rebuilds.
