I didn't miss the title of the forum https://www.nopistons.com/forums/pub...IR#>/smile.gif



Just curious what you guys think about this guys engine swap? I can see the benifits, but it looks like a tonne of work. Would you do it?



RX7 Engine swap

Being that i have owned 6 rx7's and a LS1 powered vette... i feel qualified to answer this one.



The MAIN thing i like about my rotaries is the fact that they rev so freely and to such high RPMs.. Too bad they break alot and can't handle detonation at all... very expensive parts also.





The thing i like about the LS1 is... you get in and turn the key... and it's gonna start and drive EVERYTIME. Huge aftermarket following for parts and upgrades too......Too bad ALL of the stock (Z06 included) clutches are pure ****. Will be replacing the 2 month old Z06 clutch with a Textralia very soon.





Both engines have good points and bad points. It's all in what you want. Doesn't matter what other people think about it.

Would a better clutch at the time of installation not allieviate that problem, or is it inherant in the transmisson?

Plus LS1 FDs sell for quite a profit. Check out v8rx7forum.com.

on a factory clutch set-up... you'll end up bleeding the clutch about once a week if you drive the car really hard. No bullshit. The slave cylinder is shaft mounted inside the bellhousing and transfers all the friction heat from the clutch to the slave. It's about the same if you'd shroud your brake calipers where the heat couldn't get out. When i run thru the gears hard... 1st to 2nd isn't an issue normally, 2nd to 3rd... the pedal hangs about halfway to the floor after the shift... 3rd to 4th.... pedal stays on the floor after the shift for 4-5 seconds..



It is an absolutely shitty clutch set-up design. It might not be as much of an issue on one mounted in an FD due to the huge weight difference it has to accelerate.



go to www.corvetteforum.com and do a search for sticking clutches and you'll see what i mean. *SOME* claim that some of the aftermarket clutchs have no issues with this.... i'll find out soon.

Really? what's the point then?



One set of problems for another

I think there was a Sport Compact Car article (front page) where they back to back test both setups. I regret having neglected to buy it, I still need to track it down.



You are going to get the best answers there I'd imagine.











*for the record, I'm 100% against anything but a rotary in an RX car. https://www.nopistons.com/forums/pub...IR#>/smile.gif

sup greygt-c,

stock clutches can't handle drag radials well.

i've used CARTEK clutch for years with no issues and 1.5x short times on ET street bia ply. the stock z06 clutch is pretty weak for draggin.

i think i'm gonna use new ls7 clutch mated with aluminum ls2 flywheel. it'll be soft like stock with no chatter, but i won't kill it at drag strip. if you will drag, get that text clutch or cartek. there are a bunch of other good ones out there as well.

In that Sport compact car issue, they liked the 13B better.
