Is it possible? :p - What sort of upgrade path would you be looking at?

JoeD

"reliable" is a relative term.

do a search on this. youll find all the info you are looking for.

skunks

sure its possible... with a V-8 conversion!!!

Zulu

haha.

Ok forget reliable, what's the upgrade path sticking with a rotary?


For the BIG HP guys & V8 swap people, all using Corvette rear-ends or just 3rd party axels? Transmissions hold up ok?

skunks

id say to go for a big turbo upgrade, but even then you gotta get fuel upgrade as well as boost control, computer as well as get it tuned and even then it will not be as relible as a V-8. the displacement will go up with a V-8 though so you cant really brag about the hp to liter argument but who the hell cares when you can put out 500hp n/a or a blazing 600-700hp like jimlab???

hahah, you guys are funny.

You don't ned single, and what the hell kind of comment is v8 cnversioin. you can get 400 at flywheel.(340 rwhp) with basic bolt-ons. not even a need to port the engine. just stick on intercooler, 13 lbs of boost. Power FC, open exhaust, intake. and voila. You have it. You can use stock clutch, diff, etc. Just try not to launch the car. heheh

JoeD

and still be "reliable"?? no. but it is possible with stock turbos.

he was asking for a reliable way, and did not mention any price range. the most reliable way will be to get rid of the stock turbos and system. for the most reliability, go single with a ported motor. run about 10 PSI on the single, and that will get you 340 RWHP. that is the most reliable way of doing it.

I'd buy a Z06...that's 405 horsepower at the crank, and pretty reliable

KZ1

well if you want to be picky, stock setup is not reliable. and many people have run a long time at 13lbs on stock twins. WIth a PFC this is very reliable.

Zulu

hehe, everybody has a different opinion eh?

Well thanks for all the input.

Stock turbos are reliable when non-sequential - but the sequentials are too much fun. What's more fun than a 350 rwhp sequential turbo FD? Spend $8 grand and get a ported motor and a nice small single (T04E, T04S or RX6) run modest boost and you have a reliable monster. I spent $5 grand of the way - don't have the other $3 grand to go the rest - FDs are expensive 400 flywheel hp is very possible with just bolt-ons and 13 psi.

I have a dyno proven output of 330hp at the rear wheels, uncorrected for temp/altitude, made on a 92 degee day. Stock engine, stock turbos. Totally reliable. No problems as of yet. Since the dyno, I've adjusted tuning a bit and am now hitting 340 with much room to spare in terms of a/f ratio. On the same dyno, a brand new M5 laid down a 330hp even hp pass...US cars are what, 394hp at the flywheel? So..I figure I'm making an even 400hp at the flywheel. Very doable. Check out my mods list.

Yeah its possible and just as reliable as stock if tuned correctly. Either way the car is high maintence, but you can't have everything Take a look at my mods, that pretty much covers it. 365rwhp 352rwtq @16psi on the dyno with crappy plugs. Bigger turbo and I could have 465rwhp at the same amount of boost.

Oh and v-8 conversion is cool and all and I respect the guys who have spent their time doing a great job making it work. But to me it is kinda like performing a sex change, you don't want to drive around a transvesite rx7 do you? just kidding guys
