The turbo is a t-70(70mm) small shaft due to the fact that at pressures below 20psi(which happens to be enough for about 425whp on the renesis) a bigshaft isn't necessary and the small shaft will spool up way faster(reduced shaft mass). I expect I should have full boost between 3000-4000rpms depending on the gear in which the car is at(higher gear=faster spool). This is about 1000 higher than the greddy. This is low lag for me considering the car revs to 9k and when you shift up there it falls to about 7k. I don't think there is a point in having all the boost down low if you're never going to use it, when you're down in the rev range you're ussually cruising not racing and if you want to race all you have to do is downshift. The turbine wheel is a p-trim and the a/r ration for the rear housing is 0.84. I might change it to a larger 0.96 or such later on because it allows more horsepower from the same boost and it raises turbo lag by about 300rpms which I like,personally, because when I'm cruising I'll have the same fuel economy as without the turbo(no boost=no extra fuel). The intercooler is a bar&plate 29X10X3". which is good for about 550bhp or 480whp. The wastegate is a HKS 60mm and is rated for 1000hp which will give me lots of room to work with and better control of boost since Rotaries breathe so much. I expect the kit to be in the car by the end of september and I should have some dyno numbers by mid to late october. For know thats all I'm stating so don't ask for expected HP/boost figures, those will come when all is in the car and proven. Thanks to everyone for the interest, I'll keep you posted!!!

The last reply I posted before is in reference to the "minnesota mystery turbo kit" in case everyone is wondering. Thanks again

Oh dear... this thread is making it VERY difficult to resist the urge to start a custom turbo project of my own...
What I really find hard to swallow is that even all these custom turbos on the Renesis won't even come close to touching a moderatly moded SRT-4. Those badboys put a 50 trim or a GT30R in and they are getting 500-600whp with little effort. We have to go 3 rotor to get in that neighborhood!

I HATE having to resort to the "its still a Neon" excuse. That's LAME!!! We're just stuck with an engine that's not made for those kind of HP numbers. The simple fact is that if you only want to autocross, then you should stick with the GReddy in the first place. The SOLE reason for these larger turbos is drag racing - legal or otherwise.

Yep. We all agree the 8 is a better overall car. Its just that some of those econo-boxes put down insane numbers with very little effort.
Yes, there are several 600whp SRT-4s here in town. I've been destroyed by nearly all of them! Nothing like the sound of a GT30r spooling to let you know you're about to get waxed by a 600whp skittle... They aren't doing any interal strengthening. Of course, no one yet knows the longetivity of these monsters, either.

I dont know a lot about turbos but on the "how long will the srt 4s last" subject vs. rotary dependability...
Don't rotaries take forced induction rediculously well if done correctly?
I wanted to stay N/A but I think by the time my warranty is gone it'll be time to throw a GReddy in. I don't want a lot more power, just enough to put a smile on my face more than this car already does. Twisty smile vs. power smile. Why not both!?
Sorry for the hijack...the talk of the srt 4s popped that question up and i thought id ask.
BOT: GOOD LUCK WITH THE TURBO.

ChrisRX8PR.......I was wondering when you were going to post about your setup, looking good! Nice to see more guys go custom, keep us updated. 
RGonza, I see you guys are rockin' the front mount setup now, are you guys using the same turbo?
Swift, that's SEMA material right there!
Don't want to step on any toes, but I was thinking it would be a good idea to have everyone post their custom setup in one spot. There isn't a crazy amount of people going custom. I thought it would be cool if we're going to share, why not pool all the ideas together?
Just thinking out loud, what do you think?

No one says srt-4.
If it really bothers you just buy a motorcycle and walk on srt-4s all day long.

That way any member interested in doing a custom setup wont have to search through the entire forum to get the information on what works and what doesn't. We should all post our experiences, good or bad, it still helps out others. I'll be working on the install around the second week in september so expect more pics of the setup then. I also have some pics of the process which I'll post later on. Thanks for the support!

the custom thread should only have pictures of the setup dyno sheets and the actual setup. there shouldnt be discussions in the thread so its alot less to sift through if a question is needed to be asked they can use pms to not clog the thread.

200hp:300lbs does not equel 600hp:2,600lbs
NO COMPARISON!
There are so many newbies on bikes that dont know how to ride out there...

Not much has happened since the 21st that I know of. The turbo car has Red and Black leather seats though now 
that's got to add what 15 horses right there!
I traded him with for his black set...I'm making an RX-8 love seat, Computer chair, and maybe an electronic recliner.
