yeah moostafa, look really close at the intake manifold and ull see it is not a 13b rews but a custom renesis one. but i think is looks very rx7-esque and i like it alot. Probably the best looking set up ive seen yet imo.

so im now wondering how the project is going. updates? problems benifits how much room you have for the turbo left over? if a bit can we get another ballsy owner to put up a bigger turbo setup? kudos to the creative and gutsy.

that was a very swift hijack of this thread (pun intended :P)
No problem...is he using a big shaft Turbo?...
this setup will maintain the battery in the front...the turbo at an angle so you can watch it run...and be where the stock airbox is

and the stress on the transmission would be huge..

with the transmission we have, NOWAY bro, i have lost my second gear once.....I really didn't do anything to it as they cover the new transmission.. but haveing the turbo will not help if you would of lost a gear... so i am not even going to try.

Granted some of them just said fark it and went with a 3 rotor and an FD tranny
but some of them are using the 3 rotor and the stock RX-8 tranny!

The engineer picked up the pressure sensor today. Not that exciting but when that is one of the last pieces he needs...
Took me on a quick ride in the MS 6 What a way to wake up from a nap!

Hello Everyone,
This comment is a teaser but I am not one to talk without evidence/testing so I will just state some facts and keep project expectation coments to a minimum. 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!!!
