Unless FEED makes two final drives, getting it would be a step in the wrong direction. You'd want to get a 4.1 Final Drive or so. Going to the 4.7 would make it worse than stock. NA the 4.7 would be very beneficial.

Exactly how i see it, and going to a smaller ratio would be more cost effective than swapping the entire tranny out.

swift21

this is my turbo set up....

Moostafa29

^13b REW?? If that is yours, VERY nice. But I honestly want to see more people taking the Renesis to the limits.

swift21

That is the Renesis Motor.....I am trying to develop that throttle body for peep's to buy. thanks for the love moostafa

Moostafa29

Nice, can you get a little closer?

mike1324a

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.

silverwolf

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.

Swift21, did you have to modify you hood to hold this turbo or is the fitment no problem at all?

I see your hood is vented Swift. Very nice looking turbo setup indeed.

Would like to see some closer pics too.

I see the trend is going to purple accenting

swift21

hahaha purple is correct, ALX i dont have any clearence issues at all, i will get more detailed pics soon, thanks for the love

MadDog

haha. Thread sucessfully hijaked.

Ajax

swift, start a new thread with pics of your project. I'm sure that alone would generate a ton of interest.

truemagellen

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

Moostafa29

Whats the ETA for completion?

Moostafa29

Sorry to go back to the final gear thing, but just out of curiousity, have any of the people with turbos tried launching in 2nd instead of 1st?

swoope

i think that would be ugly, very ugly... that is a huge difference in ratio...

and the stress on the transmission would be huge..

beers

shawn81

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.

Moostafa29

Oh ok, thanks. I didn't think it was a good idea, but was wondering if someone was brave enough to attempt it.

rgonza

Some pic of garage Renesis TurboCharged custom turbo.

The second gear is a known weakness is the 8's transmission. The Puerto Rican guys are all replacing it. From my understanding they are machining it or CNCing it.

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!

truemagellen

You are the inspiration btw and I'm pretty sure you know the engineer personally

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!!!
