well.
I doesnt matter what you say...about the buying a 951 engine anyway.
everything else does matter! why do you think I should use a T3? I think it is a little too large in the space provided. right above the crossmember and a little toward the back.
If i were to use the T25...Would it still be effective? I wouldnt overboost it would i? It could make 8 psi to redline right? and later on could it make 10 to redline? 15?

Oil is pressure fead to the turbo. Then drips throught the turbo/engine mount and it's connected hose which attaches to the oil pan with a banjo bolt. You will need to keep the turbo above the oil level in the pan. You should do a search (here / Google) for the Callaway 944 turbos. They were NA 944s that were converted to turbo. One of the listers here has one, I'm not sure if he has posted on this thread or not.
I wouldn't get too hung up on how many psi you will use. A higher compression ratio (CR) engine will produce more hp/tq per psi than an engine with a lower CR. Plus the higher CR engine will have more low rpm hp/tq. I could go a lot deeper here, but it would start to overcomplicate things.

Im currently looking at an APEXi controller.
it should do the trick.
Im also pulling off some of the ducts under the car and behind the front spoiler to make room for an intercooler. right now it looks like it will be 18X6X2. should be plenty.

alright guys.
the way I wanted it to work Isnt going to work because the outlet for the intercooler is blocked by AC pipes. You would have to move them and I did on my car and now there is a little leak (no biggie..im taking it off anyway) and since I said i want to do this with very little modification I need an intercooler that is....
if you can find a website that custom makes them...please ask..if you know a friend..please ask..maybe i missed something on ebay?
thankyou.

Well I built a twin turbo 4.5L 928 and used twin t3's I used one step down from a SVO turbine trim, and one step up from the stock compressor trim (custom). Also lightened and clipped turbine wheels and it was awsome. Started spooling at about 1300 rpm with no lag. that setup was recommended to me by a turbo builder. that might be a good idea is to call for a recommendation. That particular setup did start running flat at about 5500 rpm.
A t25 would work. really anything will work, its more a question of how you want it to work. T25's are more designed for streetablility and depending on the trim could be dynomite off the line and a dog above 4000.
At any rate at 8 psi it should be fine. If you go the t25 route you may want to consider a T28 which is a t25 turbine and a t3 compressor side and clip the turbine for less back pressure and use the larger exhaust housing.
Actually I would call a turbo builder and get their recommendation for what type of application you are running.
