A straight T4 on a 2 liter motor or smaller would be super laggy.sentragtr20 said:How much is the GT35/40??
If you factor thr price differcnce the t-04 is the best for the money. And yes they make a t-04 with ball bearings.
On the Gt35/40 and GT30/37 what is the exhaust and intake a/r??
When you say spools, what exactly do you mean?sentragtr20 said:A t-04 spools at 4000rpms which not really laggy. And yes it is a t4.
Well if you plan on running 30psi you'll have to have a T04 that's on the large size to make it efficient up in that boost range. And if that's what your looking for you're looking at hitting full boost at 5k RPMs. THat's if you have a motor that could really handle 30psi with a large T04.sentragtr20 said:We are probally using two definitions. Do you know what a t-04 would spool at if I was wanting to run 30psi??
Or the Gt30/37 spool rate at the same psi??
I was planning on running 30psi or more when I get my engine done. I am building it before I accually go turbo.
Chris Allen's car has a GTiR motor in it. He has pistons, rods, cams but just realize when you are at that boost it may not be very reliable. Chris made about 500whp, not sure if that's your goal or 600whp? Those type of numbers are where you'd consider block sleeving, and definitely head studs. If you want your head to seal with that much boost you may have to use a copper head gasket and it may weap during normal use.sentragtr20 said:I want a least 600hp. I wont be running 30psi all the time. Just at the track. I dont think I will be spending more money than a new WRX. All I am going to get is pistons,rods,cams,valves,valve springs, retainers,72lb injectors,ect...
Chris Allen ran 2bars of boost(29.0 psi) with less mods.
His only problem was the tranny So if I can some how take the gear box off a bluebird and exchange it. Then shotpeed it ,and cryogeenitcs.I think I will be fine..
Like I said I will only run that at the track, not all the time I will only run 18psi..
600whp with 24psi? That turbo must be bigger than a T4 or does he have a bigger motor?sentragtr20 said:I also know a guy that make far more horses with less boost. But he has far more money in to the engine. He made about 600hp with only 24lbs.
Plus another guy that makes the same hp as chris allen,with a us. spec sr20. So the gti-r part is not a factor.
I have a primera sr20.
How would the transmission get stressed?? How about i shotpeed it,and cryogenics.
I'm not really sure. But I know there are others on this board that can answer this question. Anyone?sentragtr20 said:Thanx for the help,but I will need all the help and advice as I can get. So if I ask stupid questions,bare with me. Thise stupid questions are need for me to ask.
Here is one right now. Will parts from a sr20 (rwd) fit onto a sr20 (fwd) like cams ect..
