Why not? I built this as a street car. I did not want to add any turbo lag. I kept the stock MSP turbo and reworked it alot. Ported and polished the exhaust side and added a GT28RS comp wheel with a remachined stock comp housing. The spool up is so fast on this car.mp5jeff said:what kind of turbo? not a t-25 i hope.
that's not really a t-25 anymore =), on the stock t-25 , 22psi is way past efficiency that's what i was worried about.MPNick said:Why not? I built this as a street car.

Almost 330whp and 340 wheel torque with 15psi before on the dyno. Now with more tuning and more boost it has to be near 350-360whp and 370-380 wheel torque. This car is a monster.
Stock valves, stock camshafts, stock bolts, stock head gasket, stock fuel pump, stock injectors.
Thanks again

C-P pistons made to our specs. Longer then stock rods that we cut down to fit the stock crankshaft.seatbackfurther said:what kind of pistons and rods are bing used?
Can you get your hands a good used GT25 turbo?KzA said:Nick, I know you are aware of my recent work on planning an engine build myself..The one thing that is holding me back is the fact that I would probably need to replace my turbo, since it would lose efficiency at those higher boost levels....
Would doing the type of work you did to Dean's T-25 help me achieve the boost levels I want with my T-3, and be moire cost efficient than jumping for the full cost of a GT-28RS? Abouyt what do you charge for this turbo work? Its just hard to spend over 1200 on ONE part...
They are currently running two extra injectors pre-throttle body.azian6er said:Hey mpnick im glad to hear you guys are running big boost on dean's msp.
YOu said that you are running the stock fuel pump at this time. Are there any signs of leaning out while you are monitoring things?
You are running the extra injector setup right now correct?
I am just curious because my car is about to come together here very soon and i am contemplating changing out the stock fuel pump or not. I have a very high flow denso pump that i can swap for but it may not be needed according to you.
Also, how much whp do you think our injectors can safely flow without the aid of any additional injector setups?
Im sorry if i was doubtful in the past, you seem to know what is going on here recently.

I say BAD IDEA personally..I cant imagine a steady amount of boost running through that piping wouldnt damage the maf severely, let alone screw with the readings...You COULD get a larger MAF, and tune it with your EMS(Haltech I think you said..) If your gonna go that route MPNick has access to the bigger MAFs which are a little over 3 inches, I think..azian6er said:also what do you all think of putting the maf sensor in a boost pipe line intead of the turbo air inlet pipe?
im just curious because my new turbo has a 4 inch inlet and its going to be balls trying to reduce that down to 2.5 inch for the maf sensor. On the other hand my boost piping is 2.5 inches so it would fit in nicely.

I couldn't imagine those LONG turbo runners helping lag much either.mp5jeff said:i think i might swap out for a smaller turbo on the p5 when i get money, i love having sick topend but lag sucks.
