MPI MSP car now running 21psi

woweee wow wow! Cool!

Yeah, sounds like Dean's MSP to me.

Forged Internals, modified stock turbo, just like the other guys said.

what kind of turbo? not a t-25 i hope.
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.

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

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.
 
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.

From the outside you will never know.

BTW folks, like said above, the member who's car is being discussed in this thread is Dinospeed. He rarely posts on here.

C-P pistons made to our specs. Longer then stock rods that we cut down to fit the stock crankshaft.


Thanks again

Nick, I know you are aware of my recent work on planning an engine build with the collaboration of my favorite tuning shop, Modern Performance (bowdown)..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....and I cant see forging an engine to run 14 psi..

Would doing the type of work you did to Dean's T-25(GT28 compressor modification) 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...

Can you get your hands a good used GT25 turbo?


Thanks again

Im not too sure...thats something I would have to check out..Would just have to browse the forums for a bit for a MSP guy selling his stocker..Can that same thing not be done to a T3, or is it just easier on a T25?
 
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.

They are currently running two extra injectors pre-throttle body.
He's stated previously that he feels 8psi is the cutoff for the stock injectors on a regular protege, and I believe 12-14 on a Mazdaspeed. I wouldnt go past 12 without the extras, since that is added stress to the stock injectors that just isnt necessary..
 
yeah i have wrx injectors which are drop in 440s but i was just wondering how much i could actually get away with using the stock injectors.

i am going to be running the stock injectors and stock fuel pump with the stock ecu for a short while on the new modified gtrs turbo (3.63 psi) just to see how it runs. If it is no good then ill just go straight to haltech and 440s.

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 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..

I couldn't imagine those LONG turbo runners helping lag much either.
