Need some help

[bubba019]

I want to get a T3/04 60 trim turbo. What else do you guys think I need? I've got an Injen CAI, Corksport FMIC with piping, HKS SSQV BOV, Forged Bypass Valve, Corksport downpipe, 2.5" custom exhaust no cats with an HKS hi power muffler 5" tip. My stock turbo manifold cracked the other day so now I need one and I was thinking why not upgrade my turbo while I'm at it. So what else do you guys think I need?

 

[KrayzieFox]

I dunno that much about the T3 turbos, but I'm pretty sure you'd need new FMIC pipes, downpipe, and intake as well as a new turbo manifold. I don't think any of those will transfer over.. but I could be wrong.

 

[bubba019]

Also, would it fit my Corksport downpipe? It's a Borg Warner T40e turbo. And how much would I be able to boost with just the things I mentioned and stock internals?

it'd be cheaper and easier just to replace your manifold. Stock turbo is good enough to blow stock internals so why upgrade?

because i have the opportunity to get a nice turbo for cheap and make more power

I agree. Unless your going to build the engine and boost higher than the stock turbo can, it seems like a waste of money.

Right, and when your shiny new turbo pops your motor, I'm sure you'll be ready to shell out even more cash for a new one. Really, a bigger turbo is just begging for a blown engine with stock internals. I didn't see a mention of any kind of fuel or engine management in your mods list so this leads me to believe you're still running the stock PCM with its bad maps. Enjoy your boost cut..

ok so I need to change my internals...what should my compression rate be??? This turbo is nothing big and the engine is already turbo ready, so why should it be a problem?

Because if you up the boost, the stock internals can't handle it. I don't see the point in going through all the effort of switching out to a different turbo if you're going to keep it at stock boost.. you already have stock boost on the turbo you have now. As far as "turbo ready" then I guess that means all N/A Proteges are "turbo ready" too since they have the same internals. (notcool) If you go forged, go with either 8.5:1 or 9.0:1 for the compression ratio.

x2 on the forged, planning to go forged in a year. Want to take on wrx and evos at the track if that's even possible; let's hope.

 

[KrayzieFox]

The MSP is turbo "capable" but far from turbo "ready". The internals (particularly the rods) are super weak, and stock boost on the GT25R is about all this engine can handle safely. You can up the boost a little bit, but every psi gets you closer and closer to kaboom.

With that said, don't get a bigger turbo unless you can afford new internals as well.

I'm boosting 10 pounds now with no problem. If I do this want to boost at least 16 pounds. It wouldn't make any sense to put all this work and money into it if I'm still gonna boost no more than 10 pounds

I forgot to mention I have an SS AFC with a great map running at 10 pounds

I've been running a T3/T04 60 trim and you will most definitely need to build the FS engine to run over 10psi consistently, otherwise, your asking for trouble. Plus, an afc won't be able to handle the tuning because an afc is just simply a piggyback that tricks the stock ecu. Eliminate the stock ecu with full standalone and you might not have to build the motor, but it would be worth it if you want power. Good luck
Its a fun setup, lots of power in 4th gear if that what your going for.

sidenote__i wouldnt bother using the corksport downpipe. Sell it, and make a custom downpipe. Is your 60trim backhousing (turbine) a ford 5bolt or 4?

Thanks a lot sandspeed, thats the answer I'm looking for. I believe its a 4 bolt. Yea I had a feeling my downpipe would be useless

 

[sandspeed]

no problem! You could easily have a good shop build you a nice downpipe. Let me know when you get the 60 trim installed

 

[bubba019]

yea the thing is money is kinda tight and if i wasn't gonna spend so much money, I would do it but im thinking twice about it now.

You aren't going to get anywhere near 16 PSI with stock internals.

Build the motor, THEN get your t3/t4, and get a solid EMS (i.e. Haltech) if you want to be safe. Piggybacks will only take you so far.

Bottom line: you can't just bolt on over 200hp with these cars and expect reliability. It's simply not possible. The stock PCM and the motor itself (primarily the rods) are your bottlenecks, so it's pretty much imperative that you deal with those first if you want to run 16+ PSI.

Amen.
