He all I just got a 88 t/c and was wondering what kind of a turbo upgrade can i do? I'm looking at around 250 or so horses nothing to major. I was thinking of a t3/t4 setup. Does any one know where to get some thing like that? of course I will be upgrading to the ranger cam and FMIC, headers and full exhaust.

Its An Ihi So How Should I Go About Upping It? I Don't Want To Push More Than 10psi Out Of It Until I Get The Cam And Exhaust.

just build a forged bottom end before you turn up the pressure or youll be sorry

just have the fuel and timing dialed in right then and go for it!

I am running 17-18 PSI on my 87 TC just fine. I would guess that you can hit 250 HP with that turbo. If you want to get closer to 300, go with a T3 like the earlier turbo coupes had. The ranger cam isn't really necessary, but a good 3" exhaust system is.

to crank up your boost go with a manual boost controller. If i remember from my 2.3 days that you can git about 18 pounds or so on stock injectors and pump before you start to get a fuel cutout going on. 3' is good but an overkill on stock ihi 2.5 duals works and looks great for these cars and keeps nice back pressure. also fmic is a must. get that ic away from that hot ass manifold. bob long makes some grear high flow logs for these things. check him out at www.40bob.com he also guts and rotates the upper intakes.

A 3' exhaust is definitely overkill, but a 3" is not.


"Back-pressure" on a turbo exhaust? Uh...no...you want as free-flowing as possible.

You do realize that 2 2-1/2" pipes flow more air than a single 3"...

So you pretty much say that a 3" exhaust is overkill, but then suggest a dual set-up that flows more but would provide "nice back pressure"..... Hrmmmm....

Check out Stinger Perf for exhaust parts.


The stock bottom end has forged pistons and is pretty stout. For your desired output it is MORE than adequate.

Your fuel system is fine for your expected power levels. You might think of a fuel pump upgrade (190-255lph) should you need to replace the stocker. Make sure your fuel filter has been replaced.

talk to the guys over at turbotbird.com if given the op many of them would go with a 2.5 dual instead of 3 single. says the car just looses its umph.

No...most guys go duals for the looks.... For most 2.3T applications under 350-400hp, you're not going to notice a difference between a single 3" vs a dual 2-1/2" system.

I agree with Chuck, the turbo presents enough backpressure, you want everything after that as open as possible. In addition to looks, a lot of guys go with the duals to get a deeper, more mellow exhaust sound. I love the sound (and performance) of my single 3" dump :-D

On mine I like the "period correct" look of the single twin tip.
I'm rebuilding the exhaust this spring with full single 3" system (custom turbo outlet). Still keeping the twin tip as well.

Inline engines don't sound right with dual mufflers. My old 2.3T Pace Car had a dual system from a previous owner...never was right to me. At least they put a 3" DP on it.

If I repeat something someone else has said, im sorry, but the conflicting info is confusing me a little.

The stock fuel system (Injectors, rail, FPR) is good for roughly 300 hp. Any higher then 18psi and you might want to start thinking about replacing the fuel pump. The stock bottom end can handle anything the IHI or the t-3 can throw at it. Crank up the boost with the gillis valve. http://www.boostvalve.com

Open the exhaust up!!! Weather you go duals or single here is up to you, just be sure that you include a 3" downpipe either way. You can even tell a difference just having a 3" dp on the factory exhaust. I went with a single 3" side-dump, I could feel an incredable power difference in the lower rpms because of the quicker spool. However, the smaller turbo does start to run out of steam at around 5K. Its just the nature of a small turbo. Even with the smaller turbo, I can roast the tires through 3 gears:D .
