Help Me Decide On A Turbo

Polygon · 12-16-2007, 03:13 PM

This is for my GTC. It has a 2.2L SOHC. It will have a good deal of head work done and my target is 350WHP. Here are a few maps, I'm not too good at reading these things but these are the best eight, to my knowledge, that I could find.

It depends on what kind of budget you're on for one...also, can you give me more about the engine like redline, compression, etc...old dyno graphs would help.

So far though, i'm leaning towards a T3 Super 60 or a T3/T04b 50 trim. Either way you'll have fast spool and enough turbo left to pull through the top end. I'm not familiar with much besides Hondas so after i know more about the engine this is going on, i can be of better assistance.

Well, budget is not much of an issue. I'll admit that the S60 was tempting from a price point but I've talked to other TD guys that have run both, they said they'd never use anything but a DBB GT again.

The redline starts a 5k and ends at 7k. The engine will be fully balanced and blueprinted so I would guess about 6,300 with the head work. All the info should be at the top of that link. I sadly don't have any dyno graphs. It would have been nice to get a baseline before I started but it's too late for that now.

If money isn't a real issue, then i'd look into the GT2871R. Take your pic of the .63 or .82 ar. I think that for your setup with lower revs, the .63 would be the best turbine choice.

Yeah, money isn't an issue and the GT series is all I want. I had someone suggest the Super60 which seems like an alright choice since it is cheaper but I should know better since most TD guys are cheap asses. After talking with a few people with TD's and GT's I will get he GT no matter what.

This is good news though, it means I am reading these right. Sadly I can't use the GT28 with the header I'm getting. I have to go with a GT30 since it can be swapped into a Chrysler housing. That's nice though since I think I can get it in a .63 A/R and I'll have more head room for power. Here's the compressor map:
