Hi i have a 94 acura integra gsr with 100,000 miles on it. And i am thinking of going turbo. My friend is going to sell his gsx stock turbo off his Mitsubishi it is T25. I was wondering if anyone could give me feed back and tell me if that's going to work on my integra gsr safe on a stock engine or not? Will it work and where would i get pipes for it? Also would it be wise for me to drop a turbo or should i prep for turbo first like cast iron headers and rods. And plz dont give me the link to a site all about turbos i alredy read it a lot of times, but i want to find out about the Mitsubishi turbo on my car and if it will work.Thanx.

Yes it will work with your stock block. It's a pretty small turbo, so it will be good for low end hp and torque, but won't be that good for top end power. But still, a turbo is a turbo. And if you want it to work well and still be reliable, you're still going to have to get it tuned.

Cast iron headers? You don't use a header with a turbo, you use a turbo manifold. Honestly, I think it'd be pointless to build your engine for such a small turbo; though I'm sure many others will disagree. But if you do decide to build the engine, keep it at the stock (or around the stock) compression ratio; otherwise you'll only gain a few hp but a little more torque.

Thanx's dude. U helped a lot.

boosting the t25 on the b18c1 is a waste of time and money spent. do your research.
