Yep.



Ebay, Classifieds, get a custom straight 3" exhaust made out of steel piping and choose a muffler of your choice.

If you are going to be on mitsu turbos for a while, you should go with a ported stock o2 housing, 2.5" downpipe, to a 3" exhaust. People that go with full 3" exhausts on 14b's/16gs usually get boost creep. Which can only be solved by using an open dump o2 housing OR by extensively porting the turbine housing.

why not just buy a high flow header?

"High flow" header on a turbo car doesn't afford you the same benefits as it does on a non turbo. The turbo is a major exhaust restriction that forces more air into the engine to make more power. Think of your engine as an air pump. You force more air in, you get more out which forces more in. A high flow header won't be needed till you are pushing the limits of a 14b. Around 300 horses wheel. Find a 14b and put a "real" 1g turbo on there. While you are at it, port your o2 housing and 1g manifold. A stock manual car is capable of around 300 hundred wheel if you build right and tune well.

a real 1g turbo, i like that i bought a 2g ported manifold already. waiting for my 14b in the mail. do you know what grit to use for porting the o2 housing? also i wanted to set up a external gate eventually , i know you have to buy an o2 with a dump tube and weld the internal gate flapper shut but what else do i need to do? and will it affect performance or just make it sound mean? i love the sound but wanted to know the performance side of it.

An external gate is better capable of controlling the boost level then an internal gate. It eliminates boost creep, which a dump tube will do. External gate will require an aftermarket manifold. If you are going to go to that point, I would move away from a MHI turbo. Possibly t3/t4 hybrid or something similar. Are you looking for a street car/weekend warrior for drag? Maybe you want to take it to a road course? Autocross? That will dictate what kind of turbo you will want. Small turbo will do better for Autocross, 14b sized. Mid turbo for road course, 16g sized. If you can stand a couple hundred rpm of additional lag, a 20g is streetable and bolt on from a 14b. It is also decent for drag use.

Thanks for all the info, seems i am going to be running an internal gate for the moment, But that can always change. i am looking for a street car/ weekend warrior not trying to run 10's I would be happy at low 13's high 12's i figure a 14b would be good enough for these kind of numbers let me know what you think.

A 14b should be good for mid to high 13's with the right mods and tune. Look http://www.dsmtuners.com/1g_dsm_turbo_upgrade_path here for more help.

it should be able to hit low 13's with a good port job, good tune and supporting mods right? phil beers runs 11's on a 14b w/o nitrous.

Sorry I did not except your friend request.But if I had seen this thread I would have..

Pm me if you want to talk auto mods.I know a thing or two about that sort of thing.
