angle mount turbos & big boost thanks.

Why would you waste your time with a EJ subi then?

There is much better bases to start with for drags over a subi

Different strokes for different folkes.

wasting time? hardly- torque chasing is easy if you know where to look, and its not with little boost and small exhausts.

ive now just moved onto drags as a focus for the car.

Am I to interpret that meaning MMS press the bends instead of mandrel bending them?

Yuck!

Gimme a china over that

As for the other comments mentioned and mine previously, it is all about application. If you have done everything else and then wanted to fine tune a bit more, than perhaps changing exhaust diameters for the rear section may give you a minor gain.

But I think you would be better off looking at other options (tune, AVCS, dump design, intake etc) which could provide a lot more gains than this.

I agree completely. Except I put it to everyone that instead of looking for gains of very small percentage (like MAYBE 2%) in torque or power, how about looking elsewhere on the car to improve your figures, whether it be drag, circuit or rally. Power and torque figures are not the be all end all of performance. If you want higher numbers on your dyno sheet, run it up at Speedworks on a Dyno Dynamics.

However if you want to go a tenth or more quicker around a circuit you'd be better off spending that money on better tyres, refined suspension and most importantly, brakes that don't fade. Having more low down torque will, yes indeed, help with exit speeds and the like but so will having a car built properly with the right handling package will have your entry, apex and exit speeds significantly higher to begin with.

If you want quicker ET's, suspension rates, ALK, more boost etc. If you're getting more low down torque how will that help you on the strip?? You launch (properly mind you) at more than 5000rpm and everytime you shift you should still have an engine speed of more than 5000rpm so where is the benifit of a smaller rear section?

But let's face facts here. There aren't too many people out there that are prepared nor financial enough to go to lengths required to ensure these things. Assuming a change in diff back section from 3" to 2.5" costs let's say $200. I'd bet that a sway bar, or $200 worth of new bushings would have you going around a track faster, and that an ALK fitted would see a lower Elapsed Time

What if you've already got all that gear?

Chances are though, that if you've done all of that, then you are not running a standard turbo or intercooler and are certainly tuned (with regard to engine) for the mods you've done. If you're talking about a purely street driven car with no need/want/otherwise to go into any form of motorsport, then I'm sorry but you've brought the wrong car.

If like me your doing an EJ207 Twin Scroll conversion then for $400 ish a 2.5" diff back is a small mod to throw on before it gets tuned.
Yes everything else has been done in my case.
I'm also chasing something QUIETER in the choice of muffler.

Its all about what HP level your chasing, what stage of modification your at and what APPLICATION you have in mind for the WRX/STi.

Street driven, point and squirt weapon for me, so its all about low down response
