hey guys, i mean i know that everyone else makes manifold for better turbos suck as t3 t4 ect..

but i mean with as many people with 18g's i would have to think that someone would have to make an aftermarket 18g manifold

if anyone has any information on this... post it up

I would think that you could get a log mani or something of the sorts with a t28 flange on it. I don't really think it'd be worth while though as an upgrade. I think ramhorn style would be a waste of time and money for the turbo...You're never going to make big power with it.

I run the greddy 18G on my Si...I'm not ******* it at all...just tossing in my .02.

 

I would tend to agree. the HKS T28 or similar style manifold would do much better than any ramhorm style or 321 guage steel manifold. It would be best to stay with that manifold you have or change to the HKS if need to, and still keep that turbo. The Equal length in your case would show little benefit, and if then, only in the brief upper rpm band
