I am thinking about doing a litle work on my new turbo that I got with the Greddy SOHC kit and needed some help. Just wanted to know if anyone knows of any upgrades or rebuilds that can be doen to give it a little more top end and maybe spool up a little faster.

 

i know that a bigger down-pipe will help a fair bit on both counts, does it have a cat? if so then a strieght pipe will help a lot from what i hear. a full 3" turbo exhaust gives better spooling and top end. throttle bodies help a lot more when turbo'd as well as intake mannifolds. get a turbo specific camshaft, that should help a lot. if its not intercooled you should do that first. get a blowoff valve, those help a lot for boost after shifting, and sound cool too. if it were me i would get a throttle body, blowoff, intercooler, and turbo exhaust to start with

 

Id start by having a custom 2.5" dp made

 

If the 16g is drop in replacement for the mitsu, then they should be a drop in for you.

mitsu turbos and greddy turbos are not the same, they don't have the same bolt patterns at the mani.

I would get real engine mangement(hondata, ems) and open up the breathing on the exhaust end.

 

You can contact forcedperformance.com I think, and they can rebuild the 15G to an 18T compressor, is what they told me before.

 

Or you can ditch the turbo and buy a Garrett T28

 

is the t28 bigger? i was always told they were about the same. don't really know tho cuz greddy won't release info on their turbos.

i would stick with getting better fuel management, ic, bov, exhaust, boost controller, and getting it tuned out.
