Ken,

I not turbo god like SDF,

Heres wat I know.

First of all, you must decide wat you want from the turbo.

You want response or hi boost or can pull long, etc.

Each requirement have their own mods.

Faster response and can boost higher?

I think you should change or port the compressor housing and change to larger impallers (trim wheel).

DO not change the stock exhaust housing and turbine.

what mods can be done if i want to be able to pull long?

also i herd ppl say u can actually mod the fins or some internal parts to make turbo spoling sound louder, is that true?

Louder spool?

DOn't use Air filter. :D

Pull longer?

If not mistaken, change/port to larger exhuast housing without touching the compressor side.

is there any down side by porting the housing.. e.g. gain more in pulling but loose more in....?

not using filter i think not reasonable la.. i ask becos i was in a vtec turbo with ball bearing turbine and the sound is amazing.. just like in an aircraft.. he was using apexi open pod but i think thats not the only reason is it ecos of bal bearing turbo?

 

[Joeker]

Ball bearing spools at least 500rpm faster. Spool louder? no idea.

Ken,

Ipoh I don know.

But KL, got few good places. But I strongly support Tong.

I think you have to get spare turbo because it takes 1 day at least.

Cost, for my Garrett T25, it was RM200~300 at Tong.

Tong quite lansi on the phone. If you call and ask this and ask that, he won't tiew you wan.

THe best is go to his shop and talk to the man face to face. Quite frenly.

just tell him to port the exhaust housing?

 

[Joeker]

Go talk to him and tell him wat you want.

He will give you good advise.

Nice guy he is.
