HEhe..ok...explain clearly here...
-Our throttle body inlet diameter is 2.7"...
But after BOT...my mechanic modify the "whole piping" to 2"... which mean my intercooler piping to throttle body also 2"....
-Stock Air intake (MAF)diameter is 2.5" ... They make whole piping to 2" also.... which mean 2" piping to turbocharger...Feel like will having air pressure problem !!
Hope you understand ! :):biggrin:

Kuchai lama ma..... Is like that ge lor.... Lolz... Keke...

It's won;t cause much pressure problem. Just boost finish faster.. cause insufficient volume to stall more pressurized air..

Dun look down on the boost number bro... It doesn;t determined on how much horse u achieving... Previously, I was using a medium frame MHI turbo boosting at 0.8 bar... Getting around 18+ WHP. Now that I have changed to ******* Turbo. Slightly bigger with different bearing boosting at 0.4 bar. Achieving anytime more powerful than previously. So, boost number is nothing... It all depends on what's inside ur hood.

However, regardless of what engine, car and turbo u are using... There is only 1 thing u need to remember, u are replacing the internal wastegate with and external wastegate which the exhaust and compressed air acts directly on the wastegate without any reaction media like an actuator. U can either remove the internal wastegate flap and plonk in the wastegate there, or u can close the internal wastegate flap completely and install an external wastegate at the turbo manifold.

But there are more details in the process. Easiest is to close the internal wastegate and use an aftermarket tubular manifold aka banana.

Just effort of lifting hands. For MHI turbo using std manifold without altering the manifold. Here is how u do it...

Anything u don't understand, drop me a PM

For using RAM, usually where is it usually placed to? Do short RAM and long RAM got performance different?
