Title: Your thoughts please
Post by: CTworkinprogress on June 15, 2010, 06:54:58 PM
Hi.  As you can probably tell i\'m new to the RX scene so would like to know some thoughts on my current setup, good, bad or horrific!!
 
I currently have a street port with a T88, full 4 inch custom pipe (which is so loud it hurts to drive) and other bits to go with this setup.  The engine is not run in yet after re-build (long story) so no boost yet, still on cruise map, but I\'m already thinking of changing the turbo and exhaust as have heard about horrendous lag, and the fact that it is nigh on impossible to get a mid section silencer fitted this exhaust.  
 
As i say I have not run it in yet so it may be drivable (and fun) but just wanted to hear some experience of this type of setup.
 
Cheers

nothing wrong with that setup, the 4inch will help with power and a little bit with spool, its all the other stuff we need more info on.

Your fuel setup, any water injection, what ecu, any pics?

As far as I know, the largest Trust make is 3.5inch/90mm. Same goes for most other Jap brand exhausts. If you need a 4inch one you will probably have to get one made.

Tried WGT and he sounded surprised that it had that size pipe, and he could make one but would take months and he said it wouldn\'t make any difference.  Guess I\'ll need to try elsewhere.
 
Any other views on the setup, and anyone else running this type of older style gear?

And they have told me will probably be too big for the application.  
 
Anyone else running one of these silencers or something similar?

You just weld a 4 inch silencer box into the mid pipe.
Or swap out the whole exhaust. Are you sure its a 4 inch DP?
Or if like your saying you are worried about lag, then just wait till you change turbo.
