GTUs 20B N/A Build Thread

[Christopher W.]

My first question,

I bought a clutch and pp from Corksport for my TII transmission before I knew I was going the 20B route.

ACT 'XACT' Streetlite Flywheel
ACT Street Performance Clutch Kit

Does anyone see any problem with using this setup if I am going to be around 375rwhp?


My second question:

I remove the heat shields.

I am going to wrap the entire exhaust for the following reason:

1. To help scavaging
2. To reduce heat
3. I think it will give the exhaust a lower tone.

Is there any problem with not putting the heat shields back on?

if you're still going to use the TII tranny with your 20B then keep it and use it...I don't see you prematurely wearing out the clutch at 375hp...unless you like to drag race.

As far as the heatshields......that's a tough call. If you get the really good wraps (cool to the touch) then the shields would just be useless. Also, I assume this car will never see a wet road, right? don't forget some wraps rot when they're wet and it could eventually damage the exhaust.


Did you ever dyno your SC setup?

The SC came to me with a dyno sheet of 225rwhp. I don't remember the TQ numbers. I actually have the sheet around here somewhere.

No rain and no drag racing...Well maybe no drag racing. No clutch dumping drama anyway.

I will definitely be using the best wrap that is available. Thanks for the input..

FerociousP - If you mean no stickers on my car, not a chance. The only stickers are the GTUs stickers. I actually bought four more just in case I need them in the future. Damn, $100 for four from Mazdatrix...
