GTUs 20B N/A Build Thread

[Christopher W.]

Here is my little project for the side mirrors.

I really like the S5 mirrors....but they do look kind of chunky on the side of the car. I decided to have some side mirror mounting plates made to put some small light weight carbon fiber mirrors. I am still not to sure about the carbon fiber. I don't want to look to ricey. We will see. I will get the side plates powder coated black after I get the correct mounting position for the mirrors.

And no, I am not selling my OEM side mirrors.
















Well, now on to the fun stuff.

Logan, at Defined Autoworks is doing the engine. We have broke apart the engine and found one housing bad. So, we got one. We have three N/A rotors that have been sent out for balancing. Logan is building a custom exhaust. Header will go back to a Borla XR-1 then will split into two. Then there will be two Borlas at the back. We are looking into doing a valve in the exhaust to help with volume levels. It is not being designed for performance so much as keeping the thing civil on the streets until you open up the throttle.

I am not sure how much to talk about here. I don't want to give away any of Logan's suprises. But anyway, I am sure Logan can come on here and give more details if he likes.

Semi PPort
Six independent throttle bodies
Tec3R

Oh yea, I did depower and weld the steering rack the right way.

I hope to have the car to Logan by the middle of next month. I am about four months behind when I thought it was going to be up there. Anyway, maybe get it back in the summer.

We are hoping for 350-380rwhp....maybe more. I am not planning on running the engine up over 8500rmp.

Here is a link to my coilovers..

We will see how these do. Spring rate is 8k front and 6k rear.

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...
