Brake booster question

Phoenix7 · 06-08-2008, 05:54 PM

I'm looking at the FSM and they don't seem to be different in pressure (if I'm reading right) it says they all (NA and TII) create 312psi of pressure for 44lbs of force from our leg.

I left the stock GTUs booster for the TII swap and never had problems. A local guy has the Wilwood kit and had to disable the ABS because the fronts kept locking up in his TII. Dunno what kind of power you're looking to make out of the streetable 20B-NA though so you may need the brakes in the end you know what your needs are.

What did you upgrade the master cylinder with?

how far along on ths build are you? Looks like there are quite a few GTUs' on here. Don't forget to make a thread about your project.

Revolution Brake is designing a brake kit. I have not decided on a MC yet. I am sure from what I see on their website that one will fit my needs. I am still trying to get them to tell me whether the rear kit has been engineered yet or not. I will probably have to get money in their face first...but very nice guys there.

As for the project, Defined Autoworks has my 20b engine. It is about half way done. We are going with semi pports. So R&D still needs to be done to start on my stuff. Custom ITBs are being engineered now as well. So that part is a long way off still. They will do the engine install and tuning. I am going for a street car. Not a daily driver at all. Maybe 3or 4 track days a year. I also want a bit of a race car bling effect for the street. Like I am going to have ac but no stereo. Full interior and I already have new Recaro Pole Postions for the car.

I have Foamsealed the car. It is currently getting the interior Lizardskined. That is sound and heat absorbtion. Roll bar is being started nextweek. Then by the end of the month all suspension and driving gear will be out for full bushing redo. Going mostly with Mazda comp.

Anyway that tells where we are now. I am starting a thread once I get a bit more done. Here is what it looks like now. Oh yea, just got the engine bay painted.
