Travis, it is probably on the other board somewhere, but what did you do to compensate for the (loss of) brake booster? How is pedal feel?

DVC

Alex- I'm using an electric booster from http://www.abspowerbrake.com/

It's a bit spendy but affords a no compromise conversion. Works like the setup in the 964. I've driven a lot of these swaps and I highly recommend boosted brakes.

I'm interested. This will be a project of mine down the road.

Do you have any tips on where to find a good LS2?

alex

Thanks, I'll check it out. That is an area that I am not sure about the best way to do things, and there are several different options. I was talking to Tim (dawgz83948) and he said he misses the progressive feel of the stock brakes with his set up, and is looking for a change. For now I may have to settle with anything that will stop me.

Have you considered a dual master cylinder manual brake system? Not a tandem MC but 2 seperate cylinders.

DVC,

My wife has a "vacation" coming up mid - April.
I'm thinking a trip to Daytona, and drive Al's car. He is running the same setup.

(I may have some 948 work to do while I'm there, but WTH?)

alex

Yeah, I am looking at the tilton setup, but IIRC the total cost is fairly high- maybe I am mistaken. I did see a link for a dual wilwood MC for 189 off the 944H board by Greg, but I don't know what else I need with that. Everything else about the swap I have a solid idea of how it should work, but I am just now looking at this aspect of it.

Tilton 72-610 Balance Bar = $159 @ CarSop, Inc.
Steel Mounting Bracket = Fab yourself for close to Nada, or ~$200 with the pushrod
Wilwood master cylinders are ~$79 each
___________
Total = $532 +/-

But, this will still be a Manual brake system. Great for the track, but could be tiring on the street.

alex

I guess ideally, I would like to drive something with a manual setup just to see what it's like. Even though the stock NA doesn't have the best brakes, the progressive feel is tough to beat. A lot of other cars I have driven, you rest your foot on the pedal and your guts are on the windshield.

With manual brakes, a balance bar dual MC with the largest possible rotors and pistons is the way to go.

alex

I am definitely going to do the ls430/boxster S fronts. Would the stock NA fronts work for the rears (I have an 88 NA if that matters)?

joeytoad83

how pricey was the system from abspower, didnt see any prices. also where did you mount the rest of the system.

xschop

NA front calipers are worthless on the rear of any 944 arm because the calipers on the front have 76mm ears and the rears are 94mm.
A bolt-on upgrade would be turbo fronts on the rears with washer/shims OR soon to be released RX7 4x36 calipers with Turbo rear rotors. You'll need 87-up Turbo rear 100mm offset rotors.

alex

OK, thanks, that RX7 rear looks like it is going to be the best choice economically. I'm following that thread closely. It is really cool that you guys have the skill and equipment necessary to work this stuff out for us, what an incredible resource for this community. Thank you for all the effort.

DVC

I recommend keeping an eye on the corvette forum and LS1Tech classifieds. Also an online source that searches wrecking yards.

Sounds like a great vacation Greg!
