HOW TO DO AN ADVANCED SEARCH.

For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

RX7 Caliper Swap - Page 2 Empty all bolted up

Post  xschop on Mon Apr 12, 2010 9:35 am

The brackets need M12 x 1.5 x 55 (4ea) Bolts..... 60mm length will do with thick crush washers....
The only thing that is not in the posted drawing is 45* slots near the atachment bolts that clear the RX7 caliper ear bridge reinforcements..... On my prototype bracket it took all of 5 min to grind and test fit against the RX& caliper, so no trimming is needed there....

RX7 Caliper Swap - Page 2 Image007-6

RX7 Caliper Swap - Page 2 Image002-6

RX7 Caliper Swap - Page 2 Image001-4

Also the new drawing gives even more clearance for very minimal RX7 caliper ear trimming to fit the braket snug before bolting to the 944 Arm....

RX7 Caliper Swap - Page 2 Image011-3

Steel CNC'd version gets the Yellow VHT caliper paint....

RX7 Caliper Swap - Page 2 Image010-4

The inner radius in the drawing is perfect and clears the curvature of the 944 trailing arm beautifully....

Yeah, I was thinking of just taking that down with the grinder and painting Ford on it just to really confuse everything.

Do NOT go below the "Z" letter base. You can remove all the lettering, but leave the under letter "bridge" as it houses the cross drilling for the hydraulic ports between those 2 piston chambers directly below the "Z" letter....

10th post, 3rd pic shows this 45* cross-port hole......

Ha, I looked at that 5 times before I saw the F. That raised area is just asking for some kind of custom script, though. Something to really irk the purists more than a Porsche with a Chevy engine, Toyota front brakes (not accelerators, though!) and Mazda rear brakes. I guess all we are missing is some Honda valve covers or something.

Post  xschop on Thu May 13, 2010 9:35 am

I can deal with busted end mills, but the 5 tornadoes this past week and OG&E not restoring the shop power for 3 days sucks....
Anyways got these sets done and am starting on the new billet design Lexus LS430 adapters tonight....

looks amazing... just to be clear though, this is just for 86T rotors and wont work with early N/A rotors right? Im still deciding on what to do for brakes.

Post  xschop on Thu May 13, 2010 4:20 pm

If you change the .903 dimension to 1.12 in the drawing you can put the RX7 calipers on the N/A rotors, BUT you would have to trim even more of the caliper ears off.... These adapters are recessed even more for very minimal caliper trimming and TURBO 299 Diameter rotors and all the pad rides on the rotor sweep.

Has anybody ever flared (SAE) the bubble flare (convex) brake line ends on these cars? It looks like there is enough meat there to mod it for a direct fit to the RX7 caliper inverted 45* flare. Talk about being a frugal bastard.... pirat

Cut off the bubble and you can do an inverted flare, but the lines are dirt cheap, replace those buggers! You can also buy lines with metric and bubble on one end, and inverted flare on the other. Fox body Mustangs use them, I know, I replaced all the brake lines on my wife's last year, I bought the flaring tools to do both, so much easier to buy bulk line and flare them yourself. New ends are dirt cheap too. Smile

would the rx7 calipers be good to use in conjunction with the willwood kit?

if so i'll most likely take those off your hands.

What size wheels are you going to run? I know they fit the 16's no problem. I have a 15" phonie that I can try on mine when I get some time. Over 4,000 miles on this swap and ZERO problems. Those 944 online calipers swap have 41mm pistons and the RX7's have 36mm pistons, so it would be a good match. What are you doing for brake MC/Booster?

what would you recommend running for the mc?
i dont want to do hydro. i'd rather keep the ps pump off my car.
i was thinking one of the wilwood or titon mc's. dont have many other choices.
i dont have a lsx swap, just a 2.7 n/a. im just looking for better brakes.

If keeping the Vac booster, you could upgrade to a Turbo MC and call it a day.

That one? If you really think it would be a good combination with the wilwood calipers I'll take them.

You may want to check your MC part# and verify the bore sizes. What is your car year again and can you verify the MC wasn't already swapped? You can install the RX7 rears and Wilwoods and check pedal feel/throw first with what you've got. That's what I would do.

It's an 85.5 na.

I sent the payment. I doubt it's been changed, probably still the factory mc.

Like I said try it first. Also you may want to look into an inexpensive Wilwood adjustable Bias valve and plumb it to the rear circuit. That way you can adjust the rear pressure to suit whatever MC you put on. I recently rode in Ultrasuave's Turbo 944 with th4 Lexus brakes upfront (43mm pistons) and factory rear 4-pot calipers and it was badass with the stock MC and Vac booster. Your set-up will be serious upgrade for the 2.7L power you are putting down. I will box them and get them in the mail in the morning, Thanks, Rob
