Brake swap confusion

bbrewer2005 · Sep 2, 2013

Hello guys,
I'm currently doing a full swap that I'm sure not many people do, a 302 based motor in an actual 96-98 cobra body.
A few things have to be changed around and the only one that has me stumped is the brakes. The car everything is being swapped FROM is a 96v6 chassis with 95gt drivetrain. The soon to be chassis is a 96 cobra.

Ok, so the 4v power steering pump uses hydroboost, and the 95 ps pump doesn't. What do I need to do to make this work? I don't care if I use the hydroboost or not, I'm just trying to do this as cheap as possible. 96 v6 booster with cobra master cylinder? Or is there a way to use the 4 valves ps pump on the 302?

Thanks for any and all help guys. This is the scariest part of the build for me. Heh
Brian

My first question would be why on earth are you swapping out a Cobra 4V motor for a push rod 5.0. Massive downgrade in my opinion. Secondly, why are you fooling around with a V8 SN95 mustang swap when 94-95 mustangs, especially the Cobra versions are worth as much as dog piss and cheap to buy? Am I missing something?

Either go full hydraboost or swap in a sn rack and call it a day

Either

I'm with you. Why?

Probably because he actually wants to make power.

LMFAO

We have been down this road before. The Modular 4V engines are superior to the 94-95 5.0 Pushrod engines. End of discussion.

There is a way to make the hydroboost work. How I'm not exactly sure how but its been done. Some one here had it.

why does everyone always ask why? why doesnt matter. its his car and let the man do whatever he wants with it. what i would do is a 94-95 gt booster and m/c. there is no reason it wont bolt right in, then use the power steering rack from the donor car your getting the engine from. i could also be very wrong too.

Ive got the rack for the 96v6 chassis. Its not hydroboost so I can use that?
Can I just plug the hydroboost ports on the cobra booster? Or do I need to get a different one?

To all others, I bought the cobra with no drive train for a very good price. Just a rolling chassis. My current chassis has quarter panel damage and needs a lot of work.

^ No, it's not the same person.

And we're not going to start any kind of 5.0 vs 4.6 nonsense here.
The OP had a brake question... Let's keep it on topic.

You might be able to find a mark Vlll 4v cheaper and be an easier swap. Then selll all the 5.0 stuff. .

The engine I have is already making more power than a stock 4v, and is relatively fresh. (306 with heads/cam/intake/tune) I'm not opposed to a 4v, I'd love to have a nice B headed termi setup, but this is what I have at the moment. I only have issues with the brakes at this point.

Let me rephrase my original post. My current car, (a 96 v6 chassis, with a 5.0 based motor) is already running mid 12's, but looks like crap. Its got body damage in several places, including both quarter panels. All I'm doing is moving my 12 second setup, into this cobra "rolling" chassis. It (the cobra) did not have a motor or trans, so no, I'm not pulling a good engine out of a nice car to put a 5.0 into. It was just too good of a deal to pass up, and what I'm trying to do here, is take advantage of the cobra braking system without spending an ass ton of money.
Is there any way to use the stock braking system on the v6 chassis, and the cobra chassis, to make a decent braking system without spending a ton of money. I do have the ENTIRE braking AND Power steering system for BOTH cars. Including the power steering pump for the 4v motor. Is there any way to make this work?

Thanks again

no more recommending me to swap to a 4v as thats not going to happen at this time.

Personally i would just roll with the brake system specific to the engine being used.

Magic · Sep 3, 2013

Im sure you can retain the Hyrdoboost setup with the pushrod 5.0 with some custom made lines.

This image is to give you an idea of how the lines are run.

duff daddy · Sep 3, 2013

ANY type of machine/tractor/truck supply shop can make lines to fit. I blew a few on my diesel its just getting all the proportioning right that sucks. Personally I would just stay with whatever motor your working with and go with that brake system. Hydroboost is good but just adds weight effort and another system to fail.

I was suggesting because all the wiring will have get swapped over. I seem it done somewhere. I'll look around see if I find the info.

Good info guys. That helped out a lot. I could probably have a machine shop make some fittings that can screw in to some AN braided lines as duff daddy suggested.
I guess an even easier route would to just use my 96 brake/steering system with the cobra calipers/rotors.

rz5.0 Yeah the wiring is a pita, but not as bad as you would think. I already got the cobra eec and main harness out. (currently trying to sell) The hardest part is figuring what im going to do with these different brake setups. I could make a one off bracket to mount the mini-pump (stock cobra ps pump), that way I wouldnt have to mess with new lines, but that would be a pita too. Either way, pita.

Again, thanks guys. The pics, and link to the corral thread is a big help too. Ill post back with whatever I decided to do.
