Hey guys, iam almost done with the conversion of my '90 4cyl. Protege to a v6 powered... everything fine exept the cooling and braking...
The original radiator fits in but the relocation of the hoses is a big problem and the engine got contact to the radiator. So i need help to find a better fitted radiator because i dont want to cut the front to get the original to fit.
600mm x 390mm x 60mm is the possible space for the radiator.
braking problem:
Got ABS and master braking cylinder from a mx3 v6. If the engine runs and i am drive a few meters. My brakes become Solid... if i stop and take off the brakebooster hose... the brakes become loose

Any ideas? Hope anyone can help me.

I had that same problem with the brakes in my MX3- fixed it by replacing the brake booster.

Did you forget the check valve in the vac line to the booster?

check valve is okay, it is the hose from the mx3 v6... engine is a 1993 2.5 KLDE
