I just installed a Subaru 2.5L out of a Legacy in my Baja bug. it seem that the rev limiter is set to 4200rpms is there any way to raise it up to around 6000 rpms ?

That rev limiter you are hitting is "limp mode". A lack of a VSS signal will put the car in limp mode.

There's a pin that needs to be grounded so the ECU doesn't look for the auto trans.
Also need to ground a pin to tell the ECU the manual trans is in gear, unless you used a Subaru trans, in which case you can just hook up the switch.

You can find the FSM for 99 here:

Look in the wiring diagram section. ECU pinout should be in there. If not there look in OBD2 diagnostics under troubleshooting.

Nice rig....Does the radiator function well at its present location?? IMO, it looks a bit awkward where it is mounted. You would get better air flow if you swapped radiator and spare tire mounting  locations. Something to think about.

the radiator seems to work fine. it does 80mph all day long. I wanted to keep the weight down low.
