plymouth voyager?
no that i have my 89 plymouth voyager(turbo) up and running,I was wondering what could i do to give that baby some HP.so far i only installed a performance coil.Im thinking of doing the accel spark plug wires next.would it help if i advanced the timing a little bit?
The best thing to do is buy a good performance PCM, for most applications a stage 2, then go with an adjustable fuel pressure regulator. Also a beneficial add on is to use a front mount inner cooler. This will allow you to run more advance w/o detonation. The number one problem with these 2.5 "high torque" engines is heat transfer due to turbo heating. The smaller mitsu turbo is great for quick spool, but runs out of boost at higher speed, which limits your max. boost potential. If you just add timing and boost levels, then you overheat the turbo, which in turn increases the intake charge temp. This is bad and will lead to engine failure. With a new performance computer you will be able to run more boost. There are a lot of tricks for the 2.2/2.5 turbo engines. they make larger injectors, bigger fuel pumps, BOV, you can build the transaxle either auto or manual with a limited slip diff. only your wallet will stop you.
