Don't waste your money on an aftermarket cam. If you are looking for a little more power then stock find yourself an 88 TBI cam. It's the best "stock" cam out there for these cars and will give you exactly what you are looking for. Cheap tooI just want a little more power than stock and maybe have it a little lopey? I'm gonna be running all stock equipment on my 1989 turbo 2.5. what would you all recommend? duration? lift? thanks in advance :thumb:
Log car, sure it makes a difference. But with a blow through car even the least mechanically minded person can toss an intercooler on it first. Why neuter yourself if the methods are already so well documented? 2.5 mitsu cars suffer from poor engineering which can easily be remedied prior to any major undertakings. When I bought my Lebaron my Hyundai Elantra would run it over in any gear at any speed! Now with a Spirit R/T i/c setup, 2.5" FWD exhaust and a rebuilt Garrett that I did myself it's a much different story. Stick with the basics first:thumb:All stock 85 T1 with MP 460 lift turbo cam = good increase in power , big one when loaded up on a hill , -- really big one
should still work with 7-8 pound mitsy deal
I actually ran it with the Spirit i/c and 2.5" exhaust for a short time, but changed out the turbo when I had to do the valve seals. It was still fairly impressive with the mitsu at stockish boost levels. Spooled incredibly fast and it wasn't boost creeping at all(which goes against common wisdom). But the O2 sensor was TOAST and I couldn't break it loose in the car so I prepped a Garrett to swap in it's place. I do like it better in any event. Boost comes on more predictably and it pulls harder through the RPM's. But I stand by the statement that I would do an intercooler/exhaust before even considering anything else on a 2.5 T1 car. What else can be done to cut 2-3 seconds off of the 1/4 mile time realistically?key words "rebuilt garret" ^^
ya never tried to make a mitsy fast(er)
So what's different about the 2 cams then? Just the sprocket? Because a stock 2.5 cam in a 2.2 engine makes it run like a dog at stock timing as does the reverse. Been there and tried that.you want the 2.2 TBI cam. Doesn't matter if he's using a 2.5. I wouldn't run anything bigger than that with your stock intake, exhaust manny, and turbo. Those and the i/c are choking the motor off enough that an aftermarket cam is going to do nothing for you.
