Re: mods list (SN2BJDM)
Stock Hp at the wheels: 69-70, motor 81-83.
Exhaust is the biggest factor, IF you do the downipe and manifold, I will say 8 HP at the wheels- that stock exhaust is very restrictive. just the cat-back, say 5.
Throttle body, like the 91-93 model? Negligable.
The cam, depends on where you want to get the power at, and which cam you get. With stock valve springs, you won't rev any higher before valve float, but stock Foxes run out of lungs way before that, like at 5G's on the tach. The right cam should get you 5HP wheel, tops.
Cam gear: just dials in where the HP hits. Not a factor until ALOT more modifications.
So, 81+10 = 91 motor, maybe 80 wheel. And that is with your current small valve head, although the bigger may only net you a HP or two.
That is why the guys go with the 2.0 here, gives them closer to 100 wheel/120 motor with the same mods. Actually, you can get that out of a 1.8 high compression motor, but the torque (what you feel) is lower with the 1.8, so many "tuners" here don't go that route.
