[KMSCD]

I am planing on turning up the fuel pump and maybe getting a 16cm housing for the trubo will I need a intercooler and if not at what point will I need a intercooler also will not having one affect the life span of my motor

I am also planning on putting 315 or 305 on it with w 4inch or 6inch lift this truck will be our offroader



also exhust and air intake where can I get a after market on for my year

I ran a PDR HX35, ported 18cm, stock injectors, and a pump flowing ~125mm/ stroke- 50% or so over stock. I only needed an intercooler a few times (got into EGT issues) and would peg a 40psi gauge. My advice is, watch your EGTs, and if you consistently get too hot for the situtaion, then yes, you need it. If you stay under 1300 or so all day long, you may not see much benefit.



Though bgilbert says he gained all kinds of bottom end torque when he went intercooeld on his 89... ... That may come in handy off-roading.

My 90 scooted along just fine without one and it was fast enough to surprise those pesky 6. 0's. I did have to watch the EGT gauge but I was running an all stock turbo.

Even with an IC the dang things get hot w/out engough turbo.
