hi i'm planning to add a jegs plug in so it will pep up my cherokee 95 4.oL, so i'm getting a high flow water pump, and high flow water pump. heavy duty radiator and a 180 degree thermostat, dynomax turbo exhaust system, with that system do i neeed to buy a cat. converter???, and would an aftermarket throttle body help pull more power with the k+n intake and jba header???, the motor has 130k on it should i rebuild it before the turbo??
thank you for any input and advice, also does anyone know of any street suspension parts for them??

 

I'll be the first to say that turboing a 130,000 mile 4.0 is asking for trouble and I'd never do or recommend it to anyone.

that being said, if you are going to go turbo here's my advice:
Do a full rebuild on the block with stronger than stock parts would be a smart idea, but if you're gonna go to all that trouble just build a stroker motor.
High flow water and oil pumps are a good idea. The 180 Thermostat should work fine, go with a 3 row radiator if you're going to the trouble of replacing it. If the Dynomax system is a Catback exhaust then no, you don't need to buy a new cat.
I've never heard of, nor do I know of any companies who make street suspension parts for them. There's just not enough of a market.
