I used to use powers service fuel supplement in my 93 with excellent results, i could tell when it was in the tank by fuel milage and the way the engine responded in my 91 there is no difference. Any suggestions?

 

Power service silver bottle. You feel it less because the 93 has 18cm turbo but 91 has slower spooling 21cm exhaust housing.

 

Know that, anyway to swap them over pretty cheap?

So in other words i can't take the turbo off my wrecked 93 and make it work on my 91

 

I think it's a straight swap provided your '91 has an IC and the airbox may be diffrent. I thought you were wanting to make your '91 turbo like the '93 turbo.

 

No sir I wrecked the 93 and I picked the 91 up for 1200 bucks. The 91 ran and is in fairly decient shape, the motor runs great but knew it had transmission problems. I took the tranny out of my wrecked one a put in it. I used to b a diesel mechanic so i know how to diagnose things a fix them just dont know much on upgrades. The 91 is non intercooled but I am told that it is not a major undertaking to make it ic. Just wondering if i can take the intercooler and turbo off the 93 and put on the 91 and if there is anything else I need to swap when doing so.

 

There are two ways to do it. If your 93 radiator, radiator support, and intercooler are good. Swap them over to the 91 along with the turbo and all the tubing and air horn.
Otherwise, you can use a 2nd gen intercooler with your 91 radiator and support instead.

 

Alrighty thanks. I hot a cow in the 93 I'm not abad driver it was either the cow or trees. I know the radiator is no good is there a way to check the intercooler before installation.

 

I'm sure you could rig up something with stuff from these guys since it's done all the time, you just need to know the specific measurements.
