I have a greddy turbo kit and custom intercooler, what i need is couplings with a whole bunch of odd sizes like 2.75 to 2.5 or 2 to 2.5 and random stuff like that.. i looked at Ace Hardware, AutoZone, Kragens, Pep boys, Home Depot and none of them have the odd sizes, where is a good place to get them?

ALso, I'm about to buy RC 370CC Injectors, do I have to replace the seals and insulators? thanks

 

For the injectors you will have to replace the o-rings and the harnesses if your car is 96+. That requires cutting the OBDII harnesses out and soldering the supplied harnesses in.

For the couplings, I couldn't tell you. I would think that any home improvement store like Home Depot would have silicon tubing that you can use for the couplings. :dunno:

 

I don't know much about custom intercoolers and what not but you might be able to find your couplings here. This place seems to have everything. Let me know how everything goes.

Any procedure for the Greddy 18g harness stuff if my car is a 95? Replace the O rings?

 

I don't think you need to swap the harnesses on an OBD1 car since the harnesses are already OBD1. The O-rings need to be replaced but they should come with the injectors unless you get them used.
