Can I swap a IC' compressor housing and wheel onto a NonIC' baby H1C without swapping the backplate? my friend wants to do this so he will have 4 inch flange on the housing so he can build his intake without having to get a reducer 4in-3in to fit onto the turbo

 

The way to tell is to measure the diameter of the wheel at the backing plate. If that is the same and it is the "band" style housing I would say yes your good to go. I don't know the measurements but if you check out Holset web site they might have the wheel dimensions on there.

 

I dont think you can. I tried it before and it dont work without the pin wheel rubbing,

 

I am pretty sure it will work. GDS told me there is only one backing plate with the v-band. The really small ag H1C's had a bolt on comp cover.

I just put a GDS on a baby H1C, I have one in my '93 too.

 

yes you can, done it.
but if his truck has fuel mods and a small exhaust housing with a 5speed i do not recommend it, on my truck i had really bad surge running a 14cm housing.

 

alright thanks his truck has got the 18.5cm2 housing and its auto so i will swap the IC compressor wheel and Housing onto the NIC baby H1C thats great thanks

 

what are you going to do about the compressor outlet?

 

Aint they the same I thought they were at least

 

baby h1c non i/c'd has a 2 inch strait hose outlet where as a i'c'd truck has a 2.5 inch v band out let that normally connects to a 90* elbow

 

oh thats right forgot about it so how did you connect them

 

i made a cross over and v-band to strait adapter, then i just went intercooler
