Intercooler dilemna... what to do?
The intercooler I bought off eBay is turning out to be a slight pain. The inlet/outlet are 2" diameter... and that seems to be a difficult size to come by in a kit.
The inlet to the throttle body is 2.5"
The compressor outlet on most T25's are 2"
Bigger piping is better than smaller piping for flow (to a degree). 2.5" piping is not a problem to run through the spaces allowed.
Nobody makes a 2" kit on ebay.
So, what I'm thinking about doing is just getting rid of the intercooler I've got now and buying one of the 2.5" ebay kits that come with the black piping that I love and include an intercooler. They go for about $150 shipped. The only other thing I'd need would be a 2.5-2" reducer for the compressor outlet.
I can piece together a complete 2" pipe/coupler kit but it's going to cost me the same as simply buying a 2.5" kit that comes with an intercooler. Then I can resell the current one to recover costs.
But I'm still going to wait until the turbo gets here and I can put it on and see exactly what I need. Then I'll buy the kit (or parts) and change the clutch while I'm waiting for the parts to ship. The new turbo shipped from PA yesterday... should be here tomorrow. DP should be here today.
I also think the compressor inlet is a 2" piece, but the MAF is a 3"... so I need a reducer coupler there and a length of 3" pipe or a 180* bend or something... again, figure it out when it's up on jacks and I can lay everything out and measure.
