looking for input on what intercooler I should get for my twin turbo project that I will be working on over this summer/winter.I will most likely be getting garrett g18's set up. My other question is I have a de motor so should I look for a twin inlet signal outlet or can I go with dual inlet and dual outlet and size 2.5 vs 3 inch pipe.

 

is it a custom setup. an twin in single out

 

after seeing your other post. just buy a used kit of here. it looks like u have plenty of time to wait for a good kit to come up for sale.

 

dual in / single outlet...

Its my opinion that a IC that feeds from the bottom and outputs from the top would be best ... as compared to a left feed right output style...others may disagree

 

Its kind of a custom set up for the most part I'm copying the garret twin set up.The place that Ive been working with is a local garret distributor,Ijust don't want to spend the money on the bolt on kit.He is also the only Uprev dealer/tuner in the state.They have not done any twins in a 350 yet,they did a twin in a 370 and got 450rwhp with a turbonetics kit and a meth inj setup.Not very impressive at all !! I'll be building the motor over the summer as long as getting parts for this build,I'm HOPEING to get 500-525rwhp but would be happy in the 470-500 range . Most of the machine work I will do myself (boring the block,making the spacer for the oil pan and the intake and possibly the injector rails to).We have discussed every thing but the intercooler ,or I should say they are only interested in selling me one for around $1500 . I'm not ready to spend that on a cooler just yet

 

I have always had great results with treadstone intercoolers. They are great priced and work well. It's what BP kits come with.

I actually have a polished treadstone intercooler with custom brackets for a 350z/g35. It's 3" in 3" out vertical flow. I was using it up to the 600hp range but switched to a larger one when I started pushing way past that. I used it for maybe 8 months. I haven't really been trying to sell it but it's collecting dust so I would make a good deal on it. PM me if you are interested. If not then I suggest looking at vertical flow treadstone intercoolers online.
