Default A2W or A2A for ls1 turbo street car?

Doing an RX7 LS1 turbo setup. t76, forged 347, t56, looking for 700rwhp.

I have been looking at a FMIC A2A setup, i can fit something probably 29-31x12x3 maybe 4 thick. Here are some pics of a similar intercooler:



I'm just wondering if I'm going to have any heating issues with the radiator with that big thing in front. I am unsure if I will, I think I can feed the radiator from the bottom possibly, and I have a fan from a Taurus that moves a TON of air.

A friend said that I should look at A2W and I had always dismissed him because people said they weren't good for the street. I did some searching and looks like maybe if you have a large heat exchanger they work well and keep the temp a little above ambient. What size A2W core is needed for 700rwhp?

The A2W is going to be more expensive, so I don't know if it will be worth it. Should I try out a FMIC first? Any ideas help!

just do the A2A, if you can seal the area between the IC and the radiator, with an electric fan it will work just fine. Plus its way cheaper, and much easier.

Best for street, especially if you like road-race type driving, or numerous WOT pulls.
