Water to Air Intercooler on 4AGZE

[TC1600]

I remember Neal Bates homologating an a2a intercooler (from w2a) on the Group N/P Corolla, for probably much the same reason as Terra stated, as well as the weight reduction factor. So for outright competition on long stages, a2a would be the go, but for street applications, where you aren't putting out full boost for long periods, the water supply would have ample chance to cool, so would be unlikely to reach its saturation point. Plus they would be by far the best solution to the lack of space in an MR2 engine bay.

IMO more so the lack of good cool air flow to make a decent sized a2a work well enough like on the front of a vehicle. i would of stuck a2a if that were the case.

yes true, i guess what I was trying to say is there isn't enough room to position the IC in a good position regarding air flow (even if you could scoop it in somehow)

sorry to revise this topic. I noticed we also neglect one of the crucial part, total water capacity. What's the ideal tank capacity? Even with large HE, i reckon should the water tank too small, the water might not able to cool down efficiently. Pls correct me if im wrong

Water volume will determine how long until heat soak occurs. If you have a sufficiently sized radiator, it shouldn't heatsoak at all, but that would be a big radiator. A couple of liters should suffice for a 4AGZE under road use.
