hey guys, i know that ASP makes the intercoolers for the rx7 store and M2. ive run into a dilema. i saw that the large now advertised on the rx7 store comments that the battery will not need to be relocated. i went to M2's site and they claim that the battery will need to be relocated. whats the deal with this??? i have a 51r in there anyways, but dont really want to go down to a hawker if possible. if that is my only choice then i will. just thought i would give a heads up and see if it can be answered before i go into the purchasing portion for the intercooler. thanks a lot guys

This may depend on what type intake you're running. With the M2 cf intake and the large ic, I had to move my Hawker Odyssey to the rear. With the medium I had lots of room. Have no direct experience, but was told that with some of the other intakes, you can move the large ic over enough to fit a battery in the original location.

Here's a picture of my car back when I had an ASP large IC (and a rotary engine)...



As you can see, there's not much room on the intake side, and in the picture below, you can see how little room is left on the battery side. If you're concerned, get the medium IC. It works every bit as well and will allow you to keep the battery up front, although you may have to get a smaller one.

In comparison, here's a picture of a friend's car with the ASP medium IC and a stock battery...

what kind of block off plate is that next to the intake? custom?

SCC didn't notice much gain/loss between the two... if you want to keep the battery in the stock location, the medium is still a great intercooler.

It's part of the Pettit cold air intake.

Although it's not suggested some people have managed to use the large with a smaller battery in place up front. It involves shifting the IC over to the passenger side more than normal if the intake system allows for it. It results in some part of the core not being in the airstream of the duct.

If you want to keep your battery up front I'd suggest buying the ASP Medium, it's designed to be used even with the stock battery and is close to the same performance of the large. That's the reason I designed the two of them, each was designed to do the best possible job depending on if you wanted to move the battery or not.

If nothing else your timing is good, the group buy will be taking place shortly which will save you some money. I have a couple minor details to work out on it and have to figure out how RX7 Store wants to handle it.

Jim really answered all this already. Thanks for the help Jim.

Kevin is describing my set-up

Bigger is always better. Just something about a large IC dominating the engine bay that gives me a warm feeling in my loins. Also, it gives one an excuse to move the battery for increased longetivity.

I would move the battery into the bin or trunk just because they last 5 times as long being in a cooler environment.

With the battery in the engine compartment, I had to replace the battery every year. The heat just killed it.

Moving it into the trunk I haven't had to replace the battery in like 4 years now even though the battery is smaller.

kevin, is there an efficiency range of the two intercoolers that you could share with us. im looking at a GT35/40(aspec) and possibly their new GT40BB and would like to know if the turbo would over kill the intercooler. i remember reading about ???silver ninety three???i think, that had the greddy front mount and gt35/40. he turned up his boost to about 20 lbs or so and made nice numbers. i dont want the medium to be a bottle neck. how are these designed for efficiency that high. i want to stay away from the FMIC if possible. im also using a koyo. any news on fitment issues.
lastly, get a good battery and you will not have to worry about replacing it every few yeras. i had a duralast gold from autozone and it is the best damn bettery i ever used. i then switched to a 51R duralast gold and it works like a champ still. two years strong and counting. i used to work at autozone just thought id throw that in

I'll respond in greater detail later but for now I'll just say there's no way you're going to exceed the capacity of either IC. If you were running 30psi you might start to see a slight ramp up in pressure drop, but 20-25 won't be getting close. We're using essentially the same IC on a twin turbo Buick stage motor that's around 1100hp @ high 20's psi. The Stock Mount will be even more of an improvement over Front Mounts the higher you raise the boost simply because the reduction in tubing volume that you have to pressurize to that even higher boost level. Simply put the higher the psi the worse a front mount as strange as it seems. The best way to put it is raising the psi will exagerate any shortcomings.

very nice. just what i wanted to hear and directly from the source. i dont see much of a reason why i would want a complicated front mount. ill add a fan to the intercooler like maxcooper did and hope that helps some

My old setup, FTL intake with ASP Large.

Kevin T. Wyum

Okay, confirmed what I needed to on the group buy thing and talked to Jason at the Rx7 Store and it will all be going through them as normal. It's a $200 reduction in price if the minimum of 10 orders of either medium or large is met. There might be an additional discount if it exceeds 20 (very iffy). This is the only time I have any plans for doing this kind of deal so keep that in mind if you're not sure.

With that I'll turn it over to Jason to handle.

Mr. Stock

Is the large intercooler the revised version which does not touch the hood? Or is it the original version of the ASP Race intercooler?

Kevin T. Wyum

You might be thinking of an old version from about 4 or 5 years ago that had one corner of a weld on an end tank that would touch a hood support during engine flex. There's no cutting the frame, bumper, moving power steering, AC, radiator yadda yadda. It's a straight 1 hour bolt in.

So I guess the answer is yes it is.
