I was reading an article about intercoolers and their flow/cooling capacity and how they affect the throttle and engineresponse due to their loss in pressure.
So is the intercooler in the kit designed and choosed from the default map GReddy provided with the kit or is it choosed to support the turbo 100%?
The intercooler may be undersized and not cool the air enough after doing more changes to the car to increase performance and boost?

The only way to answer for sure is to measure the pressure drop and temperature differential across the Intercooler referenced to ambient temp. Wouldn't be that hard to do.

The Greddy intercooler was probably designed with the intention of it working good with their kit in the setup and power level that they intend the kit to work at. It is very possible that turning up the boost could heat it up too fast. It is also possible that it isn't a good sized unit for a larger turbo. Basically it was all designed to work together as a kit at a certain power level.

The intercooler that comes with the greddy kit is sized fine. It's actually quite large for the boost pressure the kit provides. I'm not sure of the numbers, but if someone knows please post :p

I heard through the grapevine of a guy who swapped for a larger IC, and lost power due to greater pressure drop...can't vouch for the accuracy though

hmm that would be intresting since its one of the 1st things I want to play around with.

I think the intercooler is pretty solid. Mazsport has some interesting modifications coming out for the greddy kit. I would recommend looking into that if you want to make some serious gains.

Very interesting!

Yeah, so was the E-Manage with their initial settings. We know how that goes ;)

there is a huge difference between a Fuel Management System and an intercooler.

WORD!
Anyone thought of measuring the airtemperature at the inlet and outlet of the intercooler to measure its coolingefficiency at different boostsettings. I might consider that.

No shit genious. IMO Greedy did a shitty job in putting this turbo kit together. I think they rushed it. but for the amount of CFM and boost that is intended for. I do think it is a good size.

BTW no offence meant by my comment.

Isn't the Greddy kit based on a Japanese Company's kit for Japan. So the Greddy kit is just a US verison of a Japanese kit. I don't remember the company tho :/

Hey , let's not forget Greddy is the first turbo out there.. There is always room for improvement.. But for what it is , it's still a damn good first try.. I'am putting out 284whp with the Greddy turbo at 9psi, and I'am not done yet and I don't have any issues. Other then I want more power...

Nope. It's 100% GReddy. RE Amemiya did work with GReddy on adpating it to an auto transmission car though.

you may be confusing it with Trust, which is greddy's japanese parent company (although the greddy brand coexists with trust overseas)

6 of one, half dozen of another. Trust is the parent. Some products are released as Trust and some as GReddy in JDM. Either way my point was the the kit was NOT made by some Japanese tuning shop, but by Trust/GReddy.

No shit genious. You're original comment was based on the reasoning that since the emanage was not sufficient for increased power, nor would be the intercooler. You seem to be basing this on the assumption that the entire kit is insufficient.
The fact of the matter is, you do not know if the intercooler is sufficient or not. You seem to be very angry at Trust/Greddy for making this kit... which is fine, but you shouldn't make youself look so ignorant by making stupid statements like...

ANYWAY, back to the original question at hand. Untill there is hard data from testing (like what Petrus suggested), i wouldn't rush to throw on a bigger intercooler.
If your intercooler is sufficient, and you replace it with a bigger one... all you're going to do is decrease the airflow to your radiator and not receive any benefit in return.

If you are happy with spending $3k and on what ever it is and it not working properly then you can give me your money I put it to better use and you don't have to worry about blowing your motor.

Now if I was going to be mad at some one it would be Mazda for creating a under-powered great handling/looking car with a complex electronic system, not Greddy. The E-manage works fine in every other cars. I just think they rushed it on this car because we know it can work way better than it does out of the box.

The emanage can actually work out quite well on the rotary. A couple of guys here have figured out how. The way it comes from Greddy isn't the best way to hook it up though. They rushed it to market and that is what suffered. With a few fairly easy changes it can be quite nice.

Yes it took me all of 4 minutes to execute the wiring changes,and about 30 minutes to relocate the signal nipple for the the wastegate.Yesterday my car started on the first turn of the switch,perfect idle and no CELs.Power developement to proceed with deliberate care.

This is my point. You have to pretty much trash the instruction that comes with them and firgure it out yourself.

Make sure you have the MAP for the 390cc injectors loaded - if you haven't upgraded them yet. Its in the other thread but I can send it to you if you need me to. Also, I've found that as I pushed higher above 6kRPM (by adjusting the wastegate actuator) that I needed to retard the timing. The need only arose after going above 7psi and 6kRPM. But, rigging the eManage timing controls is easy. Takes less than an hour.

So have you actally installed oe of these kits,or are your comments based on 2nd hand information?

Have you read the info on this forum?
