3SGTE: eBay IC cores: for low power only

[kercha83]

so to get a heat exchanger i could just use a small radiator or oil cooler for one. And where would the heat exchanger go, before the water enters the intercooler or after. And would i need a fan too.

is the resevoir in the engine bay? if so your just pumping hot water into an already hot IC. Sang is correct, i'd take a A2A vs. a w2A with no heat exhanger. Mopwer made a very nice setup that uses the stock turbo IC as a heat exchanger, you should hit him up for a nice DIY setup. I saw it in person and i very empressed . gave me some idea's.

you can put a small core in the same stock IC location and put a nice 9-10" puller fan on it and it would be pretty effecient. i was thinking of running a small thin radiator like core up in the front of the car in front of the radiator to make a sort of FMIC affect. that way i wouldn't need a fan, the water lines, water, and heat exchanger might add a lot of weight though. One other good spot is under the motor near the trunk area, or in the trunk if you don't mind.

what turbo was on car for those dyno and temp sheets?
improper a2w IC kit will climb in temp, however
enough water capicity, like running your radiator all the way up front,
maybe incorperate some sort of thermostat type thing the in system.
and maybe some sortof refridgerent gizmo in your resivior.
or a electric cooler thats for gasoline, ive seen this in summit catelog for drag cars.
cant find the damn part #. im looking.. stumbled across that few years ago.

probably still use a2a enigine bay though
just cant figure out shoud i ram air onto IC like (porsche or subaru) w/scoops
or run tubes from the vent to fans straped to the bottom of IC.
seperating and isolating air from vents to the IC.
the natural vacuum of air passing over car will help suck air threw and heat away frm IC
the IC will be angled different for each app.
a custom engine lid will be for each also.
input on any of these idea's would be cool..

RICKY! HELP! URGENT!

I have a sw20 3sgte, it has been modified quite heavily. I just recently installed a gt3040 turbocharger. I am using a Greddy side mount.

At 18psi, the car made a little under 190rwkw. There is a serious problem here because at that boost level with this particular turbo ALL mr2's that i have heard of with the same setup made 250rwkw++ at 18psi. Air-Fuel ratios are perfect aswell. My CT26 at 16psi made the same power..

WHY is a turbo thats twice as big as my old one, running more PSI then my old one, giving me the same power as my old one?! All my mechanics say is that "your intercooler is too small, it cant handle the flow". But im sorry people have made well over 200rwkw with this intercooler. Yes its not recommended but it is very possible. The turbo is spinning at 18psi, my ECU is practically saying on the laptop "this is easy" but im just not making the power.. please help. someone, anyone, HELP!

Cheers

stock intercooler can make over 300whp with 46trim t3,4
so thats not it. has the intake manifold ever been off?
what did you do with your timing on the ecu?
were did you get turbo?
if not new how old is it?
when the turbo was off the car how easy was to spin the wheel?

So what ebay IC are being used anyway? I'm looking for another solution after being told my IC is to small :o(

Go w/ meth/water injection for a cheap, easy setup. I plan to go w/ water injection which should suffice on my ~325rwhp build w/ a KO Intercooler (uses ebay core)

what do those run right now as for price for a basic meth injec kit for a 320bhp set up with ebay side mount IC?

If your planning on less than 325whp stay with the stock I.C. and put meth on it. Others here have made over 350rwhp on a stock I.C.

The stock IC has a pretty large pressure drop across it. I'd upgrade it anyway.

[Luni]

Kens right. All things being equal you will experience less pressure drop across an aftermarket IC vs the stock one. That means your turbo doesnt have to work as hard to get your air to your throttlebody.

Yes, but the misconception perpetuated by the community is that the stock intercooler is done by 250whp. Not so. On a stock turbo (ct26 or ct20b) I would not bother to replace the stock I.C.. The ct20b will put you in the low 300 mark quite easily.

umm... i don't think you know who your talking to .

i've seen a japanese article on a 500+whp mr2 running a stock intercooler. sorry but i can't translate the article, but with a huge turbo, motor upgrades, and enough boost anything is possible. Luni's nearly pointing out the simple fact that for reliable safe easy power, an IC upgrade is well worth the small investment as far as functionality. Correct me if i'm wrong Luni.

I have an upgraded CT-26, and plan on going from 8.5 psi to around 17-18 on race gas, and with a lower pressure drop, a larger core, and a larger fan on my upgraded SMIC, it will help keep temps down better, and flow easier than the stock unit. my goals on the stock engine, ct-26 and bolts ons is in the 315-325 bhp. my only debate is adding meth/water injection to help cool the charged air at around 9-10 psi, having the kit kick in around there that way im not always shooting the system during easy driving.

I never said the other one is going to provide a whole lot of heat soak protection over the stocker, the fact is, it provides less pressure loss, which equates to more PSI to your engine, and less work for your turbo to attain that PSI.

Its a VE mod. Thats pretty much it.

agreed, with my setup, i can feel the turbo spoil fast and the engine is responding to it very well after the upgrade from the stock IC. and at only 9psi to!! when the i first got the car, i could tell at 14-15psi with the stock IC it wasn't running as well as it could be. course, i had 2 blown piston ringlands too
