Default 2.2t overheating

I put in a 2.2t out of a 93 ss leg into my 96 impreza brighton. I left the radiator from the 1.8 that was in it. Is it to small of a radiator? And no intercooler. I just bought one for it but I know they came stock without. Could it be that its in a super light car, I dont know. Any help would be nice. It just sitting in my garage because Im afraid to drive and screw something up.

mmm, i would suggest putting in a bigger radiator, i donno if the factory radiator from the leg would swap, but that would prob be your best bet. I know when i did my SR20DET swap in my nissan and used the factory 240sx radiator it would overheat in hot weather because it couldnt keep up.
start by taking it out on small runs and see how it does, just be careful.

Pull the radiator and clean it with HVAC AC condenser cleaner ( acid ) it will look something like this and you can get it at commercial HVAC-Heating supply stores $7.99-$11.99 a gal mix 50/50 with water and spray it on both sides with hand sprayer or pump sprayer wait 20-30 minets and thuroghly hose clean....its the stuff they used to clean your outside home AC unit for boo-koo $$$

Dont bother with anything that is "indoor use" or "no rinse". It will not be strong enough to cut through the road and bug grime. I have used it on numerous radiators, it restores them to like new in no time with no scrubbing. I will say this dont use it unless you pull the radiator....its powerful stuff and will cause corrosion on your car body-frame if not washed away with water....like if your battery blew up

B4 you go and buy a new thermostat pull your old one and drill 3-4 3/16" holes in it around the edge and put it back in. That will let water flow with out the thermostat opening and help keep temps down....if it does the trick get a lower temp thermostat 170-ish

The 2.2T engines have a very large capacity radiator. this is due to the fact that: they are turbo engines, and without the intercooler, it is a way to keep temps low.

I would try and retro fit the 2.2t radiator into the brighton. It should fit without any major modifications.

I would also consider adding ANY intercooler. That is one of the first mods for the SS crowd.
If your car does not have the hood scoop, then you can always go AWIC.

You'll need a larger radiator for sure. The one in my leggy turbo is quite bigger/thicker than the stock 1.8 one I'd highly doubt it could keep up with the demands.

Why is it illegal? That means if your motor goes, it's illegal to get another motor for it? Wouldn't it mean that junkyards selling motors would be illegal?

I don't see why it would be illegal at all. I have a swapped RS, my rs is obd2, so is my motor....

I doubt the radiator is too small. How do I know?

I swapped an 05 STI engine into a 98RS and used the radiator from a 93 FWD automatic Impreza. It is the thinnest radiator I have seen and the capacity is slightly reduced because of the transmission cooler inside.

My first vote is that your fans aren't working properly. Second would be the headgasket.

If you are racing/road coursing, maybe you need to swap, but I concur, stock radiator should do the job, it has for me on two builds.....
