If space is cramped, and it sounds like it is.
Then the more efficient the radiator is the better off you will be.
Do some research of radiator construction and it cooling capability, then pick a efficient radiator, that fit your space.

You say other like yours don't have a heating problem, HP= Heat! Turbos are creating heat from power as well as under hood heat.
I see you have a nice open hole in the hood. that's a plus.
Is your air filter getting cool air or is it inhaling hot air from under the hood.

Ign timing could also be a factor.
Remember, cruising down the highway, your not using up all you HP.
Sand suck HP out of your motor all day long. takes HP to have fun in it. Radiator has to match.

Very good points!!!!

I had this issue before I went turbo....however I do make more power now so the issue is the same or worse.

I found a nice griffen radiator on their web site that I could probably make fit. I just don't want to ruin the factory grill look.....but I could get pretty crafty and make something work. I after all have a CNC plasma cutter in my garage lol.

That was for a hood scoop that did not work as planned. I plan to replace the hood at some point. I did have hood louvers on it to let heat out.

The turbo does suck hot air in. I do have a water injection to cool the intake as there is NO room for an intercooler. I get my intake temps down to about 110* at 7-8 psi. Ignition timming could be an issue. I do need to work the table. May not solve the issue, but it definitely will help!

As of rite now, I'm going to install a bigger radiator....it won't hurt! I'll probably weld some AN bungs on it as well so I don't have to cobble two upper hoses together creating a bottle neck of sorts.
