Default Can I stand the stock radiator up if I modify the core support?

I want to cut out the core support like many here have done to allow my radiator to stand more vertically and make more room between the motor and radiator and allow the use of stock fans, but can I do this with a radiator of stock dimensions? I want to keep the A/C, so basically what I want to do is cut out the core support and move the whole assembly forward keeping the stock lower radiator support. I am concerned that the radiator will be too tall when tilted up, and if I move the lower support down or forward I will be closing up what little gap I have between the FMIC and radiator (where the airdam forces air up to the radiator).

I need to know about this really fast, and any pics would be great!

im not going to say defenetly no but I had to get an aftermarket radiator for my set up. I think it's way too tall to stand up verticaly. Also the cap is ment for the radiator to be mounted at an angle.

So I'd need to lower the lower radiator support? I was afraid of that. I'd hate to bring it down, so dangerous. I just need more airflow and was trying to find a way to get the stock fans back in there. I want the A/C too. I think more fan is the only way to cool this thing, since it cools at highway speeds but gets too hot in stop and go driving.

I cut the cross member out and boxed the open ends with sheet metal. I ran a square tube across the boxed ends for support. Mine is tilted straight up, so it had to be lowered. I built a frame out of angle iron and set it lower to allow for hood clearance.

With that mod and relocating the battery to the back, it made plenty of room to mount my turbo.



*Edit - No ground clearance problems with the lowered radiator. The turbo hot pipes are much, much lower and rarely if ever scrape. No problems with the filler either. It's not a difficult job if you have a cutting tool and welder.

I saw your pics in another thread, but if I did it that way I'd have problems with the airdam being low and no room between the ic and radiator. Also I'd like to keep the hood latches.

Thanks for the pic though!

i say use a griffin 15.5x27.5x3 with 1 1/4'' plates then use one big fan with a ewp.... i will probably do this same thing this summer if it keeps getting the ECT hotter ....

You can still gain a lot of room by notching the cross member and tilting the radiator at a smaller angle. I experimented with that. You can fit a turbo right in front of the crank pulley by tilting a few degrees and going with pusher fans. I could still close the hood without lowering the radiator right up until almost vertical.

Yeah but I need alot more room because I want to try and reinstall my stock fans with my D1SC setup, but I don't think it'll happen.

I was going to try that too. Doesn't work because the radiator is actually to wide. Pulled all the way up until the sides hit, there still wasn't room for the stock fans.

I guess I need to find a better fan setup then. I am looking at the Zirgo fans or maybe adding a pusher.

It's a spal puller, I believe it's a 16" It seems to be doing a good job, I had it idling for at least 15 min and the temp stayed at 160. I need to drive it around a little before I can be sure.
