I want to use a large frame single(gt4788), but I really have a problem with hacking my radiator support to run a large single.

Is there anyone out there that has been able to run a front mount large frame turbo on our cars without cutting up the radiator support? I dont mind doing a little notching to clear the radiator cap.

i would really like to see pics if anyone has been able to do this.


Thanks

I left the top of my support, but cut out the bottom and made a smaller radiator support. There are some pics in this thread.

To fit the 4788 you will have to cut the support. Really no way around it. Whats the big deal cutting it?

Just cut it, they sell the support for like 200 bucks, its not like you CANT put the car back to stock later...

where can you buy the radiator support?

ebay or from GM directly.

If a car gets hit in the front and damages the radiator support, where else do ya get one?

I just didnt want to hack the car up. I dont really have any illusions that my car will be worth a fortune one day, but I just wanted to keep from cutting too much.

Copy. Yeah unfortunately with this turbos size you are left with cutting the support. Atleast you know that there is an option available should you decided to return the car to stock form.

What are you running for a motor?

404/ PI 6-bolt 235 is what I am going to run........I have the short block, but not the heads yet. It is just a ls2 block, but that should get me by until i am ready for a ERL or RHS block.


I don't know why i am so against cutting..........im riding on a spool with no A/C.


I just thought maybe someone had thought of something that I was overlooking.


I may be better off running twins................they should be easier to fit if I move the fuse boxes.

i am in the same book as you. I have the same year and color hawk as well lol. But i am not running a big frame turbo, but it's positioning and the aftermarket radiator, make cutting the support almost a guarantee thing. And i was thinking the same as you, don't really want to cut it lol.

Yeah if i had a mustang i wouldn't hesitate cutting the crap out of it......lol

^^^ you can make custom headers and try to make it fit in the battery area

cutting the top rad support is not that big of a deal, i cut mine and welded it up nicely and most people can not even tell i have cut the support. and then you have all the room you need, even for twins.

also i would advise against fitting a smaller radiator that fits without cutting the top or bottom rad support on a street car. lets face it, a turbo car is going to make allot of power, and that will create some serious heat, so try to fit as big of a radiator as you can

I really may have to deal with notching it a little bit. I'm going to get all of the piping ceramic coated and run the exhaust wrap and turbo blankets, but I will still need a substantial radiator and fan setup.

elias 799, do you have any pics of how you did yours?


I just see a lot of people cutting that whole section out and welding a peice of square tube to the front...............I really don't like that as much........I would like to leave at least half of the factory suppport.

depends on how creative you want to get. I cut out the lower support on my old build and left the upper...radiator was moved the front side (used the griffin rad everyone else used). Turbo shown is a GT47

Like you said you already have a spool and no AC, you have to do what you have to do.

You are correct....................I'm not building it to enter into the Factory class at a car show
