intercooling 2.8 gq

[Joshie87]

will a gu 2.8 intercooler fit onto a gq 2.8 with not too much trouble?

the GQ and GU RD28T engines are the same so the intercooler will fit however you will need to use all the pipework fromt he turbo to the IC and the IC to the Inlet Manifold from the GU unless you want to make your own custom ones.

You will have to support the weight of the intercooler also. On the GU's they use a tubular frame running from the firewall to the radiator support panel for the intercooler to mount on. It's pretty intricate but it works well, I don't know if you can retro fit the same frame to suit the GQ.

would also need an intake manifold from a GU as it has the intake hole at the top instead of underneath like on the GQs. Would make job loads easier anyway. Ive just done a front mount on my 2.8 GQ it wasnt too hard and works great.

thanks for the info guys, I'm not too sure if I wanna put a top mount on or a front mount! Which is better/eayser?

Both have their advantages and disadvantages

Front Mount

Advantages: you can use an IC as large as the front of your car giving you the ability to cool alot more air. Cooler air at the front of the car meaning your getting alot more fresh air to the IC

Disadvantages: The mount of piping you need to run from Turbo to IC and then IC back to turbo means you get more lag then a Top Mount. Front Mount blocks the radiator more, and puts more heat into the engine bay, if your engine runs a little warm as standard, it will run bit hotter as there is more air restriction and hot air being forced into radiator

Top Mount

Advantage: Less pipe work between Turbo to IC and back to Manifold, reduces turbo lag. Top mounts keep the turbo away from the radiator and help keep the engine cooler. Bonnet scoop helps keep the IC cool with air

Disadvantages: Smaller IC, you can't cool as much air with a top mount as you can with an Front Mount, so high boost engines won't cool as well. If you have a high mount Turbo your bit hard pressed to install a top mount as there is little to no room to do it

I've got a 96 gq 2.8turbo RX, running 33s, I don't wanna push heaps of boost through it or anything I just wanna help it out a bit.
And I thought a top mount off a gu would be an easy fix!
