Hi,

 

I'm Posting this on advice given, on another thread I started, that Andy at A&K Motorsport is the man in the know and am hoping that he can help.

 

I am in the process of fitting a radtec intercooler to my st 225 that I have now discovered is an RS intercooler with 2.5 inch outlets and am having dificulties with the cold side boost pipe see photograph

The 2 questions that I am looking for help with are:

  • Is this possible with the standard st radiator?
  • If it is not possible with the standard radiator will an RS radiator fit as a direct replacement and does this enable the fitting of the cold side boost pipe?

 

Any help or advice much appreciated.

Yes, you need a radiator from a very late MK2 ST or an RS. The outlet is different.

Or get an aftermarket one of the correct orientation.

:thumbsup: As Rob says it will be pretty hard to get it to fit with an early ST radiator as the water outlet is in the cway but you may be able to take the bolts out of the radiator cradle and move it along a bit then redrill the holes to give you more room. Easiest option though is to get an RS or late ST radiator or an Airtec alloy radiator. Here is what the Airtec website says about fitting an intercooler with RS sized outlets........

 

Important Note: The pre-facelift ST has a different radiator compared to the facelift & RS, this makes the left hand pipe (inlet side) very tight against the radiator cradle & boost hose, we recommend removing the radiator cradle bolt, levering the cradle to the right and re-drilling a new hole & then re-fitting the bolt. It’s very simple and easy to do, but is necessary to give you extra clearance for the bigger 2.5″ pipe, if you are still not happy with fit we would recommend fitting a RS radiator, not required to get the power you want, but makes cold side hose fit nicer.

I can't see you getting it to fit with the early radiator, the outlet is really in a bad orientation for the RS intercooler.

 

I would bite the bullet now and get a radiator rather than try to do something makeshift. If the frontal cooling is all done as late model the options are better.
