hello guys,i need a new intercooler for my cosworth as its for a escort cosworth which i have on now and the boost pipes are not lining up proply,ive seen some rs500 style 1s on ebay but some have 76mm inlet and outlet and some 1s with 60mm inlet and outlet,also will i need diffrent size boost pipes with my car having a t34 turbo,cheers lads and sorry if this has been asked before.
cheers

 

go for an airtec, bolt-on with no issues, cheap and performes very well. you need a slightly bigger inlet hose between filter and turbo.

 

As above airtec RS500 are excellent value for money and work well into the bargain, the outlet from the intercooler could be better aligned, but can be used without adaption, just if airtec gave a shit and moved it a few mm, fit would be 100%, but they don't seem that bothered.

nice 1 cheers lads.what about these intercoolers on ebay

will this be any good.cheers

 

Airtec

 

The cooler in the link will do the job, if not going mental power wise would be fine, though the design of the supports doesn't look good where it bolts to the chassis.

thanks for the reply again mate,power wise am hoping for arounf 350 bhp with a t34.63, 3 bar, msd stage 3 chip,siemens injectors,low comp pistons,would the intercooler in the link be enough for my power estimate,
cheers

 

Intercooler will be plenty good enough, to go with your very odd spec engine!!
if wanting 350 keep the std compression, and the std .48 housing.
No point imo making it laggy with lower cr and bigger turbine, a t34.48 will happily do 350 all day long.
Up to you what chip you use, but there are others, I much prefer GGR, a few basic things to check and off you go.

cheers mate that will do for me,do you no where i could get a boost hose to fit the 76mm outlet pipe,ive searched and only 60mm come up?
thankyou again

 

Most of the major silicone hose makers should be able to supply one, just have a look on websites for RS500 hose.

Roose hoses will make you almost any size you want for a very good price.

He just made me a custom inlet hose, 63mm intercooler to 70mm TB
