Im building a zetec turbo mk3 fiesta track car- omex ecu, focus rs t25 turbo and manifold ect, approx 280 - 300bhp

Do i need an ally rad or will the standard xr2i 16v rad be ok?

Do i need to fit an oil cooler?

 

I would upgrade both for track use.

 

I was firing forcing 2bar down a gt3071r and a standard xr2 rad was fine with a 19 row mocal for oil.
A bigger ally won't do any harm though, good fan is essential more than anything.

 

Thanks for the replies.

Il get the 19 row Mocal oil cooler kit.

Il also get an ally rad.

On my last one i had twin fans on the front of the front mount intercooler, but this time im using a 2wd cossie front mount intercooler- its wide and deep, but not tall enough for fans on the front...

Any idea what (pull) fan i can use behind the rad (where standard one goes) ??

 

astra turbo diesel

 

What year roughley?

 

Id say yes as your car will generate ALOT more heat on track than on road

 

96-2000

 

depends how you drive....
more than likely the case though.
the 2wd cooler isn't the best choice, even a universal one would probably be better if it has a lot more rows, that way you can use a front mounted fan, i got away with an erst one, slightly modified to make it a little narrower but just as effective.
all depends on what you have to work with in regards to space and funds.

 

Ive never got my cars on the road near the temps I had on track.

 

i used a pace fiesta turbo alloy rad with modified bottom pipe to meet the fiesta zetec hose
this was mounted tight up to the slam panel the i used a pro alloy large front mount intercooler which was mounted low down so you had good air flow to at least about 35% of the rad and i also used a 12 inch kenlowe fan kit slimline and mounted it between the intercooler and rad. worked a treat never overheated and if i gave it a good thrashing or was stuck in traffic i could simple adjust the fan controller to come in at a lower temp
most cars ive ever seen overheating are not on track its when they are stuck in traffic when no air is being force in to the rad.

hope this helps
