Hi peeps just wondering what sized intercooler (number of rows) do you recommend for using on a zetec turbo engine that will be revving upto about 7500-8000rpm?

thanx for your help!

simple the biggest you can get in

lol fair enough....i am also relocating the oil filter...does this mean in conjunction with the cooler, i will require ALOT more oil than the 4.2litre it will normally take?

Go for a 13 row cooler IMO, will do the job on that engine and won't take up too much space...

will need a fair bit more, as the oil cooler will be full of oil too.

however, the idea is to keep the Oil at Around 80 Degrees or just above,
as this is considered working temp for oils in an engine

fit too big an oil cooler and it may over cool the oil, and this can lead to
problems in itself
unless you get it set up with a thermo-sandwhich plate, so the oil cooler
is only used when the oil is hot enough to need cooling

What oil temps are you currently seeing? Where do you intend to use it?

Road and track are hugely different re: oil temps.....

bassboy

in all honestly the engine is not in the car....and the car will be used daily...the thermo plate is what i was considering using (anyone know if they are worthwhile for road and occasional track use?)

however when the car is on track...it will be used to its full and will be taking part on PLENTY of top speed runs

regarding space...ill need to have a measure up of where i can mount it, but wherever it is will have optimum air flow...either in direct air or with a scoop

i'd leave it until you know you have a problem with the oil temps,
if you do, then its only gonna cost you an afternoon of testing.

bassboy

quite a number of people have suffered with problems with oil cooling on zetec turbos as there is no cooling for the oil when putting the engine in an escort mk4...so i just thought i would stay one step ahead and add one before i do have any issues

ah right!
im sure one of the guys that have done a zetec turbo will be along soon to help!

bassboy

im sure ive read somewhere that according to the amount of extra RPM you are going to be hitting, the bigger the cooler be...but i cant remember where i saw it lol
