13 Row oil cooler big enough for 325i?

[Turbo-Brown]

Does anybody know if a 13row oil cooler would be big enough for my modded 325i engine?

I've put a pair of intercoolers where the original one lived so I can't really use that now

Cheers!

How many rows does the original BMW oil cooler have? Ive never bothered looking.

I know mine is missing the 2 turbos that you got, but Im using the M20 cooler on my S50 conversion.

And where you thinking of mounting it, if the intercoolers are in the way?

[Turbo-Brown]

Think it's 5 or 6 rows, but the BMW one seems to work in a different way to aftermarket ones in that it's miles long, but doesn't have many rows.

Apparently the 13row one has a 97x230mm core which sounds nice and big

Gonna stuff it in beneath the panel that's under the offside headlight I think. It's well protected and some scooping should get the air flow up.

you dont want to cool the oil too much or it wont do its job properly

[Brianmoooore]

Only way to tell is to fit an oil temp gauge and see what max temp the oil reaches.
Oils have come a long way since the E30 325 was designed, and I doubt if a cooler is really needed on any unmodded 325, but with a turbo the only way is to measure and see.

a 13 row oil cooler should do the job as my bro in law had a 13 row on his 300+ bhp nissan 200sx s13

If you get a decent one it'll have a thermostat anyway.. Ie it wont cool the oil until it reaches a pre-determined temperature. This helps the warm up of the oil and stops it overcooling.

As for whether its big enough (will it cool enough)... Dunno mate . The oil's gonna take a battering with 2 turbos. Perhaps just change it every 3-4000 miles and don't worry about it.

the stat for the oil cooler is on the housing anyways so no need to budget for that Alex, as for the stock unit, mines upside down @ an angle accross the rear of my IC, its a squeeze butcan be persuaded to fit, if you find the hosing clashing you can cut and shut the steel sections @ the block end to improove the situation

[Turbo-Brown]

The problem I've made for myself is that the front turbo is too close to the block to allow the fitment of the old plate

Know what you mean about the over cooling though, will have to get a stat too

Remote filter and stat setup seems the way forward then dude ?? will add a few extra litres capacity too which could be useful
