Looking to purchase my first 325 to get into the Spec E30 series, but was wondering if anyone had any input on which base car (325i or 325is) would be preferable? I understand the iS comes standard with LSD and closer gear ratios 1st-3rd...are these two features alone worth the extra price to find an is over an i?
not sure where you got the closer ratio box from, a 325iS has the gears further apart and 1 2 and 3 are all taller than a standard 325i box. They do have a shorter ratio LSD though, its a 3.91 instead of 3.73
@downhiller...do you still think it is worth the premium considering I will be swapping out the suspension for spec units anyway? and the lsd can be purchased separately?
Thanks for mentioning it :thumbup:
I want to retrofit one into my 323, as we think 100F is a balmy day :yikes:
The cooler is not the issue, but the adapter to the engine :dunno:
I do not want one of these generic adapters that flows oil through the cooler on start-up :thumbdwn:, but one that only starts flowing through the cooler upon a certain oil temperature being reached :thumbup:
Where can I get such ?
I suppose the pressure hose I need to plumb into the turbo later on, will come from the oil pressure switch ?

There are 2 gearbox part numbers allowed, and have the same ratio's. You have to run a 3.73 final drive, H&R Race springs and Bilstien Sport dampers. Any sway bars are allowed, but have to be attached to the control arms (no m3 style mounting), and have a limit on the amount of camber/caster you adjust. Strut bars are permitted as are electric fans, power steering delete, A/C delete. There's more, but not going to go into into it here, just read the rules...
All b25's came with oil coolers. The 325eS and 325iS came factory with sport seats, different lip or air dam, LSD final drive and trunk spoiler. No iS or eS in sedan formats.
Gasturbine, enter the last 7 numbers of your vin into realoem.com and you will see all the options our car came with. Being older cars, they often have swapped parts.

Ive been down this road before. Sites says nothing about sport seats, but first owner insists those were the original seats when he bought the car off the floor. :dunno:
Markseven, before you get me more confused than a baby in a topless bar
Code:
Those are notorious for being stuck open or closed. You may want to source a new one or an aftermarket unit.
Are talking bout the H2O Thermostat or one in the Oil-cooler adapter circuit ?
On the Oil cooler adapter, what are the possibilities ?
I have a 323 without a Oil cooler and am looking on how to adapt this oil system to such.
The cooler itself is not the issue, but how does one plumb it to the lubrication system. On the ETK it looks like it is part of the Oil filter housing assembly, but I cannot go deeper than that...

Hey man, sorry, I was mistaken, the thermo is not serviceable. You need to get the whole oil filter housing. IIRC, the cooler reduces temps by 4°, so it may not even be worth it... except for more oil capacity due to the cooler itself.
The story behind Oil coolers on high revving motors is that the oil temperature increases exponentially with RPM. I did a study for Toyota on underhood temperatures :bigpimp:
If I want to fit a Turbo...
Anybody got a part# for this oil filter housing with cooler connections ?
Will this fit on my 323 block ?

Thanks for the link Markseven :thumbup:
On my 323 the Filter is bolted directly onto the block.
So I am not sure whether the Oil filter head 11421711070 will just bolt on and voilá ?
Why would you think I need to relocate the filter with a Turbo set-up ?
Will it be in the way ?
I have not yet decided on where to purchase my Manifold and what Turbo to use, as I first want to see what lurks under my cylinder-head
I don't know much about turbos, but from what I have seen on *most* FI M20s, the snail sits close to the oil filter. I would imagine the thin wall of the screw-on filter will soak heat like a sponge. I could be wrong.
