so what e36 chassis is the prefered one to build?

[iambhooper]

i'm sure the Z3's are a blast... however donor's don't turn up at a reasonable price (to me).

so is the '92 considered better because of the dual valve springs? what advantage does that offer?

[NORRIS]

Also the Z3 has semi trailing arms. Which can make the car even more fun to drive, but I think the multilink that the E36 uses is more tuneable and more drivable.
I'm under the impression that '94 is the year to get because it has Vanos. You might want to check on that.

The 92 is the only year without VANOS, and is also down half a point on compression.

Donner car's not as important as it used to be, becuse you can use any of the e-36 motors as long as the chassis is the same.

e36 non vanos's are not better just different. With the vanos motor you have the stock valve springs which are not that strong and if you bring a car up to redline alot they can break. Alot of people cheat and use the larger e36 m3 one that are tapered and that resolves the issue, however just saying the the 92 non-vanos has the dual ones from the factory. With the new vin rule you could really get any chassis and then pair up a motor and classify the car at that point. ITR is def up and coming and ITS is dying out.

so from a reliability standpoint, the earlier head is more durable than the later design. i'm familiar with the vin rule, that's how i changed the CRX to ITB.

[hondaman321]

the two engines are very similar. I was just letting you know the difference, however since the vanos motor was around longer it may be better to go with that option 93-95 e36 and i believe 92-95 e34. The non-vanos was only in 92 e36 and early e34's so they are not as common if you need replacement and I think the ecu's are different and harder to come by.

OK, so I'm hooked on the ITR/ITS group. I had never driven a BMW until I got a 325 in a trade a few weeks ago and I was impressed. It is now my daily driver. I just purchased a 1996 328 from an insurance auction for the interior and have decided to cage it for ITR. The engine has a rod sticking out the side so if anyone wants to sell one let me know. Anyone want to give up their info on shock/spring/bar info? Any help is appreciated!
