New member, Old Questions, pleas help :)

Hey guys, i am new here of course and i just wanted to ask a few basic questions that you have probably seen before and i did not see what i wanted in previous threads so i thought id just ask again.
  1. What is the difference between the 318i the 325i and the 325is (in a nutshell)
  2. What would be the best car for track racing?
  3. I am more interested in the DOHC 1.8 Litre, is my interest misguided?

I just want to buy an E30, the 318i model can look very nice in my opinion and there would not be much difference between that and the 325i, i want to eventually build it into a track car and i am going to spend alot of time and money on it, so i want to have the right chassis and possibly the better engine to either work on or swap, but just for general learning of the feel of the car, i will be doing suspension / weight reduction / brake applications first so i am really just looking for the higher reving more powerful engine.

Any help?

Thanks for your time.

1: in a nut shell ..
early model 318 is dog slow and has an m10 4 cylinder
late model 318 has an m42 and is faster then the early 318
early model 325e has the m20b27 which was built for good MPG's.
there was a SETA but you prolly wont find one
the 325i has the m20b25 which is the fastest in the bunch
the 325is ha the same motor as the 325i but with a better appearance package

you can look up the motor difference on google if you want HP/TQ numbers

2: 325i/s would be the best, 325is will have more comfertable and supportive front seats.

3 so your looking for the late model 318i/s. 325 would be better then the 318.

the 318's look exactly the same as the 325's do. the only body differences are between the late model and early models. late models have small plastic bumpers while early models have big aluminum bumpers

Thankyou a bunch for your speedy reply mate i appreciate the input, the m42 seems the way to go but i dont want to regret not having a 325i with the m20, its just a SOHC 6, compared to a DOHC 4.. i would feel more at home with the M42, not to mention with rising fuel prices etc it would probably be the more economic option, and i am keeping that in mind as it will be my daily driver with some track styling.. are there any defining points of difference between the 318i and 325i shell? a late model 318i would be my preference at the moment, but would one have something like IRS suspension that the other does not? just looking for defining chassis factors at the moment

EDIT:
i feel like a spastic for mis spelling please in the title .. sigh..

as it stands for my current preference my best bet would be a E30 318i, 1991 model which comes with the M42?
and as a side note, is there much of a difference between the 318i and the 318is

shells are the same. same general suspension.

spelling isnt a serious issue here, most of us type fast and dont even pay attention to spelling errors.

not sure if your asking but yes the 91 318 will have the m42. 318i is just a base model 318. the 318is will have the sports package. nicer seats and some very minor styling differences, no real mechanical differences. the sports seats are alot nicer.

I have a pair of sparco evo 2 seats that i am considering putting in, otherwise if that ruins the style of the car, i will be getting some later model BMW seats, having them completely re trimmed and using them instead , do any other models besides the 1991 318i, such as the 1990 version come with the M42? this car is probably going to consume alot of my time and money so i am just doing research before i go out and purchase, and once again steve i very much appreciate the speedy replys..

If the answer to the question of does the 1990 model or any model before the 1991 of the 318i e30 come with a m42 is no.

Then i have decided on the first BMW i am going to buy , very excited.. and if anyone has any words of wisdom, or would like to try and convince me otherwise, 325i or is etc i would LOVE to hear your point of view, but for now i must go to sleep its 5 am and i have a job interview in 4 hours.. but il wait up for 20 minutes for any speedy replys , i will be on in the morning to read any opinions.

i believe 1990 has m42 318's also. but nothing sooner as far as i know. i have never beena fan of aftermarket seats in an e30. stock e30 sport seats or early vw recaros are going to be the nicest option. newer BMW seats are just inferior. they arent as comfertable nor are they as supportive.

316's were the worst e30's ever made so if anything they were. i know early US spec 318's were, so im sure euro spec early 318's were too. somebody from germany/ somewhere else should chime in

Ah, never owned one. Looked at one a few months ago hoping it would have a rad I needed for the M50. Then found out from a write up that it needs the M42.

steady on about the 316i steve! hahahaha.

OP:
euro early 318i has drums. late model sometimes has disks, sometimes has drums (i think this must have been an option). disks were SE on 320i and 325i. You can upgrade to disks easily enough, although not having done it i cant give instructions. google is your friend here.

My friend has a 1990 318i and im 90% sure that it has the M42 in it.

Australia has euro spec. america is the only place to have US spec.. surprising i know lol.

btw welcome to the 'fest! its good for me turning my head toward left toward australia rather than right all the time
