Any of you see BMWSOB's latest run? (on the right)

Word. It's my all around car. Since I went with the coil-overs and all poly urethane bushings, daily driving the car in wonderful LA streets sucks! :down:

I always warn girls before they get in the car that the ride will not be very "smooth." :nice:

As far as power, I'm very interested in the 5.0 swap that Rob at e30 motorwerks started on. An aluminum head 5.0 is almost the same weight as an m20! With proper heads/intake manifold/cam and tune that would be a real torque beast in an e30! :crazy:

I know I have to do the same thing now too. I just cant help and today I got another set of wheels :p. I have an ls1 if you want a 5.6.

Well then you'll rape me!

If I get bored after cams, I will be doing a 2.8 m50 NV turbo with custom turbo cams, worked head, and coated pistons. Even though I could just boost the s52, I want to do something a little more challenging. :D

But I wanted to do the Boosted M50 NV

Thats why I am getting a supercharger but I am looking for another e34 for a chevy swap and maybe a turbo or two. I know your car is a street car so thats a big diffrence from mine. I have nothing in my car at all so its not very nice to drive on the street.

I really have to stop spending $ on my car, I should be saving for a house!

damn, I need to get my car buttoned up... now.

This! :hitler:

Already have cams and possible a supercharger by the end of the year.

I used to run an m50 with getrag 260 and 3.25.

260/3.73:
3.83 1st torque applied: 14.29:1
2.20 2nd-8.2:1
1.40 3rd-5.2:1
1.00 4th-3.73:1
0.81 5th- 3.02:1

zf/2.93:
4.21 1st torque applied12.33:1
2.49 2nd-7.3:1
1.66 3rd-4.86:1
1.24 4th-3.63:1
1.00 5th-2.93:1:1

zf/3.25
4.21 1st torque applied: 13.68:1
2.49 2nd-8.01:1
1.66 3rd-5.4:1
1.24 4th-4.03:1
1.00 5th-3.25:1

So yes I do have somewhat aggessive gearing considering how freely the s50 revs. Its all in the first 2 gears, they are too short. My first gear is only slightly longer than yours if you are indeed running a ZF with a 3.46. The most common ratio is a 3.25 which is probably what I would use, if I decided to switch, but there is no real reason to.

I was misinformed. Everyone said that the 260+3.73 is about the same as the ZF+2.93. With your calculations, it's the ZF+3.25 that is comparable. I'm guessing the 260+4.10 is more like the ZF+3.46. Sorry for the misunderstanding, and I am actually running the 3.46. Ideally I'd like the 1st & 2nd gear ratio of the ZF+2.93, and the 3rd-5th of the 3.46! :up:

I bet if I had traction and pulled some crap out of my car I would have had a mid 13 sec NV M50...

How'd you like that setup? Which M50 were you running?

[e30s52]

Which kind?

Shricks

[sharksforthecup]

Already have cams

Which kind?

[D-rock]

Usually 215-220 crank if it's the correct chip with good intake and exhaust. Thats nearly a 30hp gain.

So thats almost an s52 so is it really worth it to re swap?

God im getting a new diff! And i couldnt find if i had a zf or not! But all i know is that thing was so shinny and silver looked new. :/

I'll be a little lighter, with cams by then. And I'm sure you'll have at least the same. ;)

What was your 60 ft with the slicks?

Already have cams and possible a supercharger by the end of the year. I dont know but it was really good sence they just sprayed the track down when I went. I beat a gt500 on my pass lol.

I will see if my dad can find it so I can post it up.

Another edit I talked with him a few minutes ago and he found one with a 2.19 he said but that might from another car sence we ran his car, and then my uncles charger too.

[e30polak]

I can grab my slip during thanksgiving sence its in my room in wa. But I have a ZF tranny, 3.46 lsd rear end, soft spring in the rear with old crappy bilstiens, and I think they are 15x8 or 9 slicks that I barrowed off my friends car. It was a high 12 and my reaction time was .004. I passed the the line doing 108 or 110 or somthing like that. If you come to the picnic this year I will do a pull next to your car ;)
