Swap 1/4 Mile Thread

[mr_naler]

Honestly, I think if you know what you're doing you can pull better times. If you make up a competent intake system and have a good running M50, a proper rear end for your transmission, know how to shift and launch you'll be into the 14s, if you've got M3 cams in a VANOS motor and a proper tune you'll probably be in the low 14s. Certainly faster than mid 15s.

I've got some s50 cams sitting in my garage. I have a g260 tranny with a 4.10 lsd. I would not really want to trade that out. I was really aiming for 13s high, low, or mid didn't matter, I just wanted a 13 second car that I could drive pretty regularly honestly. I started looking into megasquirt today. I still have no clue about it really, but am interested in learning more. Weight reduction is what I'm trying to figure out right now. Anywho...

So I just read this entire thread. I had pretty much laid out what all I wanted to do to my e30 make it do ok at the track; M50 with mods, some weight reduction, but after seeing all these 15 second runs(My Stock engine 93 teg did 15.01) I think I will be doing a LOT more thinking beforehand.

arguably his best mod is the weight reduction. 2580 with him in it... it's a 2400lb e30 vs your 2750 lb e30

Yep. My m50 e30, that weighs 300lb more, ran a 14.4 @ 95 on the same tires, on the same day. It's clearly faster up top, but the lighter m20 car goes through 1st and 2nd quicker.

I don't have an e30 anymore :-|

Yes, this makes a huge (cheap) difference. My S52 E30 weighed 2,608 with me in it and was very quick. Too bad I never made it to the drag strip with the S52.. It hooked up extremely well until I toasted the clutches in the 250k diff. I can't wait to hit the strip with my new engine.

Wow... really? What other mods?

Impressive :) They are basically slicks though, lol.

What was your 60 ft.?

Don't remember, but it wasn't good. 2.2 or something, probably.

[884door]

Everything I had listed.

Also, long tube headers and 2.5" exhaust, which probably don't do anything. The v710's hooked up very good. Clutch drop at about 4k and go. It actually bogged a bit.

I ran a 14.6@92 in my chipped m20b25 87 325is, 2580lbs w/ driver, on 205 v710's.

its not an m5x/s5x swap, but i ran a 15.05 in my 318is with an m20b25.
it had an unknown make chip, stromung cat-back with test pipes, cone filter.

i was reading through this thread and saw a few posts regarding an m20 with these mods unable to run near 15 flat
