how fast is your s50e30????

[blackhawkimpact]

3.73 LSD and a 240 getrag, car at about 2600lbs, full bolt ons and a TRM tune I can pull even with an e90 M3 through third. At higher speeds aero starts working against you, though.

I'm on the 4.10 LSD. can't wait to put on a 3.73 LSD. :)

I've beat 4 v8 mustangs

the new 412 hp mustang?? The one that the e9X M3 can't beat??

It was a vague post so I'm guessing its either one of the mustangs from 1965 to 2011..can't be too sure though

A buddy of mine is a pony car guy and said by his estimation (based on power,weight, etc) a properly swapped e30 should do pretty well against most (stockish) mustangs 05 and before.

I seriously doubt it was a new one. Even my F150 can beat an old mustang...lol

wonder if he meant Mustang II??

Mine is pretty fast imo

S50
dinan bbtb,
raceland headers
euro hfm
TRM tune (going to get updated soon)
decided against cams becuase i didnt want to loose low end torque
21# injectors
3.25 diff
getrag 260
lightweight flywheel
fan delete

soon to have
ferrera valves,
cometic head gasket and arp studs (for what? future boost maybe)
but keeping the compression stock
updates springs and retainers

I love racing on short road race tracks where the smaller less powered car has an edge. At streets of Willlow, I was consistently running about .5-.75 faster times than the e92 m3s with similar skill levels.

I bet that a properly driven e92 m3 would blow the doors off me but my power to weight ratio is great imo

You can definitely pull on an e46 M3 with a well sorted S5X e30. I'd pull on my friends stock Z4 M Coupe all day and that car is significantly lighter than an e46 M.

i cant wait til mine is done. i'd say about another week or so. thanks for the info

hey i have a question for you, how was your experience with raceland headers? mine should be in tomorrow and i ordered the ones with the flange on the end that bolt up to the e36 m3 exhaust because thats what i have. did you order the same ones and how do you like it??

[mohamadr89]

where can you find a 3.73 diff at for a s50?

I love them. I have the long tubes. They sound good, not alot of rasp, and the quality is great. I just had to put a spacer underneath my swaybar mounts to keep the headers from hitting the sway bar. I can get the spacers if you are interested in them. let me know

3.73 will be murdering your mpg at hwy speeds if you have the 260 tranny. you will be doing 80mph at about 4k rpm. I know most people dont go over a 3.46

You gotta come out to the Cerritos Meet so I can check out your ride! haha

what if i have a zf tranny? the guy told me the headers i bought were the shorty one. i couldn't tell the difference and they looked longer than the other ones in the pic. but i have the oem m3 exhaust so the headers i got have the flange that bolt up to stock e36 m3 exhaust. i just hope they work out as sweet as yours did!!

I planned on going to the last one then i found out I had a bent valve from the race weekend before...So now shes out of commision to get the head fixed.

The shorties will work fine.

A 3.73 with a 260 should be fine as those were designed to go together. A 3.73 and a zf is what will kill you. The stock gearing for the e36 m3 with a zf is 3.15 or 3.23, so a 3.73 will be too short.

So what do you recommend? Something between 3.23 and 3.73 or just keep it stock?
