e30 m3 s50 swap questions.

[1-pippin]

so im looking at a s50 swapped e30 m3 that i might buy, but i have a couple questions. what is the acceleration like with this swap? like what can it compare to? or what 1/4 mile times are common with a slightly modded s50 in an e30? im coming from a stg2 s4 with 350hp, it gets about 13 second flat 1/4mile times, i want similar acceleration but better handling, i know the handling will be much better but im still concerned about acceleration.

When you say similar acceleration what are you expecting ? ... nothing is going to launch like an AWD car, NOTHING. As far as everything else goes im not quite sure, a friend of mine had the swap done and the car is quick. Stage 2 S4 quick... i don't think so.


Keep in mind a 1995 M3 with a perfect launch can do the quarter mile in 13.9 seconds... the e30 should weigh considerably less than an e36 m3.

Ive always wanted an e30 m3 since i was little. but now that i graduated and got a real job with money im deciding on which m3 to get, e36(faster) or e30(better style). so i did some math with hp/lb and NM/lb with the e30 s50/52 swap. all percentages are baselined on the e30 s14 m3:::: e30/s50 24% hp/lb, 79.4% NM/lb...... e30/s52 24%hp/lb, 88% NM/lb........ e36/s52 4.5% hp/lb, 60%nm/lb.
so what i see the you get a decent hp boost but a real torque boost from the extra 2 pistons now i just need to find one
