E30 Zone

I own a f reg 325i and have seen alot of talk about enlarging throttle bodies. There are a couple of things i would like to no would this effect mpg and how much? Who can supply me with the part and costs? also who do you recomend for chipping/re mapping and is there any real gain in doing this an again rough cost??? any help on either would be much appreciated.

welcome to the zone btw

thanks for the help.please bear with me i as i am very new to this e30 stuff but i want to fit an lsd but have heard the diff casing needs modyfying?? and will my current shafts fit?? i have seen a lsd advertised locally for 300 is this a bit strong what should i be lookin at paying???

Eats tires, eats fuel, eats money, a 325 what else wouldnt have it any other way!!!!

£250 is about right for an e30 LSD, that's for a complete unit including output flanges.
To fit you just disconnect your propshaft and driveshafts, remove the old diff (four bolts on top and diff bush bolt at rear) bolt the new one in, reconnect the driveshafts and propshaft, set the propshaft length and preload the centre bearing and you're done.
Any e30 diff will fit any e30 without modification.
