our bmw e34
Here"s a potted description of our e34 project, starting with a std 530i, we fitted a full poly bush kit replacing all std bushes, fitted uprated and lowered gas shocks and springs, along with strut braces, removed all the interior of the car..bye bye leather and walnut!,stripped out alll the carpets and trim, boot liners spare wheel etc and fitted a pair of cobra buckets with 4 point harness"s, recoloured the entire dash/door cards etc in black, welded up the rear doors for rigidity, then removed all rubbing strips, badges and clutter from the outside of the car, filling and smoothing all the recesses and gaps including the rear door apertures/handles etc, next the bodykit was trial fitted, adjusted and refitted/ blended, as well as making a new exhaust system with quad 3 inch tailpipes, tinted the rear lights, replaced the front indicators with crystal ones and fabbing a cold air induction kit, as well as modifying an impreza rear spoiler to fit in place of the std item (not in pics!), cut some vents into the the bonnet, blacked out the back windows, finally gave the car a quick paint in matt black and adding e39 m5 alloys custom painted in black pearl..with batman logo"s for humour value! as a result of this the car now weighs over 300kg"s less than std with performance/ handling and brakes all improved for it.. , update, we,ve now added a pro street bonnet vent, and removed the old 3.0 v8, replacing it with a 4.0 complete with box, ecu"s etc new engine remains more or less stock at the moment minus the dsc throttle rubbish, airbox and exhaust mods, there will be some tuning work going into this motor very shortly as well as some forced induction... wait and see!,
Update, after a huge amount of faffing about with bits not fitting we finally have a new diff installed, originally from an e34 535i its an lsd with a much more suitable ratio of 3.64 (from 3.15).. acceleration massively improved... supercharger on the way!
UPDATE, long overdue!, fitted vortec vs2 charger running 8.5 psi, and promptly blew a piston!, due to incorrect enrichment!, so we went back to the start and obtained a late obd2 m62 4.4ltr engine, converted it to obd1 system, ran it up on the rolling road at interpro on 6psi boost, after enrichment problems were sorted we have 404 bhp, but cannot up the boost as the airflow meter is now maxing out.. also getting over 60 degrees of intake temp.. so back to the drawing board, just had a handmade intercooler fabbed up along with associated 3" pipework this should bring the intake temp down and allow us more boost, also fitting a recirc type dump valve to drop inlet pressure when off throttle and add to the cooling effect.. we"ll see what power we get soon..
