hi im new to bmws and am looking to buy one

i can see that the 328 and 325 are similar in power but one is a 2.8 and the other 2.5 but which is more tuneable(or which gives more bhp per £ when modding it )?

also whats the difference between the 323 and 325 both 2.5's but a 20bhp difference is this just a remap?

oh yeah these are the e36

sorry if this is an old question.

Differences are commonly achieved via the ECU, TB and manifold to kerb the power... Dunno why really, maybe an insurance and/or emissions thing !!

Well said Dabs,I could go into all the differences between the 323/325/328's but its loooooong and youve pretty much nailed it :) and seein as my 323 now produces more power than the 328 the differences are now irrelevant to me,lmfao

Thx Dude ;)

snypa how much did the remap cost?

Cost 300 quid mate.from a place called EvolveAutomotive,they are BMW remap specialists and you wont find anybody better !! heres a link.............http://www.evolveautomotive.com/

bit far away from me mate lol

strugling to find anything near me at the min, even coupes are going too much for me :(

but im not giving up

Never give up Matey... There will be a rolling-road close by...

i meant a car ill worry about the rolling road when i have a car lol

bit far away from me mate lol

but im not giving up

I ended up travelling down past brum for mine mate,,, was well worth the 3 weeks not driving and searching for the right car!!!

600 mile round trip,, got a major bargain and a wee gem that i've had scoured over twice and can only find a brake pipe corroded!!!

Excellent advice Dezza... Some peeps buy the first they see and a week later a minter comes along for less booty ! Arr-Arr-Arrrr

M50 engine=2.0/2.5 24v vanos/non vanos fitted to late E34 and early E36

Cast Iron block,Larger more power friendly inlet manifold and throttle body and yes the ECU was mapped slightly differently however it was within the "adaption" limits of a m52.

M52 2.0/2.5(badged as 323/523)/2.8

Ally block much lighter! the engines themselves cannot be interchanged without a custom engine mount being made, more restrictive inlet manifold due to tight emmsion laws,however can be replaced with the earlier manifold with an adpotor kit (about £80) which will take the M52 2.5 from 177-190 and the 2.8 from 196 to 215 bhp.

So in idiot terms buy a 328 sport coupe slap a earlier manfold on, re-map it say hello to about 220=230 bhp with the sound track from heaven under the bonnet.

hope that helps

Lol.... And keep it to yourself or the Insurance man will hit you with a sledgehammer !!! :o
