best mods for my m20??

Post Sat Jun 23, 2012 1:45 pm

i have a high comp m20 lump in my tourer and want to try get a little more power from her.

a friend and fellow zoner (driftnething) is going to be doing a stroker conversion for me when i can get the engine out and over to him so i wanted some advice from you all as to what would be worth getting for the build or adding to to optimize my preformance for as little pennies as possible!! although i will spend money where it is needed.

does any one know exactly what is needed for a maf conversion?? i work at a breakers yard so getting bits from different cars is quite easy but we dont get many e30's in!!

any sugestions on enhancing preformance or response is appreceated.

dan.

^^^this plus the following.

full service, all filters, fluids, plugs, leads & if need be new dizzy & rotor arm.

if budget allows then port, polish & gas flow the head to complement the new cam,
6 branch manifold, full stainless steel exhaust, X-pipe on the end of the down pipe's, cold air fed induction set up, & if possible either a 2.7 or 2.8 stroker conversion & finally a RR remap to set it all up & working as it should.

but it all comes down to budget & personal choice.

Get a decent chip in the ECU to bring out the best from it.

You can fit a Miller MAF, which uses a Ford Mustang MAF unit, together with a chip change to the ECU.

I can supply a similar chip. A MAF gives a very nice smooth throttle response, though won't necessarily give much extra power.

That sounds good, 200bhp should theoretically be achievable with a BTB2 manifold then going on Barry's 17bhp increase on a standard low comp M20B25.

Is the M30 AFM a straight swap and is the chip a pre-programmed one or a remap to suite the mods?

Dmcl on the zone mapped the chip with the m30 mods in mind, let him know what u want, he can do just arm, or just injectors, both , mild wild etc

At the mo i have hottuning 6 branch, with no x pipe, so brb might help? But for an extra £600 ???

if you don't mind me asking how much did dmcl charge for the chip? Been thinking about the M30 AFM & injector mod.

i would get ant to do the chipping over some guy who doesn't even develop anything on the dyno

Does your headers run into a single or split system? If a single pipe then you do not need a X-pipe but if you have twin pipes then get one. It basically scavengers the exhaust gas from the other header, leaving it under a partial vacuum. This then improves gas flow out of the cylinder on the exhaust cycle.

it is a 2 piece manifold, 3 into 1 x2, so 6 into 2, twin pipe all through,

i got this manifold cheep as it was holding the owners garage door open

, it didnt have the x pipe with it, i needed to change mine as it was cracked. i will get one at some point

thanks
