anyone know the cost of blue printing the m42?

and would a port and polish ($800) be a worthy investment when i

rehone, balance, plane the head, and replace seals/bearings etc

before going down the chipped 10-12psi forced induction route with a rrfpr?

also valve springs would they need to be uprated?

and would it be worth looking into solid lifters?

thanks again

Oh click RRFPR = Rising rate fuel pressure regulator

oh ok again what would the cost be for a reasonable chip?

thanks again everyone

having a quick look on m42 club and theres afew ppl using the stock computer with a rrpf or a boost reference rising rate fuel regulator 12:1..

anyone know or can help because theres no way i can afford to spend 3000 on a ecu

wow i didnt realise the cost of a stand alone ecu system..

alright so a hone and new pistons, metal gasket, megasquirt and some new injectors and turbo set up?!

does anyone know about the Karl Schmidt pistons on trademe or know of using mitsi evo pistons?

does $450 sound like a reasonable price to pay for the bare motor?

sweet

like i said the sheap engine ive found has a blown gasket (needs to be replaced anyway) so a re bore would be good is +.25 the next size to bore to?

and what sought of CR ratio is your mate running? is he in hamilton?

oh ok i wont bother about stroking then,

still leaves me with new pistons does anyone know more about the misti pistons?

would solid lifters from a s50 be a worthy thing to look into for increasing redline or again dont bother?!

thanks again

hmm so perhaps a m44/m47 crank with a slight over-bore with s50/mitsi pistons would get me around 2 litre, if all else fails i could keep the m42 crank as (correct me if im wrong) they are forged.

if i could put a copper gasket on there and lower the compression alittle then i should be able to run 10-12psi safely?

one more this may sound stupid but could i fit roller rockers from a m44 onto the m42?

Cheers CamB for the links, heaps of great info. and yea it is a pain.

300rwhp would be amazing on a stock m42

i may be looking at a 1 that has a blown head gasket from the local wreckers and re-honing that etc.

does anyone know of a company who makes reasonably cheap forged pistons? or pistons from another motor that will fit once i rebore?

also is it worth looking at stroking the engine with the turbo or would this make it weaker/not worth it?

Hi there,

Not by any means building this now but i own a 318 and want to put a m42 into it with abit more go, forced induction seems to be thhe way to go. im after about 250-300 horsepower..

has anyone done this?

And any reccomendations on setup? having a search on good ol' google and megasquirt, t3/4/5 turbo bigger injectors, metal gasket fuel pump etc should get me there but im still abit lost.

im only a student so a dont have an open budget and have looked down the 2.5 swap but if i did this i would have to replace my suspension, struts and brakes etc so cost will end up being similar anyway so why not go for something less common.

lots and lots of questions, any help would be appreciated guys cheers!
