First OFFICIAL TWINCHARGED M20 BUILD

Can't help with the turbo, but I got my ARP studs (head and main) from VAC.

Kinugawa and turbonetics have plenty of turbos in your price range and they are NEW with a warranty

ALso that is


nomade30 on E30tech is the best place for E30 headstuds.also that seems extermely overpriced for a holset.

My holset was $150USD in 100% working condition. A rebuild kit is only $60USD.

I kind of got a great deal but I would NOT pay over $400 for a holset. and at $695 your getting into brand new turbonetics territory.

Thanks Guys for the info. Looks like ARP studs should be next on my list before building the turbo side... Should I remove the head to install them...headgasket only has about 10000KM..

and I also have to do the dreaded camshaft seal..:( I think I may as well pull the head off...

Winter is long here in canada so ....lol...

I've done some Hondas and Miatas where I didn't pull the head, and had no problems. Provided you follow the proper torquing/untorquing procedures.

Cool man thanks. I think thats what I will be doing!!

Sent a PM to Damon (nomade30) for some ARP studs I will be ordering them tomorrow!! Found 60# injectors should be getting those soon too...

Still undecided on turbo size... cant seem to make up my damn mind!! lol...

E30 is not a honda.


OP, do it right and pull the head. If you don't do it now, you will later and you don't get to choose when.

I know, that's why I qualified my experience and didn't just say, "yeah, it'll be fine."

What's so different about it?

[Denny]

I just read on another forum a turbo E30 where some guy changed to ARP studs without removing the head and it was fine... so am sure both ways is fine.

Not that I care too much BUT seriously some FUCK just gave my thread 2 stars... LOL... whats wrong?!? A twincharged M20 is not cool enough for you...

lol nothing wrong with doing one stud at a time I did that and daily drive at 20psi just fine, going on year of being boosted on a 23yr old head gasket.

remember when BMW did the hex heads to torx head bolt update and did the exact same thing, only pulling one at a time.I guess BMW thought E30's were hondas...

no need for misinformation

BMW specifies that you can replace the head bolts without replacing the head gasket.

lol. No misinformation here. I'm glad your headgasket is staying put so far. My experience over the years with un tensioning a head bolt for retorque or replacement has ended in head gasket failure more than 50% of the time. It usually doesn't happen right away, hence my comment.


Bmw suggests (last time i checked) 15k oil changes and never replacing diff and trans oil, do you follow their wisdom regarding that as well?

Warranty protocol is usually less than ideal and biased towards costing the least.


Not looking to start a pissing war, it was just that my personal experience differed from was being stated in the thread so i thought i would present it. I want OPs head gasket to hold so we can see how this performs !

And I appreciate both your recommendations and concerns :) one or way or the other it will work for some time until I build my M30 and go all out

Ordered my ARP from nomade30 .... cant wait to join the 20PSI club

[LJ851]

...until I build my M30 and go all out

Now you are talking! You are going to use the stronger B34 block for big boost, right ?

I understand, it was the honda comment that threw me off a bit. BMW did it to E30's as a service update and didn't have issues with 50% of the headgaskets going out. Just do it in the correct order and you will not have issues with it leaking. Head studs clamp so much harder than head bolts you wont have issues.

yeap its a euro 1991 E34 motor. Took it out of my old winter beater with only 160 000 original KM. Sometimes am so tempted to just sell my supercharged M20 and build up my M30 with the same setup but use my spare thunderbird M90 supercharger. Since the M20 is already all installed with 150 compression on all cylinders I may as well finish it up and take to the max :)

Yeah Cant wait to get them installed and see how 20PSI is going to feel...:evil:

E34 M30 is a B35. Bmw lightened the block when the B35 came out and it is weaker than the B34 that it replaced. On a boosted B35 the head studs tend to pull out of the deck at much lower boost levels than the B34 although the head flows more in stock form.
