oem head gasket if you can find one. blues will be fine

If its just temporary I would roll with a cosmetic head gastket and arp 2000 head studs.

If you are going to all out build a motor I would go with a 24valve though unless you want to stick with the m20 for some reason.
theres plenty of videos of stock 24valve motors making over 400hp

I'm still not sure on what motor I will build but I'm not worried about that right now, I know I atleast want to get an 885 head on the b27 and get it ready for 300whp at the most, and since that is all I am shooting for id like to stay away from arp studs since they are a bit spendy, and the cometic hg I think would drop my compression slightly and id like to try and keep it at the 8.3:1 at the lowest lol.

I know the headgaskets are the week point on these motors but...assuming I have a good tune running on the vems, would I be able to get away with a standard hg and metric blues on the motor if I am planning to not go over 300whp?

Just wanted to make sure before I jump in ;)

So what headgasket kit do you guys reccomend? And metric blues for head bolts?

If I do this, as long as the bottom end turns out to be fairly healthy it will probally see some boost, not much, probally about 250-280whp but just enough to play around while I build a motor.

Any other tips or recomendations for parts I will need would be great, ill be getting on this this week.

im pretty sure you dont need to swap pistons. but the only issue is that you'll go from 9:1 (stock eta) to 8.3:1. people talk about the seta pistons because then you can keep your compression at 8.5:1 (stock i.)

however, 8.3:1 is perfect if you're going to turbo it down the road.

so if i do the 885 head conversion all my problems will go away and i can use the 1990 325i harness and ecu?

*BINGO!* (...yes)

If he runs a 2.7i with a b25 ecu etc the later G260 won't be a problem. But If he wants to run a b27 with its standard ecu he may run into trouble w/ the two crank sensors.

[Vtec?lol]

No. He has a late model car but bought the early model engine

[ogbimmer]

^correct and thats because of the updated motronic only uses one crank sensor up front

so wouldn't it be the same for Robbie since he has the plastic bumper e30 also? on a side note I had no clue the early e30s were that much different :)

I don't want to throw mis-information at you, but it's be better to figure this out now, than later.

If you end up needing to run the two crank sensors; The one reading off the flywheel is going to be a problem...AFAIK late G260s don't have the hole for that sensor.

when I swapped in a 2.7i motor in my girfriends car it was a direct bolt up with the ihead installed and the oilcooler added.
