engine and drivetrain lots of questions with no answers. please help me out!

[Robotin]

so after tearing down my engine. and getting some professional advice. it is done. local machine shop said they would need to completely rebore the block. and i dont wannt wanna pay that much for the larger pistons.

some pix to show the damage.

i was hoping to find another engine i could just "drop in and go". but to no avail.

but i do have a hook up on a 320i engine. it has a 1,8i head. i was hoping i could just use that block and head. and just swap all my top end stuff over to it. (i dont want to convert it to EFI) so would it be posssible to just swap all my top end stuff over to the 1,8i head. but i noticed the fuel injection holes are on the head. so how would i go about getting those blocked?

i am brand new to the 2002 game, and am trying to understand all of my options right now. the problem is i need this car to run like yesterday. getting to work in very hard without a car.

i have a budget but want to do it right. not one to cut corners.

please help!!

wholly meltdown batman sorry but that=epicfail

You should post a wtb add in parts wanted. Someone will have what you need.

[Robotin]

i did post a WTB. and no response.

ive also thought. what about the 320i block. with the e30 head? becuase the e30 head doesnt have the injection ports.

sorry about all the questions. but i have gotten no definitive answers. and like i said. i am new to the 2002 game.

i have loved the 2002's for years. and hav e finally gotten one. and i am so happy. but i am most distressed that i am not able to drive it right now.

That is pretty ugly, compadre.

In what part of the country do you live? These motors are not that hard to find. You could likely get a long (or short) block for a reasonable price from a local recycler.

i gone around to a few yards this week. and found 3 e21 320i's. and 1 2002 with the block still in it, but the head was off and it looked as if it had been that way for a while. the cylinder walls had a few light rust spots on it. but i think i could hone it. and i would b good. but then i have to find a head. and i would like to get another 121 head. but from what i have been told. they are hard to find. and are on the pricey side.

i have the hook up on an e30 head for super cheap. what would i need to do to make that head work?

from what i read i would need to put the 2002 cam in it. but is that all?

i really want to keep this car carburated. i love carbs.

[Chris_B]

Uh huh. So in what part of the country are you located. Somebody may be able to give you a tip on where to find a motor.

[aa/fd]

Wow what do the other three cylinders look like?

Those ring bite and scuff marks on the cylinder wall look like what a 70's era Nitromethane fueled Chrysler would do while digesting itself

I might be able to help out if you can help me out a little:

1) Where in CA are you located

2) Do you want to assemble/build a working motor of your own spec

3) Are you looking for any complete long block (top & bottom end) to swap

I have a 2.0 e21 engine and with your 2002 oil pan and mounts it will drop right in and with a few bits changed over for good measure. The good thing here is that the distributor turns the correct direction for a 2002.

Check out this ebay listing. It's been on several times. Make him an offer.

[Robotin]

i will definetly check out that ebay ad.

maybe its just me. but isnt $2,000 kind of a lot for a m10?

ive seen complete m10s from e30s go for like $300.

i am in the Los Angeles Area.

i would love to just rebuild a motor. or just minor budget upgrades.

like if there are any cool OEM+ mods.

other than that. i really just want a strong running motor.

That's a $4000 operation, bare minimum.

You won't find a set of used pistons that are worth re- using

and that runs you into boring.

At that point, everything else needs to be redone, since, well,

you just dropped over a grand on the pistons and machine work,

an oil pump's $400 now....

yadda yadda....

While a used longblock with decent compression shouldn't

cost you over $500 around here... IF you can find one.

I dunno about LA.

If you are on an extreme budget Your best bet is to find a known good engine that's been pulled for a m20 or some other conversion. And 2k is not a bad price for a rebuilt engine. Crate motors are closer to 5k now from BMW.

If you only have 500 to spend roll the dice on a used one and hope it runs.

i figured someone who recently did a motor swap would be willing to sell me their block and head. all my other things r fine. its just the block and my head that are no good. i would be fine with redoing some rod bearings or valve stem seals. but i dont want to buy a block that i would need to erbore. if i wanted to do that i would just keep my old block.

would reboring the block and getting the oversized pistons change the displacement at all? would i see any power gain out of that?

[mudchemist]

I have a motor that I pulled from my car 3weeks ago. It runs. Compression is 105-115 psi and even across cylinders. That is on the low side. Vacuum is steady so it is most likely tired rings and not the head. 121 head. Pulled well enough, no smoke.

I am willing to sell the longblock if you go that route. Less the flywheel. AS-IS

There is no cheap way to do a proper rebuild. Even doing it yourself will be $2500 without performance upgrades. I am finishing one up right now...its time consuming, detail oriented, and expensive....and if you screw something up there is nobody else to blame. I've rebuilt motors before and still managed to screw up the oil seal this time....it happens.

The only real savings you get rebuilding yourself is from the lack of warranty.
