N52B30 in e30 conversion ? possible ?

[BMUU]

Hi, Has anyone done this Swap? 200kw n52b30 into e30 ?
what computer system do these run OBII ? what other things would be required?
thanks, Steve.

Whats N52?

[rThor432]

New52. It's got dual VANOS and Valvetronic. It comes in the new-ish cars starting in 2005/6 depending on which continent you live on.

N52 is an M54 with much differenct block technology and valvetronic in addition to dual-VANOS. I was able to get rid of the electronic throttle on the M54 and replace it with a standard throttle, the N52 has no throttle body, the intake valves have a pivoting arrangement that change valve lift as the throttle.

The stock computer would be best to run it but you would need a major wiring harness graft to keep it happy. Standalone could certainly work but nobody has made the effort yet, as far as I know.

crazy!

you won't do the swap so don't bother..

The n52 is nothing like the m54, its is a tri metal block with a bedplate. It uses aluminum, magnesium and steel. Completely different in every way. The cylinder head is from the ground up new. The n52 does use a throttle body only in conjunction with valvetronic. You will never get msv-70 to work without a dedicated can bus, and a standalone computer capable of operating valvetronic is going to be more than the cost of the motor. For 255hp from the n52b30k it isnt worth the time or effort.

[rThor432]

^^You are right about the throttle body. To clarify-- It is present, but only used for startup and as a failsafe if there is a problem with the Valvetronic system. Once the car is running the throttle stays open and the Valvetronic completely regulates the intake of air.

Wish I had a picture of the system. I rebuilt one of these (a 3.0 litre) and it was a very neat system. Beautiful motor too, short block looked awesome with the brand new pistons and sandwich metal block.

Ok, maybe I was generalizing too much by saying it had a much different block.

It's like an M54 because they're both 3.0 litres.

Given some time I'm sure I could get it to run but it's not worth it right now.

[BMUU]

Yeah, does sound a bit complicated, but wouldnt it work if, like the s50 type motors, you kept the original computer and key setup from the donor car? I like the thought of a light weight 268hp @6650 with a fantastic tourque spread peaking @ 2750 with 315 nm and keeping the balance of the car right.

You will need the cluster, dme, cas, zas, transmitters, keys, and a can bus to run everything, then you'll have to make sure you source everything from a manual car as the mechatronics unit needs to stay with its coded units. It is a very powerful and complicated electrical system. Not to mention the mechanicals. First time I swapped a cylinder head on one took me over 8 hours.

Does anyone know if it will even fit in the e30? Im pretty sure the oil pan sump is in the rear and there arent any aftermarket pans available as far as i know. Custom headers would need to be fabbed as i dont think the convertors will fit down in the e30 bay. Also they use electronic water pumps with complicated hose systems, not even sure which radiator would be compatable. And you' have to find a way to make the stock airbox work under the hood or build a custom maf as the maf is built into the airbox.

All i can say is find out what turner does to their new e90 race car for engine management, then get ready to do some serious fabrication.

[rThor432]

^^Turner would be an excellent contact to start with if you are really serious about using this motor.

I understand that it's modern, and has double VANOS, and so on, but you can make that kind of power with a US S5x, so why bother with the unknown? You will end up spending silly amounts of money.

For what it's worth, my friend's Euro S50 dynoed at 354 hp with a flat torque curve. The engine was plug and play with Treehouse's adapter. His conversion would probably cost half (or less) of what an N52 will run.

"you won't do the swap so don't bother.. "

OK, you were right etxxz :roll:. But Us mortals must ask the questions to get the answers so we know why we wouldnt do it :-D.

From what you guy's are saying, It looks all too complicated for the results, I think Ill take your advice rThor432 and go the S50, was that Euro S50 you quoted above a S50B32 ? cause thats where it looks like Im going :nice:.

[rThor432]

Well, you are in Australia, so the Euro S50 would be your only choice. Yes though, that was a Euro motor. Only modifications over stock are the intake (carbon fiber intake), custom headers, and a chip. Pretty impressive power in my opinion.
