N52 engine mounting (Z4 arms)

[hoveringuy]

Hi there,

Assuming we're using the stock subframe with E85 Z4 engine arms, a GS6-17 transmission (for the g260-like fit)... what is the combo of OE driveshafts that make it all work together? The more off-the-shelf parts this swap can use the more tolerable this swap will be for folks.

I saw in another post that the Tesla i-booster works with the 3 stage intake manifold using the E85 mounting arms, so it seems like this is piecing together better and better!

yep, stock subframe. I had run a custom subframe for the my rear sump M54 and it was kind of a pain, I wanted to keep this as stock as possible.

I have heard that an E36M automatic front section is the ticket. I just had a shaft fabricated for $600 from scratch. Came with new joints, and CSB, fully balanced. Just wasn't worth piecing used shafts together but I know that can be done.

Regarding engine mounts... What are the pros/cons of using Frank's (Garageaholic) mounts for engine and trans?
That was going to be my solution. Reassessing with these posts on Z4 options.

They look like good quality. The pro is that they're immediately available and they use a readily available M20 mount.

Only question for me would be how the engine position compares to the Z4 mount arms but I suspect its probably really close.

Go for it!

Hello N-swap experts!
I'm in process of coming up to speed on details for N52 swap into E30. Currently removing N52 engine, manual trans, etc from crashed E90.

Awesome, thanks for the confirmation guys!

That 2.5 above is M54.

Thanks.

They're kinda rare on ebay but widely available new, just checked ECS tuning and they're about $180 for the set, 321 & 322.

Huh, the 2006-2008 2.5 and 3.0 both had the N52, so weird that they would have different mounts

I ordered 22116769321 for 2006-2008 Z4 3.O si

[projectJTv4]

Just for verification / confirmation, the Z4 E85 arms are the ones off the 3.0i/si trim, not 2.5i?



Part numbers 22116769321 and 22116769322.

this makes me want to do find a GS6-17 and n52 engine swap my e30

They're dime-a-dozen right now, like the M50 was back in the day.

Here's what it would look like if it was further back.

N52 E85 engine arms, twin cam motor mounts, and the motor is as far back as m5x swap? Less than a ~ 1CM to the firewall?

I remember my M50 being much tighter to the firewall with the same clearance in the front, I still have at least 1.5" between the block and the firewall (without insulation). M50 had more drama with the heater core hoses, too.

So it could go back further, I just don't see a reason.

Nice work guys.

N5x swaps are going to be the next big thing! 📈
