N52 Swap Discussion

Yeah I would prefer that also. But I don’t have a lift at home and I’m pretty sure my jack stands don’t go that high

I don't have a lift, either. The body is jacked-up in stages and supported on the frame rails high enough to roll the engine assembly under the core support. Then the body is lowered onto the engine (while it's jacked-up a bit as necessary).

I've done this single-handed a few times and it's easy.

How are you guys installing the engine. I don’t have a load leveler for engine/trans package might be a challenge to drop in, although I can prob borrow one. How do you do it?

I prefer from the bottom. I attach the front subframe under the engine a lift it up.

Thanks Caperix…Yes, I modified the Datsun front crossmember to accommodate the stock e92 motor mounts, then fabricated steel supports on the N52 block side to position the engine properly and isolated them with 1/16” aluminum against the magnesium.

Very familiar with HybridZ, and will share my progress once I have a bit more to show….Gotta get the lions share of the electrics sorted and the car rolling under its own power, then do a nice summary of the work.

The car is a lightweight at around 2400lbs (not unlike the E30) but the block is indeed cast iron…all in it weighs 425 lbs. Few in our community run the stock 4-speed anymore and swap in a 5-speed which is 101 lbs for a total of 526 lbs. Equivalent N52 and 6 speed is 458lbs, so 68 lbs of weight savings plus an extra 100+ HP will be nice. At the limit, the S30 struggles with understeer, so the reduction of this weight over the front axle should improve handling even more.

6th gear will be nice, but 3:54 rear end gears combined with 24.9” OD dia tires might not be best for highway cruising….taller gears would be nice. Should be a jackrabbit around town though!.

The S30 engine bay affords us the room for a multitude of swaps including V8, JZ, RB, and S54B32 but my rationale mirrors that of many in your E30 world…weight loss, improved handling,and cost. Plus there is just something to love about that inline-six sound eh?

Damn... it was made for that chassis. Stock motor was iron block? I know it was a light motor but I'm sure you're losing some weight while doubling? your hp, and 6th gear is really nice.

There have been a few FRS swaps as well

Looks great, are you posting on hybrid z as well? Did you weld tabs for the motor mounts to the factory subframe or is it custom?

A few more pictures…. I’m amazed by the ease in which this engine slips into the engine bay. Brake booster and 3-stage intake are quite happy together. Stock oil pan fits perfectly, Stock E92 radiator and fan assembly fit like a glove and without causing any fore and aft space issues. Hood clearance is snug but still allows room for the BMW beauty cover. I needed to buy 2 sets of AA style headers and used the 2nd 1-2-3 header section in the 4-5-6 position to get things to fit with minimal fuss.
I still have a long ways to go but feel like I’ve broken the back on this project. And so so appreciate the ground-breaking work you all have done with your E30 N52 swaps.
I hope to tap into this community from time to time and would happy to share my progress occasionally.
Thanks!

Thanks Hoveringguy….It lights up now!

IVM Mystery.

Love this forum! This is my first post:

I’ve successfully installed an N52 into my S30 (which is a Datsun 240Z) With Kassel EWS deletes done on the DME, engine fired right up on an engine stand using the 330i engine harness and accompanying mess of relays and power wiring in the e-box.

Several of you have cleaned up said wiring mess with the Z4 IVM and so am I. On the workbench, I’ve been able to light up all the IVM fuses (except F7) by activating the DME relay and VVT relay. F7 is a mystery! It supplies power to the injectors from the injector relay which is integral to the IVM. It should be easy, I just can’t locate the activation signal. It’ll be switched power (not switched ground).

That switched activation power could come internally off “Run/Start” Pin 23 X691 but doesn’t. How is this relay activated?

Cool project!

It may be that you need to apply power to pin 5, which is the only place F07 gets power from. This is from the WDS online.

Yes! The IVM is a much cleaner solution than the hodge-podge of relays, fuses and wiring that jumble the E90 cowl.

I have an E90 mostly complete harness and the Z4 fuse block. I won't be able to use it in my e46 application. So, I am offering here for sale here if anybody can use it. $100 for both. I have one of the connectors for the fuse block. I posted pics in the classifieds.
