Biggest understatement right there. Even some standalones can't run the VHR; VVEL and dual DBW causes the biggest roadblocks.

I spent a lot of time and effort on my VHR swap kits.

The VR30 also falls into this since it switched to electrical VTC instead of hydraulic. So separate ECM to control this as well.

So for those interested I make Full VHR swap kits with working speedometer and triple meter.

I had a '95 M3 with Schrick cams (can't remember the lift and duration off the top of my head) turner motorsports shorty headers, some mild headwork (port/polish, upgraded valves and springs) Porsche 930 MAF (3.5" vs the M3's 3"), Jim Conforti 3.5" CAI, super sprint midpipe and Scorpion CBE, making about 335-340crank, over 300 at the wheels. 5.0s were no problem, lol. It's an extremely potent motor and the S50 in particular had a pretty violent power hit up top when the cams came on. I never liked my '99 m3 (s52) that much because it felt like a dulled down, tamed version of the earlier design. In a lightweight chassis like the E30 that 330+HP would be more than enough IMO.

Again, not trying to detract anything from your build, just sharing my experiences and opinions. A big displacement, high-revving V6 in an E30 is quite frankly awesome and I bet it'll be an absolute monster to drive!

True bro but the mods you counted will cost more thn the vq37 engine .. now you can buy the engine from junkyard for around 2000..3000 dollars with tranny and the s52 motor with machining and cams and labour charges and all the extra stuff you said will cost more thn 6k to 10k and also it will not be as reliable as unopened nissan motor and also if you want to spend same amount of money on vq37 lol the hp numbers gonna b crazy

But you dont need standalone for this engine ... Stock ecu is as good as any standalone for example most of 800 900hp 370z are running stock ecu so i can't think of anything else you need from stock ecu

You're correct that you don't need a standalone. But your statement quoted above is absolutely and categorically false.

Maybe .. cause i dont want anything else from a ecu and maybe you want some more from a standalone ecu .. Depends on you're needs

All valid points, but I had less than $3k into that engine. I got lucky and was able to buy a former weekend track day car that already had quite a bit of the mods done to it. All I had to do was make it a bit more street able as it was my daily driver. As far as reliability goes, the BMW wins lol. The VQ37VHR, as great as it is, is just so much more mechanically complex and has so many more possible failure points compared to an OBD1 S50. Agree that if you did all those same mods to the VQ you would have significantly more power, but you're also comparing a 3.7L to a 3.0L so that's kinda to be expected.

What would be a good cheap truck to swap a VQ37VHR into? I'm gonna do it when I win the crypto lottery. Honestly though I'd love to hear some suggestions. I think it would be super cool to throw one in an old ranger or S10 or whatever, especially if THE BULL sells full wiring kits

You don't need it for high hp cars but there is a big benefit to it. The only reason folks don't have one is because of the cost. It's 10k. Most folks on this platform won't spend that on their turbo kit much less what it cost for a proper built engine. That's why were are stuck in the stone age as far as development is concerned.

Old Datsun/Nissan hardbody would be cool. Besides this E30, they've already put them in a S30, Miata, and S2000. The DEs have been swapped into even more chassis, including a Sunny truck.

You're right, inputs and outputs are limited however take some time to study the diagram and you'll find it's 128 pins. Only exotic ECMs can take on the job and ALL of them require the use of the OEM VVEL unit. It would take a Motec PDM 30 or something along those lines to handle all of the inputs. which is why a flashed OEM ecm is the best it gets cost wise

Cheap american 4 cyl truck. Ideally you'd want a truck that companies make DE swap kits on since the mounts would work. The rest is gathering all the copper spaghetti needed.

With 37HRs hitting 400whp all motor, VHRs hanging in the 360+ cams, bolted allmotor and boosted setups only having engine issues we can agree that an exotic ecm might not yield that much especially since an exotic ECM would have a hard time controlling the Speedometer/triple meter.

The idea is to follow vehicles they make DE swap kits for since the mounts are the same height a VHR in theory will bolt up using DE swap mounts, softening the financial requirements of this swap.

I have a friend in south FL who VHR swapped a 03 Z with EVERYTHING from a 370z.

From an electronic standpoint the man spent $2k on recycled wiring and had a perfectly running VHR swapped 350z.

The issue is how much stuff the OEM wiring has and dissecting these to leave the just the necessary is just as challenging

From the BMW standpoint wiring might be a bit easier depending on how complete that VHR swap is.

I'm a firm believer the VHR dominates, their only downfalls are gallery gaskets and oil cooler. I compare the gallery gasket to BMW Vanos issues if it ever develops. Anything 6 cylinders making more than 300whp will heat up that oil, the VQ will just heat it up faster than most.

Once both cars are set up, engine failure would be most cost effective with a VHR. The BMW counterpart is starting to become a more exotic engine due to it's age.
