Your ideal powertrain swap?

The power it has is directly related to how much voltage and amperage it's fed... It would take an aftermarket controller, but I imagine that unit could handle much more than it was intended for...

Powertrain from the 2017 Acura MDX Sport Hybrid:

Acura Wants To Beak Free With 2017 MDX Facelift

This rear drive unit has more power than the Toyota/Lexus rear axle, and twice what the Arcimoto SRK spec is (although I can't find a reference). The torque vectoring is a big deal, at least to me. The SRK has it but the Toyota MGR is an open diff.

The donor vehicle should be the oldest, weirdest VW-powered whatever ever. Today I'm partial to the front-wheel drive Tempo Rapide Kombi:

I can get behind this. In my spare time I used to doodle VW buses powered by modern Honda / Toyota engines.

Geo Metro XFi drivetrain in a CRX!


Some of the swaps I've thought about:
VW TDI ALH engine in an S10 or Ranger
Yaris diesel engine and manual trans in a Prius
CRX HF or Civic VX engine in a Civic Wagon
Cummins 4BT in an older Chevy pickup
Nissan LD28 diesel in a 240Z/260Z/280Z
Metro 3-cyl in a Samurai

Purely for economy, I could entertain doing a Mercedes OM616 diesel in an old Ranger like I used to drive, but for all around performance, I'd almost rather a 4.8LS/T56... Plenty of power, and probably decent mileage with proper gearing...

How close to a stock drivetrain are we talking?

I am quite fond of Honda offerings, but their previous hybrids have missed the mark a bit and the new ones are for heavy cars.

I would like an L15B or R18A1 with titanium intake valves, a small centrifugal supercharger, and something like GM e-Assist (not particularly difficult to retrofit) with lithium ion batteries.

It would be tremendous fun at 8000rpm with a manual transmission, and extremely fuel efficient

I don't think staying close to stock or even in earshot of it is a goal in this thread.

Well see that opens up maybe too many doors haha, because you can use stuff that isn't really mass produced yet. For example I would want an electrically assisted turbo, which only F1 cars use, or a CVT drive turbo.

My ideal would be 4 cylinders, 86mm stroke or shorter so it can get near 9000rpm, using the lightest/smallest block that can be bored out to around 1.6L, with switchable cam profiles e.g. VTEC so it can have an Atkinson cycle mode. Add a mild hybrid system, and if the car is a little heavier add a small amount of boost, no more than 0.4 bar for minimal lag.

DIY EV fun (aka powerful) drivetrain in a tastefully aeromodded 280Z. I've wanted to do this one for quite some time. However, I can't justify building an EV summer car that I can only drive half the year.

This one is even for sale right in my town...

With the Tempo's mid-front layout it would be like a ninja mini-Previa.

Accepted practice is a Subaru swap; but the tidiest inline-4 install I've seen was this Pinto 4 in a dune buggy:



The buggy has essentially no engine compartment. The battery is laid on it's side and the muffler is tucked right up against the block. Without the boxer heads there is a lot of opportunity for diffuser, internal ducting and maybe a teardrop pant around the engine block.
