So I started looking into engine swaps for my '73 240z. I have been leaning towards getting a front wheel drive vq30de and putting a 350z 6 speed behind it (using a 350z oil pan, clutch, flywheel, etc.). I know this won't make much power compared to a 350z vq35de but if I put a turbo on it down the road I'm sure it'll be more than enough power for me and it's a really cheap motor to pickup. I've been thinking I want to try to get megasquirt to work as I like the flexibility and ability to change virtually anything. It seems, though, that there aren't too many people running megasquirt with a vq of any type, is there any reason for this in particular? I know the vq35de is a very complicated motor electronically, but apparently the vq30de is much simpler. I suppose it would be a whole lot easier to get it running with stock electronics, so I may go this route but does anyone know if the ecu needs to be messed with before you can get it to run without all of the associated security parts like with a vq35 swap? Sorry if this is all over the place, I'm just trying to get some rough ideas as I have only been able to do some reading around online. I know a few people on here have done this swap and I have searched but I was hoping for a little clarification.
Now my other questions revolve around the drivetrain aspect of the car. I suppose I should ask this in the drivetrain section but I wanted to get an idea of what people are running as far as rear ends are concerned with their vq swaps. I already have pretty upgraded stock suspension and have silvermine motors stage 4 rear brakes, so I'd like to retain as much of this as possible. I like the idea of putting an R180 out of an Sti in as I can retain my brakes, control arms, coilovers, wheel stub axles, etc. However, if I am running a vq30det or a vq35de, with possibly up to 300 ft/lbs of torque, am I likely to be breaking diffs or associated parts with the Sti R180, or has this been done? I'd like something reasonably solid, even though I'm not gonna have LS1 torque and I won't be drag racing or drifting. However, from time to time my left foot may slip off my clutch pedal while my right foot may accidentally be pushing down on the accelerator pedal, and I'd rather not blow up my diff when this accidentally happens... My plan currently is to get the Sti diff but use CV's, as at least one member on here has done. I already have 280zxt outer axle flanges so this wouldn't be too hard to do, but I'm just not sure if this will be solid enough for this engine. I'm just not sure if I should be planning to go for an R230 or Ford 8.8 or something.
Hopefully this isn't too off in left field, I know it's much easier when there's more specific questions but if anyone has some general guidance for me on this that'd be awesome.
