96 VR4 ECU





Now to find an Engine Harness. I think this would be the easiest way. And save the flashable ecu stuff for later. Pretty sure I'll have a hard time finding a 98/99 harness.
I also found a guy selling a 95 harness. Should this work with this ECU? OBD Hybrid was 94-95 right? Would either of these work or do I need a 96 harness for this particular ECU?
Also, does Fed Spec/CA Spec matter for mating the proper harness with this ECU?

Wow, I've been slacking....

But, downpipe is here


Just have to figure out which route to go with the ecu/wiring.

You'll probably need to add a bit to the downpipe if this is going on a 6g74. I had to add about an inch to front pipe and 1/2" to rear. Mocking it up on car was better than on engine stand. Only $60 at exhaust shop.

The aftermarket downpipe I have now fits fine. Good inch or so clearance. Spacers wont be a problem if needed

Ok, so that's not the last part needed, but the last major part I should say.

First I'm going to start with oil return fittings on the oil pan. That way I can go ahead and redo the gasket and get some good testing for leaks on the fittings and my gasket job before complicating things. Any suggestions?

Seems to be ton of aftermarket options. I'm thinking something I could just drill a hole in the pan, gasket in between and bolt it onto the pan from the outside. I plan on using custom braided lines. Using the stock 9b's, what type/size of AN fitting should I use. And suggestions for a good way to cap it off in the meantime?

Suggestions for oil feeds also?

-4an oil feed lines

-8an and -10an are popular drain options.

Are you planing to run 9b's on a 6g74? I thought they were more of a restriction on that engine.

[sketch]

are you going to be running the stock 10:1 pistons?

[n2nsanity]

Planning on running 9bs on 10:1 at around 12psi for now. No idea what the future holds.

Sketch, think those sizes will also work well on possible future upgrades?

Any suggestions for putting the drain/feed fittings on now and capping them? I was thinking of installing the lines also and somehow capping the end of the lines instead of at the fittings.

i've never heard of anyone using anything larger than -4an feed lines
if you're looking to future proof, i'd go with the -10an drains, it's what i'm going to do when i get around to building my 6g74 block.

a cap or a plug would do the trick for you
