Awesome pics showing exactly what needs to be done! Not as bad as I had thought. For the TB problem, I would think it may be easiest to cut the runners near the plenum and flip and reweld, if the centers are equal. Another thought would be to make a new upper manifold. For the distributor, it may be easier to adapt an EDIS setup, and leave the bare dizzy there for the cam angle sensor, if that is where it is on that motor.

yep that's great work mike!

even if the serena was sold in the usa, it might well have been only with slushbox
in europe they're only worth scrap nowadays

You could build a 90 degree elbow and install it between the throttlebody and the intake. Then the throttlebody would point into the recess behind the strut mount. 89'-up Thunderbirds with the 5.0 had a similar elbow, they used the same intake plenum as a 5.0 Stang but the throttlebody would not clear the Tbird hood.

OR

Cut 2 holes in the firewall and use an intake tube with 180 degree bend to get back into the engine compartment.

The 90 degree elbow is probably safer.
79' KC owned since 94' lowered 2", Z71s

73' standard cut to roadster, buick 3.8, tubbed, moons,wide whites, lowered 5" front 7" rear

77' standard, a/c, QX56s lowered 5"

78' KC utility bed

2 521s soon to be a KC flatbed dually

13 more that don't matter here

No problems, just opportunities:
* Use a $200 crank trigger system, no distributor needed
* Fit sidedraft carbs. In South Africa they sell aftermarker DCOE manifolds if i recall correctly.

That engine looks great in the 210 engine bay!

I've seen pictures before of people cutting the ends of the plenum off, swapping ends and using plate aluminum to weld it back together. It looks like the idle air motor would end up swapping places with the throttle body

I was thinking you could cut the ends off and JB-Weld them reversed.

didn't know there was a sidedraught intake for the ga!

that would look much cooler & cleaner than the clunky stock intake (even if you reversed the tb's)
but i'm guessing mike's gonna want to keep the oem efi intact

No need to keep the EFI -- you can trigger the variable valve timing with a simple RPM switch.

True but the ecu controls more thank the valve timing such as more fuel and advancing the timing. Look in to it some dumb hondar kids think just a switch will controls vtec but it also the ecu tells the injectors more fuel and the dizzy more advance + on a hondar their is an extra oil passage for the cams you donte wanna flip the switch and have it burn too lean.

This is something I've wanted to do for a long time... so this is good news to me. If you want fuel injection, you'll have to modify the stock manifold, find someone familiar with welding cast. For the ignition, if you want to retain factory injection, you're probably going to have to cut the firewall.

If I decide to go GA, I'm going carbs with megajolt, maybe even a single carb for fuel economy. I'd probably have the transmission ear widened instead of rethreading the block, but I'm excited to see just how simple you make it and the outcome. As far as the variable cam, I'd leave it on or off and tune for that.

You forgot to mention what you did for the clutch? Any idea if the input shaft and throwout bearing/carrier are the same in the LHD hydraulic boxes as the RHD cable boxes?

I have seen quite a few GA16DET builds and it's a common thing to port match and use the SR20's intake manifold though i've never seen it done the intake manifold for the RWD SR20 should be a good option if you port match it and provided it fits like the FWD SR20 one would, as far as the distributor goes id just get rid of it and go with a crank trigger like someone els was saying, that way you wouldnt have to cut the firewall at all, additionally =3 a turbo setup on that engine would give the engine some great improvements but one hurdle at a time yes.

Looking over Google now for info/pics on the RWD GA set-up. 

 

 

Interesting idea.

I'm here to bring this bitch back to life!!!!

 

Instead of the GA16DE I am going to use a QG18DE for my currently engineless 89 240sx (tasteless? who cares).   The 240 will be getting a different engine later, but I want this thing running again. 

 

I have a QG that I got from the local pick-y-pull yard.  The mouthbreather at the counter rang it up as a bare block (LOL) so I got it for $68 instead of $200+!  

I already have an intake from an E16 (?) which almost fits (flange and ports are like 1/8" off.  So I could use that to do a carb or TBI setup If I wanted (make an adapter flange). 

Another fun fact is the pilot bushing size is very close to fitting the KA transmission (the inside diameter).  Neat, eh?

The engine is small enough that the KA bellhousing will allow for the QG starter to be used.  Another plus is the QG's starter is oriented like a normal RWD engine's would be -- coming from the front. 

 

I'll snap some pics and attach later. 

 

Edit: I'll put pics up tomorrow.  This post might sound trollish but I figure the qg/ga is worth the effort since there are tons of them in the junkyard (esp. pick-y-pull type places).

I figure some people might want this as a swap option for older Nissan/datsun RWD platforms, so it's worth the effort.  Turboed, I figure it might not be the fastest, but still fun.  There are FWD turbo builds on the QG that get ~220whp on stock internals without problems.   IIRC the CA18DE exhaust flange is close to the GA or QG flange also (lots of of choices for turbo manifold on the CA).
