With the vortec V6 apparently you buy a Edelbrock intake and a Holley 500cfm carb and it bolts on. Buy an aftermarket HEI coil and dizzy and bobs your uncle.

Not the case with the L27 apparently. No provision for a distributor. From the 3 forums i read off Google everyone says no go. I find it hard to believe myself. I bet one of the early ones circa mid80s would be carbureted?

When I saw V6 Datsun, anyone ever done this? I thought VG right away. Where possible keep it Datsun but as there was no V6 Datsun, then a Nissan engine. Cutting the heart out of a Datsun and replacing with a 'big three' power plant is just wrong somehow. Like a 283 in a '64 Mustang, a 390 in a '70 Chevelle, a 396 in place of a HEMI 'Cuda.

My constraints are money. Not modifying the firewall. And must be V6 and carburetored. Im not dealing with ecu wiring, sensors, antitheft, and all that shit

VG motor with carb conversion
Buick L27 V6 carburetored
Vortec V6 with carb conversion

Those are my options so far. The buick is going to be the cheapest.

 With the VG, 3800, and Vortec being 90* designs, they may be a little more difficult to install due to the width. Based on your constraints and probably being the easiest to install, I would look at the following 60* V6.

 

GM 2.8/3.1/3.4

I would look at getting something from a Camaro/Firebird/S10 and swap on a 2.8 carb manifold from any number of GM cars/trucks and get a weber kit as the stock Rochester carb is garbage. Another nice thing is these were installed in a bunch of different models so there are plenty of options for oil pans, exhaust manifolds, accessory drives, etc. Plentiful usually means cheap too. There is some aftermarket support for these if you decide to want to hop it up down the road.

 

Ford 2.8/2.9/4.0

These are a much older design engine and the 2.8 especially is not known for it's reliability (heads crack). I believe the early 80's 2.9 were carbed but the 4.0's would need to be converted. Mainly found in Rangers. There is also a 3.0, but I don't think those were ever offered carbed.

 

Just a quick note on fuel injection, if you stay pre OBDII (1997/8) the wiring is fairly simple, even easier if it is a mid 80's TBI setup as they still used a dizzy. It also opens up a few more options.

 

BTW, my 1200 is about 28" between the strut towers at the point the exhaust manifolds would fit. The Mitsu 60* V6 is 23" at the valve covers and about 27" at the manifolds. I don't have something like a VG sitting around to see how much wider that engine is.

The 2.8 was the biggest piece of shit. I went to local wrecking yards looking for one. They all rolled their eyes. Now the 3800 is different.

The main issue with the 2.8 was bad intake manifold gaskets that let coolant leak into the engine thereby diluting the oil and eventually wiping out the bearings. If caught in time and better gaskets installed there was usually only regular maintence required besides the horrible stock carb. Got pretty good at changing intake gaskets and carb rebuilds on those in the day. By no means the greatest engine ever produced, but far from the biggest piece of shit. Personally, I would not use any 80's/90's domestic V6 engines as the japanese engines are far superior. I was simply giving info I believe the OP was asking for. Kinda limited with not wanting to cut and being carbureted.

Im really open to all options. The challenge is finding a carb motor and fitting it

With the blower sticking out of the 510 hood.

My neighbor has one in his morris minor

I'll put on chain mail and a dirt bike tire jock strap and drive it!!!!!

A lot of these domestic V6s you are mentioning would probably get whooped by a comparable car with an L18 in it. So...

It is surprisingly compact. Fits decent in a 1200...

It's your car, just don't ruin it.


This seems like an elaborate ploy to get me to say "I like the D".

Anyone ever take a Chevy S10 3.4L and put in a Datsun 1200 and make it fit without cutting the firewall?

 

Also, no.   :rofl:

 

 

If your car came with a manual transmission, you will NOT fit any transmission that works with those engines without cutting and rebuilding the tunnel at the very least.

 

If you're car started as an auto, you might be able to fit a medium-sized transmission like a KA or VG with minimal massaging. Anything bigger will again need cutting. Lots of cutting.

This would be so bad ass with three R1 carbs per side with long tube cross ram runners. I think someone cut down an L28 matchbox for ignition. Drool.

I've heard this wives tale before. It won't work. Trust me, I tried multiple distributors on mine and none could be modified to work well. 

 

In the end, just bought this. It's spendy, but dead simple...

I think a trans tunnel is not as hard to modify as a giant cutout in the B110 firewall no?

You shouldn't have to cut the firewall. V6s are one cylinder shorter than a 4.

Why? Both are cutting out old metal and welding in new metal.  ^_^

 

And as he said, you shouldn't be cutting the actual firewall for a V6 swap.

 

 

That's just an old chev V6 HEI distributor.

 

Actually, it's a brand new Chevy HEI distributor.   :P

 

Except the bottom is machined to fit a VG30E instead of the Chevy. If you wanted to make a customer distributor for a specific application, wouldn't you use an off-the-shelf cap and rotor to do it?

I'm not sure what it is that you're not getting...   ^_^

 

Davis Unified Ignition designed a whole new distributor specifically for the VG30E that uses GM components for all wear items so it's easy to service down the road. Not Chinese, not knockoff, not rebuilt, and not really GM. It just uses a GM spec cap, rotor, and coil.

Saw a good rolling shell on Facebook nearby. Might get the V6 party started soon
