No one has done a swap like that. Mostly due to the fact that the combination doesn't really make a lot of sense to put in another car on purpose...

yeah i dont get it. i didnt think mustang had a 3.8 v6 through the late 80s. thought it was either 4cyl or v8 but i could be wrong.

either way, you could make a lot more power with a 5.0 or 350 for probably similar or less money.

For the price of a setup and fabrication like that, you can build a proper 13BT and have the satisfaction of it all bolting into the chassis.

If you want a V6 mustang motor, get a V6 mustang... I just don't get the V-whatever into Rx7's. Start with a similar sized V6/8 car Like a fox body mustang. No need to waste time and money doing the swap.

the 86-93 mustang either had the 2.3L 4 or the 5 slow... they didn't have a v6 mustang until the "new" fairmont err mustang came out in 94?

http://en.wikipedia.org/wiki/Ford_Mu...2.80.931993.29

you do know those v6 mustangs all blew up under warranty right?

like sen2 said, totally pointless swap, you might as well find a v6 mustang...

Holy mis-information! The Essex V6 is one of the most common engines in Fox Bodies. I personally owned an '84 LX with a carbureted 3.8 [pile of ****, fyi], and have worked on countless 3.8 Foxes from 1983 clear to 1993, though admittedly a couple of the newer ones were swapped in.

http://en.wikipedia.org/wiki/Ford_Es...gine_(Canadian)

If you insist on using such a poor platform, at least get a leg up on power and get the F150 4.2 shortblock, toss ported 3.8 heads on it, get a huge cam, lightweight flywheel, spend a whole bunch of money getting a T-5 or TKO to fit behind it, and then start breaking N/A diffs and stub axles like they're toothpicks.

That just really seems like a "why bother" type of thing.

been saying the same thing locally.

Why go through the big trouble of swapping a foreign motor in and going for a crappy 200hp v6?

My lm7 with just a cam will put out as much power as the turbo'd v6.

Just because the motor is cheap, doesn't make it a good swap. That's like putting a CA18 into a FC just because you can get the motors

So, heavy and lots of RPM. Why in the hell are those positives?

I'll take my aluminum block and making power from 3500 RPM, thanks.

I'd rather take an alluminum block SR20DET over a CA18DET any day.
