Mazda put a 1.8 V6 in the MX3

That's the one. It always interested me. I assume it is a one off or I it related to other Mazda motors. I seem to remember it had a impressive red line

Here's a larger version of one in a Miata with ITB's:

You're welcome.

always wondered how one of those little Mazda V6s would work in a locost or 7 replica

The 1.8 has a rod-stroke ratio of about 2.

I remember a friend who had a Siata, new. I remember the high pitch scream

don't know what happened to him or the car. GE may have shipped him and the car to California.

This right here...one of the most glorious sounding engines ever made...if only it were a more robust and reliable design. 2 liter Ferrari V12s are nice too...and more reliable.

Always was interested in the V6 MX-3 too...

High revving 2.4L or 3L v8s are nice too...

GT86 with Synergy 3L...

Though not small displacement I think the 1UZFE is my favorite though...inexpensive and can sound great:

GT86 with 1UZFE...

Ohhhhhh. Now that is nice. Sort of British roadster meets Italian. I really like that.

Is that a bolt in?

I know this is about small engines with lots of cylinders..

But when installing the 1.8l V6, why not go with the 2.5l? - they are the same size. At least that's what I understand.

Having driven an NB with a Duratec V6- it's a pretty nice engine to put in. No, not as powerful as a V8, but I do love the sound of the V6 a lot. For an Alfisti- I wish this swap was how easy an Alfa V6 would go into a spider.....

It was common to put the 200hp Japanese 2.5 in the MX-3. Direct fit and I know someone who had two of 'em.

I always thought the 1.8 sounded better than the 2.5, though.

There's apparently an anything-goes class of rally in France where there is a 2000cc (1500cc?) limit, and this guy makes 12 and 16 cylinder engines based on motorcycle cylinder heads/jugs.

I'm pretty sure the Toyota V8 before the 1uz was a 2.5 to 3 liter v8.

These little Mazda engines sounded amazing and IIRC had a zippy feel to them

OMG that sound

I have two of those motors and really need to get off my butt and put them into things.

Does anyone know if it is a direct bolt up to the Miata trans? How about bolting to a FC trans. I am getting really bad ideas of a turbo 1.8 v6 in a early FC.

Also does anyone know what the red line on a 1.8 is. I would imagine it should be able to really rev.

I doubt it would bolt to fc trans. Miata and fc trans are very similar except for bell housing and some other items.

Miata trans might bolt up. The pickup truck trans might bolt up too.

I believe the answer is no. What I have read about them is the bell housing bolt pattern is unique and not a direct bolt to other mazda gearboxes. There is long thread on Miata.net about connecting them to longitudinal Mazda gear boxes including rotaries.

I am convinced that I need ITBs on something at some point in my life. The sound!

I know there was some cam gear (pulley?) issues but what about the 3.4 V8 from the SHO? Is there any magic there?

In reply to RossD:

I think the cam sprockets were pressed onto the cams, this did not last. Pretty sure welding cured it.

2.8 liter Hayabusa v8

Changing tack a bit, what are the physically smallest and lightest weight production car V8s? I'm guessing the physically smallest could be a push rod and the lightest I assume is an all alloy unit hence I think they could be different.

I'm not counting a bike based unit, a pure race unit or an old old flat head, but something that could be GRM'd into a small light recipient or Locost etc?

The physically smallest is probably the V8-60 Flathead Ford. After spending some time helping debug my boss's dad's Solstice (the one that now has an LS3/TR6060 setup in it, and yes the chassis looks as though it was designed for this drivetrain) he was telling me about back in the day how he balanced a V8-60. They had no counterweights on the crank and shook like a sumbitch even though they were only 130ish cubic inches. He made and fitted counterweights for the crank and balanced it... then the owner had a buddy put it together to save money, and he Loctited the bearings, so it siezed, so he had to take it all apart and redo everything...

1uzfe. DOHC. Small for DOHC. 4.0L. And total weight is 475.
