Is there a Mazda six that is essentially the Miata engine in a six cylinder version?
I have a Triumph GT6 that needs a plan, restore, modify, or sell.
Drove the '95 Miata 1.8 a little recently, pretty peppy engine and actually enough HP to be a reasonable choice for the GT6.
But putting a 4 into a car that came with a 6 just seems too wrong. :ack:
A six cylinder TC version might just seduce me to the dark side? (Japanese engine in a British car = Heresy!)
Maybe there is an "American" brand badged version? :P
With a modern OD five speed it could be a pretty sweet driver without being the loud obnoxious tire spinning street terror that my current Trick-6 is intended to be.
I would probably want to shed the F.I. and other over-complication if possible.

Was a random thought.
Seems the answer is no. :(
But the Toyo Supra six is not too hard to find. :)
They even turn up in junk yards or cheap on CL, with high mileage.
Supra engine looks a bit wide up top?

Don't think so. Mazda 6s tend to be Vees.

Best donor options I can think of:
-Datsun 280
-E46 BMW
-Nissan RB engine
-Toyota supra (M or J)

Are you philosophically locked in to an I-6? Would a V-6 work for your plans? I doubt that you'll find any modern I-6s that are anywhere near as compact as the Triumph unit. There are the Nissan L series, but they're SOHC, and still rather tall.

Another possibility might be the Suzuki Verona. 2.5L I-6 powerplant. Kind of rare here in the States.

Being "Rational" :shock: for the moment I've listed a couple of projects to the for sale list.
If I cannot get what I want for them I may pick this idea back up later.
NA Supra engine might be a good choice as a Supra would have a manual trans and the diff needed to upgrade the GT6 rear, so nearly single donor. :D

Seems not hard to find, not even terribly expensive.
No dimensions that I could find, no weight.
What manual trans to use?
How hard to put on carbs instead of EFI?
Wonder what power might be on Webers?
Do not need 300+ hp but always enjoy a high red-line. :wink:

Why does that strike me as Heavy, Weird, and Complicated?
Maybe because I've had Volvo's and they do tend toward heavy, 5 IS weird, and turbos IS complicated?

Having no one available to help with projects is forcing me to reconsider what I build.
I've become pretty clever at one handed actions and have bought several tools that help a lot, but when two people are really needed a one man band sounds sour notes and is not fun!

Just remembered, VW makes a weird little single headed V6.
Emphasis on "Little" for an easy fit.
Not sure if they can be configured longitudinally and adapted to a normal trans?
HP, particularly if simplified on Webers instead of FI?

Need to get this idea out of my head, I'm going to re-arrange some cars!

why would you want to junk all that fuel injection and engine management for a very expensive carb setup and have to fabricate an intake manifold plus modern engines don't have anywhere to fit a distributor and if they do have that facility they won't have any advance and retard weights or a vacuum can.

the engine management system doesn't know its now in a different car and if you buy a donor car you have all the parts and wiring.

i ran my duratec on the stock computer for 5 years and even though i now have a blower it still uses the original computer.

you will be surprized how easy it is to keep the original engine management.

when i built my car, i was so confident that it would run that i never had an operating key until it had passed state inspection and was registered then i took it to a locksmith and had a key made and programmed in, turned the key and it ran and idled.

my friend just finished a 55 dodge pickup with a 2000 durango chassis and drive train, all the factory pieces were in the donor, he just transplanted them into the 55, it started on the first revolution, not after a couple of goes, instantly.!

Okay, not sure of ratios or availability, cost?
So it "Could" be done as has been done, sort of.
Wonder if you could get by with two DCOE's since the engine is short and a custom manifold will be needed anyway?
REALLY need to stop this, let it be inspiration for the next guy! :BH:
I can accept a German engine more readily than Japanese since the Arnolt/Bristol set precedent. :wink:

'Cause I am not a fan of electronics over tradition.
Have read several threads on the frustration of figuring out what wires to delete.
No dizzy ignition is not that hard or expensive, been around a long time.
Will have it on my Weber carb Alfa, but will also have Webers.
Also the EFI setup's are BULKY, and now also made of (EEW!) plastic!
Cannot see all that electronics being simpler than a set of Webers, which are not really that expensive, particularly compared to some of the ECU's and supporting sensors.
If I did it the ECU and FI would go to the trash, maybe I'm the only one that sees it that way but that is who I am.

Now, what is the VR6 redline?

sorry to have rocked your boat there Richard, but in for a penny, in for a pound, then why would you want anything in it other than the original engine?

a VR6 is soooo traditional.

as far as which wires to delete, keep them all and the plugs on the original wires will only fit on one sensor.

believe me it is so simple to do you will not make a mistake, just lay the harness from the donor on the engine and the plugs will almost certainly line up with the right sensor,

in fact don't even remove the harness from the engine, leave it all the wiring connected and just supply a bat pos to the original donor fuse panel and the various grounds to the chassis, keep everything else connected and it will start, run, idle and anything else it needs to do all by it's self, then if you feel so inclined, just remove fuses from the fuse box for the redundant circuits, if it stops the engine, just put it back.

the redundant circuits could be used for any other things you would like to run.

all of this comes free with the donor as opposed to spending money buying the carbs tuning the carbs making the parts to install the carbs and the purchase of a complete ignition system, a distributorless ignition, must have the parts that the donor engine already has, the only difference is the injectors and fuel rail, a coolant temp sensor a map/maf sensor an O2 sensor and a fuel pump, all of which you have on the donor.

a wokrshop manual for the donor will have a complete wiring diagram of the car which will become a complete wiring diagram of your finished project.

my friend with the 55 truck kept badgering me that when he came to start it i would have to go and get it running, well all i got was a phone call to tell me he would be round in the truck later as it was up and running with no problems at all.

the bonus is that it will work every day hot or cold wet or dry on any grade of fuel, no messing with re jetting and a thousand or so dollars in your pocket.
