Hi,
Yet more work done and no updates, sorry.
Everything will work as it should apart from the ABS and traction control. I would like the abs to work but I'm old school so my foot does it instead, maybe Craig has an update for it now? I don't know.

Yesterday was a good day! I made the heatshield for the starter motor and bolted it on, all planned for cranking it over. I had completely stripped 3 starters and chose the best parts to make one good one and it is in very good condition, it's the uprated version, more grunt than the standard one.

Flywheel and clutch in, works as it should. I turned the key and spins over fast! I have a video but it's too large for this site. I did this about 7 times for about 10 seconds each, I then went under the car to feel the starter and wiring, cold, virtually no warmth in it at all.
I'm very pleased with this as I read speculation that this starter motor and flywheel set up was not "man enough". Not true. Someone also said leaving the standard klde flywheel on and move the starter motor in by 5mm??? They have never seen the 2 flywheels together or how the starter is bolted in the gearbox. There must be at least 30mm in diameter difference. The important register for the starter is the hole the motor fits in to, not some bolts holding it on, it needed to be done properly, you would need to create a new hole 15mm in on radius.

Anyway, not long now, I'm having the airbox being made now, single wiper arm mount is made, all the plumbing is done, just the trigger wheel to bolt on and small tidy up jobs. I do hope I'm driving it by June, it would have been done already by life gets in the way.

Tease! Still looking forward to actually seeing a v6 one on the road!

That looks brilliant, thanks for the pictures, the throttle bodies look very cool, are you going to build an air box for them? And Is that an electric water pump? Thanks, well done on the conversion.

I'm having the airbox made and will fit like a glove in the bulkhead, well with room to move around. It's going to have a panel air filter that will sit above all the trumpets. Are you referring to the motor next to the battery? It's a vac pump to run the brakes, well, just an idea because I don't think there will be enough vacuume from the throttle bodies. I have 6mm "T" pieces for each and I need to run vaccume to the fuel pressure reg, map sensor for the ECU and LPG and crankcase.

Hi

Firstly, great looking site.

Secondly - the gearbox being used here, is it a M15M-D? It looks like it, but I'm no Mazda expert.

Also, what was the donor vehicle to provide the v6? Apologies if I've overlooked the answer to both questions in the thread!

Hi,
The gearbox is the standard 5 speed RX8, I chose it because the 5 speed 5th gear is taller so the rpm will be sensible at motorway speeds, the 6th gear is about 450 rpm higher.
The V6 is coming out of a MX6, this swap is happening in 2 weeks!!!! It's booked in for mapping and dyno runs on June 3rd!!
Watch this space!

Excellent, keep the updates coming!

How much of a nightmare is/was the wiring side?

Any Mazda gearbox gurus on here? I have a R15MX-D gearbox. Any idea if I could use an RX8 bellhousing and adaptor plate to fit the KL to my gearbox?

Mazda seem to like changing things ever so slightly to make swapping a nightmare...

Thanks

RX8 does not have a bell housing, the "bell housing" also forms the front half of the main case so if you remove it you expose the gears. Easiest way is what ClaireToo has done and also Freddy 686868 (on Turbosport and ebay) is doing for a range of engine and that is to have a flat adaptor plate cur to joint the RX8 box to the Engine.

Looking good! Wondering what you're planning for the injectors/fuel rail for the throttle bodies? I'm about to look at this for my Zero but unsure if I'm going to run a central rail like it looks like you are or flip them to the outside (spacing issues on my current adapter plates)

A work colleague had an RX8 as a company car for a while. I drove it a few times and have to say I found it somewhat lacking in whoomph. I'd like to see what it's like with a 225bhp VAG motor instead - driven a few cars with those motors and found the motors very pokey indeed.

Yeah not too well, it got really good power and torque but far too rich, you can smell the in burnt fuel on idle. The injectors were working so hard that 3 of them poo themselves after 70 miles or so but only 5 blasts at gunning it. It's going back this week.

The mapping went well! Selling it now.


This project has been a real joy, countless hours and many tears and sweat getting this beauty right!

-The V6 has come from a MX6, 2.5L.
-Dyno at Jam Sport with huge torque and power.
-It has 6 throttle bodies with carbon trumpets.
-Stainless exhaust from the heads to bumper.
-BMW M3 drive-by-wire for the throttle.
-Powder coated cam covers and sump.
-Carbon affect on the front cam belt covers, and other plastics under the bonnet
-All pipework and exposed aluminium has been nickel plated.
-PZ powder coated wheels and springs
-PZ dampers, dyno checked at Bilstien.
-Calipers were sand blasted and completely rebuilt, painted, new discs and pads.
-Single are wiper blade.

It does pain me to want to sell it but I could use the money I've spent on it.

Hey,
I'm half thinking of breaking the car if it's going to be too difficult to sell complete. What engine are you using? I could sell you mine complete? All the adapters, sump, inlet, the lot!

Thanks but I'm too far along with mine to start something different, I'm using the 3.0 out of an s type. Should be closer to about 270bhp so I'm gonna keep going this direction, thanks anyway

I looked at that engine but I found to 50mm too wide. Do you actually have it in the car? Do you have it forward of the clutch master and water pipes? How about the subframe and steering rack? I found all of these are in the way so it would be interesting to hear how you have over come this? If I were to do it again I'd put a V8 in and have a new subframe built and use the standard ECU.

Ok, no I haven't sold it yet, the only interest I get is people asking what I did to get it to fit so they have info to do their project.
I get about 2500 views in 2 days and about 60 watchers. I probably should advertise somewhere else as well.

Ah that's a shame, I can't help with the advertising as I never sell cars, in the past have either scrapped or traded them in against something else.
