Well i am not going to use the diesel flywheel, as the diesel flywheel is to heavy as we all know, so i got myself a new flywheel made-up for my project.

My gearbox what i got I imported it from the UK, it is a Mazda 6 diesel 6 speed gearbox, but i also got myself a Mazda 3 MPS 6 speed gearbox, i will be using the Mazda 3 MPS gears.

Here is a picture of the Mazda 6 Diesel and the Mazda 3 MPS gearbox, i know that the starter is sitting on the wrong side of the gearbox, but i will over come this to.



And i got myself a Nascar clutch

Well i got myself a set of Pauter rods, and i bought a set of Wiseco Pistons of Matt of the mx6 forum, I am going to use ACL bearing in my build, and got myself a set of ARP L19 rod bolts to

Neville! Awesome posting. Good to see another modified Mazda FE in progress. Heavily modified - not just bolt ons.

I hear you on the length of time! 20 months, I think mines been close on that too now! Can't really remember when I did the initial teardown.

R2 Crank and the issues with oil supply I'm well aware of but it would seem you've covered all of your basis and common pitfalls.

Although I'm going the na route, I'm also looking at larger diameter valves, similar to those Ferrea items you've posted up - glad you found a good spring and retainer (and keeper) combo to match it all nicely.

Do you have any specs on spring rates? What was final deck height on the block after work? Still stockish? One has to stand back and admire the amount of meat we have at our disposal there compared to other motors.

PS: Glad you went Pauter on the rods - well worth the money invested there!

Good on you for the pics and posting, yes I heard Ryan was selling something at a steal - unfortunately not for my application, i've gone an entirely new route.


Are these direct towards my project? I'm not going stroker, instead i'm pushing the stock 1998cc to the maximum I can before it goes up in smoke :-) It's a test to see just how far I can push the motor in NA trim.

I can't give too much away on the build unfortunately specification wise (as its for my company and promotional reasons). What I can say is the parts list is 80% off the shelf with modification with the balance brand new items, designed from scratch.

The sort of brands I'll be incorporating span from Pauter all the way to OEM Toyota. Really a mixed bag to get the right combination that works for the project. I've got a big target to reach - it's going to be difficult - but possible.

I think the best to answer the above:

1.) Pauter or Eagle rods - undecided and budget dependent, if Pauter totally custom titanium piece (we deal the rods), if Eagle - something off the shelf modified for the FE DOHC crank

2.) Wiseco custom or off the shelf pistons with modification.

3.) I'll be running Clevite bearings with a specially developed coating we've been working on in Japan.

4.) Initially wanted to cut a set of billet cams but the cost outweighed the good parts of this. Instead re-cutting a virgin FE5A's (Sad to, but has to be done). I'm going for a moderate lift / high duration camshaft. It won't idle below 2000rpm.

All the best Neville - you definitely need to give me a spin when she's done, run-in and tuned.

PS: Forgot to mention this previous posting but the MPS box - it was something I considered with a good short ratio gear setup (for my own build) - the cost of those though. They are a bit pricey. If you have two and building one final box, is there trouble with the other one and the left over components? When you done let me know - perhaps I can still use 80% of the stuff with modification. (If I understood what you're doing there correctly)

Sorry - I misunderstood, thought you had two MPS boxes - apologies - this happens when you half read something and get interupted.

Will email you early in the morning.

Hi Neville, been very busy past week - please send through a mail to sales.at.toyamaracingspirit.dot.com

I'll get back to you on coating shortly, as stated, it's R&D stage, not ready for general public but more than willing to assist if you understand the risks.

Well Santa has come early this year for me.

No, those are Wiseco Pistons 86.5, those JE Pistons are a spare set of pistons that i want to use for a spare motor that i wanted to build, but the JE are 88mm and those are a bit to big, scared that the walls will crack under pressure.......  

Here is a picture of those pistons that are in my motor

No these are not the K20, these are for the Mazda FE Stroker motor, these are not off the shelf stuff, these were made up for the stroker, here is the Part number from Wiseco

Part Number: CA-00711-2326
Forging number: F6095XA1

Comp Height is 1.277
Bore Size is 3.4050 (I understand it as piston is 3.4020 add .030 for clearance)

Hope that it will help you, i have got the Wiseco Piston document that came with, if you need it i can send it to you..

I will measure the old Mazda FE pistons for you on Friday, and compare the the Mazda Vs Honda Pistons, and let you know.

Here is a picture of the standard pistons and a picture of the Je Honda Ka20 piston



The standard Mazda deck is 24.5mm and the Honda K20 deck is 19mm
hope that answers your question

wonder what the complications would be if you take the FE deck down to 19mm

4 pots off of which vehicle? Looks nissan-ish to me. Definite improvement in the stopping department coming your way - great choice.
