Hello all,

I started this build 3 1/2 years ago, so I have a bunch of pictures and stories, but Its a short crank 3 rotor, built with new parts from Precision Engineering in New Zealand, they supply the E-Shaft, counterweights, centre plate (with bearing milled in), flywheel etc, the irons are s6 and the housings are new FD with 50mm Peripheral Ports installed. Rotors are FC high compression NA, and clearanced and then the whole rotating assembly was balanced to 0.

And because a picture says 100 words lets see if i can upload some

 

Wow! That’s my dream build.. looks awesome so far

 

why was this not posted in the build section?

 

Hi, Sorry I didn't look that far into it, happy if admin wants to move it.

I have more pictures, but there is a limit to posting on the threads. here are some more

 

and more building the motor


this is the precision engineering centre plate that is supplied all machined up ready to go... im told these motors are good for 11,000rpm... not that i will every get to there.


slowly and carefully putting the sandwich together

one big hamburger ready to go

 

And more

 

Okay it seems I cannot upload anymore pictures... I will try again later.

I did write up a bunch of stuff under the pictures but lost that all somehow

 

nice! what rear end are you going with?

 

Awesome build! what trans are you going to run? Ecu? did you get a weight of the block of the short crank 20b?

I'm searching for a nice SA shell to put my 20B PP in right now. Glad to see someone else exploring this, I'll be looking for updates.

This site is terrible for uploading pictures isn't it

Can you give me an idea of what a short crank is?

 

Badarse. You'll have to post up skid vids when its ready.

 

Im running a 91 turbo trans, cut and shifted so the shifter comes up in the right spot, should handle 400hp okay
Rear end is stock LSD for run in purposes... I have a toyota hilux rear end with an ma70 supra clutch type LSD head, its a common swap for cars in Australia and New Zealand
ECU is a Microtech lt16 with Can bus set up so I can run my guages on a tablet
Weight of the motor alone i didnt weigh it, but the car weighs 1984.42 Lbps, or 900.12kg with the motor in and the interior out...

A short crank is an e-shaft designed specifically to use a normal 13b iron as the intermediary iron instead of the mazda factory thick iron... it was developed at a time before all these after market guys got into CNC and wot not when mazda werent producing the replacement thick irons. Also it makes the motor shorter by 20mm or so, so better to fit in a tight engine bay.... I have to say its a good fit in the engine bay of the 83

lets try uploading some more pictures

 

Still wont let me upload

 

 

Looking great! pretty awesome solution for the oil pan, I like the creativity.

 

Man this is like the ultimate FB goal, keep chugging along with it!

 

The want is too much. Dream build!! Keep at it.

 

 

 

 

 

May not look like much, but it took 3 days...

 

^I bet it did. Looks great!

 

 

Once the extractors were done the rest of the exhaust went on in no time at all. these are specialty rotary stainless packed units so they will last longer than the stock fibreglass units

can see mt racingbeat suspension upgrades

2 v bands on a 3 inch thick wall mild steel pipe should in theory make it sound nice. But can always beef up the muffling in the mid section easily too
