Sunny weekend means i got to start the 12a to 13bt swap

[RamoNZ]

Can\'t pm but I\'m willing to take any and all advice

[RamoNZ]

Well - I did it anyway..
 
FC subframe sitting in the car

 
 

 
 

 
Engine now sits nicely, and everything clears! I can now look to plumb the \'cooler too.

 

 

 
I got some new rims too - I think the black suits the blue.

That\'s gonna be one awesome car.... the amount of work involved makes my head spin though!

[RamoNZ]

I wish I had more time to spend on it, or even better an enthusiastic apprentice!
 
At this rate, I\'m not sure how much summer will be left when its finished!
 
Cooler is 450x300x75 core. Should be sufficient.

Nice install there i run the same cooler and it works well for the £60 i paid off ebay...
 
what turbo is that? and what ecu you going to run??

[RamoNZ]

The cooler was a bargain!
 
Turbo is an old skool KKK from a Jap Blitz kit, no fancy ball bearings or super adavanced aerodynamic compressors but as it is only a T3 1.00 (or thereabouts) exhaust housing it should boost nicely. Its not going to be a dyno queen, its all about the driveability.
 
ECU of choice is the DIYPNP - microsquirt based ECU that has the extra rotary circuits and a plug and play connector to go straight into the S5 loom I got. You still have to build most of it, but it takes the hassle out of doing the wiring from scratch.

Looking like its gonna be pretty wild when its done!

Not sure of your Megasquirt experience, but if you need some help message/email me I\'ve spent the last 3 weeks fiddling with my megasquirt set-up and with info off the american forums but there\'s a few tricks and tips i\'ve picked up that the forums don\'t mention.

[RamoNZ]

Yeah, thanks for the offer - i\'ll let you know when Im close!
 
I have been building the map bit by bit, but the biggest problem is that my engine runs the S5 NA rotors so Ill have to take it easy on timing.

This web site has a b7unch of usefull information. http://www.aaroncake.net/rx-7/megasquirt/ProgramMS1.asp
 
I basically started with his maps then tweaked from there. There are a few things I\'ve done differently though. One of the main things i\'ve done is practically halved the cranking pulse widths, so it may take a few turns to fire but it doesn\'t flood. which when the rest of your map is rough and its stalling lots is rahter useful! In regared cranking I\'ve also set the cranking rpm (in more cranking stuff) to 400rpm as my starter motor wasspinning my engine to 325rpm, and with the cranking rpm set to 300 that means once it gets over 300 rpm it thinks its running normally and not cranking and so doesn\'t give it the retarded timing and extra rich rfueling required for a clean start.
 
I\'d also highly recommend paying for the full version ofd tuner studio for its VE auto tunnig facility. Be setting the AFR target tables then just driving around it does the fuel mapping for you. As long as you keep an eye on the AFRs and make sure if its lean anywhere you richen it up manually and let the computer drag it leaner and leaner gentelly till its correct then its a veyr safe and quick way to get the fueling map sorted. It made very light work of my split map with AFrs of low 16s / high 15s in cruise and then 14.7 in normal conditions and low 13s when WOT.
 
Finally if the DIY PNP doesn\'t already I\'d add a 0.1uF smoothing capacitor between the 2nd CAS trigger input to the ECU and ground, really makes a difference to how well it can read the rpms.

Doing anything with the 12a and 5 speed???
 
is it for sale?

[RamoNZ]

12a is gone, gearbox is up for sale - 64k miles only..

[12at]

drop me a email with the price.. bo0557 @ gmail.com
 
does it come with clutch, starter, shifter and tailshaft etc ?

[captainbizzaro]

Any updates?

[CHC (RIP)]

Nice work ..... looks as if it\'s coming on a treat, nice wheels too.  Should be awesome when finished.

[RamoNZ]

Sort of updates - this was done a few weeks ago.. been struggling to find time lately due to work etc - The more I do the more I realise I have left!
 
Turbo fitted
 

 
Inlet manifold painted and injection gear done
 

 
Big brakes fitted at the front
