ie if you put the B6T in the NA6 body, why cant you use the B6T ecu...

Is there any way you can put a B6T or GTX/GTR engine in an mx5 NA6 body WITH all of the accessories, ie intake, exhaust, ecu?


SImple answer is no.

The B6T ECU needs the engine to be running a dizzy rather than the CAS of teh mx5.

The dizzy cannot physically fit on teh back of the engine in an MX5 shell.


thats right.. to fit in the dizzy you have to cut in to the firewall and it will be a bitch getting it out if there is a problem with it.. PLUS cutting in to the fire wall to fit an engine I don't think will go to well to the motor reg

Sean is absolutely right. Here's a (crappy) piccie of the engine I put in my mx still in the half cut to illustrate...

Notice the amount the distributor sticks out the back (right side in this photo) of the engine. It can't fit without making a very large hole in the firewall. So you have to fit the mx5 coil packs and CAS instead. This is fine, but it takes two ecu ignition signal outputs and the GTX ecu only has one for the dizzy. Therefore - aftermarket ecu.

Also you can't fit the GTX exhaust or intake manifold in an mx5 as they both face the wrong way (see piccie once again).

The good news is that if you get the same capacity engine to the one you already have (ie B6T for B6 or BPT for BP) then everything save the exhaust manifold will bolt straight over.

Sabretooth did an excellent write up on this a while ago here - http://archives.aus-cartalk.com/viewtopic.php?t=10144

This is what eventually inspired me to do mine... :D

I can't rem what the requirements were off the top of my head. they're at work.


Fairly sure you can only use the 5 or so authorised engineers.

I had Doug Potts at Wayville do my Skyline


Edit

Oh, and I know tons of people who've bought modified cars from interstate that have been told to piss off by Regency when they bring it in for an identity check, notice its modified then order a full inspection. Regency doesn't always accept stuff that the approved SA engineers pass, and they certainly don't always accept something thats been passed by an interstate engineer and rta


My plan for when my car is either turbo'd or supercharged... Make it look as factory as possible and claim "It's a Cubman, they were all like this" :lol: :lol: Could work... Even the guy at the spare parts desk at Mazda today didn't know what a Clubman was and couldnt understand why I wanted an air con belt that didnt do power steering aswell
