That is goona be one sweet turbo setup with the evo parts. Like how chopped up the manifold and welded the B5 flange. Nice work man!!

So other than comp ratio why does the b5 make more power?

Also can you guys recommend where to get oil feed and coolant? Is the port by the disty oil or coolant?

Seeing as this is running a MAF this "should" be the same block as the B6DE. Easy way to check is on the exhaust side of the block there should be two oil passages that run down the front, top to bottom. They are in between cylinders 1-2 and 3-4. If it does not have them you can still use a B6DE head, but you will have to put plugs where these oil passages are. Many 323 guys have done this to the older 323 B6 and B6T motors. The ports on the heads are so much bigger, the flow is increased drastically. Comp ratio is the same in both motors.

I tapped my oil inlet to the oil pressure sensor on the back of the engine. And tapped my coolant line to the in and out of the throttle body. If you can find one the coolant hard line from the pump to the heater core from a BPT it will have an extra line on it for the turbo.

Alright thanks for that Josh. I'll maybe weld my own outlet onto that coolant pipe then.

MEGASQUIRT RUNNING THE SHOW

I reflashed the firmware, grabbed a tune off miataturbo forums and boom RPM at last!
Next dealt with spark issues.
Then configured for fully sequential fuel injection and was running!

Still need to wire in:
IAC
AC
Fan control
Launch control

Thinking of picking up Rx8 yellow injectors 425cc, fair enough? I want high impedance for minimum hassle.

Picked up a free flange from my local exhaust shop for a chunky 3" downpipe I have 3" flexpipe ready to rock and elbow for the turbo on the way. Though it'll be going into a 2.5" decat... followed by 2.25" exhaust... for now anyway.

Shopping list is getting short, thankfully.

How difficult was the Megasquirt installation? I have the exact same RHD JDM vehicle and am about to install a MegaSquirt II PCB 3.0 shortly. I would appreciate as much information regarding the process as possible. I am also running a turbo setup.

mazdamx3bds - I will do up a list of all the pins I have found out soon and post it here. A lot of the miata 1.6 stuff crosses over which helps, the pins do not, but the logic does.

OTT 3" DOWNPIPE TIME

Take this:


and turn it into this:





I only had 3" SS pipe left, and it leaves room for upgrading the rest of exhaust later, so there you have it. I didn't have a reducer so just made slices and bend them in to reduce to 2.5" round the back. I have to say what a pleasure it was to make compared to weaving one under a v6 crossmember with the KL turbo. That massive gap in the alu sump makes it so easy

oh and it's now road legal and my daily driver!

I think I've finally decided the AC is going to go. Northern Ireland is baltic enough and it will make intercooling a LOT easier.

looking good!

Its so pretty

oh man that is so cool!

Progress has been slow of late. Had the car stolen by scumbags, fortunately it got chased by police and soon recovered with fairly minimal damage - door frame dented from prising open, ignition wrecked, steering column lock broken, plastics destroyed. I've since replaced the ignition and steering column, big thanks to Jason aka jayom for parts Many security features have been added also.

Today I repaired the damage around the door frame, paint ain't great. However looks a lot better than a crowbarred frame! I then waxed the whole car for the first time. Came up pretty decent. Still need to lose those bump strips. I also replaced the door seals on the DS which were also damaged from a break in. Much better

Also installed my lovely protegé steering wheel, classy stuff. Did require butchering a simple clock spring onto it, but easy enough.

Nice clean mx-3, I like it a lot.

i'm glad the police were able to recover the car, that wouldn't have happened here, our police are useless for theft

Yep^^^ same here. Cops would have called after they had it impounded so you would have to pay the fees to get it out.

I had to pay £150 to get it back from the recovery depot. I was fortunate that there just happened to be a police car on the stretch of road they took.

Thanks guys

Toad cat 1 alarm fitted today! Had it fitted by a pro to get the certificate for insurance companies.

Nice to have RCL again. Doors lock after 10 seconds for antihijack. He also hooked it up so the interior light stays on until I turn the key So theres like 4 levels of security on this car now
