Big update. I finished the wiring for the adaptronic and LC-1. I put the gauge in the air vent, but the boost gauge I have is slightly too big to fit :( I also bought some 550cc RX-7 injectors. Unfortunately they turned out not to be the plug'n'play ones but the Adaptronic can control them anyway.
Then I had to put the turbo oil return in the sump. I didn't have the tap required and I really don't like the idea of tapping the oil pan while it's on the car, so off with the sump.
I made a steel fitting which is threaded to go on the inside of the sump.
My turbo oil line arrived a few weeks ago, I finally got to install it
I had this intercooler which I bought for another on-going project, but it fit so perfectly in the MX-5 that it's staying. I haven't done the bottom mounts yet, I think I'll attach it to where the tow hooks are.
Slightly overkill for the power I'm chasing
I installed my yellow speed racing dynamic pro sport coilovers
I managed to break a few studs in the exhaust near the catalytic convertor, so today I started making a full 2.5" stainless exhaust.
Here's the free muffler I picked up from the scrap bin of the local exhaust place. It's a "Max Racing" brand which looks to be a pretty good JDM brand (http://www.maxracing.co.jp/
2.5" 316 stainless tubing for the exhaust.
^There's also some 2" stainless I bought from a scrap metal yard to do the intercooler piping (I'm not good at welding aluminium). I bought a 200 cpsi metal substrate catalytic convertor on ebay. Who knows how well it filters the gasses, I'll be running E85 for the emissions testing.
So today I spent all day cutting, adjusting, and tacking together my new stainless exhaust. I was having trouble getting the muffler at a decent angle out the standard exhaust location, and then it hit me. Center exit exhaust! First I had to cut the bumper, after using a laser and careful measuring to find the centre of the car.
And here's the (almost) finished product.
Lobster back bends
much cheaper than mandrel bends and good welding practice. They don't flow that much worse than mandrels and are certainly better than crush bent pipe.
New exhaust vs stupidly modified stock exhaust
Let me know what you think. Next up is to make the downpipe as soon as a few parts arrive, then intercooler piping and finally TEST DRIVE!
I just worked out the total cost of this 2.5" turbo back exhaust
It's less than $250. Not bad for a 316 stainless system, I thought
