Few pics of my project
S5 motor from Shane at Rotaryworks. GT40 from NYT. Tial gate, rons racing radiator. Space is extremely limited, but I think I did ok with what I was given. Manifold was put together from mcMaster carr stainless elbows, RB flange, and a T4 flange. Total manifold cost $65.00 I tig'd it up last night, looks great. heavy, but I don't forsee any cracking in the future! Wastegate discharge will go behind header and follow DP down, atmosphere discharge unless it's to noisey. I've done some dyno tests in the past, and picked up 18hp at the wheels as a result of atmosphere discharge. I'm wondering though if I bring the gate into the DP further back, if that will negate the benifits, and keep things a little quieter.
3" is all I could fit, I don't see how 3.5" would have any chance unless I did some crazy through the firewall out the passenger dorr setup, and although I'm hardcore and like the idea, I wonder if I got stuck in the left lane how much a cop might like it if he pulled up on the right.
Purpose of the car? To have lots of track time, aka "track *****", and drive on the street when needed to provide entertainmet to myself and scare the crap outta others.
Dunno what color it will end up being painted, but for the beginnings of it's life, the exterior will be in epoxy primer, so flat black here I come Next week the engine compartment will be painted in the stuff, and whenever it's time to upgrade turbos or have BDC port it, we'll paint the engine bay along with the car. Always wanted to have a flat black car....
Beginnings of an interior:
Since I'm 6'4", and sit way back, I had a problem. My knees and the steering wheel wanted to occupy the same space. Solution? Go down to the roundy-round store and grab some steering shaft and brackets, along with 2 heim joints. Problem solved. I machined off the spline on the stock shaft and turned it down to fit inside of the new steering shaft. Welded it in, now the new steering shaft slips into the steering u joint like factory. Cut it to fit, make a door bar, whala...now I have steering up in my face and my legs can sit flat and comfy, the way you are supposed to drive!

More pics in the next few days. I'm ready to do some rails, I just need the bore size for the injectors. I'll do a set for you, np. I need more fuel rail blank, so I might end up making a few sets.

Theo, PM'd you. NYT, The stock rails un-modified require metric adapters that neck down too much IMHO. I know plenty of guys run stock rails, but when you are trying to push 70-80psi of fuel @65gph, the fittings are a major restriction.

OK, guys, I've been wanting to put a rotary in a Miata for a while now, but had been told that a major obstacle was the higher relative position of the output shaft of the rotary vs the stock piston engine. Was I mislead?

It took me ~8 hours of work, including thinking time, to hang the motor and trans. Cutting the subframe a bit and box it back in, and make an oil pan took the next part of the day. It's really not that hard. Car ought to handle even better than before, as the motor is MUCH further down than a stock BP motor.

I like Boostcoolers on Ebay for very reasonably priced Spearco Bar&Plate ICs. I think ~300.00 will get you one of the proper size. I have a 33x10x3 in my FC, cost 500.00 delivered. Carl
