Fazdarx_8's Top Mount Turbo Build
Hey guys, thought it was time to post a build thread. I have been researching and learning a lot about the Rotary engine, at first I started with the basic bolt-ons and decided that boost was going to net the most gains. I really liked the look of the top-mount kits like Speed Force Racing, Esmerils kit, and Turblowns kit. I then noticed mawnees build thread, how he built is own kit, as well as others and thought, its possible. I started looking at raw materials; spoke with a friend of mine who is a TIG welder, Eric Furgison, about fabrication and welding. It became clear that I could make my own kit. I decided to keep things simple and go with a log type manifold, it works and I can keep Radiator hoses and the OMP in place. So after gathering necessary parts the Fabrication began
the 2.5inch 304ss log snakes its way to a t4 flange where a T04E Divided 60-1 trim turbo is mounted sitting beautifully in the middle of the engine bay, to get ride of the exhaust there is a 3inch down pipe connected by v-bands this flawlessly mates to the stock exhaust. The external wastegate/boost control is handled by synapses engineering that is re circulated VTA. Currently set at its lowest setting
The intake charge travels to a modest intercooler then around back up to the throttle body, where a Synapsis engineering BOV is re circulated into the intake to keep the MAF happy, speaking of the MAF, I relocated it farther away from the turbo intake to keep turbulence down, I made a custom MAF housing that matches the stock housing perfectly, so well that when the car started for the first time it idled smooth, vacuum lines are handled by quick disconnects. Planning to run 10-12psi. Here are the pictures!!!
Soldering extensions for MAF (this is unnecessary if you take apart the harness there is plenty of wire)
Upgraded fuel pump to walbro 255
Fuel Injectors KG upgrades (4 uncapped yellows)
This is how it sits
So it took me long to post this cause I wanted more complete results
I was running 5psi, with Jeff’s base tune. later I bought rx-7 plugs
Rx7 plugs(NGK BUR9EQP)?? And datalog for the 10-12psi.
Its amazing at just 5psi, its so much of a rush for me that I can’t tell when the boost hits exactly it’s a blast and I am quite pleased with the results
I wanna thank

You are probably going to have problems with that MAF setup.
I would also worry about the materials used for the manifold, but only time will tell on that one.
You will want to change the orientation of the WBO2S.
The Synapse parts are absolute crap. You should reconsider them.
Unless you completed it after you took that photo, your fuel pump upgrade is missing a step.

this wasn't mig welded, and it wasn't tig welded with just one type of rod
your my tuner, whats wrong with it? I get perfect 14.7 afr's at idle, and about the same with cruising, boost it goes real rich, (Base tune from you)
like the parts them self or the construction/placement of them? from what I have heard they seem to be good, good reviews not sure of irontanuki's plumming issues but my setup is running smooth, have a good story to share?
yeah, lol the pump actually got swapped, got a smaller o-ring, melted the plastic bits, reassebled and put it back in the tank
