IR Performance Shop Car Build
Hey People, You guys might recognize me as Andrew over at IR Performance. After much thought we have decided to finally rebuild my RX7 to IRP Spec and make it our official demo car. I wasn’t too happy with the build done by the previous owner even though it was a 500+ HP car. Too many corners were cut to my taste and decided to build this car correctly. We are going to use the best parts available on the market including everything IRP has to offer from our IRP Motor Mounts to our IRP EFR Manifold running the Borg Warner 9180 and everything in between 
Our goal is to have the car ready by DGRR, but it will vary on our current work load and projects at the shop. This will not delay our customer’s builds as this will be an after hours project. This thread will show our level for attention and detail for all our customers, not just for this build. We treat every customer's car as if it was our own.
The turbo arrived today and the car in the background is my car that is going under the knife.
We will be sending out the rotating assembly to get race balanced and rotors lightened from our good friend Chip over at ChipMotorSports.
Today I started porting the motor with our IRP Half Bridge template. I will keep updating the thread as we go along the build showing our process for all our builds.

So for whatever reason I cannot update the original post, but I digress. Made some progress on the FD and started mocking up the 9180 to our single wastegate manifold since I didnt want to lose the fun of open waste gate. Tonight I also started pulling the old engine.
After its out, its getting stripped to prep the bay for paint.
More to come shortly on the engine side. Hoping to have completed the half bridge tomorrow.

Some of you will not believe what came out of my car
Ancient E6S was probably before I was born. This relic looks like it was run as a piggy back. Could have been in a museum. Can't knock it that much since the car still made great power but Haltech has come a long way since than.
We chose to go with the Haltech 1500 because of the number of extra inputs. It is true you can keep adding inputs with the 750 via canbus, but after doing some quick math it was not cost effective as the additional canbus inputs were not cheap. A nice benefit for the Elite 750 is that you can run a 3 stage injector set up if you desire since it is programmed for 6 injectors. The Elite 1500 is only programmed for 4 injectors, but still supports 2 stage. For the secondaries, since I will be running 4 x 2000cc injectors, we will just split the signal for the extra injectors.
If you guys are interested in purchasing a haltech, turbo, or any performance parts or have any questions, message me or call me during business hours at IR Performance and I will be happy to answer your questions!

Banned. I got OWNED!!!
Out of all the porting options, what made you land on a Half-Bridgeport? What's the proposed powerband and boost levels for this build?
How are you designing the rest of the vehicle? Is this purely a straight-line performing highway/roll racing car? Track Duty? Weekend Canyon Carver? Do you have design parameters and a price point you're trying to meet?
Since you're splitting the signal on the additional injectors, are you worried about injector offset being completely different on your two-paired secondaries compared to your primaries since you're splitting the driving current to them? For your ECU you have a maximum current of 2A constant into 4 injectors, so you'd get 2A on each of the primaries and 1A on the 4 secondaries.
How epic will you make this?

All very good questions. Lets start with the half bridge. We are looking to make decent power since we decided to use the 9180 but we would also like to have it for where the car is still street-able to drive to shows and some track events. Now by no means am I saying a Bridgeport car isn't street-able but you do tend to lose out on the low end when bridging a car and start losing lower rpm response so a half-bridge is actually a decent in between. We recently just put together a half-bridge car for a customer on twins and the car seemed to have responded decently to the base map tune.
A common misconception is that a port will be a limting factor, but if I recall a few years ago Enzo tuning made a 9 second pass with a stock port. Plenty of people with stock ports making decent numbers so since the car isn't going to be a drag car, we didn't find it necessary for a full bridge.
We are mainly building the car right now as a demo car. Currently nobody has decent numbers for the EFR 9180. We want to see how our manifold compares to our competition using our in house mustang dyno. There are a few short runner manifolds out in the market currently for the efr, but many have been experiencing issues with boost control and crazy high EGTs which everyone knows rotaries particularly do not like the hear. Which is why I will also be installing egt sensors to monitor temps on the dyno and compare to our competition. The power levels will be decided on the tune and the use of e85. We will see how much we make on pump gas, than on a full corn tune. Probably 30lbs of boost if not more, but the motor will be built for it. Not to many people have posted a 9180 car with actual dyno numbers side by side. Plenty of videos of 9180s but even with the few numbers that are posted, they don't seem as high as they should be.
The car will have suspension mods as we go along. Currently sitting on Super Racing Teins which is something the previous owner had put in. For the mean time, all the bushings will be re-done. We also just installed a Kaaz 1.5 as I shredded my old stock differential last year at the track.
As for price point, its whatever it takes to make the car a reliable turn key car. So for that we will be wiring as many safeties as we can that the Haltech offers. It will be a testament to what we can build for any customer.
Not worried on injector amperage loss as we have seen similar successful set ups in the past with the similar set ups. This is another IRP built motor that is also running with the Elite 1500 and 4 injector secondary with no amperage loss. If there was to be any loss it will be little to insignificant. If there was to be any issues, the haltech would have caught it as even the car below had safeties wired in.

Wow! Looks great! Hope it is in running shape for DGRR, I'd love to see it in person.

I couldn't agree with you more! #BecauseRaceCar always seemed stupid to me, as did Stance. You invest all this time and money into something, only to limit it's abilities and availability to access it? NOPE, NEVER!

Got our hands on this trick intake manifold setup from Elite Rotary Shop. Initial impressions are very good. The casting is solid and machining very clean. The runners are significantly larger than stock. There is also plenty of material if someone wanted to port it even bigger, though I don't feel it is necessary. Over the weekend we started the mockup of our upcoming external wasetgate EFR 9180 single turbo kit that will be built around this manifold.

Hey Peeps,
Been really busy at the shop so the build is a little bit behind. So we hired two new guys to help finish your builds faster and on time without any sacrifice to quality.
Meet Tom and Cameron they are new to the IRP crew. Great to have 2 more car enthusiasts on board.
I started taking apart my old keg, and after a few minutes, I got infuriated and couldn't get passed the fact the motor did not have a thermostat... this was supposed to be built by a reputable shop in NY... Would explain why the car would take forever to warm up... the car did overheat once, but only because the fans didn't kick on, but the car did still have excellent compression.
Anyways I finally got around to finishing porting and polishing the irons. Getting them packed to send out to Chip Motorsports to get lapped and nitrated. I am also sending out my rotors and housings to him for a race balance and lightened, and to get resurfaced.
More Updates soon to come.

Update!
My apologies to those following the build thread! But I have been busy getting everything ready! The shop got busy and I cannot put this build before out customers.
I have begun prepping the body to get painted and I am going to have to decide which bumper I am going to use!
I already started doing on this bumper that I picked up from another rotary enthusiast haven't decided if it will go on my car yet
My engine bay was stripped entirely and now it on its way to get painted!
My motor is also in good hands
Can't wait to see my motor back in my hands after Chip works his magic!
SO NOW we play a waiting game to get all my parts back!
