Nice! You finally started, we'll sort something that will work. The 42R setups we ran here all did a easy 500whp+ at 10psi. They are great on 20B's and can be lightened considerably when making a aluminum backplate and TiAL housing. (I got a 45R down to 25lbs roughly) Either way shoot me a call or email, we'll knock something out.

Fuel rails came today. I went with the setup from XtremeRotaries out of Australia.

The kit is nice and packaged very well. The o-ring injector adapters are one of the reasons I went with this setup.

>>I'm curious, why not a peripheral port or something of that nature instead of turbo?
its kind of a loaded questions that has a lot of paths that come together for why (for me personally), but here are a few:
- within the constraints of thing like the race class, rules, equipment we can afford, equipment we currently have, et, the boosted setup is more feasible and gives us a lot of flexibility since we can tune low end with boost curve, it can make a lot more low end than the NA
- to make a pport NA make the same power, it takes a LOT of $$ and expertise as well, most likely more than the cost of the setup I am doing, there is some trade off with $$ for things like turbo kit vs pporting housings, et..but have you seen the cost on some of the top end intake/tb systems for an na 3 rotor? some NA intake/tb setups cost more than my entire setup all together!! LOL
- Also, most na 3 rotors do not make 450rwhp, and we need at least that. the only ones that come close are ones like the speedsource rolex engines and maybe some CLR engines, but trust me, they are a ton of $$ in comparison to what I am doing. however, you do have the reliability for an NA setup, so there is a trade off there too.
- if we run something like the 1lap again, or some other event where rules are different, we want the ability to run a bit more power at the top end, easily done with boost adjustment, with an NA you get what you get.
- I always wanted to build and drive a 20b turbo car, that is part of it too ;-)
with all that said, I would love to have 50K+ sitting around to buy a speadsource rolex spec NA pport 3 rotor engine package for the season ;-) cuz I also want to drive a 3 rotor NA car ;-) hahah
...but since I only have like 1/10 that budget, a turbo setup will have to do!!!
if $$ was no object, a proper NA motor with a proper geared transmission is win!!!
maybe a 4 rotor setup?, ... now we are talking!! :-)

I'm really glad that Damian chose to go with us at ChipsMotorsports, considering that there are so many qualified engine builders out there to chose from and every one of them has there own take on building race spec rotaries etc..
Thank you
I will keep you posted regarding your build progress...

Rotary Enthusiast
Got a 4 rotor you can buy 
Oh that's right nope it's in my car.
But tbh it's not that expensive. I spent 50k USD on mine and that included alot of work hours at the place it was built and mounted. Even tho i did abit my self. And a 3 rotor pp will do 450rwhp easy. I have seen 497rwhp as max on the dyno where mine was built
But looking good, 20b turbo is a great track setup, look at Re-A they had a great time with just about 370rwhp

hey jantore!! ;-)
>>Got a 4 rotor you can buy

hahah :-)
>>But tbh it's not that expensive.
Um, comparativly to what I am doing, yes it is!!! you made my point with your next line ->
>> I spent 50k USD on mine and that included alot of work hours at the place it was built and mounted.
Exaclty!!! 50K, versus what we roughly estimated will be a 20K to 25K build for me to do the setup I am doing. This includes cost of engine build, turbo kit, new ecu to run it, all that stuff. the only thing that may push the cost out a bit more is how we go with the dry-sump setup.
>>And a 3 rotor pp will do 450rwhp easy.
Well, I dunno, I would not say 'easy'. I would bet most do not make 450+ rwhp, only a few do, and those that do have a lot of $$ and expertise to get there, makign it not really 'easy' ;-)
but I could be way off since I only have a small window of known 3 rotor ppt to get data from.

I think in our conversation Damian must have miss understood what the Zinc plated gold fitting is for..
Its actually a direct oil breather for the center plate bearing and not a feed. The next process will be CNC center plate alignment for solid 1 piece dowel pins 2 pins total and a direct feed to the center bearing.
Hope that help before its get out hand regarding that fitting....
The before and after process consist of..
1. Glass blasting ( removes rust grime etc..)
2. surface grinding
3. Gas nitrating
4. A final light lapping to ensure a true flap side plate ..
More info and pricing regarding this service can be found here.

Ops, yeah my bad!!!
Correction on my post above, that fitting is the breather, not the feed!!!
