Decided to do an update I usually just look at other peoples post i thought about selling but then I wana sellong the motor since its fully built but then I'm like I just wana see this bitch run. Just as I people comparing turbo kits at what not even if I had a different turbo setup motor still was built by turblown so they still would get credit no matter what no turbo 8 is alike and will never be. My goal is still 500hp

Gas as yall already know is what is causing this carbon buildup and it lokks about normal to me for a 40K engine? You want cleaner and you are FI then install a water meth system.
Dude--not to say anyone is wrong or anything, but I would advise very strongly to NOT delete the omp on this engine.
Oil injection is not the reason for carbon buildup ( you know that) and if you will read Eric Meyer's post on his anaylisis of using the omp or deleting the omp you will see why you shouldnt.
The side seals are not properly lubricated without the omp---the side ports on this engine makes it not like the older models in which you can pre mix only and do ok.
Dont forget to test the oil nozzles before remounting--they are starting to show their age on a lot of engines too.
There is something to be said about local builds versus way off builds. Sure agree with you there. Mazmart has said they are not that familar with an renesis FI build. But, they are learning and it shouldnt take Rick long to learn!!

Good point i have read pages and pages about the omp and the good and the bads. I did check out that post that Rick a while back from what I see its been debated for a while. What I don't like about it is that even of its hooked up and it goes out there isn't a limp mode from messing up the engine that I know of. I just like to make things less complex. I really like to see some data on someone running with out one for about 20,000 miles.
I see what u mean as protecting the investment.

while i totally respect your decisions on your engine/ car, i tend to agree with the points olddragger made in his last post.
while i totally believe in premixing and a functional MOP used in tandem with my pre-Renesis rotaries, i stopped premixing with my Rx-8 because i still haven't convinced myself that it's not responsible for the troubles i had with my fuel filter/pump. i plan on trying again (this time with the stuff i get from Amsoil) when i get my 8 out of storage.
that said, i'm sure you'll enjoy your car when it's done. in my limited experiences with him, Elliot is good people and he knows what he's doing.

Original Turbo 'd Auto !!
I'll throw my .02 cents in.
As some know I'm a pre-mix only as the MOP had to be remove for the DP. Could the DP been made diffrent to allow space for the MOP? Sure, we're only dealing with Time, material and space constraints.
But as the referance kit for Turblown top mount setup, for now oh well. I digress.
I like many others have read the threads To Pre-mix, Pre-mix and Run the MOP, or just the MOP and not Pre-mix.
Since i can only chime in on the Pre-mix only setup and now have 7k on the Top mount, i have not seen a diffrence at idle vac. It stays around -20in Hg (no load/ park or N).
What i have noticed is depending on the amount of premix added the vaccum will change when the keg is cold and when it's warmed up.
The 8 runs best (imho) with 13 gal of gas and 8 oz of pre-mix. so this is a 200:1 ratio pre-mix X gas.
I get a stable vac reading at -15 In Hg at a stop light. Warm or cold motor.
If i do a 100:1 ratio which is 13 Gals of Gas to 16.6 oz of pre-mix, the car will "hunt" between 15 -In Hg and -10 In Hg. At a stop light on a Warm or Cold motor
I feel a 200:1 is too "lean", but without tearing the motor down, Who really knows ? My last comp check was at 90psi both rotors and all 3 faces were really close to each other.
We will really not know the long term pros or cons of just a pre-mix only configuration until there are more of us. Then how do we weigh in the factors of Drive style, enviromental temps, the upkeep, ect?
Mine a reman from the Allied Tech rebuilders that did the first remans. I will drive it till it breaks and go from there.
Saucy, I'd really like to see your project be completed. Its been down just a little longer than mine was. Tis so damn close now, stay the course. Many of us would like to see that 500 whp you're going for.

Agreed that pre mix versus omp versus both has a lot of speculation and many different opinions from very creditable people.
However, the only documented data collection concerning the affect that this has on the corner/side seals that I know off comes from Eric Meyer, who imho is the undisputed data collecting king. He has battled getting more hours out of this engine than anyone i know. He has been fighting that 10-20 hp reduction in power after only a few days on the track for a while now. During that time he discovered the value the omp provides.
Now a forced inducted engine that is driven on the street versus a NA high rpm track only engine is a different beast, I do grant that. Still, accelerated corner/ side seal degradation in engines that he has ran without the omp was seen and it is repeatable.
Drop him a PM. He will share his findings--he is that kind of guy.
If at all possible i will run the omp.
Have any of yall studied the S2 model omp? God, i wish that could be placed on the S1 models. That omp actually puts pressure to the oil nozzles, among other stuff. It is sooooo much better.
Looking forward in following this build.

Thanks OD.. now its fuel system setup. Right now I'm looking to do a system that is almost kinda like a bulletproof setup. I already have the fuel rails. Next would be the automotive fuel pump. The thing is about the fuel starvation issues , I have a guy that would like to do an external anti surge take to make sure it will keep flow at all times. Would this be necessary or is it overkill. Pretty much all said and done it fuel setup is good for over 800+HP not that I'm trying to go that high its all just piece of mind I guess..

Update: bump
Since I'm still waiting on items, Im just looking for thing to do on the car. I drop the transmission the throwout being needs to be replaced with a couple bolts just waiting for those to come in and also took off the sound material for 09factor lol , it does make the engine bay look nicer.
I have so much time on my hands I'm going to create my own turbo manifold. ill see how that goes.
hopefully I can get everything I needed in so i can start the motor sometime at the end of June. ill be running stock injectors with the kg fuel rails until I break the motor in.
other than just waiting on thing I'm putting some lowering springs on the car to keep me busy till then.

I think I over spent on my cooler setup This mod is not for the weak hearted but u can go basic if u want..
The set up is
2x Setrab dual 25 Row oil coolers
Mounting brackets
-12an lines and fittings
Hamburger oil filter adapter
Areomotive -12 y-fitting
Mazmart oil pressure mod
I just over spent on this build entirely and still wana let me know if this oil setup is over kill

Looking good dude. Great cooler choice like Dan says. What kind of thermostat?
I would recommend a fan controller ( I dont think the pcm can be made to turn both fans on at the same time--always?). Adding one to my car made all the difference in the world.
I have always liked the Black--rx8's with black enkei rpf 1's--they just look---evil
