I agree V mount is the way to go, fresh air to the inter cooler and radiator.

That's an intresting set up TEAMRX8, seams like a lot of mucking around though with the radiator, getting new hoses that fit and such.

I would have thourght the intercooler would have sucked in some hot engine bay air being in that location.

Getting hoses is the easy part and intercoolers don't suck.

Better get in line then. I am crazy busy...

I don't have an install shot, its been on a car running for a long time..

relocating the radiator allows you to reconfigure how air flows through and around the vehicle

Turblown making a low mount system. Seems like a done deal. Great for California and I always felt that it's pointless to buy greddys kit when more than half of it gets replaced.

On a sidenote, all of you with boosted rx8s, was it really worth the money you dumped in it for FI?

I am happy so far. What gets replaced in the Greddy kit? My turbo was upgraded but nothing was replaced. With any turbo kit there is always tweaks and room for improvement.

Depends what you pay for it - 2nd hand can be an excellent deal.

Depends on the result you get - which in turn depends on the decisions you make and how you go about the whole thing .
Done poorly it is the worst nightmare you can possibly imagine .
Done properly and it transforms the car into something very special .

+1.

The way I usually do things is do it right the first time so no headaches down the road. Yeah ungraded turbo, I also don't like how the manifold cracks easily. It'll be great to see a much better manifold made from turblown. Better couplers and lines. Garrett IC core and having to buy aem intake with greddy sucks, everything adds up =( lol. That would be my ideal kit. But with a fresh rebuilt motor I want to see 100k miles with a mix of street and track driving. But haven't seen it done so I'm just waiting to see if development ever achieves that

I'm in line.

Fast, Cheap, or Reliable, pick one.

Let me know when you find this fantasy kit

Uhmmm im pretty sure Elliot mentioned that hes building a manifold for a low mount kit. He also has a turbo that would fit it well. Just need braided steel lines/hard lines, better couplers and buy all the piping yourself. Garrett core that Elliot uses and make a intake that makes it a CAI like how all Greddy users been doing. Thats the definition of the "fantasy kit", So its been found?

He was referring to your "100k miles" statement

Ahhhhh. My bad. What's the most what anyone's gotten anyways?

a couple of dyno runs :hahano:

no srsly, looks like some advances have been made but is still early to draw hard conclusions regarding your inquiry

IMO the side seals will still be the weak link eventually, but time will tell otherwise

30k? 50k? Not sure the longest someone has gone with a FI Renesis.

Way too many variables to consider since this is not an OE setup. Every install is custom setup.

So will the low mount system be the better choice? I don't have an issue pre mixing as long as it provides as much longevity for the engine.

Also, can you use a top mount intercooler with your top mount turbo system?

Thanks,
Joe

bit hard to fit a top mount intercooler with the turbo being there....

If you want a Vmount, or top mount intercooler setup you need a low mount turbo system. I don't see any difference in reliability engine wise for top mount vs low mount. A top mount turbo system will definitely have a nicer flowing turbo manifold, and chances are might make more power up top...

I think to have read that you could get some inconel springs for RX7 sideseal, is there any reason why RX8 shouldn't get the same opportunity? After what I've read(and are experiencing by my hot- start problems) spring weakening is the problem, not that the seal cracks?

You have a link to this spring manufacturer?

It's nearly impossible to get any metal spring regardless of material type to maintain a temper resilience above a certain temperature

team hit the nail on the head. When Mazda started the side exhaust port--the side seals became a target in the crosshairs. The on top of that they moved the side seals closer to the combustion face. That equals more heat.
Then FI is going to cause even more heat as more power always = more heat.
30k-50K would sound reasonable, BUT it all depends on many factors. The tune, the gas you run, the upkeep you do, the temperature controls you have, how often do you go in boost (tracking/street), etc etc.
If you could get 50K out of an engine street driving and doing 2-3 track w/e's a year--them imho that would be great.
Realistically, if you track this bugger and place high loads on it in the higher gears for any lenght of time, then it is a toss of the coin. 1st, 2nd, and even 3nd gears rev up so fast that they are usually not a weak area on a properly tuned/maintained 300hp engine. 4th and 5th gears however --again imho--is where the problems that I know off usually show themselves.
I have no idea how to fix that.
The bridgeport may help cool the side seals some? IDK for sure but it appears it could.

I was referring to the premix vs omp. But what I have read before, premixing is better because the oil injectors cant cover the entire surface. But that discussion is for another thread.

On your site you have $6500 listed as the price for the kit. What is the cost of the "Tier 1" kit you mentioned? I am looking for a introductory level kit.

Thanks,
Joe

Wow that would be fantastic!!..... I bought my GReddy kit with 100% intent of waiting for a larger turbo option (3071, 3076 or GT35). I'm assuming this would easily fit the GReddy hard piping?




+1 I am also not interested in converting to a top mount now but still want to hit that 350+ whp mark and I'll be convocating from University this spring too...$$$$ :)




I replaced nothing.... stock GReddy with the simple mods done and MM tunes... Was it worth it... I absolutely love this car and double that with the turbo... only complaint I have is how undersized the stock GReddy turbo is... Other than that I have experienced zero problems @ about 7k miles on the turbo. Plus the amount of support available from other members with the GReddy is a huge bonus and was a great asset during install.




Most guys already run upgraded couplers with the Older GReddy kits... correct me if I'm wrong but I believe the newer GReddy kits (which relocated the Jet Air hose connection to the hard pipe just upstream of the TB) comes with better couplers?

Also I don't know why you think the stock greddy IC needs to be replaced with a Garrett core... definitely not with a stock greddy sized turbo (including BNR upgraded)?

The AEM intake I agree is a great mod; as are most of what you listed above but at the same time they are not necessities.

May I ask how your getting air to the IC? ducting? Pics? Just curious. :ylsuper:

a large vent in the hood

nor are they super expensive to do, relatively speaking, you are turboing a car after all :wiggle:



I really like that lower mount manifold. Very interested as well

I guess I was trying to understand the flow of air...I know MM says it works but I cant help but think...Isn't the hot air coming off the radiator flowing through the intercooler? So the vent in the hood only allows the air to escape the engine bay not enter it.

Does this help? It's actually impressive to see this setup in person.

hadn't seen it in person, but it looked like there may have been a tray under it with a forced cold air feed, he would have to confirm

I believe Knightsport did something similar in addition to also providing a more traditional v-mount setup in some purpose built swaps they did

they also have a new kit that appears to maybe relocate the radiator in the v-mount position for non-fi cars as well, it implies this in the name and extremely basic general description, but I have never seen any details or other info that fully explains the kit

.

6500 is the price of the tier 1 kit(needs an ecu and will make 330rwhp, with potential for 400rwhp with add ons). I figure the low mount will be about the same. You can however purchase just the dp, and manifold combo and make the rest yourself if you like.

Someone else asked if the low mount would work for a greddy upgrade(use greddy intake, fmic etc) and the answer is yes will small modifications.

this is their traditional FD3 setup, it offers some distinct advantages imo

Thanks 9k but no... :cwm27:

I've seen a similar pic but it still does not clarify where the positive airflow is. I'm inclind to think that air is leaving out of the engine bay through the hood which means the IC is getting hot engine bay air. Not saying this is not working cause it appears to be just trying to understand.

Now if he has the radiator at an angle like the pic Team supplied then this would make more sense I would think...

You would have to look at his whole system to get it.

What additional add on's do you recommend for let's say 350 wHP?

someone need to translate this http://www.knightsports.co.jp/blog/R...P/post_76.html

I like this setup I wouldn't mind having it on mine later on. But I this setup would work because of the air flow being force throughout the intercooler giving it fresher and cooler air than the front mount.

more or less what I already told you

O yeah Turblown my ride should Be starting up this weekend depending how quickly the my oil thermostate gets in that I orderd last Thursday.

The air passing through the radiator brackets and piping kit for discharge in the direction of ground.
The cooling effect of the more genuine layout.

^ thanks for the translation and nice translate pic Team, i'll use that :)

Ignition coil upgrade and a midpipe/catback

i see the tray under MM's intercooler and I think i know how he is feeding it cool air.
I may be doing the same thing. The front support bar can be reduced to 1/2 its oridginal size and then the front grill can be opened up. This provides a clear path of air from the front grill. the details that he did --i am not sure off. I dont think there would be much pressure at the IC front?, But it must be enough.
I bet he has his engine radiator air diverted in another way than oem? But maybe not?
If not I do wonder about the air pressure in the engine bay or maybe the IC is actually pretty much sealed from the engine bay once the hood is down?
It is a nice set up.
Where is his turbo air intake?

Does the Tier 1 $6500 kit come with the GT35R? Or does which turbo I choose not affect price?

Thanks,
Joe

It comes with a Garrett Journal bearing GT35R. Prices don't change from To4E(57mm) to To4R(66mm turbo). To4E is the smallest I would recommend to use on the top mount, and a To4R is going to require a return style fuel system to use its power potential(500+rwhp). Obviously we can go bigger, and have done it, but it will add substantial cost.

Its best to tell me how much power you are looking for, driving style, etc and I will set you up with the best possible combo. It might be easier/faster to just start emailing me direct; turblown@gmail.com



On a side note, I looked again there is NO way to fit a nice top mount turbo manifold with the OMP. If you want to run the OMP you must by a low mount turbo system.

How long until you guys release a low mount, will you be able to use a BB GT35?

People want to keep their OMP, you need to offer low mount and top mount to your customers.

try reading this thread

How much would it be to upgrade to a ball bearing GT35R?

Thanks,
Joe
