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

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
