You bet, not my car and not my turbo/manifold but exact same as what mine will be:

 

Whose building the manifold? Someone local to you?

 

Will PM you.

 

Could you PM me as well? I would like to know who’s building that as well. I would be interested in purchasing.

 

Looking at a Renesis you’d never thing there’s that much room between the engine and the side rail.

 

I know I was also very surprised the first time seeing that photo. Especially after dinking around with the Greddy Turbo/Manifold to fit it near that location! I really can appreciate the shortness/lowness of this manifold, I'm hoping to have the same or better spool up as my Greddy turbo.

 

The only question I have about the photo is if the engine is shifted over a little. If its sitting there on a bucket or something and not mounted using a swap kit it could be shifted to the driver side a few inches.
Also it looks like the front of the turbo is very close to making contact with the front sub frame.
Probably would not work with those using modified Rx8 front cover due to the thermostat housing placement.

 

Good Lord that's a huuumoongous turbo!

 

The photo was not taken on-center. Hard to tell if it’s the angle or the engine is off center some. I did notice how close the compressor housing is to the side rail. I suppose it depends on how stiff the engine & diff mounts are.

 

I can't say for sure, not my photos and I've never seen that car in person. From what I understand that is with the Banzai crossmember. Even with the REW front cover my water pump inlet is going to be modified as it will interfere with the front sway bar. my understanding there won't/shouldn't be any issue with the front subframe.

Edit: I re-read what you typed Brad, yes not sure if this manifold will work with the Rx8 front cover, I believe it was designed with the FD front cover in mind.

 

Just an FYI i picked up one of those manifolds for my REW swap thanks for the info and will keep everyone posted with installation as well..

 

Looking for an S2 fuel pump assembly if anyone knows a good place to find one.

 

Cheapest Mazda OE parts supplier, if you were a registered racer then Mazda Motorsports would be the lowest price, approx. wholesale.

 

I would keep and eye on ebay. I purchased my S2 assembly with fuel pump for like $80 shipped. I use it strictly for lift duties now and have had no issues...

 

Thanks guys. Ended up going with an upgraded S1 version from Rock auto. I'm going to be modifying it for a Walbro 450lph and a return style system with a Radium jet pump. Will be replacing fuel lines with -6AN lines.

 

How do you intend to deal with the internal relief on the S1 pump? I question the wisdom of your plan. If you’re going to have a serious turbo engine you can’t be making poor choices on the fueling system. This is where a lot of fools and dummies go wrong.

For that size pump what you really need is to fabricate or buy a pump hanger and mount a pump with Holley Hydramat on that side with the pressure relief right on top of it and dumping right back through the top into the siphon which should also have a Holley Hydramat in the other saddle.

Alternatively use that S1 module as a lift pump and instead install a Radium FST-R surge tank which has it’s own pressure relief on top dumping back into the surge tank with the high flow pump in it. This way you don’t really have to monkey around with anything in the fuel tank.

I would strongly not recommend a traditional system with a pressure relief in the engine bay and a return plumbed all the way back to the fuel tank.

 

I tried to run a modified S1 fuel pump canister and Aeromotive 320 lph pump and would watch my fuel pressure crash above 15 psi in the mid to upper RPMs.

Make sure you have a functioning fuel pressure gauge on the car....

 

@TeamRX8

the fuelpump setup he plans to do is the same i did in mine. I completely gutted the housing to fit the 450, i removed the oem venturi and installed a radium jet pump, works very well so far

 

Ok, my apology if it’s my misunderstanding or poor assumptions on the intended configuration. Did you detail that with pics somewhere? I don’t remember it in your thread.

 

I dont take many pics when i work so there arent much but yes i posted some in my thread. I basicly gutted everything stock inside assembly to fit the pump, had to dremel the filter housing to make room for the pumps fat ***. The outlet of the pump goes out the housing with a bulkhead fitting that pretty much touch the pump when the assembly is compressed. I just put a small piece of hose like 1.5inch long to connect the outlet of the pump to the bulkhead.

then its all -6 an lines to external fuel filter, then to fuel rails, then to external fpr, then back with a -6 into the oem outlet of the fuel pump assembly, then onto the radium venturi i fitted inside the bowl.

made 3 1/2inch holes on the side of the housing to fill up the bowl fast enough.

 

Ok, here’s your post on it:

https://www.rx8club.com/rotary-swaps...5/#post4857526

however you used an S2 pump module. I suppose if you’re gutting it an S1 module may work. I’m not sure it would be any more cost to make a pump top w/hanger instead though. I’ve seen some supposedly offered in the $550-$650 range bare, which frankly is outrageous/ridiculous. Probably why they’ve never been in stock. I’m working on an alternative myself, but am waiting on confirmation on some details from the manufacturer before the feasibility can be confirmed. It would be a fully integrated drop-in assembly once modified with even that same 450lph pump if it pans out. Which the goal is to have a Holley Hydramat on the inlet too. On my NA car a 265lph pump is more than adequate with good bypass flow for the siphon.

 

I was using a s2 assembly with a 265 a couple years
ago but this setup uses a delphi assembly i bought on rockauto. I didnt want to gut a s2 assembly and be fucked if it didnt work so i bought this replacement unit and worked on it while the other one was in the car

 

Ah, ok. So I heard back from manufacturer on my idea for a pump module replacement and it’s good news. Need to double check a few dimensions, but am hoping to move forward on it. It won’t be a cheap solution either, but it’s a quality piece of equipment with the necessary features for performance use.

 

This swap is looking really nice

 

Sorry fellas, I don't know how I overlooked the fuel convo from 11/19 but yeah, I'm essentially copying Max's fuel pump set-up as it seems he is having no issue with it. I have FFE fuel rails with ID1050/2000's with external FPR.
