Ah gotcha. Theoretically as long as the pressure from the turbo line is greater than the hydrostatic pressure from what's in the pan, the droop is negligible and it should be fine. But oil is super viscous and the return line is way bigger than the feed so I'm not sure if that's still the case. (Lots of pressure losses)

Those "nubs" were added to keep the couplers and clamps from slipping off

Trust me, it won't drain that way and you will have problems.

Womp. Well there goes that haha. I can probably tig back on some of those after I get the swing of sheet aluminum again. I know on some of the pipes that was the only place the couple would sit and it made mad boost/vacuum leaks.

I figured that was the case. I was just basing it off theory but everyone knows how well that works in real life.

Looks good! Could you post up a log so we can see how the kit is doing?

I'm not surprised corners were cut but the proper tool for the job is not very expensive.

This is a cheap way to do it.

You just need to ensure the hose clamp is past the "nubs" and not on top of them.

Seems like a HELL of a lot of modifications/fabrication required for a kit that is supposed to be bolt on.... Did Gregs kit follow the same routing/have the same fitment issues or is this because yours is a production kit? Doesn't he have aggressive wheels on his with no mention of not being able to turn the wheels completely?

Anyways man, you've got hella more skills in the shop than I do, cudos to you. My GReddy kit fit in as advertised so there wasn't really any surprises for me; hope it gives you many years of turbo greatness; I know I couldn't go back to no boost!

Yeah, I wasn't really sure what I was getting into in terms of nitty gritty details as this was my first time turbo charging anything. And I don't think Gregs had any issues as he had one of the prototype versions and things were still being worked out in terms of production en mass. And apparently I'm the only one with the wheel issue as I've been talking with another kit owner and he's totally in the green.

Thanks man, its been a wild ride. I just hope I was able to give some perspective on my install with this kit. It was a pain and a half, but I love it!

Yeah it was my first turbo install too and I can tell you now, if I ran into the things you did I would have given up haha.

Good work here, glad to see you stuck with it. That steering issue would drive me crazy, have you addressed it with the manufacturer?

There is no way that a kit wouldn't require modifications to fit. The undertray and sides and battery box areas will always need to be modified. If you are adding aftermarket radiators and other peripherals you will run into unique problems as well.

You will never get a "bolt on" kit that won't require any modifications

I'm not talking about cutting the under tray and other plastic parts.... I was more reffering to the welding/cutting of the crash bar and the lathe work that he required. I agree no kit is completely bolt on, but I didn't have to have any experience as a machinist to install mine.

The difference being I was able to modify everything for my install with nothing more than a dremel. It seems as though the kit that this particular guy has had more than a few fitment issues, even compared to other RX8Performance kits. Not bashing or slamming his build in any way, just pointing out what I'm seeing in OP's posts. The Rx8Performance kit is one I'd one day love to try (especially after seeing Gregs) but I wouldn't have expected it to be any more difficult than the greddy kit to install, seems like this particular kit was "off" and if it was me in the OP's shoes I would have felt a bit overwhelmed if I thought I needed to go to the extent he did. Considering he can't turn his wheels completely I'd say there is something dimensionally wrong with this particular kit

I think Gregs didn't buy a complete kit as he used a few of the parts he already had so fitment was easier.
I have heard from another source in the UK where the guy had just as many issues as the OP in installing his ... if not more .
Suffice it to say that .... you are gunna need some skills to install this kit . I think the final outcome will be worth it though and I don't see anything better available on the market.

I would like to move mine inside as well. . But that'll be on the next motor.

Shouldn't take too long.

My turbo manifold didn't have any issues with fitment, I basically purchased a kit minus the inter cooler and piping so I could achieve a certain look in the engine bay. I really like the simplicity of the charge pipe running outside, mine takes some patience routing in the engine bay, having a low mount kit is no walk in the park especially when there is a larger frame turbo in such a small/tight area but this kit is well worth the effort.

Well if I was to go this route I would try and use as much as possible from my existing GReddy kit. I'm mainly interested in the manifold and larger turbo that can hold boost all the way to 9k. Still need to do more homework comparing this to an upgraded turbine/compressor (60-1 with 11 blade turbine) to my GReddy. Probably will come down to one option being much easier on the wallet than the other anyways

And with the Canadian dollar as god damned low as it is right now I won't even be considering this for a while yet.

Thanks for the info you guys with versions of this kit, time to do some more build thread reading I guess. Sorry about the thread jack OP!
