Yes

Perfect. thanks!

Does anyone have any reviews/ feedback to offer yet?

Iam running twin 58mm at 13lbs on e85, so far it’s great, got the car on the road in August, great all around kit and so far about 1000miles on the comp oiless turbos, there holding up so far. I have the cmak also.

Hows the driver side piping looking? And do you have a under shroud?

Do you have a dyno chart?

Drivers side piping was fun to say the least but it takes a lot adjustment to get it right. I did mine on a hoist and it was still a pain.

Yes I retained my oem plastic skid plate but had to cut 2 small areas below the intercooler at each end of it due to its height.

No dyno nearby, about 8 hour drive to nearest one for me here in Canada and we are in the fall season with winter right around the corner. But seat of my pants feeling is real good.

Hey tiller, I'm in Ontario as well (Barrie area), where are you getting your E85? Closest place I could find with it at the pumps is Gen7 Fuel in Roseneath.

Awesome, your not far then, I am in Sault Ste. Marie, I get Vp x85 from the vp rep in Sudbury, 54gallons drums, not cheap but if you wanna play you gotta pay.

Oh true, no not too far! Ya, i heard it's not cheap but definitely well worth it.

Anyone else get their kits installed? I ran into an issue with passenger side piping fitting and just haven’t had time to work on it recently, looking for some inspiration to get back under there.

I think I may Be the only one with the twin kit installed and tuned on my z so far? Aside from Sasha

The piping WAS frustrating but the twin setup on this platform feels natural and all the swearing was worth it so far.

Iam at the point where I need twin fuel pumps, but we also kinda hit the point of max engine torque that the stock bottom end can handle. Time to source a donor block to build next.

I have it installed, waiting for a tune, upstate NY. Still alil paranoid about pipes rubbing. Can't wait to drive it. And Yes alot cussing and blood was drawn.

I’m going to give it another go tomorrow, my goal is to get at least one turbo fully installed

Damn this kit is such a tight fit, took me half the day to get this pipe in the right spot. We’ll see what else I get done over the weekend.

Does the F.I. Crash bar fit over this kits intercooler?

Nope

Currently tuning a 370Z with this kit. Honestly, great job. It's definitely a tight fit but the usage of a great flowing stock/upgraded header paired with twins makes for really low backpressure and the ability to run a lot of timing without any detonation.

Question, I’ve got the turbos on and close to finishing the install, but having some issues with the piping from the turbos to the IC, it looks like it would fit way easier if the heat shield around the headers was removed. Do I remove those?

Going back to this, turbos failed on both sides on the customer car within a few weeks of driving. Sent out to Comp and they warrantied them for free as they had a machining defect. Got the new turbos, and one side is making a funny noise.

I would love if this kit had normal ball bearing turbos... I think the hassle of having a scavenge pump system far outweighs the issues these turbos have.

Sob, sorry to hear this.

I have a parts needed to replace the comp turbo list on a Discord channel; if anyone needs it, drop me a line.

More or less than 900 miles on the Comp turbos?

Mine failed at 882 miles and 45 days.

Think he needs to give up on these oil less turbo's. Too many failures.

Ugg, that really sucks.

My scavenge pump stopped working in the first 500 miles so I disagree on the oil fed turbos. Guess what happens when you tie a turbo to the oil pan and that happens? Blown turbo, oil in intake and oil in exhaust, contaminated oil system, oil cooler, engine, etc. This was possibly install error as I popped a fuse in the pump line but it happened and it was a big job. If an oiless turbo has a problem then you have a minor problem. Ill take that over oil lines every day. Been there done that.
Everyone vocalizes their experience when they aren't happy but few chime in when they are satisfied. That's why Amazon pays people to actually reply with something positive.

Perhaps I'm biased since I have been on my 6.2L F150 Comp oiless for over 35k miles and it still rips around like day one and I abuse the turbo on many accounts. I tow a camper in the summer and an ice castle in the winters. I tend to plant the throttle for sub par reasons to put a smile on my face more than I should. I don't even oil it as often as i should because I'm looking for an excuse to upgrade but it just keeps living. Perhaps it's because it's a water cooled turbo vs pure air cooled but I'm going to an air cooled if it ever $hitz the bed on me.

Gonna have to disagree with you on that one buddy. There are always naysayers but the people who are invested in the forum and the 370Z do a pretty good job repping what is good as well as calling out what is not good. I totally understand how as a supplier you focus on the bad reviews as that has a negative business effect.

But those chiming in about the sweaty dumpster fire that is COMP turbo are those invested people I just mentioned. As an example, we pulled apart my busted (after 882 miles) COMP turbo at a Z meetup.

The gents who did so were physically present when humans first figured out that fire could make steam, and that it was good.

They determined that COMP forgot to grease the turbo before shipping it. That is an example of their shoddy manufacturing that should rightfully be called out.


As for the oil lines for the TC, first thing I and others (not gonna name names without their permission) did when replacing our busted COMPs was add filters to the oil lines to and from the turbo. Solves that metal fragment issue nicely.

That solves the cleaning of the oil cooler. Won't solve a blown turbo, oil in exhaust and oil in intercooler piping and intercooler. The fact you added a filter is good, but also eludes to the fact you're anticipating a failure or you wouldn't need to do it.

I am gona have To jump in on this conversation but I will try to stay neutral,TRY,
My z has had its share of modifications so far, gtm stage 2 kit back from the good old sam days, to currently twin 58mm oil less comp turbos, all the work has been done by my self, both kits. Tune down by seb from day one which is always a plus.

I gotta say I was extremely hesitant to go to the oil less comp turbos due to reviews I found all over , but I decided since I’ve gone this far in taking a perfectly good stock z apart, modding this modding that, upgrading things that were new, pushing the stage 2 gtm kit to it’s limits , now on to a turbo kit, why not , i new what I was getting into by going oil less, it’s all a waste of money no matter what kit you go with, but man those twin 58mm punch you in the back of the head and I’ve gotten to ,I believe 3000 miles on the them so far, and don’t jinxx me there still together, so I have warranty till July 2022 so I definitely could be back on here saying “hey guys I blew my oil less turbos up” but I’ll tell you those first 3000miles were fun as ...k .long story short iam neutral and all these options are risky, some more then others, I guess maybe if we don’t want any issues at all then LEAVE THE CAR STOCK. :stirthepot:

Failing to prepare is preparing to fail. Just my personal preference but I'd rather have a system that's drown-proofed six ways to Sunday and time-tested as opposed to some new nano-space grease that COMP made up to get around the plumbing, cost, and fitment issues inherent in oil-lubed and water-cooled TCs. and IIRC other members whose oilless COMP TCs catastrophically failed on them had a fair amount of shrapnel in their piping and ICs. But it all depends on a personal level of comfort I suppose..

I can get turbos!

You got me mine! Still trucking strong after 5k miles... approx. 4,100 more than COMPs.

WOW, Do some folks not know why OEM's started water cooling the center sections of the turbo's way back in the middle 1980's. It was for longevity. With only oil flowing through them for cooling they would fail like crazy. No coolant and oil flowing for cooling. It's not gonna last long at all. Stupid is a stupid does I guess.

Again, I have 35,000 trouble free miles on mine so I am a believer and would gladly purchase another. Some of those miles are from being in constant boost for hundreds of miles while pulling my Ice Castle. Those things weigh a lot and when trying to hold 75mph she runs in boost.

If these things were nothing but failures then COMP would not be in business.

Ok. We ALL get it. You love your S/C kit, and comp turbos…. But for the other 75% of the people that have them failing….. back to oil/coolant for them. :tiphat:

Well folks a little update on my twin 58mm BP Kit, lots of people complained about comp oil less turbos early on in my build, well guess what folks, the turbos so far work great(fingers crossed), so good that during some 3 wide racing at our local airport they bent one of my connecting rods....

So guess what showed up today? My spare block with machine work done by css, let the next stage of this build begin.

Nice what's long block specs your going with to take advantage of the 5858 turbos ?

For specs do you mean my internals?

Wiseco 9:1
Brian crower rods
Upgraded oil pump
Dynasty head gaskets
Possibly jwt exhaust Cams
Upgraded headers to, not sure which ones to go with yet.

What were your numbers before the rod bent? Curious to see how the power delivery mid twins compare to the single.
