@V28VX37 There are no oil galleries inside comp cover. if engine rocket cover breathers are plumbed into the induction pipe. remove them and that bit of residue should clear.

For the  1hz cruiser we can high flow your stock turbocharger using G1 profile, its quite response with plenty of torque. It does need water and oil lines, everything else bolt back on with no fabrications.

Thanks Tao, I was wondering about that, makes sense. Yes it's got the standard breather setup plumbed into (Scotty's) induction pipe.
Looks like the engine might be breathing a bit more oil then after the recent head gasket change. Should I be looking at a catch can?

Also if the turbo oil seal was damaged, I'm guessing it would be leaking at the core right (not at the comp cover)? 

The seals are SS C clips, they don't wear unless of a thrust play, means turbo would've failed. The front collars are engineered to throw oil away from the centre shaft and the rear don't, so in case of turbo failures, the rear seal is likely to leak first.

I've just installed a simple catch can setup and I'm still getting a drop of oil collecting at the bottom rear edge of the comp cover, it's really strange. 
I've previously tightened all oil and coolant lines and the turbo core section seems dry as far as I can tell from above and below. I'm still getting good boost, so the turbo is definitely working.

Any other suggestions on what else could be causing a minor leak at the comp cover?

 

Hi guys,

Keen to share my results, hopefully they might help others in choosing their setup.

S1 RB25det, 2013 ATR43SS1PU turbo, stock manifolds, 3" exhaust 100cell cat, megasquirt ECU, splitfires, sard 850cc injectors, DW300 pump, undersized intercooler (high intake temps and around 4psi drop).

Graph shows 98 on gate pressure vs ethanol with a little more boost.

Looking for some feedback on my dyno graph. Is this normal because power and full boost seems to come on really late. Car is r33 gtst s2 manual

Mods:
-Hypergear op6 highflow ball bearing G3 profile.
-power fc
-xspurt 1000cc top feed injectors
-walbro 255lph fuel pump
-blitz return flow intercooler
-full 3 inch exhaust
- apexi pod and solid intake pipe mod
-splitfire coilpacks
- NGK sparkplugs 0.8mm

^ take it to a different tuner, also are you running a cat - if so which cat? plus need more boost

Cant really afford to get another tune. I had a chat to the tuner and he said theres nothing that can be really done and its just a laggy turbo. Im happy with 250rwkw i would just have liked full boost to come on earlier. Im pretty sure its a highflow cat not sure what brand though.

Also the wastegate actuator was set at 18psi. But it was opening up at around 13psi and they had to use a bleed valve to bring the boost up.

I've seen a tune file from said tuner from a car with similar mods. It was horrendous at the very least.

Also your cat is probably restrictive.

FWIW I've been happy with Chasers and Paul's always done a good job with my tune.

Check that cat, my car picked up about 25 rwkw going from X force 'high flow' to a proper Venom 100cell.

Edit: Mine's a 34 with Nistune not PowerFC

What boost controller are you running?

Something is not right, I'm hitting 20psi with the OP6 highflow at 4900, and thats on my RB20 which is 500cc smaller and has no VCT.

With the OP6 High flow, Just check to make sure the actuator is preloaded and shut, leaks and active VCT. Alternatively you can send it back and swap the turbine housing to smaller 21U. The op6 should be making 20psi at 4100RPM on a R33 Rb25det engine and maxing towards 290rwkws.

A decent CAT really make that much difference :O??????? How would that compare to decat?

Where's the best place to pick up one of these venom 100cell cats?

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
