Yay, I'm so happy this is back! I'm sure all the small F&B, hospitality businesses are super happy too.

HyperGear vs Pulsar Turbo RB25DET
Dose Pipe Sutututu replied to Eric0's topic in Engines & Forced Induction
Issue with this are gaskets failures (x2) as mentioned above also it raises the turbo up further which may cause packaging issues etc. I suppose if you have an experienced fabricator around, you could cut off the T3 flange and weld a T4 divided flange. Another option (probably better) is to find an experienced turbo builder and they can machine a turbine housing to suit. I would even ask Tao at Hypergear to machine and send one over to you. Might end up cheaper for you. -

You might need an experienced turbo builder to machine a turbine housing to suit the Garret G30 turbine profile. I'm assuming you're in the US, maybe hit up ATP? -

Which brand turbine housing are you getting? Garrett seem to have dropped focus on anything twin scroll as of late. They only have it in T4 1.06. -

GTX series turbos, albeit reliable are quite dated now. I run a Garrett GTX3576R Gen 2 with a T3 1.01 divided housing and I get 0.8bar of boost by 4000rpm and about 4600rpm is when it's all in (1.8bar) on a 2.5L, VCT NEO, 264/272 cams + usual mods. Makes a sensible 437kW on E85. I do rev the motor to 8600rpm but at about 7500rpm or so it's not making anymore power. If I had the opportunity to do it again, I would get a Turbosmart 6262 or a Garrett G35-900. Probably same response but will go 500kW+ -
Nismo 1.5 way Stub axle issue
Dose Pipe Sutututu replied to OO Dan OO's topic in Suspension, braking, tyres and drivetrain
either that, or the said LSD is worn OR the initial torque setting (being a Nismo one, I'm assuming it has the adjustment on the RHS when you pull out the stub axle) it is set so low it's not engaging -
Nismo 1.5 way Stub axle issue
Dose Pipe Sutututu replied to OO Dan OO's topic in Suspension, braking, tyres and drivetrain
sounds like you've just described a helical/torsen diff, when you load up the rear wheels with the handbrake, then I'm assuming both wheels will then spin -

Yep, like how people insist VCT does nothing, delete them OR say how twin scroll is a waste of time. -
RB25DET NEO Turbo water return line
Dose Pipe Sutututu replied to shortyboy's topic in Engines & Forced Induction
I've driven it around "in da hooodd" and it seems ok, have driven it around with the A/C on as well to generate more heat. So far no leaks. Yet to do a long drive OR a track day in it, so both will be the tests. I think if I were to do it again, I would just plumb the water return straight into the intake manifold's bleed ports (un-used) on the top side, noting that I have an aftermarket one. I hope this works well, because I cannot be fked working on the car ever again In terms of your usual highflow kit, I would just return the water to the hardline behind the head. -
Time to get measuring (not a fun job)
-
Another thought, are those actually NEO cams made for the NEO head (shim over bucket) and not the non NEO head (hydraulic lifters)?
-
@Toff if it's a NEO and it's making the noises you're describing, it sounds like you need to work on the valve clearances and measure/replace shims as required.
-
I am going to chime in here and say that is very bad advice for a built motor, making decent power of 400kW+ Especially if the rings have been gapped on the looser side. The more power you make the heavier you need your oil to be to be able to maintain that suspension between the moving parts, if not you'll have journals and bearings making love and grenade a motor. Remember that all moving parts inside the motor aren't ball bearing and are journal bearings and require oil to separate the surfaces from contacting.

Best chassis for motorsport use
Dose Pipe Sutututu replied to Blakeo's topic in Motorsport Discussion & Builds
Depends on how extreme, however if you look at SMSP, they're all dominated by Hondas and M cars on amateur/street car events. -
Very even markings on the spark plugs, looks quite healthy to me. I may have missed it, however is your sump and catch connected? If so, perhaps block off the sump to catch can vent/drain and see if you get less oil consumption. (Assuming the oil vapours have a bit more time to catch along the oil galleries/passage inside the motor and not continue as vapour out of the cam covers). Worth a shot, I have a ball valve on mine so when I'm not beating it at the track the sump/catch can drain/vent is blocked off.
-
Had to google what a quart is lol.. so rough as guts a litre. That's a bit excessive, also what oil weight are you running? The whole steam cleaning idea isn't too far fetched either. Maybe as you suggested, turn off the WMI (assuming your Kebabtech pulls timing, boost, etc.) and run it for a bit and see if there are any noticeable changes in spark plug colouring.

ZF 8HP or go home -

Dose Pipe Sutututu replied to rbs30's topic in R Series (R30, R31, R32, R33, R34)
350/370Z CD005/9 seem to be a good choice, but you'll need to address the diff ratio issue. -
Ross Power Steering Idler Kit
Dose Pipe Sutututu replied to Dose Pipe Sutututu's topic in Engines & Forced Induction
I think throwing the hydraulic power steering system into the trash and converting to electric power steering, e.g. Astra PS pump would solve many issues. -

Useless lot aren't they? Releasing stuff on the market that doesn't do what it's supposed to do without you stuffing about with it and spacing out the spacer lol. FFS. -
Idle issue rb20det
Dose Pipe Sutututu replied to Ak brar's topic in R Series (R30, R31, R32, R33, R34)
What ecu? What injectors? Using AFM of MAF?
