*points to Matts graph*

Looks like it's ramping up fast to 20 then tapering down to 17

Interesting...what turbo? Ex gate? Return cooler or straight piping?

I'm on 15-16psi

Guessing from your slightly better response my turbo is actually slightly bigger (unless you've done more than bolt ons), however my turbo gets a bit choked up top from my cooling and exhaust setup.

You laugh now, but when I'm at a formal occasion with a shitty DJ and they need someone to drop Dre beats...I have something up my sleeve.

Almost the same setup as yours. Yours seems to hold torque for longer though, only just.

Yeah that's weird...shouldn't that produce more power at the same RPM / speed though?

Though that assumes runs done in the same gear and diffs. I don't know how dyno dynamics calculates engine torque...obviously some sort of correction for it; maybe it's open to

variability.

R34 OP6 Hypergear Highflow, Internal gate, cheap Returnflow cooler, standard cooler piping in bay, scotty's intake pipe (which doesn't quite fit and I need to ask him to modify it since it doesn't line up with the turbo and the airbox at the same time...)

Pretty sure the restriction is the rear housing not being able to flow enough

Ah yeah. Mine is an HG SS1PU, which from memory has a slightly larger rear than the OP6 highflow...but I made him match it up to a bored out standard Nissan comp housing up front for dat dere stealth (that could also be choking me out up top). Using his preferred comp cover Stao made 290+ with an SS1PU on his car...albeit Trent's dyno.

Intake and cooler piping is standard with a return flow, so they do sound very similar setup-wise. Could also be that your turbo is simply a newer / more efficient model or a difference in engine health.

Pretty damn good turbos I must say, I've had mine on for at least 50,000 now and running flawlessly.

Brought it home yesterday, pulls like a freight train... midrange definitely changes a car way more than top end power does. before it was breaking traction (265 ad08r) at the top of 2nd and chirping 3rd, now it's breaking traction for most of 2nd and if I change into 3rd hard it'll keep it going. Need to get used to that...

Had some slight coldstart issues when I started it up tonight, started and idled fine, but touching the throttle during the first 30 seconds made it choke and revs dropped down to 400 before it recovered itself... fine when it's warmed up (approx 2 minutes)

Sooooo, best of luck to my neighbours with it idling for a while at 4:40am on Saturday morning

you should be a easy 4 sec ahead of me....

Thus, why I've got work to do... Need to build confidence and learn how to turn in correctly...

ALSO, WELL DONE EVERYONE!!!!!! Page 3876 was purely about cars, not a single mention of politics, housing markets, vase selection criteria or which limited edition sneaker is just retro enough to be cool without being pretentious...

Pretty normal for E85 to be unresponsive and choke up with a cold engine. Spark plug heat range prolly a factor too.

Once started I can use the throttle immediately, but I always roll it on slow...if I stab too quickly idle drops. It also need a bit more revs when cold and letting the clutch out for take off or it will die in the ass. After a couple mins of driving or idling it runs fine and dandy with dat super response, but I've learnt how to drive it so that I can start it and start driving basically straight away.

As for actually starting, that depends how pure the E85 is in the tank. While there's still some petrol in there, starts will be easy. With pure E85 and on cold mornings mine can take 2-3 cranks to turn over. Helps to add a minuscule amount of throttle as I turn the key. Warmer weather and it's first crank good to go.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
