I think up 200rwkws @ 15psi is all good

The 8 additional psi for 8kws part is not normal. Is the car running a 3inch metal induction pipe? if so try again with exhaust dropped from the cat.

Also is VCT enabled with this SR?

How do I embed photos?

Got my s14 tuned today with a hypergear ss1pu, bit of a disappointing result, but that's more to do with my setup unfortunately.

Photo speaks for itself, high boost, low power, choking for some reason, new exhaust coming.

IIRC results were: 188kw @ 14psi, 200kw @ 15psi, 203kw @ 18psi, 208kw @ 23psi

Something here is very wrong. What did your tuner say about the issue?

It's reasonably proven now that the SS1PU on an SR is within the realms of a responsive turbo, and will make 240 without breaking a sweat.

Yours is both laggy and failing to get anywhere near the power. If you go back to page 1 you will be able to find my dyno sheet in the reference list, mine is an SS1PU on an SR with NO VCT.

you sure your tuner knows what he is doing?

that power band looks totally McFuarked.. looks like there's massive amounts of timing pulled out after it goes on song.. also looks really laggy?

My exhaust is really mix and match, 2.75" china split dump, mild steel front pipe, stainless 3" from there to 2.5" muffler, back to 3" stainless with twin 3" tips. He said changing this to a straight 3" will really help. If the gains are shit after that, then to look at the cam timing.

It felt really responsive when I first put the turbo on last week, and that was with the ecu still tuned to big injectors and the 3071, definitely feels laggier since being tuned though.

It was determined that the VCT in this is not working, so I'm on the lookout for reasonably priced vct gears as well.

Comparing the graphs, this comes on a lot sooner than the 3071 60kph instead of 102, but full boost on this is at like 150, whereas the 3071 was 140.

The tuner is fairly reputable up here in Brisbane, but maybe I will try somewhere else after I change the exhaust.

While I'm here, is 3.5" exhaust setup going to be too big? Found a well priced stainless one secondhand, but not sure about the size...

Also need check cat inside.

Look carefully at the cat with a broomstick and/or a hole saw

This. Use the broomstick to remove the inside of the cat so you can see inside it and check it's clear.

I believe That SS1PU's result is a little low, might due to some parts of the setup. Refering to John's 21U's high flow result. It made 320rwkws on E85 with factory setup, same as what SS1PU made on a proper high mount with external gate. The new high flow should make similar power or higher power as the SS1PU. Which I will just have to work on a more responsive and more powerful version of it :D

Another result of a bolton version of SS2 sent in today. from a R34 Skyline using Pump 100 fuel.

Final figure of 293rwkws @ 17.5psi

And perfect internal gated boost control.

That's a very good result, I assume it's a manual? Is it possible to get a list of supporting mods?

I know that the auto driveline wastes power but there's a 36 rwkw difference between this and my R34 auto (same boost), which seems like quite a bit.

I havent had it on my car to max it out yet, but current result does appear to be the case. specially those results are from 20 years old stock engines.

Do the water lines and oil lines stay in the same spot when you high flow one of them?

Or will it take some adjusting of the water lines to make a high flow 21U fit like how you do with the SS1PU

They all boltup using stock lines and factory drain, so fitting up is bit easier then the SS1PU. Will be conducting further evaluations based on this model.

nope that sounds about right...

So with a high flow 21U I wouldn't have to bend the stock water lines like I did when I fitted the SS1PU?

Just trying to work out my options for my R34

I have an SS1PU to transplant into the r34 but I don't want to go through the issues I had with the oil drain and the water lines.

Then I have to get to that water line behind the block. I tried to get to it last time and just couldn't figure it out. Also if the new 21U is better than the SS1PU then I may as well upgrade if its easier to install.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
