Hey,

Recently had the car nistuned. Z32 Computer etc.

Car is now running 200Kw atw safely with no ping and good afrs. Required around 14+ psi on stock turbo. Yes im aware of the risks involved. In the past with a remap it ran the same with 12psi but developed some pretty bad detonation. Too much timing apparently and this had to be retarded considerably to achieve similar output without ping (is was being tuned on a hot day too, bout 30 degrees +) But the boost required to achieve 200 ATW seemed a bit excessive considering what others have posted...This engine seems to really dislike advancing the timing...

Ill be highflowing the standard turbo very soon the question is..... running the SAME pressure (say 14 to 15psi) with a highflowed turbo as opposed to the stocker, should i be expecting any sort Kw gain?? or it simply just assuring no turbine failure?

Looking for 250Kw ultimately. and i cant see how an extra 3 or 4 psi is gonna achieve that

r33 Gtst Series 2

85k on the clock.

So altering/hi-flowing the turbo and no tune?

Who knows, could be a dead motor.

As for once you have a tune - how much power is made, purely relies on the hiflow itself, what wheel combination is chosen and so on

hiflowing the turbo and having it tuned to suit.

dead motor. how so?

yes, kw gain. the highflow should be moving more air. ie. more power (with suitable tune etc etc etc)

also consider injectors. its asking a lot of the stockers at 250kw, if they get there at all.

what are the stock injectors good for usually?

Gave her a bootfull a couple of times on the way home. EBC shows peak of 14.7! dyno showed this spike, and then drop off to around 13 which it holds. Pretty much wheelspin from 5k in 1st. But 3 attempts at that and the clutch feels pretty soft...

if the timing and injection values were set correctly on other load points by a good tuner and if the car was treated to a new turbo, then chances of it blowing up is quite minimal, no need to dramatise :blink:

most tuners just focus on the map trace and ignore other cells, hence sometimes you get ridiculous knock going up a hill or down shifting.

if a tuner smooths out the ignition and injection settings for everycell on the map, then there is no need to worry for such a mild motor.

For example with the stock turbo you're only hitting rows 16, and with the aftermarket one you're hitting rows 17 on the load map, and if only rows 16 and prior were tuned, then you'll have a problem.

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
