If it truly has full boost at 3k I really doubt it'll make over 250kw

garret who have far more engineering experience can't even make a turbo that does that, sorry to be negative but I just can't see it being true.

See turbochargers engineered in this project are solely for RB25det engines, Garrett would make a turbo to suit a variety of engines. There are room for improvement when designs becomes specialized.

At moment it feels like some where around the 280rwkws mark with very steady torque. Its drives very differently to any other turbos I've engineered or experienced so far. I'm expecting an out standing result.

If this turbo makes 280kw with full boost at 3k I will buy one in the near future, providing it holds the power to at least 6k on less than or equal to 20psi.

This will be a garret killer if it makes those results!

my current highflow makes full boost at ~3k but only makes 240kw on 18psi, so if I can get 40kw over that with the same response, holy shit!

What are the main engineering differences with this turbo over previous designs ?

Always watching Stao's progress, keep up the good work mate.

full boost at 3k and 280rwkw+ may be possible as thats exactly what I have now... just with a Garrett stamp and a slightly higher price tag.

Dyno sheet please

NA + turbo does not count.

Nope - nothing special, no E85.

tuner said not much difference between what he has seen with normal turbo motor and the slightly higher compression NA with my turbo.

post-36975-0-72596700-1311255208_thumb.jpg this was with a bleed valve

Decent power for the street, very useable... as soon as I touch the accelerator I get boost..

What turbo?

edit: just saw your post, how on earth do you get a GT3076 on boost by 3k? Most people are seeing 3.5 to 4k ? Was that with some ridiculous ramp rate?

The two runs are not equal... There must be some decent load and hold time on the EBC run as it starts at 9psi at about 2500rpm. A normal dyno run should start at around atmospheric pressure.

Second graph looks much more genuine with 18psi at 3500rpm which is pretty much what is expected from a GT3076R with a 0.63 :)

Its a good result :thumbsup: , high comp engine with adjustable cam gears would make a turbo spool earlier. Plus different dynos with different sittings would read differently. Compare to one of my earlier runs using the same dyno:

RB25DE high comp, adj cam gear, 3076 .63 ext gate, with a bleed valve

Standard RB25DET motor, stock head, ATR43G3 int gate, with Bleed valve. My run ended early due to misfire while still making 294rwkws.

They looks similar in terms of Power VS Response VS KM/H. But I know the SS-1 PU is more responsive. :yes:

    • 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
