After 4 years, I take a next step and switch engine to fresh builded SR20VE-T with forged internals (Manley, CP, ACL, ARP). Yesterday was first start of engine. After break-in we will see what can afford this setup ;)
I put also some changes in suspension/braking since new engine was build up.
Brakes: 350z rotors with 911 Porsche calipers - yellow powdercoated
Rims: 7x17 OZ Superleggera - gold bronze powdercoated
Suspension: all stock bushings replaced with custom polyurethane with aluminium alloy carriers - http://unitracing.pl/

Yesterday was first start :)

After 500km I found some time to take some pics

Thanks all of you for good word :)

Generally few months ago I sourced cams from stock x-trail gt vet cams. They have much more better timing and lift for boost than stock VE - they are already dropped in.

Shifter bushings also need to be upgraded. It's a lot stiffer but gears goes smooth and much more precise.

Thanks ;)
My project is a little never ending story :D Everytime I think it's finished, I'm found another place where I can provide some improvements. Now I'm waiting for bump steer kit and RCK from 2JR ;)

About competition. I was in september on a little track drive. I was on Mazda meeting but was many cars different makers, such as Opel/Vauxhall (Speedster), Subaru (Impreza), Renault (Megane RS). Wheather was nice, a little to hot - slick grips like hell. I get nice score in single drive: 4th time in general and first in FWD class of the day. In front was 2 Speedsters and RX8 with swapped K20 (Honda) engine with supercharger. So it's not bad for just an Almera :D Getting score on Impreza is for me just right ;)

Shifter bushings also need to be upgraded. It's a lot stiffer but gears goes smooth and much more precise.

Where did you get these from?
The Custom Steel bracket/bushing from the USA isn't available anymore.
This looks like a decent replacement.
vvl- ma jeszcze ten extra dźwięk pompy oleju co jak kompresor słychać ,ja już vvl-a dobry rok upalam tylko w n15 i cały czas mnie o gęsią skórke przyprawia :)
Moja pompa nie pracuje głośno ;) może masz coś z rotorem? :p

Myślę, że warto uszanować innych użytkowników forum i pisać w zrozumiałym dla nich języku - keep in english, it's not our polish backyard ;)
For me it's working smooth and quiet as any other SR pump. This sound is rather coming from cams and solid lifters ;)
Nice project! Was it hard getting SR20VE motor in Poland? I'm myself from neighboring Lithuania and thinking of n15 SR20VE project, although the main problem is sourcing the engine itself.
