New Gtr Owner

[2510s]

Hi all, i'm new to the forum and also new to GTR ownership, so thought I might share my new ride. It took me 6 months to find this car, but it was well worth it. I'm a mechanic and have owned 24 cars, mostly imports so I knew what I was looking for. Compared to most of the GTRs I had looked at this car is immaculate, with no accident history, no rust, has been well serviced, hasn't got a rattle or squeek in it, and has some tasty additions to boot!!

March '90 model

110ks (genuine as far as I can see, belt changed feb '03 @ 104ks)

Black

17' work rims with potenza g3s

HKS ball bearing turbos (I think 2510s)

HKS split dumps into full 3.5' system

HKS oil cooler and remote filter setup

MINES retuned ROM

Possible cams and/or adj. cam gears

Straight off the boat pulled 228kw at all fours in shootout at 1.2 bar, but it doesn't make that boost till 5500-6000 rpm even in 3rd gear.

I know it needs some form of boost control (has restricter removed)

but any suggestions as to why it takes so long to climb onto boost will be welcomed. My tuner also suggested it may have a full MINES built motor, as it is painted in a goldy/silver hue, apparently their colour. The compression of 160 accross all four, HKS gear, no oil leaks and lumpy idle may also support this idea.

Anyhoo, any feedback on my boost issue would be great, cheers!!

Sounds like a nice car.

You should probably ditch the mines computer and have the car retuned in for aus conditions.

My car just has exhaust, power fc and boost controller runs 1 bar, it makes 227kw at all 4 wheels so your car should make more at lower boost. If it was retuned it probably would.

160 compression across all cylinders is very healthy but if it was a rebuilt motor in the last couple of years then you would be expecting comp rating around 180. I think mines use a dark blue on their rebuilt engines.

I reckon get new ecu and electronic boost controller, have it tuned and that car should be apples.

Yeah power FC already in the pipeline, along with EBC, just $$ constraints.

2510's and lag till 5000rpm in 3rd doesn't sound right at all.

people with 2535 or whatever they're called don't even see that sort of lag.

from what I remember, the 2510's are actually smaller than N1's aren't they?

and people with N1's basically say it feels almost like stock but with much better mid and top ends
