GTR problem

[Guest]

Another thing is it may be running the older style of Link G4 boost control called open loop.

This basicly gives the boost soliniod a duty cycle basied on the RPM, but on the road and in the higher gears it can over boost.

The closed loop boost control is in the latest firmware ( and has been since about november last year) this would fix the issue once its dyno tuned to suit.

That wastegate is too small. i would be fitting atleast a 50mm, or look at running duel 38s

The family that owns Gun City have like 10+ GTRs, they often import them and flick them off on TM.

Favourite job I saw on one of the gun city cars was "hmm, it's going a bit lean, needs a bigger fuel pump. OR we could just cable tie this spare 25t fuel pump lying over here to the pump cradle... and use this brass T piece to feed into the fuel line... Yeah that'll be fine". If it works it works I guess.

I used to live not far from their place, sometimes you could hear the sweet sounds of a very angry skyline getting opened up for a veeeeery long time - lots of long straight roads north of chch

My only suggestion would be if your friend can afford a GTR, especially a reasonably modified one from Gun City (who aren't known for cheap GTRs) then they surely can afford to look after it. Take it to a reliable tuner and get them to check it out properly and then put it on a dyno to check everything thoroughly.

And if they can't afford to do that, they should sell the car before something expensive happens to it and its left as a rather heavy paperweight.

This could be said about half of the performance car owners, (and even some owners on here)

Yeah but you try rebuilding an RB26 and see how much change you get out of 20k compared to an EJ20...

But yes, I agree. Don't buy a performance car unless you can afford to fix it!

TBH if i had a RB26 to rebuild, I would go RB30 conversion. 20k could get me a bomb proof short block.. And i would already have a RB26 head...

Thou 15k only buys the heads off my last 1UZ race motor....
