hi there, just wondering what the deal is with the rocker cover? i think all i've seen have red writing on the NEO and TURBO

-------------------------------------------------------

also is strut bar standard from factory?

--------------------------------------------------------

and i have also just done the solenoid boost thingo is this correct?

I have cut the black wire,

taped over the side of the ecu,

and extended and earthed the side coming from the solenoid.

I have earthed it on the strut tower bolt (front strut bolt), above the strut bar and below the bolt thingo.

IS THIS CORRECT?

AND IS THIS A RELIABLE EARTH?

thanks

What year? I have a 98' which has red writing. If it is running 8 lbs all the time it is reliable enough.

taken it from the DIY http://www.skylinesaustralia.com/forums/in...id=2704246&

sorry, the year is a november 1999 build.

thanks

the engine cover is normal for a later S2,as is the strut brace.

my car is the same.

I don't know about the solenoid wiring,as I ripped mine out and put in a

profec B. they run a bleeder from the factory for a couple of reasons. one of which is to pull the boost level level back if the ecu detects pinging.

Yeah normally the writing on that cover is red. I'd say yours is just worn off or scrubbed off - at least thats what it looks like from the pic. Nothing to be worried about - that cover is purely cosmetic. If you took it off it would look more like the older rb25 (although it is not the same, just looks similar in appearance).

And your wiring on the boost solenoid looks correct. If you dont have a boost guage they are a handy item to have. I have one that I haven't installed yet (one day...). I just connect the hose and run it out the bonnet near the vents (bonnet down obviously) and in through the window - then I can take it for a quick spin to check boost levels. I've only ever used mine for info purposes - as I wouldn't recommend driving and holding the guage this way for diagnostic purposes.

It should hold 7-8psi all the way. If you see it hold 7-8psi from ~2500rpm (stock boost is only 5psi at around this rpm) and upwards then the solenoid mod is working

Its not a huge gain but will give a little more response at lower revs from around 2500rpm to 4500rpm.

The difference is noticeable but you quickly get used to it and want more...

Probably the most noticeable performance mod for a stock stagea is a 3" turbo-back exhaust.

and yes the strut brace is standard. Mine has a stagea sticker on it. I believe they are standard on skylines as well...

thanks for the info steve . I dont have a boost gauge in the car or a spare one laying around, so i cant check the boost levels to make sure its ok. So i'm 'guessing' that it is with this wiring thing done.

Fingers crossed its all good, if not i guess i'll be posting up how i killed a stagea :S lol

thanks again.

nah with the stock boost solenoid it basically just has 2 settings. One is less restrictive than the other - I'm not sure if it closes up fully but I do know that when its "open" its not fully open. It basically just opens up at 4500rpm to bleed off some pressure which means you get a bit more boost (wastegate actuator sees a drop in pressure and closes again until pressure keeps building up again - this time with the solenoid open).

The ECU grounds that black wire at 4500rpm to pull off this little trick. So all you've done is ground it permanently to force the solenoid to stay in its "open" state all the time. The result is that the pressure bleed-off is always there and hence you are on "high boost" mode all the time, instead of just at high revs.

Cant really do anything bad. The worst case is you'll end up with 5psi constantly instead of 7-8psi.

excellent, well took it for a 2second drive around the block, and it does feel a little more torquey in 2nd! mmm... getting a bit worried now, starting to realise the extended potential of the stagea!!!
