netrati Posted June 25, 2003 Share Posted June 25, 2003 Hey I got a few questions for you guys. I just bought a 1989 GTS-t. It has aftermarket exhaust, intercooler, intake, bov, and tuned computer. The deal is it idles kinda rough and when you let off the gas after revving it up the RPMs drop way low like 450 or so, it almost stalls. Another thing is horrible, I mean awful performance. I tested it from 0-100km/h and it took 8.869secs!!! Not anywhere close to stock! I'm hoping that it needs a tune-up really bad. Maybe a fried spark plug or a bad ignition coil. Could one of these things cause the performance to be that bad? Link to comment https://www.sau.com.au/forums/topic/19141-horrible-performance/ Share on other sites More sharing options...
SLY33 Posted June 25, 2003 Share Posted June 25, 2003 your nearly stalling problem after revving it up is due to the BOV. the spring tension needs to be increased a bit, simple fix if your bov is adjustable. Sounds like you need to get a good tune - theres no way you can be in japan?! why on earth would you need advice from australia? And you no write broken englis.

netrati Posted June 25, 2003 Author Share Posted June 25, 2003 HAHA very funny. I'm not for sure if the BOV is adjustable, it's an HKS one. I'm an american that's why my english isn't broken and I can't exactly get help here in Japan b/c I don't speak Japanese. I hope a tune-up does the trick.

netrati Posted June 25, 2003 Author Share Posted June 25, 2003 Can someone explain to me why exactly not enough spring tension in the BOV causes the car the stall after high revs?

BigDatto Posted June 25, 2003 Share Posted June 25, 2003 check this thread: http://www.skylinesaustralia.com/forums/sh...s=&threadid=408 curiously, changing to copper plugs gapped @8mm fixed my stalling problem - so it seems it could be any one of three issues BOV, fuel pressure or in my experience, plugs ! must be difficult for you not speaking Nihongo...

Cool Hand Luke Posted June 25, 2003 Share Posted June 25, 2003 When your car idles, do your revs fluctuate? By that i mean for 15secs its at 800rpm, next 15 secs its at 1200?

netrati Posted June 26, 2003 Author Share Posted June 26, 2003 No the revs don't fluctuate that much. When I first turn in on they are usally high, somewhere around 1200RPM. After a few mins when the car warms up they drop down to 800RPM.

Steve Posted June 26, 2003 Share Posted June 26, 2003 netrati, have a look at this thread: http://www.skylinesaustralia.com/forums/sh...s=&threadid=408 could also be the problem at low revs. Plugs never hurt, esp as NGK coppers are about AUD$20 a set, clean your afm, change the fuel filter and reset the ecu - different car (hopefully) Link to comment https://www.sau.com.au/forums/topic/19141-horrible-performance/#findComment-402627 Share on other sites More sharing options...
netrati Posted June 26, 2003 Author Share Posted June 26, 2003 Got the car back from the shop today. It seems as though my mine's tuned computer bit the dust and it was only firing 5 cyl.

Nick Posted June 26, 2003 Share Posted June 26, 2003 I had dramas with the previous owner's adjustment on my Blitz BOV, a simple tweak and she was running sweet. But now that I've just plugged in the Power FC (yet to be tuned), yeah I get higher revs when first turning the car on (like 1400rpm), but it rarely comes back down to where it would ordinarily idle wehn warm on the stock computer (700rpm). And when decelerating coming up to a roundabout for example at 30km'h in 2nd, as I exit the roundabout my revs will rise and I can actually increase my speed without touching the accelerator. I know the base program is not so great - typically running rather rich - but is the car feeding more fuel to the engine and at the same time being misread as throttle when the clutch is out and my foot's off the accelerator? WTF? The mind boggles. There I go, having a spit when all it probably needs is a tune... Anyone ever experienced anything similar though? Cheers!

netrati Posted June 27, 2003 Author Share Posted June 27, 2003 HAHA probably not even $400. Cars are super cheap here. There was a 1991 Skyline GTS-t with an aftermarket turbo, exhaust, clutch, injectors, pump, and all other kinds of stuff for $4800.

Ronin 09 Posted June 27, 2003 Share Posted June 27, 2003 i think i offer a collective "we hate you" from everyone here in Aus who can't get a modded GTSt for 4800.
