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?

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.

check this thread:

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...

Good Luck with it.

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) :)

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!

OMG. u're in japan! Can u get me some parts? - I hear 18" rims r only $400/$500 there 2nd hand. I want some! lol.

Back to ur question. my bov did the samething. after like 2 weeks, i reset the ecu once too, everything was fine. Guess i was just lucky. anywayz how about those rims :) I'm pretty sure there will be a few guys in Japan who can help u out - $ is an universal language of requiring their services.

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
