Is vct working correctly. That looks like pretty lazy response.

If im honest i dont know whats up.

Dex is unsure also. Dunno where to go from here... Will give it a burst at the drags and see what i think

Well i cant take a trick.

Took both cars down to the drags sat. And both went poorly!

The torana had 2 runs in and on the second run broke the casting around the alternator and had to coast it home as it was getting hot.

And worse for the Skyline. 1st gear and second gear ran beautifully. But as soon as you but it into 3rd, or 4th, it coughed spluttered and backfired. No acceleration and breaking down something shocking. needless to say nearly $1500 worth of tunning and its still not right. Unsure what the problem was...

So the torana ran a 12.1 which was shocking and the skyline a 13.5 which again was no where near it for either! Only positive is 13.5 isnt bad for coasting from just over the half way point... hopefully see a high 11 out of it

Back to the drawing board tho!!

Without reading anything in the thread. Main reasons for it being laggy.

Exhaust restriction, cam timing, poor tune, VCT issue. It will most likely be one of those.

Thanks mate, will take it somewhere else to get a second opinion on tune etc.

haha defs not an exhaust restriction as it only has about 3 feet of exhaust

Long time coming but i got the car tuned, again. This time by a different tuner and to say it was tuned badly seems an understatement.

Havent had a chance to take it out to the drags again but have a drift prac day coming up in 3 weeks i think, so will test it out then

attached the new dyno print out

Well took it drifting sat.....

could be over kill for me trying to learn lol...

Jumped in a few other cars with much less power and some MUCH more responsive and made learning easier.

But damn was it fun / fast!

The clutch either let go at the end of the day or the spoigot is sticking or something. so will have to fix that. but the poor little thing got a hammering and ran well all day.

The tidy up will start soon. trying to source a r33 gtr front bumper and also some head lights....

Will post pics as i can find them

    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
    • Neg, the top one is actually for the front. The sizes are 18x10.5 +18 and 18x11 +32.   I measured many times but I'm sure I'll have problems as this is the thread for problems.
