Cat Delete Pipe, I bought this pipe for my R34 but have just dicovered that the flanges are the other way round on R34's so it wont fit. If you have an R33 or R32 I'm sure it will fit fine. Just unbolt the cat and bolt this in for the track. Illegal for road use. 3 inch flanges Looks well made. Cost me $60 plus post. $50 R34 Gtt Triple Gauges, We all know what they look like. $300 R34 Gtt Clutch And Pressure Plate, Suit rebuild. Stocker with lots of k's on them. Would be a good Jim Berry rebuild. Upgrade now and sell your stock one while it's still perfect. $50 Stock Panel Air Filter. Suit any Skyline. It's stock. It was on my car for about a month when I bought it. Look brand new. $10 plus post if necessary.

I bought 4 semi slicks 235 something 17 and never got around to using them, now they're too old to use. I bet they'd smoke up real good. I need them gone this week or I'm throwing them away.

pm T04GTR on this forum for an almost new second hand one.

Well for a start those graphs show boost - not AFR. Your boost is dropping off to 9psi. What boost controller are you using?

I understand.

You're a champion. I need: 280x155mm (x2) 280x50mm (x2) 180x155mm 50x161mm (x2) Sending a pm too.

At least you're back on the road.

Yeah but no one listens to you.

Hey Shonen, You have my number . Compression ratio on NEO's and non NEO's are both 9:1 so no difference there. Are you putting cams in? CAMS will lower your dynamic compression ratio and raise your detonation threshold. They also help you by making the power you want with less boost. As long as you keep a close eye on your knock levels you should be fine. Learn how to knock a couple of degrees out of the timing on hot days with the PFC. The other thing is to make sure your boost is stable and not overboosting. If something isn't quite right, think hard before you touch anything. I would have to say that with all the messing around with my car lately, if I didn't already have forgies then I would have blown my engine at some other point anyway. This is because I fiddle and do some work myself.

There's nothing wrong with understanding why rather than just picking something that empirically appears to work.

I'm torn. I have a partial CES system (with the rest Fujitsubo) and it works great but you're right about having money left over for other things. Shit, there's enough spare cash for a set of cams there. I voted mild steel xforce but it's a tough decision. I would think that you will end up within about 10-15 rwkw from worst to best but maybe run less boost on the better ones. This should mean less stress on other components and some minor fuel efficiency gains.

I remember this argument has been had on this forum a few years ago and a couple of highly respected forum members (not naming names but I remember ) didn't believe it was possible but the proof exists. All it means is that it's difficult for people to definitively figure it out with the limited resources all of us have here. Once the theories have been proven or disproven and sufficiently published some of us will understand it but right now we have proof of the phenomenon but none of the reasons.

Depends what brand they are but when you increase the bore size you increase the compression ratio. Are you doing any head work? I had some fairly minor head work done, 87mm pistons, stock thickness head gasket and ended up with 8.75:1 CR. Which I quite like. It's almost as high as stock (9:1) so the responsiveness is there but being a fraction lower I think makes it easier to tune and a little safer with regard to detonation. Basically I told the engine builder what CR I wanted and he worked the head to achieve this with the chosen pistons and head gasket.

And Sydneykid says: My rule of thumb for volumetric efficiency on a DOHC 4 valve engine is 90 to 95% depending on what's done. A fresh engine with cams and porting etc is closer to 95%, compared to an old engine with stan'd cams and cast ports that would be closer to 90%. Simple

I blew my single and no other damage.

How do you know they are 100%? What gaps are you running? Also do a search for misfiring or look in the forced induction quick referrence.

Get a second opinion.

Nissan sell em. I have one at home somewhere. If I remember I will look at it.

I'm black.

Doesn't bother me. Whereabouts are you roughly?

UAS keep a fair bit of stuff in stock it seems and Powerplay a bit too. Depends what you are looking for really.

Already happening. Should be ready soon.

That was great fun. I cheated and still didn't win.

I think I'll head down for this.

Yup, great fun day. It's also so relaxing to go to a track day and only have to organise myself. Tried out the new diff. Was up to 2:30am the night before putting it in at Majanals place in the mountains. It definitely changes things. I came down the straight at about 200km/h, stabbed the brakes for turn 1 then a little gas to turn 2 but was too much because of the diff and lack of rear end grip (my semis have had it), so at about 160km/h I spun around and off into the kitty litter. Had to get towed out but no damage. That's my first big lose ever on the track. Kind of fun although I would have preferred to do it at a slightly slower speed. Also enjoyed taking the mighty MADGTR for a spin. The GT-SS's really are great on that engine. It almost feels like a non turbo it's so linear. You really feel the extra weight when braking but the grip is unbelievable.
