NGK's are as good as Denso's. If they are new and a tenner then yes I suppose they are worth it!

I had a civic, and found that the gears where very fast and unlike the linear power delivery of the ZED you get an extra kick at the top end. On paper the S2K has less power (40 less than DE, 60 less the rev up) less torque (60lbs/ft) but does weight a small 285kg less

The Zed will get to 62 between 3 and 4 tenths of a second quicker and has a higher top speed as the S2K tops out at 150mph.

There is a youtube video of the japs testing the S2K, 350z, R34 GTR, M3 and Boxter (2.7l) was around 8 laps of a track in Japan. R34 was first followed by 350z, M3 (maybe biased not driving as fast ) S2000 and finally Boxter. As said before, very different cars, just depends on the driver.

One small point from the above, the S2k has far more than 60lbs/ft difference between the Zed. The S2000 has no more than 160 lbs/ft wheras the Zed has at least 100 more. In fact, the Zed has more torque on tickover than the S2000 has at peak.

All I can say is have a good test drive in both. Both are excellent cars that goes about giving its thrills in quite different ways. Neither is a bad choice, it depends more on what you actually want.

I didn't add Molyslip to mine and used the standard Nissan oil for both the box and the diff. Huge difference.

I used the Nissan oils as with the 200sx box they were generally regarded as the best to use for smoothness so carried this logic over.

Just changed the gearbox and diff oil on mine and it feels sooooo much nicer! The whole drivetrain feels smoother and tighter. Much better and I can't believe the difference it has made.

Enjoyable meet that one. Glad to meet new people from both forums.

I've got that set up - makes the sound less deep and more raspy which is good in it's own right. I'm positive it made it perkier and more free to rev too - more eager. Soon I'm planning on a Y pipe and UpRev to help it along some.

EDIT: Just remembered it has headers too!

Also, it's neighbour not the American way. Go get 'em!

Who the heck are Holdcroft? Do you mean Horsham Developments?

Most rear wheel drive cars can be a bit chattery and as mentioned I'd be inclined to leave it until it slips. My last car, a S14a 200sx has the exact same noise from the clutch all the time I owned it (7 years) and that was tuned a bit. It's a side effect of the front engine/rwd transmission layout.

I would argue that you don't even need a full exhaust, just some hi flow cats/decats and a 'Y' pipe which joins up the exhausts from the two banks of the 'V' into one. The back box flows well enough. Few traders on here can sort you out with something suitable.

Horsham Is a bit closer to you and Jez is also excellent with his computer gubbin wizardry, worth considering.

The judder is the dual mass failing. The slip is the clutch plate failing. The dual mass element can fail long before the plate gets worn and cause juddering before slippage.

Take it to Avia Auto's Bridgend. Best aligners in south Wales!

Standard ST would be slower than a Zed. ST's can be tuned easily though so when the power to weight and torque to weight ratio exceeds that of the Zed, then it will be quicker.

The ST would probably feel quicker standard, but wont be.

I went, really enjoyed the bands but the overall site layout and logistics spoiled it for me and was highlighted by the rain and mud. Probably won't go again.

Mine is a second car for the weekends. Having another car helps keep it a little bit more 'special' to drive.

I got some Bosch Aeroblades and they are ok up to motorway speeds. However, they are terrible at motorway speeds as they just smear the water on the way down to the park position.

Has the angle of the lights changes so that they point straight down? If so, your height adjuster is playing up, located near the arb droplink on the passenger side (IIRC).

If the lights are just dim then new bulbs I guess.

Having run the FK452's and the Hankook Ventus Evo V12's I'd say the Hankooks were the better tyre by about 5-10%.

its def 102 because he needs it for he is close to a race track and supplies a lot of the competitors.

And it costs £1.44 a litre???

If it is then get as much as you can! It used to sell for about double that and I haven't seen any for ages.

I still think it is 97 as I know there is a shortage of decent superunleaded in Northern Ireland. The raceers probably use octane boosters on top of that.

I very much doubt that BP Ulitimate is 102 RON!!!

BP did do a 102 RON petrol, but that was ridiculously expensive - around £2.50 a litre.

BP Ultimate is 97 RON.

I filled to brim last night when DTE was showing 27 miles - it usually goes to ---- at 20 miles on mine, I managed to get 68 litres in so 12 litres left in the tank. At 5 miles per litre (conservative) that is around 60 miles.

With the dirt in the tank issue, of all the modern petrol tanks I've looked into it is very very rare to see any kind of dirt. Usually they look brand new!

OR they would going faster than 100 at the quarter mile point?

I know what you've had, I've been over on sxoc myself for 7 years! Point is MY standard Zed is slower than my stage 1 S14a. When I've done the typical mods and uprev'd I'll speak again. However, I don't think the circa 300hp Zed would be THAT much faster. That would make a power to weight ratio of around 197bhp/ton, whereas a stage 1 S14a has a power to weight ratio of around 220 bhp per ton.

I know there is the 'area under the graph' and off boost, the zed would murder the 200, but on boost, the S14a is definitely more thrusty.

This is a pretty good site and seems accurate.

Looks like you'd need around 325 bhp to be equivalent in sprints compared to the stage 1 S14a.

The Zed feels a fair bit slower than the Stage 1 S14, and is probably a second slower to 60 and 2 seconds slower to 100. Also, the mid range punch is missing. Saying that, the Zed handles better and is more liner. That means you have to be in the correct gear more often.

 

Recent "comparisons" at Donington showed that a plenumed, decatted Zed is actually roughly par with a Stage 2 S14 as far as acceleration goes ....... possibly better going up hills

 

Keyword there is FEELS Even when s/c my Z felt slow compared to previous car. N/A cars will always feel slow compared to a turbo car, thats not to say they are slower though

It is slower though, the stopwatch doesn't lie! The S14 could do 5.0 second 0-60's and 12 second 0-100's. the Zed does 5.9 0-60 and about 14 second 0-100's. It's gonna need more than the typical NA mods to accelerate as fast as that.

I've been in slower stage 2's compared to my stage 1 and I've been in very rapid stage 2's. If we are looking at 300bhp and similar torque for stage 2, in a car that weighs 250kg less then the laws of physics can't be bent that much!

Don't use oil additives under any circumstance! bad news and a waste of money. Fix the problem at hand, don't disguise it.
