I think the thoery is of cooling issues. The water pipe flashing is awful on these engines done worse than others so the rear cylinders get hotter than they should esp once you start ramping up the boost. Don't quote me on it but I think the plenum has an odd shape runner back there too, meaning it's more restricted than the others. Excess heat plus poor breathing, recipe for disaster esp once you throw in 25 years of aging, a crappy generic chip and some failing components/poor maintenance. Not saying that's YOUR particular issue, just generally. Interestingly mine failed on cyl 3. I know a chap with a collection of blocks, not one has the same cyl failed. Six is the most probe to failure but it's not always the fail point. "Today, 02:55 Noz, sorry, haven't got that far yet, I'll let you know. Rich" Does that mean you haven't done a compression, if so what leads you to the conclusion it's failed?

No likely no lighty.

Haha! Looks like a proper. It's a shame nissan didn't make that section from aluminium.

How did you produce that?

Er, did anyone like, mention helf and saftie mate? Surely there should be a guard at least over the rotating core, you wouldn't run a lathe like that...otherwise interesting stuff. Sorry I didn't tb yesterday gaz had a day of it.

Mine was a daily when I first got it. Rather uncivil by when it broke as fixing it can take time. Much prefer having it as a toy now.

Have you confirmed that? So many are supposedly later cars and turn out to be early ones.

Odd I'm not the only one who had that UK JDM difference lodged in the brain it's been mentioned many times on here. Anyways at least that's cleared it up. Decat away.

It should pass the emission limits regardless should it not? And that doesn't appear to take into account the presence of the cat? As lack of presence can be a fail in certain scenarios. I was always told for uk cars pre 93 and JDM 95 we were fine. Is this incorrect?

To clarify that JDM cars that are pre 95 are fine to decat legally. I posted that before you asked about uk cars. Afaik uk cars are on the database so therefore it's only upto 93 you get away with it, grey imports arnt on the database so are tested as precat. No tester has ever even mentioned it with mine.

Do a boost leak test, a properly sealed system will help lots with reducing lag as well as being important anyway. If it feels overly laggy I bet it's leaking. Beyond maintaince, breather mods work well reduce lag and increase effecientcy, the ultimate is to have twin in takes upgraded intake and intercooler piping, 2.5" outlet intercoolers obviously larger cores too, divorced 3" expansion downpipes and test pipes with 3" cat back. You will of spent a few quid by then though. A set of 2.5" divorced downpipes and test pipes with the catback made a big difference in response.

Cat eligibility varies between JDM and UK cars as well. Mines an 89 so no probs what so ever.

How big can you go before you have to notch the darn chassis rails?

Renting to students has got to be a false economy, I've seen some horrendous stuff. That being said I've seen the behaviour of millionaire renters too. Shocking lack of respect.

Happy birthday bud

I don't think it will grow like that for a long time, it was unsustainable as it was. Massive prices that people at the bottom couldn't access stagnates the market. I'm a little confused as to how I'm going to afford my next step up the ladder currently. Everyone said once your on the ladder it's easy but the next run up seems to be quite a leap...

Through Z1 the gt600 kit is cheaper than the gt535s... There's about 100 a side difference if you choose to make your own kit, the 535s bring the cheaper, or gt2554 as they are called by garret.

I'm not qualified to answer that tbh mate. The 600s are what I want. But as Noel said the other week he mapped a car on stockers that was on 600s it made 50 less hp but more torque and a better power curve. Maybe your better of spending what you save by not buying new tubs on manifolds and breather mods? Up to you isn't it really.

House prices are shifting quite swiftly here at present.

Do you guys recon there are less opportunities to make your money work than say 15-20 years ago?

Do you know when it starts making boost? I'm guessing very low down?

Genuinely good points tom. It's not so much what's too fast but what's acceptable, ie input for output. Not just financially but logistically, the more highly strung you make it the more fragile you make it, theoretically of corse. 450-500 fwhp on the road and on tsp in a useable powerband than 1000rwhp that arrives in one lump chewing the best tires you can afford to pieces before spitting it's dummy over a fly it just swallowed, I'm being pedantic but you see my point. I've read from several people there car was more fun at 500 than 600-700 simply because it was less hassle.

Decats would be a worthwhile choice.

I think the fact they are so unrestrictive in comparison to stock is a big factor. I don't think at that point the MSP ones were out
