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

Not my sort of thing but I can appricate it for what it is. It's a far more sensible track toy than what most of us would choose which makes more useable, more use, more fun...also I'm guessing there are more events that it would be eligible for in comparison to say sonething like a zed?

"Because the manifold is so short and the pipe is so thin, the manifold gets hot really fast.... This offers amazing spool up, but the problem is you can only bend a paper clip back and forth so many times before it breaks....." Ie they are great for performance, poor for longevity. I'm not worried about longevity. I tell you what the response generally on here over these the person who did but them will be handing them over for a £10 note lol so cheers for that.

Can't say it's something I've seen myself, are you sure it's a boost sensor? Maybe it's not stock, a picture might help.

There's only 2 stock boost solenoids as such which are down on a brass plate on the turbo, they look like this; Then the actuators for the wastegates on the turbos themselves; You have a loop these two are within this which is how the safety boost works. The EBC tricks the actuator to seeing less pressure, this opens the gate later and at higher overall system psi. Some have only one solenoid on the EBC so you take your two Wastegate feeds the 6mm ones Tee them equally and run a single to the ebc solenoid. Like this it's the yellow lines your interested in currently and your boost sensor for the dash is in the other side as that's an American diagram; If you google robos 300zx page there's loads if diagrams and write ups that will help you.

Sorry "not" to utilise them. That's exactly my point, my mate looked at me very squiffy when I was trying to tell him they don't work long term on zeds. I don't think he believed me since like you say they are standard fare.

Yeah or a brand new Stanley.

So if anyone has a set in their shed cracked or not let me know :)

Several companies have made them and ceased production, due to the cracking issue. One reputable stateside company went as far as making them from inconnel with the same results sadly. Tubular manifolds are extremly good at flowing gasses which is why the zed is one of very few cars to utilise them.

Cost vs performance gain. It's for my temporary engine, I wouldn't entertain them as a fit and forget item but in my scenario I can pretty much consider them disposable if necessary, I can just weld up the cracks if necessary.

Yes they did lol, few pence more they would be mine. Oh well back to alibaba they arn't much more than that on there new. Alibaba is confusing though.
