dunno if this is the best place to ask, but here goes...

My friend's S14 is jerking like hell on every gear change after about 3500-4000 RPM. I drove it myself yesterday to see what he meant. Basically, that's all it is...a jerking that doesn't really allow the engine to go up to 5000 or 6000 RPMs. He has taken it to a few places and they've said a number of different things ranging from broken hydraulic lifters to oil clogs.

Can anyone suggest any other possible faults an SR20DET could go through? The car used to make 315rwhp, but all the good stuff had been taken out prior to him getting married. The car only has a cat back exhaust and an HKS bov left, plus the turbo. We're taking the car to my tuner later this week, but would like to know beforehand what it may be.

any thoughts will be greatly appreciated.

Zak

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
