You should put my inlet specs on there too.
264 degree cam regrinds + valve springs

I will. Have to grind the cams before I can measure them to graph first

Haha. So are you putting motors together today or grinding cams? Did PK take the bait?

I've ground one. But now onto other things. Ill get more done later today hopefully.

Hopefully a local Christchurch VR4 owner will be getting me to do his cams for him in the not so distant future. So should be able to do a writeup soonish.

why does that matter? the part number of the stock springs is irrelevant as the springs I supply with the regrinds are supplied because they are the correct size and spring rate to suit the cam profile. Its actually a Nissan RB26 spring kit as the springs are the same size as the Evo/VR4 spring but come in kits of 24 not 16 like the Evo kits do.
Yes that doesn't matter at all. My friends have managed to use stock springs in their evos (HKS 280 cams). I was just thinking that I might want to go with stock springs first and save those springs for the new, better engine. We were just yesterday looking at evo and galant heads on the table. Maybe evo stock springs are a little better than vr4 stock springs?

using stock springs on a 280 cam is a terrible idea! without the appropriate valve spring on a large cam like that the valve train can get out of control causing damage. Just because they have done it doesn't mean its a good idea
Don't bother with stock evo springs. they may be stiffer than the VR4 springs but they won't be anywhere near as good as the ones I am supplying you.
Run the springs I'm supplying you, If you didn't need them I wouldn't have sold you them, you can always take them out and put them in a different motor later if you need to.

Evo stock springs was never an option. Was just thinking that if they lasted in an evo engine maybe they would last in an vr4 if they were the same in the first place. Well they weren't, and propably evo ones are stiffer like you said. As we all know changing those springs while engine is in the car is a pain in the arse.

yeah changing them is a pretty big job but doable in one day with taking the engine out and back in again with new springs and cams. I have done this a couple of times now
Got everything ready now but my mechanic is on holiday for next week 
New cams in place. Engine running fine (couple of lifters making noise). The same settings with ecu give me very little power howeever. The lifters aren't the problem (possible phantom knock). More likely that i need more advance but how much.? Can anyone who has tuned these cars give any info. Im running about stock advance now.
jungle: I know that but I could do with an advice that what should i do to timing. Fuelling is correct right away. Im driving with ethanol. I have stock timing maps +2 degrees right now and evoscan estimate was around 390 bhp where my last setup was about the same but higher torque (reduced from high 500 to low 500). And i can feel it myself that engine is missing on power. So the question is...more or less timing????
Ah ok Lauri I got the impression you were still running stock timing/timing.
How much, you can't really tell unless you're on a dyno.
Well you can but its only really verifiable on a dyno.
If you have ECU flash then you can do it your self as long as you've got an accurate AFR gauge.
You said you've done some logging with evoscan, what load and timing and fuel are you currently running?
