    Yeah springs and a ras kit are 100% required as far as i am concerned as it was valve bounce that ultimately killed my SR ... er the first time around..cough...

    Opinions vary, but I never took my standard engine above 1.2bar on a 2871, i went forged engine, MHG, etc and OS Giken box to run higher boost. I also had 740 injectors. Component limits are not always exactly like for like, and it's playing percentages i agree, but the more power you put through standard parts the more you increase chance of failure.

    I prefer to do something once, and do it properly, i find that is also more cost effective longer term

    Also, if you are close to HDev you are going to struggle to beat Jez for sx knowledge, i'd go nistune and take Jez's advice.

    yes Jez owns HDev i think, and has one of the greatest knowledges on the SX, I have driven down from the northwest several times for his work and mapping, so it's a no brainer if you are that close I've had good advice and tuning services from there for over 15 years, as have many of this forum.

    There are different specialists in different regions, I've travelled about and used most of them over last 25 years.

    But if you get stiff springs your vvt will most likely start to rattle very quickly.

    You don't need cams for 400.

    H-Dev do bespoke mapping.

    A Power FC may be old, but it is an inexpensive and reliable way of achieving good figures.

    Pick your tuner and then an ECU to suit them. Better an average ECU with a great tuner than a great ECU with an average tuner.

    Two things,

    H-Dev isn't in Horsham any more, but definitely worth the drive, I'm from Sussex too and drove down there to get mine mapped by them.
    I have some 740cc injectors for sale if you need any, they have been professionally cleaned and I brought them from H-Dev when they mapped it. I'm now running 1000cc injectors.

    Yeah VVT is a pain, could just go a ras kit then - wont affect VVT but will help save your engine from... well just have a search for my dead one... snapped the timing chain and everything.

    Wish it was, as closer to me than he is now...

    Still worth the trip though, they know Nissans inside out, or try Abbey Motorsport, they are in Surrey.

    £245 posted for the injectors, I've just had them cleaned and flow tested at Abbey Motorsport, the cheapest I've found them online is £429.

    Is it really? I never knew that?! I'm sure they were in Horsham at one point.

    I think he was in Newbury when I first started going, I think that was the original location.
