Ok need some help on installing my sparco 4 pt harnes.

Just wona know were people have mounted the eye bolts so that it complies with cams.

Was going to use the stock seat mount points for the sholder strap and r/h lap strap and drill in to the tunnell for the left hand strap.

the other thing is i wont them to be easy to access to so i can remove it when not in use.

pics would help.

You should be able to use the factory location for the side straps on each side.

The shoulder straps on the other hand won't meet CAMS requirements if you use the rear seatbelt mounts, it is too far down. The safest place to mount them is at parcel shelf height, but the parcel shelf itself is not srong enough. Best idea is to buy or make a "harness bar" if you don't have a rollcage.

I am 184cm tall, and I have adjusted my seat to a decent distance from the steering wheel, not like a Chapel street cruiser, and the angle from the seat to the rear bottom seat belt bolts from the horizontal is 38degrees - and CAMS states a maximum of 40deg, and with 0-10deg being a recommended range.

If a driver is shorter chances are his seat will be even further forward, hence the angle will be less than what I have.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
