ok i think i need to clarify iam installing an rb30et

i currently have the 20det loom in the car and complete rb30et loom

can i leave the rb20det loom in to run accessories such as tacho speedo lights heater /fan

if not how much should i be paying to get this done by a sparky

please bear inmind iam not an electrician an although i have a fair mechanical knowledge electrics is where i struggle

The tacho wire u can get the signal from the 30et loom, there will be plug going from the ECU loom towards the dash this is where the dash gets all its signals from, so with a wiring diagram yes you could.

Speedo loom will be seperate to the ECU loom i would think, should have things like alternator, temp etc, this should be easily swapped to the 30et.

Lights etc should be seperate? Or do they run through the ECU loom? If so your option is to remove them from the 20det loom and splice them into the 30et loom so they can gp through the firewall with the 30et ECU loom.

Cant really guess a price on the cost, everycar is different, both being common engine's if you searched could probably come up with a wiring diagram that would help.

    • 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)?
