Any suggestion on new injectors? Looking at the Bosch 1000cc injectors. I don’t want to worry down the line about replacing again if I do extensive HP hainsgains

Nice car - and welcome to SAU!

Looks like the steering wheel is still on the "wrong" side for you guys - are you allowed to drive them like that where you live?

I don't think you would ever need 1000cc injectors on an RB20, unless you fit a big laggy turbo and run on E85 fuel?

The new injectors these days can manage a wide HP range much better (ie a big injector can manage fuel OK for low HP) - but what sort of HP gains are you chasing in your RB20?

Checkout the RB20 turbo upgrade thread for info on getting results from the RB20

https://www.sau.com.au/forums/topic/103095-rb20-turbo-upgrade-all-dyno-results/

I have an R33, so I've never looked at the thread.

I'll likely get flamed by the R32 GTST crowd for this comment, but many owners in Australia with an RB20 in the engine bay look to other engines if they're seeking big HP gains (eg RB25, RB26, RB30, 1JZ, 2JZ, Barra etc).

I'm sure with the right mods you can get your RB20 singing, with ample power for a street car - I just don't think 1000cc injectors is the best 1st step.

cheers

Your car looks mint.

Don't do to much unless you plan on getting another one that nice.

once you start modding it's hard to stop ahaha.

1000cc way to big.

Fuel pump and it's wiring and lines first then injectors. 400 hp is about topping a 20det so you only need the injectors to be as big as gtr stickies 444cc.

Front mount intercooler. (Return flow to avoid chassis holes)

High flow rb25 turbo

Zorst setup

Pod filter.

Bleed valve

Aftermarket ecu

 

That should be enough for fun

 

Start with a bleed valve and don't boost over 12 psi or you will break the zorst wheel

    • 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
