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

      Mistakes were made, my R34 Story

      By GTSBoy · Posted

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      By GTSBoy · Posted

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
