i also just noticed that you said its a rb30et bottom end, if thats true then having a turbo bottom end with that head i possibly think could be worse than a bog stock rb20, i know its a big call but i think you could've wasted the little money you spent!

They have different compression pistons.

cheers, andrew!

Rb30et is 7:8:1 and rb30e is 9:0:1, he said he didn't touch the bottom end so that leads me to believe he is going to be a tad dissappointed with what he has!

the rb30 et block has oil squirters to cool the pistons.. the rb30 e does not.

Where did you hear this culater?

I've seen both a turbo and n/a block and they were identical apart from the pistons.

I bought the n/a one sitting next to it for $150.

I remember it was mentioned some time ago by some one who confused the bore/rod squirters or what ever they are called with the piston crown oil squirters.

The bore/rod squirters squirt oil on to the load side of the bore.

Not sure of the exact terminology.

the rb20 head has a smaller chamber but has been cc d it also has the turbo et bottem end so it should not be 7.8.1 it should work out around the 8.5 -9.0.1 witch should be great just gotta finish painting my bay then motor goes in and car goes down to boostworks

: >_< I'm afraid you've got it round the wrong way buddy, having the turbo bottom end with the turbo pistons will lower your compression, not raise it. I'd be guessing somewhere round the 7:1 mark which should be interesting to say the least!

    • Resizing injectors in Nistune can be done a couple of ways, and there are a couple of ways that you can make a mess of it. The tuner needs to be really aware of the effects of whichever approach he uses (either K, or TIM). They are both easy enough to "get the injector size right" to run the engine. But little details like old start enrichment and hot start are affected differently, depending on which boxes you check.
    • Pretty safe to say almost everyone that has tuned their own car has experienced this issue. The difference being that we have our laptop in the car and when it happens, it's literally 10 seconds of tuning to sort it.  Would you be happy to plug in your laptop and sort this yourself? It is a very simple process and there is no risk of harming your engine (if you are worried about that). 
    • Yeah thats the next step now, either they wil or i will take out for a drive to work and go straight their after work and see is we get the same issues 🤞  thought i try my luck here too, never know someone else might have had the same issue but thanks for the reply 
    • Basically your tuner needs to drive it for the 30 min (or whatever) to create the same conditions then check the ECU settings and sensors at that time. They may not be excited to because that takes them 30 min rather than just opening the bonnet and seeing the problem straight away.... Hot start is generally not as tricky as cold start, but there would be a table for fuel enrichment vs coolant temp as a starting point
    • Yeah, they all cant say anything for sure as everything is working fine . Said unable to find an issue untill it stops again. Could mist likely be CAS wiring or IAS valve issue but again not 100%
