I always thought running flat tops means u can run more lift.

comp ratio going to be around 7.8 to 8.1

reason that low comp - less pinging high boost ,

makes more power then high comp - all types of fuel

I notice a lot of high comp boost rb have head/studs lifting issues

allways prefer low comp high boost/ high comp low boost

I here'd about weathering/seasoned blocks are better for hp than new block for cast iron - new block will move and flex up until 100,000km

Idea is the hot and cold temp stop the cast iron from expanding/ flexing - taxi blocks would be good idea

I left the rb30 block outs side for 6 months bare wit the girdle and just befor sent to engine shop I went to cryogenics

I believe this theory works , some might disagree

crank wouldn't think be any benefits

only cost $200 shop in melb -http://www.cryocycle.com.au/

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
