ok, i remember sometime ago reading threw one of the threads somewhere that if you put stock gtr pistons into an rb25de they will fit straight in no probs and they will lower the comp ratio down to some value like 9:1 and would be able to handle more boost but still retaining a higher compression ratio, can all you guro's out there comfirm as i cant find the post atm and theres some up for sale and whilst the cars off the road would be nice to swap em over so i can up the boost a bit

cheers Jarrod

ok i did a lot of sole searching threw the turbo section and it seems like there is a little bit of info in there. looks like if i want to use the 26pistons i need a crank and rods to suit, plus i gain an extra .1 litres yay, havent found any info about comp ratios but i think it says they'll be about the same as a standard rb26 so what like 8.5:1 or something. thinking if i can find a crank cause i've found some roads and pistons i may do it, lol im going to have bits of everthing in my car :blink:.

series 2 turbo shell, series 1 na engine + series 1 turbo parts, gtr pistons crank rods, plus aftermarkets bits mm when i get this thing on the road if i ever do its going to be a compeatly different car than what i started with

    • Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.
    • Thanks for taking the time to post that ! If anything changes or happens please do update us. 
    • Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.
    • Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
