:D Even looked after engines can go, remember it is over 15 years old too. The rest of my engine was immaculate when it let go, except for what happened to 1 piston... When it was pulled apart everything else was fine

shood i

find a standard rb26 motor and replace it ~$3000

full rebuild ~$7000/8000+

rb30 bottom end conversion same as above but a bit more at a guess...

standard rb26 3k + 1-2k remove and refit

rebuild 26 5k R&R + machine work/light headwork + parts 4k depending how far

30 bottom end conversion a 2k more then the rb26 in parts

Seriously guys, I don't know where the misconception on the cost of building a 30 came from but it is only a few hundred dollars difference in building a forged 20/25/26.. the difference being in buying a $100 RB30E, tapping new tensioner locations and getting a different timing belt.

Pistons, rods, headwork, cams (unless you want to go solids), oil pumps etc are all in the same ballpark for any RB engine.

i rebuilt my own rb25det and it cost something like $2000 and took less than 2 weeks. If all you have is a busted up piston and a worn out set of bearings you can do the same. Forgies are cheaper than they have ever been (and unless your the 700hp man it wont matter which ones you use) rods are usually fine bearings are less than 150 dollars then its just new gaskets and head and main bolts etc etc. Go give it a try its not rocket science all the info you need is on these forums and a rb26 with forged pistons will be happy to well over 450 hp! ppl go over board with their builds in my opinion

head - dont touch it just pull it off check it out and put it to one side and stick it back on when your finished

bottom end - pull it apart inspect it take it to engine machinist if your not sure. Get yourself some pistons, get machinist to match pistons to bores and put pistons on rings and pistons on your old rods. Then go home and stick it together bottom ends are pretty simple follow the instructions and you cant go wrong if something looks hammered get it checked out and replace it if its oil pump and water pump you should probably replace them anyway not too expensive put that tomei oil reducer in the block and there goes the mian reasons rb26's give up the ghost. Anyway this is my 2 cents and it depends how hands on you are perhaps read up about it first if it sounds do-able then give it a go.

well awd adaptor plate is $900 + labour

+ retap block for rb26 arp headstuds another $500 + labour

+ timing belt/tensioner kit $300 + labour

+ crank collar $150 + labour

(going by pro engines pricing)

and any other nitty gritty things that you may need to fit a rb30 bottom end into a GTR

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
