Rb25Det Bottom End Rebuild

[skyline32sup]

Ive never had to get a rebuild done before, just wondering would it be better off getting aftermarket bearings, pistons, etc or just a stock 25 bottom end, or maybe just bearings? I'm getting prices tomorrow, but just after what would be the better option.

Ive got a full reco head, and will be running 400+hp on e85.

any info/imput would be appreciated, thanks!

Rather depends on why you are rebuilding it. What was the reason you pulled it down? Have you inspected the pistons. bores and bearings?

If your going to be pushing it, go some ACL race bearings, forged rods and pistons to avoid the heartache and empty pocket down the road, spend a little now once instead of spending twice.

300Kw is about at the relabiltiy limit of the game, you could get away without it but its all in the tune and how you treat it.

Plenty of people running more from them with stock bottom ends, plenty also having them fail too......id be leaning towards forging it to make it survive and leave room for other power upgrades, once you have 300Kw you will be sick of it and chasing more, its only human, build some room for safety.

Havent pulled it apart yet, its still sitting there. Has scored pistons, and piston walls have wear. Not to mention i bought a reco head cause cams had groves and marks on them, and the front of the block didn't seem to have much oil, due to when i bought it serviced it and had about 500ml of oil.

i figure since ive gone all out, i might aswell have a decent bottom end, id hate for it to go pop on the dyno.

300kw is enough for me, its a street/track car, anymore, not after massive figures
