Iv blown the bottom end in my r32 GTR and don't no witch way to go about it, I'm sorta on a tight budget due to jus buying a house, if I should go with a rb30/26 bottom end or just buy a new motor iv had the car for a while but jus sits in the garage 2nd drive I went for 8months after buying the car bang bottom end gone. :(

Havnt had a chance to dyno it or nothing.

Following mods are

Intank walbro 500hp fuel pump

850cc injectors pretty sure

Full 3/half inch exhaust wid aftermarket dumps

-5 turbos

Any one know ruffley what power it would push wid a stock motor and the following mods including a ecu plus a good tune.

& if I was to go rb30 bottom end forged, what adjustments ect I would have to do.

Thanks post-133383-13942935135466_thumb.jpgpost-133383-13942935281152_thumb.jpgpost-133383-13942935621347_thumb.jpg

If your tight, stay 26 bottom end.

Its not exactly simple to fit a 30 in a r32 shell, block sits higher and bonnet closing issues where the turbo badge is on the pipe.

By the time you factor in the adapter plate, welding the rear sump bolt holes, redrilling them, new pickup pipe, some small mods to the block like your knock sensors bolt holes and clearancing for the adapter plate, piping or joiners to reach a bit higher and the fact that its not legal, stay with the 26.

If you spun a bearing, just get another crank with the long nose, some rods and pistons and your done, or just get a second hand working engine from a 33/34 (long nose crank drive) and just keep driving, your old engine being sold should cover the engine swap costs if your paying someone to do it for you.

      Stock rb25det neo questions

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
