http://www.rhdjapan.com/tomei-genesis-comp...3g-rb284g-55011 i dont need to say anymore, have 3 mates all running 1x 32 & 2x R33 gtr's most have spent 15k plus and are no where near that figure if you dont go tomei.... heres another option thats.. oh wait.. well over £10k bottom end £7.6k - rb30 from thor - this is only rated to 700bhp if you want bottom end rated to the 900 figure you where chatting about its £8.8k and oh wait thats without a head... oh or cams oh or a turbo.. oh yeh without fueling, oh wait and without an ic, suspention, brakes.. uprated prop, rear diff, hg, oh and dont forget youll have to spend about £2k on a clutch to handle it all and not only that oem transmission on a gtr would not be able to cope with 900bhp but just to sum it all up..... oem transmission will NOT handle '900bhp or more' so here's what you need.. http://www.rhdjapan.com/os-giken-6-speed-s...-rb26dett-50745 ohhhh and guess what... that box alone is more than the £10k you budget for the WHOLE BUILD think i have made my point very clear.. 'fuck knuckle' Oh p.s - please post on gtroc about... for example... I have 10k and im going to be able to build a '900bhp maybe more' gtr and i will very much enjoy watching them rip you to shreads.
