u can use s13 at the back or upgrade to r32 skyline brakes all over the hub will fit good in the hilux diff since 5 stud nissan and 5 stud hilux have the same stud spacing.

hilux diff i would go for a 4.1: 1 or 3.9:1 u can find its code at this forum.
hilux diff

as for the master cylinder u can use the 15/16 sold by datsport.com it will be perfect and u will have a good breaking machine.
any other information u want just request it. same work is being done on mine

Yeah am leaning towards the sr20det, mainly because i have the cross member and everything is mounted to suit the engine.
The hilux diff idea sounds good, what model hilux should I be aiming for?
As for the brakes it currently has 200b front struts with s13 calipers with drilled slotted rotors, running r31 brakes on the rear. Am getting adjustable coilovers with adjustable camber tops with the new coupe, these are an r31 strut shortened to suit the 1200 with the r31 brake set up. So will work out what I'm putting on the coupe, probably the 200b struts, keeping the coilovers for the ute. As for the rear brakes, not really sure what to do there.

having a ute i'd rather go fot a hilux diff. same ratio as r31. more reliable and already with leafsrings. hilux diff can be upgraded by an airlocking difflock. as for the engine why don't you buy an sr20det and change pistons to ur de. gett a t28 turbo and try that way if u wanna be streetable. not streetlegal. and what about the breaks. have u already got an idea about that??

or get a hayabusa v8 from america thats if you have a spare $40,000

I'd love to see some one put a turbo Busa motor in one hookin up the drive train could be a lot of work, tho they have done it in smart cars. 300+ hp with a 6 speed sequential box = lots of fun

By "drag" i mean anything driveable, not necessarily street legal.... Will have the coupe as a daily so the ute will be purely for fun. Considering it aleady has the sr set up was thinkin turbo all the way.. But have a mate who builds rotary engines in his spare time so that got me thinkin about droppin a 13b turbo into it. The tunnel is extra large in the ute so will have no trouble fitting any type of gearbox in there...

In saying 'DRAG', Do you want mean you want to register it?
If not, Like Laney said, an RB engine would be sensational... (especially a RB30det!!!) long engine though.

Or go for something different...

GEN 3??? - Aluminium, light weight - then stick 8 to 10 PSI up it's arse!
You'll be holding on for dear life no matter what sort of rear end set up you run!

slowly but got sick of waiting for mates to weld #### so brought me own mig and tought myself ay best thing i could have ever done. . so yeh im just plotting away at it alot more welding and bracing to make it as safe as can be lol

That can't be legal.... But it'll be awesome either way. I'd love to see that up and running, obviously a few years away?
How's the ute coming along anyway?
