im about to start a high hp 30 motor. i know most of the things require but have i missed any out and what weakness are there at 700-800hp.. i dont want to do anythin thats not realy vital but any suggestiong would be great

30e block..30e crank will need big end grinding..

carrillo rods,, wisco pistions (good coice?)

std gtr oil pump ?ok?

knife endged and balanced crank (inc flywheel & power enterprice pully)

and thats pretty much what def will be getting done..

will be for dyno runs only at high power.. and maybe drag at lower power levels,

things im not sure about are (to save on build costs)

o ring block? or any extra block strengthing.

trust oilers on main bearing trust?

head studs? main studs? vs std gtr ones.

any heat treating/coatings?

26 mains and grinding channel in 30e block?

oil squirter fitting?

or any think else i have missed?

i dont want to do anythin thats not realy vital but any suggestiong would be great. ps that 30 post is far to big and its full of crap most and cant sniff out important info..

For a 'reliable' 700-800hp, everything will need to be modified or changed, particularly the valve train and head porting (you are using the SOHC 12V head, yeah?)

carrillo rods,, wisco pistions (good coice?)

std gtr oil pump ?ok?No, at least an N! pump with crank collar

knife endged and balanced crank (inc flywheel & power enterprice pully) I also got the crank cryogenically treated

and thats pretty much what def will be getting done..

will be for dyno runs only at high power.. and maybe drag at lower power levels,

things im not sure about are (to save on build costs)

o ring block? or any extra block strengthing.Not needed

trust oilers on main bearing trust????

head studs? main studs? vs std gtr ones. Yep, ARP do these, retap block to take Rb26 head studs

any heat treating/coatings?Recommend getting pistons coated

26 mains and grinding channel in 30e block?????

oil squirter fitting?Good idea, but aparently very difficult to do(about to find out)

or any think else i have missed?

GDZ1LA - Please read the RB30 sticky and also search.

There is more than enough info on what your asking about this forum.

People cant be expected to answer/repeat themselves time and time again.

If you do truly want to build a 700-800hp motor, then taking the time to read a detailed thread should be the least of your issues.

Rushing into a build is what will be the sad end to it.

Thanks

      M35 Stagea intake suction pipe

      Not easy to find pics from 15 years ago, but here is a partial one. Keep in mind that it curved immediately from the airbox, then kept a straight line for the MAF to read correctly, followed by a 45 degree bend straight down to the turbo. This connection was the most difficult as it had to twist as well as bend to meet the almost vertical straight section of the intake.

      Yes, well, wrt a wheel alignment, there are two types. Either: You have very little added adjustables, in which case the alignment can be done by anyone in any tyre shop or equivalent, and will only take 30 minutes, and so there is no reason to even consider leaving the car there. OR: The alignment is a major exercise because you have adjustables everywhere and so you will need to be taking it to a shop that is skilled and experienced at setting up race cars and the like, and you won't need to worry about leaving the car there.

      R35 GTR servo and master cylinder conversion

      By burn4005 · Posted

      does anyone know the specs of the R35 master cylinder, rear ratio and knee point? the BM57 is a 0.4 rear ratio with a 435psi knee. I'm looking for someone with a much lower knee pressure. the piston area of the R35 brakes isnt that big so might not work for me but this is interesting.. the other option for me is a GU patrol master cylinder and booster and do the prop valve externally.

      It sounds like by avoiding maintenance you may be doing more damage than a hypothetical guy in a workshop taking it for a spin. Not sure if you are just being paranoid or things are actually that bad in the US. Find a reputable shop not run by dickheads. Look for people that take pride in their work. Stick around for the day if you have to
