R32 Gtr Offically Dead- Rebuild Time

[den001]

my gtr has lost compression and is driving like a one legged camel....

i have plans for it to make around the 330AWKW...

so far i have gotten myself some wiesco forgies 87mm....

will i need rods for this power figure???

i have dash -7 turbos and fuel system and management

i was thinking these parts

acl race bearings

crank collar

oil restrictor

good pump

oil return from back of head

fresh head (reconditioned) stock cams with cam gears

metal head gasket

aftermarket rods

forged pistons

anymore suggestions ???

Rods - stock is fine

Just a set of pistons... get the crank checked also. If its far gone just get a R33 GTR crank and not worry about collars etc.

You'll only tell that once you get it looked at.

Otherwise good list of parts.

Dont really need oil return from the back of the head if the restrictors are done right, i dont have a drain

sweet as i was thinking a tomei sump baffle , what do u recon?

also i read somewhere on the forum that its better to use Nissan piston rings in the Rb blocks due to the beading in process... should i use these or use the ones hat come with the wiescos???

also head studs???

main studs???

Dont really need it IMO. Some will say you do, ive seen club day circuit GTR's with your power run for a few years without.

So unless your out there ALL the time, 10 times a year or so, probably not needed. Certainly not for a streeter.

Not 100% on the rings, i couldnt imagine a RB block being different in terms of getting the ring setting.

valve guides...

[den001]

ok, i have changed my ways abit, i have sold off the dash 7's and the managment today,also my rb30/26 pistons and rods, i have also sold my gt80 and now have a to4z

im going to use the parts off my other car onto this....

sofar i have

hks 272 10.2mm lift cams

hks springs to suit

bronze valve guides

1mm oversized ferrera valves

hypertune plenum

85mm tb

jun pump

custom sump

bare virgin block

virgin r33 crank

motec m8

obviously this will make a shitload more power than the quoted 330awkw, ive had a look at some of the dyno figures in the fi section, ive been to afew shops today and asked about a piston and rod combo for a RELIABLE 450awkw... everyone has different outlooks on different brands, one guy says this, the other says that....

i have come up with a combo which ive been told that will work very well, je pistons or mahle pistons and a set of manley turbo tuff rods???

will this be adequate for a reliable 450kw, or is it overkill???

any more combos yous know of with firsh hand experience???

cheers

JE pistons and a set of jap rods

RPM is what kills rods, all depends how hard u wanna rev it?

been told that JE will hold 600-700hp

havent heard of many people using mahles

[SimonR32]

argo rods and arias pistons here...

430rwkw and ever reliable

[dave32gtr]

Hey what is your budget? I like JE or cosworth pistons, and maybe JUN or Tomie rods?

[den001]

i sold the gtr and am now concentrating on my rb s15, a build should cost u about 7000 to 9000 depending on where u go, the build i have atm is costing about 16,000 bvut is full house everything, in my 26, i also have a 30 which i will bolt my big turbo on and put a auto in later, the 26 will have a to4z and a 25 box, want to run consistent 9 second passes with this setup, the 30 even quicker
