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

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 :worship:

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.

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

  • 4 weeks later...

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

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
