The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

Finally got some numbers but its not done yet,

On the New motor, with the 6262 .84 TS BB CEA.

Run-in tune (super safe) verylow/negative timing, 9-10 psi. 210-220 rwkw.

Turbo is super responsive and perky even with the timing so low, I noticed instantly its very throttle responsive, its very possible my intake setup helps in this regard. But the way it moves the air so quickly I have a good feeling this setup will be pretty decent on the 30/25 with vct!

One noticable characteristic.. the turbo seems very loud. even on low boost. however i am moving from lowmount to high mount during this build, so that might be why i think that.

will be doing real tuning next week if all continues well. Will post numbers as promised when its done. Unfortunently still running hte PFC and Tomei Z32 as no one has purchased the gear yet.

results yet?

Big boy turbo, wha happened to wanting response lol

Yeah, things got a bit out of hand with the engine build and from what I have seen so far this turbo should still have good enough response yet make massive power. Its either this or the 6266. Will see how we go.

I have a 6466 on an rb28, and i expect in excess of 500awkw. Might be a little bit too extreme on a daily strees sil. Buut, look at PJ's THING, because thats what it is, a freakish THING. It has a monster and still makes powers that are usuable for speeding up the rotation of the earth arouns the axis of the suns, and stuff

I think it will be OK.

There's a 180sx 2.0 VE non VVL, with a 6466 that made 536rwk@34psi with quite reasonable response.

Then there's James NFI's S15 2.3 VE VVL, with a 6262 that made 430rwk@24psi with ballistic response (but yet to have final tune).

With my motor 2.2 VE VVL I figure the next size above from James should still provide enough response yet be able to make 450-500rwk should we choose to push it that far.

It will be either a 6266 or a 6466.

Hahaha I laughed pretty hard when I read that! Pretty deep!

Allan, the 6466 on your 26 will be fine and will comfortably make the power ;)

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
