When balancing the crank, my machine shop drilled holes in the the counter weight rather than grinding off material as Twoogle has done. Is one way better than the other?

Gav our balancer has done both grinding and drilling. Tiny little drill marks were on most of the counterweights as well as the large ones from the factory. Grinding is generally done when material near the big end journal needs removing and drilling is done when removal of material from the counterweight has to go.

Hey Paul how do u rate the cp ring sets? i pulled my motor down after the initial dyno tune to check pistons etc and noticed a couple of the ring gaps had lined up with each other, any ideas why? i've not had any issues since reassembly but not something i want to happen if possible. I used to run Jun cosworth pistons and never had any issues, but since my bore is bigger than 87mm i cant use the jun ones anymore :D

coming along nicely.

wats your opinions on the spool rods paul?

Spool rods are manufactured by SCAT in america. SCAT have quite a good reputation as a reasonable quality product and are good value for money. In my opinion they are on par with Eagle and other rods in that price range.

Hi Paul - Just to clarify. Spool rods arent made by Scat or by the company that makes Scat rods or Eagle rods.

Not being picky - I just want that clarification made.

i think you need to clarify where they are made then...why do they use SCAT branded rod bolts??

I was more than happy to think they were made by SCAT as they have been making quality rods in USA for over 45 years and have an excellent reputation.

On your website you even use the same spiel as SCAT on your website "High tensile 4340 forged steel" "doweled cap for precision alignment" etc

When I bring the rods in they do not come with bolts. So I have to source the bolts here in Aus. I was buying bolts from Rocket for a while but they kept running out of the std ARP bolts and would supply me with the ARP 2000 bolts with SCAT on them - like you have there.

I now buy my bolts from Quantum here in Bris as they get them in from the US for me in quantity.

You can talk to Ryan at Rocket or Jason at Quantum to confirm.

All my rods now have ARP 2000 bolts with no SCAT on them.

Cheers

Scat are made in China, it is common knowledge now.

The price alone reflects where they are made.

Whether Spool or Scat are made in Taiwan , China , India , USA or Aus etc is really irrelevant. As the steel in SPOOL rods is 4340 ( had it tested several times ) the tolerances are perfect, the rod bolts are ARP and the quality is exceptional.

There are plenty of cars making power with SPOOL rods ( and the like ) and there are numerous workshops who recommend them ( talk to Mercury Motorsport, Proengines, Harris Engines, 6Boost etc ). Fitzpatrick Speedworks has a RB25 making 460 rwkw with those same SPOOL RB25 rods you have.

Scat are made in China, it is common knowledge now.

The price alone reflects where they are made.

Ill email Scat in the US with a link to this thread. They can confirm or deny what you claim.

No doubt about the quality of the product you are selling as even the trained eye cannot pick the difference between the Spool and the Scat product. They were perfectly balanced and tolerances were exact when checked.

Thanks Paul, Im happy you like them.

I will post up some pics soon of the differences between SPOOL rods and Scat rods.

Cheers

cool...are you by any chance doing stroker cranks for anything other than RB30?

you will probably find that these rods are the same as electronics, the cheap and nasty stuff and the top of the range high quality stuff is quite possibly made by the same ppl, but some items are built to a price and others are built to a quality.

    • Well it does have a motor with the same DNA as an Accord V6 motor. The J30A is a successor to the Tiger rice cooker C32A motor found in those cars.
    • FD RX7 I would probably marry if legal R32 GTR is toughest NSX looks like it's made from leftover Prelude and Accord bits  
    • When going to a suspension shop should I send them the default nissan settings or just let them do their own thing? I ask this because I have aftermarket rear camber arms and my car is lowered a bit (front end is basically stock after I change to those nismo bushes)
    • Ok sounds good, thanks for your help. Hopefully if I end up changing it to the nismo bushes I don't get that veering issue. I don't think there's a point in lubing up these bushes again. Weird that it it makes just as much noise with all the grease inside it versus without grease prior to removal. Bizarre.
    • Yeah, you don't need camber bushes on stock arms to make a car drive straight unless it's got another problem. F'rigsample, slide the thing into a kerb, bend the front subframe mounts a little....subframe is now twisted, shifted or otherwise in the wrong spot...and you need to do funky stuff with the wheel alignment to get it to drive straight. Maybe a little more caster on one side, or a little more camber. FWIW, I can have my camber off side to side by a half a degree or more, and either way, so more one side, or more on the other, and the car doesn't really want to pull to one side. It will definitely ride road camber differently, and want to track uphill (ie, towards the centreline when on the LHS of a normal crowned piece of road, like it should) or want to roll downhill (which it really shouldn't). But on fairly flat road surfaces, like the middle of a 3 or 4 lane motorway, a half a degree either way doesn't make a lot of difference. I sometimes do quite a few miles with my wheel alignment messed up, because I don't always get a chance to set it right again after a serious dismantling, before I have to drive it to work again. Like, a whole week's worth of daily shuffle.
