Hi.

Just got my vg30 rod bolts from ARP for my RB25DET s1... But looks alot like the Nut will run out of thread when put together in the rod?

Do I need to ad a shim or?

Thanks for any help.

The VG30 ones fit the RB26 rods, For the RB25 you can use SR20 bolts.

Yes, but i have the VG30 bolts.

Arp make connecting rod bolt washers.. Can i use those to compensate?

I can make my own hardened washers, but need to know what HRC they are..

Also do rods need to be resized after a bolt change? What if i dont do this? Because engine is assempled.. and would hate to tear it apart now, and need to buy a different size bearing now. :-(

Put the VG30 bolts on the shelf or ebay and buy the ones that fit. Rod bolts aren't something to take a risk with. you do need to resize the rods once you fit bolts, you can't fit them while the rod is in the engine, it takes quite a bit of force to remove the old bolt and you only need a tiny bit of misalignment to put the tunnel out of shape. You'd be better off leaving the standard bolts in there rather than stuf around fitting the wrong ones. Might be a better option to buy a set of used 26 rods which the bolts will fit and are a heap stronger than the 25 ones.

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
