I did mines at 70 pounds.

dfoxengr

some people say 68 and other range it out to 84 or so. safely i am doing mine 76

Whitfield Inc.

We use GSR headstuds on that combo and torque them to 70 w/arp molly

WHITFIELD-TUNED

actually why wouldn't you use the arp pt#208-4306 which are specifically designed for the non vtec block with the vtec head?

dfoxengr

because gsrs work perfectly fine. its basically the same thing. just a small length difference

WHITFIELD-TUNED

kool i would just rather use the right parts for the job but hey yes GSR's work

GOLDBERG

i did my gsr at 65 ft/lbs

myhatchrips

70 ft lbs with arp moly lube
85 ft lbs with regular 30 weight oil.

so ls arp rod bolts will not work? for a b18b1 b18c1 combo... because this is what i found at lightningmotorsports.com

lightning motor sports:

ACURA B18A/B 11MM part#208-4302
ACURA VTEC B18C1 11MM GSR part#208-4303

says they are the same length? whats the deal?

will the 208-4303 work for a b20 block and si head?

96MidoriHatch

anyone?

Dan GSR

4303

will work perfectly with B20 vtec

it goes just like this...
first torque to 18 ft-lbs
second torque to 40 ft-lbs
third torque to 50 ft-lbs
fourth torque to 60 ft-lbs
fifth torque to 74 ft-lbs.
in between each re-torque you loosen the bolt 1/4 turn.

you always torque ARP fasteners at least 5x's for a proper torque reading.

/\ Does that go for a b16a2 head and b20z2?

dfoxengr

ive never heard of 5 times.

i do 22 then 46, then whatever the setup calls for . 65-80...

RABHonda

so you do it 3 times hybrid? thats really good enough. that is the standard for all engine building, but ARP suggests re-torquing 5x's.

this goes for anything on an engine that gets torqued.

dfoxengr

cool. but ive never had a problem so ill continue that way
