Hey guys just wanted to know who has used ARP bolts for their engine build? ARP dont make a set for a 3SGE beams and I wanted to know if the bolts are the same between the generations?

Same goes with ACL bearings. Are these all the same as well?

Rod bolts are the same through all out all 3SGE/3SGTE models.

Other useful info:
ARP Main stud kit:
203-5404

ARP Head stud kit:
203-4204

Have got the ARP stud kits in stock too just not the rod bolts :(

have used ARP mains before with no issues, but have also had a situation where they distort the bearing when torqued up to their spec. Bearing clearance is as per manual when using stock torque settings and main bolts

use ARP with caution.

are the acl race bearings graded like toyota ones for perfect clearances?????

ACLs STD are rated against Toyota OEMs as:
Big ends - Mark-3
Mains - Mark-5

When I last threw a set in the clearances all were within Toyota specifications and within the specified clearances.

As an idea, the conrod bearings from Mark-1 to Mark-3 differ by (for a 2JZ engine)
Mark ”1” 55.025 – 55.031 mm
Mark ”2” 55.031 – 55.037 mm
Mark ”3” 55.037 – 55.043 mm

So I need to torque bolts to stock settings not what arp recommends to save my bearings?

I think you should do what you believe to be necessary based upon your situation and the demands of your setup.

Was more a friendly note to you about something to keep an eye out for when assembling your motor as i have seen it happen before when using ARP main studs as opposed to stock ones.

Cheers thanks for the info :) Ill be doing a build thread once my car is immaculate (as in all faults fixed, its been a long road!!! Dam second hand cars) All I have left is the brakes and bushes. Should all be in next weekend.

Then its time to find an engine suitable enough to recondition. Might get lucky in Japan since its a complete bottom end strip down and ill be using my head. Running out of money haha

ARP bolts have thier own reccomended torque settings , that are based on the correct use of the ARP lubricant. At the same torque settings, APR bolts can exert much more clamping pressure than standard provided that are installed correctly.

They are a great product, my engine is full of the stuff.

Torque each bearing cap, with bearing installed, to the desired torque, and measure the internal radius with an internal micrometer. Comapare this radius with the measured radius of the crank journal. Use your engine building experience or a reliable reference to determine if the clearances are sufficient considering the lubricant you want to use.

I didnt match bearings to my crank (as is possible), but had the crank reconditioned to a certain journal size and bought 1 size of bearings to suit the nominated journal size. Even then we assembled and measured each bearing and then matched them to the 'identically machined' journals to get the most consistent clearances.

^^^ this is only relevant because of the increased clamping pressure exerted by good aftermarket fasteners. Extra clamping pressures make for difference clearances from stock.

Thanks Matt. Only ever used ARP bolts (sometimes custom) for any application I could like manifolds, flywheels, bell housings and engine builds. I consider them a requirement for any engine build as it is great insurance and worth every cent.

I understand that there are many factors that need to be considered when applying torque to bolts from my AME days but I have never done an engine block before. Might just leave this one up to the experts at the machine shop since they are machining my block already, might as well get them to do the assembly while they are there. Really want to have a go though as this is the final frontier in automotive mechanics for me.
