Re-building ya 16v? Amo as like my self? Here's some part numbers for 4A internals

This is all web based stuff As I wanted to get part number to give to my mate at toy for my own build so if there's any differences or suggestions please feel free to add so I don't get the wrong stuff
Couple notes down the bottom to

This has been pulled from forums and cut down so ignore any double ups

4AGE and 4AGZE rod's

"Forged" pistons at bottom
I say forged with " as there seems to be dispute about this although baza at MRP says his OEM +0.5's on trade are so I'll take his word for it

notice how none of the Silver Top connecting rods part #s coincide with any GZE con rod part #s.

notice also how there are only 2 gens of the GZE (as i thought) the AW11 version and the AE92 version...and the con rods of both share the same part #s.

also, notice no matter how beefy they come, none of them is listed as "forged".
it does say however, that some of the AE92 high comp motors came with the same rods as the GZE....while some came with the same rods as the silver top. nowhere does it say though that the silver top and the GZE rods share the same part#

Corection they do use the same rod's, if you look at both of them they are the same so do you not believe your eye's?
Ok then if you don't here is more proof

AE92 4A-GE & 4A-GZE connecting rod: 13201-19095 from 05/87 to 02/91

AE101 4A-GE & 4A-GZE connecting rod: 13201-19155 05/95 to (no date stated)

The connecting rod story is not so simple. There have been at least seven 4A-G connecting rods.
The first, 13201-19065 was used in all 4A-GE from 06/84 to 09/87.
Somewhere along the line, 13201-19065 was made as a substitute, only for the 4A-GE.
The third, 13201-19095 was used in the 4A-GZE from 08/86 to 09/87 and in the 4A-GE from 09/87 to 12/89.
The fourth, 13201-19096 was developed as a substitute from 09/87.
The fifth, 13201-19125 was used in both the 4A-GZE and 4A-GE from 02/91 to 10/91.
The sixth, 13201-19126 was used in both the 4A-GZE and 4A-GE from 10/91 to 05/95.
The seventh, 13201-19155 was used from 05/95 onwards in the 4A-GE (20).

AE111 4A-GE connecting rod: 13201-19155 05/95 onward

Also terms of crank, only two where made, 40mm and 42mm, no difference between models V

The first, 13401-16010 was used from 06/84 to 09/87.
The second, 13401-16020 was used from 09/87 in every 4A-GE, 4A-GZE and 4A-GE-20 that was built.

Something's some people that seem onto it have added..

"Also it was not me that said the ae101 have forged rod's it was in the tech reference at club4ag, if you want to dispute that go talk to them."
(Although I doubt this from what I've read)

"Get them shot peened and cryoed for safety."

"..also on a side note, titanium rods suck so if anyone dreams of titanium rods....they dont last, they dont handle stress cycling very well, in other words they are for use for a limited time only, then they fail, so stick to forged and billet."

"The crank is forged." (Dunno but the 42's seem to hold up fine)

"Change the rod bolts to ARP rod bolts because that is the weak link."
(I can vouch for this as all the stuffed 4A's me or others I've spoke to have pulled apart, they have come lose or snapped (probs DIY builders) so follow next note with ARP jobys)

"Most people torque rods down to a certain spec which isnt the correct way to do it, you assemble them out of the engine, measure bolt stretch and at what torque they were at, and then when assembling, torque them to that spec."

Last note makes good sense to me

Pistons for builds
These are the 10:1 NA and 8.9:1 ZE

Just for random info from my brake upgrade to save people looking around

-brake pads from a 90's subaru impreza work with the ST185 twin-pot calipers. not sure on part numbers but EBC part number is DP2819. The bottom of one pad per caliper needs to be ground off a bit, but 1 min with an angle grinder does the trick
-Front calipers fit the rear with a 6mm spacer and using front brake discs. My wheels are still hubcentric as about 3-4mm of the hub still sticks out but other wheels might not be, better solutions are out these but this works and no re-drilling rotors each time they need replacing.
-longer wheel studs are needed, ARP part 100-7715. Note: this part # is for 1x pack of 5 studs. These are quite long so might not suit some applications, Nice do wheel studs too.
