Building a 7age.

[pen15]

if this helps people i have pics of sump clearances and other 7a related things

sump to sway bar


sump to crossmember


hope this helps anyone with knowing where the sump sits on a 7age setup

re. the headgasket, the 7afe gasket is .6mm and metal but the hole passage for the oil/water are smaller/different design.
can enlarge the passages but might/will damage or warp the gasket.


(old 7afe vs new 4age headgasket)

[jimmy19650]

From what I have read, depending on head gasket used

Small port pistons = roughly 11.5:1 CR
standard 7a pistons will result in less than 9:1 CR
Late ZE pistons just over 9.5:1 CR

Has anyone used the 4agelc pistons which are 9.4:1 CR normally in a 4ag motor. I would image they would result in about a 10.5:1 CR

dont forget the compression ratio also depends on if the builder chooses to deck the block down to the piston or not...

[jimmy19650]

Yes I understand that, but with all things being equal, it would be interesting to see what compression ratio that piston gave compared to all the rest.

Wondering if anyone has used blacktop 20v pistons and a blacktop 20v head in a 7age?

[70XIN]

my setup does

[dehney]

what power is your 20v 7ag making ?

what rods are people using so you can make the 7ag rev a BIT higher ?

[s13 james]

i will be using spool rods

[Delazy]

most people are using spool or 7oxins rods

although robbo did use standard 7afe with ARP bolts...
