black top "I THINK"
Just wondering I heard all the talk about a stronger block?
Which 4age 16v engine comes with the stronger block?
I have a 100kw 4age 16v out of a ae93
black top "I THINK"
Does anyone know if the 100kw 4age has the 7 rib block?
and if u want a blacktop bottom end im selling one
To the best of my knowledge, bigports have a 3 rib block, anything after has a 7 rib. I think all 4AGZEs have a 7 rib. And I think there's a late model bigport with a 7 rib.
to answer your question, a 16v 4age 100kw smallport does have 7 ribs.
Ok heroes, as far as blocks go, it goes like this:
3 Rib block - Smaller bearings, used in 4AC, Early 4AGE Bigport
7 Rib block - Larger bearings, Oil Squirters (although SOME may not have this, i think late bigport). All smallports are 7 rib, as well as late bigports (JDM AE92) 20V Block is also 7 rib with oil squirters but has some minor differences.
You can have any brew you want... as long as it's a Datsun / Corolla / What is that?
AE86 4age bigport - 3rib
AE82 4age bigport(bluetop) - 3rib
AW11 4age bigport(bluetop) - 3rib
AE82 4age bigport(red/blacktop) - 3/7rib>> no squirters (very rare for 7rib but do exist)
AW11 4age bigport(red/blacktop) - 3/7rib>> no squirters
AE92 4age bigport(red/blacktop) - 7rib>> no squirters
AW11 4agze bigport - 7rib>> no squirters
AE92 4agze bigport - 7rib>> no squirters
AE92/3 4age smallport (redtop)- 7rib>> with squirters
AE92 4agze smallport - 7rib with squirters
AE101 4age 20v (silvertop) - 7rib with squirters
AE101 4agze smallport - 7rib with squirters and different block cast and hence different knock sensor used
AE111 4age 20v (blacktop) - 7rib with squirters
**To find 7rib blocks look for motors built post march 88** Not saying that every motor made past that date was 7rib, but epc p/n change over occurs at that date.
(there are a couple of others, not listed for availability purposes)
