Does anyone know if the 100kw 4age has the 7 rib block?

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.

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)

all that said I haven't heard of a 3 rib breaking so easy. Whats on your mind Hatchi?

[Hatchi]

Thanks for all your help.

I getting my 4age built and i wanted to start with the strongest base possible.
(Engine builder wanted some info)

[Sam-Q]

nothing personal but I seriously doubt your build would stress the weaker 3 rib. However the 7 rib crank and rods suit a common 20mm gudgen pin. So yeah thats what you want.

[Hatchi]

Even so... still better over builded.

[ae86]

sam knows his stuff, also alot of 4ages put through previous motorsport were 3rib and they were taking on 180hp+ and still using factory spec bottem end pieces just lightening the crank

[Sam-Q]

going to get boost Hatchi?

[Hatchi]

Yeah going to be a 4agte. Just trying to decide what rod and piston set up to use atm.

[Sam-Q]

how about just a stock 4agze? thats what everyone else does
