the 7age thread..

[starni_boy]

hey guys,

I did try a search, but nothing really came up. so here are my questions. I am not sure on them, thats why I would like some clarification.

1. 7afe block bolts into an ae86 crossmember with 7afe engine mounts?

2. 4age head bolts onto a 7afe block?

3. I want to run a w5* gearbox, so will the 4a to w5* bellhousing work?

yeah thats all I rememberat the moment. will post more later if I think of any.

and if there is a thread already about this, please show me because I couldnt find one.

any help is appreaciated

cheers be)

Rather than just doing *A* search, it pays to keep reading. Better info in the Tech Article section. Read some FAQ stuff on Toymods. Use google and find a good webpage rather than a forum.

1. I think the 7A-FE bock sould bolt to AE86, as I havn't heard any different. With AE86 engine mounts of course (think about that).

2. Yes the 4A-GE head bolts to a 7A block. it's been done many times before. Obviosly there are issues. The timing belt length has to be worked out, as the 7A block is taller. 2 extra ribs I think.

3. Yes a 4A belhousing will fit a 7A.

thats a 7afe isn't it?

I'm not too sure what they look like :unsure:

[ae71]

would say on build plate on fire wall

[Jonny Rochester]

That is either a 4A-FE or a 7A-FE, can't tell by just looking. And the car is either a AE101 or AE102 I guess. The 4A-FE in the AE92 looked a bit different.

[Felix]

yeah, 7age goes hard (y)

I've got one in my kesev, also wondering if a standard strut bar would fit? or would the engine be sitting to high.

I've never looked at a ke70 strut bar, interchangable with ae86 ones?

[starni_boy]

ke70 and ae86 have the same strut tops if thats what you mean.

70=86 same distance apart and everything.

[Felix]

but these motors sitabit higher than a 4age, so I'm wondering if there wuld be clearance issues

[Jonny Rochester]

The 7A block is only about 8mm taller.

[Gilly]

it will fit Felix

If it's a 1.6L, it's a 4-series. If it's 1.8L, it's a 7-series. Looking at the car (AE110 series), it's probably the 4A-FE, I don't think the 1.8L variant was introduced until the next generation series.

[Jonny Rochester]

The 1.8 7A-FE was first seen in Australia in AE92 Secas. It was sort of a AE102 engine, but since Australia was still producing AE92s (some delay due to retooling the Altona plant), they put the engine in a few AE92 Secas.

In Australia:
AE101 = 4A-FE
AE102 = 7A-FE
AE112 = 7A-FE

[RobertoX]

^^ yeah I know the cars


you can get x member spacer kits from japan that are really quite simple

drop every thing down 25mm

[starni_boy]

I got all this shit sorted now. I know what to do and stuff.

pm sent felix

[Felix]

ok, taking a gander at it now

[LordNafe]

Round tooth porsche 944 timing belt, 4AGE head, rwd water pump, and a t50 will bolt onto it.
they are 6 bolt flywheel rather than 8bolt. Will drop in on AE86 mounts and clearance isn't an issue.
I thought the block was a bit more than 8mm higher?
AE92 high comp pistons will also fit on the 7a rods no worries. Apparently the stock rods are a bit iffy above 7000rpm though.

[dr1ft-pig]

ill be building a 7age 20v in the hopefully not to distant future pretty sure I know all the parts I need I knew I needed porsche timing belt but didnt know which 1, I do now. (thanks levinafey)

now the 20v pistons will go onto 7a rods right???, is there aftermarket forged rods for theese off the shelf??? I want to rev it to around 10,000 rpm

is it going to be a non interferance motor when I'm done??? like if timing belt snaps then am I going to damage my valves???

just a few queries as I don't wanna go spending upwards of 5g working a motor to see it smash valves IF a timing belt snaps

cheers, brendan

I will post some links here for you brendan to have a look at. I found some pages on the net which were very helpful.

[LordNafe]

Ummmmmmmmmm Yeah I think the 20v pistons will go on, and yeah there are off the shelf (or easy to get anyway) ods available.

[dr1ft-pig]

cheers for the links man I'm going to read now

post it up in tech articles man, without all the chit chat in there

[AE86represent]

I am currently building a 7AGE for my AE82 hatch, I just went to a local wrecker and bought a complete AE102R rolla that has had some minor drama's ( LH front wheel is now where the pasanger seat used to be :blink: ) Got the car complete for $450.

I am also using the 4 wheel disk brake setup, and the 4x100 stud pattern hubs too. Quite a simple conversion. The engine is going to be a stock rebuilt bottom end with, arp rod bolts, and arp flywheel bolts, just so it's happy to rev to 7500 (I've heard that the stock bolts are the issue, not the rods themselves, but please correct me if I'm wrong :unsure: ). Stock bigport head, and a set of really mild street cams. The injection is getting the boot, and in it's place a set of 45DCOE webbers on a redline manifold. I'm going to wire up the stock bigport ECU so I'll still have an ignition curve as apposed to having to run static ignition timming.

Later mods will include a set of EFI hardware quad throttles and a microtech Lt10s. it's only a daily, so reliability, and not having the thing off the road for more than a day or two at a time is the key.

[starni_boy]

I'm am leaning very much towards running a 20v 7age, with a/m bottom end, just a bit more beefy for around 9000 rpm. don't really want to bore it out though or run oversized pistons.

[dr1ft-pig]

if your going to spend the money building a 7age, IMO you should buy forged rods, will handle a lot better revs

[SEXY 16]

you wanna build 1 of these engines properly you need a spare 20k

[driftism]

IMO you should buy forged rods, will handle a lot better revs[/b]

aren't most rods forged anyway??

[Felix]

you wanna build 1 of these engines properly you need a spare 20k[/b]


how much did you spend on yours? what mods do you have with it? how much power is it pushing?


sorry for all the questions...

mines all fairly standard from what I've found about it

[SEXY 16]

18k ans still no computer

I have every mod you can do and have spent a lot of money in correct places

power will be 220 bhp @ engine easy
