the pin diameter for ae92 is 20mm.
the ae92 has the 20mm bigger pin size, the 18mm was from the ae86/ae82 4age .
the 81mm is std bore size.
those toda parts listed will be fine
but you may want to get the shim under kit with it, that lift might be dangerous with shim over design.
rods? use oem if you must but tomei make some nice items.
there may be a nicer non-jap equivalent but your best to ask someone who builds using them. try yager or bob holden if you can get a hold of him (hes still from around your area i think)

Evan,
The 100Kw 4AG has 20mm gudgeons so the Toda pistons will be ok. I am running 11.3:1 CR with 304 degree 9mm lift cams with standard rods, no problems so unless you have plans to rev past 9K I would say just get the standard rods balanced, no need to buy after market.
My only other comment would be about the 0.8mm head gasket. With the 11:1 pistons and this gasket you would be getting close to 12:1 which is getting very high for not much (maybe 4hp) gain. I would use a standard head gasket !

you could just use std rods but balance and shot-peen them for durability
if i was building an all out engine id buy some ncie light aftermarket ones, peace of mind i think

Evan,
Just read AE86Drift comment about shim under buckets, I disagree. As I said before I'm running 9mm 304 cams and using standard shim on top buckets. This engine is used for sprint racering and is constantly revd to 8.2K and I have never had a single problem. Also I know several other people using same or similar cams with shim on top and none have experienced any shim spits.
Your call but from my experience the only thing you will achieve is to make the supplier of Shim Under Buckets richer !
|
ah fair enough then. if you keep it 9mm lift i spose ull be OK then eh?
i stand corrected evan.
does anyone know the maximum before having issues with the bucket design?

Cams up around the 310° mark, with 0.360"/9.1mm lift are needed. You'll also have to start thinking about getting some 'shim under' buckets, which have the valve clearance adjusting shims as a small 13mm pellet shim, rather than the 25mm dia shim that sits on top of the cam buckets. This is because with cams bigger than the low 300's and roughly 8mm lift, the 'shim over' buckets will occasionally catch the edge of the shim with the top of the lobe of the cam and spit it out the side, thus RAPIDLY destroying the bucket and most likely a fair chunk of head in the next few milliseconds. The shim under kits can be obtained from TRD at hideous expense, or from other racing shops for (merely!) large amounts of money.

maybe ull be safe evan with the cams you've chosen

not from toda
but you dont want it that high, you're going to run into more expensive fuel the higher you go up in comp
what you have stated sounds great for a hot 16v man dont over do it for a streetcar/club day racer

Hmm
also forgot to say i will be running 20v throttles and trumpets.
I wonder what sorta power i could get?
hopefully over 170hp
Also i am wondering what sorta computer to use.
1zzfe valve buckets should be able to be purchased through Toyota.
Can't wait to start... i have another 100kw lined up for $300
w00t

Evan,
12:1 CompRatio - as I said before, too high, the gain from 11:1 to 12:1 is about 4hp and it simply isn't worth doing !
1zzfe buckets - you still don't need them ! Run the standard shim on top bucket.
Power - I got 110rkw which if you allow 20% drive train loss works out to about 185hp at the crank. This was with 43.5mm 20V throttle bodies. With you cams I think about 175hp would be a ball park guess. The real trick is getting the right inlet manifold diameter and length. Mine is 275mm long and 40mm ID, which would be far off what you need.
ECU - I'm using a Motec M4 but if money is short get a Microtech LTS8, lots of guys I know are using them and they seem to work well.

FYI the 1zz bucketless set-up cost approx $28+gst each from toyota, so multipy by 16 =$ too much, especially considering the
evidence put forward by LeesWF.
I have been looking at getting them to save some heart-ache, but I think I might do without, specially since Im not running cams that big!
