looking good, I guess people have already well and truly worn out the joke of a KFC sponsor being ironic? can you post a picture of it without the skin?

in the blacktop manual? http://www.ae86drivingclub.com.au/forums/showthread.php/16050-AE86DC-Technical-Documents

go on the new zealand trademe site and look up 4age to ke mounts on there, problem solved

Actually I am driving all 3 wheels, with 19 x 2.5" trials tyres all round. I am attempting to make an off-road monster. I won't have a diff but I don't for-see any problems either because I am going to be using free-wheeling axles combined with an over-drive for the front wheels compared to the rear so they without slip will not provide torque at all.

front wheel drive has more drag and yes it has lots of issues, trust me I know. This is the last part I machined up to power the front wheels of my trike: As for this challenge I need to stop making excuses and make an effert to go. I might just drive down one of the two days and go home again at the end.

yes that will work

thanks Sloth, sales are slow though

yes easy http://s-86.com/s-20vrwd.html a few searches will help you a lot

for a basic engine build I would see no point in going for anything more than stainless valves

so possibly the bext few weeks then, sounds good to me.

so whens the intake going to get welded?

with ACL some pistons are from Mahle and some from Ross, depends on the model

ah yes, I stuffed up on one number the 4age is indeed 1.58 not 1.54 also I found out that the 2az engine at 6500rpm has the same average piston speed as a 4age engine at 8600 from memory

have been told the 2az rod length is 149.5mm which gives a rod to stroke ratio of 1.56:1 which isn't bad apparently, for reference the 4age has a 1.58:1 ratio

I agree- 496 to 514 is only 18 grams or 4% heavier. I only looked breifly but the scion guys seem to like them, the linked article had a guy reporting to use them for some serious turbo power.

There's also the K1 rods: http://www.campbellenterprises.com/toyota-performance-parts/toyota-rods-k1-toyota-connecting-rods.php 514g at only $370 a set

well I don't know about that, again refering to the 20v rods the blacktop rods look tiny compared to the black but are only 20g lighter but the spool rods look really chucky and are 20g lighter again

thanks GJM85 496 grams is quite a good weight considering a thin as 20v blacktop rod is 485g and 505g for silver. Anyone find the weight of a stock rod? Or how about the weight of an aftermarket piston Vs a stock one? and your right irokin, boosted engines need compressive strength - H beams but atmo engines with high revs can use the reduced weight of I beams because it's only tension loading.

doing a bit of reading I read in some repair manual and it says the engine uses very liners that can't be bored however the pistons are +0.5mm, I don't see any notes about needing linders to be fitted

mazda Z series? I need to look up that one Now matt in your research have you ever found anyone to have done as much mods to this engine as what you have lined up? are you the first to push this engine without boost?

Good to hear but apart from the machining I just delegated this job

we know Matt we are just talking about theoretical design, it makes no practical difference to either of us at all. So hows the manifold fab going?

yes I see what you mean, my final thoughts is in this case your totaly right- it's weaker. If however they used what they already had and it a single structure then it would of been ideal.

looks like the 2az doesn't use this, looking closer the crank is level but it just seems to have normal 2 bolt caps, which in this case would make much weaker than a burried set of caps, a waste.
