ah of course I misread the question. Best bit is 4afc engines are worth peanuts

when I read the first page I was thinking: here we go another dreamer that won't ever do anything. I changed my mind when I saw the 3 rotor insignia

far out, what size are those wheels

oh right.... so a chunk of salt probably got thrown up there yeah?

rust in the inner wheel arch, I have never seen rust there before in any KE. Are you good with a welder?

well I know how to find pressure related leaks but not vacuum. Might be worth visiting a carby place/good mechanic

pretty much what I indirectly said it my last post. It is possible to split and make an adjustable intake gear for the head but its very difficult. To make adjustments then the main gear would have to be adjusted which as you said would change both and then the intake would be independantly adjusted form there, a real shocker to work with.

your right all engines would behave different , I just can't see 0.5 degrees doing much but hey I could be wrong. That link looks useful, I will have a look once I have time to thanks. So with the 4afe would the guy fit a single adjustable cam gear? if it helps a 16v model fits straight on if you swap the bottom gear as well, after that you should be able to fit the 4ag belt also. Either that or modify the stock gear. Making an independent gear for the exhaust is possible but a massive pain to do. Your right the gaskets are different. The 16V has the holes staggered to have the bulk flow from the back of the head to then let the outlet of the water to the front of the engine. The 20V is the opposite, running a 16V gasket in a 20V head will let the rear cylinders get more cooling than the front. With the cooling systems like what I use only the water in the port behind the throttles gets changed in direction, so by rights the cooling system flow in the other side of the head should not be any different in having equal flow, does that make any sort of sense?

your on your own, I don't know jack about carbs

4afe or 4afc?

you know beerhead I know that you have more practical knowledge than me but I am really scratching my head with this one. I did some proper measurements and I found that the FE gear I have happens to have a circumference of almost exactly 360mm, which means for every 0.1mm shaved off the cams get retarded 0.1degrees. So for a 0.5mm head shave you advance the cams half a degree. I said nothing in my previous post that related to me having a "she will be right" attitude. I was actually using the reference of my own experience on an engine using a cam gear that I used to alter the advance/retard and the results I got with it and other experiences of people with 20V engines. I admit what I worked on had a stock cam but I found that less than a few degrees did crap all. I admit it's not an ideal comparison but I would of thought from my experience and others that half a degree of retard it would do very little. So a bit of an educated guess maybe but not a careless expectation that it would work. I only have a basic knowledge with cam results in the real world, can you tell me how advancing a high duration cam causes the power to shift lower in the rpm, shouldn't it do the opposite? Also why don't the aftermarket cams off the shelf have the grinds offset so they automatically have them with the additional advance with the stock gears? I mean isnt that the point of buying an upgraded set? or is it in regard to making the most of what you have in terms of a compromise for overall driveablity? You probably already worked it out but the static calculated CR of the 4afe using the later head would be 14.4:1 using the smallport pistons and a 1.2mm gasket. Same goes for the 20V cooling system, I know that the de-icing chamber gets the hot water instead of the cold and it was designed to be that way. So as a result the air has to go through about 150mm of a port that might be around 40 degrees hotter. I have done my own testing with this and calculations, I have done comparasins between my engine and someone elses who has very simular mods and I ran this type of cooling system for about 4 years before I sold any conversion parts. As I understand it I am using something a cooling system design thats similar to a 16V that Toyota also spent millions on. There was no guesswork here, no assumptions and has been proven on the road and off at the racetrack by multiple people. I have busted my balls making sure everything I sell works and I have a lifetime warranty against defective work/function on my cooling parts to back it up. I think its really disrespectful you take a cheap stab at what I am doing and I thought I knew you better than that. BTW my offer still stands on refunding/swapping that early model rear bypass you ended up with simply because I think it could be better. All that said I admit sometimes I am going to screw up and get info wrong, misjudge something or make a wrong educated guess. All I ask is a polite reason why I am wrong.

I disagree, I worked out a while ago that on a 20V if you shave a whole mm off the head you only changed the cam timing 1.5 degrees or something like that. Depending on the model of 4afe they have a huge cam gear and there would be less of a difference again

you only need 2 ignition outputs and 2 ignitors if thats applicable. For non turbo applications there is no power difference.

looks mean

I don't see why not, you could probably bolt up all the block mounted brackets

I have to agree with that one

aftermarket ecu? if not I strongly suggest it

yes I spotted the silvertop, whats your location and welcome to the forum

yeah I am up for some info and pics

it will bolt in and I can't imagine the engine management having an issue. By the way I think those people you have seen are speaking crap, probably leaking a head gasket at the back of the engine.

stupid as in me wanting to hit my friend for even listening to them. My friend was chasing some ignitors because he didn't listen to me about corolla coilpacks having their own. So he goes to the Bits of Italy guy and he doesnt sell him the most unreliable external ignitors I have ever seen but the asian copy of them... right. After that he didn't even want to refund the money.

ebay? wanted add on ae86dc and here? I can only help you with some potential bits for the conversion

ha! even if there where some they all would of ran off with their tail between their legs after seeing the size of that snail. Maybe we should move this to worklogs if there are some more pics

I can also convert coil-overs over cheaply. Whats your location?
