Is it possible to get a G style head on a 5EFE? I think I have seen on TO a guy using a 4AGE(bluetop) valvetrain on a 5EFE. All he had to do is cut the valves a bit becouse they were too long. Im assuming theres a lot of custom work on such a thing like this. I wanna know how much work is involved or if this is even possible.
short answer: NO
there was never a 'G' head made for the E series
i am willing to bet that the cylinders on a 4age are not centered in the exact spot as a 5efe
No as t_cel_t siad they're has never been a G head for the E series motor. The bores are bigger on the 4age head and the water and oil ports will not aling together. So you can see for your self compare a 5efe and 4age headGasket. The guy on TO is using the 4age valve train not the head..
The Answer is NO
well first it is possible, just not easy by any means, the difference between a "F" and "G" is:
G = twin cam (wide angle, 45 degrees or more between the intake and exhaust valves)
F = "economical" twin cam (narrow angle, around 22 degrees)
If you can some how either make a head with the same dimentions with wider ports then a 5e-ge can be obtained or if you are realy crafty you can mate up one of the A series heads with the E series block assumeing you make a custom cuplar.
man what crawled up your tail pipe, about anything is possible, how do you think hot rods were made? mixing ford and chevy and who knows to make a bad as ride. if it doesnt defy the laws of physics it can be obtain, dont be so damn closed minded. pointless and as hard as it may seem, doesnt mean it cant happen
relax... i run into this sort of deal all the time in my kung fu class. if you feel he's being close minded, let him be. no point in arguing about it. it's just going to ruin your day to keep at him with it.
but IMHO, i don't think the headswap is worth all the work involved. i'd rather just swap in a more reliable motor instead of building a frankenstein of an engine. now if it were a honda, i'd be all for the frankenstein build, because most/all the parts are already compatible.
Yes there is somone using the 4AGE valvetrain but I think thats about as good as it gets. I think that would be alright though, especially if you had some porting done on the head, the benefit would likley be similar.
That being said, I wonder if it wopuld be possible to bastardize some kind of VVt system on there too ala 20 valve engine, even though you would only be using 16 valves, or mabey you could just use the adjuster bit (for the VVT)on the regular 4AGE cam... I dont really know though only because Ive never had one apart to look at.

no i agree, it would be alot of work for the power you get out of it but i am not going to rule out it being able to be done

a coupler with the "E" block size on bottom and "A" head size on top with ports would add some displacement aswell. and as for the VVT its all about the head so a 20 vavle 4a-ge head would work as long as the timing belt is big enough for the mod and you make a new cover for it.
well nothing is impossible but this is one of the worst ideas i heard yet. A cupler ??! what about the cam timing and the belt? as for making a head from scratch it ain't gonna be cheap and I highly doubt they can make the desing for DD cause of the water ports. And for the power gain.. why not 4age swap or something. and i'm not being close minded you just gotta know which project is worth it, and this is def. NOT
i know this all i am saying it could be done. i will let all the people that think if i make a "G" style head it will make me go faster have hope thats all
both make sense... but ya, seems like i'll most likely turbo sometime next year... gotta make some real estate sales soon, and get a luxury for a daily driver... then i can turbo the seo and go all out like i've been wanting to do with it.
speaking of which, JDM - how's your car holding up in the tropical weather of Tampa?
sorry stealthseo but that shit about the coupler made me laugh so hard, of course you can have a new head made from scratch but that coupler shit is just so far out there it is, [shakes head]. are you talking about some sort of adapter for like a tranny-to-block or something, because i dont think anyone has ever done anything like that.
you would have to run crazy boost just to get it to go anywhere, with the head all jacked up there you would end up with like a 2-1 compresion ratio, ha ha ha. I mean, you figure this adapter plate owuld have to be at least 3/4" thick, minimum.
