hybrid engines

[dj_chetti]

ok now i know that the most well known toyota hybrid engine is the 7AGE, but has anyone out there tried to bolt the 20v head on anything else?

i was thinking a good combo would be a 1rz or 2rz with a 20v head, if, IF! you could do it, the reason i say, is i don't know a great deal about the toyota motors...

[hatzo]

dobt the water jackets , and head studs would even fit.

Then the cylinder spacing , ect


Get a 20v Head gasket and try if you must.

i have neither a head, nor gasket nor motor, thats why i ask, but cheers for ur input

wont work unfortunetly, but wil work with any A series engine, putting it on a 2Ac block would be interesting...

[dj_chetti]

7afe, however you lose revability with it over a 4a bottom end

I got to go to bed so I wont be able to answer any more tonight but Trev I would like to hear your thoughts

It would need forgies and rods for it to be a reliable car on boost, as boost you need revs and the 7afe shits its self with a 70kw motor let alone 120kw with boosta powah .. None of this hope it doesnt blow up shit..

Thats one of the things i wanted to do but i was told its impossible because of the overlap the head would have with the bore.

The reason that the 7afe isnt a revvy engine is because of the low hp & toruqe range the engine has, There is no point in it revving any higher, The 7AGE we have at work has had quite alot of work done to it but revs happily on the 8800rpm limiter.

well I doubt there would be an issues with having extra overlap of the head, I mean its just extra squish area right? also I really know little about this but I thought it had almost the same bore but a significantly short stroke?

when I meant you lose revability I was being really vauge and I was thinking exactly what you have pointed out, from what I hear theres not a whole lot of point reving it past 6500

The engine at your work sounds like fun
