3SGTE with a 4AGE 20v head?

will it fit
is it even worth the effort
will it have any performance benefits?

was just wondering cause there isnt a 20v head for the 3sgte and i figured the 20v system might be useful on the 3sgte

if this is stupid tell me.... nicely

I spend a lot of time working with both engine types as i own a ae85, and my old man (who posts under this login as well) has 2 gt4's. And there is a substantial size difference between the 2, but it could be done at a stretch.

Jun have taken 20v heads an put them on a 1UZ so anything is achivable, but the amount of modification and etc needed to get it there was up in the thousands. Bottom line is its not worth the effort.

Your better off with big fat cams and a huffer, ecu upgrade and several thousand dollars saved from not doing this mod haha

not certain, but I'm pretty sure the bore is different, let alone the spacing between bores.

Also little advantage in having more valves, from what I've read the 4age 20v head has a few downsides to it when compared to the 4age 16v head, something about angle of intake entry or some such... but that may only be an issue for NA.

If you have a 3sgte, the better head would probably be the dual vvti one from the Altezza, but I'm not sure it is compatible, some reading on it suggests that some of the required oil galleries are not there on the previous generation blocks.

you have a nice car, try to be less erratic with finding upgrade choices

huffer?

turbo... but I think you already have a turbo car right?

WOFTAM. You'd need some sort of spacer to make it fit, theres like a 4mm bore difference to start with. 3SGTE heads flow enough to make good power without doing out there swaps.

lol never heard of a turbo referred to as a huffer. yea its a st205

how would this work, thinking about the where the exhausts and intake would go.

thats why
another option is to dump the st205 internals into the beams motor bolt the turbo on etc etc

different = expensive.

you dont need some crazy hybrid engine to make pant soiling power levels, theres lots of proven upgrades out there for your engine.

when the bonnet is down no-one cares how many valves it has, as long as it goes hard!

Read it in a japanese option magazine (not so much as read but looked t the photos and went WTF?).

It took heaps of work i know that much, like HEAPS. Google it and see if you can find it.

Why do you think that 20v head flows better than gen3 3SGTE head?
It does make ~200Hp in NA form (with assistance of fancy manifold and VVT), which is better power per litre than 20v (because it actually makes that power unlike ~140Hp of ST or ~155Hp BT).

if you want a good head for a 3sgte, get yourself a Beams one. HAven't had a good look at a black top, but the red top heads are real nice. Having said that there's a guy doing 10s on an unported gen 2 head in an mr2, so even those hideous things seem to do the job pretty well (but maybe he'd do 9's on a beams head

)

Oh yeah, don't be caught up in the more valves = more betterer hype.

it wasnt that i thought it would it was just a crazy idea that pop'd into my head.
im a bit like a mad scientist with some of my ideas.
You'll get used to it :p

Go the crazy ideas!

If someone didn't think of them we'd all be cruising around in something sensible like a corolla hatch. And every sports car would be a GTR Skyline...

Also.. it's only a crazy idea till you make it work. Then it's pure genius. And if it works really well, it becomes the next big craze.
(e.g. drifting a taxi!! Who would've thought that competitive drifting in NZ would truely begin with taxis!!!)
