4age 3sge valve face dimensions q

[crispy'86]

I'm thinking of using gen 1 3sge valves n one of my 4age big port heads, so does anyone know for fact what the 3sge measures in exhaust and intake valve?? I've measured 4age ones and intake 30mm exhaust 25mm on the face , i.e. what you see whan you look at the combustion chamber. Before anyone says, "go the gen 2 3sge they've got huge valves etc" if it isn't much difference in diameter to compromise the clearance between the intake and exhaust valves then it's going to be a cheap swap. As in spending next to nothing in my terms on buying parts

i have all the dimensions written down at work... will try remember to bring em home lol

3SGE valves are longer as in the stem length, and the keeper groove is too high up to be used on a 4age, try 3SFE valves, they are slghtly larger and have a similar stem length, ive used them in my 4AGTE.

Okay , so how much longer in the stem are 3sge valves than 4age?? And 3sfe valves, anyone got any?

[CAMB01]

I think from memory there about 25mm longer

What difference are the faces of the valves like to compare them with 4age valves, and importantly would just any 3sfe valves do or do they have to be out of an sv30 camry or something like that?

[CAMB01]

I bought my valves brand new but not genuine. I just asked for a set of 3SFE valves and gave them the dimensions i found in a book.

I think the valve heads are 1.5mm larger in diameter.
3SGE valves are about 2.5mm larger in diameter.

did it make a huge noticeable difference using them??

[CAMB01]

Dont know, the engine is sitting in my garage on my engine stand, run out of funds to get it in the car. (plus i need a new car )

[crispy'86]

the dimensions in the book you stated, how did you get those? workshop manual??

[CAMB01]

Cant remember what book it was in sorry.
Think i got them through either Appco, or segedins.
