4AGE or 20 Valve

I am looking into an old KE20 or KE30 rolla purchase and i am interested in making it look nice and have a bit of balls. What would be the better option for me the 20 valve engine or the 4age.
does anybody know what the standard kw at the wheel for both would be and the approx engine conversion costs involved in each
thanks in advance.

20 v is more advanced, vvt, quad throttle bodies and 5 valves vs 4. Both are bloddy good motors, either way u will be happy whatever motor you choose. 16v has parts easier to get, 20v has more power on it. If you go 20v and have the money, go for a black top, they are a little better (map sensor and more recent). I had a 4age SX and upgraded to 20v silver top and did notice the difference (20v is faster) but i still love the 16v, and ifi could do it again i'd rebuild a 16 v with an after market ECU and quad throttlebodies on it.
good luck with the decision

a 20V is not worth it over a 16V

^famous quote from the twincam.org forums
I would stay with the 16V, it will be cheaper to buy, cheaper to install, and bugger all difference in power. DO NOT believe what people say regarding toyota's quote power figures of 116-120kW. In real life its actually 106kw for Silvertop, and 108kW for blacktop.
Also for installing these RWD, there is a fair bit of mucking around required for the dizzy, water outlets and plenum.
Dont let this discourage you from using the 20V though, they are a good motor, but they arent that huge over a 16V.
For instance my $100 smallport 16V which came out of a bin has clocked a 15.8 1/4 mile, and 69rwKW (4.11:1 diff) in my AE71. In a KE20 your 1/4 times would drop cos of the lower weight.
If it were me - i'd go the 100kW 16v again, but i would probably add a turbo to REALLY scare some people.

20V is not as hard as everyone makes it out to be. I found it pretty easy. If you decide to do it, let me know and I'll help you out to make it as easy as pie
