4A-GE, how much h/p and torque

[Donald]

I have seen several different sets of figures for the horse power and torque output of the
4A-GE engines. I am particularly interseted in mine ('89). I have seen figures ranging from 115 to 125 hp and torque ranging from 97 to 115 lbf/ft. Does anybody know for sure what are the correct figures?

as far as i can see 4AGE your generation is about 130hp and if you have the Silver top 2nd Gen i4AGE s about 160HP...4 AFE is about 115HP

JDM is 125 to 130 but USDM is 115 to 120HP with 107 lbs/ft...

160hp crank

Thats only for the JDM Silver Top. The JDM Black Top is 165 hp I think.

As well the North American AE92 GTS's got the better 4AGE in 90-91.

which one is easier to modify?

Donald, forget these guys as obviously they only know what the read/see on initial d.

As far as I remember in North America

84-87 4AGE (Bigport) was 112-115hp
88-89 4AGE (Bigport) was 115-120hp
90-91 4AGE (Smallport) was 130hp
Put either one on a dyno and you're lucky to get 88-100hp


The JDM ones are a little different because they were MAP sensored instead of AFM sensored.

The Silvertop and Blacktop are best to modify since they are newer engines (92-98 approx.) and they have more power to start with.

It really comes down to a preference and money, Silvertops can usually be had for a lot less than Blacktops (sometimes even half the cost). However, if you look hard and are lucky you can find Blacktops with a 6 speed transmission, which would be cool.

There are a number of threads and stickies on all of the 4AGE engines, just search for them, as well there is some good stuff on Wikipedia too.

Hope this helps.

Well.. yes and no, depends which way you look at it, ST/BT parts are harder to get as they were never sold in any North american cars, if you think finding parts for a regular 4AGE is hard, try finding parts for a 20V motor.

Ya Ren's got it exactly there! I couldnt remember all of the North American numbers, I was only talking about the JDM swaps available.

Thanks Ren69.
That is the answer to my question, and yeah I know that wheel horse power is about 15% less than crank shaft HP so dyno readings will be less than what Toyota claims.
