Excuse my ignorance as I am just reading/learning and sorry if this has been covered before but from Wikipedia;


The 1992-1993 engine has 185 hp (138 kW) at 5800 rpm and 189 ft?lbf (256 N?m) at 4600 rpm. 1994+ have 200 hp (149 kW) at 5800 rpm and 204 ft?lbf (277 N?m) at 4600 rpm. There is no mechanical difference in the engine. In an embarrassing move, Toyota inadvertently created an engine competing with the more performance oriented 7M-GE and 1JZ-GE installed in sportier, more luxurious cars of the time. Because of this, both stock ignition timing, and fuel tuning were set more conservatively than normal capping power output.

Does this mean that a 92 v6 engine is being held back or deliberatley underpowered through the timing/fuel setup?

Have you changed your timing/fuel after the v6 transplant?

The head is also restrictive, hence the FE in the Toyota range which means economy. The GE (e.g. 3SGE, 4AGE, 7MGE, 1JZGE etc) heads are all performance heads.

By porting out the FE head, and mapping the car up properly with correct A/F ratio (I think they run a 13:1 ratio out of the box which is crazy rich) and fitting more free flowing exhausts, it's easy to pick up 50bhp. Well, relatively easy.

25-35 for the heads
15-25 for the timing mods and fueling
10-15 for the exhausts and y pipes.

Not only is the engine powerful ... it's damned strong :D

By timing/fueling mods you mean the 17 degree timing & 5 clicks on the AFM mod?

ha ha , that almost sounded as if I knew what it meant!

[lodgeman]

i've done that mod scott on my mk1 and it really does make a difference!! plus i also have the acis permanently open:whistle:

[GaryA]

Now we know why the first one :blowup: lol

[lodgeman]

first one didnt last long enough to change the timing and afm:whistle:

[lodgeman]

:thumbsup:

Wayne, let us know how it goes eh? Looks easy enough to test leaning the ECU out with a few clicks.

[foxy-stoat]

yeah no worries....gonna get it dyno'd soon.

so i'll get a before and after power too, if its quick n easy !
