Corolla 1.3 Power Differenc's?

[Harvey-aw11]

Does anyone here know what differences there are on the AE101 (i presume? The 92-97 shape) 1.3 4EFE engine? Why are some 74bhp and some 87? Reason i ask is im wondering whether its a fairly simple few upgrades for my starlet 1.3 :D Maybe just like the ecu for example. Thanks;

well i think this is releveant. I've read that the starlet gi had different ecu and has 100bhp, it is probably in the ecu but you can try adding induction kits exhaust and other bits and bobs for a few bhp.

The engine size altered slightly as well, the 87 BHP moved from 1296cc to 1331cc

That must be one reason for the increase in power...

1296cc is the 2E, 1331cc is the 4E.

2E was a pure single cam (12valve),

4E is a 'dohc' - not true dohc, & 16 valve, with the -F type of cams.

(I have had both engines, and currently a 4E-FTE).

Interesting. Why 'not true DOHC' NDR008?

The idea of a twin cam concept is a timing belt linking the crank shaft with the intake and out-take cams - right? That is how Variable cams came about, by having one of the cams self rotate to vary this relation.

However - toyota -F heads have a timing belt relating the crank shaft with 1 cam shaft. The 2 cam shafts are then meshed together under the cam cover.
