Hmm... U wanted a twin cam right? How about 4G91 (1.5 DOHC) or 4G92 (1.6 DOHC). If u wanted a more spirited drive, I recommend u to swap to 4G93T (1.8 DOHC + Turbo Charged). The choice is yours...

why go DOHC when SOHC are good also?

Thanks for the info.....
But if I'm not mistaken 4G91 and 4G92 engine mounting were different frm Iswara and required modification on the mounting. Was trying to look for the twin cam engine which need not to modified the mounting. As i don't have any idea on the model that can fit in iswara.
Can't upgrade to 1.8 due to original were 1.3cc only....:tongue:

Hmm... If that's the case then u have to do some 'rojak' modification to ur engine la. I'm not sure whether u can just swap the head from SOHC to DOHC or not.

Yup! I agree. Even I myself still using the legendary 4G15 SOHC with a Stage 2 modification. I think the most powerful SOHC, 4 cylinder, 1.5L N/A is D15B from Honda. It produce power around 110-120hp on the cranckshaft for a stock spec.

Stage 1 usually involve a mild mod which is good for daily use, such as sport springs, drop in air filter, extractor etc. For stage 2, it involves a bit aggressive mod compared to stage1 and it's suitable for track and daily use. For example a high-cam, hi-lo adj absorber, cylinder head port & polished and so on. It's actually depend on what stage are u referring to, whether it is specifically engine only or for the overall car mod.
