hi guy..
im from singapore and im new to this site, interested in swaping my (92-95 civic D15B2 DX 1.5 92hp)engine to other engine or head to gain some low end wit more pull, can any pro here help mi wit it??
Current engine= STD D15B2 w/o vtec 5 speed tranny P06 ECU DPFI (EG body frame 4D)
* 1493cc
* 4 cyl, 16 valve
* SOHC
* 9.2:1 Compression Ratio
* PGM-FI (DPFI)
* 92 bhp @ 6000 rpm
* 89 lb-ft @ 4500 rpm
* Redline: 6800rpm

-Chaning to DOHC is easy to spot so NO NO in my country.

QUESTION:
-Does changing head gain more hp? D16Z6,D15Y8 or D16 MPFI head, which is better? (cheaper) kekekek
-Or swaping the whole engine to D16Z6, D15B or (ZC D15B wit 130ps) which is the best?
-Any pro can can help me list out wat is the best (buget) combination or which engine to swap to gain most power (low end).
-how much hp can i get??
