basahboy said:For starters no need TODA or JE forged pistons...you can increase the comp of your B20B block in a lot of ways..but again, you want reliability, it comes with a price...block b20b with 85mm JE piston is being sold at N1 for about 4.5k...you can check with desmond...with TODA, more expensive...my mechanic uses a 1.8L block with 85mm TODA piston...plus the bore charges close to RM8K...
i suggest co with the basics and ask your foreman to increase the comp to 12.1 (if you want)...play around with it and if you are not satisfied then go for forged...again...putting in the piston is not as simple as plug and play...it is a complete overhaul and engine balancing is a must...so again, do you want to go through it again or just one time terus kari taruk semua...your call....for me, stick with the OEM (more reliable) and buy Haltech or ApexI FC...they can tune your car up to 20% increase for NA....so with the recommended set up you can get about 205- 210whp...take that against a 20% decrease to the crank you get...250hp...BUT your torque would be gilerrr.....
Save all the money to get one EMS? All, stock parts and one EMS can get 210 ON WHEEL HP?? OEM parts especially the crank and con rod bearings for B20 got wear out easily. Summore, increasing to 12:1 cr is not going to be as easy as said. Also, 1.8L block with 85mm TODA piston??
