G13B & Carbs Saw this thread again so thought I should post something about my experience..
Okay it's + 1yr since i plonked the G13b engine about 8K kms now,
Here's my story so far;
Intially was running a single carb, Single carb is useless doesn't work well with g13b, the mixture is insuffecient for the 16v g13b, especially the esteem mikuni carb stock config. Hence went in for a Quad Yamaha R1 Carb with custom inlet manifold. The performance of the car was great initially but the problem was the manifold-carb connecting rubbers, they have to be Yamaha R1 OEM/high temperature resistant hosing, else others just loose shape or break and you end up leaking the air fuel mixture. Later I ran into another issue, that the engine compression had come down drastically and piston was shaking if you try to shake, there was some noticable play, and a lot of carbon had deposited on the piston, rings etc. May be the car was running rich! R1 carbs have to have 2-3psi FP!! anway i had to overhaul the engine. Since the Quad carb is such a niche thing I feel i need to really learn/find a expert on it! Now I came back to twin carbs and the carbs are working great, it's even great that I can install AC because there's vaccum advance in our good old Esteem UCAL/mikuni carb!
R1 carbs dont offer that. I want to install and run the same quad carbs, but the thing is i need some who knows how to setup this.
I didn't want to go MPFI because i had spend a lot....moreover my car was carb esteem.
So to all, dont expect the car to be fast & reliable, it would defintely be fast but to make it reliable u need to sweat it out!! And not all tuners in bangalore are experienced they are also on the learning curve! atleast with whom i worked!
Enjoy your engine transplantation!
