Hey guys this is my first post here on ratsun, and just for the record ive done lots of research and cant seem to solve my problem, so for those of you who are just going to say use the search bar....ive tried.
So i went from an l20b blowthrough dual SU carbs to an l16 draw through setup... The l20b never ran quite right (carbs didnt like the air flow) and i eventually blew it up and decided to do it the right way.
For the last week ive been building a motor, doing all my mock up and finally have it all put back together. Im Using a stock l16 (rebuilt) single carb intake manifold, stock cast head with a custom up pipe, a td04 turbo from an 06 wrx and currently ONE of my dual SU carbs...
The Problems: Throttle response is slow and not always the same, the car is shaking and vibrating really bad (checked timing, good, checked spark compression and plugs all good), inconsistent idle, it will idle sitting in the shop but when i drive it its all over the place, over all its running like crap... boggy and feels like its missing almost
Ill post some pics so you guys have an idea of what im working with, any help or ideas would be greatly appreciated.
Thanks
Casey
