Hi, I have a ramp of carb from a gsxf 750 and I am wondering if it could be a good upgrade to remplace my Weber 32DIR. Is there some power increase to hope ?? Thanks and sorry for my English .

More peak power but less useable power as it will all be top end and they require more maintenance and setting them up properly is harder.

It's for a drift car not a daily so top end power is fine and maintenance too. I want to have the most of my 1,4 because i don't want to swap i'm affraid to break the propshaft with a 16v swap. I will keep my 1,4 for practice and change car when i get more experience.

But a couple of HP more could help

What i've done:

- smaller wheel radius ( 175/50/13) soon i plan to use 165/55/13 on the rear
- fully stripped interior, no heater
- maintenance obviously
- bucket seats

What i've plan to do:

- lowering and stiffening suspension
- PU mounts
- hydro e brake ?

Power upgrade:

- Bike carbs ??
- Cylinder Head Porting & Polishing
- Other idea ???

My goal is to reach at least her factory power (70hp) but a 80-90 would be nice.

I would go with a single weber 45 DCOE for the carb

Do what porting you can that is effectve and a cam upgrade

I already have the mikuni Bike carb. And do not want to invest too much on the 340 just maintenance stuff and "free" upgrade because i do not trust the propshaft. A weber 45 DCOE isn't cheap

I found someone that did it on a c2j so it's almost the same as a B14 4e:
