throttle body

have a spare throttle body in my garage and were just wondering with it being sat there what i could do with it to get a bit more power etc

what does a larger/modified throttle body do????


cheapeast/best ways????

not much you can do with stock one as far as i know...

The gains would not be worth the effort...

so if any what does a larger throttle body do
i havnt a clue on this subject an are wondering the beneifts in power and bhp or anything else for that manner

in theory it lets you get more air in
only realy need it if its serious turbo or n/a, but if it was serious n/a then you would have itb`s so its a bit crap realy, has it still got the tps, factory settings on it?

There are some advantages to upgrading to the sr20 throttle body throttle response is better and it also feels a bit more torquey up hills. Sounds great too alot more burbling

has stil got the tps on it an set as standard seettings as i know of really

jus calibrated ma tps and runs a lot better

i would keep it as it is mate you never know when your gona need a spare tps, or someone else for that matter
all of quotes of the added power etc on a near std engine is just placebo, iv tryed it on the rollers years back, no extra power, tourqe etc, just a very small shift in the tourqe curve to the upper end

hey, once fitted the sr20 tbody, have u fit a fuel pressure reg.??

will run poor of fuel with this mod? how much pressure in case is needed??

the 60mm sr20 tb is to big for the standard g13b, if you do go bigger dont go any bigger than 52mm

So fitting a cultus intake bore matched to a 60mm tb would need things like:
cams
cam pulleys
crank pulley
chip
header
exhaust
Fuel Pressure Regulator...
In order to run properly?
Anything else i missed lads?
This is just for my own set-up but should help others.
