1) what are these "beiges" i keep seeing everybody talking about??

2) whats the diference between throttle bodies and carbs?? Which is better or is it down to personal preference etc etc

fairly new to all this so its all a bit confusing to me lol

cheers guys

i can just about anser your first question mate, beige's are the beige colourd injectors and can supplier more fuel than the stock blue ones, i think beige's are needed to stage 2 spec

Throttle bodies and carbs...

CARBS: as in "twin" carbs basically means you have one "throttle" for each cylinder (on 4 cylinder) so therefore the engine has the potential to flow much more air through the head, therefore more fuel is added too by way of "jets" in the carbs.

Carbs are the old-skool way of n/a tuning but are tried and tested and do the trick, just need to be kept "balanced" and in tune quite often or they go out of their optimum settings and your car runs crap, basically!
Lots of exprtise needed to set them up correctly and as they vary in choke size, 40,45mm etc you have to choose wisely to suit engine size, spec, cams, cr etc.

THROTTLE BODIES: They are similar to twin carbs in that you end up with one choke per cylinder so lots more power potential (they even bolt up to the weber dcoe twin-carb inlet manifolds too in the case of jenvey etc) The main big difference is that they run with modern engine management and fuel injectors so are more emission-friendly for modern cars that have stricter mot standards on emissions.

They are also more able to tune more precisely so will maybe get a (little) bit more power but to be honest there's not much power difference between properly set-up carbs or modern 'bodies.

Throttle bodies can also run in "closed loop" with engine management and lambda sensors so will stay in the optimum setting unlike older carbs.

NOISE! Be aware that either of the above make one hell of a racket so think wether it's worth the trade-off if it's your daily driver! - my Rs1800 was hell to live with on the motorway and long journeys when i had my 2.1 connaught lump on 45mm jenveys- i used to get ringing in my ears!

Good luck mate

cheers jim. explain alot.

what wud u prefer. you said you had jenvys (t bodies) wud you in hindsight go for the carbs.

which are cheaper to install/run etc or is there not really any difference between the 2 provided both are set up correctly

once set up tb's dont need touching again. carbs need resetting up every now and again. last time i check they're about the same cost initially. but it wont stop there once youve been bitten by the bhp bug youll want more and more

Definitely without question Throttle bodies on a modern car the ONLY way I would go!
The main reason for this is that, as mentioned before they stay operating in their optimum range for a lot longer than carbs so you don't lose power/fuel economy all the time (you're gonna need every mpg you can get! )

I ran my jenvey 45's on DTA management, running in "closed" loop and they were just fantastic -2.1 litres, 220 bhp@7000, 179lb/ft@5000 was mental in my rs1800!

In a heavier car though I would go for turbo/supercharged power for more superior low down torque as my t-bodied engine was a bit "peaky".

Get a decent breather system on your engine too- it will need it.

Like i said before though get some ear-potectors if you go for t-bodies or carbs!
