Best jets

[MR TURBO]

Guys just a quick question what do you think are the best jets to change to from standard plus i aint looking to run no silly boost either.......Suggestions????

[car.crash]

:confused: no answer can be given without saying what spec you aim to achieve, and even then its guesswork without a AFR.

Hey mate... 180BHP isn't that easy... if you look at my car's specs on my profile you can see all the mods I did and I run 165BHP/220NM on the rolling road @ 20psi with my T2-T25 hybrid. I recently put in a gp A carb, just to test it AFR-wise... and it suited my car just fine without modifications. On my other std carb, I changed the a/c jet to 0.9mm and drilled the 2nd stage to 1.2mm. That's it! :coffee:

Is the statement above true????

[Brigsy]

Southern carbs will supply jets if you need them.

Why don't you buy some micro drill bits & do yours as necessary;)

Have you tried southern carbs???

I think you can still pick up standard main jets from Renault aswell not sure about the a/c jets though

Just looked at all your mods, i swear theres people running standard engines, just with bigger turbos and a few other subtle mods and are geting 180

Well it sure feels like a lot more than 165... maybe that dyno wasn't very reliable ;)

dealers still sell the jets...most tuning specialists can order them into stock, ....

or,,,you drill, solder and grow your own

oo im intrested

if i want a 1.2mm 2nd stage, as said by jantheeven, what size would a standard jet be?
i really want to find out what this carb is running as it fuels loads, and i belive has hesitation before boost due to this, mpg 16/18mpg on a good day, that cant be right for a "standard" carb or can they get that bad if say the mixture screw is wrong?
what is the base mark like when on bike cabrs itll say something like" turn in to stop. 1 1/2 turns out"
:agree:

[James5]

2nd stage is non removable unless you fanct drilling it out and tapping an a/c jet in it's place but if you go wrong it's a new carb body you will need. The standard 2nd stage size is 1.0.

Don't fettle without and afr gauge though matey.

[R5GTTRaider]

oh i understand that, tho whats the easiest way of finding out if its over fueling, or whats the best wy to check the jets? is it part on the o/s of the carb that contains the jets?, the a/c jet which i pursume sits under the carb top wont come out!

Easiest way to find out is taking it down to an MOT station and stick and emissons tester on it or buy and AFR gauge / setup i.e. LM-1 so you can see what it is doing through the gears and through the rev's.

The a/c jet as you say sits just under the carb top it is just small flat head screw driver type and just simply unscrews.

When you get your micro drill bits, you can try different sizes in your main jet and air corrector and see if they are standard. If you put a 1.2 drill bit into the main jet you would hope it would be pretty tight if it's loose then its been enlarged:)

:agree:

The standard size Jets for a solex 32 Dis should be

1.25 A/c
1.00 1st stage
1.00 2nd stage
1.20 Main Jet
1.7 Needle Jet

I am sure there is an article for all this matey might be worth looking in the article section when you come to play with jets

So this is not a technical dissussion??? I'd like to know what you call it where u come from???:sad2::scratch::sad2:

[rs250nut]

Get something to measure the drills with aswell.

[MR TURBO]

Ok my micro drill bits are on the way......I'm gonna take the jets out of one of my spare carbs and see whats what and have a little fettle!!! If all else fails southern carbs or ktec here i come :D
