Thanks. I need some help i want to install a lambda with manometer and modify my carburator with bigger giglers . Can anyone give me a hand?

 

[andybond]

ambda with manometer

I used one of these : MTX-L PLUS Digital Wideband Air/fuel Ratio Gauge

fy my carburator with bigger giglers

I think this might be a translation thing. Giglers should be jets.

We can help on this as well.

We should definitely change the word jet for Gigler

Lol yes sorry my English . What i mean is that i want to modify the carburator in order to gain more Power .

 

[andybond]

Do not get the group A carb. Its a waste of money

You need to monitor your AFR with the kit I listed then tune your carb to suit

Thanks for the tip . What do you sugest so i can get a good proper tunned carburator ?

???

youll need to use the afr gauge to see your fueling and then adjust the jetting to suit

 

[Tiagogttportugal]

Ok but in your opinion should i also get bigger jets or try it with the carburator stock ? thanks

 

[Mark Davis]

It depends on your set up.

You’ll mainly need to change your first stage, second stage and a/c jet but until you have an AFR gauge fitted you will be blind. It’s a case of trial and error and depends on your current set up - Turbo, cam, boost pressure, fuel pump etc

 

[Tiagogttportugal]

I see what you mean, i already saw a few afr gauge kits and i think im going to buy AEM seems nice.
My current set up is turbo t25/t28 with complete 63 inox exhaust pipe; cam 275 ; boost 1.3 bar ; intercooler Double capacity ; stock carburator stock ( bigger jetts maybe???); fuel pump stock ... etc

 

[Adey]

id be surprised if its still going strong on stock jets, with that boost and setup

 

[Tiagogttportugal]

Its very fresh i Haven't made him proper millage ( sorry i dont know how to say it better ) cause the motor have Been all checked and also have reenforced cillinder Heads and head gasket. I Only have made 800km at low speed but when i push it the turbo kicks in at maybe 4000 rpm its a bit high im not uses to the bigger turbo. The guy who made the job is a good mechanic but doesn t have to much knownledge on performance or tuning. Thats why i need some advice from you guys .

Best thing to do is get your AEM kit fitted and then come back and tell us so we can guide you.
