new to the Z world, and to this forum really.

 

will be upping the boost shortly, on previous cars iv increased the boost by usung a dawes device (manual boost controller valve thing)

 

on here people use "boost jets" (i thaught thats what you called manual boost controllers, but ive found out they are just mig tips)

 

anyway, do you use boost jets as they are cheaper than daws device?

 

or easier? as if you had daws device youd need to make sure they are dead the same, as 1 turbo could be running 12PSI and the second turbo 16PSI.

When I had 1.2mm "boost jets" in mine I'm almost certain I was pushing 16+PSI which I'm also sure is why my Z feels slower now after fitting a Profec B II EBC set at 14.5PSI :(

Before changing the boost, please please get an uprated chip from AndyP or John Dixon!

Get a Profec B Spec II boost controller mate. Only £200 and a chip. If you dont get a chip you wont have enough fuel and get detonation and a blown engine.

yes i know thanks guys :)

 

car is standard at the mo.

 

getting it chippt first, then boost jets, along with decat.

 

im after 15PSI at the most.

 

was going to get a 1mm mig tip/boost jet.

 

this good? or would you advise 1.2mm.

 

remember that de-cating will raise it slightly?

Wouldn't advise decatting unless you have new turbos, especially running higher boost.

1.2 minimum to start ;)

But as Si says don't advise decatting although I have :)

1.2mm will give you between 12 and 14 PSi and 1mm around 15/16 from memory.

Yeah about right Si but all cars vary

Sure. Compression and turbo condition will dictate the end results.

cheers guys.

 

il buy 1.2 & 1mm.

 

they are only like 3 quid for a set, so dont mind playing about.

 

decating is opening a can of worms, but someone said the recent poll sugested that 80% of people who decated saw no smoking issues.

 

if car smoked on standard boost, or on idle id be a bit hesatant. but cars done 75k miles, and turbos "seem" solid.

Didnt i read somewhere on here that the turbo's are normally good for 60K???

Old wives tale. Turbos will last as long as the person that looks after them. There are guys in the US that are ovrt 140k on original turbos. Plenty of UK cars with 100k with original tubs.

cheers guys.
