yoko · Jul 15, 2013

Hi all I have a t-jet engine and done the following upgrades
td04hl-13t turbo from garrett will run about 1.25 bar
2.5' stainless steel exhaust and de-cated it
stainless steal exhaust manifold
water/meth kit

the question is will i need a 4 bar fuel regulator or not?
another question will i gain a good benefit from fitting 1.4 16v starjet cam shafts?

Sorry i cant answer your question mate, but was the td04 a straight swap, looking to upgrade mine. Hopefully this will bump your post up the rankings and help

i am afraid it is not a straight swap you have to change the exhaust manifold and the down pipe
In my case the manifold was cracked (must be changed) and here in Egypt we don't have regulations on the exhaust so i decat ed my exhaust

And by the way I got the 4 bar regulator and i had to left egypt and when i go back i will get it remapped :slayer:

Can't see the starjet cams helping.

See what your RR man says, but if the car is underfuelling, best route (if it can't be mapped out -- that is, if your injectors are running too high a duty cycle) is to increase the injector size and make sure the fuel pump is up to the job.

My friend with almost the same setup gained 10hp from the star jet cams it shifted the torque curved a little and no noticeable gain in torque "i don't think it worth"
injectors the only injectors i know will fit are the Audi TT injectors and they are not available in Egypt and i can't afford new
