Hi all,

 

In the very near future I will be treating the Zed to a boost upgrade. I Intend to fit a Zedworld chip and jets along with a good quality boost gauge running 14 psi. I know its better to fit a boost controle module but as Im moving house, money is a little tight at the mo!

Have already fitted a mongoose, Apex induction and ACT clutch.

 

My question is, will I expect to see a rapid acceleration on the wear of the engine and turbos, splitting hoses ect.... Bear in mind most of the time the car gets driven very gently with the occasional blast now and again.

 

Engine has done around 90k miles and all parts are original as far as I am aware. All in good shape, never smokes or rattles when cold ect. Had the car 3 years now and no major problems.

 

Has anyone else fitted a boost upgrade to similar condition engine and experienced any problems.

 

Any advise would be much appreciated.

 

Thanks Andy

I fitted a chip and boost jets to my car but my car has done 80,000 miles more than yours.

 

My engine started to smoke about 2-3months ago but this is due to the more miles.

 

It is impossible to say how well your engine will take the upgrade. If done correctly the engine if in good condition should have no problems. The hoses shouldnt take that much more stress, but if they split they where going to split any way.

 

I would go with a boost controller if I was you. Boost jets are a very crude way of increasing the boost. Some people will get 14psi and some get 17psi with the same sized jets.

Hi stuart.

 

I dont disagree about the jets, they are very crude, however with a fairly low budget due to the house moving a boost controler is out of my price bracket at the moment and desperatly want more boost!

 

As with regards to setting the correct boost level with the jets I intend to fit one of the Data loggers which I use in work (Very accurate bit of kit!) , fitting a High accuracy transducer to the boost line and adjusting the boost level by changing the size of the orifice in the boost jets ( probably make my own) until I have a pressure of 14 psi. Can all be linked in whilst i'm test driving. I will then calibrate the warning signal on the GReddy boost gauge to just above this level.

 

Bit of setting up I know, but it should give me a accurate boost level. Be nice to leave the Data logger in there! not sure work would be so keen!

had no probs with mine, its a great way of getting power for bugger all!! ;) mine nearly done 100,000 miles now :dance:

Bought mine with less than 50k on the clock and boost jets fitted to 15psi.

 

Everyone told me to beware so I had them removed and went back to stock till I can justify the boost controller.

 

You'll have to make your own mind up.

Is it worth me buying a Boost Controller, all I have upgraded on my car is the air intake. Also how much does it cost to get one fitted?

 

thanks, Alastair.

Not really worth it yet mate, you'll just melt the clutch anyway!

 

Next thing to do would be the exhaust, then ECU then boost controller and clutch.

 

Oops, just noticed you're an auto, so don't worry about that for now. But you definately need to do the exhaust to improve air flow before upping the boost

yep and a new autobox shortly after :rolleyes:

Thanks guys.
