Re: I need help to make an upgrade (jettamk__4)

what you'd want for auto-x is vastly different to what you'd want for 1/4 mile. if you want to do well in one, you will have to compromise for the other.
pick which you would be your preference.
injectors should be matched to your software. pick the software, and then buy the software that is paired with it.

Re: (jettamk__4)

I would go with the gt2860rs, to use the full potential of the gt2871r you would want to upgrade your rods plus I don't think Genesis injectors come large enough if your looking to use twin spray injectors, I'm not sure, I found bosch ev14 twin spray in 650cc at injector clinic but that's boarder line to cover 450+hp and there's probably no software for them, so standalone would be needed, if you have the time and money get the gt2871r, if you don't! get the gt2860rs better for autox, wont be the fastest at the drag races but fast enough to still brake stuff

I would go with the .63 t31, external wasegate is better
injector clinic has a bored out ev14 550cc that is 650cc
here's a link for the injectors

Re: (Autoboost-tech)

Why would you go for .63 t31?
If I choose external watesgate I have to use turbo boost controller

it would work for both your racing, autox and drag, good top end and still spool fairly well, tried to hit the middle from your description of use, external wastegate's wouldn't need a boost controller unless the spring rate was wrong for the boost you want, you can change springs! can't in most internal controllers! externals are more accurate in my opinion, the advantage to internal is ease of install and for tight install situations.
cheers!

Re: (Autoboost-tech)

I have two doubts it is necessary to change the maf for 3" and the intelpipe that to be 3 or 2.5 inches
With the injectors if I put them of 550cc works well or needs 650cc
I need to chance the manifold where can I buy. In ebay could be good
Can you give me some links.

I drive daily

Re: (jettamk__4)

the kinetic one has external wastegate setup, a 38mm wastegate will work great, I like TiAL products my self, a Bosch 044 inline fuel pump will work, I use a Aeromotive regulator, you will just need what is recommended for your upgrade software, 3bar is used most, c2 software seems to work great for a lot of people here

Re: (Autoboost-tech)

In my city only there are 3 dealers of software who are giac, apr, revo which of these work better.
When i bougth my car I don´t know that was in stage2 may be in 1, My question is
If I buy stage 3 What happen whit the stage in ecu .
Is delete for ever for my ecu
I don´t know what softwarte is.
Let's suppose that in the future I want again stage 2 ´cause sell the car and I extract the repogramacion of stage 3 it stays again stage 2 or software stock the ecu.

Waht do you think about these fuel pump and fuel presure regulator
because I´m worried to spend a lot of money of gas because I drive my car daily.
