Hello, So I have all this good stuff off now. Intake manifold, rail, injectors and I had a couple of questions. (99 Tiburon)

1. Can an aftermarket fuel pressure regulator be used on the stock rail?

2. How can I clean the old injectors? And, with what injectors should I replace the stock ones with. I am going to soon add a turbo.

3. After I replace the injectors to bigger size ones, will I NEED a different fuel computer right away, or will the stock ECU figure it out and give less fuel, till I get my hands on a SAFC?

If I get any help with these questions, much appreciated. I am doing all the work myself and on another note I also got the MSD DIS II figured out.

Thanks for the previous help with that! smile.gif

 

it depends on what size injectors you replace the stockers with as to if you need a new/piggyback ecu. i've read of some people using 10% larger injectors with stock ecus. if you're gonna get 440cc injectors, then you need a new/piggyback ecu.

 

No, No one currently makes an aftermarket fuel pressure regulator that will bolt up to our fuel rail.

You can soak your injectors over night in B12 Chemtool, or send them to www.rceng.com and get them cleaned and tested for $25 per injector.

What fuel injectors you should upgrade to depends on what turbo you get, what your engine setup is, and how much boost you plan on running or what your WHP goal is.

440cc RC Engineering have been recomended so far to me. Then with the 440's I need a fuel computer. SAFC? Is it a pain to install? Thanks for the advice. Random thanks for your suggestion. I wanted an SC till about a month ago , but got sold on the turbo idea.
I have not decided on any kits yet, but I am happy to see there is more selection now for our cars. I must decide on my WHP goal first. true.

Respect

PS I almost wanted to post this originaly in the help forum. ? Thanks for sorting it.

with the 440's, you can get your fuel issues sorted out with just an S-AFC. However that doesn't take ignition timing into account.

 

I have the MSD DIS II for the ignition.
I would like to see close to 300 whp me thinks.
or right on 300 would be nice. I have no idea of whats there now. I will find out soon.

 

u can make an adpater for pretty cheap that will make most aftermarket fuel regulators either mount 2 the fuel rail or remote mount on the firewall

 

you have a pic of this setup?

 

Tony!
This is what Viper is trying to explain.Look at my pic where you see my finger pointing at the metal Block off Plate

Random.....Bretton at Stylingperformancecentre in Australia is now carrying the latest F.S.E. (Malpassi)adjustable fuel pressure regulator for our cars!.They now incorporate an attached gauge,& are small enough for postal despatch to be easy.
I have had one of these fitted to my Scoupe Turbo for the last 2 years (albeit without the gauge)& wouldn`t be without it!.
Cheers, Nick.
