Hi Guys,

I've spent the weekend reading loads of forum posts, but there is so much to take in I'm finding it tough !

I'm after sorting out going FI, but in order to do it 'right' Im going to do it in stages.

My plan was to first -

Stage 1
Fit uprated fuel pump - Walbro 255 seems to be a favourite
Fit fuel pressure regulator -
Fit additional EMS system - Looking at a Greddy E-manage Ultimate
Fit uprated injectors - This is where I need help !

And then, Stage 2

Turbo, Manifold, Downpipe, intercooler etc.

Now, firstly a couple of very quick questions

1 - How on earth do I work out what injectors to go for? my end goal is probably somewhere around 300-350hp, but I want to make sure whoever does the mapping doesn't say 'cant get it to work, injectors aren't good enough' I've seen plenty of options around, it would be good to know what people recommend.

2 - Subject to me getting someone to map it after fitting stage 1, I assume there are no 'risks' in running this lot without a turbo? As I understand it all I'm doing is improving the standard fueling setup, worst case I'm running a bit rich....

Appreciate your help guys, if anyone could volunteer to help over PM that would be superb.

Thanks again

 

Injectors and engine management are the last things to add. Your car will run like sh.. with those injectors and no tune. Get everything installed and either tow your car or limp it their with turbo installed but no injectors and emu. Do not go over 3k rpm. You do not need a fuel pressure regulator either.
Bosch 725cc injectors are the best size for you and have the best spray pattern period.

 

Do you guys know if S2K use regular Bosch sized injectors/connectors or some other size?
IIRC the are smaller and need bigger holes in manifold/rail but I might be wrong.

 

You can order those injectors specifically for the s2000. They fit great. PM Evans tuning or another vendor and get the plug and play clips.

 

if you need injectors and fuel pump, www.xenocron.com, has a good deal on combos
