rs2 injectors........

[R31LLY]

i have read that the s2 is capable of rs2 power with keeping the existing injectors and fuel pump

BUT

My question is....
Can you use RS2 injectors on a s2 fuel pump or is that a total no go??

thanks in advance reilly

You can definitely not get rs2 power levels with stock injectors. Simple physics.
As for the fuel pump, the stock is enough, but it could be tired. It is not expensive and not difficult to replace, so why gamble?

im just on 034 motorsport bout to buy a 5bar fpr, 3bar vamap, rs2 replica injectors and i was not sure if to get a fuel pump,

im not sure on thier site which fuel pump i need though :-s

[R31LLY]

how can you tell if your fuel pmp is tired or cant you tell???

[prj]

You don't need any of these!
What kind of turbo do you have?

[R31LLY]

k24 hybrid

i got a chip session coming with mrc when they fix their 5cylinder systems, they cancelled my bookin on the 27th of last month :-(

i want it all ready for when it gets chipped up, i was not going to take the car so far but now i am

If it is k24 keep stock injectors. Do not fit a 5 bar fpr. You also don't need a vmap a normal map sensor will do. Much cheaper, I sell them on here for 25 eur shipped.

Who is going to map your car?

A turbo with stock turbine wheel will not run rs2 power levels. Talk to mrc before you waste lots of money on things you do not need. Stock fuel pump will be fine for your needs.

m.r.c tuning are ment to be doing it but they say its weeks til they will get thier stuff fixed so im looking into mtm (qs tuning)

i have a 2 bar wastegate spring and ive been told when come to fit it all need the injectors and a vmap sensor, my car is running quite slow at the min i think its in protection mode due to the wrong map sensor??

why what are your thinking my best option is??

[R31LLY]

ive had a k24 7400 or a 7200 hybrid turbo built 330bhp rated, m.r.c tunin gsaid ill need the bigger injectors

[R31LLY]

my turbo has the k24 housing, with a bigger inlet and better barings, with the k26 internals and they said it was a quick spool when they built it

So, let's break it down:
1) The Replica RS2 injectors do not have the same specs as the originals. They flow more (or it seemed that way because their latency specs are completely different) and have different latency, which means that they will be more harder to tune, but MRC can probably handle it - if they get the injector latency data... Real RS2's are better - they have lower latency, so better at low pulsewidths.
2) VMAP is just the same 3 bar or 4 bar MAP sensor in a nicer package. A 3 bar MAP sensor will be enough for your needs, since I don't see you running more than 1.8 bar of boost on that turbo.
3) The 5 bar FPR you don't need because it will put more strain on the fuel pump, and also screw up your injectors dead times completely. Stay with the stock ABY FPR you already have.

Now, if your car is not running right, chances are something is broken - you have a boost leak or what not. I am sure MRC will be more than happy to fix your car and charge you for it.

As for MAP sensor and Injectors - I have 3 bar, 4 bar MAP sensors and also used real RS2 injectors, none of this replica stuff. If you have any interest in buying those, PM me, and I am sure we can agree on a price.

PM sent mate defo interested, is thier any halm in puttin a 4bar map sensor in if you only need a 3bar?? (it it worth getting ona nd fitting it for later days when i get a gt30 or something)

[prj]

Since you are getting your car custom mapped there is absolutely no harm fitting a 4 bar MAP sensor and they are the same price.
I PM'd you as well.

As for tuners - For a custom remap I would definitely recommend MRC. Mihnea has a lot of experience and information on these cars. Worth waiting for.

I actually have all the gear to map these cars right next to me at the moment, to bad there is so much distance between us.
