I need help with my RS TURBO lump please!

 

what's the problem with it ?

 

Take two in the morning & two in the evening & see if that helps.

 

Hello everyone, I wondered if someone could give me a little bit of advice.
I had 5 months ago a gorgeous Xr2i lowered spaced wheels the usual. Then I decided to drop an RS Turbo lump in it.
I've done all the nitty gritty stuff changed the whole lot wiring loom, ecu engine mounts engine (der!) gearbox new intercooler, new rad everything.

Guess what the bastard wont run properly and I have no idea what it is. It revs upto around 3,000rpm then wont go any higher. I can build up the revs to like 4,000rpm but if i put my foot down it just coughs and splutters.

I've rebuilt the head using my old XR2i top which only had 47,000miles on it, made sure its timed correctly but still it wont rev up....hmmmm?

Any ideas?

cheers

 

fuel pump ??

 

More boost??

 

Nah i dont think so thats the only thing I didnt change, you might know different but I got told the XR2i and RS Turbo ones arent far different from each other.
cheers

 

Its not even boosting or getting on boost the turbo only kicks in at like 3,000rpm

 

can anyone give me any info?

 

Sounds like it's runnin outta fuel pal

 

Fuel or timing? My cossie did something similar a few months ago and it turned out to be a fucked fuel reg...

 

Check your fuel pressure and get on Bosch 044 pump.

 

ok cool, well ill try the fuel pump and/or reg but do any of you recon it could be the ecu???? cheers

 

Did you use the XR2i fuel rail & reg ??

I think the Fiesta's are in tank pumps arn't they ?? Change the fuel filter also for an rs turbo item.

r u sure that the filter would make all the difference?

 

No, not sayin that at all, but it won't help the situation !!

Main suspects will be the pump & fuel pressure regulator. Assuming your running the rs turbo injectors, ecu, map sensor etc ??

I'd defo say it's fuel related tho, going from your vague discription pal !!
