Hi lm wanting to know if anyone out there can help out with this one l have a yb turbo running a t34 with a custom manifold 3inch straight through big plenium bosch green injectors part number
0280 155 968 and a motec m84 ecu has 2.1bar boost and got it tuned and got 327 rwhp just wondering what else is out there for these to make 400 rwhp

cheers

 

I think at this point your limit is going to be the green injectors.

If the motec m84 can run high impedance injectors you're better off going for modern Bosch EV14 injectors (600cc maybe? - a retailer will be able to help you here!)

IF it cant Greys / Light Blues / Black Siemens injectors (Im not too clued up on these and their power, i think greys will do 380bhp, blues 400-420? Have a search on here - again though i would much prefer modern EV14's over any of these more old school injectors)

Once that's done your next limit is the hot side of your turbo, whether its a 0.48, 0.55 or 0.64. Generally from whats on here a 0.64 will see a genuine 380bhp.

Past 380bhp you'll want to start looking at a bigger turbo, GT30 etc etc

 

You mean 1.2 bar.

It's always said that 380 is a lot easier and something your current setup could achieve, barring the injectors.

From the Bosch range, you would need 403 "greys" and a calibration to suit, although be discerning over this, as a lot did/do not map these correctly, thus you can end up with bore wash.

i'd suggest upgrading your injectors along with your fuel pump.

but more importantly, upgrade your turbo, the T34 isn't a big hp turbo.

also, what intercooler are you using?
you'd need something large and free flowing for high boost.
