  • how come the vxr doesnt map as well as VAG?

    as i still keep in touch with my old vw forum i have been reading up on how the newer vag range seem to map much better than vaux, for stage one revo and zorst you can push 320 bhp but they start with the same power as the vxr just about, random eh? guess the german engines are better

        Am sure the next generation GM 2L engine is out in the states and pushing 260ish std.

        Just a case I think that the VXR engine is a generation behind the TFSI unit and a better turbo on the VAG cars

            If it gets that engine then yup I guess so - lets hope the credit crunch doesn't hamper cars into being sensible

              The main problems with vauxhalls are the tiny turbo, restrictive exhaust (esp. the precat) and mediocre intercooler (especially the positioning of the VXR one).

              Get these sorted and it turns it into quite an animal!
              Sold - Arden Blue Astra VXR on 19's
              Ordered - Pure White Golf GTI on 18's (couldn't stomach paying for 19" tyres any more!)

                  I agree.

                  I drove a Leon Cupra the other day - 313bhp and 340lbft with just a remap and ITG filter




                  Edition 30 For me next i think

                    Also direct injection helps give better/cleaner burn which reduces knock etc They are also able to use higher compression ratio's siimular to N/A engines. As Zlet's already said; the new SIDI GM engine that is going into the Insignia (I believe) is simular technology

                      well i had a golf gti mk5 for a hire car while my vxr was in the body shop and i had that for 5 weeks and i didn't rate it at all i found it unresponsive and full of lag the only thing i didn't think that was that bad was the handling. But all i can say is thank god i got my vxr back!!

                        Why bother with the new, spend enough and you could get the old 2.2 up to 1400bhp, if you really wanted to

                        As flinty said the SIDI engine (Z20LNF) will hopefully come across, especially for maintaining performance whilst hitting emissions/econony - makes so much sense

                          That's the one (Couldn't remember the name for the life of me!)

                          Trust Alex to know the engine code

                              I think the engine code for the Insignia SIDI 2.0T is A20NHT, the LNF is the Pontiac Solstice GXP variant.
                              Will bring Vauxhall back on par with VAG technology now
