there is no kit out there. however if you search you will see travis did make a turbo trailblazer a few years ago. mind you this is a complete one off. everything is custom


now I don't remember but did the 2005 come with the P10 or P12 PCM? Maybe scarab will chime in and shed a little more light on this for you

05- = P10 PCM so boost unfriendly.
06+ = P12 PCM/E67 ECM so boost friendly.

Some late 05s have the 06 motor, have to pop the hood and look at the PCM, if it has 3 same sized connectors then its a P10, if they're different sized its a P12.

ECM issues aside there is a turbo manifold available from steedspeed. The rest is plumbing - got a sawsall and a MIG welder - 2 weekends and your plumbed.

I'm trying to understand this a little better. Is your concern with the P10 not being friendly with a 2 or 3 bar MAP? Granted, if you can just use larger injectors and extending the MAP tables is a better way for boost, however, it isn't totally necessary. The Vortech setup I had on my S10 used an auxillary pump and FMU to add the additional fuel via higher pressure. I've also driven other turbocharged S10s and S10 blazers with this same setup the proved to be quite effective. The older computers like in my '98 weren't as friendly with boost as the 2001 and up models with the newer style PCM using a speed density setup and MAP sensors, which still isn't as good of an option as the Gen 7 DFI I'm currently using.

Anyway, I'm just wanting to better understand what the issues are with the P10.
