Ok my name is lonne and i have a 2007 h3 hummer with a 3.7l engine.

well it belongs to my wife.

So my wife has been complaining about how underpowered her hummer is and
so i opened my mouth and told her ill just install a turbo. I have the turbo installed but I can not find any info on what injector size i need or where to have the pcm tuned. Can someone help before my wife hurts me.LOL

 

Hello and welcome to HF.

As this section indicates, this area is NOT for technical questions, post your question in the H3 section, it will get a lot more attention.


Rather than a turbo for an I5, I would have just showed my wife how to drive a 5000# FT AWD truck and done the usual mod package. The I5 is not under powered, it just does not function like a V6 car or Mini Van/SUV.

HUGE on low end TQ, long on the HP wind out. Its a straight block, that IS how they work.

 

With a turbo that motor is not long for this planet unless you totally rebuilt the bottom end.

Should live with it or sell and buy an Alpha if she wants more...
