What's the Ultimate CRX HF engine Mod?
 

Recently, I've been looking at websites such as "3Tech Performance", which offer fuel economy engine modifications for the Geo Metro XFI. A few of the products that they offer are camshafts in economy grinds, along with economy heads that are ported & polished just to name a few. In addition to that, I've also been looking at the post on "Team Swift" and have noticed that 3Tech has some very happy customers.

That's when the thought occurred to me...."Is there a website that's just as devoted to offering the same FE modfications for CRX HF owners"? If not, than I would be just as curious to know, what the ULTIMATE HF engine modification for increasing FE would be.

Thank You.

A D15Z1 is the Ultimate CRX Hf mod. ;)

Thank You.


I'd say high 40's driven normally. 60 is very achievable on the highway. It should cost less than $2k to have it done including motor, new clutch and ecu swap. Where are you located? Maybe I could be of assistance.
