Hi I've been recently looking into getting a turbo timer and boost gauge and came across heads up displays which had both. However the two that had the turbo timer feature are discontinued the mach V HUD and the defi. I have found a TS Performance HUD but it doesn't have a turbo timer and is almost twice the price of the discontinued ones. Does anybody know of anybody who makes these anymore? Or an old one for sale? I have seen corvette, pontiac, and bmw HUD's on ebay is it possible to make one of these work one the s4 they are pretty bulky? Or any DIY on the subject?

 

i wanted one of the defi huds' a cou[le years ago but could never find one. they were much more popular in the japanese car market. check out zilvia.net or hondatech. it requires the use of the defi link as well.

have you checked out the lower temp switch? its what s4 guys use instead of turbo timers.
