If there ever was a definition of “ghetto backyard tuning” this would be it. Brazing over a BBQ flame? Punching big holes by drilling lots of little ones? Venting A/C coolant to the atmosphere? It’s all here in this insane thread as “Spudchucker” goes on a mission to supercharge his 2.5 N/A Impreza. Click “Read more” to see all the gorey pictures, or click here to see the thread on RS25.

A couple months ago I saw the reddevil and Skidd build threads (congrats on the recent success Skidd!) and after sleeping on it that night, I couldn’t think about anything other than how I was gonna do my car next I was gonna go with a Raptor system, but after learning they weren’t ready for my model year, I decided to just make one myself.

Eric Hsu at Beyond The Dyno shares this Specialty-Z built 300ZX Twin Turbo build on his website with a few thoughts of his own. This 300ZX is a monster, with twin GT3071 turbochargers, a wealth of supporting parts, and a good tune. The results are well over 1000HP at the wheels, a true sleeper because from the outside, it looks almost stock. Click here for the full description!

I’d love to have a Z32 one of these days. I still have fond memories of the Z32 even though I haven’t driven one in a long while. Back in the day when I was 20 (circa 1993), Jeff the Tokyo Pimp and I did several Z32 NA and TTs with 150 shots of direct port nitrous. Those were my first experiences with involuntary lane changes and smoking tires at 80mph.

I stumbled on to WarmAndSCSI’s turbo V6 Galant build thread. Interesting stuff, along with pictures of transmission carnage and dyno sheets, along with lots of buildup pictures.

earlmred over at the NewTiburon forums just shoved a turbocharger into his V6 Tiburon. It’s a clean looking install, but it has yet to be tuned. Check out the pictures and a NSFW video here by clicking “Read More” or click here to see the thread!

Installed the turbo this weekend, had a BIG problem driving it home, the AEM oil pressure sending unit blew out and had a huge loss of oil pressure … luckily found a 24 hour shop and we capped that ***** off and went on my way after changing the oil (since I dumped in a gallon of junk conventional to get it to a hotel). Anyways, running 5 psi for the moment, until I get AEM to replace or have to buy a new $170 sending unit, AFR is a safeish 10 to just under 12, running well so far. First and second are completely useless at WOT, just spins tire once boost hits, and chirps through half of third! Oh yeah, we did junk the BOV that came with Duffer’s kit and replaced with a Vortec unit my buddy had laying around … the BOV that came with the kit is teeny tiny.
