s5 turbo on 12a na engine
 

its my 12a turbo kit . three weeks of work. used what i could find in my garage and at my friends shop. a old wrx invidia exhaust reused the flanges and muffler using a borla xr-1 as a resonator. the turbo is a stock s5 not using the internel wastegate . the carb is a holley h.p. 390 boost prep with ported secondary maybe 410 cfm. metering blocks are weber power plates never used them be4....? so stay tune as i tune.......... i may reproduce 4 sale . for 12a lovers

Mad Skills Dude...Mad Skills!
:nod:

if anyone is having trouble finding exhaust manifolds for a turbo app. check out Moremazda's website Shookmotorsports.com. Reasonable and professional.

Looks great thou.

thanks...:lol::lol::lol::lol:

whats the wall thickness of the tubing you used for the manifold? looks great!

it 1/8 steam pipe fittings..............:noyes:

did you machine an s5 turbo flange? Could you explain how you did the wastegate a little more? Do the two runners collect at the "wastegate box" or do you somehow keep them seperate to preserve the divided design?

i used a plasme cutter and drill press to make the flange.yes the 2 runners collect at box.. and i ported the turbo little to get rid of flat parts ,.. i made a v inside

got some work done tonight Attachment 407501

Nice work man!!

Rene at RX3mist used to, or still may produce tubular manifolds that could incorporate the S4 or S5 turbo flange if you desired. His manifolds were quality pieces, and were going for $250-$300 when he was producing them. If you search on here, you should be able to find his phone number.

Secondly, search out FB II posts on here, he is one of the original Blow through Turbo 12a guys, and his posts should outline a lot of information for anyone who is curious about blow through...

thanks 4 the infoe.....:)
