Some pics of my custom twins
Well , after almost a year of hard work , I'm finally at the finish line . Pictured is my set up which features (I'm sure you all know by now) , twin garrett GT3071R turbos blowing into a large NPR FMIC , custom ceramic coated exhaust manifold , pro jay intake , a very Capable fuel system (Sumped fuel tank , twin Bosch '044 pumps , -10 AN feed lines , 4 X 1600 cc Bosch secondaries and 550 primaries and a Paxton FPR) .
Spark is handled by four T11 trailing coils , one per plug , magnecor 10.5 mm wires ,a pair of MSD 6A's on the leading plugs , and a MSD Dis 2 on the trailing coils .
The motor has been done up with 1.25" peripheral ports , and a VERY generous opening of the other ports, all side ports have also been opened up to match those of the Cosmo's .Internally the motor has been race clearenced and I used new 2 piece Mazda seals . The oil pressure regulator has also been replaced by a 110psi race regulator , a thermal bypass pillet has been installed and oil jet mods done too.
Boost control is done via a pair of Tial 35mm wastegates and venting by means of a Tial BOV (I'm soon to add a second ) . The clutch is an OS Giken twin disc ,and the diff a new T11 clutch type . I also put in custom Diff and tranny braces .
Everything is controlled by an Autronic SM2 , doing everything from boost control (by gear) , to traction control , antilag , intercooler spray and direct water injection control.

Banned. I got OWNED!!!
WHOA, I'm impressed! I liked your old setup, I thought that would have been enough power! Are you into drag? Also, do you have a money tree in your back yard?

The fittings are -3 AN , the turbos came with a restrictor already installed and they had a -3AN male end , so I stayed with hat size.
very nice.

PS. I bought your custom red intake manifold with the extra injector rail in it.

I used to have a TA 45 / 51 with a half bridged motor , after I popped all three seals on the front rotor , because of a very DUMB error made by my tuner (hence the reason for me goin the extra mile to get a computer that does TRUE self/auto tune , the Autronic is REALLY an Amaizing system !), I decided to not just rebuild , but to redo everything .
The intake IS Pro Jay , its a semi -pp manifold and a holley styled 1250+ cfm tb and their intake plenum.
