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 The oil pressure regulator has also been replaced by a 110psi race regulator , a thermal bypass pillet has been installed and oil jet mods done too.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.

A few more .....
 

A couple more .....

Ummmm..... KICK ASS!!!

Not much else to say, but I'll be the first to say, job well done. I await #'s

A couple more ...

Last one for now ...
 

All I have left to do is get my custom 3.5" exhaust system installed , and begin the break in.

Kind words , thank you ........., It became difficult at times , as I do all my work myself , but I was kept motiveted by all you forum members out there , thanks to you all. I will be sure to post numbers and give a full discription on the performance of the turbos and the motor .


PS ... these puppies spin while I'm cranking the motor !!!

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?:D

Jim

nice. I like all the custom work you got there.

Dayem, it's been a long wait...good luck!

what size - an fitting did you use for the oil feed return line?

My old set up was great , but I think it was more suited to drag , being a street car , I think I,d have a better overall performer with the twins.And to answer your last question , there's no money tree here !! , fortunately I have a job that pays well and requires a lot of overtime.

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.

:eek: very nice.

That is nuts, please get a dyno chart ASAP, awesome work, I really acknowledge your hard work there, where did that intake manifold come from?

great work, its nice to see people putting that much effort into building custom setups on their own.

Didn't you used to have a GT42R setup?

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

Appears to be a Jaytech but i could be wrong... :confused:

hows the power band on the twins

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.

double post

Dont know yet , the motor starts and everything , but I'm still to get my custom 3.5 " ( scavanged from a JDM Supra) exhayst system installed , After I'm done this I'll have to break in .. Then its time for boost !!.

so when is it going to hit the dyno?

In about three weeks .

congrats and good luck w your setup.
