100dollarZ Posted June 1, 2008 Share Posted June 1, 2008 Thought some of you might be interested. This is the car I was building before the Z. Bought it when I was 15 for 1800 bucks as a plane jane 350/350 z28 for 1800 bucks and turned it into this monster. Rebuilt the motor, slapped a turbo on it and put a 4 speed behind it. Sold it because I couldnt afford 5-6 MPG. . It was a baaaaaaaaaddass car though. I miss it so much. not many people were used to seeing a turbo carbureted SB at my car show... Specs: 355 8:1 compression 282 degree 114 LSA .480" cam JET stage 2 custom Qjet Mallory 685 digital box Martin Turbo setup 9psi relief valve Rajay 301E10 turbo 4 speed and a 3.42 peg leg rear end made it a smoke machine enjoy : ) Quote Link to comment Share on other sites More sharing options...

Pete84 Posted June 1, 2008 Share Posted June 1, 2008 Looks like a draw through setup - easier to tune? Looks great! Post more Quote Link to comment Share on other sites More sharing options...
100dollarZ Posted June 1, 2008 Author Share Posted June 1, 2008 heres some more pictures Pete- yes its a draw through setup. The Martin kit was very well designed compared to other draw-thoughs of the same vintage (early 80's). it uses a 2 piece intake manifold, the upper section recieves fuel, then goes to the turbo inlet, then is pressurized and then fed to the lower manifold. However, there are flapper valves on the bottom of the upper manifold that are open when there is no boost, so the air/fuel charge can bypass the turbo, making the motor run like a N/A. These valves close when boost is made (pretty much eliminating lag). There is no wastegate, so boost is controlled by a recirculation valve inside the manifold. You can see the flapper valves in this pic: and some more of the car: the engine I started with: Quote Link to comment Share on other sites More sharing options...
Six_Shooter Posted June 1, 2008 Share Posted June 1, 2008 A friend of mine has a Martin turbo set-up, has had it for years now, keeps saying he's going to use it, but hasn't yet. He said he'll likely install a small block in his malibu for a while (currently a BBC that needs some work), just to use this system. Looks good.
