Re: 1.3 mods

howdy,

here's what i did. weber carb 42 46 jetted, elec. fan, under pulley, bored 40 over, tracker exhaust vavles in sammi head, traker intake on sammi head, high compression piston tops, gti crankshaft, dt header, 2.25" exhaust, msd igntioin, accel spark plug wires, ngk v-groove plugs, obx intake for a honda, 3 row radiator, gm alt, hawk torqueor cam, adjustable cam sporket, timing advanced 3 degrees, holley fuel pressure regulator, holley low pressure fuel pump, only runs 87 octane, v8 cat, hardcore offroad muffler, fuel cooler, glass fuel filter, brass rotor cap knobs, brass rotor button, accel coil, and some other things but i can't remember all of them. i had the engine dyno ayt cincy speed shop. hp = 107 torque = 78lbs. i would say that i have around $4000, but that with the some swift engine parts still sitting in the garage. i blue printed the engine and don's crankshaft did the balancing, boring, honing, porting, lapping, and a whole bunch of good ideas. like making allen headed screw to replace all of those stupid head phillips screws. he also cut and fitted my tracker intake to fit it to the sammi head and then reported the sammi head intake ports to flow as much fuel as the tracker intake.

Re: 1.3 mods

What did you gain with the GTI crankshaft? How does 2.25 exhaust mate to DT header collector? Is collector 2.25?

Re: 1.3 mods

howdy,
here's what i know

my 1.3L HP = 107 @ 5000 torque = 78 @ 3400
stock 1.6L HP = 80 @ 5500 torque = 94 @ 3000
stock 1.8L HP = 120 @ 6500 torque = 114 @ 3500
ok my rpms are different due to the cam sporket and hawk cam.

Re: 1.3 mods

howdy,
the GTI crank is alot more strong at high rpms. it also has larger oil jurnals. howdy if you look at the dt header you will notice that the collector they send you is sloped down to 2". so when i told the muffler guy told keep it tite on the frame. he asked if i would like him to make me a collector that would stay the same size as the header port. thus he made it straight for me and now i have no knock down in size.
