here is a little snip of some first start footage of something i have been doing for a mate





13b 6 port turbo LPG b2000

( yes that is an exhaust,, and a vac leak you can hear ! )



i have done all the engine build and conversion, only farmed out the gas fit and the rear section of the exhaust



its a 13b "RESI" franken engine

,, using an unusual combination of end plates with some porting , fitted with a s4 turbo,,

all in an aussie mazda b2000 ute

the conversion is using rx7 s1 front plate attached to inverted s4 rx7 spark-side metal brackets welded to the frame

the gearbox ( s5t ) has the shifter relocated 103mm forwards , and there is a heavy duty custom 2 piece tailshaft



this ute engine is a RESI 6 port ( mild aux ) ,, tall port extended primary ,, with rx4 rotors



the LPG system is custom plenum, VN TB, impco 225 and model E converter



ignition is bosch bim 024 ( x 2 ) and bosch HEC 716 ( x 2 ) , dual leading igniter direct fire ignition system timed from a modded 12at dizzy

( leading only, no trail spark by intention,, though i have mounted that coil and wired it up )

the turbo will be s4 highflow after run in

( actually its going on as soon as the handbuilt inlet gasket is done )



the intercooler is a supra/ chaser in guard item,, mounted,, in the guard
