To make the adaptor plate, I used the thin tin plate that goes in between the motor and gearbox of the standard starion motor as a template. I had this shape plasma cut into a piece of 8mm thick mild steel. I marked on the 8mm steel plate the bolt patten from the template. I drilled and tapped a 10mm x 1.25 mm thread in the holes.
Then I took the thin tin plate that goes between the engine and gearbox of the VR4 engine and VR4 gearbox (which I borrowed from Owen), lined up the two common holes that the templates from the two engines share, and then I used the VR4 thin tin plate as a template to mark the holes that need to bolt the adaptor plate on to the VR4 block.
Then all the holes were drilled and countersunk.
These are the two tin plates, VR4 is in front and the original Starion one in the back.
Awesome work Alan! We've all been very quiet from the southern end of Australia! My Starion is still sitting in my garage, she's been cold for a very long time, but its clean and protected which is most important! One day, when I have the cash!

Good smart thinking .Well done now we all know how to adapt a staz wide block box to a narrow block Evo motor :beer
I've had mine since 03 07 92

THE OLDER I GET THE FASTER I WAS
GROWING OLD IS MANDATORY GROWING UP IS OPTIONAL

OMG fiberglass
Megga weight reduction weight TBC
5 stud conversion with HUGE rotors
Cute little 12 inch sub with 700 Watt amp
Good effort , should of made a few of the adaptor plates , I fitted my cooler like that , when coolers that size cost over a grand . Should of seen the prices of turbos back then . Kinda showing my age .
Took the Starion to the dyno today.
Develops 280 HP ATW at 7000 RPM 20PSI boost
I am very pleased.
I don't have any dyno sheets but here is a photo of the gauge and a video of the run.
280hp atw on 20psi seems a little lowish compared to other 4gs,
just as an example my big16g pushed out 301hp at only 16psi and should hope to be up round the 330-340ish hp mark at 20psi when i sort my clutch out, not critiscising or anything just curious
nice figure anyway and will be plenty quick enough
Different dynos will give different results. Dynos are just a tuning tool anyway, its too easy to get caught up in the figures being to low when the important thing is how it performs on the track.
