Engine Swap Xflow to ST170 and 4 speed to 5 speed box
I've had a lot of interest on my engine swap Xflow to ST170 Duratec or {Black top Zetec} with a Duratec badge on it
And 4 speed to type 9 5 speed box at the same time.
So thought Id have a go at a blog to assist owners with the process and put any info in one place
A quick over view is
ST170 Duratec is for the ordering of parts a Black top Zetec {carbs on the off side}
Engine fits on to a type 9 gearbox with a flywheel from 1800 Zetec modded to take a cable clutch {retro ford}
Alternator fits with retro ford brackets which allow the water pump to turn in the right direction
Sump ERA, carbs ZX6R, manifolds, ECU from Chester Sports Cars who have been very very helpful and put a carb ECU almost full conversion kit of bits together for me
Engine mounts from a GBS zero {cut and dropped 1/2"} low pressure fuel pump and exhaust flange from GBS [i cut the flange off the old stainless Xflow downpipes then cut wedges from the bottom of the pipes to allow them to bend and line up with new flange]
Standard water rail and pinto bell housing
Prop shaft still fits ok
Radiator hoses from eBay
Its taken 3 weeks over Christmas to swap so quite quick about 42 hours put in build time. Still waiting for exhaust to come back from TIG welders and then off to rolling road :t-up:
These are my experiences of swapping the engine and I'm a trained aircraft fitter but not a car mechanic so normal disclaimer!!!!!
Gear lever needs moving back with a adaptor from Rally Design

Been in garage again
Down pipes fitted
Gear lever moved back
TPS on carbs wired in
Computer pluged in to set up TBS
Engine run up cooling fan working
Slight weeps to sort on cooling
Waiting for snow to melt so I can take it for a run, then off to rolling road
Snow melted so off for a run today, car went well warmed up quick, it went very quick after the crossflow too
Still to cold and icy for a full test but 60 miles with no leeks or bits dropping off
Need to book a rolling road setup now and see what it puts out {what ever it is its enough for me on the road }
I've added a link to photo bucket that gives you access to photos of the progress so far, any further questions and photos you my like to help with your builds please just ask

Just home from rolling road see video clip
It all went well putting out 132BHP @ 6500 RPM at the rear wheels.
The factory redline is at 7200 RPM with the limiter set at 7350 RPM my BHP was going up at the rate of 7 BHP per 500 RPM so we could have got a higher final reading on paper by increassing my over safe 6500 RPM limit
This is still nowhere near Fords claimed 170 BHP but dont let this put you off this engine. The proof of the pudding is in the driving and its plenty on options for power upgrades if you want
Its looking like the carbs have had a Dyno jet kit fitted so I need standard needles and the header pipes might need to be made out of larger diameter pipes to release a few more horses, if I want more out of it
I have reduced the solenoid valve from 3000RPM to 1500RPM and its a completely different car
It now pulls very evenly with no flat spot at 2800RPM right through and is a much easier car to drive on the road
Then I can always put cams and gas flow heads if I need more
So I still have lots of scope for further upgrades
