"I haven't done this conversion yet but for anyone looking to do it here is the "how to":

------------------------------------------------------------------------------------
· The 8 valve is a breeze to fit.
· All the 1.8 parts can be used including the
· viscous fan,
· all the bolt holes are there on the block for everything,
· including the 1.8 dizzy drive (bolt holes on the cam cover)
· Sump,
· exhaust,
· g/box in fact everything is a straight bolt on.
Fiddley bits......
· Water hoses, it is possible to cobble together the existing water hoses to fit the SEH using the two small carb pipes to go to the SEH throttle housing by using a straight connector and some extra hose.
· Other fiddly bit was a mounting bracket for the air flow meter. (email sales@cutomsolutions.me.uk ) he can supply a suitable custom made mounting bracket at a ridiculous (cheap) price
· The worst fiddly bit was extending the loom so the ECU fits in the drivers footwell.
· The loom is very simple too.
it is all self contained and like me you will have to fit high pressure fuel lines (I used rubber items for ease of fitting and the fact they won't rust with something stupid like 100 BAR burst pressure)
· Make sure the Hones are bored if fitting new rings
· Also you will need an injection tank, not a problem to source one of these for the coupe, max price £15 is what I would expect to pay and of course you will have to fit a fuel pump, again not too much of a problem
· Clutch...... I used a 1990 2.0i Carlton clutch pressure plate and release bearing.
· Bolt on your 2.0i ohc Carlton Clutch,
· your 1.8 box,
· your 1.8 dizzy drive and timing cover,
· swap the sumps over,
· bolt on your 1.8 engine mounts,
· OH I think you need to swap the oil pick up pipes too.
If you want to retain the viscous coupled fan, there are bolt holes on the Sri Block for this too.
· Cobble up your water hoses,
· wire it up,
· bolt it in
· and start it up.
Nothing to it........
·
· Also had some head work done on my engine
· For a cheap and very simple conversion you cannot get better. I was talking to Chris Cotteril at the AGM on Sunday he told me he was getting 160 bhp from his old 8 valve SEH.
· Of all the jobs, I think I hated fitting the fuel lines the most.
And trying to solder the wires on the extended loom on a windy day (soldering iron didn't keep hot enough)
· Don't let the fact that the sri 130 is a FWD car enter into your head.
· Basically all you are doing is turning the sri engine round 90 degrees to mate up with the 1.8 Manta gearbox.
· "EVERYTHING" off of the 1.8 will bolt onto the 130 engine
But you may find the SRi 130 alternator to be a tad higher in the amps output department than your 1.8
· . On the SRi engine you will find 3 (i think) engine mounts (throw theses away) and a load of water pipes bolted onto the block, throw these out of harms way but hang on to them in case you want to cobble some pipes up later.
· dont forget to fit a spiggot bearing into the end of the crank or youll knacker your imput shaft on the gearbox

What made the SRi 130 quicker than a standard SRi?
· 2 Bhp more than Astra GTE 2.0L due to better exhaust route
· Revised Bosch Motronic Engine Management
· Larger Intake valves & exhaust manifold
· More compact combustion chamber shape
· Bigger bore exhaust along the length
· Shorter, lighter Pistons
· Revised valve timing
· Integrated, adaptive engine management & ignition system
· Engine block both stiffer & lighter
· Crank & con rods lightened
· Friction loss cut by thinner piston rings & valve stems
· New high efficiency oil pump & cooler in front grille.
· Smaller water jacket for quicker warm up & enhanced pump.
Standard: 130Bhp @ 5600 &133lb ft @ 4600 rpm 0-60 circa 8s
