My 1.4K project
Ok, so I've had a well tuned K for a good few years and I've pretty much reached the limit of what can be done (252bhp/170lbft) - well perhaps there's a bit more to come if I can be bothered but the hassle and expense will be high and the gains very small!!
Earlier this year an opportunity presented itself: to buy a 1.4K with some nice internals to make it suitable for turbo charging: steel crank, rods, non-stretch head bolts, cnc'd oil ladder, tame cams, head porting with more emphasis on the exhaust ports, and equal sized inlet and exhaust valves.
It's allegadly made 330bhp and 250lbft (or thereabouts) on an dyno already and was then sealed and stored.
A friend liberated it from the previous owners with the intention of fitting to his MGB GT (he runs Frontline for any MG buffs reading) but didn't need the 1.4k as I helped him fix his Rotrexed DVA 1.8k that suffered HGF due to running too high a CR. So he sold the engine on to me 
Rather than just use the turbo that came with it I decided I'd follow in ronin's footsteps and use an M62 supercharger as well! that shoudl get around the usual issues of a small engine and big (ish) turbo.
Stu Boffey and his brother (Ian Boffey who runs Clockwise Motion) fitted an M62 to Stu's Elise about 10 years ago, prior to Stu going to Rice power. Stu still had all the parts so I persuaded him to part with them.
First stage of the project is almost complete - getting the turbo manifold made.
Steve Guglielmi (of Guglielmi MotorSport in Daventry) is expertly advising on the project and is doing the clever installation work (and ensuring that I use no Dexion in the install!).
Steve put me in touch with Neil from Thermallogic to get the manifold made. Neil has done most of the manifolds used in the high power Time Attack cars, Subaru WRC and Focus WRC manifolds so knows how to make a decent manifold that will work well in a turbo car.
Steve sorted out the bulkhead mods required to fit the turbo behind the engine (big hole) and will sort the heatshielding required and the new bulkhead once he gets the car back:
The external wastegate is being fitted to the pipe on the far right, and I don't have a shot of the downpipe yet.
Next jobs are to bolt the supercharger on and get the charge cooler fitted. Steve is fitting the same type used on the 617bhp Audi Turbo Elise he uses in Time Attack. Then all the plumbing, pipework, etc. needs tackling.
Meanwhile Dave (DVAPower) Andrews will be taking a look at the head to see what can be done to improve the flow, double check all the head components are in good condition, change valve springs as a precaution and get the cam profiles measured so we know what we're dealing with. He is also going to help me remove the oil ladder as that doesn't want to come away from the crank ladder. Then the bottom end can be properly measured and checked and finally balanced (by Steve Smith at Vibration Free) with my uprated clutch and the crank pulley required to drive the supercharger.
More news and pics when I have something worth posting!
What power and torque am I after....?? As much as possible of course! But I'd like to think over 300bhp/200lbft is possible and perhaps closer to 400bhp/250lbft if I can get enough boost pressure at a low enough temp, and get the thing to rev properly. Boost modulation is planned with an external wastgate that should let the engine rev to over 8000 and make some decent power.
Using a standard PG1 but with the straight cut UCR Quaife ratios, and will change the bearings that are known to be weak. I'm staying with the standard casing for competition regulations, and the PG1 is a bit lighter than my 6 speed
