Miles's managed a 14.01 1/4, but that's a nova and stickign his engine in a corsa would see at least 0.5 secs added. If he had got a 40% plate diff in it and not a ATB then his time would have gone down more.
Carbs will give less power and worse fuel economcy next to TB's as you can't mapp every point in the rev and load range, and the fuel atomisation isn't as good.
with 2mm pockets in the pistons and 285deg 11mm lift cams you'd be in the 160BHP area on a 1.4

Did JR's even have throttle boddies??
I bet you can get 145 - 150 BHP out of the 1.4 put a LSD on it and your laughing!!
as matt said 136bhp, with tbs and higher profile cams i would have be looking at 155bhp

In my opinion thats the reason that'd win it over for me. You can rebuild engines, or change parts, but its not as good as a genuine low milage, well running engine IMO. Other thing to consider is resale value. You caould always put just the Tb's on, with the APR bolts, ECU and manifold, and leave it at that. When you come to sell it wont be too hard to reverse the process, and take them back off, and put the old stuff back on, bar the APR's. Pretty sure they'd still be worth a fair bit as there not really suceptable to wear like other parts. Thats something it's much harder/pointless to do on a valver  .

I had a set of TB's that from new had 80,000miles put one them. When I broke the engine, i sent them back to jenvey cause I was after new badges and mentioned the milage and they wanted to see the wear rates. They were with in tolerance for brand new ones, which shouts for the quailty of them.
On a resale note, DCOe parallels have better resale value than tapers as they can be bolted on any engine with a DCOE manifold bloted to it. Tapers dont.
And on milage, a freshly rebuilt mega mileage block is meant to be better, least that's what BMW engineers thought when it came to the 1.5turbo F1 engine, they sourced 200000mile old road blocks.

Thats wierd, i cant think what the benifits of using an older block would be... Saying that, i cant even see why the hell they'd use a road block for a race car engine  .
