Hi,
Ive spoken to D&A Fiat breakers, they gave my a queote for a 1108 engine as £175 +vat. I thgouht the 1242 was that price..?
Im going to stick with the 1108 engine, I think that 100hp/litre can easily be acheived. I am planing to lower th compression ratio slightly (CR top secret) to allow around 0.8bar turbo pressure, with multi layed copper spacer plate. The port will be slightly enlarged and polished out. The Valves will be re-profiled. The combustion chambers will be smoothed and polished out.
The piston crowns may be coated in Ceramic heat insulation - this is quite expensive...
I am yet to find a camshaft that has the right characteristics, but I have some cams from AUTOSPRINT engine, Birmingham - they do the Twin Cam Fiat engine, not sure about the f.i.r.e, will enquire.
The Intake charge will be intercooled (only if I can fit my intercooler in the bumper)
I had also thought of water injection to help prevent pinking & this improves intercooling as evapourative cooling. I have been speaking to company that does small cooling jets very cheaply in moulded plastic, but require 3bar (around fuel injection pressure) water pressure to atomise correctly and deliver 40cc/min, perfect for 5000rpm+ cooling.
I will have an oil cooler as well fitted to help the engine temp ( seems to go high in the std 500 anyway..)
The intake manifold will be slightly enlarged and polished and Matched to the head ports. The throttle body will be from the 1242 - as it is slightly larger in size.
I will be keeping lots of pic on my website (If I rem to put them on.)
It might sound OTT, but If youve got an engine on a stand, you can take all the time in thenworld - no rush.. Im looking forward to it..
Youcan see the spec of my last engine on my website - it was sold to a guy who was putting it into his Escort RS2000 Track Car, and was very pleased.
I'll keep you'all posted, and pics will(hopfuly be appearing on my website)
