Hello!
I am about to recondition my Turbo Engine and I would like your suggestion on the engine specs befor ei place my order to MED. I am targeting to a road-weekend-smooth driven Mini of around 130bhp.
Please let me hav your opinion about parts that i may consider to upgrade in order to achive desired power and reliability OR degrade to save some costs.

- Capacity: 1293cc
- CR: 8.8:1
- Boost: 12psi
- Valves: In 35.6mm, Exh. 30mm. Stainless steel with MED road springs
- Valve Guides: MED std bronze
- Chamber:25cc
- Pistons: Omega Cast +20 10cc
- Dublex timing chain kit
- Camshaft: Avonbar Phase 2 (or suggest alternative Piper Road Camshaft from MED)
- Roller Rockers: 1.3 OR 1.5 ?
- Front Mounted Intercooler - size suggestions..?
- Cylinder Head Gasket: is the BK450 sufficient or should go more steel gasket?
- Crank/Clutch/Gearbox/Diff: All standard for the moment.

Thank you for your imput and advises!

George

Clutch will need uograding, look at an RTS. And I'd suggest a cross pin diff in the box.

Rockers wise, most people just use standard. You can fit the 1.3's if you've got the money. And people who have used 1.5's with the phase 2 cam say its too "peaky"
Intercooler, go for the biggest one you can fit!
