How much money do you want to spend, and how much power do you want?

im looking 150 mark at the wheels but use able not boy racer stage 4 tail pipe made from 8in dast bin with crome all round the engine

In that case budget for at least £3000 for an engine and box.......still interested?

ditch the n/a cam and fit a phase 2

chamber size depends on the C/R you disire with the pistons you choose!

aim around 8:1 0r 8.5:1 is the best compromise

yes no one can come into the turbo land on a small budget when you go into 150 mark

Right enough there.

To achieve 150bhp at the wheels you probably need approaching 180bhp odd at the flywheel.

For the gearbox to cope with this, you are looking at a full straight cut box, straight cut drops, and a cross pin diff at the very least.

Moving upwards, the standard crank will suffice, balanced as an assy with the flywheel and pulley. Then the rods, again standard will suffice, checked over, with ARP rod bolts. Pistons forged items with 15 or 18cc. Cylinder head, large chamber head with ports flowed, guide bosses reduced. Avonbar ph2 or 3 camshaft timed in with vernier pulley, roller rockers. Then a turboharger, a T3 may be best to produce this kind of top end power, maybe even with a different exhaust housing as well.

This list of parts is only a start. Everything will have to be in first class condition, and built carefully paying attention to all clearances and matching components. Simply bolting it together and hoping for the best will not produce the goods.

what power is safe on a std box ive got a 4 pin diff in the car on 3.1 crownwheel and pinion

about 96-98 at the flywheel lol

seriously do a search the side loadings of standard gears has been much discussed
