But I have had the sheer pleasure of driving Brian's car. It is a rocket.

I had the pleasure of going Back To the Future while Mick was driving it too. DAMN that car is quick. The car is truely a credit to Brian. Can't wait to see what else he has up his sleeve.

You can read more about my car in Zoom, No. 77, page 53, just out.

I'll see if I can get some of the photos, such as rods & pistons etc, and post them here.

Here's a pic of the new rod compared to the old rod.

Here's a pic of the new rod compared to the old rod.

Wow Brian, that's a big difference. Who makes the new rod and out of what? What would a set of rods like that cost. How much would it cost to fit them and what else would you change at the same time while the engine is pulled down?

Geea.

Geea,

Yes, substantially larger and stronger.

You'd have to ask Simon at Nizpro for more details, including cost.

These are used as part of the Nizpro stage 3 kit, and this is recommended by them for 330rwkw+ engines. I did valve springs, rods and pistons at the same time, helping to reduce costs and give me more future power upgrade potential.

I received some photos of my car as used in the zoom mag, and have approval to publish them.

Pistons are forged and substantially lighter than stock.

The forged H-beam rods and pistons have been balanced.

Compression ratio has been reduced from 8.7 to 8.3:1.

I still get great throttle response because of the much more efficent inlet to the motor via all the factory plumbing that's removed, and can still run higher boost if I want.

Here's my block on the boring machine.

The block was well prepared: sonic, pressure and crack tested, strainer plate-honed bores, line-bored crack tunnel and the decks squared to the bores.

Standard crank has retained, but it was crack tested.

Head was not touched, except to machine the valve spring seats to accomodate the longer heavier-duty springs.

Hi Brian

I remember you saying that you changed the big ends and mains, and that they were in pretty bad shape , do you have any pics of these?

Cheers

Yes Frank, there were problems with the big-end bearings, such that it was predicted the stock motor would have had problems by 100k.

I'd advise anyone after big power to have their engine block examined. If my engine block is any way representative, there may well be quite a few failures in the future. I think this was discussed in your thread about potential problems a couple of months ago.

Sorry, I didn't receive or take any pics of these.
