Works well on the aerial atom Honda engines and Jeffw has one on his 400hp zetec Phoenix. Will need an inter cooler which may be interesting to mount in a libra and get good airflow over it. Bigger injectors may also be needed with a mappable ecu.

Indeed, I have it all planned in my head I just need a basic kit or even the blower on its own...hopefully not costing the earth as the rest will be custom anyway

B18C6 type R, but plan to fit lower compression pistons and H beam rods. It's all be done before and the kits utilise a C30-94, but the kits are no use to me as it simply won't fit where it would normally on an integra/civic. Sounds like some of the slightly smaller C30 units would still be adequate, I just wanted to put the feelers out...

Rods I can understand but I doubt you want to run lower compression pistons. Mine runs 10.5:1 and the TTS Honda kits don't change the pistons as far as I'm aware. The C30 units are all the same size and you would really need the 94 not the smaller ones.

Hi Jeff

Cheers will keep a lookout for a 94 then. I was only going to drop it to 10:1 from 11:1. From what I've read a standard B18C6 is somewhat limited to around 300 with its original 11:1 comp ratio. I think the K20 has lower dynamic compression in vtec so it's a little more forgiving.

That mount is nice but not really any use to me. I'm going to have to make my own plate and fit it above the alternator similar to how the Jackson kits are driven, there's no space anywhere else. Another reason for having to make my own plate is I'll have to design my own tensioner arrangement so the charger runs off the back of the belt... as my engine runs anti clockwise.

Do you run a C30-94 or a C38?

C30-94

A lot of the TTS Honda kits (F20C etc) run the C38.
