Title: tips for turbo engine spec Post by: Rocket Ron on January 06, 2009, 09:52:14 am Hi all
Just picked up a CB turbo / efi cb set up and I'm looking for some help with the engine spec.. I would like to use a pair of the JPM heads as I've been impressed with the cars running these and they seem to have more cooling area than most performance heads, but I'm looking for some help with rods, timing gears, compression ratio, cam, turbo size etc . I have a 2276 with IDA's which was built for me in my bug and I'm real happy with. I'm told that this size of engine go together fairly easy, so I'm thinking of this sort of size engine again It will be going into the ghia I've got and this will be fulll street weight plus cage. The ghia got irs out back so I'm looking to run a uprated bus box. My goal would be to run a 11.99. What sort of hp and set up do I need for this. I think the problem is going to be lack of grip as I'm limited to the size of wheel I can get out back. Any tips or pointers for a turbo virgin ;D Title: Re: tips for turbo engine spec Post by: yvre on January 06, 2009, 10:08:25 am There you go:

Any tips or pointers for a turbo virgin ;D Ron ,look at what Mike lawless has done to his ghia regards fitting the slicks and a bus box here: http://home.comcast.net/~mlawless29/wkr.htm You would need to be looking at about 300hp to guarantee 11s,given the way turbo cars launch and you have to shift the thing.I have PM you some more ;) cheers richie Title: Re: tips for turbo engine spec Post by: Roman on January 06, 2009, 21:23:37 pm You don't need any turbo to run 11.99 with JPM heads!

With a full weight ghia with cage,bus box,IRS and driver weighing about 2400lbs? you think? ;) it should end up really drivable with sensible compression for english fuel and still run that with ease :) cheers richie Title: Re: tips for turbo engine spec Post by: Rocket Ron on January 06, 2009, 22:56:42 pm Hi all Just picked up a CB turbo / efi cb set up and I'm looking for some help with the engine spec..

If it is 2400 lbs I agree, you would need around 300 hp to get into the 11's with some margin.
