Graeme Posted November 3, 2002 Share Posted November 3, 2002 Hey guys , I have a L28 N54 block and P90 head and want to get 250 hp N/A? Is this possible with $2000- $3000 Im currently running triple 40mm dellorto's and standard compression, and am ready to rebuild her.

Guest Ian turbo240 Posted November 3, 2002 Share Posted November 3, 2002 I'm afraid it's not gonna happen on that budget. You would need to spend $2k-$3k on the cylinder head alone to make that much power N/A. Also, the 40mm carbs you have are too small. You would have to upgrade to minimum of 45mm. Within your budget, you should be able to easily achieve about 200hp, though. Use some stock L28 flat-top pistons and an N42 head and good cam and you should be there. Good luck!!!
