actually the best race combo is a 5efhe/4efte hybrid. my bud in orlando is running 450whp and his best time was in the 11's. the 4efte is a great motor, but than again it's just a 1.3l. as for the 5efe and the 5efhe are 1.5l. The 5efe is good for about 10psi safely. as for the 5efhe is good for about 22 safely(believe me i know

) but yeah good luck with it, and also did you get the second runners to kick in w/o the ecu?
