On a dynojet you could get more power than that. Personally I'd probably use an SMSP header instead, but the Toda is nice (Hytech also). Also, I'd suggest some decent cam gears to adjust overlap. I'd also suggest against the Exedy, results vary but a lot of them tend to fail (the exedy whores will say it's installer error, even though some of those exedy whores had some fail :shrug: )
