i have a 57 trim ct26 on the car currently. with a lil more tuning id bet money im ~400rwhp or higher and thats wit hthe stock pos mk3 i/c. cant wait to get my new intake manifold and fmic on. later ill instal my gt40 but need to buy alot more stuff first. stock internals have been known to hold over 600rwhp. that wont happen without a standalone and a good tune. also needs a mhg and arp head studs.
