you need to get your z some mods like intake/exhaust/pulley. You can't let the civic pull on you like that. I've taken na's before with my 00 SI. But after 100mph, the Z will pull on it. CIVIC GONNA be bragging tonight on how it pulled on a 300zx. ouch!!! ---Just to let you know also, I've pulled on NA Supra's as well with my Civic, ehehhehe
