Hello to everybody and Happy New Year.

Im thinking with a friend of mine to built a drag FD to beat the Evos , Celica GT4 , Deltonas , here in Athens . These are makes 0/400 = ( 10.9 - 11.5 sec ). I know its difficult to beat them because they have all , lower than 2 sec / 0-18 m ( 4x4 ) . My best until now is 12.3 ( 0-400 ) with (0-18 ) / 2.4 sec and 195 km exit , with street tires irell Pzero corsa dry . The FD produce 327 hp @ wheels and now we planning for 450 hp +.

Hey rotorheads please give me a help !!!!!!

Do you want this is a purely race-motor? Or your normal street car?

If you just want to occasionally blast it about, fill in the water jacket behind the ports, and extend it as far as you like. J-porting could also be an idea

talk to "Judge Ito" on the forums, he can build you a HUGE street port

Thats some precise porting. I'm Impressed. It's to bad I don't have clear picsas you do to do some comparisons.

I would like to built a full race engine but i'm afraid to fill in the water . Its a risk for me .
93blackfd . This is the max street potring that i can do before the water side ?

Please who can help me, with other pictures for huge street porting ?

that's the largest i've seen, unlses you want to get about 10hrs out of your motor before a rebuild, then you could go J-port

you'd have to drain the coolant before storing the motor...total PITA

Thank you very much 93blackfd.

Then go PP
