gude sux ***... a member had the gude head package and from what i remember.. it totally f**ked up his car... kms is the way to go if you wanna go all motor.. they have the individual throttle body system with direct port nitrous putting down 250 whp... i dunno if that daily driver but that's pretty damn respectable for an all motor civic with nitrous... actually.. i'm not sure if he ran the nitrous with that setup.... oh well.. correct me if i'm wrong people

Rep Power: 0 i calculated the compression ratio of the s2000 which has 11.7:1 if the civic had 11.7:1 with arias high compression pistons, wouldnt it make like 150ish hp on premium gas like the s2000? do the math:
9.9 / 127 = 11.7 / x
where x = about 150 - 5 hp because of SOHC
9.9 / 127 = 11.7 / x
where x = about 150 - 5 hp because of SOHC

on the otherhand, why is everyone only thinking jet ecu and such? why not get a completely new standalone? haltec of motech ems? plus, they cna be wired to a pc, a lot easier to do tuning than the jet one, where you'll have to send it back to get it tuned again. and the haltec e6k have standalone direct ignition control to tune the sparks even more. once you get up to that high compression, it won't just be the motor anymore, but also the timing

That would be more trouble than it's worth.

this does absolutely nothing.. wow vtec...
another thing... do you really think by sticking on a d17 vtec head, you'll go from sohc to dohc and gain considerable amounts of power??

I've learned in the fight for hp every little bit helps.

well maybe if you started with a ex thats 113 stock to the wheels
so a 15 horspower increas isnt all that much with all that stuff but
to the wheels is a diff story

i don't know, but i think the variable valve timing will definitly help a little, but then you have them hight compression stuff you gotta worry about. all this brain work, might as well get a turbo, or get a new car (locally, a rx-7 tt cost about 12k. could've traded your civic in for a tt rx7, instead of the 100,000 miles manual civic)

Rep Power: 0 I went to the Magnaflow factory since i live right by it and asked to see dyno results for our cars . They were cool about it and showed me there reports . The EX had 112 stock and 115 with a magnaflow exaust . So maybe the dyno results vary depending on condition but that what magnaflow showed me so .

Rep Power: 0 no its called drifiting its just how you enter the drift you can either
pull the ebrake and then put it down and continue to drift or if yer rear wheel drive you can use raw horespower but its still called drifting in japan as long as its controlled

don't think so...you'd have to rebuild the engine itself. I think sohc has the pistons lined up in a row, while the dohc has the pistons in groups of 2 with 2 in each. I'm not sure, so correct me if i'm wrong.

Rep Power: 0 Ok, I'm done being childish. hehe. I just sent an email to KMS asking about some sort of package for the D17. Maybe that will yield some decent information. I will keep you posted on their reply.

Rep Power: 0 so where can i get a d17 head to p/p so i dont need to wait for it to get done? i could have my other head as a spare. and where can i get a d17 thottle body to bore out 8 mm like spider883? now all i need is an unorthodox pulley kit, cam gear adv 3 deg, reground cam, 11:1 compression pistons and i could probably get 140 to the wheels if done all right.

or look around town, ask around for a machine shop
the place you live should have 1-2 if not more machine shops
