Is it possible to convert a Si into a Vtec.

exactly..
option 2 would be to buy ur mate with the vti-r civic, an integgy, and then race him.. i'm sure u can win the first 2 gears again :)

to answer your Question - NO you cant get a VTEC head for the ZC DOHC.

if you like the car and dont have much cash and just want to whip an integra every now and then, get a 60HP shot of NOS.. your std engine should be able to take it OK as long as you dont spray every day !!

Otherwise save your $$ for a B16A2.. even a B18B ( LS integra ) would be fun for your car..

dont bother turboing your ZC.. cheaper to go B16A2

for now though, rip-out your air-box and resonator and replace with a K&N style cone filter on the end of your Std intake tube and you might have more chance through 3rd.. intake before exhaust for power gains..

I'm following you with your posts VTEChnique!!

Firstly, its a D16A8, not a ZC (they are equivalent!)

B16 won't beat B18C powered integra. If you want to win, go for the B18C in the civic.

OR

Turbo your si for good power that will chew up any NA B18C vti-r and give you buckets more torque to play with :) 5psi will do the trick without destroying your box/engine :)

/me pats wynode on the head.. good advice.

and that should be written in stone. Only about 15bhp difference (VTiR 'teg), but a B18 will always pull away from a 16 :(

Other than that ROTFL @ this thread - I love the something for nothing "bolt on VTEC threads :P

Umm what car do you drive to not be able to beat a Vti-r????

Is it a civic sedan or hatchback with the d16a8????

Because i have an ed9 crx with extractors, exhaust, k&n pod filter and run optimax and have beaten teg vti-rs to third gear.

must be because civic's are HEAVY mwhahaha. :lol:

I drive an EF9 - that's a factory 160bhp B16A powered '90 Civic. The difference is, I don't BS my power figures or my times and I know that given a competant driver in both cars, the VTiR 'teg will pull away every time in the end.

I run to 100km/h in second and at that point the teg has shifted to 3rd and is starting to pull away.

Keep telling us your "kill" stories though, I find them vagually amusing and will be happy to run you at the strip in my unmodified "heavy" car.

This is 1/4 mile mind you - there's a bit more than 3rd gear involved and Slave will attest to me out-gunning a mildly modified non-VTEC CRX completely - and me with 70 odd kilos of passenger in the SiR :)

Just remember - racing your granny in a VTiR 'teg doesn't count :P

Just to add more fuel, on the last OPH cruise last Tuesday, Eric's DC2 vti-r with 1 passenger, easily got a head of a civic vti-r with FULL EXHAUST.

But I think we already know a b18c is quicker than a B16A :)

no my friendz aren't shit drivers.. i race race most of them.. and none of them can take me first and second..

crx sir
integra vtir
civic vti
civic vtir

even the vti can't even catch up.. LOL hahahaah
the rest can

by the way my car is a hatch.. plus integra Ls engine is shit..

raced it b4.. and he lost to me quarter mile 4 car lenght

You don't get it? No-one cares about first and second :P:P:P

It'd be interesting to see how you went up against real VTiR drivers - I have a feeling that they'd take you down in the 1/4 well and truly. FYI, as I said earlier - I can hold with a VTiR myself in the first 2 gears and I have a similar torque curve and output below VTEC... but then they pull away due to superior torque development. The fact that they run primaries and secondary stage engones helps them own a B16A too.

I love reading these bitches. Somehow pete is always involved :P

1st and second is just the start. 3rd is where the real power of the engine is shown. The integra will always win no more to be said.
