Guest nixon Posted May 13, 2002 Report Share Posted May 13, 2002 this was about what swap i should do for crx. Now its over who knows more about the engines. lol will the arguing stop? Quote Link to comment Share on other sites More sharing options...
04r1 Posted May 13, 2002 Report Share Posted May 13, 2002 I would just like to say Rob you are correct about the VTEC KILLER CAMS. They are called exactly that and are made by Toda Racing, a highly honorable player in the import racing world.

rl Posted May 13, 2002 Report Share Posted May 13, 2002 lol, yes! back to the original subject...did you decide on doing the zc+turbo swap yet? Quote Link to comment Share on other sites More sharing options...
04r1 Posted May 13, 2002 Report Share Posted May 13, 2002 Oh and one more thing, check out this link http://www.todaracing.com/B162.html . Notice the picture of the civic hatch turbo at the top of the page. It is on the page with the VTEC KILLER CAMS on it. I wonder why he changed out his stock VTEC cams?

Crane Cams also makes something similar (although I think the actual technique of doing so may be different, same effect). Quote Link to comment Share on other sites More sharing options...

I didn't realize you were talking about turboing a B16A. If you do just a B16A swap CORRECTLY there is no tuning needed. If you turbo a B16A properly, there is not much tuning needed, but extra tuning never hurts and would definitely help in most cases. The blue box Greddy gives you in the 92-95 kit doesn't allow for any adjustment, so I don't know what tuning you are going to do with it. Also, it does not retard the timing. You have to do that yourself by mechanically retarding the distributor. The blue box stops the MAP sensor from seeing boost, and therefore prevents the CEL from coming on. It also acts as a boost dependent fuel regulator to richen the air/fuel mixture under boost. Quote Link to comment Share on other sites More sharing options...

I have presented extremely thourough answers here, now it's your turn </font>I was just fucking trying to lighten up the conversation between you and Rob. I do not own a VTEC motor and do not care to so I do not read up much on VTEC motors. I know the whole idea behind VTEC and how if tuned right, it can make more power than a non vtec turbo or non turbo motor but if we get back to the whole point of this post, it is about hp for dollar. I can take my non vtec motor and get headwork done to it to flow way better than a VTEC head. The cost is still less than if I would have bought a VTEC motor. I am not doubting your knowledge on cars or motors at all. It can just get very expensive and this guy from what I understand does not want to spend a ton of money off the bat. Anyway, this whole post is getting old so Im done. Quote Link to comment Share on other sites More sharing options...
slow4now Posted May 13, 2002 Report Share Posted May 13, 2002 Yes, I am done with this as well.It is obvious that my words are falling on deaf ears for whatever reason. My intention was never to ruffle feathers or try to pump myself up, I just wanted the original poster to have as much correct information as possible. I have seen tons of misinformation on numerous boards and it gets old quick. I have been wrong many times myself, and even though I absolutely hate getting proved wrong, it is part of the learning experience. Heck, just a month ago I had a misconception about something engine/turbo related and FINALLY had a conversation with a friend that lit the lightbulb in my head, telling me what I had previously thought was wrong. It wasn't anything he said specifically, he just kept asking me why why why and finally I told him something that was wrong, and he told me why so. Anyhow, good luck everyone with your cars and endeavors. I'm sure we will meet sometime and hopefully will have civil less-cerebral conversations. If anyone has any questions feel free to PM me and I will answer them the best I can, or will point you in the right direction. Later!

Guest nixon Posted May 13, 2002 Report Share Posted May 13, 2002 what will i be left with power wise once ive done the zc swap with turbo? Quote Link to comment Share on other sites More sharing options...
slow4now Posted May 13, 2002 Report Share Posted May 13, 2002 I would guess about 130-140 wheel horese power, but trbocrx would know better than I. Quote Link to comment Share on other sites More sharing options...

I would wager to say he is pretty close to the 200fwhp mark now with a hair more boost and his fuel problem figured out. thats a dead stock motor with a turbo (pulleys and exhaust of course) [ 13 May 2002, 10:50 PM: Message edited by: rl ] Quote Link to comment Share on other sites More sharing options...
04r1 Posted May 13, 2002 Report Share Posted May 13, 2002 I dynoed at 186.4 fwhp and 173.1 fwtrq on around 7 pounds of boost and no fuel. According to the wide band O2, I was running a 15.5 air fuel ratio which is dangerously lean. I was able to turn fuel up a little but not much. I have since then added a s-afc to get more fuel to my motor and am awaiting the next dyno day from Brian. I am also running 11 pounds of boost on it now too since I now have fuel. This current setup should put me around 210 at the wheels. Keep in mind this is on stock honda internals. Quote Link to comment Share on other sites More sharing options...
04r1 Posted May 13, 2002 Report Share Posted May 13, 2002 Just to give you something to compare that too, I have a dyno graph in front of me of a B16 Hatch with intake, exhaust, header,no cat and it only put down 151 hp and 107 torque. Keep in mind I have way less money in my engine too than the B16 setup. Just something to ponder. Quote Link to comment Share on other sites More sharing options...

(maybe not ) Yes this can be done since the majority of the valve overlap is in "vtec range", but then remember you are essentially using only the smaller lobes on the cam, in a sense wasting the larger profiled lobes. The best solution in my opinion is a combonation of the v-afc and cam gears. Quote Link to comment Share on other sites More sharing options...

integranator Posted May 15, 2002 Report Share Posted May 15, 2002 If You're really really thinking the money situation, and not going to run super high amounts of boost. My friend w/ a civic ex AUTOMATIC (vtec sohc) has the greddy kit on it, and was running EXTREMELY lean, we're talking off the charts lean! like 18: .7 and still put down 150+ torque on an automatic mind you at 7pounds-ish. With enough fuel, he could be right up with trborex's numbers. We couldn't dyno the hp, becuase he woulda blown his motor on the high end. This motor only costs around 6 hundred dollars too!! So, thats another thing you could do, its all about preference. Quote Link to comment Share on other sites More sharing options...
controler Posted May 15, 2002 Report Share Posted May 15, 2002 If your talking Horsepower per dollar, (turborex) have you thought about a B20 + turbo? I know the motors can be had for at or around $1,000, and they have LOADS of torque. Much more than any other b-series motor. Or even B20 with a vtec head. I've seen them dyno 200+hp (fully build though) but I bet you could get away with stock pistons, even stock type r pistons, for under $3,000, and still dyno at 190+hp.
