Lojik Posted June 4, 2002 Report Share Posted June 4, 2002 I have a b16a2 vtec in my civic. I am trying to find some ways to add more power. It has a few mods (air intake, headers, ignition, fuel rails, pump, regulator. . .) I was told it is pretty tricky and not worth the money to turbo a vtec engine. let me know what you guys think. thanks. Quote Link to comment Share on other sites More sharing options...
Mr. Jones Posted June 4, 2002 Report Share Posted June 4, 2002 As far as I know most people eliminate VTEC when going turbo on the honda engines as the massive overlap allows boost to fly right by. smile.gif Think they are "vtec eliminators" or something Lata Quote Link to comment Share on other sites More sharing options...
Guest Iria Posted June 4, 2002 Report Share Posted June 4, 2002 Greddy makes bolt on turbo kits for b16s so it's not impossible. I think it just takes more careful and precise tuning. Or I guess you could always somehow just disengage the VTEC. Quote Link to comment Share on other sites More sharing options...
Lojik Posted June 4, 2002 Author Report Share Posted June 4, 2002 Hmm. . .sounds like a summer project. Any other ideas on gaining power from a 4-banger? Quote Link to comment Share on other sites More sharing options...
slow4now Posted June 4, 2002 Report Share Posted June 4, 2002 The only downside to having a turbo on a Vtec motor is tuning the point in the powerband where the Vtec crossover occurs, many times there is a dead spot before the high lift cam profile. Oh, another bad thing is traction, as you wont have much! [ 04 June 2002, 10:16 PM: Message edited by: slow4now ] Quote Link to comment Share on other sites More sharing options...
integranator Posted June 4, 2002 Report Share Posted June 4, 2002 well, the reason that people might say that your motor is hard to turbo is because your compression ratio is high for a turbo. Correct me if i'm wrong, isn't it somewhere around 10.6:1 ? Turboing a b16a would make it very fast, because it has one of the most free-flowing heads honda makes. So, all in all there's not a problem w/ turboing that motor, just don't try to run alot of boost Quote Link to comment Share on other sites More sharing options...
Guest nixon Posted June 4, 2002 Report Share Posted June 4, 2002 i thought best thing for b-series engines was a supercharger not a turbo. Quote Link to comment Share on other sites More sharing options...
ovrwght Posted June 4, 2002 Report Share Posted June 4, 2002 i know a guy with a 98 civic with a greddy turbo, fmic, and a profec-b, along with an upgraded fuel system and it puts down 220 at the wheels, its a D16 SOHC btw. Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted June 5, 2002 Report Share Posted June 5, 2002 Originally posted by nixon: i thought best thing for b-series engines was a supercharger not a turbo.i live by the best thing for any car is a turbo. although it may be easier to super them. Just do a non-vtec head swap or get vtec killer cams, either will not be cheap, but the cams will be easy(er). I'm not vtec expert though, I'm sure there is a way to do a vtec and a turbo safely, efficiently and do it streetable , go do some research. You absoutley will have massive traction problems, esp. on stock suspension and tires. Quote Link to comment Share on other sites More sharing options...
Guest badmuthrfkr Posted June 5, 2002 Report Share Posted June 5, 2002 99% of the people around here don't know how to build or tune a Honda for shit. There are people with experience such as Brian R. But most shops are clueless(around here). Quote Link to comment Share on other sites More sharing options...
Scotty2Hotty Posted June 5, 2002 Report Share Posted June 5, 2002 Always heard from everyone on honda society roll with the NON-VTEC platform if wanting to run a turbo, depending on boost kick down compression, forged pistons, boost controller yada yada. But on the non-VTEC it's true the higher band cam doesn't have the switch over point where it goes into the high RPM's. But you still can turbo a VTEC motor. I say roll with a kit not a custom fabbed turbo. Kits are a lot easier, so roll with the greddy like IRIA said or I'm thinkin of a place in florida that sells all out kits too and they said some stage kit their civic went 12's. something to look into.

04r1 Posted June 5, 2002 Report Share Posted June 5, 2002 I think if it is tuned right,(Your best bet is to read up on it and try shit yourself, dont trust a shop) you could have a fast VTEC turbo Honda. My friend just put a Drag Gen 3 kit on his 98 Integra GSR and that thing pulls like hell. He could have killed my Turbo setup but there is also alot more money involved. Just take your time and tune it right on low boost before you go trying to turn it up too high. Quote Link to comment Share on other sites More sharing options...
Guest badmuthrfkr Posted June 5, 2002 Report Share Posted June 5, 2002 There is a guy I know, Brian, not sure if he still works at Immke, but he had a red EK h/b with a B18 and a turbo. Put down 386fwhp. I forget the specifics on his car though. But it was plain jane sleeper from hell. Quote Link to comment Share on other sites More sharing options...
04r1 Posted June 5, 2002 Report Share Posted June 5, 2002 I think I know of the car you are talking about. I havent seen it since last year though. Is it red with no bodykit or anything on the outside. Just a huge ass Dunk exhaust that you could stick a football in. I remember this car from a show last year over by easton and he pulled out a dyno sheet that had some kind of a 3XX fwhp figure on it. Damn nice sleeper.

Guest nixon Posted June 5, 2002 Report Share Posted June 5, 2002 trborex would a integra 98 gsr be the same in performance wise as a 95 one? just 95 front body trim is a little different i think. Quote Link to comment Share on other sites More sharing options...

That car was CRAZY fast. Little red hatch with black steel wheels......I was sad to see it go. Quote Link to comment Share on other sites More sharing options...
Guest extheflow Posted June 5, 2002 Report Share Posted June 5, 2002 you could always find someone with an LS integra(aj) and trade heads...you might even be able to trade up enough to get yourself some lower compression pistons. then slap your turbo kit on that. problem solved Quote Link to comment Share on other sites More sharing options...

What do you think the pro-import racers (especially in Japan) have been running, while they are telling you they run 8.5:1 ? Quote Link to comment Share on other sites More sharing options...
