Hey guy, my car is slow even with Apexi Header, AEM CAI, Tanabe Catback. Can anyone tell me why? Do I have to do anything else? is that because of the OBD2 computer? Do I gain more horsepower by switching to OBD1 computer? Or they both the same?
Thanks~

 

Well, it's not as cut and dry as just being slow, and what you need to do to get fast. It's like climbing a hill, and, at least according to you, you're sitting at the bottom of the hill. And, the question you just asked, is how to get to the top if there is no sidewalk. The answer in a round about sorta way, is any way you want.

As far as making your car fast, Intake, headers, and exhaust by themselves really don't give you much in the way of horsepower, and just to switch to OBD1 really won't give you anything other than tunability. If you want to get "fast", plan on spending thousands of dollars. If you want to go as fast as some of the guys that have put turbos on their cars, or cars that are fast factory like a Vette for example, plan to spend at least 5-7K and more if you plan to keep it all motor.....

What do you really want out of your car, and how much are you willing to spend?

I really don't want any thig like supercharger or turbo! I need NA work, like port polish, ....
Do you know what should I do to make my car more powerful, If I willing spend $5000 - $8000 in the motor.

 

oooh, project.....yeah, for that kinda didge, you should have no problems making your car plenty fast. I'd bump your compression up somewhere in like the 12:1 range, using a set of say JE pistons, or something along those lines, a set of crower rods (anything but eagle), some Toda Spec-c or Skunk2 stage 3 cams, and mod your stock manifold to use a 70mm taper bore throttle body, a nice header, test pipe, and exhaust, adn you should be golden. Keep in mind, I only mentioned the main components, you're gonna need a lot of little peripherals such as springs, retainers, injectors, fuel pump, ECU/Hondata/other stand alone, etc. But it's a good start. You may also want to very seriously consider sleeving it to a 2 liter. I'm doing a build up right now with a set of Darton sleeves, that I'm hoping should turn out very nicely.

Any way, good luck with it......

hey Aj, what do you think of changing the block to handle way more horsepower then the stock block can handle. here's a guess, but i think if your serious about performance you have to start from the ground up. would you then consider buying a for instance a Dart block to handle horsepower to and exceeding 500 HP? obviously forced induction is in the mix so what do you think? :twisted:

Well, I'm planning on using a set or darton sleeves on a brand new ITR block, in my case becuase I put a hole in my old one, I was forced to buy a new one. Any way, the Dart block is a good foundation, but realistically, isn't at all necesary, even with a crazy turbo setup, for a fraction of the cost, you can have like AEBS or Golden Eagle sleeve your block to anywhere from 83-87mm which at the high side of 2.1 liters is pretty damn big. The Dart block is over 2G's and that's not inlcuding anything other that the actuall block it self, and I mean nothing. You'l spend at the very least another thousand bucks on crank, pumps, bearings, and other stuff just to get it even close to being usable. In any case, if you're asking my opinion, the dart block is a nice piece, but much like a Mugen valve cover, it really doesn't do a lot for how much it costs.

Thanks bro!
