Hi,

For a 1999 Integra GSR, which parts will give the most performance? Perferably the number of HP out of each part.

Stock HP of a GSR: 170hp (crank) - 20% (34) = 136hp to the wheels.

Parts:

CAI:
Headers (DC):
Lightened Flywheel (8lbs):
Lightened pulleys:
Lightened cams (AEM):
Skunk2 Intake manifold:
Exhaust system (Greddy):

And anything I may be missing and is a bolt on.

Thanks everyone.

 

gt**r turbo, does that count?
lol

 

Heh, I guess a Turbo IS a bolt on. I'm talking about things that don't cost more than say...$600.

Thanks

 

Firstly, a couple things. 20% powertrain loss is pretty steep on a FWD manual tranny. It's closer to 15% and most stock GSRs make around 145whp stock. There's only one header.

CAI might get you a couple, exhaust will get you some, IM will do the same, DC makes shitty headers with exception to their JDM design, which will net you better gains. You might consider a testpipe or slightly larger cat. And as far as I know, AEM doesn't make cams unless you meant to say cam gears, which combined with pulleys, still won't gain much on a basically stock motor. A flywheel won't do much for you either.

My suggestion, forget about the flywheel, pulleys, and cam gears for now, and just stick to the bread and butter bolt ons that you have started to mention. Judging by the errors in your post, I think it's safe to assume you lack the overall requirements to be serious about making a lot of power.

Search and do your homework.

 

So 145whp is more like it.

CAI
Exhaust
IM
Headers
Larger CAT

So when would a flywheel, pulleys, and cam gears be of any use for noticeable gains?
Yes, I am a n00b (hence the Trial user title). I will be getting this car sometime soon.

Thanks

 

You have to build a system, a component alone wont get you gains. Like to see a gain out of an exhaust, you have to pair a header, highflow cat or test pipe, piping, muffler, it all has to be sized correctly and planned. Same goes with the intake side of things, you have to think about intake piping size and length, then the TB, then the IM, then the cams, then the valves. It's all one big chain of things that need to all be done to work correctly together. Tune to see gains.

Just lego-building will not get you anywhere, you could be spending 2,000 dollars on boltons and not see any more of a gain than 10hp. Or you could plan out a system and spend that 2,000 dollars on parts that work together and see gains more like 35hp.

Don't get too wrapped up on boltons, you aren't going to see any lightning speeds with just boltons, it's expensive to build these motors to be fast. Boltons aren't going to get you very far.

 

sorry bud, you're not going to get 35whp gain from bolt-ons. GSR's in race trim don't make 35 extra whp.
