increasing throttle response? flywheel or throttle body?

**dsee2** · 24-09-2009 11:56 PM

hi. what's the better option to get better throttle response? i just want more acceleration as it feels too sluggish when flooring it.

1. 3.7kg lightened flywheel (with stock clutch)
2. Bigger throttle body.

Generally, would it be recommended to just get a lightened flywheel and use back the OEM clutch? I'm not sure what clutch i've got as i bought my car from a dealer who cant provide me with any modification details.

Cheers guys.

What intake are you running?
I found that the stock oem air-box was sluggish compared to an aftermarket pod filter. Although despite having felt better throttle response with a pod, I don't believe the power increased whatsoever. It actually probably hindered performance.

Definitely look into getting a cold air intake for starters if you haven't got one, you should get improved throttle response and more of a slightly happy feeling when 'flooring it' so to speak..
I know I definitely haven't looked back since upgrading to a CAI.
This thread is definitely helpful for intake noobies

As for bigger throttle body and flywheel, etc etc. So far, I'll admit that's been well out of my depth and income.

what size are you wheels?
not cheap just to do the flywheel and unless you get itb's or something changing the throttle body won't really do much

get a heavy duty clutch with a lighter flywheel, car will be heaps quicker in the throttle.
What engine btw

does the wheel size really matter? 15".

b16a2. i/h/e done. stock im. what i wanna know is whether it is ok to get a brand new lightened flywheel and use back on my current clutch (I'm not sure what clutch i've got on now as i dont have any history on this). i don't wish to buy a HD clutch to find that i've already got one on!

If the stock clutch doesn't slip with your current power output (and you don't plan to increase that), then you don't need a heavier duty unit. Whether you replace the current clutch (whether with stock or HD) depends on how worn you find it to be when you pull it out. You don't want to be seperating the engine / box again in a few months if you can help it, so I wouldn't reuse the clutch unless it was in pretty good nick, or money was very tight.

For improved throttle response you want a lighter flywheel (mostly noticably in the lowest gears and when 'rev-matching' for downshifts with the box in neutral). Having said that, you need to ask; is your current lack of throttle response (as you are percieving it) actually caused by an overly heavy flywheel, or is there some other issue with the engine?

sorry to hijack.... Currently waiting on installation of lightened flywheel on vtir integra... Is it advised to change the clutch no matter what??? or just wait to see what sort of condition the clutch is in???

It's a matter of preference IMO. I have stock clutch on one of my B18's and a "HD" on the other. The stock clutch doesn't slip under power but doesn't have anywhere near the power transmitting ability (of the"HD") when you're slipping it (off the line for example).

I know what you're saying, and I tend to agree (I personally prefer a clutch with a bit of 'bite', within reason). My point was only that if the standard duty clutch was coping OK then there is no imperative to change it to a heavier duty unit for the sake of it.

This is especially considering that a heavier duty clutch may well be somewhat more expensive, and may also possibly be somewhat less 'user friendly', which may not be to everyone's taste or pleasant in traffic bound city driving (be careful what you wish for sometimes...).
