ITB's on k20a3

[3Peat]

Hey guys, I just bought an ep3 yesterday. Sold my boosted ek, and wanted to start over again...
I'm thinking of getting itb's. Would i need a re-tune cuz of increased air flow or what? I've never went with them before, so i just wanted to know what goes on with them, what can i expect to gain, and if i'd need a re-tune.
Thanks in advance.

This is what twm or clockwise motion told me, don't waste your money on the a3. But if you did want to go with itbs; for me my setup would consist of the kinsler itbs (which might not fit(not enough space)) and a set of IPS cams. Don't waste your money on twm, they don't produce good power compare to kinsler, but if you do get the decent deal on k20a.org for about $1000, go for it, but not on the a3.

Put a K20A2 swap in first.

[3Peat]

yeah, i really wanted to swap, but i'm low on funds..

[VIZHUNZ02SI]

swap first a3 is useless unless you're an eco driver

[sLiCk]

you are low on funds but you can afford to get itb's?

[lbk02si]

You're gonna be even lower on funds if you try and make any serious power with that a3.

yeh, i talked to my buddy and he told me the same thing. I'm gonna swap an a2 head..

Fixed :mbiggrin:

Just a very short piece of advice, the costs and time involved in a head swap are about the same as a complete A2 swap.

Hell a brand new in the box K20Z3 short block is only 1700$ from Honda! Dont waste money on trying to get whp out of the A3 shortblock without boost. The gains of ITB's over a RBC on a A2 are not all that great and only when large stage2 cams or better are run and anything but WOT with ITB's are a great compromise in drivability. ITB's and a DD do not mix very well.

so you're saying i prob shouldn't get itb's if this is my dd? better choice with a RBC?

[3Peat]

Fixed :mbiggrin:

haha nice.

[heyvortek]

everyone is saying dont do anything to the a3 unless its a turbo. best choice is to swap with something such as a k24a1 if your low on funds.

That is not really what I posted, I stated that was on a A2. On the A3 BOTH are a serious downgrade for a DD and the ITB's are surely the low man on reliability and drivability. Sure they make more top end whp #'s, but seriously underperform at anything below that point.

Making NA horsepower is by far the most costly route to go, each step costs big $ for ever decreasing WHP gains the higher you go, and your core shortblock must be up to the task or you are simply wasting money.

doesn't the k24a1 have the same amount of hp that the a3 does?

[ep3jd]

doesn't the k24a1 have the same amount of hp that the a3 does?

Yeah, with more torque. But an a2 head swap on that makes good power with the right tune

thats what i figured.

Btw, itb's are a bitch to tune for a dd. Conditions change every day, and unless you're a tuner, you'll have to retune it every day.

oh okay.. thanks man

[j0000stin]

yes but also has more tq and has thicker rods. not those POS toothpick rods the a3 has.

hell ive seen someone make 400whp on a boosted k24a4 and that was with stock internals.
