the K20 is an awsome motor from stock, but limitations for the various countries it goes to (polution,noise etc) prohibits honda from certain boltons that will further the motors power capabilities, thus what are your thoughts on complamentative parts (boltons) to make an Unopened k20 perform at its peak
many users are quite weary when it comes to "head work" etc and some just prefer an OEM motor
So what "IS" the best setup for an unopened K20?
DYNO figures to back up claims
as everyone else would say, intake, headers, cat back exhaust, aftermarket computer,and bits and pieces here and there.
if all work has been carried out right in the first place and your engine is well maintain. the motor will be in good knick, to get the power down to the ground with some clutch and flywheel work also with the right suspension and right select of tires you will have and awesome K.
best off the shelf boltons for your money IMO are as follows:
Injen Intake
Toda headers
Custom 3" catback/3 inch highflow metal cat
here is my dyno sheet before my head work, just with the above mods and kpro:

RBC manifold will do wonders for a K20 engine
nice figures 2002teggy, and i know what ur getting at JDM.power but i want to know the best of the best setups eg QTB's which headers 4-1,4-2-1 etc kpro or other ecu
off tap mods :)

easy power with intake, SSR/DTR header, 3in exhaust and a good kpro tuner
^^is that a JDM K20A?
qtb dyno sheet neone?
good figures ctercii, who was the tune done by?
yes it's a jap motor, it's tuned by Dave from Insight Motorsport.
yeah top of the lines Brands, you pay for quality you end up with awesome results, TODA.au are one of the best if your looking for good power and qtb's setup. cant never go wrong with toda parts.Quote:

no everything else is standard...Rcrew 3in exhaust, AEM intake and SSR header....
oh ok, very nice...jdm k20 ftw
difference between jdm and audm k20's? tuning or more
Jap Spec has : 8400 red line (8900 cut out), 162kW/200Nm (147/192 AUDM), VTC works on both the intake and exhaust cycle (AUDM just intake), variable pressure exhaust sytemQuote:

really, vtc only works on the intake, what a jip, how do i fix this?
You can't on a Honda. Until they release a new engine with it.Quote:

I thought the k20z1 out of the type S has VTC working on both intake & exhaust
i thought it was only the k24 that had vtc only on the intake.....what a pain, should have built an eg instead, who wants to buy my EP3?Quote:

Two versions of Honda's i-VTEC system can be found on K series engines; variable timing control (VTC) can be found on the intake cam of both versions. The VTEC system on engines like the K20A3 only operate on the intake cam; at low RPM only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the combustion chamber for improved fuel atomization. At high RPM, both intake valves open fully to improve engine breathing. In engines such as the K20A2 found in the Acura RSX Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles
what for, i now think its a piece of SH!t, might as well have the d16 single cam vtecQuote:

Nah bro relax, Ep3's are cool, my friends dad used to own one and he was a females magazine editor!Quote:

so VTC is only a fuel saving thing, and vtec is still both cams using the 3rd lobe when vtec kicks in??Quote:

VTC on intake cam for fuel saving and midrange torque, and you still have 3-lobe VTEC on both intake and exhaust cams for some high RPM screaming goodness. :thumbsup:Quote:

is the rbc manifold similar/same to the manifold on the jdm k20? PRC i believe?Quote:

ahh kQuote:

isnt the RBB used on the FN2R? 100% sure that the FN2R does not use the RBC...Quote:

yeh, as stated i said FN2R not FD2R (although i think the FN2 and FD2 use the same RBB manifold)
No, RBB is used on the Accord Euro. FN2R uses RSP. You can tell from a photo of the engine.Quote:

RSP is like the aussie civic R ones?
Maybe they couldn't make up their minds. lolQuote:

Not to sure, gonna have to ask some1 that got a lil more experiance than me.Quote:

also with the headers being on the firewall side, does that free up alot of the restricton as apposed to a normally mounted motor?
We ran ITB on a stock internal jdm k20a before without aftermarket cams.Quote:

how did it go yonas? what QTB's, and who tuned it ?
TWM brandQuote:

got the dyno sheet laying around :pQuote:

do you recomend it or same as a good intake manifold?
