K20a Aus spec or Jdm H22A type S

If the idea is to achieve the best possible 1/4 mile times then you really need to work back from what rpm your peak power is and hence what rpm you want to cross the finish line at. Then what gear you want (ie 4th or 5th) and then look at tyre size. Once you know all of that then you can look at gearbox ratios and final drive ratio.

There's no point going for a combination that lands you halfway through a gear over the line nowhere near peak power. Your just losing time. Its the total combination, not just a bunch of ratios. One combo is not best for all situations.

Yup, absolutely spot on. The best situation is to usually hit your ET right at the end of 4th Gear, so you would want to change your gearing to suit this. Of course, what gearing you go for though all depends on your setup.

This is the main advantage of using a B-Series tranny over an H or K i.e Gearing Options

I do agree, however that doesnt really apply for street applications where the first 3 gears are for accelerating, while 4th and 5th are used for cruising.

[Hyper_Performance]

Thats why a B-Series tranny is also good, as you can have a close ratio 1/2/3/4 for acceleration, and keep the stock 5th for low-rpm driving.

interesting TB + intake manifold design for h22a from Wilson manifold

[hinezz]

fark thats nice man ^^

[fatboyz39]

WOW nice manifold. very interesting design.

[ALLMTR]

If you can source a H2B kit for a reasonable price, you couldnt go past a H22

[HRD2BQT]

d@mn with the TB pointing more of like towards the corner firewall....that'd be a little painful to design intake for that kit ... built in NOS tap/port is a bonus

[myztery]

for the k20a who does it and where plz just what iv been looking for drive in, drive out for 12k

[rayb3na_]

its funny when people bring up the h22a will alter your weight distrubution therefore alter ur handling but have u not noticed u pretty much do that anyway when u strip out the back? it evens affects with a stock motor maybe not as big but its still there.. so stripping out all the interior like fatboyz car would weight at the front really be a problem?

[fatboyz39]

If you have a B series engine equip into EG/DC/EK you can't go wrong with a H2B kit. Even a stock JDM h22a (not type S) with the bolt ons will runs 12's.
