K20a Aus spec or Jdm H22A type S

[EG5]

well from what i knew off. mate of mine back in indo had a H22a turbo fully built engine for drag on an eg hatch.. hardly touch 10 sec on 1/4 mile due to traction.. always on lows 11..

Which track did he race this h22a turbo eg drag car ? Sentul ?
Havent heard of any 11 sec FWD Hondas from Indo yet.
From what I know Sigma Speed B series powered EG drag car ran some low 12s and thats about it.

what engine is this Toda is talking about

Race engine - Improved production car / drag
TODA 2.4L crate engine (As used in ASM car)
Includes quad throttles / dry sump / exhaust manifold / Tuning data for Motec M800
300hp – guaranteed

the ASM car is a s2000 track car so im guessing it a F20C crate motor.

it was the black eg h22a
i think it was speedZ or something lah .. =X

i'd say go the H22A. will cost less and you have a spare 6g. then you can either turbo it or strengthen the motor with JUN goodies and the upgrade the ecu too.

i personally have seen a few H22As inside old accords and civics. they are a lethal combination. sure the k20a is nice but only if u have the funds for it.

K20A - Good power, good gearing, but costly
B16/18 - Less power, good gearing, cost effective
H22A - Good power, bad gearing, cost effective

The solution? H2B i.e H22A with B16/18 transmission. K-Power and acceleration at a fraction of the cost

ask marc...he's had both type S h22a and a K20 put in his car...

from experience
I’ve had both engines jdm h22 type s and a jdm k20a
I wouldn’t do an aus h22 unless your planning to open it up and build it.

h22 was heavy for my dc2, had to order stiffer rated springs for the front and a few other upgrades mainly to the front of the car to balance the cars characteristics, also its a taller motor so the pan sits quiet low, be cautious about the headers

but if i were you i would stock up on 2 min noodles and get your self a jdm k20

ooh my bad

[hinezz]

i woudnt buy anything else apart from a k-motor, tho its cost alot more, its worth the investment.

Kseries ftw!

What you said got me thinking, so I thought I would play around with the idea on excel.... I wanted to see the data graphically and I found it quite interesting so thought I would share

Using dynos from http://www.importreview.com/dyno.html I tried to find near stock H22a, K20a JDM Type R and B18cR dynos which IMO best reflected the engines claimed flywheel figures.

So assuming ~20% drivetrain loss

=> 220hp TypeR K20a = ~175whp
=> 200hp H22a = ~160whp
=> 190hp B18cR = ~150whp

Note: These are US dynos so readings are high



Nothing surprising here, pretty much what you would expect.

However, whats more interesting is when you graph each of the engine's torque curves factoring in gear ratios....



The 6sp gearbox of the K20a clearly gives it an advantage

And since you mentioned H2B, here is H22a /w ITR gear ratios....



Definitely a big improvement, basically the more area under those curves the better the cars acceleration will be...

Awesome post. Love the comparison.

that H22a only 200hp. JDM type S has 220HP.
