hey guys
would any of you guys know the difference between the type s k20a and the jdm type r k20a? if there is any difference?

any help would be appreciated, thanks!

 

k20a R has 20 more hp i believe

 

Type S

6 SPD
201hp @ 7800 rpm
140ft/lb @ 7000 rpm
11.0:1
8100 Redline

Ratios:
1st 3.267
2nd 2.130
3rd 1.517
4th 1.147
5th 0.921
6th 0.738
Reverse 3.583
Final 4.765


K20 R

6 SPD LSD Hydraulic
11.5
220hp @ 8000
158lbft @ 7000
8400 Redline

Ratios:
1st 3.27
2nd 2.13
3rd 1.57
4th 1.21
5th 0.97
6th 0.78
Final Drive 4.76

Not too keen on the K20's, but Im pretty sure there along the same lines as the difference between R and GSR motors.

I.E Pistons, cams, head flow, improved flow on header/exhaust system, etc.

Not sure why the question is asked, but if your thinking of a swap, go with the R motor.

 

isnt that the specs for the k20z[something]

the k20a2 [ 02-04 type-s motors ] didnt have the 4.7 final drive

 

yeah i think thats the new 05-05 rsx-s specs, k20z3 or z1 or something i forget

 

typeS - K20A2
typeR - K20A

05+ type-S = k20z1

Supposedly, the current -S has the same cams as the Type-R motor.

Things helping boost the ITR K20A are the higher compression and 4-2-1 header. I'd expect the ECU to be tuned a little more aggressively, too.

 

i believe the current S motors' cams are different p/n's from the R, but virtually identical otherwise.

my thoughts on hte swap, go with the k20a for hte "jdm poitns" whatever the expletive thats worth

for the saving in money, i think a k20a2 with type r tranny or even fd is a better idea

 

k20a2 is better for boost
k20a if you plan to stay all motor

a boosted 11.0:1 CR motor?are you crazy?

 

a better choice than the lower compress. k20a3 because of hte stronger internals. best k series to boost is the a2

the guy filming in the second link sucks at filming, he can't hold still at all and doesnt know how to properly use the zoom. other than that, it looked like a close race in the second. in the first one, that hatch just whipps that porsche

The A3 internals are NOT stronger than the A2.

The Z1 cams are PRC cams, which means they are TypeR.

The K20A makes its extra 10 hp over the Z1 from a larger intake manifold, .5 higher compression, different exhaust manifold, freer flowing axle back exhaust, and a tune that is for 95 octane fuel with 300 more rpm redline.

 

i think the period after compress threw you off.

a better choice than the lower compression k20a3 because of the stronger internals, the best k series to boost is the a2.
