What makes a type r motor?

[losboyfg6]

jus wondering if the 06 si and the type r DC5 motors have compatible parts so the we can convert the K20z3 into a type r motor?

thanx

[sickyute]

the k20z3 is a type R motor...
see the new EDM type R hatch....k20z3 is utilized.

but to answer ur question...the parts from the dc5r can be used.
but there's no point in using them as the k20z3 has dynoed better stock than the z1(which is said to have type r cams).

i'd suggest u use cams for the 2006 tsx....both intake and exhaust...they are the most agressive honda oem cams

what other parts would u be looking for?

[blaznhot_23]

are 06 tsx cams compatible with stock ecu??? wouldn't it throw the idle off a little becuase you have a cam with a different profile than stock...

While I don't know the exact measurements, I can't imagine it'd be a HUGE change over stock so the ECU should cope with it fine. Hondata said it can be used with the stock ECU or the Hondata reflash fine so it should be okay. The question is if the differences are enough to require further tuning to fully utilize the different camshafts, though.

[blaznhot_23]

how much hp can you get from a tsx cam swap??? is it worth all the hassle?

[sickyute]

nobody knows...
everyone just throws out numbers...

it's just a known that u will make power...with proper tuning u'll be able to make even more...

till someone does it the right way and reports back...we'll never know.

actually marvie the type r intake cam has a higher lift in vtec(high cam profile) than the tsx intake cam. the tsx intake cam has a higher lift on the low cam profile tho, so you'll have a little more low-end torque.

the exhaust cam is bigger over all so that's definitely the one to go with.

[blaznhot_23]

how much does a set of tsx cams go for?? what about the reflash if you need it?

so why does the DC5 make 220 hp and the si makes 197?

Higher compression (11.5:1)

higher compression.
different standards for calculating BHP...had we been on last years method of calculation, the Si would be over 200hp.
that amongst other things i'm sure.

yep they changed the rules for advertising HP when the new si came out. SAE wanted the advertised HP to be more accurate. they did this before when automakers would advertise crank HP without any accessories connected.

plus the type r would be tested differently in a different country.

i have no info. on the hytech setup...
sorry can't help u there.
whatever they release will be of high quality though...it will be pricey and will not give u big power per se...but it's an NA setup...u'll pay for what u get.

A. It was 210.
B. After the ratings were changed it was 200 and the si was 197. Pretty close bhp.
C. Still identical whp numbers on dynos.

[fa1]

k20z1 = 210hp / new SAE rating 201hp
k20a1 = 220hp (DC-5R motor)
k20z3 = 197hp / <<SAE rating

[losboyfg6]

did ne one see the car and driver review?

the 05 type s go 0-60 in 6.4 and the si goes 0-60 in 7.3
and the type s getting a 14.9 qt mile

i kno that there are many other comparison test but most of the tests out there prove the the type s is faster.

dont get me wrong, i love the si i just ordered my asm. but u guys are saying there so much alike so then why in all these reviews say the type s faster?

jus let me kno

thanx

Corrected. JDM motors don't have a number after the last letter.

You can't really base the performance of a car off of one test in one magazine. There's a thread in the racing section where a person claims a <14.3 quarter mile in a bone stock Si, and many other magazine tests have seen the Si get to 60 in <7 seconds. Remember, C&D is giving you their best of the very short time they have the car. I've driven both cars and I can't tell you which is faster down a straight line. I can tell you that the Si handles better despite being slightly heavier. In fact my friend has a stock RSXS and I regularly beat him in just about everything driving related in my stock Si.

And adding to that ...

The SI needs to get into 3rd to 60MPH thanks for the High Ratio Differential the Type-S don't need to shift into 3rd.
