'07 Civic Type R USDM

[Ainokea_Si]

Can this be done? I was reading online and it said that the type r motor has a 11:5:1 comp ratio and I know that si motor runs 11:1. I was wondering if the ratio that I was even reading about was the British motor and not the jdm one. I also read that the throttle body and intake manifold has increased size and has been polished.
I was interested in the feedback from you guys because i was wondering on making one. i know that the pistons and rings, retainers and all the internals make the comp higher but has anyone seen a Si with jdm type r cams?
what can we do to make one besides spending as much money with rebuilding the block which at this point would be better if I just imported the motor from japan.

alot of the parts off of the type r would probably be a drop in w/o any major issues but the key issue in utilizing the higher compression pistons or larger throttle body,etc (from the type r) lies with no tuning unit to tune the car for the changes these parts will create (more air flow, compression,etc). therefore, who knows what you'll gain if any at all if these parts were installed (the stock si ecm might compensate to an extent but we all dont know how well far it can go). granted, it would be very interesting to experiment to see how the si's ecm reacts to these typ r mods.

On September 13th Honda is going to release another version of the Civic dubbed the Honda Civic Type RR, in Japan. Japan already has a more powerful version of the Civic that we don't get here in the US, the Civic Type-R. The Type-R is already more powerful than our Si model with 225HP and 158 lb-ft of torque. The new Type RR version will come with even more power at 240HP and 160 lb-ft of torque. The estimated 0-60 mph time for the more powerful version is 5.8 sec.

The RR version of the Civic is 22lbs lighter and gets a dual exhaust system. The car also has a modified suspension and braking system thanks to Mugen.

So what is the catch? Well the car lists for $40,000! Honda has stated that the Civic Si Mugen that we are getting this fall will start just shy of $30,000. Well $40,000 probably would be too much for a Civic, even if it has 43 more horsepower than the regular Si version. That probably explains why Honda is only going to make 300 of these cars and in only one color, red.

i wonder how much the oem jdm typ r mods are for the civic? is it worth it? the rr is alot more powerful too

[o-hatch]

Anything off a Type R comes at an Hefty price.

[Ainokea_Si]

^agree
the mugen is about 8 to 10 thousand more and the rr is about 40000 retail. the type r hatch has same output number but the jdm type r has more for around the mugen price so it cant be that much more. the mugen imo is just a pretty si. body, suspen, access, rims, no performance mods

the jdm civic type r has a higher compression ratio and improved breathing efficiency help the naturally-aspirated K20A 2.0-liter i-VTEC engine output a maximum of 225 bhp at 8,000 rpm and a maximum torque of 159 lb-ft at 6,100 rpm to the si Power bhp 197 at 7800 and torque lb-ft at RPM 139 at 6200 rpm

you can upgrade your cams ( to either 06 tsx or some aftermarket stage 1's) w/ the basic bolt ons (intake, race header, exh., etc) and be right around 240hp ( X showed it with his setup (tsx cams) 232 dynapac~240 base hp and my setup: skunk2 stage 1 w/ basic bolt ons made 218 dynojet horsepower~240ish. i also agree that anything type r will be costly.

like two or three years ago i was reading some import magazine and the front cover story was bringing the type r over here, is there any rumors goin on about this that anyone knows about???

[Ainokea_Si]

your h/i/e bolt on and cams made 218? that sounds nice but torque wins races and horsepower is for sale. did you have the reflash too?
this sounds like under $2000 for the same output of the type r. but what is was your torque rating? that is what throws you back in your seat

i think that was a confusion because they brought a type r to europe but in a hatch. the articles i have read talk about a civic r and the civic rr but those both cost more than the usdm mugen

[hawjdude]

im on stock ecm right now. my peak torque is 154. if globs of torque and winning races is your game, frankly, you're not gonna get much from the k20z3. its not the best in racing and torque production is limited as it is. if you wanna be put in your seat like how you say, i'd recommend turbo,SC, or nitrous (even that in itself doesn't produce that much torque). otherwise, ur gonna have to change cars to a RWD V8 or something of that sort.

that's and oxymoron, USDM type r (:

no i have 6,000 for the front clip and rear clip and want the motor and not be a wanna be.... lol j/k

i have seen some si that throw you back, i read in a thread that forced induction reduces the life of the car. i want type r power n/a. this is always nice because of the sleeper effect

do you not agree? 225 n/a not possible?

[rp215]

I imagine a motor swap with an ecu swap could be done.

Except the Type R is so much more than 20hp. Different bushings, reinforced frame up front, removed sound deadening, Brembo brakes, different suspension, sway bar thickness, different underbody structure to optimize airflow and reduce weight, etc etc.

My point is your car won't become a CTR with some swaps here and there. Your car isn't a CTR, and it'd cost a boatload of cash to get it to a CTR-level.

i'm suspecting the chassis to be very different perhaps? since we have different codes right? FA5 -> FD2. The RSX type-s had the same code right? Dc5 from USDM to JDM version right? What's so different about the chassis on the FA5 vs the FD2? (jjust curious)

It all starts with a Base (Dx,Lx) model, then upgrade from there.

225 whp is definitely a good goal for NA. if you gots the money, might as well switch the maf out for the map (rsx) and do cable throttle (rsx) and then kpro. i say this b/c i dont know how long it will take hondata to release a tuneable unit for the si. w/ the rsx setup in place, you'll be able to do 250 NA power easily. my opinion on torquey and being placed in your seat might be diff. from yours. i've only experienced this in AWD and RWD cars (supras, american muscle, evos, etc). i've had a 300whp gsr civic and it picked up fast good but it lacked that torquiness that imo keeps you pinned in your seat.

have you done this before?

[hawjdude]

i haven't done this. it would take quite a bit of money and time. but, if done so, you can tune your car for any kind of modifications you implement to your car.
