The new JDM Civic Type R - FD2

[Evatec]

I have just recently received a complete genuine Honda parts manual for the new Civic Type R recently released in Japan. Received a copy of the Honda advertising brochure as well. I am still looking through the parts manual looking for differences between this new Civic Type R and the previous JDM DC5R. Following are a few things that may be of interest.

As mentioned above, the model is called a FD2 and series 120 ie. FD2-120 according to the parts manual. Surprisingly, the engine code is still K20A with the engine numbers starting at 5800001 ie. K20A-5800001 is the engine number on the first one. The chasis starts at FD2-1200001.

A quick look at the advertising brochure indicates a new intake manifold and valve cover (verified by the parts manual). The block appears the same, but the head has a completely new part number possibly to suit the new intake manifold which seems to bring air in at an angle closer to the verticle (like the NSX according to the brochure) than the JDM DC5R. The cams and valves have exactly the same part numbers as the JDM DC5R, so no differences here.

The crankshaft has exactly the same part number as the JDM DC5R and the AUS DC5R. Likewise for the connecting rods. Piston part numbers are different. The JDM FD2R Civic has a compression ratio of 11.7:1. The JDM DC5R is 11.5:1, while our Australian model is dragging the chain at just 11.0:1. (If you need to put new pistons in your AUS DC5R, get JDM FD2R ones and enjoy the extra torque and power - nb. Advertising plug - I can get JDM R Honda genuine parts from Japan - same applies for Mugen parts and other selected goodies)

The flywheel, clutch and pressure plate in the new JDM FD2R is exactly the same as the JDM DC5R. The AUS DC5R has a slight weight disadvantage, but not that much.

Other exciting things are in the brakes department. The JDM FD2R runs 320mm rotors on the front while the JDM DC5R and the AUS DC5R run 300mm. On the rear,the new JDM FD2R runs 282mm rotors while the other two run 262mm rear units. That would be a nice upgrade for our DC5Rs to run the 20mm larger rotors back and front.

If there are any specific questions on differences between the new JDM FD2R and the DC5R, I'll try to answer them.

hi mate, how much would you esitmate the pistons to cost for 4?

hi mate, how much would you esitmate the pistons to cost for 4?

4 x piston kits (with piston, rings, pin and circlips (11.7:1)) is around $450 plus GST ie. $495 for the set of 4. $20 postage would cover delivery to anywhere in Australia. Just trying to organise a new shipping agent in Japan, so prices in the near future may even be reduced further. Handling charges in Japan, plus air freight to Australia, import duty and GST almost double the listed price in Japan of Honda parts. Hope this helps.

I am very keen to find out if there are any differences in the gearbox department.
In particular ratios and syncro's

[wonton]

do you think the cam that they use on FD2 (just same as JDM dc5r ?) are better than AUDM dc5r?and how much for it

hopefully they fixed the 2nd and 3rd gear crunch with the syncs and dc5 owners can use the fd2 syncs to rectify the problem.

well the jdm dc5r cams is better then audm cams going by the logic that jdm dc5r cams are the same as fd2 then yes the fd2 cams is better then audm dc5r

There have been two revisions to the (3-4) synchro mechanism to handle shifting into 3rd and 4th gears since the original 2001 DC5R was released. The first revised mechanism according to the Honda parts manual came in all DC5Rs from September 2003 until the runout of the model in mid 2004. Basically, if you have a late 2003 or 2004 Integra Type R, you have at least the first revision in your gearbox. The second revision came with the updated JDM DC5R that came out in Japan in Sptember 2004 and I image (haven't checked yet) the 2005 onwards Australian Integra Type S.

The new Japanese Civic Type R (FD2R) has the exact same part number as the second revison mentioned above. Seems like Honda might be happy with the synchro now.

Yes, I did my 3-4 synchro in my 2001 JDM DC5R. Just couldn't shift fast from 2nd to 3rd gear, and then after awhile, couldn't engage 3rd at all. I have pulled the box apart and over the next few weeks, I'll be fitting the latest revision of the synchro mechanisim (already arrived from Japan) to the gearbox. I hope to post a few photos of the damaged synchro (very hard to see the slight wear) and hopefully be able to show the difference between the original synchro mechanism and the latest revision. There may be more here than meets the eye. I measured up the shift fork. The fork appears to have no wear on it at all, but it was outside the serviceable limit as specified by the workshop manual. I have a brand new fork as well and I'll try to get back to this forum with a detailed report on why the original synchro may have failed and what Honda has done about it.

Posted some info about syncros above. Below is a quick view of the ratios in the DC5R and the new Civic FD2R. Hope this helps.

The new Japanese Civic Type R (FD2R) has exactly the same cams as the JDM DC5R. These cams have slightly more duration (keeps the valves open for about 5 degrees longer) than the Australian model DC5R cams. The price for a pair of new ones is about $795 including GST. I have seen second-hand cams on eBay for about half this amount of money, so look around. The advantage of JDM cams is that you don't need to fit better valve springs as one would be advised to do if fitting cams like what Toda (for example) offer.

Evatec,
Can u you advise the part No.'s for the 2nd revision (3-4) synchro mechanism.

Thanks

[tinkerbell]

great thread Evatec

[slipangle]

thanks for the useful info.
