Suntzu's Mod Log

[Suntzu]

in a couple of weeks I´ll have ep3 CTR 1-5th gear and final drive+flywheel. and cause of our crappy stock gearing I am betting that will become my favorite mod

Im pretty interested int his CTR ?? 1-5 gear swap. Ive always said the euro's gearing was , well, wrong..

What is a ep3 CTR, how much and what does it do? And what are you doing to final drive? Very interesting.

[h1coupe]

as you put it, yes the stock euro gearing is horribly wrong
of the 6speed boxes we have the shortest 1st and longest 2-6th gears and also the highest final drive? gearing giving us a maximum calculated speed of 195mph?

the gap between 1st and 2nd is so horrible that it is almost impossible to get reasonable performance out of the car, and that is also one of the reasons that I messed up the 2nd gear syncro?

but anyway the ep3 ctr is the 2001-2005 civic type-R.
so we have

stock vs ctr
1st 3.533 vs 3.266
2nd 1.88 vs 2.13
3rd 1.355 vs 1.517
4th 1.028 vs 1.147
5th 0.825 vs 0.921
6th 0.659 keeping that one for highway cruising.

and final drive
4.389 vs 4.764

after maximum speed will change accordingly.(my rev limit is raised to 7600rpm)
stock vs new gearing
1st 36.42mph vs 36.33mph
2nd 68.45mph vs 55.71mph
3rd 95.04mph vs 78.22mph
4th 125.18mph vs 103.45mph
5th 155.98mph vs 128.83mph
6th 195.27 vs 180.05mph

so you see the gearing will be much tighter.
I can´t wait to check it out

How expensive is it to do this gear swap? I reckon shortening 2nd and keeping 6th the same would be an awesome mod.

BTW heres an updated shot of my front grill.



All my suspension mods are now complete. Whiteline Rear Sway bar, Tein SS, Front tower strut by Cusco and Ingalls camber kit and alignment all done...now bring on the KILLAWATTS!

What was your trap speed at your last 1/4 mile? If you exceed 103mph, you will waste time shifting into 5th without much track left, while the stock car will be able to finish it with 4 gears.

I just got 2runs in befor I busted my 2nd gear syncro and both those runs were bad. launching @2000rpm to avoid wheelhop and better run was 15.022@93.54mph, got 94.xxmph the second run. so I´m not close to exceeding the 4th gear

I just purchased a used ctr gearbox from england and am having the whole internal swapped into my casing, only 6th gear to be replaced.

you can´t shorten only 2nd gear, then you have to change out 1st(they are stuck together on the mainshaft), there is an option to close them better together that is to swap the 1st and 2nd to TSX gearing, TSX has a longer 1st gear making them closer together, and then swapping final drive to 4.764 or 5.062, shortening all gears. I had thought about that, but decided on this.

costs me only the price of the gearbox, it´s beeing fixed under warranty.
cost of the box is something like 1500aud.

Very nice... just get some driving lights in there and you'll be laughing!

[Suntzu]

Yeah ive been tossing that one up but not sure if i need to keep my right fog hole open for some CAI action!

[melloy_honda]

I got my diving lights from US for $70 inc shipping... so its no big deal to remove them later for CAI. Then again there is a tonne of room down there for that.
Where abouts did you get the grill from?

[ig3o]

where can i get these parts for cheap?
-Tein SS Coilovers
-Cusco Front Strut Bar
-Whiteline Rear Sway Bar
