Vehicle/Tune - Prelude

Installed new MFactory FD gears, LSD and more

프렐루드 종감속 순정 비가 4.266엔데 4.64로 바꾸면 각단의 기어비가 짧아져서 최고속은 줄어들겠지만
일정 속도 까지 차가 빨리 도달하게 됩니다. 물론 좀더 쉬프팅하는 텀도 짧아진다.^^
해서 국내에도 여러 사람들이 종감속 기어비를 많이 바꾸어 만족할만한 성능으로 끌어올리곤 한다.
하지만 최고속에서 20`30키로정도 줄어들것이며, 고유가시대의 연비도 조금은 나빠진다.
트랙이나 와인딩을 즐기는 오너라면 확실한 효과를 볼듯 하다.

MF팩토리의 프랠용 종감속 키트는 50만원정도의 가격이며 배송10만원 그리고 인스톨비용까지 합치면
70~80만원정도 예상이 된다. 한때 할까말까 고민도 했지만..
트랙주행을 딱 한번 해본 나로써는 일상주행에 더 촛점을 두게되어 포기했었다..ㅋ
하지만 또 언제 마음이 바뀔지는..ㅡㅡ;

아래 또 언급하고 있는 경량 플라이휠...이것도 구동축을 가볍게 해주어 좀더 엔진의 반응이 빠르게 하기위한
튜닝인데..역시 서킷이나 와인딩에서 유리하겠고 고속이나 탄성 주행을 할때는 오히려 무게가 가벼워
그만큼 탄력을 받아 계속 도는것 보다 일찍 관성을 잃어버려 다시금 가속을 해주어야하는 단점이 있다고 한다.^^
하지만 그차이가 미미하기에 경량 플라이휠 정도는 일상주행에서도 해봐도 될듯 하다.

사실 엔진스왑전 경량플라이 휠을 장착했었는데 스타트와 저속주행때 차가 경쾌해 지긴 한다.
몇일 지나니 그 감각이 일상화 되어 별 감흥이 없었지만..^^;

I have had my car apart for the last few months working on several projects getting ready for the up coming race year. I got everything back together and took a test drive. I figured now would be a good time to post some pics and general 1st impressions of the parts. I will do a follow up after several days on a race track to keep everyone updated on how well they all hold up. What I installed over the winter:

Exedy S/P ORG clutch (30% more clamping force)
Sold Here

Kaiten light weight flywheel (chromoly steel 8.8LBS)
Sold Here

Quaife Differential (LSD)
Sold Here

MFactory FD 4.64 Final Ratio gears
Sold Here

New OEM differential bearings, transmission oil seals, thrust shims from

Everything looked like it was made with top notch quality, especially the Quaife Differential and the Infinitued FD gears. Very solid construction on those 2 parts!

1st thing I did was follow the factory service manual steps for removing the transmission:

Transmission out, you can see the OEM flywheel. It was time of a new one, I had heat spots and little stress cracks all over it.

Transmission on floor.

While the tansmission was out I put the new flywheel and clutch on. (the bolts that hold the flywheel on, are really on there! I had to use a real long pipe over the braker bar). Below is a picture of the new clutch and flywheel installed.

Next I cracked open the transmission. There was a thin layer of black grimy oil on everything so everything got a cleaning with WD-40 before it went back together. Other than that the OEM parts looked good.

I then removed the OEM differential and counter shaft, pictured below.

Using a big ass bench vice and blocks of wood I removed the final drive gear from the OEM differential. I needed the bolts to install the new FD gear on the new LSD. I also used a gear puller to remove the gears, syncros, bearings, ect.. from the OEM counter shaft. They needed to be installed on the new infinitude counter shaft.

The gears slid right onto the new Infinitude counter shaft, with perfect fitment. Below is a picture of them on the new shaft. I also checked all tolerances of the OEM gears and bearings and everything was well within tolerance. Got to love how well the OEM Honda parts hold up even when you beat the hell out of them on the track over and over and over.

Everything cleaned and re-installed into the housing. New FD gears, New Diff, New Diff bearings, New thrust shims, and New oil seals.

Everything is working geart so far but I can only get up to about 30mph around my house and I don’t want to take it out on the main roads because the car is not street legal and the last thing I need is a ticket for driving with no inspection, no insurance and no plates on the car. I will be heading up to the dyno this weekend to run it hard for several pulls and I will let you know how that goes next week. The real test will be in a few weeks at the race track and I will do a 2nd follow up at that time also. I hope it all holds up, I really don't want to pull that thing back out again
