First up fitting the hydro gearbox. It's an S4C fully rebuilt with mfactory carbon syncros, 5.1 final drive and an mfactor plate LSD. it was previously fitted to the Tegiwa CRX Race car
work begins
First up remove the ultra rare (maybe) mugen centre caps to slacken the drive shaft nuts. these came off without much of a fight, infact everything did really. i guess thats a benefit of the engine only being fitted a couple of years ago
jacked up and it has an underbrace fitted. it's been taking a bit of a beating but protecting my 5zigen manifold atleast which doesn't have a mark on it.
removed the front cross member as this will need to be modified and the manifold
battery tray out and got everything ready to come out on the top side
this mount was chopped off the cross member to make way for the hydro actuator
Box off without too much drama
hydro box
Decided to give it a lick of paint - old vs new
at this point i thought i would fit my Quaife steering rack which also came from the Tegiwa CRX
I'm using Uprated Innovative mounts all round to compensate for losing the front engine mount. Fitted the Innovative to the new subframe and fitted up the rack
Removed the rear bracket. 2 of the bolts are thicker on the hydro box - m14 rather than m12. Picked a couple of bolts up from my local bolt shop and enlarged the holes in the bracket to suit
fitted the new clutch cable. I'm using a longer Honda Concerto cable which is the perfect length for the new system
bought a new exedy hydro clutch kit
removed the passenger side lower cover which gave me access to the crank pulley. used my crank pulley tool which i bought years and years ago to lock the crank and fit the new clutch and flywheel
ITR flywheel off - Fidanza flywheel on. couldn't believe how much lighter the fidanza is!
fitted with a new OEM spigot bearing
clutch on
Box on and hydro actuator on with innovative mount
the box was initially tight up against the side of the engine bay - a bit of bending with a crow bar and there's a couple of mm clearance all round
the mounts are so stiff that it was a bit of a mission to get them all lined up, but got there eventually and all the bolts in
new bolts in the rear bracket
new shafts in
first problem - the o2 sensor fouls on the innovative bracket. Had to get a new boss welded in further up the manifold and blanked the old one off.
Custom exhaust has a good size bore!
All finished! you can see here where the front mount bracket had to be cut off the cross member.
refitted the steering rack gubbins in the footwell
centered the steering wheel on the rack and took it to Andy Turner motorsport for a full alignment. the result
So the verdict!
Well first up - the car has lost it's road manners. The engine mounts are HARD and the car shakes at idle. The steering is much stiffer with the new rack and the diff kicks like a mule when slow maneuvering. It also sits at 4600 RPM at 70mph in 5th now. Do I care about any of that..........not one bit!
The gearbox feels amazing. The shift action is so much nicer and no more crunches what so ever. The car is also SO MUCH quicker! It flys through the gears with the 5.1 final drive and light flywheel, it revs HARD in VTEC to 9000+ RPM, i'm staggered at the difference. The Diff is seriously aggressive and a real handful on the road, it feels like a completely different car. It's going to take some time to learn to use it properly, will be getting on track next month and I can't wait to see what it will do!
a few pics from the last track day at blyton to finish off!
. I wasn't sure about the brand but the civic cup cars are using them so mist be alright. Whipped off my bilstein and eibach setup 
.
. I also asked for a bit of toe out on the front and a bit of toe in on the rear, so we'll see how that works out on track.
