It cost alot but in fairness its been the best thing i've done to the car. It totally transformed it! I honestly think most people over look the gearbox and spend their time and money on the engine. I wish i'd done my box first, then probably spent less trying to get more power. The box makes the best use of the power you already have. Its obviously not really suited as a daily driver being so low geared, but it certainly goes well on track! I can basically lap my local circuits without dropping out of the power band now. Its only downside is the fuel consumption isn't great. The Mfactory website has an online gear calculator which i used to get the spec on my gearbox. Its fairly accurate and easy to use ( even i managed )
I used mfactory for my box. Its a y21 on a b16. I was lucky enought to be part of a group deal a while ago so we got a decent discount and cheaper shipping. I bought the close ratio 3rd, 4th, 5th. The 4.928 final drive, Helical lsd, full set of bearings, full set of carbon synchros, and a drain plug I used Lings Honda for all new seals etc... and i bought the Torco mtf from Nimbus morotsport as Mfactory can't ship it. ( liquid obviously ) I think i did a write up about it in my build in the 5th gen section. There are some short videos in the which should show you how it goes through the gears. The guy i dealt with at Mfactory was named Stephen ( i wouldn't know if hes still there, but he was very helpful )
Leo, Where abouts are you based? I have an sir with the bronze screen. I sold all my sides and rear glass on here a while ago. The screen has a few small chips and a couple of repairs. I could sell it but would need a replacement. I'm not bothered on tints as its a track car. Let me know if i can help.
25 front and 27 rear cold ? That would give you mid to high 30s when hot. Front left maybe slightly higher due to the circuit. Was the second tyre from top the front left? I would guess it was due to wear on the centre. Could be getting the pressures too high on them. I run 28psi all round when hot.
