Another turbocharged S2000 close to completion

s2k's look so norti with a FMIC

cheers for the info

just another question, how to u upgrade a diff?
is the 4.1:1 and 4.4:1 like a final gear ratio or something

i've heard u can replace the s2k diff with one from a skyline, but u have to modify the drivetrain :s

cheers

They offered to recondition my bov free of charge, just freight charge only. It's the fitment that's below my standard; from the workshop that made my manifold, . I will try a skyline gtr bov this weekend.

Elias, the owner of the turbo s2k in syd, warned me about the diff. We were really careful on the dyno and strapped the car. My diff has also been upgraded to 4.44:1 so it's a little bit better than the 4.1:1 stock diff. My car hit full boost at around 4-4.5krpm and vtec at 6krpm. Elias's car hitted boost and vtect at 6krpm all at once. Probably a deadly combination for the diff. Elias has made a few changes recently which should make his car real fast.
BTW was Elias' car strapped to the dyno at all when the diff terminated?

I deliberately chose this turbo rather than the cheaper BB Garrett for it's linear power delivery rather than the on/off behaviour of the BB. The sudden on/off power will break traction or the something in the drive train. There is no point having power if you can't deliver it to the ground :). This turbo is not that laggy for it's size. I get 0.8 bar of boost at 3.5krpm on the dyno. It's a bit later than that now with the boost leak but hopefully this will be rectified on the weekend.

Sorry, I haven't got any dyno sheet yet as the car is not yet finalised. I will post a dyno printout later.....hopefully with a time slip next weekend. I hope I can drive the car home with mid 12 sec.

He blew it off the dyno. on the road, as soon as he hit boost/vtec in 1st gear.

i know this sounds bad.. but i sort of cant wait til my diff blows, gives me a reason to finally upgrade it :/

4.4:1 ratio conversion was only a gear and pinion change. The change in ratio might have reduce the load on the "very weak aluminium" diff.
I think skyline will be my next option depending on the cost.

Bugger, Adelaide International Raceway website stated that they won't allow convertible without a roll bar to enter the Drag National. Does anyone know if the roll hoops on the s2k is acceptable? Will give them a call during business hour today....I hope that they do.

what's the cost of a setup like yours?
You don't have to answer if you don't want to =)
assuming well over 10k?

Unfortunately everything is custom when it comes to the s2k as the market is not that big yet for RHD especially. So it's more than 10k :P

Just a head up.
Great service from GFB.
I sent them the BOV on Wednesday afternoon and got it back yesterday.

man, i think i fell in love! gorgeous what more can u want rwd vtec turbo! Oh My..

9krpm... heard your car was at the drags on sunday at AIR? how did you go?

Will this car now take crown of Australia's Fastest Honda? It better!
