6 speed gear box

[sweetcal66]

Looking at getting a 6 speed gear box for my 8 gsr.

Just wondered if other people have done it what the pro's and cons are, what I will actually need other than the gear box obviously.

Cheers

The 6 speed box is weaker! All depends what power your running or what power you plan on running....if your going for big power id stick with the 5 speed

No worries answer I wanted save money for to buy other parts

 

[andyw08]

Ha ha its the gsr yours isnt it? What mods have you done up to now?

 

[sweetcal66]

Aye gsr it's got blistien coilovers, aem short ram intake, forge blow off, Megan manifold elbow and down pipe, walbro fuel pump, adjustable cam pulleys, waiting on light weight pulleys for water pump alternator and crank, apexi fc ecu, once that arrives will be getting mapped at evo tune to see what power I will get out of money

Has it still got gsr cams and turbo on?? You want to uprate them... iv just put hks 272/272 cams in, piper valve spring and an MR turbo with a 10.5 hotside on and had it mapped again by simon norton.......with pops and bangs hehehe

 

[sweetcal66]

No not yet that's next on the list where you get your cams from?

 

[sweetcal66]

I was going to go with cosworth 272/272

 

[andyw08]

I got mine from america (NY) and was recomended to get kelford 272/272s or hks 272/272s. I may be wrong but im sure cosworth cams are fairly aggressive (lumpy tick over)

 

[sweetcal66]

No worries I'll stay way from them then, what about gsc's 268/268, how much you pay for your hks if you dont mind me asking? Cheers

 

[andyw08]

Just looked then....the cosworth m2's have 11mm lift on the intake and exhaust...the HKS Have 10.8mm on the intake and 10.2mm on the exhaust, the GSC's are good cams aswell, gsc s1's have 11mm intake and 10.5mm. I paid about £300 including import tax and delivery but they were second hand and had to get valve springs aswell

I've just bought gsc's 268/268 brand new for 380 and I hopefully use stock retainers and springs for now
