could somone tell me what is the maximum bhp my gearbox can withstand its a CTS stage two? & how much can a stage 2+ withstand as its going to cost me another £795 + vat for the upgrade of shotpeend gears, i havnt built the engine yet but its going to be a 16v zetec turbo, but i'd rather have the reliability from the outset... cheers

 

i broke a cts stage two on my old engine running 300bhp and nitrous, why so much for the upgrade

 

Turboboss, what do you use now? MTX?

 

nah same box i just upgraded to the stage two plus but i will have to see bernie soon i need to drop my final drive 3.82 no good to me..

 

that was the price i got given by cts but i think it was off the top of the blokes head, how much do you reckon it would cost for the upgrade?

 

795 for shotpeened gear set,it cost me 55+vat to have mine done,hell of a diffrence

 

where did you get them from? surely not CTS

 

Hi guys, let me explain the pricing.
An upgrade from stage 2 to stage 2+ is priced at £795.00+VAT.
On a stage 2+ upgrade, the build is treated as if it were a fresh build, with all new bearings, any rebuilder parts, plus a gearset that we have shot peened and polished. But you are effectively supplying the Quaife ATB diff that already belongs to you.
The value that we apply to that diff is £400.00, which is the difference in price between a stage 1 box (£495.00) and a stage 2 box (£895.00) with the difference between the two boxes being the Quaife diff.
You might notice that at £400.00, that is quite a discount over Quaife's £475.00 retail, but I buy in bulk and pass some of that discount on.
So, the upgrade works out to be a stage 2+ box at £1195.00 minus the £400.00 for your diff which gives the £795.00+VAT.
Hope that explains ok

 

thats perfect bernie, but how much bhp do you reckon the stage two+ can withstand & how much do reckon a stage two can withstand with out going bang

 

What torque figure you aiming at ? Thats just as important as the BHP

 

More so

 

I was gonna go for the stage 2+ box. Doing a zetec build... 300bhp and 320lbft (ish) torque my aim. I thought the stage 2+ box would do the job?!?

 

So effectively a gearbox that costs 1200 quid or there abouts is actually worth nothing

good purchase

 

so let me ask is the case then that if u just dont use a diff then its 495?? hoe much do u ned the diff over standard ?

 

i rebuilt my own box mate took all the internals out an took them to an engineers shop in warrington,he does a lot with formular ford,he take your internal to a place in north wales called british aerospace were they build planes and all that etc an they do the shot peening and he simpley polishes the gear set and crown wheel for you ,think it cost 55+vat,then i took the viscous diff to bara motor sport in bromsgrove and he rebuilt the diff and put a higher viscousity fluid in it ,this was tighten to 120nm,very tight diff that cost 300 hope this helps

 

get the standard lsd rebuilt works well

 

I broke a stg2 with 250bhp/290lbft

the stg2+ is unbroken by anyone, i would never ever by anything less than the 2+ nowadays
