As you seem one of the most knowledgable individuals on the site and are independent, if I get my car uprated to about 360 bhp and 360lbs of torque, do you think that the diff will last out if I come along to some of those quarter mile sessions.
After reading about Mike Rainbirds problems, and being told about how fragile the diffs are on Subaru's- cos they are small and you cant get a big one in the available space? I wonder if its worth it -if I end up forking out loads of subsequent money on repairs
If I dont bother with track days, will the diff be able to take normal driving? - Sti's seems OK but you never know if they are talking a pack of lies half the time
Thanks

Hi...
Thanks for the compliment..but I am far from the most knowledgable...but I am independant.. :}
The scoob is limited to a 6" diff.... I think you will find the rally cars only run a 6" one too
Apart from the gearbox internals/clutch... the diffs are the next weakest link...
A track day is less harsh on the diff than 1/4 drags (although it does depend on the driver) and getting the car on two wheels
You never stated what car you have ? The STI's have "uprated" diffs over the UK/OZ cars..
The STI ones will take that power just... but you will be reducing their life... by how much I cant say.. that depends on you and what abuse you give the car...
Thats a hefty amount of torque with that BHP.... sounds like a Dave Morgan prepped engine ? What mods are you having done ?
Diff repairs arent expensive.. but are tricky to do..but once you have done one.. they arent too bad..
Define normal driving ? motorway cruising.. or traffic light starts ? You cant give definate life spans... but one thing will be sure... they wont last aslong as a standard car (due to the fact that you will be making the most of the torque and power)

Thanks for the reply
My car an Sti 5 4 door salloon, which turned out OK as STI have had no end of gearbox warranty claims on the sti 5 type R, due to losing 5th gear.
yep, I am thinking of having the Interpro - Dave Morgan prepped car.
As far as teh mods go its too complex for me to understand, but includes:
Uprated:
pistons
liners
conrods
conrod bolters
crank
uprated dump valve
engine block or whatever taken out and sent off to be worked on - whatever that means
other work including anti det rings
Mongoose full stainless exhaust (as numerous swaps by Interpro - (and Autotechnica - Yorkshire confirmed)showed this to give best low down torque gain)
Specially designed ECU, as none of the after market replacements are any good - due to them not havign a fat enough processor - leading to problems
a seriously sucking green dome shaped air filter
)(Only further restriction then is Turbo. May put on oil cooler and insulate some of engine to minimise heat build up. May also put on a front mounted intercooler)
Conversion can take up to 36psi, but Dave reckons 1.8 bar is more realistic (26 psi) to prolong engine life.
Dave said I shouls give him some pre signed checks, and ensure my overdraft limit was sufficient. Work should cost around £6k, so not that much really.
Had to have it done though - car feels too slow.
I'll probably change to 17 inch wheels in the next few months also,plus the sti brakes fade bad on repeated heavy braking- i.e there a bit naff, so someting will have to be done there also.
Never taken car on the track, but intend to.. soon.
Normal driving defined as ' not getting the attention of the Police' - hence nothing too stupid off the line at lights.

Sounds like fun!!
Thats is basically what I was gonna do...
Mark in Scotland is running 2bar... and knackers his diffs... but he does give them a hell of a lot of abuse!! lol
I would strongly suggest an Oil cooler... and transmission cooler...
What turbo are you using ?
A front mount will introduce lag.. but the trick is to match the turbo to compensate..
The green filter thingy is a HKS mega flow..
I assume Dave has actually bought the kit in japan... and is probably using some like Jun or Zero Speed... I cant see him designing his own crank and cams...
Chances are he is porting the head slightly.... are machining it out if he is fitting bigger cams...
You will definately need new rods, bolts, pistons and liners for that boost.. and an uprate steel crank!

Hi Steve
£6k is a good price. Parts alone would set you back in the region of £3k and a bench map session is about £1,500.
So, sounds like you have a good deal there!
Let us know how you get on.
Kind regards
Ben

Daz mate...
If he is running a charge cooler... theres no point (no where to fit) having a water spray...
J.
ps - 6K is a good price...especially if he is replacing all the parts you have listed...

Will be running standard tubo for moment
Reason for price is that he's selling at pretty much cost price. Drumming up demand in the initial period.
yep an uprated steel crank!
as for scooby kit - not sure - dont really like their product range (no offence to them)
especially the alloys. Will ask Dave to comment , then I'll ring Billy, Kevin and Barry at Well Lane and see what they think
Daves currently getting a new ecu sorted out which will arrive i a couple of weeks - once thats sorted then the car can go in (if 2 weeks wait is anything like Power engineering's 2 weeks - the car wont be in until 2002!)
Dave was pessimistic about future new car sales - talking about having to live abroad in the country your importing the car in for 1 year for it to class as a personal import - for this reason and the crap exchange rate he reckons the current imports should start to rocket in price?

With this sort of power what do you intend to do to the tranmission ,I have done a lot less mods to mine and already in a few miles ran into difficultys with the clutch ,I have been reading also how weak the diffs and gearbox are with such mad modifications be careful that the upgrade does not cost you more ALOT more in the long run.

This is something I was thinking about - Mark in Glasgow (480bhp monster) reckons the clutch and gearbox should take up to 360/360
Wont be anything new - after a first stage mod of my escort cossie the clutch lasted all of 2500 miles - new one then went 8000 miles later!

No problem - I'll get you '**** scared' (on a private road officer)
My bank balance is going to be a bit lighter (or rather looking dire) in a couple of months. On top of that the girlfriend wants two weeks all inclusive in St Lucia over xmas and the millenium! - that'll cost muggins as well!

Steve M,
360bhp/360ftlb sounds like a very impressive conversion.
Quick question, who are you writing the cheques for, Interpro Automotive, Interpro Engineering or Interpro Somethingelsebynow ?

Watchya..
Build an engine for me ? Now let me think about that...
Gonna bring the bits over with you, when you come to visit me ?
Forget the 15.. its a dustbin.. it will takes years to respond... lol
Let me think... stick to two litre... but I'm still considering 2.2... but it will limit my top end boost.... go for the 6Kg flywheel... 4.5 is too light...
USA Pistons ? JE by any chance ?
I prefer Cosworth
Stainless valves...mmmmm
I'll order my uprate transmission now then...
I'll take you around... I'll sort out some accomodation if you like... Pop in at Prodrive...and a few other places...
