ScoobySounds Posted April 17, 2008 Share Posted April 17, 2008 Hi All, after goosing my 3rd gear at knockhill a while ago i've been educating myself about how best to proceed, but after having spoken to lots and lots of people I'm left a little confused and worried. so wanted to air my confusion here for opinions.. options thus. 1. rebuild my existing wrx gearbox pros - it will be built by an expert and i know it will be at its best - cheapish, but don't know how much parts would be cons - next time I go on a track its going to get stripped again. 2. get a 2nd hand wrx box or sti box; (sti box is negligably stronger) pros - cheapest option cons - next time I go on a track it will strip. 3. upgrade to a 6 speed pros - good strong box, perhaps better resale on car!? cons - contant anoyance changing gear all the time, heavy and costly. 4. upgrade to ppg 5 speed pros - everyone says this is the best option, stregnth, ratios etc cons - completely unaffordable at £2500 I hope some genius here who can shed hope for a good affordable solution. I really miss my scoob sitting all sorry for itself. Link to comment
thewelsho Posted April 17, 2008 Share Posted April 17, 2008 I feel your pain my friend and although I got my standard box re-built to standard spec, it is as you say, not the best option. I suppose you could go down that route and never track the car again; that is what I'm supposed to be doing (yeah right). Also the PPG price of 2.5k is parts only, then you'd be another few hunner notes on top of that for rebiulding your existing box. I'm sure you'd likely be over 3 grand for that. Sadly there is no real easy or cheap solution. How about trying to get a 2nd hand replacement and use it until you can save enough for something a bit stronger. Or, use the money that you'd spend on the cheap box toward the PPG kit and put the rest on your CC? My hope is to pick up a 6-speed STi box at some point, but I'll have to change the diffs and prop-shafs; or to go down the PPG route. Either way, its not going to happen any time soon.

sti pretender Posted April 17, 2008 Share Posted April 17, 2008 Think it all depends what you plan for the future. If your going big power then the best box possible. If it your not planning much I would probably go for a 2nd hand STI. Not an expert on this just don't see the point in spending more than you need. Link to comment

If your going big power then the best box possible. If it your not planning much I would probably go for a 2nd hand STI.Not an expert on this just don't see the point in spending more than you need. I agree, but i've been told that if I just go for a wrx box or an sti box (essentially only a few % difference strength-wise) that it is very likely to happen again, and i'll be back to where I am now. I think for the future I would like to use it for track days quite a bit! that was only my first and don't want to give up so early. as for power, well i'm not planning anything ridiculous.. its 310ponies at the mo and quite happy with them. just handling upgrades planned. John - what was your decision in the end are you keeping the scoob????!??? Link to comment
thewelsho Posted April 17, 2008 Share Posted April 17, 2008 John - what was your decision in the end are you keeping the scoob????!??? Oh yes! Got some tints done on the rears and got measured up for new graphics :thumup: Hopefully they will be fitted in a couple of weeks. Link to comment
ScoobySounds Posted April 17, 2008 Author Share Posted April 17, 2008 Ace man good to hear - and i've just seen the tints, looks v good. I had tints on my last scoob and have been trying to stay off em this time.. although mirrored ones tickle me sometimes. I'll look forward to seeing your new graphics! Link to comment
fai17 Posted April 18, 2008 Share Posted April 18, 2008 With 310bhp i think the standard STI gearbox should cope with it... You need to look at why your original box let go...was it low in oil? was it needing serviced? I don't think it the power that killed it. Link to comment
cullenmin Posted April 18, 2008 Share Posted April 18, 2008 Anyone know the best way to set about the PPG route. I have been on the Zen website, apart from going down there to have the PPG done, what way is best? Rich Link to comment
colin_ross Posted April 18, 2008 Share Posted April 18, 2008 (edited) At 310 a good phase 2 still box should take the abuse no problem. Early phase 1 sti boxes are marginally stronger than the equivalent wrx but once you move to version 5/6 the differences are far far greater. They have less teeth but they are thicker and wider and therefor stronger. I personally ran 416/400 through one and that included big drag launches without a whine or a grumble. PPG is another story. If you want a new one you're best bet is to speak to the main 3 subaru specialists in the UK, API, Zen and Lateral. API and ZEN will build the box for you but Mark at Lateral is a parts supplier only but a damm cheap one once you get to know him like I have. If you go down this route you wave a few options open to you, straight cut or semi, dog or syncro, standard fork or billet. You then also have to decide on your diff options but you can leave them be if your happy with your current setup. Straight cut is louder but stronger and semi is almost as quiet as standard but slightly less strong. Syncro is the only real option for a road car, dog is ultra hardcore but will let you do clutchless changes but will require constant rebuilds. I should also point out that the PPG kit only has 1st - 4th gears, you carry over your original 5th or you can source a UK 5th if you want to lengthen an sti one. The selector forks can be carried over from your original box but I wouldn't bother. Do it once and do it right and pay for the billet ones to compliment the rest of the kit. So, PPG will stand you at well over £3k in parts + building + gear oil + fitting + 5th gear (maybe) or you can do like I do and hunt down a secondhand one. If your original box is still working you'll have that to sell to help recover some of the costs. Edited April 18, 2008 by Playsatan2 Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 Peter, yeah I first thought it was low on oil then the greersport chap checked it himself said it was absolutely fine - what was his name again peter, you remember when your were gathered round the skyline at kh? (son-of-greer) I'm gonna ring them today. and it shouldn't've needed a service cos it had a full service at hypertech about a month or two previous. maybe it was my driving that killed it.. I do like to time my gearchanges so they jolt rather than mesh nicely (thats too slow!! ) - which doesn't feel kind to it. Palysatan, Thanks for the info, best news i've heard for ages about this. gonna look into it.. It means I've come full circle! having first been advised from mr. forrest about getting a sti5/6 box! shoud've just listened in the first place! Today I will be celabrating that I don't need PPG! What does everyone else run? box/power/torque ? Link to comment
colin_ross Posted April 18, 2008 Share Posted April 18, 2008 Have a look at the code on the top of your box, is it a 752 or a 754? Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 does the box have to be out the car to see that number or can I look under the bonnet? Link to comment
colin_ross Posted April 18, 2008 Share Posted April 18, 2008 Pop the bonnet and look at the top of the box where it meets the engine. You're looking for a sticky label. Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 cool i'll go down and do that in a wee bit. btw - I've just spoken to roger clark motorsport on the phone to see if they have sti 5/6 boxes, and he tittered under his breath when I suggested that they were stronger than wrx ones. he said they're all the same!?

Does that mean he doesn't have any then Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 hehe na he's got two of these freshly built ty754vn2aa boxes for 650 + vat. hmm.. if I could fit it myself then maybe. Link to comment
braveheart Posted April 18, 2008 Share Posted April 18, 2008 Does that mean he doesn't have any then Hope you get it sorted mate try and fone Dastek in dalgety bay mate they might have a gear box there ....its a stab in the dark Tel no..0845 345 4045 just said Chris with the white Sti thought you might have one...

colin_ross Posted April 18, 2008 Share Posted April 18, 2008 hehena he's got two of these freshly built ty754vn2aa boxes for 650 + vat. That's what I thought. If he'd some of the phase 2's for sale I doubt he's have said the same. Do a search here or on snet to see the differences. Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 oh - are those ones not the right ones? how will I know a phase 2 box? can you tell from the TY number? and cheers chris, i rang dastek but unfortunately they don't have any in. Link to comment
ScoobySounds Posted April 18, 2008 Author Share Posted April 18, 2008 and I rang greers but they'd need to know if the ratio is 39 or 41 before they could advise. checking the ratio seems over my head. Link to comment
tidgy Posted April 18, 2008 Share Posted April 18, 2008 its not power that kilsl box's its the torque. i stripped my 3rd gear at 260bhp 280ftlb, might have been getting a bit long in the tooth, but i was giving it death on the isle of mann tt course if you doing alot of track days then ppg gea***t might be the best option. its not the power that will kill it on track, its the heavy handling, and the ocasional missed gear change will spit out the cogs no problem, so paying more now might be a saving in the long run. as sugested your options are recon the box - prob wont last 6 speed - dicks around with the ratios, still not gonna get change from best part of 2 grand but will be up to the job 5 or 6 speed ppg, straight or helical cut - def do the job and strong enough for what ever abuse you wanna give it, but will set you back best part of 3.5 for a the kit (2k) building, and uprated clutch plus fitting. the sti box's are stronger than the uk box's, but not by much, as far as im aware the type r box's are just sti box's with dccd so wont be a big improvment. all in all i think if your doing track days then you need to throw some dollar at it Link to comment

I was almost entertaining the idea and expense of the 6 speed, but seems like so many uncertainties in getting parts and them being compatible that i'd prefer a simpler route IF there's enough people who say that 310 will be fine with it.
