Dave,
I REALLY think you should try the two different 6 speed boxes before you buy anything. If you still prefer the UK version then I would be willing to sell mine providing I can get the longer geared version at similar(ish) money It has 16K on the clock and I thoroughly disliked it's close ratios. I've read what you said earlier and if you're always going to "drive" the car then it may be fine but even with the 2.5's increased torque it still seemed to want gears thrown at it too frequently for my liking. Sorry I can't offer to let you try it at the moment because, as usual, it's in bits & spread around the countryside
Cheers,
Callum

 

Pmsl, thanks Callum.

Will get onto Subaru asap...for them to tell me i can't get a shot, as i'm too young.

 

im running 1.9bar on a hybrid twin scroll and mine still doesnt feel like it has 400lbft

 

I've peaked mine at 1.9 bar as well, ditto, although we might be getting nearer. I felt that was a bit high for stock Evo rods (pistons are tough though) so I have it at 1.8 peak at present. Probably makes no difference, but psychologically it doesn't feel like 2.0 bar. For this week anyway

 

john mine is on a built engine so im not bothered about the rods but cant go higher as my injectors are maxed out !!!

 

You could go higher midrange then

 

I got 499 ft lbs at ProSport on my original big power 2 litre but discounted the result because with race fuel on other rollers it was around 460 ft/lbs.

 

Interested in your findings for this one Dave. I've no idea how much torque my motor is chucking out but it's a lot more now than on my old 20g spec. That was enough to do 2 syncros and blow the syncro hub on 5th into a million pieces.

All I know at this point is that I'm going to have to look for a more long term solution (6 spead or new gearset) as it's not going to last long at my current spec, my stage 3 mods will probably kill it whilst being mapped.

 

Lol, i know. Just always thought there was a stage missing inbetween a Subaru standard box and a gearkit, but hopefully we can get some more light shed on the subject, that could help decide if indeed a kit is needed...though i reckon if you get a larger turbo, that is what you'll be needing.

 

You may be okay with a STi V5/6 box - some people seem to get away with using them and other break them with little over 300ft/lbs torque

You should be okay with a PPG - far stronger than the above but still not unbreakable.

How about a Forrester STi 6 Speed - somebody mentioned this when I was considering my options....longer ratios and stil strong? Has anybody actually fitted one of these?

 

bob' they are like rocking horse pooh, I was offered one around a year or two ago and it was around 3 - 4k... no thanks.. now they have changed the ratio's in the other scoobs, then in 6 months they may be more accessible.

David

 

drb5,

I've ran 2.2bar for the last 3 years on a STi5 box (type R) with no problems - however this is on a 2lt with non gearbox threatening lag. 2.5ltr would probably be a different story.

What do you base that on David?

 

6 years of reading peoples views and 6 years experience of playing with tuned scoobs.

I think for the money they arent the best choice, yeah granted they blow air..

Bit like some people rate the APS SR turbos.. some dont.

Im not putting specifics, Id have to go try and find the threads and I cant be arsed, Id just go with a 20g or the TD06 mark does.

But for 2.5, bolt on my choice would be a Lateral MD321T

David

 

But I've spent 7 years reading peoples views and 7 years playing with tuned scoobs

Both the the bolt-on Red and Green have bettered your times on the quarter (on heavy weight newage scoobs with 6 speeds) and they are less then half the price of a rotated gt35r set up (and blow less air!). For the money they are an excellent choice - I guess you've been reading/listening to the wrong views

Agree with APS turbos being bags of carp. Funny when you think they are all based on GT chra's. hmmm

I guess you don't know how long FP have been producing tdo5/tdo6 mhi/garrett hybrids then? Where do you think Mark got the idea for the tdo6/garrett from?

Is that the one that recently produced 60lbft less then the quoted figure?... hmmm that'll save drb5's gearbox then

 

I put a six speed on my RB5 two years ago.It was running circa 350/350 and for me, it made the car.

The gearbox was from a UK 03 STI. Although I have had it rebuilt recently due to some syncro problems. P1$$ easy to fit to a UK classic too.

I have taken it of the RB5 and put it onto another UK classic. All thats needed, providing its a uk car its going on and the box is from a UK spec (which I would advise) is a propshaft from an automatic as its 60mm shorter.

If you start messing around with jap spec boxes or cars you then get into drive shaft and different rear diff territory.
Where abouts are you based? If you're around yorks anywhere you're welcome to come for a spin in mine. Make it after sunday though as the 740's and the apexi power FC go on then

Daz

 

The one that produced 60lbft less than a quoted figure.. the 'one'


I dont really care who's bettered my times I dont really give a **** about that, Ive manged to keep my heads on my engine longer than most, and Ive not had one head gasket failure.. thats all irrelevant though.

See you agree with the APS turbos being crap, however some people in the states love them..

Back to 1/4 mile times, I aint comparing US WHP to UK HP, nor am I comparing down hill foreign tracks to up hill uk tracks such as elvington..

I make a point of trying to allways run in the same lane on the same day, and compare times and datalogs from that, For example I dont compare times between york raceway (more like the pod) and elvington.

And you say about the rotated 35r Setup.. Its not quite what I have, but how much do you think I have in my rotated setup, bearing in mind I have been running a rotated turbo since 2001/2002

David

 

Daz, He's in scotland or thereabouts

 

Stick your finger in the air, and guess. Thats how you will find a suitable gearbox, or maybe you wont.

Its that random IMO. There are too many different parameters to peoples driving style that can contribute or not to a gearbox failure.

People saying they have this that and the other torque figure, dont explain where it hits and for how long, nor do they state whether they use that torque, or just stay in the BHP zone.

The exact same can be said for clutches IMO.

Steven

 

Lol at David. Yep, about 20 miles north of Glasgow, so a wee trek.

I know what your saying Steven, but what your explaining is really all that seems to be able told. I know there will never be a difinitive answer, but it does sound very chancy. Even Bob' saying you "should" be ok with a PPG kit....who want's to know it "should" be ok when handing over 3k?

If placing the 3 gearbox types on a list of strongest, number 1 being the strongest, would it look like this..?(not taking into account driver and all being brand new items)
1.PPG or similar kit
2.STi 6 speeder
3.STi 5 speeder

Does anyone know of someone who has taken a 6 speeder to 500+hp without problems? What's Alan Bell running just now?

 

David Wallis, well over 500, just a synchro problem.

Alan Bell Mid 400's, just a synchro problem.

Ranking IMO

1. Dog kit for 6 speed
2. Dog kit for 5 speed
3. PPG or similar for 5 speed
4. STI 6 Speed


10. 5 Speed

 

ill let you know what my 5 speed takes before it goes bang soon 10th Steven? bit generous isnt it?

 

And steven has driven my car and not killed the 6spd.. having said that I think I should charge him for the syncros!!!

David

 

9. Cheese

 

PMSL!

Now we're getting closer to peoples opinions and problems.
So the 6 speed syncros...are they any stronger than the 5 speed's?

 

David.

Don't get your knickers in a twist, the point Hyperluxa was making is that your casual, arbitrary, unsubstantiated and in essence provably incorrect dig at Forced Performance products is miles off the mark.


People who may have only been on here a year, may be influenced by what you have implied and then miss out on some provably fantastic kit, based simply on an off the cuff an "uninformed" comment like that.

I know for a fact that Hyperluxa knows intimately, and in a degree of depth that would simply stun you what he is talking about. Even I wouldn't argue with him on this point, (and that's saying something)

There is masses of evidence to show FP as being at the top of the pile in their area and it's the primary reason that I am an Agent for FP they are routinely copied by other manufacurers and for very good reason.


Mike.

 

i can tell you myself if you aint in a hurry as im not putting my garret on till after my holidays

 

Looking forward to hearing about it Steve!


Mike, anywhere in particular, i can find some tried and tested reviews? NASIOC i presume?

 

they are all over nasioc

 

Cheers Neilo. Hard work trying to find them, but i got there. Red seems a bit overkill for me/my box , so the green may suit, but will it be ported enough to sort out creep?

Back to the gearboxes though, who gets a steady run of secondhand 6 speeders?

 

euroauto salvage !! but make sure you ask for everything you need or you may get stitched getting the bits from other places !!!! but having a car mapped on an RA 5 speed then switching to a 6 speed gearbox , the 6 speed was a total dissapointment and it was even a jap one with similar ratios , the uprated gearset would win hands down IMHO
