I'm after a 6 speed set up, preferably Dccd to go into my 95 Sti type Ra.

So
gearbox, cradle, selector, prop shaft and matching rear r180 diff, rear shafts and hubs.

What you got?

Def need Dccd step back if you didn't. What power you looking to run joe?

joe v3sti

iTrader: (8)

Yeah I want the Dccd, to be honest mate I'm not running stupid power, realistically 400 -450 but I plan on using it, so haven't really got a choice but to go 6speed, running the 2.5 it's gonna be the torque that's a killer

sonic93

2.5 def a 6 speed needed. 400 leave your Dccd see what happens I had mine in at 402 for year and half and year before at 380.
What turbo you going?

joe v3sti

iTrader: (8)

Don't get me wrong it may be ok fort a very short while, but my problem is knowing my luck it will go at the most inconvenient possible! Causing me an issue. I'm not in no rush to get a box, it's a just a case if seeing what's out there and putting some feelers out. If I have to I'll leave mine in place whilst I run my new engine in.

Turbo wise I'm in 2 minds weather to go for one of Andy's billet 20g's and don't be too greedy. Or go for something like and sc46 and peg it at 450.
I've heard really good things about the 20g on a 2.5

What turbo are you planning on using on your new build? Obviously your going to be due a transmission upgrade too.

Just to fling this in my 20g is perfect on my 2.5 forged build, there is power available the whole way through the rev range and it pulls like a train

mines at 400 and all seems good

Sounds good, is this in a classic or newage? 5 or 6 speed?

Cheers joe

Kirk1967

there someone on here selling one

In a classic type r mate, only on the standard 5 speed, the short ratio one. I love the gearbox and the feeling of the quick shifts, its like you are never off the headrest but it does worry me that if I go over the 400 mark im going to need something stronger so I may just stay around the 380/390 mark because it seems to be coping ok so far.

A sc42 also be a good choice. I'm just gonna max my sc40 on meth. Yep a jdm ratio Dccd .

joe v3sti

iTrader: (8)

6 speed jdm Dccd? You jammy sod. Like you say you should make the most of your sc40 splash of meth and happy days. All this on your built 2.1?

Hi Joe

If you will go down the road with New age DCCD,then you will need to run aftermarket DCCD controller like is MAPDCCD,Neetronics DCCD Controller or if yours ECU can control DCCD then,ECU

New Age DCCD using Yaw sensors,ABS plus lateral G- sensors etc and Classic GC8 is different to this

Technically you can use yours transfer case with PPG and then you will have PPG with DCCD

Am also getting a 6 speed fitted to my 99 RA next week from a WR1. Looking forward to using the torque of the 2.5 as well.

Hey Jura.
I didn't realize that I would need to run an aftermarket Dccd controller? I was under the impression that with my car already having Dccd that there would not be an issue?

I am tempted with ppg as Ithink it would be a little more in keeping the with originality of the car. Also it weighs a fair bit less.

ken-sti

Hi lads, I'm in process of doing this switch aswell but I thought you need to change the r180 diff aswell to match ratios of gearbox?

jura11

Hi Joe

Yours OE DCCD controller not sure if will be good for JDM/UK DCCD box,yours car have DCCD controller,but he is not using above mentioned sensors like JDM DCCD

Best will be speak with Alyn@AS Performance or David@APi,Paul@Zen and many others about the best way how to do

PPG,depends on the target,we run at 555.5bhp without the issue PPG,still on the WRX driveshafts and WRX rear diff

Jura

d.kenny

iv looked into this

im 99% sure the diff on a 6 speed dccd works exactly the same as a 5 speed dccd and so connect the 6 speed up as per the 5 speed and the dccd will work exactly the same

the yaw control and intelligent settings are controlled by g sensors etc which just adjust the diff via the ecu and not the thumbwheel

it will work on your standard ecu!

jura11

iTrader: (7)

Agree on that,will be plug and play,but not Auto function which is available on New age DCCD

After some thought I really need to consider which of the 6 speeds will suit my needs best,
A jdm 6 speed may be a bit too short for my 2.5, surely I won't be making the most out of the added torque of the 2.5 whith the need to shift earlier.
A uk 6 speed is a lot easier to come by over the jdm. Maybe with it being longer I can take advantage of the extra torque.

Anyone got any experience of the jdm 6 speed on a 2.5? Running 420 ish

d.kenny

I think he just wants a box to handle more power but not lose the dccd style box he has got at the minute

Obviously the auto function would be nice but iv made a loom to fit a classic style dccd system in my car and that was enough of a headache i therefore would not be keen on trying to retro fit abs sensors and all the associated wiring which in all fairness is taking away the thrill of driving on the edge and knowing i could go backwards into a tree again at any point lol

If i was to want that function and going to that extent and paying as much for the parts as what they are then id be buying myself a wide track or blown up hawk and fitting my 2.1 into that and making the car how it should of been from the factory...late model...low miles...big power...auto dccd!

d.kenny

It depends what you are using the car for pal track or motorway id say

And

If i just wanted a box to handle the power then i think id be going for whatever cones up at the right price and at the right time unless you have an endless pot of money to throw at it!

Hi Joe

Here are gear ratios of the JDM and UK STi

JDM is shorter than UK,I think 5th and 6th is shorter than UK

JDM/EURO 6MT Gear Ratios

1st Gear 3.636
2nd Gear 2.375
3rd Gear 1.761
4th Gear 1.346
5th Gear 1.062 / 0.971
6th Gear 0.842 / 0.756
Reverse Gear 3.545

Second think you will be doing 70mph at 3200rpm on JDM in 6th and on UK you should be doing 70mph at 2500-2800rpm on UK in 6th

Hawkeye 6speed have longest gear ratios,again only in 5th and 6th

JDM DCCD is sometimes hard to get,but usually they will come for sale for more than UK

Really depends as above what you want more track or motorway/fast road.

Personally I prefer longer ratios,its has been useful for us on drag strip,track days or on the fast road/motorway driving,due this we are stick with PPG for such long time,we have opportunity go with 6speed,but we are stick with PPG

Jura

I'm build the car as a fast road car, it will see some track action. Mainly in Germany, I drive my car over there so obviously that's a long motorway stint. I'm attempting to break any records with the car I just don't want to compromise reliability in any way. With that in mind a non Dccd would suffice. It seems a shame to take a car that is fully equipped to run Dccd and run without it, kind of feels like a step backwards. I do like having the Dccd and do use it from time to time. I used it at ring for half a dozen laps, right up to the stage where I scared myself. But I like how you can change the feel of the car.

joe v3sti

iTrader: (8)

Well with my current box v2 Sti Ra it is incredabilly short, 70mph in 5th is around 4100rpm. So either of the 6speeds are a lot more laid back back compared to my current one. I've always liked that fact that's its this short, I think it really adds to the driving experience. It makes the car feel really quick. With 300bhp the car has run a 12.4 on the drag strip which I think is fairly respectable.

My biggest fear with this is I go down the route of a jdm 6speed due to the fact that I like my current sort ratio set up, and it being poorly suited to the 2.5, I don't want to loose out and the extra low down power that ill have added by going 2.5 in the first place.

I've had a look round and due to me have a v2 Sti Ra I can utalize my rear end, ( rear diff, shafts and hubs) the final drive on my current rear diff is compatible with the jdm 6speed box, therefor all I need is the gearbox, selector, linkage and the prop from an automatic. All this makes this option financially a good prospect.

With regards to the uk 6 speed, there seems to be a fair few kicking around, mainly non Dccd. With the factory built 2.5 hawkeyes Subaru obviously felt that longer gear ratios were well suited to the 2.5. Maybe this is something I should take into account. The cheapest way of going about this is uk non Dccd 6 speed.

Decisions decisions.....

Hey Mate, Just saw this post. I used DCCDPro Controller and I think it is worth looking into if you are looking for aftermarket DCCD controller. It was easy to install and works well with no need to change/switch maps and keep track of it. It just works. I am impressed so I thought I let you know.
