As above please can someone confirm if the following will fit in to my hakeye wrx?

And would i need anything else?

6 speed close ratio JDM STi gearbox (TY856WB1CA)
gearbox cradle that bolts it to the car
propshaft,
matching sti rear diff
rear sti thick driveshafts
front sti thick driveshafts
6 speed gear linkage and gearknob

Thanks

As you have the matching rear diff then yes.

But being a JDM box it will be short geared compared to a UK set up, you might find yourself absent mindedly trying to change into 7th gear occasionally.

Good Luck, David APi

Beware of NPS issues, ask David @ API if you need to swap this to avoid the ecu throwing a CEL.

Dave will he not have the same problems I'm having & have to change the front stub shafts, & change the rear hubs for 04 Sti rear hubs to take the thicker shafts, then fit sti rear brakes. as his car is only a WRX and not an STi.

Thanks for the replies so far.

Bez a little off topic but i have the same car as you and looking at your spec i was wondering if you have changed anything engine wise ie pistons and ishow the spec c intake manifold different to wrx one?

APIDavid

iTrader: (4)

The WB1ca, should be the stump shaft type and as such the STI front driveshafts ought to fit. If not then the hawk front shafts will fit with the later front driveshaft seals fitted once the stumps have been pulled out.

AND YES, he will need a 3.9 R160 rear diff as that will be the cheaper option rather than upgrading to STI rear hubs and calipers and so on.

Sorry, got it wrong this time.

David
what is the cheapest way of coverting a wrx hawkeye to a 6 spd and a rough cost

APIDavid

iTrader: (4)

Gosh!! what a question. I expect that by the time it is bought and fitted, around the £3000 mark. But that depends entirely upon how much it costs to buy the conversion ' kit ' in the first place.

The words cheap and 6 speed conversion don't fit in the same sentence together. The technical term is ' Oxymoron ' [ look it up ]

David APi

Bez300

iTrader: (2)

At this point in time My conversion has cost
£2,500.00 for Hawkeye 6 speed DCCD gearbox, drive shafts, prop shaft, rear diff gearnob starter motor craddle,
£370.00 rear STi brembo
£700.00 clutch.
£400.00 DCCD controler.
Rear Sti 04 hubs
Labour

About £4,000.00 + labour That is the Cheapest way I could do it,

(for sale 56 plate corsa 4k,,,, Thats cheap)

Hope this helps,

And thanks Dave for all the help so far, hoping to get mine back this week.

could be a idea to go for a older 6 speed box without DCCD it will save you a chunk of money. not sure how rare these are as RCM have sorted my one out but its an idea. DCCD is only for the strip or rallying.

nice spec bez, what bhp are you running? are you still on the wrx lump ?

Bez300

iTrader: (2)

Thank bud, still running std wrx lump but only running just short of 400 till I get the engine forged, Then will be going for 450 to 500

1. Early boxes have weaker synchros, mine was sixth gear !
2. I have just changed as a 50:50 split is not ideal for "fun".
3. A built PPG or similar will soon eclipse the cost of a six speed set-up.

I just need to work out if I need a "nasty" plated rear diff. for mine next.

If I ever get the thing screwed back together...

P.S. You're getting there young Bez

scoobaru86

iTrader: (1)

I was hoping around half that, I think i may just have to live at 350/360 until i win the lottery

Thanks for the replies, and Bez can't wait to see how it all turns out after its forged, it has to be one of the most powerfull WRX's out there.

PPG are not great for the road tho, loads of the big power RCM builds go for the 6 speeds

coops78

thought you only had 250

Fangoria

iTrader: (1)

Thats assuming you can get a 6 speed - I couldnt so had to get the PPG rebuilt when 5th went.....
then again I have a Forester STI with a 6 speed box and hate it..... its also much heavier
on 350/350 I'd just have the gearbox rebuilt.. in fact much less than 450bhp unless your tracking it then you dont need an uprated box... as long as you dont abuse it with standing starts off the line

I need to be Arnold Swarzennager (ok dodgy spelling) to change the gears on my PPG when it gets hot on the track............ and the helical is noisy and always was

Bez300

iTrader: (2)

I think it will be getting up there as one of the most powerful WRX it would be good to hear of other Hawkeye WRSs that are running big power.

There are plenty STis that are running well over 500.

If your thinking about rebuilding your 5 speed, I have a very trick platted Front diff for it,(£450) the diff has only done 50 miles, and they are over a grand when new. it was in my 5 speed dog dox, (hawkeye) when some of the gears wanted to go solo, and make a run for freedom.
I also have a new Push style clutch with lightweight flywheel that is good for 600bhp for sale,(Hawkeye 5 speed) open to sensible offers.

As far as you only running 350 bhp
Last year in the scoobysprint championship, I got 3rd in modified priveteers when running std TD04 with 300 BHP, but the gearbox, diffs and ASTs made all the differance.

So 350 is still a hell of a lot of power.
Look at your tuned Ford, ****rons,Vaux's there top tuners are only getting 350 to 400,

Bez

Bez300

iTrader: (2)

Did I say 400,
Coops you know I only have 250.

Hi
I would like to fit this same set up to a 98 classic so i take it that i shall have the same problems, you mention extracting the stubs from the gearbox for the front drive shafts then i can use my standard shafts. And can you say what sort of power can the r160 take?
If you have any more information this would be much appreciated plus what are the NPS issues.

Regards
Bwanaiguana

scoobyclinic are selling new ppg boxes which would fit straight into your 5 speed box

heard really good things about them iirc its about 2250 fitted

the money time and effort to get these cars upto and over 400 is crazy think im over 6 grand now and still wanting more

hope this helps

PHEWEEE, go wash your mouth out

Scoobyclinic make their own gearset these days, not PPG and it is a perfect piece of kit, far better than PPG.

We had one and fitted it for a customer a few weeks back and it went together a dream.

It is also cheaper than a PPG set.

Form a queue at Wingerworth.

sorry david thats what i meant

i knew it was a british company that make them for scoobyclinic

my bad for thinking it was a ppg

but on another note its a hell of a lot cheaper than a 6 speed with all sundries

steve

sorry to hijack the thread but how much would it cost to replace the synchros in a 6 speed non dccd box

ive been going round the track and when im trying to engage any gear i hear a sort of clicking sound

cheers
