R34 25gt Manual Transmission Same As Gtts?

[saga]

Hi, as the title states: does anyone know if the 25GT manual gearbox is the same one they use in GTTs?

the reason i ask that is because im planning to turbo my rb25de neo but need to find out if i have to upgrade the gearbox or just the clutch?

cheers

rebuild the RB25DE into an RB30DET....great engine with a ton of power.

Change the transmission...it will die with that sort of power going through it, upgrade toa GT-T box.

thanks Dan

so you are saying that the 25gt manual gearbox is different to the gtts one?

have you changed the standard gearbox in your 25gt for the kind of power you are making(150rwkw correct?)?

cheers

Yeah the gearboxes are different, very similar but different. I left the auto in my R34...it only had a couple of clutch plates less than the GTT box, and also had a lower stall point so wasn't as excessively abusive on the mechanicals...a manual box would cop it a lot more, so should be swapped.

I don't have that car anymore, it was stolen and written off...so I'm now going through the upgrade process with my new GTT.

Once you've driven a high-compression car with a turbo, it's funny going to the factory lagmonster!

haha thats right! i like the idea of high compression engine with a turbo less lag!

if i leave the factory 10.1 compression and run a turbo with no more than 7psi boost, instead of using a factory gtt turbo, in theory wouldnt i make more power with a bigger bolt on turbo like an gt2835?

im also think an aftermarket high mount manifold, an aftermarket front mount intercooler and a gtt upgrade full exhaust. many of these parts are selling at a bargain price on ebay. hows this package sound to you?

oh and ofcourse PFC!

The only other example of a high-comp R34 turbo conversion was in Greece, it used a TO4E, which spooled up very well with the compression. Best to wait and see what turbo you decide to buy...as you're going to have to get custom piping and flanges for the exhaust and intercooler, nothing on e-bay will really suit.

Don't forget to try and get hold of some GTT injectors, a fuel pump, and an uprated fuel regulator to make tuning more simple.

Here is the other 25GT

Here is my car (at the assessors after it was recovered) as you can see it used lots of revamped parts from other skylines.

thanks for that,

so heres the plan:

aftermarket high mount manifold designed for rb25det with t3 flange and external wastegate type(i suppose it should be a direct bolt on to rb25de neo right?)

hks gt2835 turbo (as i can buy one off my mate dirty cheap)

external wastegate- just love the sound

and all other gtt parts as you mentioned above.

now just two questions: which type of PFC to get? and what about the stock airbox? would it be sufficient? or need custom intakes too?

cheers

OK...both of these cars used the e-manage, but I'm 99.9% sure you'll be fine using the normal GTT PFC, as all the connections and ECU sockets are the same. The only thing I think you'll neeed to invest in is the optional pressure sensor for the PFC. The GTT has one connected from factory, this will most likely be the input that would confuse it, if it wasn't there.

Stock airbow should be fine, put a pod in if you feel the need.

Can you get me one of these dirt cheap turbo's?

well not exactly dirty cheap, its a garret turbo dont know the specs yet but similar to a GT35, for under 2k. cheap in comparison to an internal wastegated hks gt3037 which retails like 5k if im not wrong.

so yeah sure mate, if u want one i guess i could get u one. no worries

you would probably need custom pod intake to make room for the highmount
