3000gt vr-4 i just got some questions please help

[jason_bet]

so i just got a 92 3000gt vr-4 with a blow engine i am trying to figure out if i should/can replace the 92 engine and trany for a 6 speed 94 engine and trany?? how dificalt would it be to do? i will be doing the work myself on it.. and how are the stock clutchs in 3000gt's? when i have the hole engine out should i go a head ant throw a upgraded clutch on it? also wile the engine is out is there anything that i should do to it before i put it in? any info will help thanks!!

[Musashi3000GT]

the engine is the same so the six speed should fit right in. The stock clutch is good if your gonna leave it stock. the worst thing about the transmissions is the syncromesh, so you should replace them while your at it. sound like a fairly easy swap out job.

Edit: I just realized your gonna put in a new engine too along with the transmission. yes it will fit, I dont know how but your gonna have to change the shifter or at least the gate so that you can get it into reverse. the aftermarket clutch wont be necesary unless your gonna make loads more power.

[Stealthee]

There is no gate to change. Its all cables. If you get a 6 speed tranny you will also need a 6 speed rear end as its geared differntly.

so would you sugest me just keeping a 5 speed in my car then? also i hear there is a difrence between the early 92 and the later 92 is this true? if so wich is better and how do you know?(wich numbers is the date made on the vin)

[Stealthee]

The difference is in the output shaft. 18 spline vs 25 spline. You will not have issues with that unless you are making regodamndiculous amounts of power.

[jason_bet]

the output shaft? unformiliar with this? what would you sugest? should i go with the regular 5 speed? i know some about cars but im still new at it i have only been turning the wrench for about 4 months... is the 6 speed going to help me out a lot of even at all?

[jason_bet]

also what is the stock pounds of boost on a 92 3000gt? and if i turn if up what is a safe pound to turn it up to?

[Thourun]

Regular 5 speed is fine, I've owned a 5 speed SL and a 6 speed VR4 and I liked the 5 speeds gearing better lol. Go read the FAQ, it will answer your questions as well or better than we will (we're lazy somtimes).

[Stealthee]

LOL. Lazy isnt the word for it. There is tons of info to be found. If you dont already know about check out 3si.org. There is a ton of info to be gained from there.

about the boost mod, check the FAQ in the "free boost" part

[Stealth-Twinturbo]

The biggest problem with the stock boost solenoid is that it can't hold any boost to the redline. after 4000 rpm my boost went for 11 to 7, With the free boost mod. I bought a EBC and now i hold 12 psi right to the redline it makes huge difference.

[Igovert500]

That is not the fault of the stock boost solenoid...that is the fault of our small 9b turbos. Regardless, something wasn't right if you were only holding 7 to redline, as you should be able to hold 10 to redline stock.

[crazy_quick]

The newer 92's have a 25 spline output shaft, stronger then the 18 of course. And they also have a 4 bolt main as opposed to the 2 bolt main. The stock block is stronger and can hold more power.
