As i was discussing with craig, If you've got work to do on your car and dont really have time to transport your car to a mechanic, or want it done over a weekend, or dont know what the fuuk your doing, let me know the quote and ill beat it by a considerable amount and help you out.

Cubes, i agree with the gt3540 being a '3rd gear' turbo, especially the typhoon spec 1.06 rear and also the .82 rear. Very impressive once on boost tho. I have done a little reasearch on a gcg gt3040 aswell, they are much the same to some extent.

i got a gt 30/40 highmount with a .82 and external gate on my car n they are a awesome turbo, when boost hits it hits HARD!!!

1st 2nd n 3rd gear, they arnt that laggy....

then again thats on a forged engine, i guess it'll be a bit laggy on a standard engine, but if u wanted it more reponsive put a rb25 or .63 exhaust housing on it, thats wat i had on it when it was a stock engine b4 it was blown up on the dyno....

Probably a few other reasons why it's not as laggy but how does a forged engine make the car more responsive than a standard engine?

Lighter internals? Rods/pistons etc?

if that was the case, then 1/2 psi extra boost on a car with STD internals would take care of that.

Peeps generally do a rebuild with forged pistons and aftermarket rods to be able to cope with more HP, RPM & strength.........not for better response.

I am not a fan of the 3040 on the twin cam heads they are a bastardised turbo. :)

As you say boost hits hard that = lag.

I'd prefer a much more linear turbo that comes on earlier so it doesn't feel like it hits so hard due to lag.

    • I'd be worried about having to parallel park a boat like that. Magnificent car though.
    • This car has run before on this z32 ecu can get the part number for you, I have tried with no AFM it didn’t change anything, I compression tested today 140-150 across all 6 cylinders, also set fuel pressure to 43psi. The only weird thing was cylinder 1 plug was black and fouled other 5 cylinders were just wet with fuel. Spun cas by hand and confirmed injectors are clicking 
    • Since you came here to ask for help, have you thought about answering our questions, that might help us lead you to why it was skipping, or have you given up on getting advice?
    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
