Driving The Car With Untuned, Larger Turbo(For Now)

[SargeRX8]

Ive got some free time tomorrow and on the weekend to fit my turbo onto my car. Thing is I won't be able to get it tuned until Tuesday. If I fit the turbo in and just drive the car like normal, no boosting or f**king around(I rarely do anyway), will it be fine? Ive driven 600km when bedding in my clutch without ever hitting more than 1psi so I'm sure I can do it. Will it affect the "cruise" style driving? I probably won't drive the car only when I gotta pick mum up from the shops etc.

I just don't want to wait until sunday/monday to start only to have something not go to plan and then have to wait even longer with the car off the road and miss my tune.

Cheers guys.

Yes it'll be fine.

Dont hit boost, low rpm/throttle blah blah.

Yeh I installed my turbo and drove around with it untuned a few days before I could get my car in to be tuned. No dramas, just don't boost as has been said

[rondofj]

so what happens when u boost it? (untuned) - does it act all weird / jerky and stuf because the afrs are now off??

Could lean out, destroying a motor.

Usually ECU will shut the show down, but if it doesn't you are in major strife.

Woop. Tomorrow I begin installation then off to the advan.

even hitting boost wouldnt be bad as long as it was only on stock 7psi

you can crank boost up on a standard turbo/ecu and its ok so a bigger turbo on low boost wont be too bad either its the same principal your giving the engine more air, give it too much air and it will not have enough fuel, thats why its not recomended

what you dont want to do is put too much sudden load on it, that is dont drop the clutch on boost, or mash the pedal.. If your boost is kept low and you let the engine load up torque it is ok.. I drove mine around for a quite few weeks like this

7psi under this turbo is not equal to 7psi in the standard turbo. Ill be driving like a bitch until its tuned lol, just wanted to make sure it should be fine.

[ARTZ]

think you read it wrong, what i was saying is 7psi on your new turbo could be close to equal to high boost (aka 12psi) from your standard turbo

[SargeRX8]

Ah true, I see what you mean now lol.

[ARTZ]

yeah, just take it easy

on a related note im swapping in some 740cc injectors and a z32 running off a power FC, now if i configure these with the Hand controller how will the car behave without a retune?

Just wanna take it down the street to make sure everything else is working okay before i hand it over to the tuner...

[JonnoHR31]

if you use the right injector corrections it should drive exactly the same

Wow and might I add that Ive done a clutch and a timing belt, but this turbo install without a doubt is the worst, most fiddliest shit I have ever f**king done.

The car pissed coolant everywhere, the f**king nuts to hold to the manifold are a pain in the ass to tighten, the middle bolt on the back of the turbo is a f**king pain to tighten, screwing in the banjo bolts omfg the list goes on.

Without a doubt the worst job I have ever done. Then it starts raining on me and I cant continue until tomorrow. Hopefully I can get those rear bolts tight enough and the tension I put on the turbo to manifold bolts is good enough(3 are very tight one is not as tight as they are).

Shall be interesting to see what headaches tomorrow carries.

its fun hey.. I would rather do a turbo than a clutch anyday

how have you done the coolant lines, did you cut the old one or take it off. cause getting the old line off the back of the block is near impossible..

Your lucky if you didnt have any broken manifold studs I had 5 broken, extra 120$ to get drilled and replaced and managed to shear a power steering line (dont ask ) another 70$.

Just dont do what I did and forget to put the bracket that holds the intake pipe up,if you took it off that is, cause you will have to take the manifold and everything attached to it, off again to do it.

last buy not least I forgot to attach the turbo oil drip line and had to cut a spanner in half to attach it on the car an 1/8th of a turn at a time
