pre turbo dilemmas

[kraiye]

ok... i thought i'd just start one thread to put all my probelms / questions in rather than making 100 threads all over the place. :)

i'm buying a turbo kit that comes with a uni chip. i got no idea how to instal the uni chip and sure as hell no idea how to tune it!
i'm pretty confident i can do the turbo install but thinking ahead, how will i then get the car to a tuner?
i was thinking maybe if theres some way of setting 0 boost i could just drive it there and he could install and tune it then.
i'm also not sure if the stock ecu in my 98cxi will deal very well with the larger injectors i'll be putting in - i hav absolutely no idea how big they are.
may be i could drive to the tuner with stock injectors and swap em over when i get there.

ca$h is a big factor and i need to keep extra expenses to a minimum!

any suggestions/ideas very much appreciated.

just tow it
either get a tow truck or one of ur mates to tow it on a trailer

[JasonGilholme]

can't you just leave the waste gate open fully??? And use the standard ecu because there will be 0 boost???

[Q_ball]

You can tow it, or u can drive it untuned to the tuner.
Driving the car untuned is possible and wont damage ur internals so long as u dont thrash it or be boostin everywhere.
It really depends on how far they are from ur place of install.
Plz bare in mind tho, if you do get pulled over whilst driving to the tuners, u can get defected..HARD.
Turbo charging ur car and leavin it untuned farks up your emissions completely...take it from me :D hehe
Best of luck with ur install buddy, keep us posted!

if you remove the spring from the wastegate(for an external) or disconnect the wastegate arm(internal) you can get away with driving the car to the tuner. This is assuming it's not far, and you baby the hell out of it on the way there.

Also, the stock ecu will not control bigger injectors... wait until you have the ecu in to change those out.

thanks for the input guys...

believe it or not i dont hav a single mate in brissy with a tow bar. lol
and i'm on a hella tite budget so need to get away with it without towing -if possible

this is more like what i was thinking but had no idea how to go about it.

dumb-ass talk... just what i need! no... seriously!! i'm a total turbo n00b and sometimes require... the 'longer' explanation ;)
its usually bout 25 min drive but that includes 15 min down the highway.
maybe 35-40min the long way.
i picked up the rest of the gear today which included a manual boost controller that i didnt know about. sweet :)
after talkin to the guys i could prolly just screw the adjustment pin all the way in so it never opens the waste gate. otherwise i might have to disconnect the arm (its internal).

so what happens if i leave the vacuum line off the wg alltogether??

will do :thumbsup:
might be a while before i get a chance to hook everything up but will keep updated on which direction things go for those interested :)

thanks again

this is the opposite of what you want, as the turbo will keep building boost then!

Disconnect the wastegate arm so that the gate is open, and baby it

you'll be buying yourself a new engine... and probably get a nice upclose and personal view with one of the pistons

[NEED VTEC]

dont be a tight ass and tow it

[kraiye]

maybe i misunderstood and screwing all he way in would leave the gate open??!!
i thought all exhaust was directed through the turbo and the wg lets excess exhaust escape to reduce boost.
the impression i got today was the opposite which confused me, maybe i just misinterpreted what was said.
ok... this next question shouldbe in the n00b area but just to clarify how does a wg work?
is it open or closed by default?
when it starts to open/close, does it let exhaust into the turbo to start spooling or does it let exhaust escape from the turbo to reduce spooling?

PS: i'm not f*ing towing it ;)

screw it, i'll just hook the boost guage up under the bonnet and play with s*t till it comes out right. although will definatley start by disconnecting the control arm.
if i cop a piece of conrod in the head then its a learning experience. ;)

if u dont have an update from me in a month then i'm either still saving for the tune up or still in hospital :p

[saxman]

a wastegate is closed by default. As boost increases, it starts to open, allowing exhaust gasses to bypass the turbo.

With a boost controller, all you can do is increase boost from the setting of the wastegate. It is not possible to lower boost with a boost controller.

[kraiye]

awesome
thanks mate. think i'm gettin the hang of it.
so by removing the arm, theres no pressure on the gate from the spring so its effectively just flopping there and exhaust can push passed it.
and if i drive too hard there'd potentially be enough exhaust pressure to make some boost even with the gate fully open ie: why i must "baby the hell out of it".

i totally dont understand how the vacuums etc work in an engine but thats research/reading for another day :)

[saxman]

yes, that's the basic idea


I also say baby the hell out of it because you're changing the air flow to the engine around a lot, and even without making boost, your fuel and timing needs will be a bit different

Thats why NRMA roadside is great... free towing for first 15km!

[shecomb]

If you aint got the money to tow ya car to get it tuned, you aint got the money for a turbo Honda!.. sell the kit now

[string]

Do they need a reason to tow; i.e. broken car? Or you just ring em up and say, tow me bitch?

I didn't renew my roadside assistance since if my car ever breaks within 15km there's always a friend to bail me out and fix in the morning...

I vote undo wastegate arm and baby it. Anyone who tells you to tow it has more dollars than sense. You'll be fine, just don't go testing how much your new setup will boost creep by tempting it with some full throttle.

[ECU-MAN]

string is on the money

they need a reason to tow your car, ( thats how it works in sa ). I have tried it and they pretty much said "FO"

take the waistgate arm off and drive it nicely. if you gave it some the engine will see positive manifold pressure and go into Limp mode. in a way its a good thing coz it limmits the engine RPM and richens the fuel mixture.

but dont go seeing what it can do, like mentioned above, baby it. you will be fine.

[kraiye]

nice. just what i need to hear. :D
i was kinda thinking that because i'm getting an ecu installed (sort of) i could ring nrma and tell them my ecu is fried and need it toed to get replaced.
as long as they dont try and send a road side assist guy out 1st i should be sweet :)
unfortunately its about 20-25 k's though :(

it will be driven there!
