getting turbo running

[trdfxgt]

my 4 agte is all in the car and ready to go but iv hit a problem some $&#$% gay mother $&#$% robbed my house and stole among other things my link computer it is insured but its going to take a few weeks to get it back i want to get this car running in the mean time can anyone who has had a turbo car running on a with a blue top computer tell me how they got it going and boosting im sorry i know i could search this but they also took my computer so i can only post from work and im not able to spend much time on here any help is much appreciated cheers

[crnkin]

just hook it up and drive it, stick with under 5psi, and yeah, do et

[slighty_sykotic]

If you have just rebuilt it all, then I wouldn't do it....

If you get it wrong, or get a bit boost happy, then it will $&#$% your new motor, and your way back to square one.

If its just a shitty motor, then yeah, wire it up, set intial timing way back and go very very very low boost...

Be careful.... I personally wouldnt risk it, unless someone here has had the a/f ratio checked on 5psi and can confirm its safe with stock E.C.U.

A stock E.c.u aint mapped for positive manifold pressure so how can it fuel it correctly???it will only supply fuel for 0 vacuum wouldnt it.

just my opinion

[sergei]

if it has AFM it will fuel according the load (ie amount of air sucked in) so for ECU it does not matter what sort of manifold pressure. The issue would be with retarding ingnition at boost, as the N/A ecu will not do it.

My bad, good point!, I just presumed its using a map sensor

[trdfxgt]

it is a map sensor type i had heard of lots of people doing this ??? im confused now if it wont work then thats all good i only wanted it drivable not to rev hard out or anything but im sure iv read of people running up to 10 psi on standed blue top engines and computers ?????

[crnkin]

Dont listen to the above people, only sergei knows what hes on about.

Its fine, i run it, many others run it, af's are around 13 at 10psi on a t25, so to be safe, 5 pound, runs about 12.0 across the range, starts at bout 11.

Pm me if you have any trouble, but its as easy as seting up and going.

However if its a fresh rebuild, you want to get about 1000km's driving in to run it in.

Hahaha are you sure about that statement buddy? You dont know Syk or myself from a bar of soap, so how can you judge what we do and dont know?? You seem to go on alot about 4agte's and turbos yadda yadda, but do you actually own one?? show us a pic of this mysterious 4agte monster your building and then ill know you walk the walk and arent full of sh*t

hahahaha chris 4agte master!!!

haha dick.

Ive NEVER EVER said ANYTHING about a mega 4agte, however yes, i do run a 4agte, and have for a little wee while now, so like i said

SHADDUP

[Mr Revhead]

personally id wait till i got the link

coz i know full well that the 2nd i feel boost id floor it and go "yyyyyyyyeeeeeeeeeeeeeeeeeeeeehhhhhhhh" *BANG* "aw crap"

[trdfxgt]

ha ha good point can i ask this though say you did do this set up on a corolla and you dyno it and it was not leaning out why else would it go bang ??? i know its not the safe thing to do but has anyone actually run this kind of set up and dyno tuned it just to see if it is gettig dangerously lean just curious

[slighty_sykotic]

leaning isnt the only thing that will kill motors. Timing is by farthe biggest worry with std NA computers and boost.

Boost plus advance = bang.

--Sykotic

[trdfxgt]

see this is why we ask these questions i did not know that so the timing out is the big killer i had always assumed it was the leaning out that killed them burning the pistons that sort of thing

[Mr Revhead]

leaning will cause melt
timming will cause detonation


try it set the timming to 5deg.

i think the trick is to leave it in diagnostic mode so it wont advance it

I wish people would search.

Above is one of carls dyno graphs at 10psi, stock everything, no intercooler, 117kw atw

How long did that run for karl? bout 4-6 months i think if i remember correctly.

Just one of the many documented times the 4agte has worked flawlessly.

Basically you need a low km engine. The trouble with mine is it had done 300,000 km's, and i was running 13psi on it (up to 25psi at times setting boost controller)

Still lasted a few months.

However, if you have a link to go in, run it, but its safe as on 5-10psi

[slighty_sykotic]

What you just said basically is the final point. If you have a old motor, or a motor you don't care about, then go for it.

If its a fresh rebuilt motor, wait for the link.

Because if what you said is right, and that a good motor lasted 4-6 months... Thats not reliable in my books. If you said 4-6 years that would be better. And if you have a fresh motor, and a link, its deffintly going to last 4-6 years if tuned right.
