Gtr Stalling And Not Hitting Boost

[gtr2env]

hello a mate of mine has a 91 r32 gtr and the other day he was driving and the car would not hit boost and

when he would take hes foot off the gas it would stall ,what could this be ,a fuel prob or what .

as i am trying to help him out with fixing it lol no money like me.also it was runing very rich but what he tolded me.

thanks

sounds much like an AFM.

check they are connected properly, and clean them with electrical contact cleaner

[gtr2env]

cool thanks mate ,cos i was thinking that it was a fuel prob and that it was having a vac leak some were ,thanks ill give him a buzz to do that.

[gtr2env]

hello guys any othe ideas on what it could be cos we are going to try fix

it this weekend if we can.

thanks

intake leak... like a cooler pipe/hose leak.... or AFMs...

[gtr2env]

cool the more info the better.

thanks

[gtr2env]

also whats the best way to clean the afms.

[gtr2env]

ok i tryed cleaning the afms with metho and it still wont hit boosted ,and is runnig very

rich still.

[Topaz]

if cleaning them didn't work it might be, electrical?

[gtr2env]

hello we have tryed every thing now and it still wont hit boost ,but

we have taken the pipes of the front of the turbos and there is a shit load of oil there does that mean that the turbos are gone maybe.

thanks

Exhaust wheel gone off back turbo maybe?

I had the same symptoms.

[gtr2env]

thanks mate lol ill have to look in the cat for it.

[gtr2env]

also would it be hard to replace the turbos and how much would it cost

to get em put in.

thanks

[gtr2env]

ok my mate just got a quote to get it done for $1000 with him geting the turbos ,is that good,as they guy was says they would have to take the motor out as it it to hard to do with the motor being in the car.

[wrxhoon]

No need to remove the engine to replace the turbos, take it to someone that has done it before. It should take a max of 8 hours to R+R low mounts on a GTR.

[Guest Variable]

I paid $700 for my turbo swap over with me supplying the turbos.

[jwah]

I changed my turbo's myself about 6 months ago. I would definitly say pay someone to do it. but im just a bit of a cheap c*nt!! So much frustration and ive never done anything like that before. But the quote i got was somthing like 1500-2000.... Make sure if your going to fork out money to get new turbo's put in, make sure they are worth while like N1s, 25-30s or t517z's or somthing. dont put back in crappy old ceramic wheeld turbo's. you'll be forking out more money in 6 to 12 months depending.

Cheers

Did you check your BOV's. Leaks are so common.

[gtr2env]

my mates car is all fix now but he needs to replace the spark plugs as

they are now f**k .

[gtr2env]

hello people we changed the spark plugs last nit with ngk's that cost like

a $130 and the can ran fine for about 5 mins that now it wont hit boost

again,what now could it be its realy pissing me off and him.any help would be heaps good.

thanks
