No Boost

[hanyou]

hey guys.. i let a friend of mine drive my car for liek 2minutes and it came back f*kt.. its a r32 gtr.

he said he when he planted it and changed to 2nd gear it jus stopped boosting and he didnt feel anything sudden or notice anything out of the ordinary. it just stopped boosting

when i drive now it makes a noise as if air was coming out of the pipes.. i always had this problem with my pipes blowing off so i bought a hard pipe kit today.. but unfortunantly still hasnt fixed my problem.. ive also changed the spark plugs as they were caked with black stuff (carbon i think).

i dont know what else to do?. ive made sure all pipes are connected as tight and firm as possible.. all new o-rings/silicon hoses etc.

it smokes alot when driving too.. my mate told me there was blue smoke coming out of the exhaust.

have my turbo/s let go? or is it something else?

im gna try cleaning my air flow meters again but i just gave them a big clean a month ago.

mods are only catback, k&n hi flow panel filter, mines ecu

thanks

why did you let your mate drive your car?

and why did you let him thrash it?

[dead32]

because thats what good friends are for . i learnt my lesson not to let a mate trash my car when i seen a post awhile back about that dudes gtr gettin writtin off by a less then standard driver.... lesson learnt i hope..

[Godzilla32]

The black plugs are prolly cuz its running rich now due to lack of intake air because either one of your turbos let go or like b4 a pipe has come loose

[hanyou]

ah ok so if my pipes are 100% on.. then its my turbos?..

when i turn on the car it idles fine.. doesnt hunt or anything.. but if you rev it.. the revs drop to about 500rpm then goes back to normal.

any other idea's?

[gun32gtr]

id be checking turbos. if its not them adleast you have elimnated them... sounds turboish but

ah cool. thanks for that.. im pretty sure it may be as i blow my turbo on my 33gtst and had the same symptoms!. just wanted to make sure.

might as well upgrade then i guess

[hanyou]

oh and i should get the car towed to a workshop right?

or is it ok to drive it there without using boost at all (about 30min or so)

[Faid]

dude have it towed, as the ceramic dust can kill ur engine, and i dont think that you have calculated a engine build into your upgrade costs. this definitly is a blow turb, as i had the smae thing when a mate drove my car back when i bought it, nowadays nobody but me even sits in the drivers seat, be over protective, a GTR will make you bankrupt before you know it.

[gun32gtr]

yep tow it dude, you never no some of that dust may already be in there.. so yeh tow it

Yes it sounds like it could possibly be a blown turbo, but you can hardly say it deffinately is without seeing the car and making a visual inspection! Assumptions are the mother of all f*** ups. Are they even standard turbos with caramic wheels?

[hanyou]

yeah standard turbos ceramic wheel so all signs pointing to that

[SLIPPERY]

however, blue smoke as suggested by your mate points to busted piston rings as its the colour given off when oil is burnt

[hanyou]

is there anyway to check/confirm that other then pulling it out?. cause i asked a mate to drive it while i was inspecting the problem i didnt see any blue smoke that they talked about.. only white..

but when i turn off the car the white smoke keeps coming out of the exhaust for abit.

im probaly gna leave the car in the garage for a while till i get some funds to fix it all in one go. would it be ok to leave it off for about 1-2months max?

hmm hopefully its not a rebuild

hey guys.. i let a friend of mine drive my car for liek 2minutes .....

uh oh, spaghetti oh's . Does it have a boost controller?

The only other person to drive my car, in a year and a half of ownage, is my dad when I was on Holiday for 2 weeks. I think people only appreciate these cars if they have put the hard earned money and time into them, if not then they'll fk'em up!

Make your mate pay for it, a decent mate would fess up and offer to pay.

sounds like a turbo since you said that cause the oil is vapourising in the hot exhaust after the car has been turned off and this gives off the white smoke

haha yeah he has already offered to pay. i knew that the ceramic wheels would bust some day. im not making him pay for it as i knew the day would come.. but im happy he has offered too straight up.

it doesnt have a boost controller. jus the restrictor removed.

[Godzilla32]

Most of the time you will get the reminance of the turbine wheel in the front of the cat. So remove that and see what you find.

[wrxhoon]

If you busted a turbo you will find part of the shaft in the cat ( if you have one) . Do a compression test to see if you damaged the bore as well.
