turbo problems!

[Kman]

right fitted my turbo the other day its up and running but overheating very quickly could this be down to the cooling system not being bled properly? also when i put my foot down it almost feels as if it gets to a certain point and shudders?? not sure if thats the best way to explain it?? just feels a bit restricted???? any ideas?? also when i took the old air box off it has a vacume pipe and a sensor with no were to go on my new intake pipe???

[sexoturbs]

overheating when driving? when driving hard? stationary?

what have you done for fueling?

[Kman]

yeah overheating when driving, goes all the way up to the red..

[sexoturbs]

have you checked your water? oil? is the fan kicking in?
is it when ur bootin it or casual driving?
what psi/bar r u running?

[Kman]

yeah fan is kicking in the turbo is preset at 5/6psi checked the oil theres enough in there and the oil lights gone out now its got water and coolant in but have tried bleeding it but not 100% ive done it right.

[sexoturbs]

oooh bleeding is a problem with most peapole lol. did u bleed it in all 3 places?
dad i check water agen after last time you went for a spin? or after it last ovar heated?

do you have a intercooler? is the fueling side of things still standard?

[Kman]

drove it tonight.. i have tried bleeding it in all 3 holes but nothing happens i start with the bleed valve and nothing comes out??? the fuelling side is standard at the moment and ive got an intercooler but not yet plummbed in as i cant see were to put the pipes??? ive cut the holes out of the slam pannel but it all seems a bit tight were did you run your pipes have you got a pic of all angels??

[KrisB]

I assume its been mapped?

[scot-ish]

you need to take a step back, before you fuck it all up

no intercooler?? same fueling as standard. are you tryin to blow it up

do you know how a turbo works mate, compression of a gas, will put severe heat into it, combined with no intercooler, and no fueling sorted, your lucky the car still drives. the whole thing will melt soon enough tho. running lean isnt a good idea

decomp plate??

[sexoturbs]

well theis you problem lol. i think i dont the bleed behind the engin 1st. so fill it up inscrew the niple and have the car running. keep makin sure its ful of water and replace the nipple when u see water come out. if no water comes out then something is wrong.

maybe your thermostat

[sexoturbs]

this is the link to where i ran my intercooler pipes...

http://www.saxperience.com/forum/showthread.php?p=3602364

[Kman]

so i need to bleed it properly and then what fit my intercooler? what size pipes / hoses did you use? and once thats done fuelling??? 5th injector kit???

[sexoturbs]

so you dont have any plans at all aon what you are going to do and just bolted it on lol. read that link questions and answers should all be their. pipes 2.5" i think somethin like that. i just used 6 90 degree silicone hoses.
fueling... sigcon, mf2 and fith injector or biger injectors standalone or remap.

[Kman]

yeah was planning to plum my intercooler in as soon as and get a 5th injector kit and thought that would be pretty much it??

[sexoturbs]

you wil need to lower the compression.... forge or decompression plate.
sort fueling. mf2 or standalone
intercooler.
better brakes.
better spark plugs would be good
turbo timer would be good
air/fuel ratio guage if you go mf2

[Michael86]

you have fitted a turbo without an intercooler? lol cabooooom

[sexoturbs]

you have fitted a turbo without an intercooler? lol cabooooom

lol the car wont blow up just because it has no intercooler.

[col101]

No. It's everything else that hasn't been done that will make it blow up

[sexoturbs]

lol...

[Kman]

whats gunna blow up then??

[sexoturbs]

they say yours will as it has no management or remap. or anything to sort your fueling.

did u manage to bleed the car properly?

[Kman]

i think so, i had water coming out of the valve cap and the allen key bit so hopefully thats done... cituning sell the kit i have as a bolt on kit im not saying i leaving it how it is but why would they sell a kit to blow up your car????

[sexoturbs]

yea if water cam out of the back niple and on the thermostat allen key bit should be ok now. just kep an eye on the water over the next week make sure its still their. shouldnt overheat anymore.

cituning sell the kit to make some money. bit i think if you got them to supply and fit they would prob give you a remap or recomend one at least.

[Kman]

didnt think you could remap standard ecu? dastek uni chip any good and would it benefit me??

[sexoturbs]

yea you can get it maped. think its like just telling ur car to take more air and fuel. in a way.

i was going to go uni chip but the guys that do it near me just change their minds with price every time i speak to them so im goin emerald. but yea get some better injectors then get the uni chip will feel alot better and drive alot safer

[Kman]

any suggestions on injectors?? my care has the blacktop engine do you no any that will fit???

[sexoturbs]

im not sure if the black top and silver top are the same. they should be tho. im geting bosch green injectors from pug1off. they are about 450cc.

i have tried looking for them on ebay but dont no wat gerrn i need. their is light or dark. if you lok around you can find some. u could get 701s. bmw beige injectors. theirs loads.

people say use pico but im sure they are only for vts some say they fit vtr i dont think they will. pug1off said they wont ither.

[Kman]

whats controlling your fuelling and management at the moment?

[sexoturbs]

nothing. not long sold my mf2 and fith injector. im just driving about inder 3k revs. lol im tryin to get enough for my stand alone on 37th of nov. but not sure if ill have enuf :(

[Kman]

perfect date.. think thats when ill get mine done, how does yours drive?? and how did you rate the mf2 setup??

[sexoturbs]

i dont drive over 3000rpm so normal lol. before i had my decomp plate done it would struggle at bout 4000rpm then giva power agen after 4500rpm. i cant realy rate the mf2 setup properly as i never had the sigcon so still wasnt running as smoothly as it should have.

who will be doing yours?

[QUOTE=Kman;3809357]whats gunna blow up then??[/QUOE]

Right first off Get the cooling sorted, bleed the system right if your turbo is water cooled might be an idea to fit a larger rad, cheep option for this is a diesel rad.

The feeling of the car being restricted is it running lean ( too much air and way to little fuel) this will be a very big prob for you because it will melt a nice big hole in one or more of your pistons:wall: Your options for sorting this out are giving Gmc a call and order a Mf2 a sidcon and a fifth / sixth injector (depending on expected power) and a injector elbow, oh you will also need a different map sensor. Second option and its the best would be to buy a stand alone ecu like a predator or kms and injectors to suit the fulling for expected power.

You can not use standard ecu and just get it mapped the oe map sensor can not see boost so thus leaving the standard ecu useless.

A intercooler is not necessary at low psi but will help prolong the life of the engine and drop the intake temps down helping to improve power.

diesel rad has never been passed to ma as a option. i just have the vtr rad but was goin to buy the vts rad. is the diesel one alot bigger than the vts? and is it just a straight fit int the vtr?

I have a standard vts rad mate. Got it with vts engine just bought.

Yeh they are little bigger and also have a separate header tank so gives bit more room at front of engine.

[sexoturbs]

nice one :) i think i will purchase one of them.. any special sort? like nissens?

[jinjan]

Looked into charge coolers? Also get a W/I kit fitted, helps ten fold!

[GeorgeSpasov]

I have Saxo Vtr Turbo with standart ecu remaped with standart map sensor bigger injectors and the car is still runnig good for 2 years on 1 bar Ihi Vf34(Impreza STI)
my question is why map sensor doesn't make any problems?

[sexoturbs]

yea the standard 1 should be ok on low boost with a remap. but if you are geting forged pistons and rod im sure u will try running over a bar and i think u will get a few problems then specially with the standard map sensor

[sexoturbs]

what the hell is all that? charge coolers like http://www.thor-racing.co.uk/Barrel_Charge_Cooler_120-PWI_3204.asp? dont no wat the rest means lol

I dont understand how it dose mate since i know the standard map sensor can not read boost only a vacuum there for should not work.

[GeorgeSpasov]

maybe this is the first post i read about that i really have no problems on this boost with standart ecu.i thought that something with my car is not correct.i'm sure that on higher boost my map sensor will do some troubles

[sexoturbs]

yea my m8 crashed his saxo 1.4 turbo but he could do 1/4mile in 15.2 he still had the standard ecu. i never looked into turbos and saxos as much as i have now but i no the ecu was standard. cituning done it with a remap i believe. then they told me i could just bolt the turbo onto mine and it would be fine which its not so im now stuck spendin more and more money lol. i have to beat this 15.2!

[Kman]

right my saxo is still getting hot to quickly.. i also think my dump valve is not going off properly... also i think that i can hear the turbo spinning possibly metal to metal???? not sure tho..

[blackie_2k5]

turbo doesent sound to healthy, if its fucked and it metal to metal it will be very hot, could be there bearings being starved of oil could be fook impeller, if it is fooked the extra heat its putting into the oil or water could be making your car over het, first post ive read since first page so not sure whats been said or covered or what turbo your using etc......

mate, a 16v would have saved you a lot of cash, and got you that time without a tubby lol

[sexoturbs]

mate, a 16v would have saved you a lot of cash, and got you that time without a tubby lol

yes which makes it to easy and less fun :n: everyone wants a 16v and every time i drive my saxo they say no way thats a 16v but soon they will say what the hell is that ha and ill say just 1.6 8v :homme:

just feels like i have achived more... lol

[Kman]

got my intercooler plummed in today and had the cooling system bled by a machanic its all running really smooth now and temps stay down... found out the metal noise was my radiator fan were it had been relocated... well pleased....
