to rebuild or to not rebuild..a turbo that is...!!?!

[TRDmod]

car st205 1996

this is annoying, ok i have now decided to rebuild my turbo to a steel internal one, so i can run 17 psi on my stock internals engine......

i call alltech turbo and diesels, to cut a long story short, they said, yeah we can rebuild that.......no problems, to steel internals, but he said he does not recommend runnign it at more than stock...y?

i am told here in this forum that its ok to run it at 17 psi once you rebuild to steel cos the ceramic is whats unreliable.....but now hes telling me not to...can anyone shed light on this

no im considering getting a aftermarket turbo - trouble is i have to apparently get custom manifolds for that as there is no turbo out there that can just strap onto a gt4 easily, feed back please....!! i am frustrated

thanks dr rosie:)

After market bolt on turbos not specifically for an ST205 but should work.

The ceramic CT26/20b turbos have a rep for not liking high boost. But Al's CT20B MR2 seems to have worked up to 20psi for short periods. Maybe its something to do with the downpipe because the stock one is horrible... really restrictive.

What did the re-build consist of? you should price a new steel CT20b maybe

did you ask them for any reccomendations for a different turbo?- ive found them pretty helpful in the past there & they know their shiz pretty good imo

[Mr Revhead]

were they meaning the turbo.. or the engine?

were they meaning the turbo.. or the engine?

I think they were probably referring to the engine. As in keep it all running stock so they can't be held accountable for any 'mishaps' because they aparently said 'yea with this new steel shaft you can run 17psi not a problem' and then by some coincidence something craps out...

[Mr Revhead]

yup thats what i thought

[TRDmod]

no no no, definately the turo, i went through it 3 times to make sure, l;as you guys know i like to go through things multiple times

they said they dont suggest 17 psi, though everyone else says its ok....like you guys.....i guess he cant give warranty on 17 psi....
but....the engine he says isnt the problem anymore than 17 yes, it would be he said 17 is not that much its the ceramic that might give in, but he says that steel is definatley stronger but something bout the plate?? plate? is still the same or something

[Silent Knight]

Ok seriously...were you drunk when you just wrote that?

Then engine from my knowledge would handle 17psi on stock form no problem yes. If the turbo was to be properly rebuilt with steel internals then I don't think that would have much problem handling 17psi as a unit either.

They say it won't because they don't want to be liable or held accountable for any damages that would/could possibly occur if you wound it up to 17psi and something by accident/coincidence went wrong.

Who did you speak with at Altech anyway? Talk to Cully...if he still works there I am unsure but he knows all

[TRDmod]

no i wasnt drunk....thaks for hurting my feelings, my heart right now, has been cut, cut really deep, it hurts...silent knight.....u have hurt me, .... u insulting me has hurt my hear tso much, hope you are happy...i love you too

back to the topic,
thats what i thought, that they jsut dont wanna advice that but i mean 17 isnt extreme......i just wantedt o see peoples opinions, it kinda scared me when he said that, cos why would i spend close to 900 - 1000 rebuilding if its useless to me...!!

thanks guys
silent knight, no need to get nasty, i jsut did a 14 hour shift.....

thanks

I wasn't being mean at all. Was just wondering by the way you were typing the message

If I have in any way offended you, I sincerely do apologize

17 psi isnt excessive, but it wont last like youd hope. espically if the cars doin lotsa km's, after a while things like piston ring n valve guide seals start to feel the boost n may giv u excessive crancase pressure n blow seals out, or youl just use lotsa oil, but hey the car'll go hard!

id go 4 it,

[TRDmod]

thats alright silent knight i over reacted.....arent we mature:)??

ok, so you are saying to me that my engine will blow its self to shiz kingdom come ...

my usage would be normal psi daily driving, (thye car isnt a daily driver anymore - maximum 5k a year) iw ill have a g reddy type is with two settings for lo and hi....

and 17 psi on the track and when i want some grunt....

i mean the block itself and the engine is very strong, 17 shouldnt be a problem should it?

anyways else have experience int his, will 17 psi f$ck up my engine like he says?? i mena if that happens, i will then have to rebuld the engine......

would an oil cooler help prevent this to keep the engine cool??????

No, you're engine won't blow up and an oil cooler aint going to do anything. He meant in excessive use. If you run the car everyday constantly on 17psi then after a while the engine will start feeling and you may run into trouble.

Buy a brand new Steel Ct20b off MrRevhead and be done with it and while you're at it you should be able to sell your ceramic Ct20b for about $800 and yes you can run 1.2bar+ no worries.

[TRDmod]

mr revhead, how much would that me to get a brand new st20b steel....?
