I took off the charge pipe to the intake manifold and rev'd the engine by hand and felt the air coming out of the charge pipe...and until like 6k RPM (I had someone watching the tach) it doesn't feel like enough boost is being spit out to actually boost my speed.. Is this the infamous "slow spool" or just a weak turbo? I also watched my wastegate arm that opens up the exhaust bleed and it did not move at all the whole time I rev'd the engine.

Um, unless you have a small turbo, you're not going to be making boost without engine load(revving in neutral).

 

Like he said, no load means no boost. Or i mean at least little boost.

My turbo wont build boost in nuetrul.

Hey im in OKlahoma TOO!!!

what is your setup?

and im out,
Josh

 

My setup is a 1993 Del Sol Si with a FUCKED *** oil leaking smoky turbo. I have to go get a rebuilding quote on it on Monday. My turbo is pretty small, and generates pressure in neutral, but I guess it takes load for it to boost hard.

Oh yeah, by the way, my turbo doesn't spin at all at idle. Isn't it supposed to? I read that it is. I guess its just my worn turbo acting up?

 

it should spin at idel.

slowly

 

mine did not till i rebuilt it. and now it spins at idle

 

Cost me a little over 3 bills to get my t3/t4 turbo resealed and shipped.

 

Well I have a place here locally called Thompson Turbo. They will charge 120 for labor and balancing the shaft, and like 100 for a kit that includes bearings and all the seals. Is that a good deal?

 

I can get your turbo rebuilt in Edmond for like 100 bucks i think. if you want you can e-mail me and ill throw you my number so you can call me up about the pricing.
