What Turbo Should I Get?

[buickrob]

So, with my current setup, see my sig below, what turbo would you get to try and run easy 11.8's?

Not sure I want to spend the amount needed for Ball Bearings though.

might be a bit much

My suggestion would be a 6152 dual bb unit. I ran the below time with alot less in the combo than you have (stock convertor, stock location ic ect.). With good gas or alky it should get you where you want to be with ease.

That's the one I was thinking of, a 6152. I haven't run the car since putting on the downpipe, alky, TT chip or front mount. I might even be in that low 12 - high 11 range right now if I push a lot of boost. Just thinking I might want a turbo that doesn't have to work as hard as the 44 to do 11s.

With my non bb te-61 and a front mount at 18 psi I went 11.48's at 118 mph. Other mods in sig, with a bb unit should be no problems at all and will spool real quick. Been thinking of upgrading myself but my turbo only has about 2,000 miles on it. Oh yeah launched with zero boost as well for that e.t.

You'll be shooting for low 11's for sure.

How are the 009's working for you? I'd order up some 60#'s while I was at it.

I would probably go ahead and run it with the new mods before adding the turbo. Might make diagonosing any unforseen problems easier. I prefer the BB unit because of spool, I think you would be very happy with that turbo.

BTW those 60#'s are probably a very good idea!

Well I got a 6152e and man it takes a lot for me to spool it. I knew it would take more than my old TE44 but didn't expect this much. Think I did something wrong or does it make sense that it might take a lot of throttle to get some boost with my combo? It doesn't seem to be spiking so I don't think I have an exhaust leak.

What A/R did you go with? If you went with the .85 it will spool slower. Also did you get a BB turbo? If not it will spool slower. Is your DP matched to your ex housing? Check for ex leaks and vac leaks. Make sure that your wastegate is working properly and you have the correct spring installed. If you have a scan tool/logger, check your readings down on the low end for a/f and timing. A 3000 rpm stall should be plenty for that turbo. Good luck. HTH

With not knowing much about the turbo and weather its bb or journal it could be a converter problem

[GNsnake]

You have more than enough turbo to go high 11's. I would try another converter. A 2800-3000 12 inch converter is borderline at best for a journal bearing 6152. Get yourself a good 3200-3400 9.5"-10" converter and you will see a difference in spool up for sure. A .63 exhaust housing would help greatly also, if you don't already have one.

you need 3200 stall converter with this turbo ,I ran that turbo with 3200 stall converter and it spooled realy nice , it happens that I am looking for 9.5" none lock up PTC for my combo so I have my current 3200 stall 10" PTC lock up converter for sale if you interested , it's a perfect converter for 11 sec car ,let me know

Thanks for the replies, I was away this past week.

The turbo is journal bearing and has a .63 Precision housing. No exhaust leaks but I'll have to check through for vac leaks. I replaced 90% of the vac hoses 4 years ago.

Bryan, what spring were you referring to? The wastegate is internal and seemed fine when I had the downpipe off installing the turbo.

Two things I'm thinking:

1. I had this 2800-3000 stall converter with a TE44 for years and it spooled up crazy fast. Maybe I was just really used to that. This turbo takes what seems like 1.5-2 seconds from a mash of the gas to reach 24psi or so. Once it has 5 psi it jumps right to 24 so it's just a matter of getting it to build. Maybe I'm over-reacting.

2. I've gotta get the cat out of the car. I know it is a 3" high flow but I'm sure it's not helping.

What do you think about the cat?

My 6157 doesnt spool very well with a 2800-3000 stall either.As everybody else has stated i think something in the 3200-3400 range might work better.

[bad V6]

The smaller/lighter 3200 stall converter is what this turbo needs. I'm running a 9.5" Vigilante and it spools as soon as I touch the throttle. The problem now is getting traction, even though I'm running drag radials on the street. However it is a blast to drive and play on the street.

I got stupid for a bit and didn't realize what you were talking about when you said spring Bryan. I have an HD wastegate on this turbo.

Do I need an HD solenoid to go with that? I remember Poston used to sell those.

I was speaking of the external wastegate. I must have been speed-reading your sig. Evidently I was being stupid. I now see that you have an internal wastegate. Sorry for the confusion.

Put 50# injectors on it and got a chip burned for the 6152e instead of using my TE44 chip with the fuel bumped up. Spools much better! Maybe I was way rich at the bottom end.
