Turbonetics BB 70mm

[Bescurred]

If I got this turbo, it says its a 3 bolt exhaust housing. My question is, If I have a ATR 3 inch down pipe would I have to have something fabbed up to make it fit? I'm overseas right now but If I remember correctly the ATR downpipe has 3 bolts TIA

What up dude...Ain't seen you on, didn't know you went overseas.

3 bolt housing refers to the bolts that go to the header flange, the DP side of the turbo is the same...and it's 4 bolts FYI.

What are looking into a 70 for?? You planning on buying injectors, stall, and a new intercooler also?? Someone had problems the other day trying to get their stock location aftermarket intercooler to work with a 70 because the housings so big the intercooler has to basically lean back to work.

hmm, I'm up to no good! SO the PTE stock location was having trouble hrmmm. I might just have to get a RJC intercooler, who knows. But come september imma be a daddy! THanks for the input colin. Hows Indy? or ohio..i forget which.

 

[Slow91z]

Wow you are really stepping up...New FM a 70, and a kid, most people slow down when the kid thing happens.

Don't throw out your intercooler just yet, you might be able to make it work, I'm just saying I remember someone saying they had some problems, but I think they ended up getting it to work...Tell you what though, if I was gonna spring for a 70, I think I'd spring for a FM.

Indiana's great, unemployment's great, having a good ol' time.

Yea, We'll see. I've got some money to spend. I need a trans, think i'm getting one from Brian. 60lb injectors and maybe a double pumper. This tax free money is racking up so I want to spend some on myself since come this fall I won't get to spend a whole lot on myself.

 

[Slow91z]

Sweet...are 60's big enough for a 70?? I don't know just curious.

 

[Bescurred]

Yea I just going to shoot for low 11s to High 10s they will support that, I just don't know about the fuel pump...how far will a walboro 340 hotwired go?

 

[Slow91z]

340 will go low 11's.

That is much more turbo then you need, if I were you I'd look at a 60 series turbo, like a 61 P-trim, a turbonetics 66-BB, something along those lines.

Are you gonna port your heads??

EDIT - Even a GT67, or a 45A would be much better suited for what you want then a 70.

a 70 will need way more injector than 60 pph.( I started with 72's and moved up to 83's with my 70) A lot mroe stall too. A te-45a may be a better match. I went 10.42 with one in 95 degree heat so it will still meet your et goals easy enough.

What stall speed seems to work best with a 70 bb?

3200-3300

He's just getting the itch with all of us GA Buick guys stepping our combos up for this upcoming season..... :biggrin:

A 70 is a lotta turbo for a street car Larry......why not just go with the GT6152 with either the E or S cover? I'm going to feed mine with 60/65# Motrons and they should be plenty, even with the roller cam, ported heads, and such. You also don't need a lot of stall with the 61....my 3200 Pat's should be more than enough for mine. That's another option for you to look at.....

126 mph at around 80% d/c 3600+lb car.

Hey man! I've also been looking at the GT 6776...i think lol So many turbos I just want a strip high 10 sec car and a low 11 sec in street trim (alky) IS THIS TO MUCH TO ASK LOL!

 

[Slow91z]

A 67 would do it for sure.

I'd still stick with a something alittle smaller if it was me unless you ported the heads...My personal opinion is there's no point in going with any turbo bigger then a 61 with stock heads, ported heads is a whole new story.

67 with ported stockers and a good cam (assuming you have all the other supporting mods) will go easy mid-10's.
