So Whats The Baddest Street Turbo Out There???

[ReaL99]

I have heard that the GT-61BB is a great Street Turbo.I don't plan on going with a new converter higher then 3200.There are some guys that will say go straight to a 66 or 67BB but the GT-61 or 6152 Turbo should be enough Turbo for the street.Also it probably spools a bit quicker then the CPT-66 and 6765 Turbo's.Any thoughts on what is the funnest Street Turbo to have

You have the heads and intercooler that would run great with a 67bb turbo. Get a set of 60lb injectors along with the thdp and the 3200 stall and you should be around a 11.50 or better street car on pump gas(93 octane) without having use nitrous or alky. I would go back to a 3:42 gear if you ever have to go into the rearend for anything.

I don't know if my wastegate set up near the middle of the crosspipe hurts spool up.Also I have these 009 injectors that I want to replace with the 60lb injector's.I got great CNC Ported Race Heads and Intake along with the front mount intercooler but even with new Tech Turbo's the 67 Turbo probably doesn't hit as hard on the street as the 61 Turbo.I had a big Turbo on my car once over 10 years ago but it was laggy as hell.I wonder what the difference would be on the street between a 61 and 67?? On the street is primarily where the car will be driven.I also would like to get the THDP in the future but I don't know if that will help with the spooling of the Turbo.Car spools great off the footbrake with the TE-44 though, but I was told that the 44 was to small for my set up even though I still have the stock cam.I always like riding with the 28 inch tall tire's with my 3.73's so I don't know if I need to put the 3.42's back in unless I suddenly gain power somehow early in first gear.

I will know how well it spools at some point as I already have the turbo(67bb), just waiting to put the engine back together. I have a 3in thdp and it helped spool up alot along with the atr exhaust. I will be going from a te44 just like you as our combos are fairly close. I have the gn1s heads and i'm going to a roller 210/215 cam. I went to a 28inch slick from a 26 because at the end of the quarter it was running more rpms than I wanted. As far as gaining power in first gear you will be if you go with either bb turbo(61 or 67 with .63). With the 3200 stall you will have, I would go the 6776bb for sure.

The only thing about the 6776 is that it seems to require a bit more tuning then a smaller Turbo.The bigger the Turbo that usually is the case though.I also heard that the CPT-66 is a great street strip Turbo.I just don't know if I need a 66 or 67 Turbo if the 61 is easily capable of running in the mid to high 10's.I want a Turbo that is going to rock and be very responsive on the street because my car will probably rarely if ever will see the track.I just love the hard hitting power on the street.

i run a bb cpt66 with a 3200 stall no lag at all even at zero lbs of boost it was just gone , instant boost , its a nasty turbo

I'm curious, what kind of times are you running with your CURRENT setup in your sig?

I never raced my car with the 44 in it.Alot of guys including Jack Cotton likes this Turbo the best as far as street and strip is concerned.I was wondering what kind of 3200 LU/NLU converter you were running with the CPT66?? Only thing is that I still have the stock cam.Alot of guys like the 61 alot but if the CPT-66 has almost no lag at all maybe I should reconsider.

Try runnig your car with your current setup. There should be no problem to be in the mid 11's with your current combo set up properly. If thats your goals, then no need for a turbo upgrade.

I think your on the right track for a street turbo with the smaller turbos for superior spool. Unfortunately I've got hours of reading research but not hours of seat time research and I know everyone has an opinion but...I've talked to several people at Precision Turbos when my brother worked there. They talk to lots of customers on a daily basis. They have vendors who try just about every turbo made on the same car for baseline comparisons. The GT6162re is the one they recommended for me. For a street car they are hard to beat.

Now that I've got the improved long block on the way I could easily take on a bigger turbo. I'm selling the 6162re for the new billet 6262rs with the bigger inlet/outlet. They basically said the spool of the 6162 or the 6262 with the ball bearing it is just a blast to drive and provides pleanty of air to produce some great horsepower.

I'm putting my money on the 6262rs. In a couple of months I'll be able to give a more educated response from seat research.

I have a new th350 put in with a ptc 3200 NLU , the tune on my car allows me to run between 19.5 to 20.5 lbs of boost no problem on sunoco 93 only. low 11s with my car , at 22 lbs its like night and day . high tens for me at that boost easy. there's nothing wrong with the 44 , i would get the car running down the track with that 1st , mid 11's should be pretty easy with it . i like both the 66 and 61 , but if i want to turn the boost up with c-16 should go 10.30s easy. MY 66BB with my ported heads, intake, roller cam ,ect . the whole motor is also breathing alot better , so its a combination of all those things working together why my car has no lag i'm thinking

The Billet 62/65 BB FTW...
The 67/65 is great but how many of us need a low 10 second turbo?

Nobody NEEDS a 10 second turbo...:biggrin: :biggrin: :biggrin: :biggrin:

LOL I get your point.

What I am saying is that is putting a potential high 9 second turbo on a car that will likely not go faster than 11s may not always be the most effective approach. However I do understand buying a little bigger and growing into something as apposed to have to upgrade over and over again. This is the reason I put the 60/65lbs injectors on my stock turboed daily driver.

Baddest street turbo just came out, a Ball Bearing PTE 62/65 will be the new street king. It will spool faster than the BB67 and make more power until the very end of the power band where they will level off. Dyno graphs are out there of the two turbo's on the same car and it was clear as day that the new PTE turbo's are going to own.

New GT35 Killer Turbo - GT850R - evolutionm.net

AMS calls the BB67/76 a GT37R, the GT35R is a BB61/76 supposedly.

Graphs above are on a 2.0L motor so that 60mph power difference is very impressive. If that turbo can make over 120awhp more at 60mph on that low torque motor what will it do on ours??

Granted we won't push it too 9000-9500 but the 67 didn't catch up until then HP wise.

 

[ReaL99]

I don't know about the GT850R but I was talking about on the street as far as being the best Turbo.A CPT-66 might be a great turbo but I doubt it will hook on the street while the 61 Turbo with the right tires might be more stable on the street.Also its capable of 620 Horsepower and isn't overkill on the street.I can't say this with truth because I have never had or been in a car with a 61 or 66 but my TE-44 is fun but I think it needs a 3200 or 3000 aftermarket converter for my engine's application.Its ridiculous to get a over 700 horsepower Turbo only to be spinning or to have more lag unless the stall is high enough.

Any turbo with the right tires could be a great street turbo as long as you have enough mods to spool it.

I think you are missing the point, the new 62mm spools faster than the traditional 61 journal bearing turbo. I doubt PTE will even bother making a smaller turbo due to how fast these new ones spool compared to the old comp and turbine wheels, then throw in the new Boosted or HP turbine wheel relieves backpressure to make more power on the same sized wheel. Win Win!!

I have a TA49 and can't get it to hook with 295/50's, going smaller and having it spool even faster is pointless. It's now a Supra that needs to race from 55mph on so the tires stay under it.

So that being said, the new 62/65 will be the king of the street, spools like a 61 and makes power beyond the 67 until 9k.

Is the newest Turbo from Precision?? If it makes the power without having to run a 3400 NLU converter it probably will be a favorite.When I got my ESP cnc ported race heads and ported intake installed I should have installed a cam.The engine has 104,500 miles on it but burns no oil.I would think the 62/65 will be a bit more expensive then the 67.
