I have a GT-6776s now and I really like the turbo but I had a 45a on my last car with a near identical combo and the 45a pulled harder and went faster. In all fainess I did have more time to refine the 45a combo so I may be able to match its performance with the 67 I currently have with more time but my 45a went 130mph in the quarter with a full weight T-Type with a pretty basic combo which will be tough to beat.
p-67 bb or 45a turbo

What stall did you have on the 45a? which stall do you have now?
I had a 3400 Vigilante with both turbos. The spool up with the non-BB 67 and the 3400 is great, couldn't ask for better. The first time I spooled it up at the track it spooled so fast I thought something was wrong!
The 67 is easier to spool and lauch off the foot brake but so far just doesn't have the mph potential of the 45A in my appliaction. Both my cars have/had stock uported intakes, stock TB's and sotck valves and mild flat tappet cams. The T with the 45a went a best of 10.61 @129.7 on drag radials, while the WE4 with the 67 has gone a best so far of 10.91 @125.4 also on drag radials. I do feel the WE4/67 has more potential in it and it may end up running just as well when it is all said and done but picking up an additional 5 mph will be pretty tough. I think it all depends on your combo. If you have GN1's, and good flowing intake and other parts like that the 67 is probably equal or maybe superior but the the 45a just works well to push thru stock junk like I have. :biggrin:

Supra junk is slooww!!!!
whats up Tommy how do you like your 45
pulls hard as hell for stock intake and heads, lots harder than the ol 54
In the last 3 years ive seen at least 5 go 130+mph and none of those went quicker than 11.40. You can lol all you want but im only reporting what ive seen. Maybe the drivers sucked or they were all taking it easy out of the hole?

Would a boost controller help the 45a spooler a little faster? I got champion iron's and champion ported intake. just looking for the best turbo for my combo.
Possibly. I have never run anything other than the hardware store style bleeder valves. I have heard some good reports on the RJC boost controller valve. It's cheap and its a proven concept. As a matter of fact I have a brand new unused RJC vlave that I would be willing to part with if you end up needing one. I fully planned to use it but my current set up works so well on the street I almost hate to mess with it. I am a little concerned that if the RJC valve works as well as it is supposed to my car may spool too fast and spin!
Let me know if you want to sell the rjc bleeder. I'll probably will need it.
I like my rjc bleeder easy to install and use here is some post on 67

went for a ride in a few buddies that have the dbb 66 and a dbb 67, man there is basically no lag at all with a right converter. I mean around a few tenths of a second MAYBE. And once it getts going those things pull pretty hard.
I'm just ready to break baby in! I got a long list of stuff just put on. Trying to get the best of my combo for turbo wise and the other stuff. It'll probably scare the sh$^ out of me when I drive it again. It want to break it in so I know what to expect from here.
