i dont understand how a th400 would ruin this car
final drive ratio of a TH400 is HORRID for a car like ours. Anything that has a high powerband is going to run like complete shit with it. Mainly people have good results with them is they are running smaller turbos which put them in the spot they want to be with a th400. with my 4r70w i have a steeper final drive and i can utilize my powerband better which is why im making over 1200rw with a 4R is its more suited for my setup. :beer:why is that? everyone else is running th400s and have nothing but GREAT things to say about it..
i appreciate the response, but would love to hear why you say so
thanks!
correct, anything under 4500 in my car it was slow as shit, as soon as you hit 5000 the car would instantly redline and practically lift the front of the car off the ground! For a street car this would bother me as its too late in the powerband, but since its for minimal street use it doesnt bother me, it will be a complete ANIMAL at the track. :rockon:How small of a housing can you get on a 67mm turbo? Even if you could get a .48 a/r housing, going down from a .68 isn't worth the money IMO. You might as well invest/trade for smaller turbos. An auto might make it better but it still is not going to make it's potential power until late in the RPM band. These turbos are HUGE! You figure guys are making 700+rwhp with ONE of these. The car would be much more driveable with smaller turbos. Why have turbos this big unless you are racing it and planning on making over 1200-1300rwhp. Just my opinion.

Dude, your car is going to fly with an auto!In my opinion, you will see the greatest benefit by switching to an automatic.
Whatever flavor you choose will be rewarding (Turbo 400 or 4R70W).
If you want overdrive the 4R70 gets the nod.
If not, then get the 400.
I have driven cars that had twins and a stick and twins with an auto.
The difference is unbelieveable.
The auto combo spools much better and decreases lag....period.
I am in the process of converting my Saleen over to an auto (4R70) for the same reason (well that and breaking Viper-spec T56 parts like toothpicks).
Don't change your turbos!

Im getting the feeling that I need smaller turbos and a th400. this car might see the track a couple times a year but 90% of the time(only weekends) itll be on the street...
Now I need to decide on turbos.. ahh where to begin! I want quick spool and high hp! I loved how my twin 57s felt with the 281..
anyone wanna trade turbos
anyone wanna trade turbos
Or transmissions? lol
buddy james has twin 67's on his car its a 302ci motor and a manual and his car is fast...
