Converters respond to power period.
Our platforms will not go fast or have power on tap with bigger turbos and super tight converters.
These motors cant move the air at very low rpm.
A tcc clutch is a wear item no matter what its made out of.
We have worn out Kevlar clutches in wot situations on the dragstrip and street on high end converters.
Why many go non lock.
Ya kinda say right there.
5.0 1st
Now pulling rear gear would really need way below a 3.08
So the rear doesnt help the car at all.
This tranny is not for the buick world
But one can put anything in anything with enough money.
Your research should not of lead you to old cast wheel journal bearing turbos.
There are billet wheel turbos in bb even triple bb without hubs these days.
Also converter teck has come so far.
2800 rpm is not the right stall for the turbos you have chosen above.
You are wasting your time and money until you your over 25+psi on the stock turbo
In fact,you will slow down with these turbos as they will not spool as fast unless the the converter is real loose.
A d5 stock converter was just a fast on the stock turbo/intercooler/motor as upgraded converters...
Im going to highly advise you to not buy anything for the car until your ready to do the transmission.
A shift kit will help it live a little longer but I can go at anytime.
The stock turbo will make depending air quality
30psi of boost.
It will make 500lbft of torque. At very low rpm as well...
Thats alot of changes but the right way.
Log looked good?
New converter had a positive effect on rpm drop?
When you say locked are you force locking a single disk diode?
