dyno'd my Turbo 3.1/5-speed '91 Cutlass

you can get a t25/40 I think from ATP turbo. Uses the stock exh side but a larger intake side so you can spin it slower and have cooler charge, but push more cfm for more power.

just go to www.ATPturbo.com and take a look at there turbos. THey hve stuff that will bolt to the stock crossover and give more airflow.

not sure if this will work. Its the 25/40R and goes for $1k. Will bolt to stock crossover butmight need to make a new downpipe as its a 5 bolt discharge and I dont' know what stock is.





Dual Ball Bearing GT25/40-R Turbo assembly with specified ar. T25 style inlet flange with 5 bolt style exit. Large 60- 1 style compressor housing with 4.00" inlet and 2.50" outlet. Very Good response turbo for 4 Cyl applications. This turbo has a flow capacity of about 450HP.

i've thought about going with going with another turbo with a T25 style turbine housing, but they are so much more expensive than the T3/T04E. i'm not sure what i will do yet. i could use my use my current crossover pipe with the Disco Potato or bigger, but then again the T3/T04E costs alot less than those ball bearing turbos.

there are alot of things i need to do before seriously thinking about a turbo upgrade though. i have a complete LG5 sitting in my garage that needs to be rebuilt, and this high mileage turbocharged LH0 i'm using now might not like more power :P
