Here is a list of available turbos for the Buick Turbo Regals. I have given a brief description on each turbo from what I have available. Always remember that you can't just bolt on a turbo and expect a miracle. As always it is an effective PACKAGE that makes good results, not a single item. The ET range is on the average TR. There are A LOT of people going A LOT faster than is posted here. I'm just showing the average results. Once again, just my opinion. .

Name	Description	ET/HP	Comments
TE-34	Non-stock appearing 3 bolt turbo 56mm compressor wheel Stock or blue top injectors stock or minimum stall converter	Flows 785 cfm 530 HP High 11s	I've used this turbo personally. Excellent for someone that wants to upgrade thier turbo from stock, but doesn't mind the non-stock appearance. Had a car go easy 12.20's with this turbo
TA-49	Stock appearing 3 bolt turbo 58mm compressor wheel Stock or blue top injectors stock or minimum stall converter	Flows 800 cfm 545 HP High 11s	This is the most popular upgrade for the turbo regal. It looks exactly like a stock turbo, except the larger inlet bell, and will go deep into the 11's with the right combo.
TE-44	Non-stock appearing 3 bolt turbo 58mm compressor wheel Stock or blue top injectors stock or minimum stall converter	Flows 850 cfm 580 HP Mid 11s	Very similar to the TA-49 only not stock appearing.
TE-60	Non-stock appearing 3 bolt turbo 60-1 compressor wheel Blue top or 009 injectors 2800 RPM stall converter	Flows 900 cfm 600 HP low 11s	This is one of my favorite turbos. I went 11.50's with this turbo at only 20lbs of boost. I have seen this turbo go low 11's on a friends car and have heard it going mid 10's. i really don't recommend anything less than a true 2800 stall.
TA-60	Stock appearing 3 bolt turbo 60-1 compressor wheel Blue top or 009 injectors 2800 minimum stall converter	Flows 830 cfm 565 HP Mid 11s	Very similar to the TE-60, but stock appearing.
TE-61	Non-stock appearing 3 bolt turbo 60-1 compressor wheel Blue top or 009 injectors 2800 stall converter	Flows 920 cfm 615 HP low 11s - high 10s
TA-61	Stock appearing 3 bolt turbo 60-1 compressor wheel Blue top - 009 injectors 2800 minimum stall converter	Flows 900 cfm 600 HP Low 11s-high 10s	This Turbo is a real popular upgrade also. It's got the same turbine wheel as the TE-62, with the same compressor wheel as the TE-60. An excellent alternative choice to those that want to keep the "stock" look
TE-62	Non-stock appearing 3 bolt turbo 60-1 compressor wheel 009 - 55# injectors 2800-3200 stall converter	Flows 935 cfm 630 HP Low 11s -high 10s	This is a very streetable turbo. Kinda got a bad rap due to bearing failures, but it a excellent turbo. It has the biggest combination of compressor and turbine wheel avalible with the "stock" type CENTER section.
TA-62	Non-stock appearing 3 bolt turbo 60-1 compressor wheel 009- 55# injectors 2800-3200 stall converter	Flows 915 cfm 615 HP Low 11s- high 10s	Stock appearing version of the TE-62
TE-63E (TE-45)	Non-stock appearing 3 bolt turbo 63mm compressor wheel 009- 55# injectors 3200 stall converter P trim turbine	Flows 950 cfm 680 HP High 10s	I have this turbo on my car right now. It pulls like mad and has very little lag. You need a good 3200 convertor for this turbo.It utilizes the "big bearing" design, and has a full P-trim turbine wheel.
TE-63-1	Non-stock appearing (large compressor housing) 3 bolt turbo 63mm compressor wheel 009- 55# injectors 3200 stall converter	Flows 970 cfm 715 HP High 10s
TE-63	Non-stock appearing (large compressor housing) 4 bolt turbo 63mm compressor wheel 55# injectors 3200 stall converter	Flows 1100 cfm 745 HP Mid 10s - low 10s
TE-69	Non-stock appearing (large compressor housing) 4 bolt turbo 67mm compressor wheel 55# injectors 3500 stall converter	Flows 1165 cfm 780 HP Low 10s - high 9s
PT-70	Non-stock appearing (large compressor housing) 4 bolt turbo ?mm compressor wheel Big injectors 3600 stall converter	Flows 1220 cfm 830 HP Low 10s - high 9s

This is about as far as I can go. All the above is correct to the best of my knowledge. I hope this will be benifical to someone planning a Turbo upgrade. Please keep in mind that a larger Turbo is only one part of the "package". It takes a well thought out plan to make a TR exceptionally fast.
