with a half bridge id start looking at larger hotsides than what the stock is...

in my opinion a hal bridge and a BB GT35R will put you right where you want to be. it'll spool up quick and hold. plus you have the option of turning up the boost and adding some alky into the mix for a fun weekend thats the road im looking at. except i just have a massive streetport.... didnt know as much about bp's when my engine was being built as i do now... i more than likely would have gone that route.

i want something i can drive daily and i'm not sure....

i'm still torn though, if i was keeping my T04R i would have no doubt on my mind to go half bridge, but since funds are lacking i have to go with a fairly large street port....

I really REALLY did not want to stick my nose in this one, but someone had to mention my name. :P

Seriously, to make statements like this, you're really ignorant on the subject matter.
Fuel consumption is directly related to BSFC.
You should look up the BSFC of BP's, especially at low RPM's.

I still think BP's should not be used on a street vehicle, but WTF do I know, right?

BTW, SP's should be hitting 25+ mpg on freeway cruise.
That's 50+ more miles per tank of gas versus your 22mpg.
With gas starting to edge to $4 and with potential to hit $5+ soon (think US invades Iran), this might be a significant factor...

GT35R is too small for a bridgeport. Think GT40R with a large hotside.

but is a 35r really to small for a HBP? i understand why it would be small for a full out BP, but i would think a 35r with a 1.05 hotside shoul work fine.. especially with the modestly ported "eyebrows" on HBP's ive seen. but i am by no means a turbo expert, if even novice at the subject. but most of my studying is towards my own setup.

I guess if you are looking for around 400 HP, then the GT35R would be fine. But if you only want to make 400HP, then a bridgeport is unnecessary as well. Stock or street ports will do it, with good response on that turbo.

More detail on that turbo is needed (is that .63 trim on the compressor, turbine, or 0.63 A/R?) but based on your PM, anything T3 is too small for a 13B. Especially when bridgeported.
