I HAVE A 91 TALON TSI FWD. I HAVE ALL OF THE BOLT ON MODS AS FAR AS 3" TURBO BACK EXHAUST W/TESTPIPE, K&N WITH FREE MODS, DAVE BRODE UIP W/2.5"THROTTLEBODY ELBOW, SUPRA SMIC, WALBRO 255LPH FUEL PUMP REWIRED, STRUTS, SPRING AND 17" WHEELS . WILL A SMALL 16G PORTED REALLY MAKE THAT MUCH DIFFERENCE? WILL I BE ABLE TO TELL THE DIFFERENCE IN PERFORMANCE? OR SHOULD I GO WITH A PORTED BIG 16G? LIMITED TRACTION, WHAT ARE YOUR SUGGESTIONS?

HELP PLEASE

THANKS
JEREMY

the 16G turbos are an improvement over the 14b. I can't remember exact cfm flow specs and am too lazy to look them up right now Basically you will notice an increase in your power over all mostly at the top end. The 14b is an excellent turbo for the 12s in 1G AWDs probably low 13s in FWDs(guessing). The big 16G flows more than the small 16G by quite a bit but it does lag a tad more. Supposedly this will be nearly un-noticable if you port your manifold and 02 sensor housing. You will experience more traction problems though because you will be adding more power to a FWD which even stock tend to be able to brake the tires loose. I guess big or small 16G depends ultimately on your goals and how concerned you are about lag. Hope this helps.

About 100cfm if I remember right, when I put mmine on I noticed a pretty big difference.

I for one noticed minimal gains when upgrading from my ported 14B to my small 16G. What ever gains were gained occur once the car reaches 16psi and beyond. I also had complete intake and exhaust upgrades at the time. If I had to do it over again I would have installed an AFC before upgrading the turbo. I think I would have gained more power by properly tuning my A/F ratio.

T-25 320cfm at 15psi
14b 405cfm at 15psi (i think)
16g 505cfm at 15psi
Big 16g 550cfm at 15psi
20g 620cfm at 15psi (i think)

You'd probably be better off getting a 20g so you have the lag to help with the traction.

Not really, lag only makes traction problems worse and it's harder to drive consistently. That's why people have an easier time launching high powered rear-wheel drive cars than high powered turbo cars because they have an "explosion" of power. A 20G would make this phenomenon worse rather than better.

Exactly, a 20g will make traction problems that much worst.
