I have TurboXS stage 4 sitting in my room (vf34, sti pinks, walbro fp, full exhaust, Utec). I was wondering if, since i have the upgraded turbo, that the i/c hoses be a better mod than the pulley? Even if the hp gains are the same, wouldn't the hoses stress the turbo less? I understand a pulley is supposed to add even more hp with modded engines...any suggestions?

 

Both are great mods but for what you have I would say the I/C hoses would probably help a little more. I hope you are doing the uppipe as well =) ....... anyways why not do both as they are on the cheaper end of mods. I have a lightened Vishnu underdrive pulley with belts if you are interested and new hoses are only $120 shipped and second hand ones are cheaper ....

PM me if you are interested ...

 

I would also go for the I/C hoses.

 

i third them ^^^^ go wih the i/c hoses, get better airflow and get rid of that nastyass restrictive stock one

 

ic hoses make a big difference with the vf34, I went with the perrin set. it actually fits the vf34 better than the stock hose. i wouldn't even bother with the bov bypass hose as it's a major PITA. i didn't even put on the throttle body hose, just the y hose.

 

how hard is it to install the pulley?

 

Pulley is very easy to install 30mins max ....

 

Go with the hoses. The pulleys just scare me, too many questions that are still unanswered.

pscyho

 

+1 for hoses.

 

I know for a fact that the Perrin lightweight pulley does improve throttle response, but since the stock pulley is rubber-isolated, I wouldn't mess with it.

Messing with your pulleys and Flywheels can cause probs with your crank bearings in time.

 

I had the pulley in my hand, and last minute took them back and got ic and maf hoses. Same reason as above. Too many unanswered questions.

 

Go for the I/C hoses. Lightweight pulleys, like lightened flywheels, have been known to sometimes trigger cylinder misfire codes on the stock ECU.
