Bosch 440 Injectors

[TSTUBB]

Looking at getting a Stage 2 tune from a place near St.Paul called United MotorSports (Further Performance). They want $440 for there Bosch injectors but eurocustoms.com has them for $269http://eurocustomstuning.com/catalog/product_info.php?products_id=92&osCsid=a501c7b3105 2bdca17544d5002c844e5

Aren't they the same? And do I need a upgraded intake or blow off valve for stage 2? some say yes, others say no.

match part numbers for the injectors- manufactures part number, not retail part number. if they're cheaper then hell yeah buy them. I think what you are seeing is just the higher priced injectors were either originally bought by the company for a high price and they can't make a good profit range if they sell them low or they are just ripping you off. the low priced ones you'll be fine as long as you do your homework and find part numbers and such, a deals a deal. what makes the deal a good deal is how much you know...did you do your homework.

your car will benefit from an upgraded DIVERTER VALVE--forge 007 or Bosch 710n are the most popular--not a BOV. our ECU's are too sensitive and the ECU will pick up on the lack of air in the system. this will cause problems. an upgraded intake as in before compressor? our air boxes are very efficient. keep the air box but upgrade the TurboInletPipe. do not get the ER TIP, I have it and do not like it just for the fact that it slips off because of the lube from my DV, no other problems tho. get a silicone TIP- forge, apr, samcro.

if you want a cone filter (cold air intake) you NEED to fabricate a heat shield to block the turbo/manifold heat levels. all the cone filter will do at stage 2 is amplify your turbo and diverter valve. it's not like you need it since you are not out-flowing the stock air box or because you need to re route your TIP for the big turbo.

a little searching can answer pretty much every question you have.

The stock airbox is a true "cold air intake" as it is completely sealed off from the engine bay (inches away from a turbo and cat - extreme heat) and draws air from outside the engine bay - snorkel and fender.

A cone on the MAF is a HOT air intake. Drop in a high flow panel filter and call it a day.
