What is better a boost controller or a turbo timer. I know that the boost cont. is to increase ur psi. But what is the timer for?

Keeps the car running for 1-10 minuets after you turn it off.

Cools down the turbo so the oil doesn't bake into the turbo and break it. Can't remember if it cycles coolant or oil through the turbo.

Two totally different things for different purposes.

A turbo timer you really don't need. If you have a water-cooled turbo (which most cars do), you can be safe by taking the time to sit in the car for a few minutes while the turbo cools (this is ONLY after racing it). Otherwise, with normal driving, you don't need to let it cool..the coolant will do it when you turn the car off.

You can easily blow your engine and/or turbo to pieces with a boost controller if you don't know what you are doing.

The turbo timer is a nice convenience if you tend to race around town and don't have time to let your engine cool down before you shut it down (ie. if you are often running late to work or school, etc.). Otherwise, it doesn't really have much value IMO, but it IS one of those inexpensive mods that looks slick and can't hurt anything.

I highly recommend a K&N air filter if you don't have one yet. Sure, it's more expensive than the stock filters, but it lasts 10 years and will give you a bit more HP and maybe even a bit better gas mileage.

Does anyone have the Blitz Dual Turbo Timer? I need to get a better boost gauge and that one has a digital one. Does it read in PSI or kg?

Yes. My TII has both. Note that you should get an FCD if you install a boost controller.

Here are my TII mods (I bought the car this way):
HKS Turbo Timer
HKS Variable Boost Controller
HKS Super Mega Flow Intake
Racing Beat Fuel Cut Defenser
Straight-Through Cat-Back Exhaust (no mufflers)
Gutted Pre-cat
Auto Meter Ultra-Lite Pillar-Mount Boost Gauge
Best 1/4 mi: 13.6

don't bother getting a boost controler if you don't have any other mods. you will just ruin your engine. start with a full tune up and get your car running perfect first. thats most important. Then learn about your car before you start spending all your $$. It'll last longer and cost less in the end.
