That's a bit of a difficult question. Are you going for looks or performance. If it's performance, of course you could have substituted some things. But to each his own right?ryno11 said:do you think those are good mods to start with?
It's unfortunate you thought that about the BOV. People get BOVs first so that they can mimic 2F2F, not because it prolongs the life of the turbo. I have no idea where you got that idea unless maybe you came from the Honda crowd where they run low boost usually and can sometimes get away with no BOV. All Evos already have a BOV. Getting an aftermarket one with no power mods and stock boost, especially that Greddy RS, is just a waste of money. Please don't get stuck in the rut of only buying namebrand stuff like Greddy. We have tons of parts from vendors not named Greddy or HKS that work incredibly well while costing much less. What's done is done, but you were definitely misinformed on the BOV. Same with the turbo timer - it's really just a gadget and is not needed on an oil-and-water-cooled turbo like ours. The gauge was a must, so you're good there.ryno11 said:unfortunately I already purchased the Greddy rs bov, greddy auto timer and greddy boost gauge. I went this route because I figured that these are things that will protect my investment. I made sure not to get the loud bov...not my style...but I read that bov's will prolong the life of your turbo (right). Timer to make sure the engine is cooling properly and gauge is self explanatory. I planned on waiting to add hp
You are WOT going into the parking lot, right up to your parking space? That is the only way your turbin housing would be glowing cherry red when you ar pulling into the parking lot!turbolarry said:BOV's, and in our case compressor bypass valves (CBV) do protect the turbo and keep boost from backing up to the turbo when thottle closes and reek havok on the bearing. So ultimately yes it protects it. It only really needs to be upgraded if you're going past stock boost levels or you got a leaky one. Since you already bought the Greddy one, you might as well put in in and have fun adjusting it.
Turbo timers might not technically be needed, but I like the piece of mind. I know I get my turbine housing cherry red pulling to the parking lot at work because I'm always running late and I'm not about to sit around for a minute or two. I definately don't want to open up the turbo and see this;
These are just cars, not an investment. In fact they are just money pits. :laugh:
As long as it's 3 inch consisdant diameter with minimal mandrel bends; get the style/sound that fits your budget. :thumb:ryno11 said:Thanks to all of those that gave me advice on my mods...especially BOVs. My next move is exhaust...recommendations anyone? anyone?
