Hi, I'm reasonably new here and been reading every page on the web i can find about my model and modifications i can find.
My B4 is the Rev A, it has the vf26/vf27 turbo combo (it's a manual). I've put some 4 pots on the front and a genome strut brace and that is it so far.
Now the tricky part, getting more hp. an exhaust and a piggy back is my train of thought, but i'd like to hear from others with experience (please don't suggest single turbo) as to how loud the exhaust will be and how reliable the engines can be expected to be after these mods (how much more stress on the engine and where?).
a 255 lph walbro is also on the shopping list.
I've been looking at a rage 2.5" system turbo back, (twin 2.5" dump pipes, 2.5" y-pipe, 2.5" back to muffler), I want to know if other people have run similar and what they would do differently (the aim is more usable hp without to much noise), i.e, would you have another resonator in it? magoo muffler in chch here said to expect $1200 for said system.
For a piggyback i'm keen on an hks f-con. i know these are probably on the expensive side but i've only heard good things about them (i know they can only be tuned by hks dealers...) and i do need this car to be reliable (understanding regular maintenance is always necessary). if you have any other suggestions on a piggyback that can handle the twin turbos i'm listening
I've found the guys on ozliberty were getting 200-220kw at the wheels with similar sort of stuff but haven't heard how long these cars last and where they crap out, i understand the single turbos put out this sort of power reliably (? am i wrong here) on standard internals so where is the weak point in the twin.
also will the hks f-con be able to control boost? i haven't heard if they can, if they can that's great but otherwise i'll probably need a boost controller (won't i?)
thanks guys
