New to www.calaisturbo.com.au? (http://www.calaisturbo.com.au?) Want a rough idea on what mods can be done and for how many dollars? Read on..... VL Turbo's are relatively easy to gain power upgrades with minimal cost and effort. If you are new to the VL Turbo scene here are a few modifications you should look at and the power range you will achieve. Note, these are rough estimates only. Performing modifications does not guarantee power rating. Every dyno will read differently, the best and most accurate way or measuring power is on the quarter mile. Basic Modifications: - 3 Inch exhaust from turbo back - Front mount Intercooler - Adjustable boost control - K & N Panel filter You will be looking at about the $1000 mark for something like this. It is always recomended when increasing boost levels past factory levels to have the car put on a dyno to check Air : Fuel ratios. Further modifications for power in the 200 rwKw – 230rwKw range - Aftermarket ECU example link or microtech to remove AFM. - Larger injectors for example 444cc up to 600cc - Highflow T3/T4 turbo - Larger fuel pump like a 984 or 044 - TX1/TX2 cam shaft upgrade You will be looking at around the $2500 mark. Prices indicative of parts only not labor. For Labor prices you are best advised to contact your local workshop for an accurate quote. 250rwKw + Range - Aftermarket ECU for example microtech, motec, Vipec, Link ect - GT35/40 turbo - Port and Polish head - TX2 cam as minimum (or equivalent) - Rebuild bottom end if needed with forged pistons. - Surge tank and 044 pump - 600cc injectors as minimum - Adjustable fuel regulator - Appropriate gearbox to suit (Auto manualised ect, Manual with HD+ Clutch) - Rebuilt VL Turbo diff Price will range anywhere from $6000-$12000 depending on new or used parts. The gearbox will be your most expensive item if you are wanting a built auto. They range around $3500-$5000 for the box, converter and tail shaft. Obviously costs are rough only, you will be able to do it more cheaply using second hand parts and doing your own labor. Always remember though, the poor man pays twice! If anyone has any suggestions to add to this post feel free to add them below.

The K&N filter by itself wouldnt do much, you really need to open up the air box or go through the guard with a hole saw.

best car to look at for bang for buck is mkdjet berlina turbo head has not even been off the car !! they removed the engine mount bolts and jacket the car up to change the cam!!! (jacking the car up lets the cam clear the rad support) i will post up a detailed thread on bang for buck very soon the motor is at the engine builders now but the build is at 6k at the moment including purches of car AND 3 speed KEAS jatco(og paul from keas) some basic stats on the car are ltx10, 1000cc 2x044 custom wade cam (1147 but changed slightly) also had to buy a 28 spline lsd billet fuel rail aiming for 10's with the car Some original photos have not been recovered yet.
