on a similar subject guys...how the hell do u launch these damn cars!! I've tried everything!!! I cant get the damn thing off the line, it either dies like u havent given it enuf revs or it diff bounces like a b1tch when u give it too many revs!! Im confused!! can sum1 elaborate on the technique!! thakns!
you give 60% throttle and briskly let out the clutch im not saying side step it and away you go. but if your tires suck you will spin em if you leave PSM on it will chop power its not your average car to launch

Hardest car ever to launch. Too little and you fall flat. Too much and you get anoying and potentially destructive wheel hop.

You will get type 2 ignitions logged in your ECU with high RPM and that can affect resale. Try to find someone who has done similar mods to what u plan to do and see how far up the RPM range it is still increasing power. Why go past that number?
With my flashed ECU, I''ve plotted RPM vs. engine load and torque falls off pretty badly after about 4500. I suspect the stock K16's won't make any power after 5500 or maybe less.

We offer the inlet piping with our own custom Hi-flow plenum (below) or with the modified OEM plenum. (less expensive). I prefer to upgrade the plenum, if you are doing this type of upgrade. It provides a smooth unrestricted path to the turbos, which is what this type of mod is all about.

Personally, I would not raise the redline above 7100 rpm's using stock internals. Back in 2003 we took ours to 7500 rpm's many times and I believe this was partially responsible for bending all six rods.
Heat becomes an issue. Your liner oil squirters are not sufficient and the lifters were not designed for 7500 rpm's.

Most small turbos do not even have anything to give up on top.. so its a waste of time....
Heck, a basic 18g is done at 6500... a K 24 sooner, a K16 even sooner...

I would personally not go above 7,000. After reading about Divex' car. I would have sworn he had RPM related issues? Don't quote me. I'm just going off forum memory.
I did have mine set at 7350 for a very brief time. The car is definitely a lot more usable in 1st gear.
One issue with these cars is that the engine outruns the tach. You will hit the stock limiter when the tach shows 6,000 RPM in 1st. It takes a mental adjustment so that you won't hit the limiter on a fast takeoff.

I'd say 7,400, max. But less is even better.

The only reason I can see one would do it is to deal with the short 1st and to better the top speed. My car hits the rev limiter at 326km/h (202.6mph) which then gently holds the car back. I guess if I would raise it to 7K, I would probably hit 335km/h - on the speedo of course. But then again; why? How often you drive up there?
