I wanted a cam slightly more agressive than the 119 without losing idle quality.I´m hoping it will be a bit more snappy and faster on spool up.My original choice was the 163 but the 86a runs much smoother and I believe it is a better cam for a 2 liter.If I was to build a 2.4 turbo I would go with a 163 on a 110LC.

Thanks Clive for the info! I don´t mind a car that is a bit harsh.It´s a car made for for fun so some comprimises have to be made.My main focus is stability,safety and driveability.I´ll sacrifice some comfort in exchange.I got to drive a Lotus Elise this summer and the car´s handling really impressed me.So easy and precise and stable.It´s probably not possible, but f I can get near that kind of handling I´ll be happy.

A little update on the 2 liter turbo project.I´m back from vacation and picked up my parts from Remmele.

The heads are also finsished but I have sold them.Instead Remmele is going to do me up a set of CU heads.I´ve decided to go with the CU heads for a couple of reasons.First - more flow,more meat in the chamber and ports along with larger ports.I will be using 45x39 valves and dual springs 130Kg.The exhaust valves will be Mercedes 7mm stem sodium filled.The intake valve is a Remmele valve.Another reason is there´s more surface to seal for the header in the square port than the oval port.
I will more than likely use the BAS stainless header like Wally.Yes - I am a copy cat in this case.What convinced me is that Wally is now using a GT3076 Turbo and it fits in the same location as the old turbo which was considerably smaller.But Wally´persistance and 350HP don´t have anything to do with it

The crank and rods are also here - but no need to show that since they are completely stock - just well balanced.
3.5 kg Flywheel - including surface rust...I need to clean it up

Good looking parts Mark!

Thats quite a change in thought Mark! I can remember you critising my BAS header choice wrt strength and diameter...
And I copied it from Sandeep you know.
Well, better well copied than ill made

My bug may be sporting a ducktail with air-air intercooler spring 2010 . I'm pretty sure that 350 HP / GT3076R had nothing to do with it ...

Just checked webcamshafts website and I think the valve lift of the 86a is too small (11.05mm). Turbo's love valve lift is my current experience.
There's probably a reason Webcam advertises their 119 as a turbo cam...
I would advise to change the cam to one with about half an inch lift (12,7mm)
1.7mm lift difference is A LOT!

Just my 0.02 cents worth of friendly advise
