B234 kolv i CAD

Does anyone have cad file on the valve reliefs on the 16v pistons? I have modelled the piston head once, but the file seems to be missing, and I can't access my old notes or file on server where I've save everything... I thought that I could do my new pistons with CNC mill at work.. If you can provi...

Re: Compound turbo system sizing 2JZ

Thanks AL At first I thought that the moust important thing at least if owerall performance is conserned on the setup is the flow capacity of the 50mm wg + exhausthousing/turbine on the HP turbo, and secondly the size of the LP turbo compressor. How about the boost control of the turbos? There will(...

Re: Compound turbo system sizing 2JZ

I were driven around in bmw 535 sport D that has the large/small turbo setup... It made me want to try the compound on this engine. I love the instant boost of small turbo, but if you do 2jz (or om606) on for example volvo 244 in my mind this type setup demands some serious punch. Big Al: you are co...

Re: Experiment: B23 med Turbo och Kompressor

http://m.ebay.com/itm/271900905622 This bypass valve will work as well if you don't have valve on charger itself. It will allow you to run the charger all the time without pumping air back to the atmosphere like you do with conventional dump valve. This way you reduce the noise that charger makes, ...

Re: Experiment: B23 med Turbo och Kompressor

I think you should forget the magnetic coupler... Better choise would be bybass valve that is atleast on the eaton mp90. It will let the engine breathe naturally when you are riding it with underpressure area(= nearly closed throttle body). When the you open the throttle body the valve closes with p...

Re: Compound turbo system sizing 2JZ

I know that single turbo is a different animal compared to compound.
I think that if his experiences with 2jz are that exhaust side is more restricting than inlet side he is going to recommend to improve the exhaust side at the same time when engine is dismantled to pieces.

Re: Experiment: B23 med Turbo och Kompressor

Go with HX55
Both have same compressor, but the turbine of the hx50 doesn't produce enought power to take the kompressor to it's limits. Spool wount be the issue because eaton does the work on the lower rpm range.

Re: Compound turbo system sizing 2JZ

My friend told me to port the exhaust side if I use gte head. He has no experience with ge heads. In he's opinion I should get allso the cams changed or welded/reground. He has quite a lot experience in building turbos for race cars... often he has to change larger exhaust housings for supra guys to...
