Got the mail in return, your mailbox is full, Mike. Rune

You have pictures on your mail. Rune

Got it. I have "pinged" him already.

Sorry, ping me????

Not a bad choice. Remember that Easter in Norway is a ski-ing period, it is very quite in town centers. On Thursday, Friday, Saturday, Sunday and Monday shops are closed, some days also pubs and bars. In Sweden, they have less "red" days when everything is closed. Sweds are less "religious" in that respect. I recommend Park Rica Hotel in Sandefjord, it`s very good, they have everything. You should take a trip by bus og train to Oslo, it takes 1,5 hour. Oslo is much larger and more lively. Call me if you come, my wife and I can guide you in town. If my car is ready, I can bring you back to Sandefjord. If you have a mailadress, I can send you some pictures of my project. Rune

Hi, that would be noce. Sandefjord is only 60 miles from Oslo. Easter is from 17. March this year, less than 2 months from now. My car is in a workshop in Lofoten, that is quite a bit of distance from Oslo. There is a chance that the car is not completed by then. Anyway it would be nice to see you, give me a call when your`re around, my number is +47 984 01812. Will you be bringing the white ZX?

Hi Mac 1: Could you help me with some advise regarding heads? Are you using original heads? If not, what is your choice? I have reached 710 BHP (engine BHP) on my 300ZX and want more. Using original heads but need to change this now. Have you any recommendations? Rune

Thanks Mike, very good. Have you been driving the stage 4-car for a long time ? Rune

This is very valuable advice, also regarding the 850 injectors. I have looked for 1000 cc, but can not find any. Can you help ? Will stage 4 on heads make the car drivable for the street? As I see it, the Tomei cams and non-hydraulic lifters will make the engine run on high RPM when idle. Is this correct or not? Do you know the maximum BHP you get with stage 4 and with stage 3? (I consider stage 3 as more appropriate for a 800-850 BHP-engine) Rune

Main ingredients: Pentroof exhaust manifolds Racing cats Turbonetic T04B/46 - BB-5 KKK10 (420 BHP each). To be increased to 530 BHP Border racing kit - 850 CC 3-plates ATS carbonclutch 1200 Nm capacity 2 petrol pumps: Original + 1 extra type Bosch, max 370 l/min. Double petrol pipes and 500 l. Filter Front intercooler. Air capasity 975 HP Engine Management : MOTEC JE - Forged Pistons EAGLE - H Beam Con-Rod Set (aircraft-steel type SAE 4340)

Thanks a lot, these heads make sense. Have you tried these yourself, or do you know anyone who has? I have burned lots of money on parts not proven, so I like to be careful. I am now increasing from Turbonetics 2x420 BHP to 2x530 BHP. Turbinehouse is the same in both versions, the compressor delivers 20% more air. Boost max 2,0 bar with the 420-turbos, probably down to 1,7 with the new ones. I know a workshop that can port the turbos, the exhaust-flow will be increased as backpressure now starts to exceed the turbopressure from 6000 rpm. Exhaustflow can increase by 10-20%, and that is what I need to run up to 7000 rpm without backpressure problems. The front cooler has a capacity of 1000 BHP, so that won`t be any bottleneck.

If you have 30-40K at your disposal, you can get 600-700 BHP if that is within your definition of supercharge. Simply said, you need to change almost everything in your engine. I strongly advice you to find the best man you can get in UK for the job. There are many variables, and they need to fit together. There are many workshops who claim they can do it. Ask for references !! Do NOT go for an "expert" without references. And be patient. A lot of money and parience are the main ingrediences.

Yea, but there is more than that, springs, cams, porting......

I would be more than happy........using my private mail??

Internals take the power produced by the turbos distributed by the heads. So the heads is my bottleneck right now. Everything else is in place - after 2-3 years and a fortune.

Excellent, thanks. Perhaps a stupid question, but how do you insert pictures?

Even the best engine builder would need trial and errors. This is terribly expencive for heads. There must be someone out there who has done this before......

Correct. All internals are changed.

I`ve spent a fortune, but my engine builder is perhaps the best in Europe on turbo engines. He has built engines since late 70`s. Everything except the heads are changed. By opening up the engine after 10.000 km drive, there were clear indications that the valves had had a tough time. I am impressed that the heads manage this level, but it will not last.

Thanks, I`ll contact him. :hyper:

Good comment, the HP-limit is probably close, and I don`t sleep well. So far 10.000 km (6000 miles) without any trouble.

Som far I am using original heads, valves and springs. By going further, I need expertice what to change.

Yes, 710 BHP and torque 850 Nm/640 lbs .
