Yes, we read this, and there is so much to know, and so much mistakes !

compare to N42 stock and my P90 ported 40 mm intake and ported exhaust too.

Good job, man , but you would prep your rockers like the one in the third picture ! lighter at the lash pad for revs !

very funny post here , guys." I tell you my story : I have made my own Idler gear kameari system "just for the fun, it cost me 100 €uros ! i'm sure it will do nothing with power increase ! only to be able to say : i did it ! I will put an Australian electric water pump " Davis Craig " Just for the fun, it cost me 150 Euros, i'm sure it will do nothing for power, may be , just expecting a better cooling with mods on my head ( holes above the exhaust ports ) and i'll try reverse flow just to see. I can come back to original mount. I hope for the best advance ignition and good power, but i know it's not only with these mods !

No more pictures, but it's the same thing that a Kameari : sliding double gears in an aluminium alloy piece , ball bearings ( not spin rollers ) and oil jet on the lower gears. Hope that helps !

funny post around technical considerations ! i have many respect for Peter and also for A thomas, so for me , it's a real dilemme ! both have arguments ! i did'nt want to waste my money ( ) so i made my own idler gear system ! see photos down here! as far as power is concerned, i don't know;;;;;;;, my engine is stil waiting for my restotation to be finished. I'm making a davis craig EWP mount with reverse flow, and i made changes in the water distribution in the head ( without knowing Peter made something like this ) I think the power loss was more a temp issue in the head , leading to reduce ignition advance , and not the Kameari system. A friend here in France, with a Rebello engine has no problem with the K gear. ( just noisy ) congrats to PMC and hs30 , good guys ! don't leave us ! regards Didier excuse my english !

why always the 5th ? cooling temp ? ,oil pressure, ?

If you have your MS3 soldered, you don't need the EDIS system, you can make a COP ingnition system and sequential injection by the way. and like Lazeum said : don't use brute force !!

You make a 6/1exhaust and not 6/2/1 ? what is the ID in mm of the header? 48? Good job, Peter Didier

on Ebay motors, you get some choice ! http://motors.shop.ebay.com/i.html?_nkw=obx%20lsd&_dmpt=Motors_Car_Truck_Parts_Accessories&_fln=1&_fpos=Zip%20Code&_fspt=1&_sadis=2000&_ssov=1&_trksid=p4506.c0.m282&Make=Nissan

It's what i made with my fluid damper, , it's a removable solution, even if you can tune the trigger angle in the firmware,you can still change the gap by re drilling . Welding is a good option , spots don't overheat the damper, but it's not so clean

Good job, Peter, but i'm wondering what is the upper aluminium tube for ? no connection with each exhaust port, connecting to the head rear side ? No reverse flow i think . so what ? well done , but sorry i don't like turbos . forgive me ! excuse my language !

Extrudabody is a good product, Jenvey , too, but Electromotive ECU has nothing better than Mégasquirt2 or 3 . If you really want the best without price consideration, go with MOTEC,world leader in racing .

Do you mean it's easier to tune DCOE's ? and you get three X 2= 6 problems ! No headache with MS if you start with good basics, you can tune in alphaN or Speed density , or a mix, but tip in issues only occur with wrong AE or x tau tune .

Hi, Peter your water system is "Fantastic" ! awesome, super cool and beautiful, much better than my "amateur" build ! do you make a " reverse flow" system or classic ? http://forums.hybridz.org/uploads/monthly_06_2012/post-5139-098130700%201340667524.jpg

Yes, you should go to fluid damper, it's a safe solution for high revs, but even if your actual damper slipped, your timing with the crank gear is still in place, with 56° your engine would knock or stop !

You're right, duragg, go to GSXR and Mégasquirt, it's no headache at all !

Thanks for your knowledge, i'll keep it in my mind when the engine will start, Didier

Yes, i shall make tests with reverse and classic flow ,it is very easy to fix , and i know the EP will not produce 3 bars at maximum power, but there is advantage to get a constant flow without cavitation, and you can keep the pump running after shuting off the engine, it is a good thing for a progressive cooling down . ( right ? Photos showing the water distribution holes in the head,above each exhaust port, and the big tube coming from the pump in the reverse system, or collecting in the normal flow direction .( who knows ?) regards Didier 260 Z 2+2 modified (just a little )

Where did you get your fuel tank ? and how to bring it to France ? (shipping cost ?) salut, diz9 , moi c'est nissag250 ...

With an electric water pump, i'll drive with megasquirt and pulse width, no need for a thermostat .

Well, if you come for vacation in France, you"ll can see others 3.0l engines build !

I'm building a reverse flow system too, i drilled above each exhaust port, and with a Davis Craig pump, it's easy to control the flow.Two restricted hoses in the upper pockets of the head will evacuate the gazeous bubbles to the expanding tank. i answered to your message, Peter Didier Do you know this patent ? http://www.google.no/patents/US5255636
