N12 Turbo Forums

... Cherry Turbo N12 (as it is called in Europe). Im considering installing a head from a E15S, on my E15ET block. From what I could see parts on valves, valve rockers etc.. everything.. is the same, so should work? Then I found this nice article: http://forum.n12turbo.com/viewtopic.php?t=4613&highlight=head ...

... would have been gone after fitting new stem seals, namely these: http://www.onlinecarparts.co.uk/reinz-7440095.html I mounted them with the valves staying in the head and pressurized cylinder, but noticed, that they would start to to slip off the valve guide a bit, soon after they were seated ...

... combo (in my opinion) would be the NA E15 rods in a E16 block with E16 crank. Top them with some GA16 pistons, they will need flycuts to clear the valves, and you have your 10:1+ compression. The chambers on the E16 head will potentially give a better squish with the GA flat top pistons also. Damo

... have photos Back from the dead!!! Haha. Wow this took alot longer than i expected. Here is the list of mods: Ported and polished head, over sized valves and springs. Camtech reground mild-lumpy cam Block bored out 40 thou Custom 40 thou over size forged pistons Custom forged rods Fully balanced ...

Oh, youll have to wait and see on that one. The connection is; Airfilter > AFM > Idle Valves > Turbo > Intercooler > TB/Plenum/manifold. Drivers side Rocker cover vent plumbs between AFM and turbo Passengers side Rocker cover vent plumbs to plenum via a PCV valve. ...

... dry, not sure this would have caused it; battery? figured it would have had more of a dying away affect rather than a halt? A friend suggested the valves could be stuck, but would the engine still have cranked initially when i was building oil pressure under no load? Help Appreciated!! Cheers, ...

Good point. The inlet manifold gaskets are the same for the E15/E15T/E16 the oval shape, where the E13 has the round port shape. Again, they will all be in a standard kit.
Also, out of interest Denied, the E15T has 1mm bigger exhaust valves over the NA E15.

... timing light today so i'll be able to set the timing when its ready to go. Will be sure to double check the cam belt and do a cold hot set on the valves ;) The dizzy is still in its initial position from before i think slightly towards the front of the car (to retard timing?) so ill just leave ...

... "told" about an engine being built some years ago. Just assume its never been setup and so NOT ready to go. Just do a cold set on the valves before you start it and a hot set after and youll know for sure yer? Disconnecting the CAS will just prevent the ecu from firing the injectors ...

... rpm for no longer that 8 to 10 minutes at very most. Drop it back to idle speed and recheck ignition timing. Shut it off and do a hot set on the valves anf give every hose clamp a check tighten and your ready to rock. Now, out you go and enjoy your engine and dont BABY it. Just drive it like ...

... engine, agreed with Evan that i would need to create a new gasket to put in place. the other problem related to this was that i have caused the valves to need readjusting hence the cam being locked up so for $250 he will readjust the valves and fit the timing belt, whilst letting me look on ...

turn the crank back to 17c btbc, if I read it right you're got the pully mark on 0,if so the pistons are hitting the valves

... that problem. belt off, line up the timing, get the timing right. belt back on and tensioned correctly, double check spark plug holes to make sure valves not off. go to rotate the crank by hand and it moves smoothly a split second then jumps teeth on the belt so i go and check to the cam shaft ...

Ahh. Ok, EGI plenums dont have those valves the stock logs do apart from the AAIV on the end of the plenum
.
Connect switched 12v to that black housing on the end. Its identical in operation to the one on the stock log.

The other idle compensation valves live on the stock EGI throttle body.

Hi Guys, looking at the egi manifold that im going to be installing it the following weeks it appears that the valves for the speed idle compensators are blocked off. Just wondering if this is an issue or is the compensator superfluous?

Cheers,

Reuben.
