Turbo head has more agresive cams, or you can say the valves open higher
i was thinking and a friend of mine said he dont really know so i wanted to know if there is any change with the nt head vs a turbo head..
Turbo head has more agresive cams, or you can say the valves open higher
NT and Turbo heads are the same..except for the 4g61/4g67 which have smaller combustion chambers. Turbo cams are not the most aggressive, the 94 Galant GS cams are most aggressive OEM cams known to man.
94 Galant GS: 4G67 head, 1G IM, Evo 8 TB, DeltaCam 272/264 Cams, Test Pipe, OE Avenger V6 60mm catback w/muffler, modified Outlander header, DIY COP setup, B/S delete, 315cc injectors, AEM UEGO WBO2, Black case 3G ECU
1994 GS FYI
DSM/CSM Manuals
What r u talking about? There are no 61/67 turbo heads-these are from mirage 1.8L and thats why they are smaller. The 94 GS Galant has Dual cams that are no different than any other 4g63 non turbo head / n/a 1G 4g63 Eclipse/. Only the turbo 4g63 have agresive profile cam shafts.
67 are only NA, 61 came either NA or Turbo. The heads themselves are the same, NA or Turbo, except for the 61/67 and 2G. The 2G has smaller intake ports than the 1G heads, the 61/67 has smaller combustion chambers but have 1G intake ports. Turbo cams have 252* on both intake and exhaust with the 'C' and 'D' stamped cams have the best profiles. The 94 GS has 260*/264* cams with letter 'G' stamped on them.
1G Turbo/NA Cams
I'll post the 94 GS cam profiles later.
Nevermind, here.

Well those cams came from my GS head before I swap to a 4g67 head. I search a few service manuals and Cam ID for those cams aren't listed. They listed the cams for the GS as "K' and "H" but same duration.

On the 8g's On the shifter it say L,1,2,3,R,P and i want to know can i put that in my 7G
you can install it with some modifications, but itll be only cosmetic mod. youll still be going thru 7g's gear selector.
And what does that have to do with head differences thread?
i was saying it was off from this but who does make come good cams HKS or RPW'S
RPW makes SOHC cams....HKS makes DOHC cams...this is getting annoying

The intake 'C' is most likely from a non-US Mitsu.
