Civic EG

ok so i am contributing to saving the SOHC and keeping mine. these are my plans.

Intake
Headers
Exhaust
Y8 intake mani swap (i was thinking of upgrading the TB but is there even and upgrade?)

then maybe some minor head work and then boost from there but for now all thats listed above lmk what ya think.

I believe you're better off sticking with your stock TB instead of shelling out cash for one the same size from a different engine.

Last I can recall they are all the same size.

The Y8 Intake mani is Wayyyy Bigger then the Z6 or other Intake Manifolds.

y8:


z6:


Topic on b7 vs z6 Intake Manifolds - The Intake on the Manifolds on the b7 and z6 manifold are the same size, the Runners to the Engine however are bigger on the Z6.

i just finished my build and do a mini-swap with a z6 and use a thin headhasket, u will bump up the compression also use stock IM and throttel body inless u have cash to do skunk or elder , dont go with cheep ebay or other cars as u can even loose HP off un-even balance of air)fuel

also,will ur at it get new rings u can get some for like 30$ will help a lot and wont burn oil anymore !!


and if u want to get crazy like i did then skunk cams and valves and p-polish head and IM and u will be set to go, GOOD LUCK !!

wtf engrish? The y8 manifold has better results with aftermarket mods than a z6 manifold but I don't believe it is worth the trouble unless you dont have a z6 manifold or get it really cheap.


DONT get a thinner headgasket. If you plan to boost, a stock oem headgasket + arp headstuds will be fine. If you want a bigger TB a stock LS will work decently with the y8 manifold and should bolt right in.


skunk2 cam + boost is not exactly good with power. Crower Stage 2 turbo cam + any upgraded valvetrain is good for boost.

I say hold out on the bigger parts, just get the intake header, and exhaust.

ohh hes bosting, i thought NA just swaping in a d16z6, also if on tight budget then stick with the IM u got if not then yes go with the y but its not like the y will add10+ HP then z6 also, looks y kind of stupid, my opinion

yeah thats my main idea for now and once i get more research done then do the Y8 mani swap and other stuff after.
