5.0 Killa

Ok is this swap worth it? I can get a y8 manifold for cheap but ive searched everywhere and cant find any details on doing this swap on a z6. Is there anything specific to look out for? As well does that manifold flow a lot better then the z6 manifold?

Anyone?

theres so many threads about z6/y8 interchangability!!!!! i think everythign fits!!!!, just put it on... i have a ****** y8 intake on my 93 cx lol

p.s.- i doubt you kill 5.0's with a z6

i personally wouldnt do it unless something was wrong with the manifold imo..

what kind of gains are you looking at for something like this?

sohcvtec66

i can take 5.0's every day with a build z6

ive talked to a couple of guys and just a y8 mani. wouldnt do really anything for you. if you gat a larger tb, port matched them, throttle response is a bit better and flows better at 5-6k and above, but where the y8 mani. shines is on forced induction. as far as putting it on it should all bolt up the same and work, just be sure you have one out of a manual. thats what i know, good luck.

Thats guys for the actual advice. Tts for a built boosted motor. I still cant find any of these threads on z6/y8 Interchangeability though:p Even If the gains are like 5hp up top its worth it for what im paying for it.

Does anyone know of anyone extrude honing these manifolds?

Get the Edelbrock Performer X! part # 4754, better than both the Z6 and Y8 manifolds.

About $320, hit up Wil at exospeed.

Just a suggestion, you are on honda-tech and repestent us all... your screenname/handle 5.0 killa is a bit ignorant. Esp seems as your trying to gain 2-3hp from a intake manifold swap.

just a suggestion, something a little more personal and civil

man forget that...most Domestic owners slam on us anyways...drive by with a Honda and you get that "stare." Who cares what his name is...should be DCK! Domestic Car KiLLahs...lol j/m.

Just leave with this...people pay up to 100 bucks for 1 hp...if you can get "2-3" hp for less? Go for it

Go turbo, it costs less than that.

A $3250 emissions legal turbo kit ads 70 whp. Only $46 per horsepower.

dew mota, just because the guys trying to gain horses from a single cam it doesn't mean u have the rite to diss on him man. what if he DOES kill 5.0s? just because you dont like it, it doesn't mean you have to start flaming, i usually dont talk back to anyone or anything but you just straight out crossed the line.. YOU are arrogant, and its spelled "REPRESENT." that is ignorant for you.

Umm like I posted before my car is already boosted.

Does anyone have any actual numbers on how much more the y8 manifold flows then the z6?

Also I've never had any mustang guys mention anything about my name, strainge that a bunch of fellow civic guys would...

they are probably just mad that it doesn't say jdm_5.0_killa

Flow has nothing to do with the way a intake manifold performs. Some think so, but flow number will only show whether its a bottleneck or not. There are so many things that influence manifold design and at what rpm range it works well at. In general, runner length primarily influences the rpm operating range and the runner area is influenced by the camshaft profile and the engine bore & stroke combination.

Sonicly tunning the intake manifold is more important that flow numbers. If it was just flow, then a huge 3" tube would run better, but we all know it doesn't.

The main difference between the Z6 and the Y8 manifolds are the plenum design, with the Y8 manifold having more plenum volume with the extra hump on it.

only problem i could see u having is re hooking up your throttle cable. i did a y8 engine swap into a 92 honda civic sedan. on my y8 i used a ported intake mani, and LS throttle body off of a 91 integra GS. my cable still doesn't fit right, but i finaly got it to work correctly ussing an ols LS throttle cable bracket, and using only one bolt. the y8 bracket mounts are back father than the z6 so u might need to make a custom bracket.

This is true. However when under pressure the "sonic tuning" as you called it doesnt matter near as much.
