correct

thats why i said 250

an oem pump from a 6th gen can usually dish out 400whp for a while

250 is a little close to the edge, but still usable

BTW, I forgot to say, great number on an a6, it has low compression

Throw a d16y7 head on there to keep it nonvtec, but enjoy more flow, and more compression for more VTAKZZ KILLA POWAHZZZZ

 

I tried that. It didn't work. The ports on the Y7 head don't flow worth beans, and the OEM cam is even worse. I was seeing 25psi of boost with my Endyn M62 blower setup using the Y7 OEM head/cam. The boost couldn't get into the combustion chamber, and was backing up in the manifold. I'm on a Z6 head now with the Crower turbo cam, and the boost is down to 22 psi.

If you're set on non-Vtec, get a Y8 head and a Y7 head, and make a baby. Use the Y8 head casting, cam caps and valves/springs, etc..., but the Y7 rocker arms, rockers and some sort of reground Y7 cam with more lift and duration, and make a non-Vtec hybrid that'll flow decent.

 

I understand teh y8/y7 hybrid
I thought you were still on the A6 ehad, so from that, a Y7 would have been better.

Course, head porting would take care of the pressure problem

 

Ya i have a y8 head to put on it. Were Hoping with with a new pump and y8 head we can make over 200 whp on the stock motor.

 

200whp sounds feasiable, but since you did this with a Z6 head, dont expect too much more.

the z6 (in stock form) has the best flowing D head.

Should be able to make more power earlier with the Y8 head, but your peak might only increase a small amount. The extra compression would have been nice, but it heats the combustion a tad more lol

Have you considered fabricating an idler setup, and making a water-to-air intercooler that bolts between the SC and the manifold adapter?

With the added cooling, some SC guys can hit 15+ more hp, but clearances in teh engine bay are of course even tighter

 

something like this but in a thinner, flatter scale

 

you must have me confused with someone else, i have a stock d16a6 making this 178whp and i plan on putting a y8 head on it.

My plans are really this: But the 255 walbro in cause i have one laying around, put the y8 head on with arp head studs and cometic head gasket, get it retuned and hopefully make 200whp. Then daily drive it.

i just wanted something fun for this year .

 

my bad, lil confused lol

178 on a full a6 s an easy transition to 200 with the help of a y8

y7 valvetrain if you dont want vtec wiring or the need to do cam profiles tuning

 

alright cool thanks

 

hey when i mate a y8 head to a a6 block i use the y8 head gasket right ?

 

all 88-00 d15 and d16 headgaskets work

'thickness is what is different

z6 and y8 headgaskets are the thinnest, and produce the higehst compression

if you need lower comp, a d15b7 headgasket fits the bill.

considering we are talking only a few decimals of compression difference, go for the metal ehadgasket for a d16y8

find it on ebay

 

If anyone has a JRSC kit up for sale, hit me up on here via PM. Looking to get one ASAP. Thanks.

 

Just installed the y8 head on my a6 block. before the head swap i made 179 whp and 160ft/lbs

looking to hit the 200 mark maybe a lil more would be nice

 

what other mods to the engine?

 

Before
This is when it was a stock d16a6

Hpr Header with a stainless 2.5" exhaust
jrsc 9lbs crank pulley
short ram intake
aem fuel rail
Fic 550 injectors
converted to obd1

I made 179whp and 160ft/lbs on e85.
Around 5k the stock fuel pump started to get weak.

Now:
I installed a 255 walbro and y8 head

They say the y8 head flows alot better and i had it laying around

Hoping to get it tuned this week and break 200whp mark

This is my daily also lol

 

Broke the 200 mark with ease

Got a 97 civic ex couple weeks ago, really looking into all possibilities for it. It's mostly stock - a brand new canvas :-)

What do you guys think about a sc in it? I'm trying to plan for the long run so I don't make the mistake of buying a bunch of crap only to engine swap or turbo or sc it later.
For quick reference the 97 ex has a d16y8 engine.

 

If you are thinking long term, go turbo. Long term to me= 5+ years

 

where can I pick up an upgraded boost pulley. looking for the 3.2 or 3.4 the standard one is 3.6 correct?

 

What I meant was I want to plan long term as in save most money for now and go with the best decision for most power.

ex: Save for a year and swap in a b series....or save up and get a turbo or sc.

OR should I keep it na and start slowly working on it with intake/exhaust etc. and work from there?

I've never owned a car for 5 years lol always sell before then.
I love this EX though...this will be my exception ;-)

 

turbo/supercharger will beat any b series, and a turbo setup can cost $800 and beat any b series setup with a full NA build

 

anyone? were can i pick up a higher boost pulley??

 

have one made

its cheap, probably cost $50

They only need to match the center where it mounts, and teh belt stlye

Doing this, I highly recommend using a bigger tensioner pulley to offset the higher risk of belt slippage

more tension MIGHT cause minor acceleration of belt wear, but it will stay boosting rather then slipping

A bigger crank pulley, well you should look into B series crank pulleys. Look up whetehr an N1 pulley works (Civic Type R with B16B 185hp motor)

 

Realize you CAN just find a bigger crank pulley that fits your belt type, say off a factory supercharged car, and you can amchine your crank to accept it

VERY risky since hodnas are internally balanced, rather then pulley/flywheel balanced

ITs a shame hodnas have such a limited supercharger field. Its the only non turbo way to get lots of useable power!

 

Stock blower pulley is 3.8".
