Y7 Cam setup ?

[Belette]

Someone here knows if I get 270 delta regrind cam and my setup is:

Y7 engine:

- Y8 head gasket
- .040 head mill (not decked block)
- Y8 I/CAI/H/E/FPR
- STOCK valves springs (engine internal too) & stock rev limit
Does this cam will make hit valves on pistons ?
It will surely need a adjustable cam gear ? (head mill & gasket)

Applications: Street, 'hard day driving', sometime to race & drag track

or 260 delta cam will be better for this setup ?

Sorry But I didn't found complete informations on searching fields...


Thank you !

Don't waste your time with the Y8 headgasket or the Y8 FPR, they are the same for the Y7.

[S Q A D]

yea youd be better off getting an aftermarket FPR .. like from B&M ...

[Belette]

I got only Y8 intake manifold

stock y7 injector, fuel rail
already have B&M FPR with gage ! I know they are same for y8 y7

Y8 gasket is not a lot thiner than y8 head gasket ?
I read a lot on that and is the thinest stock gasket of D-series...

[bigmrg]

260 mis fine for daily drivers as is the 272 which is what i will be getting but with the 272 you may get a rough idle and you will fine the power band has moved higher up the rev range

[Honda4VW]

I don't believe the Y8 headgasket is any thinner than the Y7, but I guess its possible. I don't really have any data to back that up.

however, I did get these part numbers from SLHonda.com, when selecting the correct models for the D16y7 and D16y8 engines. They do come up the same.

12251-P2J-004 Honda civic 4dr LX $23.54 (D16y7)
12251-P2J-004 Honda civic 4dr EX $23.54 (D16y8)

Did you try each one ?

For 260 do you notice good gain and good torque ? Can I feel it more lower torque and power up to redline than stock one ? Surely much more with some bolt on mod ?

For 272 do you really loose lower band ? Higher is noticeable with some mod ?


thanx

The Y8 and Z6 have the same thickness head gasket.
But finally I really don't know if y7 or y8 are the same or differents, Thing that I know is y8 & Z6 are thinnest D-Series headgasket ...

D15B7 - D16A6 are .048 thick
D16Y8 - D16Z6 are .037 thick

But y7 ?

If you find more info on it let me know !!


thanx

[Belette]

Finally, we go away from my topic,

Does my setup make valves hit on pistons ?


thank you

[kommon_sense]

what pistons? Considering how much you milled the head, you may have to clay it to find out.

[Belette]

stock y7 bottom end !

I know that delta cam have .340 lift

[DOG]

I would switch to the y8 injectors. y7 injectors flow 180 and y8's flow 235.

[pearl62]

My Y7 is running a Y8 head gasket, Delta 272 and 0.020" milled and it does not hit the piston. 0.040" will not hit the piston either. You should always use clay to be sure anyway, just in case more actually got milled...

What!!!???!!!
Where did you get this tidbit of information?

[98DXSLPR]

ok, i just recently had islandercrx install a y8 IM (from infinatenexus), and a delta cam 260 with an aem cam gear into my y7. i can feel the power after 3000rpm but havent really pushed it since i got a CEL code 45. the car idles like stock plus my car is an auto. i havent changed any of the ignition timing or cam timing yet but i'll let you know how it goes after i play with the timing and solve the CEL code 45 problem. the 260 is a driveable street cam but if you plan on going to the track and don't mind a rough idle then get the 272.

Maybe, But I put y8 injectors into Y8 manifold swap and got a lot of trouble like Check engine code too rich or too lean (surely too rich) ,poor gaz mileage, little bit over heating, and no power and big hesitation under 5500 rpm, very black smoke behind from idle to redline ...

I put y7 back with a little custom made seal for hole into injectors seat in manifold for no leak (for I don't know why but injectors have differents tips y7 vs y8) Check engine light turned off, no black smoke and good gaz milleage, much power (a little less at higher rpm, but gained a lot of low end power)

I think that y7 injectors with FPR do a better job with more some psi than y8 injectors alone...

What was your CEL code 45 ? How did you correct this situation ?
I plan to go sometimes at dragstrip or tracks... Do you think that better valves springs is needed if I keep my stock redline ? 272 got bigger lift and longer duration than stock...

The CEL 45 states that "I am running too lean or too rich malfunction on the fuel monitoring system". maybe if all else fails i'll try and switch the injectors like you did. as for the 272, i think that you can use the stock valvetrain. if you are going all motor, why not also switch your pistons to pm6 (d16a6) for some added horses and higher compression.

Interesting information, but im going to have to go ahead and disagree at this point in time. Ill have to research it more, I have a set of both here, and the funny thing is, when I put my Y8 on my Y7, nothing changed

[S Q A D]

i dont know if this is the same , but i just swicthed my manifold over to y8 ... and i still used the y7 injectors ... no problems .. only problem was ... my sensor hookups for my t/b didnt REACH !!

Why I got problems with y8 injectors and no with y7 ?

[98DXSLPR]

ok, here is a little update on the CEL 45 problem. i cleaned my O2 sensor and erset the ecu but light came back on. i checked my ignition timing and reset the ecu, CEL light came back on. Tomorrow i'll be swapping back the Y7 injectors and i'll let you know how that goes.

in regards to the cams, exospeed has theirs out for the Y7's and they dont seem that bad. They have a 262 as opposed to the delta 260, and a 274 as opposed to the delta 272. price right now is at a special of 140.00 shipped (200.00 regular price) but i think you have to send a core. i have heard that the y8 274 by exospeed doesnt have any idle problems, hopefully the same can be said for the Y7 274 grind. is anyone planning on getting one?

[spin_doctor]

I'm definately considering it, but I'm trying to find out what extra's I'm going to need at the same time...

I reckon I'll need an FPR at least but will it be OK without new valve springs?

I run a D16Y7 with CAI, D15 exhaust manifold and a 2" custom exhaust, uprated plugs and that's pretty much it.

I've also been desperately trying to find a Y8 intake manifold and a 60mm throttle body to match but I'm having no luck whatsoever. The UK sucks for parts... :evil:



(Sorry, but why won't my signature work?)

[kommon_sense]

I would switch to the y8 injectors. y7 injectors flow 180 and y8's flow 235.

99.9% positive that all 96-00 civic injectors are 240cc. 99.9% positive that all 1.6L 92-95 civic injectors are 240cc as well. Not sure about the 92-95 1.5L injectors.

i have heard the same thing also about the injectors being the same size, but some guys here have maintained thier Y7 injectors after they did a Y8 mani swap and they don't have any problems. i trying to trouble shoot this one piece at a time. if i switch back to the Y7 injectors and the CEL 45 goes away then problem solved and other people can learn from it also. If it doesn't work , then i'll just get a fuel pressure regulator and see what that does. peace.

[DOG]

Not trying to argue for the sake of argueing. I respect yall's opinions, but I believe I a correct in stating that the y7 OBD2 inj. are 180cc (+/- 10cc). I have seen accels inj chart and I think Holley has a chart stating the oem stock inj. flowing 180. The 92-95 dx and ex do flow the same. However, the 96-00 ex and dx dont. Now, maybe I am wrong an if I am I will admit it .
Look at the big difference in intake manifold design between the y7 vs. y8,z6,and b7. The TB on the y7 is closer to the flange. There is almost no plenum, and what plenum that is there is basically just meeting spot for the runners. Whereas the other IM's have larger runners and actual plenums. I would like to know for sure. Maybe we can find out for sure.

[Belette]

Well, does anyone try Delta 260 regrind cam here ?

I want some comments on it, how much it lift too.


I want to know y7 OEM cam spec, It will help me in my way of choosing

thanx

:)

[kommon_sense]

best bet would probably be to call delta.

[98DXSLPR]

i have the delta 260 in my car right now and it pulls pretty good after 3000rpm. i forgot what the lift duration is. i also have the y8 manifold in my y7. i haven't really opened up the engine to test the cam, nor have i adjusted the cam gear to get some more hp out of the cam till i solve the CEL 45 problem. islandercrx has been trouble shooting my car, and we will be changing the injectors to the y7's today. maybe that might solve the problem. i just thought that with the cam and y8 manifold, that the y8 injectors would be more useful than the y7's, even if they might be the same. if this fails, then i'm gonna get a fpr on ebay.

I you surelly didn't need to change valves spring with that ?
How much cost 260 regrind?
Why you do not purchase 272 ?
When you you will do more test, and if you find back how many that cam lift, let me know :)


thanx

[pearl62]

On the question of the injector sizes... I have recently installed an AEM EMS, and according to AEM there are 2 choices for injectors for 92-00: EX/Si = 240cc (23lb) and LX/DX/HX = 190cc (18lb). My DX would not run right if the 240cc size was chosen...

I don't know if this helps any (ie. how reliable the AEM info is).

Get the 272... it pulls great.. and has a nice lumpy idle

[98DXSLPR]

i think that the 260 has a 257 lift. i bought it for 100.00 from bobbo on the Super Honda board. i didn't get the 272 because the 260 was what was being offered. I am running the 260 on stock spring, at least that is what delta recommended. if someone gts a 272 and can dispell the idle problems, please let us know. i would like more power. the 260 is great for a daily driver and like i said "it idles like stock".

delta 260 with 275 lift
delta 272 with 340 lift
exospeed 262 with 360 lift
exospeed 274 with 396 lift

Holly Shit ! Delta cam don't lift to be compared to exospeed !

I don't really care about idle, If it don't stall, It would be great...

Someone know how much that exospeed sell those regrind and how more power can I gain with Exospeed ?

I surelly upgrade valves spring , I think it'll be needed about any cam upgrade that it'll be made...

[98DXSLPR]

i could be wrong on the delta 260 lift, so if i am, someone please correct me. the exospeed cams a fairly new, so you will have to check on them in terms of idle, but i have read some posts were exospeed said someting to the effect that if it's a daily driver then get the 262, but hey, anything is possible. they are advertising for a limited time for their regrinds 140.00, but now i'm not sure if that is shipped or not. the regualr price is 200.00.

[spin_doctor]

After a fair bit of research and bugging the hell outta Wil :wink:, I've decided to go with a 262deg/.360" Exospeed cam...

I'll be getting it early next month (earlier if I can sell my ICE sooner) and once I've fitted it I'll let you all know what I think of it. I've just had a dyno plot too so I'll post up the before and after graphs to show the real differences.

[DOG]

I talked to Wil yesterday. He said the oem valvetrain should be good with the 274/396 cam as long as you dont push it past about 7000-7500 rpm. Sending mine out today as soon as I pull it out of the head. The 264 doesnt sound too shabby either. Im stoked.

[98DXSLPR]

did Wil say anything about idle problems with the 274?

[DOG]

As far as idle goes, Im not too worried right now about it. He said it will have a slight lump, but I dont know if that will be a problem with carbs, which is what I might use. I think the cam will be good with the dual carbs. Might even like a holley better

[Belette]

Between Exospeed 264 with .360lift and Delta 272 with .340lift

Which one will be the best to keep my stock valves spring and keep power band under 6900 ? If I can stay too with OEM cam gear it will be fine...


Then, which one is the cheaper too ?
