I finally got my cams in!!!!

I know i was talkingabout getting some cams from darrell cox BUT they were expensive 1300$$ for a set sooooo

i ordered a custom grind from crower

duration is 264 intake / exhaust

gross intake lift is .465

gross exhaust lift is .446

so what do you guys think???? i think there gonna be hard core!!
 
What was wrong with the crower 2 turbo grinds?
 
So when exactly do you plan on breaking world records and all that hehe. I'm really excited for the 420a this summer...it's gonna be a good one :thumb:
 
i was going to go with a 274 duration wit hlift being just under a half inch
but
that cam profile might have been too agressive i remember rading on neons.org that cams with a very high duration at high rpm like to pop off the rockers soooo being that i can not find after market rockers right now im trying to find a company that will make a custom set for me.....

any suggestions
 
Hey man,
Those are some pretty hefty numbers. I wouldn't go for anymore duration that what you are looking at now. If you feel after you have them on that you need more then by all means dial that in on the cam gears. As for the lift, are you shaving the head any? What's the comp again? I'm a little concerned about that much lift (.465) with the high rev that you were talking about doing. Did you check the geometry on that set-up? I'm concerned about the C3's hitting (though I'm going 12.1's with the .020 shave) much less the special grind that you are looking at.

i think he will be fine, i did an all motor build a while back that the customer did not finish but it won the dyno day at NHRA two years back (check website for verification) and after shaving the head 12.5:1 JE's the comp was around the 13.1 to 13.5 range ( all math done by a machine shop and compression gauge read around 280 to 300 on all cylinders after it was done and broke in) it also has crower stage 3's in it and had no problems, one of the cams even broke on the setup and caused the belt to break and barely i mean BARELY bent two valves. just an fyi.
the car made 166whp but nhra put 162 because they dont know how to type or some shit, this was with no tuning and AF's in the low 10s to high high 9s.

Justin, you just saved me a bit of time and concern. Great info! Must have shaved the sheit out of that head to pull comp to the 13's. Approx values of .050 shaved. Though I did shave my 4g63 to .053ish (?) with FP2's and got away with it.

:p Love the AF's :D

yeah he was a cheap ass and we put 310cc injectors in it and only had the very first afc wi the five nobs to tune with and it would not even get clost to pulling enough fuel obviously, he has givin up on it and the head is now part of my car and the cams just sit and do nothing at the shop which are now a crower stage3 intake and stage2 exhaust which he wanted to do for no reason at all after the cam broke, so now he has a 12.5:1 or higher motor for daily driving, it sucks for me cause i put alot of time into the car and all he needed was an safc2 fuel return line and some slicks and the car probably would have went easy low 13s with the weight it was pushing (2580lbs) and could have hit around the 200whp area but and but and but
 
^^^^^^^ Now thats funny^^^^^^^^

anyway
My head is resurfaced but only to make sure the mating surface is nice and smooth ill have to look through all my machine shop paper work to see how much exactly....but i know it isnt that much to make a diffarance.

Darrell cox said that the 274 would be good with my set up but his cams were alot and plus for me to run that much duration i need to do something about the rockers because he said at high rpm they like to pop off...

Crower said that the cams will be fine and i should have enough clearence with my set up also.

I have 8.6:1 comp. JE flat top pistons.
im also using a cometic head gasket and it is pretty thick too so i should get some mor clearance out of that also...maybe another 1mm

I cant wait too see how this motor is going to act!!!!
and
If it dose as good as i would like it too


Ill probley will upgrade the cams, custom rockers, and maybe even a GT42R !!!!! I hope, I would sooo love to run a GT42R.....just more of my dreams though!! This is just a wish not actually going to happen.
 
That cage well hate to tell ya if it's not computer designed is not good in fact it may kill ya, weight reduction gonna cost a lot in fact north of 3 grand with carbon fiber and even then only 300lb you can shave 900lbs off though, hay send me a pm and I'll hook you up with a guy who did.
And I know of a company that will take a grand off if you got 30 grand.
 
People are too funny.

1. They said the same things about Honda's when they started out.....some SFWD Honda's run lower than 9.60 et's and trap over 150mph....which is more that ANY FWD STREET LEGAL ECLIPSE I HAVE SEEN AND READ ABOUT.

2. Different strokes for Different folks no one should be flamed for upgrading a ride that they love no matter how lame it might seem to you.

3. You dont need AWD to be fast in fact if you look at some of the SFWD 60 foot times they are as low as the AWD guys a 1.5 ,6 or 7 60 foot are pretty common. Alot of automotive physics will tell you to achive maximum velocity during extreme accelration 15% wheel spin is acceptable. Chris Rado once said "you know your making power if you can break the tires loose in everyshift"

4.Yes i have spent alot of money and time on this car but who dosent no one said this hobby was going to be cheap. I dont mind it . I love it and im going to break an set new records.!!

5.You will be surprised on how many pro and semi pro import teams run automatic trannies...i know i was once i started doing the reshearch.

if your not going to contribute to this thrend then fine i dont mind hearing all the haters out there that are affraid of the 420a i think its funny....
 
:talon: ####in aeh!!!!! damn right, if no one can appraciate the fact that we can take a n/t motor and kick everyone elses ass with it needs to just drop dead, LOL but enough of that. i know exactly whats going on. everyone keeps asking me and or telling to go witha turbo engine or get a car that had turbo on it, my guess is they dont want to see me succeed. but hey like you said ya need a lot of "green" to do a hobby like this and i aint quittin yet, not till i can officially piss them honda guys off. (just a generalization)........:talon:
 
+1 for the warnings. I recieved a warning on here, perhaps my first week. Oldman told me to stop typing like a child on AIM. I find it great practice for my college papers. DSM-ZERO, you inspired me to turbo my car. I would have rebuilt it N/A but Mark wasn't making large enough numbers to inspire. I am so happy to have, what seems like, my very own pit crew of techies.
 
..........im sure, just waiting until he decides to open the wallet. :)
.

LOL, yeah, I'm a cheap old bastard! But I creaked the wallet open a little recently, just waiting for the vendors to supply parts.

I'm having a little problem with one of my guys supplying the plate for my intake project, so that seems to be going a bit slower :notgood: .

We'll get there :thumb: .

Appreciate the support,

I know of a guy who spent $14,000 on his did all the same stuff you are doing and it has no top end, he says he races in the 200hp class and can get ya out the hole but his top end makes him cry.
And that other guy in Canada I forget his name has no bottom end.
So don't get ya hopes up too high that it's gonna be perfect you are gonna lose one or the other.
 
I've deleted some posts and don't want to have to babysit this thread. Let's keep it on topic.
 
i called the shop and they ordered a Moroso oil pan for a neon, They said that they can make it work....

but
my question why wont it fit on the 420a eclipse
 
In reference to the Moroso oil pan:

Well sort of. You see the oil pan was designed for the Neon. Now as you know the Neon has the exhaust in the rear of the motor. Keep that in your mind set for a minute.

Now look at our oil pan and see how the left side of the pan is notched? As you know in that notched area is the Downpipe and our center member. So now you see why it wont work.

The oil pan will bolt up but when you go to set the motor in the car is when your going to find the problem. Even if you dropped the downpipe below the oil pan, the centermember would still be in the way.
