Recipe for 8500RPMs reliably?

[Daedalus]

Some of you know that i'm building an NA motor. Once you stop laughing and wanting to hurt me with bodily harm please help me answer this question.

I want to be able to rev the engine out to around 8500rpm on a consistant basis. The 1G N/T ecu doesnt have a rev limiter so electronically w/e-manage it wont be a problem.

However, i'm building up a ported and polished head for the new engine and need advice on some of the components.

Purchased:
- Mildly ported/polished turbo head
- HKS 264 Intake Cam
- Stock Exhaust Cam
- 1MM O.S. S.S. Ferra Valves
- Bronze Guides

What I want advice on is the best spring/retainer combo for this setup. I was leaning towards the crower springs and retainers from slowboyracing. I'm told that they should withstand that rpm level.

Is there anything that i'm missing here, or will the engine just go booooom anyway?

Thanks for your help.

You would be fine with crower springs and retainers. They can take 9k all day long. If your planning on a 2.4 with that compression, then i would at least upgrade cams as that 264 might have some trouble up that high with such a high displacement motor. Oh BTW, this is 2g copmagnet from OR and i have a set of crower springs and retainers that i just bought from slowboy 2 weeks ago...They are still in the box....PM me and well talk.

btw, a non turbo motor wont need anything more then a 264 cam because he will not flow near as much air as a turbo car, it wont HURT it necessarily but i think hes better off with 264s

Our all motor car runs a 300deg cam with almost .500 lift. Cams on a non-turbo car are critical and using ####y turbo cams are not gonna cut it. If you want power, your going to have to go WAY above what a turbo car runs. You need compression (and lots of it) and bit lift with lots of duration. Turbo cams have high lift but short duration which is not good for an all motor car. A 264 cam is WAYYYY to small for a non-turbo car, remember a turbo car has positive manifold pressure which is why we have hi lift but short duration. On an all motor car you need lift and lots of duration. Overlap pumpin...

If your serious get web to custom grind you some cams based on your compression and displacement. You will likely end up in the 288 range with a .450 lift or so. Make sure you have some valve springs to go along with that...

I wouldnt bother with a non turbo engine trying to make power it just doesnt make sense.
Your NT is made for gas mileage not HP. If you want to make power the easy way just sell it an buy a car that already has a turbo in it. LOT less headakes and will be more reliable. You can pic a nice clean stock AWD 90-93 for about 4k with under 100k on it.

hmmmm i have seen the light
thanks for clearing that up

wow you answered his question to a T... i remember him asking whether he should sell his car and get a turbo or go all motor

you guys need to seriously stop that BS, its incredibly old and we know our options... and again that was only to those few turbo guys who do it... the rest are great help

 

[TSIfreek]

You will see some day.

 

[GSGoinFast]

You will see some day.

im not going all motor cuz i want more power, but we dont need the turbo guys telling us to sell our car... we dont go around saying "why even bother with that GSX, its pointless, just buy a ferrari". just stop alright, its old and redundant, so just stop.

You will see some day.

Sell it!!! you will get crankwalk!!!111one

 

[GSGoinFast]

Sell it!!! you will get crankwalk!!!111one

its a 6 bolt

haha :laugh:

you know how they put number signs for words like #### and shit , well they should do that for every time the words "sell your car" and "buy a turbo car" are both in a post

 

[Daedalus]

The first engine actually did crankwalk for your information. A 6-Bolt N/T 4G63 w/exactly 80,002 miles on it.

 

[Daedalus]

I also would like to point out how much I appreciate you moving this topic to the non-turbo forums where you can be sure no one that is able to answer my question and help me will ever be to read any threads (no offnese to the NA guys, but i wanted some guys who actually have experience on a 4g63 reving that high (streetleeper, you dont qualify).

A 4G63 is a 4G63, and my question would pertain to any 4G63 looking to upgrade their valve train. I dont see why you needed to kick this back in the nonturbo forum where it will never be read again.

I guess I will just have to make a thread and lie about my car and say I have a turbo awd so I can get some help around these forums. :thumbdown

alright...

i has a 2g nt for 2 years...it was my first car, and i got it to run a 15.6 which i was very pleased with due to the slowness of the non turbo eclipses...

so i came to my senses one day and i sold my 2gnt for $6700...and bought a 1g awd with LESS miles on it...and it was $3750...i owed $3000 on my 2gnt, so when i sold it for $6700 i had enough money to pay off my 2gnt and pay off my new 1g awd...

so really i got a faster car with much more potential and didnt have a car payment anymore...it was really the best of both worlds..

i really dont see myself ever getting a non turbo eclipse again...or a non turbo car that is...maybe an integra GSR...but my next car will prob be an STi or and SRT-4...boost is the most addicting thing ever...

and the relevance is???

 

[miamieclipse]

Yea i don't see your point either,

Oh and i have owned my friends gsr if that means anything to you. Yes i do agree with you, i will keep my 2gnt and use my next sti/evo/rx-7 (when it comes back) as a daily driver/parts runner :laugh:

good point... ill be doing that too when mines a 10 second monster thats torn apart for some odd project!

 

[Daenon]

All I got to say is everybody should embrace people who are trying new things no matter how difficult it is. I just wouldn't get into a project like a fast N/T eclipse unless you got some good funds I hope you go all the way and keep us informed.

 

[4g63awdtalon]

with just a boost controller a 1g will be faster then 90% of you.....silly non turbos trying to be like hondas....i mean you have a great platform in a turbo motor use it we dont care

 

[Daedalus]

i'm not trying to be in that 90%. I'm shooting to be in the 10% that no one on these forums knows anything about and is to ignorant to try and help.

If anyone wanted to add anything half way relevant to my question I would greatly appreciate it.

once again, we have another view block here. your heads too far up your a$$ to see we are happy with are cars and couldnt care less that you have a turbo, we have different goals, and we are going to try to achieve them... soo, pull that head out and try and help us, not put us down

 

[eclipse13]

I dont know enough about engines to know about what you need to do to make it rev that high without breaking it, but I just wanna say that i think anyone who completely commits to going all motor and doesnt back out gets my respect. Like daenon said, we should encourage people doing new things instead of being like TSIfreek, thinking that you accomlish something by doing what every other person with a turbo has done. (no offense to any turbo people, there is nothing wrong with using a tried and true method of something)

 

[Defiant]

I'm not going to bother editing this shitstorm.

When you guys -ALL you guys- can figure out how to stay on a topic and not degenerate into the usual N/T-Turbo backbiting, I'll let it run as long as it's helpful.

Closed.
