The hi ram is actually fairly short compared to our stock intakes. Believe it or not the runners inside the stock intake are lengthened by bending and twisting inside of the intake, creating a longer runner. The hi ram does better in the higher RPMs, Holley claims 7000-8000. Or you can make it all happier with boost and not have to rev that high.Thanks man, you know I was actually undecided between the ls3 and the high ram intake. Im leaning more towards the high ram but reason I haven't pulled the trigger on it is because i know those intakes with long runners are good for low end torque, with that being said I plan on running a 30 3200 stall and I don't know if they'll still perform good on high rpms. With a stall like that im assuming ill blow past the torque curve where those intakes really make power, or will ill be alright and still make decent power all across the power band?. But yes those two are my options and you did clear out some stuff for me, I think ima go with the holley unless theres a reason not too? Just wanted to get some opinions on what intake I should run. Thanks again for the info man
I totally forgot that the LS3 heads I think have a tighter combustion chamber, can't quite remember. Can anyone confirm? L92 and LY6 have 70cc chambers.
***EDIT*** same size combustion chamber for LS3/L92 heads.
canadianVRss I agree about the holley hi ram love that intake awesome not only does it perform well but looks so good ... as far as ls3 heads with hollow stems yeah the valves are light but have had a few come back with head of the valve snapped off and usually happens when coming into boost. I was lucky enough to titanium out of zr1 for mine cheap ..check corvette forums for them
Good to know. I wasn't aware that was a problem. Sounds like the titanium valves or solid L92 valves would be better for boost.

impressive, well done.

well, I'll throw my two pennies in on this one. LS3/LY6/L92 heads are basically the same. a few slight differences. besides casting numbers...
-LS3 heads have sodium filled valves. it doesn't seem like a big difference until you think about it. the intake valves are rather big on these heads. big = heavy, when you're spinning passed 6000rpm, the sodium filled valves are much easier on the valve train; (that being said, I've spun my LY6 heads to 6700 for the last two years without a hick up, the LS3s should have no problem 7000+). the sodium also helps wick heat away. LS3 heads would be my choice if I could snag some.
DON'T get a LS3 intake. so much work required to make it fit. you'll have to run car accessories, in short its a total PITA.
Now I can tell you that I was in the same boat as you not long ago. Here's what I did. I went with the Holley Hi Ram... now there are many pros and cons and im sure there are folks I could battle with all day about it, but ill lay it out for you. you want to go boost, do you trust a polymer intake under high boost? now you might say I don't plan on going high boost, 8-10lb at most." We all know power is addictive, you'll eventually want to push more air into it. there are many other little things you'll need to change to make it work (fuel line adaption, LS3/9 bolt in style MAP sensor which you'll need anyway for boost and some other things im missing im sure).
this of course is just one option, but it is, what I feel, is the best way to give yourself a little growing room for boost. that being said, the L92 truck intake is a good unit for sure and people have been putting the boost to them as well. I went this route originally, but then ended up going to the Hi Ram for the high boost I plan next year. just trying to give you a few options so that you wont have to leapfrog between intakes (the whole reason for me writing this).
anyway, sorry for the rambling. as for your questions. your stock LQ9 fuel rails wont work, you'll need to hop to the rails that come with the L92/LY6 intake. your existing quick disconnect fuel line fitting will clip onto those fuel rails just fine. as for the LS3 fuel rails, im not sure as I have no experience with them.
for the injectors, go big. if you plan on running gas go for some deka #60s. I've run them in both the L92 and the Hi Ram. they fit perfect in the Hi Ram on the tall setting, but will need some shimming on the L92 intake. if you want to go with ethanol, go #80 or bigger (might need to go bigger depending on your boost level). my reason for suggesting the dekas is because the data for them is readily available. tuning with them is much easier because of this.
your stock LQ9 pigtails are Multec ll type connectors. but adapting to other types isn't really a big problem, so don't let that be a breaking point to disregard a good injector.
best of luck and have fun man!

I don't believe HPTuners supports apple software.

I know, I'm asking why he didnt go 408 since its all apart anyway and the block is preped.
-
Long time. I got a question for ya, why not a 408 over the 370 since you got it all apart anyway. Can't wait to see this one come together.
-
Do you have a shift kit installed?
-
Ahh I see, then rectangle port heads would be the way to go if you are getting a new intake anyway. It'll give you the opportunity to go to a four bolt, 90mm or larger TB as well.
-
The rectangle port heads do out flow the cathedrals. But you can't just budget 1300 for a set of rectangles because you'll have to factor in a new intake manifold as well.

op got his shit tuned.
Indeed

Most tuners just turn that code off, PCM doesn't conduct test to determine if a fault exist btw. So it's really not "fixed". This is why I get upset with many on this board. Don't get me wrong, I'm not saying tuning isn't crucial! But if you don't know anything about tuning for a particular mod, then plz.......
Dude, that's what I'm saying! I know the PCM doesn't conduct tests to check for faults, it's told of faults. Those codes need to be turned off! I don't know about you, but having a CEL on pisses me right off. Having a CEL means something is wrong, even if it is something that just needs to be "turned off."

Nah, just a sunfire 2.2L 5speed stick. I ran it for two years before checking my plugs... It started idling rough, turns out they had no more electrode left haha. Those plugs look pretty bad too.
-
It should last you for awhile if you treat er right. Got mine for 1600, came with extra tires and rims (winter) and remote start. They like to rust though, damn road salt.
-
Mine went 3 months before I retuned it. Never hunted for idle, only shifted a little too early at part throttle and threw the 0757 code every now and then. Sometimes it would lock and unlock at 45mph. All in all not hard to fix if know anything about tuning these trucks.
Not directing this towards you in particular, but I get tired of reading posts for guys talking about tuning, when they have NO IDEA what they are talking about. I mean if some dude across the country does your tune, then plz don't tell people what needs tuning and what doesn't. I actually had a guy on here, tell me that my truck would run worse after a header install with no retune, on a stock truck, I mean WTF. You get a cel, but I assure you, even with the stock tune, you will make more power with LTs.
I just don't understand why you wouldn't tune for such a mod. Our transmissions are rather delicate as is. I understand the whole across the country thing. But some of us travel across the country to chill with our tuners. Basically, if the PCM is throwing codes at you, something needs to be fixed/modified (retuned).
-
Sounds like fun! Bring the sunscreen! Haha
-
97 sunfire for me. My winter and work beater.
-
Why wouldn't you drive it??? Would a tune help in this case? Absolutely! Can he drive it the way it is?? SURE! That's a normal code after a installing a higher stall TC. Going off memory here on that code but I believe it has to do TCC duty cycle.
There are a few things to consider. Even little stuff to me needs to be tuned to dial it in.

Definitely a good time for no cam!
-
Cam (and all supporting mods) a stall and a tune. You'll have no issues

Not a bad 60' there's still some left there though. As for the top end... You need a cam, then you'll be deep in the 13s I'm sure.

Flirt with her, if she flirts back she's obviously interested. Don't wait too long though, or you'll be.... Wait for it... Friend zoned!!! Haha this thread is full of hilarity btw, good read for sure.
-
If you didn't tune for it I wouldn't even drive it.
-
I had to pull my drivers side head. Then punched a hole through the broken bolt right through the head. Be careful because the broken bolt is extremely hard from the hot cool cycles and will require a lot of pressure on the drill. It's easy with all that pressure once you break through the bolt to punch into the head.

Good luck man, I hope to see some good times from that truck of yours!
