I cant find a strait yes or no asnwer. So heres my question. Can you hit 400rwhp with stock turbo cams?
 
Ya with a turbo thats bigger than a 16g. I have 321hp 347tq with a 16g stock cams and a stock side mount so i don't really think it would be that hard.
 
Why would you want to? wouldn't it be easier to just buy some $400 dollar cames and throw them in, they will only help you.
 
Budget build an extra 400 dollars is a lot, then you will need an extra 2-300 in springs.
 
Most 272 cams don't require springs, and some that say they do are fine up to 7-7500 with the stock springs.

We can't really recommend anything without knowing about your setup. At minimum we at least need to know what turbo and fuel you'll be running.

Yes 400hp is easily attainable on stock cams, as well as a whole stock long block, but the more supporting mods you have,the smaller turbo you'll be able to hit 400hp with. It's not hard to break 400hp on a 16g with cams and good fuel.
 
Ok well heres what we know so far, 4G64 block, 4G64 crank, Forged 4G63 rods, Forged Pistons, Eprom ECU with DSM link, Wal 255, unsure on injectores yet, Midly ported head, and for turbo we are running a t3/t4 style somewhere in the .63 trim area.

Considering all this stuff, it doesn't really sound like you're on an ultra-super-tight budget, so why not spring for cams and get the best out of all this good stuff you are putting in?
 
.63 is an area to radius ratio (a/r) for the turbine housing, not a trim calculation for the compressor wheel. Which turbine wheel are you going to use and which compressor wheel are you going to use. The t3/t4 platform with a .63a/r housing ranges from 350whp to 700whp.

272 style cams work decent with a 4g64 stroke. Better than stock cams with a 4g64 stroke . . . that's for sure. You can get regrinds for under $200.
 
I believe the turbo we are looking at said it was a .63 trim or we looked at a .57 trim, both had the .63a/r listed with the trim. Its not a super tight budget but my friend is supposed to be helping buy parts and he has helped with anything yet while Im in a grand already.
 
I also cant afford cams and have decided that I could put that cam money into a larger turbo setup and have a lot more gains than I would if I bought cams. My goal is 550whp on stock cams and intake manifold. You will be fine for your goal.

There is no such thing as .63 trim garrett turbo :). Did you see this on ebay? There is a 57-trim garrett. That is a 42lb/min compressor. About like an evo3 16g. Which turbine wheel? Hopefully it's a t31 (t3 stage3) or bigger. If not, then you'll certainly need cams.

WTF That's quite a goal there. What turbo are you looking to buy?
 
Yes its a ebay turbo, maybe it is that same one you speak of Ill try to track it down.

This might help people understand what you're trying to say.
For everyone that doesn't understand A/R sizes and compressor sizes.

Well we want at least 400whp if not more so give me some suggestions we dont want to buy a thousand dollar turbo though. We just wanna get it running put down some dyno numbers and sell it

So you want to slap a few cheap parts on a car to produce a couple of good dyno runs and then sell that POS to some unsuspecting newb for considerably more money than it's worth.

Sounds like you're one of the reasons this board exists.
 
If that was the case I woudnt be puttin in forged internals. I would run stock internals and not care if it shelled on the next person. I just dont wanna spend 10,000 dollars on this truck and sell it for 5, thats not the plan.
