Stock Vs Boost!!!!!!! What to do?

[PiketC1868]

Ok people this is what im trying to figure out! Im Boosted and running 10 psi pullin around 340 dynoed. I want to push more boost, but im not sure if its safe! People say here and there that the 2AZ-FE is forged already because its designed to take the supercharger off the assembly line! Which makes complete since. Chris Rado has also produced a tC with around 600 HP, using a stock Engine! Now im already saving up for a kit to harden up my engine( very fucking expensive just FYI) here is the link if yall are interested! http://www.ptuning.com/html/search-r...l=tC&Brand=per (http://www.ptuning.com/html/search-result.cfm?cmbCategory=engine&cmbSubCategory=shortb&MakeModel=tC&Brand=per)

I just want to push more boost until then! 14 would be perfect and after the new cams, pistons, and all that jazz comes in i can boost it up to 18!

So if yall have any ideas! I need the info!

The lower rotating assembly will only take so much pressure before giving out. Lightening and polishing the crank plus a good set of rods and hardened pistons you can go to 8k and 20psi (proven) to maybe 40+psi without an issue. It is building the head part first that's the issue. All of the engine work is pretty cheap, I spent maybe 800 in parts and probably going to spend another 300-400 in machine work for the engine. Head work is atleast 600 in parts and another 600 to be machined, that's not including valve work. You don't really need sleeves just a good tune, Rado proved that.

For what you want to do changing the rods and balancing the whole assembly would be plenty. Cams for our car have never been proven to give any performance gain at all. Save for a head job...

Once you remove the balance shafts you will notice a huge difference in how the car feels. The Ptuning kit is nice but you have to send them the block and they charge alot more than it would cost if you did it yourself. We have some of the best machine shops in America here in Texas, they mainly specialize in domestics and diesels but they could do a number to our block for alot cheaper.

Thanks bro that was the 1st ligit info i got so far! i had a feeling that the Ptunning was a lil raw on the price! you have any suggestions on to where to get the hardened internals or a machine shop in tx?

ohh and cause i drive the car do you thik i could pull off the cam and shit off a wrecked low mileage 2aezfe? and get it worked so i can drive it until the work is down or would you want to use the actual from my car?

[masterp627]

PTUNING can be expensive but their stuff is track tested on their 550 hp tC. The guy that tunes my car has their block and turbo kit (with a bigger turbo now) and he is pushing 600hp no problem. If you find a cheaper way to do want you want and you trust the people doing it then go for it!!! I just want your car to break down cause someone screws you over. Good luck on the build bro!!! :D

As far as machine shops in Dallas specifically I don't know any but Fabtech off the top of my head. Good place to start is go to the track and ask people, personal experiences are the best judge of how good a shop is. Don't think a shop is more uber than thou just because they use the same car as you; there are tons of shops out there that are very well versed in machine work and engine building.

Most shops will balance a full rotating assembly. You might want to see about getting your cams polished and replacing the buckets. I plan on getting the Brian Crower valve springs and retainers then getting my head machined (hopefully oversize the valves by a mm while i'm at it), and running the stock cam polished. 90% of how well an engine holds up is due to tune though... If you have a bad tuner you might wanna get a shop like dezod, ptuning, or descendant to do your engine and put sleeves in.

Another good place to start if you have questions is call Dezod up, they have some of the best customer support out there and are very knowledgeable.

Thats a god damn lot of whp for only 10psi.

How exactly did you pull that off?

Was kind of dyno did you get that number off of?

What was your torque number?

Scanned your dyno sheet yet?

I'm very curious because I'm running the Turbonetics kit as well @ 10psi, but I didn't dyno ANYWHERE NEAR that amount of whp.

Yes, my internals of the engine/trans are stock.

I dont just have a turbo man! And if tuned right a stock engine you can squeeze out around 40 to 50 extra Hp out of it!
With headers stronger waste gate springs, and all your other shit if done right you prolly could pull around 340! its got alot to do with the tune and your mods not just the turbo

Thanks good knowledge!
Ill start digging deeper!
Ohh yeah do you know any local tuners mine moved to florida!

[TheFantasticG]

Your tune must be super aggressive then. And I do mean ultra mega super aggressive.

You don't have anything listed other than the exhaust and AEM ECU that would affect the WHP.

What kind of dyno did you get that number on?

What gear do you have it pulled in?

What was your peak torque? At what RPM?

Scan the dyno sheet yet?

I'm interested to see your AFRs.

the prob is i dont have all that info on me!!! Its in the car In the states. SO when i get home! Ill scan and all that Jazz and have it all up just for you! lol But at the moment i have to guess!

Get a good tune. There was a guy in Denver with ~390WHP tC, on 14psi GT3076R turbo. Turbo size is important because 14psi on a smaller turbo is very different than on a bigger turbo. Tuned on the FIC. Also had meth injection. I drove it a while back, and the car pulls HARD. I heard he made some tweaks, and is in the ~410WHP range.

He daily drives it and afaik is still running strong.

I have a T3/T4 hybrid by turbonetics

[TheFantasticG]

Turbonetics T3/T4 50 trim .48 A/R Turbo

Thats what he has now. Same as I do.

I'm very interested to see the dyno sheet. Get it up a.s.a.p.!

That other guy started with a Turbonetics kit also, then upgraded to the GT3076R. That's why he has so much power on 14 pounds. More CFM FTW.

Yeah i was looking at it and it will be a direct swap, So thats wht im going to do!!!

Like the down pipe header and is it water cooled

[pinoyFMtC]

http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT30/GT3076R_700382_12.htm

^That one is.

I think he kept the Turbonetics downpipe/manifold, but I'm not 100% sure.

Find a good tuner also. Essential for making good power.

^This thread highlights the modifications needed to make the turbo fit with the turbonetics kit.

[TheFantasticG]

Turbo's don't have a header by the way. It's an exhaust manifold.

Piket, you do know that the turbo you have now is water cooled right? I can see the water lines in your pictures on your profile.

You should do a leak down/compression test on your cylinders if you haven't already.

I know it manifold i just have a habit saying header. i know its water cooled, but wht is that test 4

[TheFantasticG]

Basically the health of your piston rings ability to seal.

The compression test is a good idea. Not too hard to do either.

Ive never done it! Any info on it?

[TheFantasticG]

Info you are looking for. (http://www.aa1car.com/library/compression.htm)

[pinoyFMtC]

I THINK you pull a spark plug (and maybe the EFI fuse so the rest of the plugs still in don't fire. You don't want any of the plugs firing) and put the compression tester where the plug went. Crank the motor with the throttle open, and there should be a compression reading. Never done this myself, but I heard this is the process.

wont lie boost is an awesome feeling but man being boosted is expensive believe me lol building the engine on mine for the 2nd time within a year of owning it.. already had to replace the throw out bearing as well.
