As someone who is pulling and building a motor himself and making his whole custom twin turbo kit, I actually know what labor is about. Oh and the widebody kit... Don't tell me to go re-search sh*t. Besides that, if someone blindly just does what another person says without researching it themselves then they very much deserve the worst that could happen. That's called being a lazy, ignorant f*ck.

Cams aren't easy but its a lot simpler than building a block, no machine work, just lots of time. Is it worth it? That's up to each owner. Binder brings up a good counter argument. If you raise your rpm limit/make more power further out, you can extend your gears and it should have similar effect as getting a bigger fd ratio without hurting mpg and actually extending your top speed... It's not a bad idea, although like I said earlier I am personally building my motor long before I touch the heads.
edit:
furthermore you could in theory make more hp, because out there there is naturally less torque which is usually what rapes rods... but that's just theory.
I'm just trying to provide another alternative to the cookie cutter response "BUILD IT". You could always go to town on lightening up the car too... I think if I had a greddy tt or other out of the box tt kit, I'd stick with stock block and just maximize the efficiency to keep things as well rounded/reliable/dd as possible.

 

Dude, car looks very sharp. Glad you're enjoying it!

 

Thanks man, were you able to sell yours alright?

 

6 psi must feel slow as ***!! those turbos start to breath at 8-9 psi :-P turn those puppies up.

 

Thanks for the kind words everyone. I do have some questions now though... feel free to throw in your opinion.
I started overboosting a few weeks ago before I went out of town. Nothing too major, instead of peaking at 6.1lbs I am now peaking at 7.1lbs. What could cause this?
I have an HKS EVC VI, everything is hooked up except for the line for the actuator so I am still running off of the springs alone. I have been wanting to up the boost some(~8lbs or so) just to see if I can get the same power with less timing. Basically I am planning to recirculate my open dumps(see below), increase the boost and then retune.
Next, I dont like my open dumps much. It was cool at first but now its just annoying to me. It would be one thing if I was putting down crazy power and was loud but now I am just loud without a ton of power to back it up. Anyways, I plan to have my current dump pipes extended and tied right back into the downpipes close to where they meet the mid pipes. Anything wrong with this idea? How much can I expect to see my EGTs increase?

Once again, any opinions(good or bad) are welcome, have at me FI gurus.

 

so are you just peaking at 7.1 and then dropping back down or is the boost creeping up to 7.1 as you rev higher?

If 1st scenario, that pretty normal for a non-controlled setup. my 1 bar springs would jump to 16psi and then drop back to spring pressure. Turn on the boost controller and boost spike will go away.

as for the recirc dumps, thats perfect way to do it. EGTs wont change

 

Unfortunately I cant tell if it drops back down or not, the biggest drawback to a digital gauge because the numbers move too fast. I'll get the proper data cable adapter this week then log my boost, that'll tell us exactly what it is doing. Either way I'll hook up my EBC, its long overdue. Thanks for the reply man!

 

is that so? why don't you research what happens when people install aggressive cams without supporting mods to to the valvetrain... also watch your mouth.

 

Not to go to far off topic, but I installed the bc2 cams in my car. Its stock block and valvetrain. I full plan to upgrade the valvetrain when I build the motor, I just wanted to see how the motor would react. The install is not hard, its just time consuming...

I do agree tho if you were going to pay to have it done, that there are better things to spend your money on, but they are not useless stock block and valvetrain.

 

I wouldn't worry until you log it.

If it's only going up to 7.1 then it's not a big issue. If it was jumping super high then i would say you might have a problem with your boost reference line (vac line from turbo to wastegate). Personally i would probably check those just in case but i doubt you have an issue since it's only a 1psi jump. Usually if you burn a hole through one of those it will jump up really high in psi until it hits your set level of boost cut programmed in the ecu.

Also, as str8dum said, recirculating won't change egt's. Gas will only get cooler after it passes through the turbos, not hotter. EGT's are kind of pointless anyways. It was a crude measurement people used to make sure they weren't too lean or rich. Now we have nice accurate widebands.

 

I am staying well within myself on here. So I take my sh*t talking to pms to keep the thread clean.

With cams you need valve springs, that's kind of a given. To call me out on not specifying that is pretty...



+1 on egt no changes. There really isn't much reason for egts to spike if your exhaust can flow the air. Also most wastegate recirc systems are designed to be about a foot/foot and a half downstream of the turbo to keep from interfering with flow. That's far enough downstream that it really won't hurt anything important either, unless your o2 sensor is there obviously.

 

bingo.

 

You realize that cam manufacturers (like jwt), TELL you that you need valve springs or retainers WHEN you need them per the cam (not all of them have enough duration to require stronger springs)? So even if it was never brought up, Ginger would have found out either way.


In for logs.

thank you GG

 

Data cable is in the mail, hopefully will have logs early next week.
However driving it today it wasnt overboosting at all. Regardless I am still going to recirculate my open dumps and get it retuned as soon as I know how much my water bill will be...(Had a leak while out of town, used 63,000 gallons when I normally only use 3,000 or less..fml)

 

Congrats on the setup. Jamez and I got our cars done at almost the exact same time. Our setups were almost identical too. I made slightly more power (405whp). Made for some fun runs between the 2 of us at the first Zdayz Airstrip event. I have vids somewhere of the runs.

 

Thanks man, how many lbs of boost are/were you running?

 

Car looks good .. Plus powa
You were lucky to find James... He is one of the nicest and most honest people I have met on here....that's why things went well.

I am sure it will happen sooner than later... You will want more powa... Take Hals advise...

Enjoy...

 

Wastegate was 6 psi 360whp.
With EVC on was 8.5 psi 405whp. DD numbers for both.

 

Picked up this shift **** today... beats my old leather Nismo shift ****.

 

Nice!! I've been trying to resist the temptation of one of those myself.

How does it feel??
