Yep

That's what I figured. Just wanted to be sure. Day 3 and no leaks or issues. Talked to Bill at Moore over the weekend and he's going to get the tune situation sorted out with Uprev and GTM today and then schedule some time to come in and finish the tune(s)

Yeah oil viscosity is going to change with temp and outside temps can definitely affect oil temp...

Plus as the metals in the engine expand and contract (at different rates because they are different metals) the tiny oil-filled gaps between parts will expand and contract as well.

Does anyone know where the oil pressure sensor is actually located on this car? Is that it hanging off the front of the upper oil pan near the filter? (There's two there, I think, I assume one would be pressure and one would be temp)

:tup:

Yep, one is pressure and one is temp. There was a diagram posted somewhere (will dig it out) which pointed to which is which.

can wait to see those numbers :)

Currently at 450whp / 338 tq.

We'll be throwing on those Motordyne ART pipes before the tune though.

Well if you beat Baer then everyone will be happy. :p

Thanks alott:shakes head:

I don't think anyone with a SC will touch your numbers for a long while.

He has some stuff up against him where he won't get to 500

Those test pipes will kill the TQ and the 92 mm pulley is to big.

I think he will end up with 475-485 HP and 355-365 tq

those are good numbers bro!!! you have stock internals or you forged your engine???

Stock internals (currently). I'm not going to push it above 500 for that reason. I'll see where it ends up once the tune is tweaked but I'm hoping to land at about 475-480whp and 380 tq.

Please do not turn this into a dyno high score thread. That is not what I'm doing here.

That is not the point, it was just to poke Baer.
Your build needs to be a staple for people to follow on being cautious but goal oriented and planning. I see to many builds with people going, I want X horsepower but have no plan or idea what to do.

Man those are great numbers for be in stock internals bro!!! i hope everything runs ok!!! i hope some day install an SC thats the reason of my questions!!!:tup:

This has been a very cautious build. If you are interested in going the SC route, it's worth a read.

Please let me know if you have questions and ill do my best to answer.

Thanks a lot DM!!!:bowrofl: of course when im ready to build my car with a SC setup im going to contact you... for now im working to the exterior and in N/A setup ;)

RE: E-85, what do I need to run it? I was operating under the assumption that it was much more expensive than 93 octane and apparently I was way off.

It's like $3.00 p/g

1) Can I run it without a return system?
2) Assuming the cats are off the car, what are the drawbacks? Why wouldn't I drive around on E-85 all the time?

The cost per gallon many times is cheaper but you have to factor in cost per mile also. E85 burns more so you will lower your MPG and in the end might not really save any money on a daily basis.

The pluses are it can run cooler and provide easier HP compared to pushing 93 or higher octane. I believe for moderate boosted 370z you need the proper injector size and fuel pump to match on this car.

Depending on the size of the injectors you just put in, you may be ok or you may need even bigger ones. Your mileage will suffer, and that will negate any savings from the lower price per gallon. Availability can be an issue. Also, you can't really switch back and forth between 93 and E85, since the little bit of gas left in the tank will throw off the mix.

I have bosch 645cc injectors and uh... A Walbro 255lph fuel pump I think.

Any danger to the car? What are the risks without running a return system?

There's no danger to the car from running E85. The only issue would be if the additional power ended up being too much for the stock motor.

Ok let me rephrase then: What are the benefits of a return system assuming I have an E85 tune on the car?

For a really good answer I'd reach out to Phunk. He seems to be the guy for fuel systems. I stopped researching the fuel return when everything I found made it seem like it was unnecessary under 600whp or so.

Based my fuel system off of his recommendation.


Glad you posted on here Mark. Responding via Facebook mobile on my phone takes forever.lol

645cc is TOO small. Use that fuel calculator I sent you. To run your injectors at a safe duty cycle for 500whp 1000cc is recommended. I know many people will say my statement is false but talk to Phunk he will tell you the same. Everyone thinks my fuel build is overkill size wise but it isn't for E85.

i think you are correct!!!! when i tune my 2005 Sti i use 850cc with meth and 91oct and we reach the 475whp but the injectors are in 95%... my tuner tells me that if i change the injectors for a 1200cc we can run 500whp with any problem!!! so i dont know much about the SC but i think its almost the same that a turbo in that way!

I think I'm going to put this on the list of "stuff I'd like to do eventually but not right now".

Still need to upgrade the clutch and tires before I do *anything* else (and I mean anything).

Yeah, get the setup you've got on there now dialed in before you go hunting for more power.

What about bumping up to GT-R spark plugs? I have seen a lot of folks do that in FI builds. I mean, I can't see WHY it'd make a difference but a lot of people do it so maybe I'm missing something.

Are you on OEM plugs? The GTR plugs are 1 step colder, and a lot cheaper than the HKS plugs GTM recommends. That's about it. They're not really going to add any power. If you're still on the stock plugs, go ahead and switch them out.

:tiphat:

I know I am I just try to be civil on here Thank you though. Im sure the extra confirmation will help prove my point :bowrofl:

Yeah on your sti 1000-1200 will get you to 500whp @ roughly 80% duty cycle which is awesome.



Mark, it is worth it to go to the GTR plugs like Chuck has mentioned. They are 1 step colder.

Unless they came with the SC kit, I'm still on stock plugs.

They don't come with the kit.

I know my friend!!!! you are trying to help with your knowledge and that is what i love in this forum :tup:

Likely the last update for a bit:
-Sam/GTM and Uprev are working to unlock the tune. Sam said it shouldn't be locked but for some reason, the tuner was unable to modify it. They hope to have the issue figured out today.

-Sam also said the tune they gave me was "very conservative" and that there was a lot of room for more power.

-Motordyne ART pipes are somewhere in the air over california right now.

Hoping to get everything squared away the week of 9/2 (labor day).

Odd behavior (and this may just be me not knowing boosted cars):
Pulling hard in 2nd and got a little too close to redline and near peak I had a sudden and almost complete loss of power. Shifted into 3rd and was fine. What gives?
