Can't wait to see the new setup.

how long were you making rediculous power at 17psi with 9.8:1 compression?

there is a certain pressure at which 93 octane gasoline starts to ignite on its own... and at 9.0:1 that's about 18, maybe 19psi.

and what are you using the tune it? (AEM?) what kind of timing are you running?

i'm not trying to hate on you here, just trying to help, as i see you've gone through several engines.
if you want to go over 15psi on 93 octane with 9.8:1 compression you need to run race gas (at least 110) or e85.

my car ran great till I started hitting 24 lbs.

and I have only replaced on block on my car because of the 12v mod and my engine kept locking whenever I turn the ign switch on the on position.

I am running aem, I really wanna get into it that much lol

alpha is one of the best tuner and he tuned lexforlife s car, and I had done my homework there is no turning back for me.

and I have a new setup same engine ...... I don't wanna say to much till its done

I am really trying to brush you off or anything thanks for the heads up.

i'm not telling you to "turn back."
i'm just recommending you "turn the boost down unless you're running racegas or e85."

yeah hes got it under control, he went through many different head setups as a matter of choice not because they blew or anything like that. Omar likes to keep it fresh.
only that particular setup got a BHG because the boost controller decided to not work, and after a check of the logs it was hitting 24psi which is clearly way too much.
It still pulled pretty strong though, there was no breakup or anything at all.

what is the ignition timing like? (again, just curious. not hating)

why dont most NA-T guys buy a new intake manifold? is it because you have to relocate everything or what?

just wondering... i have never done a na-t 2jz and always wonder why people dont buy the greddy for like $1000 more and make their engine bay look gorgeous haha if i would've bought a sc300 i definitely would've went na-t. awesome build none the less!!!!!

Its fine for 19lbs on 93 pump gas, timing was around 15 i am not 100% sure so don't quote me that i can't remember everything..
Ali has my maps maybe he can shine in.

The new setup will only on e85 with 10.1cr stock na headgasket should be fun.

Sherwin you will be one of the first people that will see it once i get it togheter.

As was said, the car was never tuned above whatever 18 psi or so it normally ran, I may have the map somewhere (i will look it up later on if I still have it), maybe more conservative timing may have helped but probably not much. I will say it was definately still pulling hard at that boost level so it couldn't have been that far off from the right values.

most don't do it because you do not need it to go fast and it is very expensive. harness relocation is very easy you can put it under the runners with very little modification, just need to move the TB wires around.
Yes they make them for na-t, no the greddy one for a 2jz-gte does not bolt up to the 2jz-ge head, but there are plenty of front facing manifold options for na-t made by many other companies ranging from $600 - $2000 and lots and lots of na-t people do run them, I dunno how you haven't seen one yet.

I've read Meth/H2O injection is dispersed more evenly through NA mani too. if ur running single nozzle. I got single nozzle and it works great on the NA mani.

na intake manifold is also good for extra torque up to 4500 rpm's. more torque = better

Ali when brad was tuning my car he told he to get a wg from the stock twins and he will set it up on my cvar with the butterfly valve and it will work like the QSV.
He had mine hooked up and it worked great.

thats cool, yeah you can use a wastegate to turn it on and off mechanically based off of vacuum/boost i think thats what he was doing.
The aem though it is already wired up to control it like the stock ecu but the settings are wrong in the cal file, but its real easy to change it and it does spool very hard i will agree with that.

With the stock settings it acts like a quick spool, but then it never turns off and hurts the top end. Its supossed to act like a quick spool, and then turn off so you can reach even higher hp/torque in the top end, once you change the settings it really does pull hard from 3k to redline.
Kurts dyno shows like 30 ft/lbs of improvement up to 4500rpm over not using the valve.
I think thats pretty impressive since the graph shows a max of 390ft/lbs, so its close to a 10% increase in torque right when your turbo is spooling up.

18psi is still pretty high for 9.2:1 compression and 93 octane.
18psi is usually the safe limit people use for 8.5:1 compression on 93.

have you done a lot of EMS tuning?

i'm interested in the details of the e85 setup.

I ran 9.8CR on my SC with 19lbs and no problem.

I ran 9.2 at 21lbs again no problem lol.

Lexforlife (ED) ran 19 lbs on 9.2 CR and no problem so far, Alpha tuned his car and Alpha recommended TT HG over the BL 2.5mm.
He went thru couple BL2.5mm.

Stay tune for the new setup.

If you don't mind me asking are you thinking about na-t near the future? i am just asking....
