Lol we can speculate all we want. Gtm still hasnt replied to any of this.

I did read the Op has received his refund, Thats GREAT NEWS.

Im very HAPPY for him. :)

For those who maybe still waiting for an update or a refund? I can only hope you people get satisfaction either way.

I would suggest to PLEASE PM AK to let him know of your refund situation so he can do whatever he can to help.

Everyone else with NO issues here? Please feel free to move on WE don't need more countless pages of more OFF TOPIC replies. :ugh2:

Almost everyone who's had an issues or an opinion? Has been given the opportunity to voice their concerns as well making others aware of a "potential" issue with this vendor.

I would appreciate it as well as the other members whom are still in the group buy list to KEEP IT ON TOPIC!

Please read the Op's original post so there's no confusion


Thank You.

Hey 1slow370 I thought that was funny when you tried to tell Charles how to build a fuel return system.

Lmao

Thats Ford vs Holden dude! And don't you f'ing forget it!!! ;)

So what your saying is F.I's kit would be better if it were a bit worse? :rofl2: I agree you are cutting down the longevity of the motor at those power levels however, no one really knows how long the motor will last.


Sorry trips I had to post this

So, who's still in this thing? I'm paid up in full since June last year. I know some have got refunds etc.. anyone swapped over to a supercharger kit instead of waiting longer?

What's the wait time on a SC Kit from GTM nowadays?

not sure, didn't end up asking was just something in the back of the mind.

unfortunately for me, RHD here, so can't go with any other turbo kit and supercharger is the only other option, was so excited for this kit though haha

I did in mid December and I STILL don't have my SC. Get your money back as soon as you can....IF YOU CAN !!!

You must know Alkatraz!

Mikey lives just down the road from me actually. Of course that road is 4300km long but yeah we are practically neighbors. :ugh2:

Wow, were you in this group buy and paid then decided to get the supercharger instead because of the wait?

lol me and Alkatraz are neighbours as he said ;) don't you know every single person in your country? :P

To all saying it's the high TQ that kills a motor, you are correct, BUT.... Horsepower is simply a function of torque at xxxx RPM. More precisely, HP = (TQ x RPM)/5252 :tup:
Also, F.I. has done their due diligence and it is just paying off for their customers, that's all. Nobody truly knows the limits of the stock block until a kit like Tony's meets a Specialty Z tune and the clock ticks forward. Haters gonna hate.

It's not hate, it's just a fact. There is a torque limit at which the motor will let go, whether it be from an issue or simply metal fatigue from high cylinder rpressures. Are the FI kits over that? We'll see. Time will tell. At the 600whp level, it's not going to take much of a hiccup to take out a motor.

So let me get this straight.. What FI turbo kit owners are saying is 600 WHP is safe with FI kit but with GTM kit you will kill the engine with that power? :shakes head::shakes head:

I think it's that the FI kit makes more power out of the box, and there haven't been any failures yet. Granted, I'd be shocked if anyone had more than 5k miles on those kits. Again, time will tell.

ofcourse they will make more power out of the box. just look at FI kit and compare it to GTM kit they shouldn't even be on same sentence, totally different category, and not only that. their kit use bigger turbo too (GTX2867 compared to GT2860)

I just find it childish to argue about FI kit will handle 600 WHP while GTM kit will pop your engine with that power..

Yep, it's funny that there's a brand as far as how much power a motor can take. :rofl2:

^It's about more power on lower boost, and therefore efficiency per unit of added air and fuel, not the absolute figure. 9psi on two disco potatoes is 9psi on two disco potatoes, whether that's from a GTM kit or an F.I. kit. Difference is in the what makes up the rest of the setup and the quality of the tune.

And the stage 1 FI kit still uses 2860; GTX turbos are an extra-cost upgrade.

Yes, but the cylinder pressure doesn't care about efficiency. There is a limit for everything. Again, we'll see. That's a large torque increase for a stock NA motor.

Agreed. Like I said before, time will tell. :tiphat:

So what youre saying is if I installed Garret GTX55 and have 700 WHP with 10 PSI or so it will be safe for my stock engine? :inoutroflpuke:

Let's see you fit it in the engine bay, first. :bowrofl:

torque is what killed stock 350z motors and it will kill our motors eventually

the only thing is how much torque does it take to kill our motor, with the old DE motors, 400wtq would send pistons out the bottom, didnt matter if it was n2o, turbo, or supercharger, the HR and VHR seem to do better with handling torque but there is still a limit to everything, just we dont know that limit yet

I was comfortable with the DE at 450tq personally. I ran it that way for a long time and when I tore it down to do the build, the internals and bearings looked perfect! So good in fact, that 10 years later I still have them saved here to look at as a testament.

The VHR not only has slightly beefier parts, but it makes less torque than the DE generally. I am assuming it has something to do with the valve timing / cam profile that is hurting the boosted torque. But it definitely has some to do with the intake manifold... the VHR intake manifold has much shorter runners than the DE... somewhere between 1.5 - 2" shorter.

Between the lower torque, and beefier parts, I think the VHR gives us a far more flexible platform to work with. This is probably why there are VERY few engine builds around here. With the 350z DE... within the second year EVERYONE was building their engines.

We also have a higher redline, giving us more room to take advantage of RPM. I really think 600whp is a pretty safe area if the tune is well done. If I were a better tuner I would have pushed mine further by now. I think I will go a little higher boost in a couple weeks though to see what happens.

Oh yes some of us do... lol

But you're using E85 so wouldn't that provide extra protection against detonation and burn cooler than gasoline allowing you to get up to 600whp while putting less stress on the motor compared to gasoline?

I'm thinking of switching over to E85 as well just not sure if I can use regular gas in an emergency situation and what it would take.

It is a given that you need to make the power you want to make without running into pre-ignition events first. I don't personally know if anyone has tried to make it to 600+rwhp with 93 on the stock VHR or not.

E85 increases knock resistance so you can run the proper ignition timing to achieve peak cylinder pressure at optimum crank angle. With 93 octane, you might find combustion to loose stability before reaching optimum ignition timing. Which, BTW, isnt the same for both fuels.

Decreasing cylinder pressure would decrease chances of pre-ignition, so there are bits and pieces to be taken from all that.

Like phunk is saying. We are not increasing the blocks capacity, rather we feel that it is misrepresented as I really do see too many canned tunes or just plain stupid tunes(really 11+psi on 91 octane, even with meth/water, you are asking for it) wrecking perfectly fine engines. I know many of us FI guys are VERY fortunate to have Seb@specialty Z who has tuned Z's for generations and has an outstanding track record with the z34.

Do not know why this bothers people so much. Haters gonna hate, i guess.

Wow...i thought this was Cosmo's thread......can we just let this one die already....totally did not mean to jump into this thread.....FML:shakes head::shakes head::shakes head::shakes head:

Unsubbed:wtf2:

^ this guy.

You're assuming people are bothered. It's not hate. Don't get defensive. Everybody who is running that much power is pushing the envelope. That's great. That's how advancements are made. But at some point, even with the best fuel, tune and hardware, a rod pretzels itself just from the torque. No one WANTS this to happen. But as people push limits, eventually someone will FIND the new limit.

^well said.
No one is hating. The FI kit is amazing. Only going by what we've seen so far from others experience those numbers seem really high for a stock block. We just wanna warn you of the possibility with such high (amazing) numbers.

You're the one who needs to calm down. Nobody called you a retard. With you calling people "wannabe tough guys", you're doing nothing besides exacerbating a non-existent issue.

:confused:

thats May 11 in the states. i never knew other countries celebrated that or even cared...

We all came from somewhere

Lol why wont we care? I guess we have different dates that's all..

Mother day celebrate is 3/21 here in UAE.

Yeah looks like he changed it.
Edit: nevermind. looks like trips changed it.
