Hey guys. Buying a GReddy TT with FMIC from Sharif. I also intend to buy the Walbro 255 Fuel pump and the fuel return system. I am shooting for 400 RWHP or so. I intend to put in a stronger clutch and flywheel and a LSD most likely.

So my question is, if I am going to have variable settings, a low boost street setting and then a "crank up" setting, will this setup be fine for the 400 RWHP without a risk of blowing the engine apart? Or should I put some more backup systems in the engine? I know something about wire coatings and such. But will the stock block hold 400? I really have a hard time believing that. With the GReddy blow ups I have seen I just don't know if I trust that claim. But lots of people are saying if it is a good tune and not constantly running at max boost, no problem

~Josh

 

Stock block will hold 400 rwhp.....but for how long. IMO, the greddy kit is just a bomb waiting to go off on a stock motor. I know if can be setup to run reliably, but the reality is, we are seeing a lot of posts about blown motors with the greddy. that is why I chose the APS TT over the greddy.

My advise would be to save up and get forged internals for the greddy and find a GOOD tuner to get it setup right

 

The block will hold the 400whp no problem. The most important thing is to make sure you get a good shop to install and tune the kit. Also make sure you get the extra's needed. Since you are buying it from Sharif, I am sure he will not forget to tell you about these items.

Ignition Harness
Pressure sensor harness
CAS wire
Fuel return/walbro which you stated already.

If you are only looking for 400whp, I would recommend you skip the emanage all together and get the Technosquare Greddy TT flash. It is set up for 8psi and addresses timing. I have seen several guys go this route without any engine failure. You can pay for the flash by selling the emanage + a couple hundred out of your pocket. Tuning costs $125-$150/hr and usually takes 2-3 hours so you will save if you go with the flash.

Good Luck!

 

josh-

sharif will be able to steer you in the right direction as far as what you'll need to attain the 400rwhp mark...

really, you should go with forged internals for a bit more safety (but even having forged internals does not make these setups bulletproof)

if you are gung ho on staying with the stock motor...many have proved that you CAN run this kind of power for at least a year without problems (i don't know of anyone yet who has sustained high power with a twin turbo for over a year without either blowing their motor or choosing to rebuild- before they don't have a choice in the matter)...with the appropriate goodies...

just like on the other thread of choco who just blew his motor...be wise when you get your setup--learn from everyone elses' mistakes (mine included)

address the fuel issue--get a fuel return system that can delivery more fuel to keep things safe with the A/F...contact charles (phunk), his system is THE MOST COMPLETE!!!

if going with the e-01... you'll need the timing harness to pull timing out (with diodes from radio shack)
the pressure sensor (i think that's what it is called)

....this alone will improve the safety of the kit a ton...

get a blow off valve as well (the greddy kit doesn't come with one)

hmmm, what else...tune the car...tune it well...talk to sharif or charles reguarding this matter-

hope that helps

 

yep..that is a better solution--if you don't want to mess with the tuning

 

It is not Greddy's fault that motor keep blowing up. It's all about the tune. (Peter don't get pissed off about what I am about to post) I am sure if the APS kit came with a piggy back that was as tuner friendly as the emanage you would see APS TT's blowing up too. This is not a bash at APS, but anyone can buy greddy software for $150 on the internet and they are free to tune. I am sure you can get the software for the unichip but it is not as easy as ordering on the internet and from what I have heard it is a lot more expensinve....something like $1000. They are too many greddy kits out there with no engine failure to blame it on the kits. The APS kit comes pre-tuned by a highly experienced APS tech.

 

not to get off topic, but do you have a link to the tuning software???

THX

 

BTW, if you are only looking for 400whp I would recommend the APS TT as it is the most complete kit on the market and everything is plug and play. It is capable of more than 400whp but I won't get into that as I don't want Peter to think I am anti APS.


See Peter, I am not anti APS. I just recommended your kit to someone because I think it best suits his needs.

 

Why? Are you going to mess around with your tune?

Here you go.

$115 for the software, cable, and instruction manual.

 

Good point, Brian has done some safe tunes for us. Someone told me about rod bolt/main bearing issues over 380whp so I would try to stay in that power range for oem motor longivity.

 

With the APS system.. is it still backordered to high hell?

 

your best bet will be to contact GRD performance. They are a major stocking dealer.

I'm definitely not trying to take over this thread with APS this and that but honestly if all your looking for is a reliable 400 rwhp...then you should look at APS and either their single or twins. Even turbonetics single T should do the job. Sorry I feel obligated to tell you this for your own sake. If you have plans on building your motor then I'd recommend any kit. Also if your considering the APS single at all there are only a couple days left for the promising groupbuy. Here is the link and good luck in whatever you decide to go with.....http://www.350zmotoring.com/forums/s...t=25969&page=1

there are only a couple of spots left - just thought I'd warn you

it looks very promising that we'll be getting the APS tallboy plenum along with the discount for a total of 1k savings. You would need to call them up first thing tomorrow morning if you wanted to this route and put a deposit down for 1k to secure everything. I beleive the GB was extended from Friday so act quick if this is the route you decide to go...

 

I know the single will have more "boost lag" but should technically be more reliable. Less moving parts and all. Aside from that any large differences in the two setups? I know search the forum but if I want to do it tomorrow I better ask

~Josh

 

The boost lag for the single is not much different than the twins...one of the beauties of the APS single....go to http://www.************************/35.../it_system.htm to check the graphs. This has been the most anticipated turbo for the 350z (or for me at least ). Its not everyday you see more than 20 turbos being sold in a groupbuy. If you have any questions please feel free to ask...... This is the most complete turbo kit out there and it'll be hard to beat in terms of reliable performance....

 

From what I have read there is no boost lag.

Read here about the TT kit.

Read here about the ST kit.

See the single turbo vid here

Now make up your own mind. This is $5300-$7500 of your money not anyone elses.

 

Both of the APS kits are comprised of mostly the same components. The twins come with new exhaust manifolds....

 

Oh one other question. What Octane are the APS units tuned for? In FL I can get 93-94 octane anywhere I go.

~Josh

 

You can get a map for 93 octane. Just let them know when you order what map you want.....I am sure they will ask you though.

 

Out of the box they are tuned for 91 I believe...but Tuan at GRD can switch to 93 at your request. I'm near Tampa as well (Bradenton)
