My Greddy TT install will be finished tomorrow. However, I don't have the
E-01 yet to tune and address the timing. Will the car be okay to drive for a week until I get the E-01? The reason I ask is because I've read that someone in the past blew their engine on their first run right out the shop because they didn't have the ignition harness.

Another question is, what are your opinion towards turbo timers? Yes or No?

 

I wouldn't run it. Unless they are completely and properly set up, the Greddy TT kit is an engine popper. Patience my friend will pay off 10-fold.

Turbo Timer is not needed, but nice to have.

 

If you are going to be driving hard and not be able to hang around the car while it cools down then you need a timer.

You will be fine without the e01, I would at least install a boost gauge even if it is temporary until the e01 goes on because most of the failures are probably due to boost spikes due to install issues and bad wastegate hook ups, at the very least see if the shop can hook one up while you test drive it.

 

Should I be worried about driving the car without addressing timing or A/F tuning? I would have to wait a week until the E-01 comes in. I know that boost spikes and not addressing timing is one of the main reasons for engine failures. Westpak, Boost, EGT, & AEM Uego gauges will be installed before it leaves the shop.

If it's okay to drive the car without retarding the timing, is there something I should not do, eg:WOT?

Another question, should I wait till I get a return system to install the Walbro fuel pump or is it okay to install it first?

 

Welcome to the F/I world! Yes, you should be worried with an out of the box Greddy kit. Driving it fine...boosting it is not. So just cruise around and stay out of the boost...it will creep up on you fast.

Get the timing harness, get the fuel system, and most importantly, get that thing tuned before you beat on it. The Greddy "tuner" kit has destroyed many motors in stock trim, so dont take these precautions lightly.

Hope that helps, and feel free to contact me if you need more advise.

 

Sharif, so you are basically saying I will be fine as long as I don't boost at all or don't boost as high? If your saying to not boost at all, then I think I should just leave the car in the shop. There is no way I will be able to stop myself from hitting that throttle

-The ignition harness+diodes and CAS wire is installed already.
-The Profec E-01, Ext. signal harness, pressure sensor harness are on order and should be here by next week.

 

Why take the chance?

Just let the car sit. Maybe you get away with it, maybe you don't. The maybe you don't will cost you thousands and far greater than waiting 7 days for the fix.

 

Why take the chance? Because I have been taking the NYC transit everyday for almost 3 weeks to work and back. My feet are starting to hurt standing in the train with a car full of people that were sweating all day.

I don't mind taking another week of public transportation if it is even a little bit unsafe without addressing the timing.

What would you guys do?

 

I wont worry If the install is good there should not be a problem. but its always at your own risk

 

I ran my car about a week without the e-01. It ran perfectly fine, but I didn't go into boost at all. I think you will be fine, but then there's always that small chacne... but that might just be me since I always want to be safer than safe. If you don't mind taking the transit for another week then I'd say just do that and then when you get your car you will be completely finished and won't have to go back to the shop or anything.

To answer your other two questions, you can install the Walbro fuel pump without getting the entire return fuel system, and the turbo timer is a good thing to have... I am installing both of those things this week.

 

I would not take the chance. Some have gotten away with it but you might not. What's another week? If you blow the motor your car will be down for another 3 months.

 

man don't take the chance! i wouldn't want to hear of you describing how you blew your motor and who and where can you get parts to rebuild. just take the transit until it's done because if you blow, you'll be taking transit for longer than one week.

 

if he doesnt boost, it will not blow.

 

I just a few questions about the greddy tt kit as well. i talk to Kyle and several of his techs all the time from SGP racing here in houston. I was told that the kit is pretty good right out of the box. They told me that they would recommend certain items with the kit. like boost gauge, BOV, exhaust, and fuel pump. i asked them about tuning and stuff. they told me they do all the tuning and everything to insure safety of ur vehicle. pretty much all they do is Z's. they have like 17-19 Z in the shop right now. as from ur experience what do u think? is it necessary to change the fuels system and etc? i understand if u going higher boost and power, but hey? thanks for your time,

Its not impossible to get a good tune out of the stock greddy kit with timing adjustment and a fuel pump at stock boost. It's just safer and more reliable with a return fuel system. I ran my car at 8.5psi with just a fuel pump, timing harness, and good tuning, but I wouldnt recommend that for a customer car. Remember that running the car on the dyno is one thing, but making it last under the abuse of a customer is something else.

 

You should be fine on stock boost and without the E-01. Just make sure you keep an eye on your boost gauge for any boost spikes, and EGT.
