How many went FI and blew a motor?

FortuneLSX-TT

I blew mine a while back.

I installed the turbo kit myself the first time. Then I got an exhaust leak and got lazy and had a shop pull it to change the gaskets on the headers. They weren't as careful on the routing of the vacuum lines for the boost controller. One of the vacuum lines got a hole burnt into it and the boost controller controlled no boost that day..and let's just say 16.6psi was more than the stock block could handle. Needless, to say I handled the installation of the new short block. Good shops are getting harder and harder to find these days.

This... LOL!

We are not Honda Civic drivers who buy a FI kit off ebay and install it overnight in our parents garage only to have it blow up in your face the next day trying to be a drift king.

I'm thinking of a Stillen SC install over the winter. Totally unconcerned with reliability as I have no need to be the fastest 370Z in CT. I also have a quality shop to install it and tune it properly. 400whp is fine with me. Hell, my car is fast now. Looking forward to it.

Hey man I'm in CT too and I'm looking for a place to do my possible FI install, who do you have for your install?

SS_Firehawk

Well, with the amount of money I blew on my setup, I drive her hard. GTM felt very confident letting her go at 550whp, who knows what she's making now on meth (they did that too). Tuning is super critical like everyone says. For what was an NA V6 to make this kind of power on stock internals is impressive. The 6MT, while I won't say is bullet proof handles the power just fine. If you didn't cut corners in the planning and don't get power hungry, you'll be fine (95% of the time)

True Dat. You can't go wrong having GTM do the install, for sure. And Nissan did not cut corners on the internals, hence the reliability. If you had told me three years ago that the VQ37 could be fed 12psi reliably, I would have been like gtfo.

I Babied mine only got on it once and a whole cly3 took a dump at 457WHP.

I've always despised the phrase: "He BLEW his motor!" 99.9% of the time HE didn't do this on purpose, the motor blew.

In my case this is only partially true. I drove it 20 miles before it completely locked up. LOL! Crank bearings = NFG.

I ran five HARD passes at the dragstrip attempting to get ONE clean run. Each time the friggin' fuel cut or some limiter come on and then went off. Almost always in second gear. This has happened in the past, and Jimmy (my builder) told me to hold it up there a little higher. Last Dec I did, and it went 11.13et. Twice.

This time: not so fortunate. Working boost guage with memory never exceeded 15.8 lbs, despite twisting it a turn. Jimmy's convinced that did it. I'm not. It barely went 120mph in any configuration.

I was trying to better the 11.13 time. So STUPID close to the tens, I HAD to try. Wouldn't you?

I had installed 4.08:1 gears and considered this to help. Truth is, on the street this is a GREAT mod. At the track, it didn't let the engine boost OR work. I'm dead certain that was the wrong direction. For me. But I had to try it to find out.

Play with fire. Yes, same components I ran before.

No excuses. The dragstrip is HARD on parts. Five runs in a row flogging it didn't help. (All but one were in the mid elevens.)

The car was smooooth as silk and ran stupendous with over 550whp, until 'I BLEW IT' by going to the strip. LOL!

That is all. I'm searching for an OEM engine and will be parting out the performance parts. Soon.

Mr.Squeeze

Again Coop sorry to here about you built motor failing as I have stated on the G37 forum. The thing that really sucks but stands out is a bearing failure that makes me think oil starvation (burning some oil) or improper clearances during assembly of the engine.

I really hope everything works out for you this just really blows.

Sharps built motor failed?! O_o

elperuano

He caught it before he went BOOM

elperuano

FireDan ur numbers were with race gas correct?

SS_Firehawk

There is efficiency to be had with a larger single turbo compared to twins as well, but yes, like Elpuerno said, he was using race gas.

I remembered he was. Would benefit everyone for him to disclose that. Can be misleading and have guys thinking they can make the same powers on pump gas.

Boosted Performance

You guys should not be hung up on psi vs. whp.



There are a few variable here. One that is mostly overlooked is the type of dyno used. DJ is somewhat the industry standard, but there are other dyno brands that will read a lot lower than a DJ, and a few that will read a lot higher than a DJ. So the power between the lowest reading dyno out there and the highest could be as much as 20%. In the end, each dyno is a tool used to tune a car, and the best way to find out the power a car is putting down is take it down to the drag strip, and make a few runs.


There are other things to keep in mind as well. Fuel (especially race gas vs. 91 pump gas), weather conditions/temperature can play a big role, as well as the tuner himself and the way the dyno is set-up. Some tuners for example do not feel comfortable exceeding 420ft/wtq on these engine, and other are more than happy pushing things much further than that.
