eNVe's LGT Road to Discovery


Recommended Posts

I finally had a chance to do a proper bonding with my car yesterday. It got it's first car wash under my ownership. I don't really feel like I own my car until I sit down and do a wash and wax session with my car. It's almost ritualistic. I end up finding out a lot of things about my cars when I do it. Where the imperfections are. Where all the scratches and dings are. Where things look odd or different (an aftermarket part, perhaps?). Whatever it is, I feel like an LGT owner now.

 

2005 OBP LGT Limited 5MT with black leather interior.

It's a little dirty on the inside, but I'm making my way around to it. I love this car.

Ditch that SPT Intake and get it off the stock tune. Looks like a stock turbo as well? Car has every dealer add on ticked. Turbo timer is obviously aftermarket. Welcome!

 

Lol. It does. The previous owner was quite proud that he only put Subaru products on the car (despite some obviously non-Subaru products). It also has much of the Spec.B suspension underneath it. I asked about the turbo, and he said it was the original. I have plans for the car, but I am still getting a feel of the waters.

That turbo timer really just set the tone for what you can expect from this car. Says alot about the previous owner.

 

What wheels were on there before, or do you know? Those wheels are not Legacy wheels, and certainly not from 05. I wanna say. . . '10+ Impreza?

What do you mean? This is my first turbo car. Do you mean that the previous owner beat on the car?

 

The wheels are from a '13+ Legacy sport. It had BRZ wheels on it when I saw it in the ad, but had these when I saw it in person.

Turbo timers aren't necessary on Subarus because they aren't oil cooled, they're water-cooled; thereby making a device to keep the car on (and the oil circulating) pretty unneccessary.

 

Means he (they?) had absolutely no clue what they were doing, they just wanted to throw money at it. Depending on how long that intake was on there and what the driving habits were like, may not have even needed to "beat on it" to put it in poor condition.

This comment doesn't sound right. The turbo still has oil going to it for lubrication. Hence the whole debate on removing the banjo bolt filters from the oil lines to extend the life of the turbo because the banjo bolt filters clog up. The reason they clog up is not usually due to debris, but due to oil caramelizing on the filter, and eventually clogging it up. The reason they caramelize on the filter is because the car gets shut down with the oil/turbo too hot, which then just sits in the lines/turbo and burns onto the inner surfaces. Thus, when there is no oil flow, the bearings get too hot due to friction because of the lack of oil, and they degrade and die. Now you have a dead turbo.

 

Even if you remove the banjo bolt filters, you would still get oil caramelization inside the turbo housing, which would increase friction, degrade turbo performance, and could ultimately lead to premature turbo failure.

 

So, I wouldn't necessarily say the guy didn't know what he was doing. It looks to me like he knew exactly what he was doing. He was just silly with what aftermarket parts he put on. I'm sure that if SPT had a turbo timer, he probably would have used it instead.

 

Also, even if it were water cooled, the water doesn't flow unless the car is running. Sure, there is some thermal driving head, but not enough to say that it has sufficient flow through the system to cool it down. Otherwise there would be no need for a water pump.

 

EDIT: In retrospect, I do agree that the turbo timer is a little overkill, especially with the level of modification done to the car at this time.

There's a reason they don't -- for the exact reason I stated above: Subaru turbos are water-cooled.

 

Yes, there's oil in there, too, but, being also water-cooled negates the need for a turbo timer.

 

The purpose of a turbo timer is to keep the oil flowing through the turbo -- when the engine stops, the oil pump stops, and so does the flow of oil. It's less about the banjo filter, which isn't on most turbo cars, and more about the actual journal bearing itself, which, when caked with caramelized oil, yes, will kill the turbo.

 

The need for turbo timers is actually for aftermarket turbos on Hondas and 90s-vintage Mitsus, ala Eclipse.

 

Our water cooling system operates on a vacuum of sorts. I don't quite know how to explain it, but, it's due, in part, to the reason why our turbo coolant reservoir is the highest point in the system, and why it MUST be the highest point in the system in order for everything to work as it should.

Seems like this thread is getting out of hand. The previous owner seemed to take pride in his SPT parts and now the new owner can benefit from his losses. The parts aren't bad and are certainly better than OEM stock parts.

 

Welcome to the forum and to Subaru land eNVe.

 

Spend most of your free time on here learning about these amazing cars and you will have no problems figuring out situations and asking questions regarding your Subaru.

 

All MrTris is saying is, the turbo timer is not useful on our cars all it will do is waste Gas and put more stress on the engine for no reason. The timer will do more harm than good on this car. We are just giving you the info and it is up to you to run with it in any direction.

 

Once again welcome!

Not what the guys at Outfront Motorsports told me. They make 600 hp subie engines. I think I'll listen to them.

 

A 600hp car has a front mount or some type of v mount,air water setup etc. no need for the engine cover when you remove the top mount. The cover is designed to fit the under hood shroud and make sure only clear air hits the intercooler. When removed you just have air splashing into the bay thus. It is an integral part of the top mount system.

 

Anyone who tells you otherwise would not be working on my car. I'll trust a Subaru engineer over Bill the tuner at the local hooptie shop.

They're far from a shade tree mechanic. He's been building Subaru engines since 1990 and have quite a resume. Others have tried to copy them and now most in the southwest go to them. I don't understand why you would be arguing over a cover that is mostly aesthetic anyway.

Well, with the way the hood scoop is positioned, it directs the airflow right into the intercooler. And I agree with you. But, would you rather take a chance of deteriorating all of the rubber and plastic connections for something that is mainly for appearance?

I'll call you both out and say that neither of your opinions matter because the hood scoop is useless on our cars above 80mph.

 

Best thing to do is get a front mount for maximum cooling. But if you do have a stock top mount keep the engine cover on or buy your own Air dam to channel air into the intercooler square.

 

I really don't care about "melting plastic" my friends car has 200+ Miles on his stock engine cover and it hasn't melted. I'm sure any Subaru guy that thinks they are the Chairman of FHI will always want to chime in on their new genius theories they have come up with.

I appreciate the debate, but I'll do some more research and see what convinces me is right.

 

Anyway, back on topic.

 

Thank you for the welcomes! My plans for the car are to make it look stock while I upgrade it. I was rather disappointed that Grimmspeed discontinued their port, polish, and coating services. I'm going to do more parts research. I'm still deciding specifically what targets I am hoping to reach. It'll be my daily driver and track car. I've never tracked before, so I'll do some track days before making any final decisions.

 

Until then, I'm going to freshen up what's already on the car.
