Is he full of $hiT?????NEED HELP

[Blaze696]

i am looking into buying a 95 GS-T from a person on ebay. While talking to him bout the car he said this to me, "Race gas has more octane so it burns better, which is why you can push more "boost" into the motor." Refering to turning up the boost on the controller. Is this true or is he preparing me for a problem when i turn the boost up on the car???? I am going to test drive the car on monday so if you have any information about what i should look for while turning the boost up, or just test driving the car PLEASE message back as soon as possible. He also said the car is run at 15psi right now all the time, should you keep a car at that level or is that a possible problem? Mods include a frount mount intercooler w/piping, evo 111 turbo, downpipe, 550 injectors, intake, SAFC, AVCR. ------Thank you

He is right about the race gas being at a higher octane and the boost thing is the funniest part because that motor is probley not built worth a shit. if thats all for the mods that car doesnt have a built bottom end so if hes running and kind of actual "race gas" hes more than likly full of shit. he would of burned that motor up. he probley only running like 93 octane pump gas. so tell him that he is full of it and offer him 1000 bucks less and say give me a call when you want to sell it.

Race gas, or higher octane fuel, produces lower levels of detonation, or knock. Generally yes, you can run more boost on better gas. Is it safe, welllll, not really.

Since the guy says there is an aftermarket turbo on the car, check out the area around it. Look for ANY oil leaks, or "burnt" areas, caused by an exhaust leak.

Listen to the area around the timing belt for weird noises.

Open the oil cap (with the car off!) and smell. Make sure it doesnt smell burnt.

The AVC-R is an electronic boost controller? No? I would stay away from those, and go with the caveman style (sorry Geico) manual boost controller. Tell him to keep it and maybe take some $ off the price.

I run 18 on 91 and 26 on 110. That should answer your question.

Holy shit batman!

 

[Defiant]

Higher octane = more additives = less gasoline = higher consumption = more deposits

Still, sounds like a shaky story. Keep shopping.

Thats the least of your worries buying a used DSM from ebay.

 

[Cs4g63]

This makes me think of the jacka$$ that was selling an eclipse with a "EVO 8 TURBO" on Ebay. Even when he was questioned as to why his "EVO 8 TURBO" looked like it was a EVO 3 16g he still swore it was an EVO 8 turbo. Some people just try to get away with whatever they can.

 

[bling5tatus]

I would avoid turning the boost up right when you get the car, I'm sure others here will agree.

Those mods are MORE than enough for 15psi on a stock long block. You could certainly jack up the boost, IF you have a logger. That is why everyone is doubting. They don't see timing curves and % IDC on the web to tell you what'll happen. If you are logging good injector % duty cycles and no knock, then you can yank on the boost w/ in reason and definately get more power than what 15psi and a stock short block can deliver.

Where is this discussion of race gas coming from? More people than you want to know run a fmic, evo3 turbo, 550s and safc at well over 15 psi daily driven w/ pump gas. These engines are famous for that kind of potential. If you have a logger, then you'll know for sure what is going on in the engine bay.

Is there a fuel pump upgrade? If not, then limiting your boost to 15 or so psi w/ a stock long block is probably best until it is upgraded. Still no need for race gas. When you get a logger and a fuel pump you can likely run 20+ psi like most of the rest of us do w/ pump gas and a decent tune.

To add, all mitsubishi 4g63s are "built worth a shit" straight from the factory. The 2g block can handle upwards of 450 whp and be still daily driven. That is FAR more than what that evo3 16g can give you. If you want to push 20 psi, I recommend geting some ARP head studs. And a new OEM (or fel-pro composite) headgasket. Other than that, there's no "building" neccesary, to reliably run much more boost on the street w/ pump gas as is.

How much boost has this car been run w/ pump gas? If no more than 15psi, then it hasn't been abused at all. I had run 15 psi w/ stock pump, stock 450s, stock 14b, stock sidemount for years.

EDIT: to add, Defiant is so correct from my experience. Running race gas really gums up over long periods of time. Depending on the lead content, your o2 sensor will fail prematurely and other isses can crop up. Not sayign race gas isn't great , but so is a logger and a good tune .

 

[Blaze696]

Thnx for all posts. I forgot to add the engine is a 6 bolt w/ 45,000 on it, body & tranny have 90,000. What kind of value does this add to the car or what price range is reasonable for the car w/ mods.

 

[92 GSR-4]

Lmao. I run 19PSI on my BACKUP car with a B16G, stock sidemount, and 550's. Not a ping of knock until I heatsoak the stock IC. But that's besides the point.

This guy sounds like he's taking you on a trip. With his mod list, he should certainly be able to run 15PSI on pump gas. The fact that he claims to up the boost because he is using racegas raises some bullshit flags in my mind. And why the hell would he turn the boost up when you come to drive it? I would get an experienced DSMer to look at this car with you also, because I can bet you he's blowing smoke up your ass about it having a 6-bolt. I don't think some dipshit who daily drives a car at 15PSI with racegas has the intelligence to complete a 6-bolt swap. But....if you decide to check this thing out, do these things BEFORE the purchase:

1) Compression test it yourself!
2) See if he even owns a logger. Ask to log it while you drive.
3) Show up with a case of oil and a oil filter (Fram# PH3950 for a 6-bolt) and tell him you want to drain his oil into a clean container and cut his filter open. Look for shavings.
4) Try to verify all the mods he has done. If he says he has a EvoIII 16G, try to do the research about the casting numbers, just so you can make sure he really doesn't have a 14B or some other look alike.

If he gives you flak over these steps, be firm and tell him it's a freakin race car that you know has been beat on. If he is confident in his car, he should have no problems letting you inspect it meticulously before you purchase. Good luck!

I think this car is more then worth the money he wants. Thats just me. He doesnt seem like a total idiot like some of the people posting on here are making him sound also.(ther the idiots)

 

[Pro3racer]

I agree, the people on here are the ones that are being idiots. I run race gas at the track, but don't turn the boost up, i just have the gas in there to make sure nothing happens to the motor(basically a safety thing). Yes you can turn the boost up with race gas, as long as you tune for it. The seller seems to have a pretty decent car, and he was right with telling you about the race gas thing, but if he is DD with race gas, at only 15psi, well, he was just wasting money and wrecking his o2 sensor.

AMEN!!!

Running on the street w/ what you can get away with. and running at your full potential is two different things. On the street, It's a bit hard to ring out your setup enough to blow it up running pump gas w/ such a setup. If you do, then you're likely putting yourself and everyone around you in too much danger to warrant the efforts, at the least.

Regardless of race gas or not, his setup is worth the money. As I said, there's no bs here. He can sell you a car that can run 15 psi on what he mentioned. And it looks like that it can handle what he's giving to you.

 

[Spyder4g64]

25psi with race gas? damn. im impressed with that figure. WTF

 

[95tzlgst]

You should find one stock from some old lady for cheap that way you don't have to worry about anything put on wrong, thats were I made my mistake.

 

[Cobrasatellite]

Im still relativly new to DSMs but the drive should tell you alot. These cars from my experiance dont hide problems well. If you do it wrong it wont work or runs noticably bad. Also if we all bought from "little old ladies" there would be no point in the classifieds on here. Talk to the guy about his mods and reson for doing what hes done, see if he knows his stuff. And ask what DSM forum he uses. If he dont have a forum DONT BUY THE CAR. Just my opinion.

 

[92 GSR-4]

25psi with race gas? damn. im impressed with that figure. WTF

Let's try 25PSI without racegas! Yep I drive it on the street too.

Some people aren't idiots here, though there's a good bit. I would get educated FAST, or find someone educated to look at the car with you. Plain and simple you need to find out if it really is a 6-bolt, if the mods he says are there are really there, and do a compression test.
