Turbo Explorer????????

[lo_jack]

I agree with James T. Almost all factory blower systems are running at single digit pounds of boost, because at that pressure is a compromise of driveability and performance gain. People who destroy pistons are using too much boost for their engine. Phoenix is right, you must be aware of what your engine was designed to /can handle before slapping a blower on, but a mild boost is less likely to cause giant malfunctions. On the other hand, a mild boost is less likely to get you the horse you want, so then we are back where we started; "is it worth it on a 4l explorer?"

Another draw back to a turbo is that I have seen so many kids blow their motors by upping the boost. On a turbo charged motor it is so easy to just up the boost but people for get more air and not enough fuel POP!

well his blower came with a FMU system, air scoop for underneath to draw more air, oil cooling system, external fuel pump. after he took it out and complained to the company a while later we found the FMS to be defective (fms is fuel mgmt system) for some reason it dd not work like t was supposed to. but like i said boot can be good or VERY BAD for an engine...3-5 lbs on a stock engine might be ok, but the pressure can blow out every engine gasket you have if they have weak points.

EDIT: but when he hit the gas at 60 mph the car did go sideways (of course after a one month break in period)

hksfd3s:

1: did you swap an sr20 into the 240sx?

2: how the fudge did you come up with your username?

 

[hksfd3s]

I did a S13 Black Top (94+ motor) in to a US 91 240sx aka S13 body.

Mods on that one were.

HKS FMIC
HKS IR Spark Plugs
HKS Power Flow
HKS BOV kit
HKS EVC IV Boost Controller
HKS Down Pipe
HKS Dual Dragger Exhaust
HKS Gauges
HKS Wastegate Upgrade
HKS Fuel Pressure Reg
HKS...pretty much everything they make.

HKSFD3S-

HKS- Was my Primary sponsor when I used to compete

FD3S- Chassie code for a 3rd gen 93+ Mazda Rx-7

Before it was stolen my car was the only street driven Rx-7 sponsored by HKS USA. Used to compete in shows all the usual stuff. Magazines. It was the white Rx-7 in the first Fast and the Furious if that helps any.

 

[izackary]

i might have heard of that movie...heard mixed reviews though...

have you ever heard of 'Project 240 SS?"

 

[hksfd3s]

Yea movie was crap...

Actually are you talking about Super Street's 240sx? I've been out of it for about a year or so now though.

 

[izackary]

naw, it was 240 SS as in Chevy SS. I was looking around on things while i had my mom's (formerly my younger brother's) black '93 240 coupe. What it was, was a 240 SX with a Chevy LT1 in place of the stock motor. I chatted with the guy; he said he had over $10g invested in motor mods alone. It wasn't a stock LT1, though, but it was pushing about 350 hp i think. I believe doing that also requires a complete suspension overhaul due to the vastly increased weight in the engine compartment.

If you want a turbo in your x to make it faster and to do it cheap you must first sell your x and buy a car that has a turbo in it. If you want a fast car, buy a fast car because the x just isnt. Plus it's not worth dumping the money into to make it truely fast. What's fun about the x is making it perform better and handle better than it's supposed to but at a point you have to limit yourself. The x is still an SUV, cars are designed to go faster and handle better. If you're an engineer go ahead and re-engineer the x to handle like a car, but it'll take an assload of effort.
Plus I'm not all that responsible, I drive like an a$$hole For my own safety and the safty of the public at large it is better for me to have a car that's limited at 100mph and doesn't put out 200+hp. It's still fun to drive but it limits the ammount of trouble I can get into. I'm resposible enough to know I'm not resposible enough to own a fast car.

everyone so far has skiped over compression ratio when running boost. The lower comp the more boost you can run. Anytime going for boost the safe way is to drop the compression. I blew up my supra once due to just 12 psi on a stock engine (just over 6 psi stock) oops, shouldnt have done that. then I went 8.0 :1 and ran double that reliably till I got rear ended by a rice boy

 

[evilX]

If you want to turbo your X, go buy an Eagle Talon TSI or Eclipse GSX. 210 hp, all wheel drive. You can still drive through 2 feet of snow with it and put a hurtin on stangs while your at it .

 

[TheRookie]

heh, put a hurtin on them after some mods maybe

I'm guessing that it wasn't a 2JZ then. But that is true. With most turbo cars you'll find an 8:1 compression.

Mitsu are good cars just BAD transmissions. You can modify and get really good power from them just don't plan on your transmission lasting.

Turbo's do rock!

I had a '90 LX convertible mustang with the 4 cylinder in it. Snatched a Turbo form a old turbo thunderbird bolted it up, put in new injectors. I used to love the look on the guys in GT's and Camoro's when I would burn their ass. The biggest thing with turbos and supercharges is getting enough gas to the engine. You need like 75lbs-90lbs injectors. a bigger throttle body would not hurt either. You have to pipe in oil and water to feed and return from the turbo. THen the fun part of finding a shop that can do custom pipe work for the exhaust. It could be fun if you had the, time patience and cash. No more thatn 9:1 compression. Man i could go on and on. Get a superchrger and be done with it. BTW you can get appx 1-1.5 horsepower per cubic inch with forced induction on a stock engine!

 

[Alec]

Those injectors are huge for anything other than a fairly modded 4 cylinder or very high power drag car. Our Explorers come stock with 19# injectors, and the max most forced induction Explorers would need to go would be 24 or 30#.

 

[typhoon43]

yeah I was about to say those injectors would FLOOD an engine
I ran 21 pounds on a TE-60 (900 CFM) in my Typhoon all the time at the track with stock 33# injectors and my O2 voltage stayed pretty damn close to stoich (.925mv). It was only a 4.3L 6.

 

[gixernut]

hi
there is no difference between a super charger or turbos as far as engine reliability and compresion ratio
go . the term slap a blower on and be done with it is crap
the only probs i can see with fitting turbos to a X would be lack of space in the engine bay but it could be done and safely
i have done two totally hand made turbo conversions at home and i aint no mechanic ,one running stock compression ratios with no probs at all running 10 psi boost
as you guys say in these threads is its all about planning
matching turbos isint that much of a black art either unless you are trying to get the maximum amount of power out of the given engine, but for a good power upgrade you can get away with quite a lot

[Alec]

I disagree. Different types of superchargers and turbos create different amounts of heat. And obviously different intercoolers and aftercoolers (or none) will help reduce that by varying amounts. So no, you can't say that "X" lbs of boost is always the same.

 

[hksfd3s]

There is a big difference in the amount of heat produced by a turbo and a supercharger. Also sizing does matter.

25psi is not 25psi. You have to consider cfm as well. Put it this way. A stock mitsubishi eclipse tend to run high boost. Somewhere close to 15 psi stock. So you're saying if I slapped on something like a T04s or a 20G and ran the same amount of boost I would get the same rwhp as the stock turbo? No.

Put it this way. If you were to get a blowdrier and a housefan blowing air at the same psi. Which one do think would move MORE air in the same duration of time? The larger fan would. It's about the volume of air just as much as it is the pressure.

A larger turbo does not have to work as hard to move as much air but you will have a lot more lag and less response time getting that thing going. Just as smaller turbos spin faster and have better responce they tend to top out on the highend when they have reach the limit they can spin safely.
