I know this is probably a Re accruing post. But the internet sucks where I'm at so Im about to just post it up.

I was looking for any non bi-est opinion on a turbo 8 to a supercharged 8. Im Deployed and when i return from overseas I plan on purchasing one or the other. Any help would be nice

 

Start with FI for Dummies thread - it is a sticky in this forum.

Then get some reading material via Amazon, I know you have a bit of downtime, so educate yourself and then start shopping.

 

There is no better....Your gonna have to do research on your own and figure out which one will work best for you and your style of driving. Each has their own benefits and faults, and then even vary from kit to kit

 

Because it is a Sunday and I know how bad the internet is over there.

Start there.

 

Also asking for a non-biased opinion on this is like asking for only people with no heads to respond. Everyone has an opinion on this issue, even (especially) people who have no idea what they are talking about. Do the research, read up on it and make your own judgement on what is right for you. Going FI with this car is not a minor undertaking, so knowledge is important.

 

yeah alot of people are emotional about their lil cars.. i can get you an unbiased opinion, based on what you want out of the car

how much power you want?

how much do you want to spend?

what kind of engine management you want?? if that even matters.

Let us know what you want out of forced induction and someone can help you

 

Perhaps if you define what charateristics you are looking for ....
Just off the top of my head and talking generally

Power :Turbo>SC
Torque :Turbo>SC
Reliability :SC>Turbo (due mainly to the two points above)
Cost :Turbo=SC
Ease of fitting tuning etc SC>Turbo (in general)

 

All of these opinions also leave out the kit engineering and construction...

RIGHT NOW; with what is on the market - IMHO you cannot get a good turbo kit that will bolt on and work out of the box; and for some people that is an important consideration.

 

Odds are, you are going to purchase a kit. That kit will be made by a company. It will have X price, make Y power, and have a quality/completeness level of Z. Make a list of the kits with their X values, their Y ranges, and a general Z value. Then decide which one you want. There are not many good kits to choose from. I think at this point, the availability and quality of the kit trump whether it is a S/C or a T/C. Unless you have specific characteristics you want (and you don't or you wouldn't have asked), what you really what is a solid kit that makes good power.

I went T/C. Had I gone with a S/C that produced even ball park similar performance, I'm pretty sure I would still be thrilled. Yes there are differences but I don't think they trump the XYZ approach.

 

I'm looking for something that can still be a somewhat daily driver. Also there Isn't much for highways where I live so its mainly city driving. Looking to spend 5-6K on the kit.

 

That is true, the issue with that is there aren't really SC options right now that work out of the box either because last I heard the Pettit guys weren't selling their kit anymore. If they are still selling that kit, its a good deal because the construction is good and a good number of folks are using it. Also it uses an OEM ECU flash which is > than piggyback/interceptor options.

The Hymee kit looks pretty, but until even one person actually has it installed I wouldn't even consider it an actual option. Obviously the kit engineering is lovely though.

For ~300 whp I think the best option for cost effectiveness and reliability for the car is getting a used GReddy kit, making the needed changes and shipping the GReddy turbo off to BNR for the upgrade.

 

I concur (but I THINK Pettit is still selling kits, and Hymee's should be very user friendly); but as for a true good quality close to BOLT up I would go so far as to say; new Greddy kit, turbo sent to BNR, Cobb or Hymee Protuner, and an AEM Intake.

And after all of that you still have to tune the silly thing. So not exactly a bolt on kit...

And leave the boost PSI alone - once you wanna run a BC, then you fall into ignition, injectors, fuel pump etc issues.... A $300 EBC may be the most expensive single mod you will ever purchase.

Superchargers avoid a lot of that for those who do not like to tinker.

 

Except the tuning.
And the bypass valve.
And the idler/tensioner.
etc.

The absolute stock GReddy kit is the only "bolt-on" kit for this car.
If you install it exactly as it ships, it will work correctly right out of the box.

I do not know a single individual that will be satisfied by how that feels.

 

There in lies the rub...at the end of the day - we all think 240-250WHP is awesome (and it is); but then we get greedy.

 

Aside: Did they add the oil restrictor to the Greddy kit?

 

I agree with Jeff on this one. The only thing that is "simpler" about the supercharger is the inability to change your boost setting without changing a mechanical component. That does not make the supercharger simpler than a turbo setup without an EBC.

Can EBCs get people into trouble? Absofreakinlutely. That doesn't mean superchargers are simpler and it drives me crazy to continue to hear that said when it just isn't true.

 

It is not that they are simple by any means; as a matter of fact as a compressor they are not as good for our engines as a turbo - I am speaking to the kits that are available currently.

Having eaten a Greddy turbo from the out of the box kit in 3000 miles (with just factory boost EMU etc.... I wouldn't exactly call the Greddy kit a good out of the box solution.

 

The old adage again:

Cheap - Fast - Reliable
Pick two.

I suppose you could swap "Cheap" for "simple" in most cases.

 

Clarity and choice of terms / words can do wonders to any discussion.... 90%+ of the FI debates I watch are driven by people using wrong terminology or vague statements which are interpreted differently by other people.

FI is complicated enough, in any form, that clarity and detail is required for every step, including the research step, and it just doesn't happen normally.




(smiling from the sidelines because I don't have FI...)

 

!! PLUS ONE BILLION !!

I know I'm a bit of a grammar and logic ****, but most of the "discussions" on this board drive me absolutely insane. The use of mixed terminology, improperly applied concepts, logical fallacies, interjected emotional pleas and just plain, dumb parroting of "experts" has made it impossible for anyone - experienced or otherwise - to engage in a useful dialog about anything on this topic.

 

How did this turn into an English discussion? HAHA

 

A schooner is a sailboat, dummyhead!

 

You know what? There is NO Easter Bunny! Over there, that's just a guy in a suit!

 

WHAT?!?! but...but who leaves me all that candy?!

 

This guy...
