HEY YALL!

Since im just getting into Forced Induction. Id figure you guys wouldnt have a problem answering a few questions for meh :)

Well first off, im aware of the circulation of a turbo and some of the pieces you need to handle one reliably. Im also aware that you need a tune to run a turbo.

I asked blue samurai a few questions about this and he helped me out but i never got in depth.

So heres my questions;

Is it absolutely necessary to purchase a new fuel pump when all your doing is adding a non ebay turbo and the things required for them such as injectors?

a follow up to the previous one, if you have a basically stock engine, what cc's are required to the max of the injector cc's needed? i was thinking of just getting 550's.

Why do you have to have a obd1 ecu to install a tune for a turbo?

When i asked blue samurai for some info he mentioned tuning programs and what am i aiming to turn my car into. What differs in each program? just the preference and quality? what do the programs contain? shit, what are they in general?

Why do you need a performance dizzy for boost?

Can you run a turbo untuned and on a unbuilt engine? even for just a few miles?

I'v read the turbo 101, the whats needed, etc etc...

I can only answer a couple as I don't know much about boost. You need obd1, because obd2 isn't tuneable. Just the way it is.

You don't need a performance dizzy

No, you should not run it untuned, even just for a little bit. At least get a basemap to get to a tuner if you can't trailer it.

why not? Your old one is probably bad and its cheap

Why do you have to have a obd1 ecu to install a tune for a turbo?
no apexi what ever can tune on OBD2 but hondata etc use obd1

When i asked blue samurai for some info he mentioned tuning programs and what am i aiming to turn my car into. What differs in each program? just the preference and quality? what do the programs contain? s***, what are they in general?
they redo the maps on your ecu and determine drivability vtec etc. Hondata is my personal preference and many will tell you crome is shit. not many people use neptune but its also good. Apexi is also good.

Why do you need a performance dizzy for boost?
you dont

Can you run a turbo untuned and on a unbuilt engine? even for just a few miles?
no yes. to a tow truck

also injector size is determined by hp. Roger uses 550 on his super charged gsr and that runs a 12.6 as you probably remember. it has less than 250whp. Stock 240 injectors max around 180whp 200whp requires a 328cc injector i believe

Exactly, so i figured just in case i go for higher hp i wanna get the 550 that stanardizes round 350 i think

If you plan to make over 200hp, then yes a fuel pump upgrade is needed. The stock pump isn't made to push a lot of power, and above 200hp is generally pushing the pump pretty hard. Walbro255's are only $80-90, so upgrading isn't bad anyways.

240cc/min (stock): 170-180whp
310cc/min: 200-240whp
370cc/min: 250-275whp
440cc/min: 300-325whp
550cc/min:350-375whp
650cc/min: 400-425whp
750cc/min: 450-475whp

There aren't many tuning options for OBD2. Most tuners just prefer you to convert.

You would really have to read up on them each specifically, but basically features is a huge deciding factor. Hondata is by far the best to tune our cars, and it's up among the more expensive ones. (Seeing as how some of them are free programs.) Hondata being about $500.

You don't need any ignition upgrades unless you're trying to make a ton of power. (I believe I read somewhere the stock ignition is good up to 500-600 hp?

Yes. I do not suggest it AT ALL. You can very easily melt a piston and blow up your motor if you're running un-tuned. But just for all those nay-sayers, a buddy of mine ran for months un-tuned with an eBay turbo and stock injectors. Was it a good idea? No. Did it make a lot of power? No. Did his motor blow up? Nope.

Hope that answers all of your questions.


EDIT:
Some of these were answered in the FAQ....

yes, fuel pump kits are $100, get one.

Your injector size should correspond with how much power you plan on making and what type of fuel youll be using. You should ideally keep your IDC under 80-85%

Why do you have to have a obd1 ecu to install a tune for a turbo?

most tuning software is made for obd1 ecu vehicles, and it has to do with the actual tuning itself iirc.

When i asked blue samurai for some info he mentioned tuning programs and what am i aiming to turn my car into. What differs in each program? just the preference and quality? what do the programs contain? s***, what are they in general?

each tuning software has its own perks and benefits. most importantly, you should find the tuning software your tuner is most comfortable using

Why do you need a performance dizzy for boost?

you dont

Can you run a turbo untuned and on a unbuilt engine? even for just a few miles?

you can but you cannot go into boost, or youll blow your engine to pieces

ok.. a question.

When i received my turbo in the mail. the face plate for the turbo inlet side was off and it has 6 open holes but no holes on the place it goes? did i not a receive a piece or is there some sort of trick im missing?

Looks exactly like this.
