Turbo lsVTEC

[93ex]

I dont know too much in the way of turbos what would you reccommend? It has to be street legal and will be daily driven as well. Thanks!

[93ex]

Also is nitrous a good idea to accompany a turbo or will I end up blowing a cylinder wall?

Your lack of Knowledge Scares me. I recommend going to Barnes and Nobles or Borders and picking up that book on Honda Performance. Get it and read it. You will LEARN ALOT. Its not as easy as you think. I wont even discuss the amount of money needed either (you seem to think you have a bottomless wallet I know I dont).

To answer your question in the best way possible I reccomend going with a kit. It will have alot of what you will need and should install somewhat easily (not always true though). Most common kits are RevHard FMax Greddy and Drag. I prefer Drag. The HP #s that the Drag kit has given me are Phenominal.

So now the question is which kit for the LS/VTEC. That usually depends on the head intake manifold and Throttle Body.

I.E.=
LS(b18b)Block with SI(B16a) head= Si kit
LS(b18b)Block with GSR(B18C1) head= GSR kit
LS(b18b)Block with ITR(B18C5) head= Si Kit

Does this answer your questions?

BTW= Get the books. They only cost about $20 each and are worth it.

Ive done a bit more research an am coming to a few conclusions. Please correct me if Im wrong:
1)Turbonetics makes the best turbos
2)I need a T3/T4 setup
3)GReddy Profec series are the best electronic boost controllers.
4)XS engineering makes the best Intercoolers
5)MSD is the way to go for ignition
6)GReddy Type C and Tial make the best wastegates
7)I need >500cc injectors
8)ACT clutches are top-notch
9)JE 9.0:1 pistons are the way to go
10)Liquid-air intercoolers work the best

Is a Fluidyne radiator worth it? Do I need a liquid-air square intercooler or should I be ok with a regular intercooler? Who sleeves cylinders? Which is the best intake manifold: Stock Stock P&P Venom Skunk2 other? Are cam gears all the same? What is the phone number for South Florida Turbos? What is a good LSD? Turbo mainfold? Will stock rods hold up? Is a P&P head worth the extra $$ for turbo? Are there any down falls to ball berring turbos? Thanks for the help.

Who makes the ecu with the 2 stage rev limiter???

Do I need a liquid-air square intercooler or should I be ok with a regular intercooler? You should be fine with the regular intercooler
Who sleeves cylinders? Bensons Leitner & Bush www.leitnerbush.com and others that offer Dart and Godzilla Sleeves.
Which is the best intake manifold: Stock Stock P&P Venom Skunk2 other? Probably Skunk2 or Venom
Are cam gears all the same? No Quality is the Difference. For that kind of power stick to JUN or HKS
What is the phone number for South Florida Turbos? Who? Do you mean Southern Florida Performance
What is a good LSD? Quaiffe or Kaaz (Dont get Phantom...it sucks)
Turbo mainfold? I like the Drag Gen III manifold
Will stock rods hold up? I wouldnt go above 15psi on Stock Rods or 13 on Stock pistons (This assumes the car is WELL tuneD)
Is a P&P head worth the extra $$ for turbo? Depends on where you get it done and for how much. Dwans in Clearwater charges $500. Eyndyn charges $1200. How fast do you want to go and how deep are your pockets?
Are there any down falls to ball berring turbos? Most Ball Bearing turbos that you will come across are not Full BB Turbos. Full BB turbos have Bearings on both sides what is most commonly purchased is Turbos with BB on 1 side (I think it is Exhuast side). Disadvantage? I heard they leak oil sometimes (past the seals)

Thanks for the help.

Someone actually wrote a book on Honda Performance. Damn. That is one thing Hondas have over DSMs. No books for us just trial and error.

[emodsm]

the book is really good too..it has performance theriys out side of honda applications too I havnt read it but jerry has talked about this book before and says its awsome!

As always Maximum boost by Corky bell is a good book to rear if you are new to turbocharged applications.

Id agree reading it right now :D

Im still trying to understand these compressor maps A/R ratios etc. Thus far Im lost :confused:

[TealTalon]

Well Ill explain the little bit I know.
http://web.tampabay.rr.com/7seconds/50trim.gif

Lets take my compressor wheel for example. :D

The number on the left hand side of the chart is Boost+ atmosphere divided by atmosphere.

Atmosphere=14.7? well 14.something cloes enough. ;)

Say 14.7+18PSI/14.7=2.22 Thats the number on the left for desired boost. Now draw a straight line across to see where it lays in the map. The REALLLY large number is the RPM of the wheel. & is the % efficient at that RPM. Bottom is #s per minute of air it will flow.

So at 18PSI flowing 35#s per minute its still 78% efficient. That is great!

Now up to 25PSI =2.7 We are getting into some real power. 42 #s a minute.

#s a minute * 10 = aprox HP output potential. 40#s a minute aprox 400HP capable. :D

This shows why a car with a huge turbo running 5PSI still isnt going to make THAT much more power. You gotta turn it up to get the shaft a spinning and making power.

76% efficiency islands are still GREAT! Just recently (last few years) have wheels been made that are more than 75-76% efficient.

So ragged edge of efficiency...the far right hand side of the map. My Compressor is capable of 45-460? HP. That doesnt take anything else into consideration though. You still have EVERYTHING else to think of. If the head can flow it. If the exhaust can get that sort of pressure out of your car fast enough and on and on and on.




If any of that makes sense...or is even close to corect...someone give me a cookie. ;)

[Charles]

That helped I think part of my problem was trying to match up a pressure ratio and air flow rate that didnt fall directly on the border of one of the islands. This was confusing me so basically if the pressure ratio and air flow rate intersect inside of one of the islands than that level of efficiency would apply for the entire interior of that island(give or take 1-2%) ??

Now Im just trying to find a site to convert airflow lb/min to cfm.
