Most turbo engines aren't designed for mid range...........
Generally speaking,
Low-Mid= Blower
Top end= Turbo
;)
No,
You can have a low end range with the correctly chosen turbo (of course its never going to be instant) as it is the same with mid-end etc. It all depends on what the car is going to be used for.
atm turbo kit isnt on....
got a mircotech with a tdo5
dont know about cams wat to go for...dont know size of injectors...was hoping someone with a b16a turbo will reply
wat power r u aiming for???...HKS gtrs r great turbos to run....not laggy and make good power..
hoping to pull something between 150 - 180kws at the wheels
i wanna pull a 12 down the 1/4 mile... but every day use
Your power/quater mile goals are easily acheived with the stock engine internals, decent turbo setup and minor weight reduction.Quote:

Good luck on your 12 sec pass it's not as easy as you think. Anyways if you're building a b16 for turbo it's not really the head you have to conentrate on. Bottom end is where it's at for boost.
Like fishman said, it's not really the head that you are looking at when boosting. Sure, ported polished etc will always make you extra power, but it's really money you don't need to spend.
The best set of cams you can buy for a B16A with boost is ITR cams (I actually have set from when I was going to boost my B16 - PM me if you're interested). I did extensive research and even spoke to some US guys to find this out and 8/10 of them all said the same thing - ITR cams.
didnt think a 12sec pass would be easy in a honda.....
but still hoping to rip out a 12sec pass after the turbo kit is on
where do i start with the bottom end?
decomp?
bore?
shit theres heaps of things to do
and also does anyone know wat size cooler fits onto a EG without cutting the radiator support?
The 12 second club is a very respected one, good luck in your endeavours.Quote:

Yes you will need to decomp if you intend to run high boost - this depends on what your goals are. Things you can do to start are forged pistons, forged conrods and rod bolts. This should support your 180kw atw goal.
If you intend to boost more in the future, you may want to look at a strengthened crank and sleeves. Bore is not really necessary as boost makes up for any lack of displacement you may have - but if you got the dosh, why not?
It depends on how hardcore you wanna go man. Bare in mind that any FI build on a Honda is gunna mean cash money. You got the engine, which includes what I listed above, plus depending on how much boost you wanna run, you will need uprated valve springs, retainers and valves. Cams will net you more power so those will need cam gears as well.
To do it properly you will need an intake manifold as well as a decent turbo manifold (equal length for best effect). Then you'll need injectors, Fuel Pressure Regulator, Fuel Pump, possibly a fuel rail, you'll also want to replace your water pump and buy a stronger timing belt and buy some head bolts too. Then you need an ECU and a tune.
When I worked out what my turbo build was going to cost me to do it my way, it was going to end up at around $19k. Obviously what I'm talking about is an all out build and it depends on how far you want to go. You can turbo a car for around $8k if you piece it all together yourself.
Just a heads up man, cos you seem a little bit green with Hondas (no offence, just an observation). Modding isn't cheap bro! :honda:
If you got any other question man I'll help where I can, I've done my research.
if u dont mind running slicks, a 12 isnt too hard, we have a stock ek4 with 7psi of boost bolt on turbo kit running 12.7 and only springs modified
^ Yeah slicks will most definately help :)
Nice time btw. :thumbsup:
The problem with the internet is there is too much information around and people waste money on there basic setups.With your power goals leave the engine alone and just work on the turbo setup a B16A will handle alot of power before you need to start replacing internals inc cams.There is a B16A powered Gen2 CRX here in sydney that is fitted with aftermarket rods and pistons and has now run 10.5@130+mph using STD head and cams fitted with good valve springs and retainers I think this really shows what can be done using your brain and not your wallet or the internet guru's.Quote:

No I am not have a dig at you at all I know you did alot of research and thats great but the Yanks are full of themselfs and the internet makes it even worse so just be careful in the info you read and get.Quote:

Very true Dave, so what I said should be taken with a grain of salt really. Like I said WNARUN, Dave is your man. He's got a lot more hands on experience than most on.... the internet actually LOL.
No what you said is correct if you want an engine that will live forever at 30psi of boost and you have the money now to do it but at the level he is talking about you could do it for alot less with no problems at all using STD parts thats all keep up the research its good to see.Quote:

Yeah it all has to do with americans influience IMO. I remember the days when you used to just buy a bolt on AVO kit and be done with it. Easily enough power to pull 12 s. But these days everyone seems to be so eager to get on it and pull down what is already a decently engineered honda powerplant, to replace every part with a forged or modified item.
Sure there are parts out there that perform better that the stock honda ones but dont be wasting bucket loads of cash just because that ramhorn looks better than the ductile cast iron manifold for a quarter of the price, when there is really no need.
Keep the motor dead stock, add a bolt on kit, tune for anywhere up to 10 lbs, slicks, = 12's easy. Thats w a b16, and similar results can be had with D16 enignes as well.
Photonic.
I have gone down the Avo route with my Crx see here:

And while yes they are very good kits with great results, but to keep the price down the individual components are a cheaper option, and will not let you expand if you build your motor further down the track.
The truth is that an individual can purchase thier 'own' turbo parts which are of much higher quality for a very simular price as complete Avo setup. With my new setup I am probably going to spend just a little over what I did with the Avo setup, but I will have an quality setup that is excellent for stock internals and will let me expand down in the future if I decide to.
Well yes. i agree with you. There isnt much scope for upgrade with an AVO kit. For someone who has little or no knowledge of hondas or any car for that matter, AVO do good work. You can piece a much better kit together using parts from better companies, but that wasnt the point i was making.\
Too much enpahsys is made on having a "fulley forgd, max-d owt, turboez" engine when the truth is, in the search for reliability it all comes down to the quality of the external components and tune applied.
My point was, dont over look the value of a "bolt on" turbo kit (whether it be AVO or your own) as a reliable means of REAL power, and dont be sucked in by the big flasy neon signs of every American aftermarket Honda parts manafacturer, because chances are, you dont really need the 'FULL HOUSE' set up they are peddling to get the result you desire.
Yes, I agree with too you mate. I spose depends what your after, needs, wants and personal experience.
In the end it comes down to the 'individual'. To do their own research and discover what the best option is for them. To disregard all the Hype and Advertising we might see. :D
