Parts Required for a Custom Turbo Kit, and a basic guide for building yourself a reliable boosted setup.

Things that I put a must beside is what you will need no matter what.

* Manifold, A MUST: Footprint must match turbo, or an adapter plate is needed. Stay away from straight log manifolds. The only log that works well with honda motors is the rev hard, SFP, and love fab mini me. The basic logs flow is terrible, and you will a see around a 50hp between that and a ram horn design.

Copy and paste this to see a difference between a log and a ram horn design.

* Turbo Trim Size- Larger the size the more lag you will get but more top end power is there. The smaller you go the quicker the spool and better mid range tourque but lacks top end power. I recommend larger turbos for FWD cars since smaller ones make so much mid range tourque it causes gobs of wheel spin. I would say you should talk to a turbo supply person that understands trims, wheel sizes, housing sizes etc so you get a turbo that you are looking for.

People have to understand that PSI means nothing, unless you are comparing it to the size of turbo being used.  A gt28 or a small t3 at say 7-10psi is not flowing the same CFM as say a gt35r or a big t4 at 7-10psi.  People think that 10psi is just 10psi,  but running a larger turbo will cause more wear on the motor.  IE it's all about the hp being produced.

One small thing to remember is the smaller the motor the less flow it has. IE a b16 running a t4, gt30r,t-66(Bigger turbos) and so on well have a hard time spooling them up. Probably hit full boost by just over 5200rpm where as on a H22 it will hit full boost by just 3800rpm. Now if you port you head that will help spool it up quicker as well as running a higher compression motor, these are reasons why you should talk to someone that knows compressor maps etc. MUST HAVE TURBO

*Downpipe- Will need a larger downpipe. I would say no less than 2.5 for a honda but bigger is better. I went 3" all the way back

*Exhaust- Again I would go with 3". You can do 2.5 but 3" works better, trust me.

*Flanges- You will need all new gaskets and flanges for you exhaust system.

* Oil Lines Braided Stainless Steel ONLY. Dont cheap out..you could end up with a fire! MUST HAVE NEW OIL LINES

* Wastegate - Internal or External? Heres a basic guide for helping you pick a wastegate. MUST HAVE WASTEGATE
1.Big turbo / Low boost = BIGGER WASTEGATE
2.Big turbo / High boost = SMALLER WASTEGATE
3.Small turbo / High boost = SMALLER WASTEGATE
4.Small turbo / Low boost = BIGGER WASTEGATE

* Intercooler - Dual-side inlet/outlet, water cooled, air cooled? Size does matter here, dont go with a side mount they are not worth. MUST HAVE

* Intercooler Piping - size, bends. I would go with at least 2.5 for most setups looking for over 300whp. MUST HAVE

* Charge Pipe with BOV Flange - BOV Flange can be purchased at most online stores or comes with your BOV MUST HAVE

* Blow off Valve - HKS, Greddy, Blitz, Apexi, etc. MUST HAVE

* Performance Clutch and Flywheel - What stage, What weight flywheel? I would go with stage 3 and flywheel is really up to you. Lighter with a lot of power can sometimes break. Definatly recommened.

* Spark Plugs - Lower tempeture spark plugs help reduce detonation. Recommend but I say its a must

* Fuel Injectors - To flow more fuel into the cylinders. I wouldnt run anything less than a 450 if your trying for around 280hp. But I would say to go no less than 550 to be on the safe side. I am running 780cc with no problems and I still get great gas mielage. Size is the decision, but you will need to upgrade them.

* Internals - Pistons, Rods, and Sleeves Recommended if running High Boost. Will help keep your motor intact.

* Head work - This isnt required but I recommend it. I am running a stock head just cleaned up with new valve seals etc, but thats because the H22 head is good for up 500hp and flows like a champ.

* Intake manifold/TB - Recommended as well. Will add better response and much more power.

Now for the Electronics:
* Boost Controller- Helps elimanate boost spike, and maintain a steady boost level. Not required, wastegate spring can regulate

* Map sensor- Honda motors need a new map sensor if your going over 11psi. The stock one doesnt hold it. I would recommend you get a GM 3 bar map sensor.

* Turbo Timer- To further cool your oil after your car is shut off. Not required, more of a luxury.

* Computer. Crome, neptune, hondata, aem ems are the programs you can tune with. AEM being the best but most expensive and hondata right behind it. You can tune boost per gear with these, as well as a true two step. MUST HAVE, MUST HAVE, MUST HAVE lol. You have to use one of these for tuning if you want your motor to last.

* Gauges - Boost, Air Fuel, Fuel Pressure, Oil Pressure, and egt are recomneded.

Others:
*Fuel pump - A MUST
*Fuel pressure regulator - set proper fuel pressure
*Fuel pressure guage - in order to monitor proper fuel pressure
*Performance radiator - help keep everything cooler, recommended
*Intercooler couplers - to make sure your intercooler pipeing doesnt blow off. MUST

* TUNE, TUNE, TUNE -Dyno tuning is a very important step in the turbo process. It ensures that your A/F ratio is where it should be and that your motor is not running too rich/lean, that your ignition and timing is setup great as well. This is really the key to your power and to making sure you dont blow your car up.

Well I hope this helped you out if you are looking into boosting your honda. I honestly might have left a couple small things out because there is just so much to be done, and this shows you how expensive it can get. Turbocharging a car is something that should be never cheaped out, and I really think if you cant afford it, well dont do it. And stay away from ebay parts. 95% of them are garbage. The wastegates diaphrams and the bov's all leak boost. The turbos smoke like crazy after a couple weeks and they are really not setup for a certain engine. I highly recommend you talk to a well known shop in your area that deals with boosted setups on a regular basis.

GOOD LUCK ON YOUR SETUP. IF YOU HAVE ANY QUESTIONS FEEL FREE TO ASK.
