Hey dudes..

I'm planning on turbocharging a D17A1 engine and I've gone through some speedbumps.. I've been told by some people that the ODB-II computer will not like the turbo and the check engine light may come on constantly as a result of adding a turbocharger.

What is the guaranteed way I can make a turbocharger with for my car. I will aquire a compressor (internal wastegate), intercooler, blowoff valve, and a bunch of plumbing from a source.. as I am not purchasing a package. (so I'm not buying a kit but I'm buying seperate parts from different places) I need to know now I can make sure this is successful.

Is there a company out there that reprograms my ECU to understand that there is nothing wrong with my engine and that there is added boost? Cuz I heard ODB-II will give me some problems.. because of the super tight emission standards in the D17A1.

I've been told that if I boost 6 or 7 PSI.. the check engine light should not come on.. unless I install it wrong or I boost over 10 psi. Is this true?

Should the D17A1 block be able to handle 6 or 7 PSI or should I have it sleeved to be certain?

Please help!

well on bmw's..you must convert to OBD1 due to that problem..as well as power, OBD1 will give you a nicer output with power...

if your refering to 9psi and over and the engine light..thats obvious, 9psi or more get a new fuel system.

Could I stay with ODB-II and have the stock fuel system to work with a low boost turbo? 6-7 psi...?
Or do I need a FMU or AFC hack?

the new honduhs have a returnless feul system so I'm nto sure how that woudl work I knwo that turboign the d17's is a biatch and only a few peopel in north america have doen it.....I have no idea what you coudl use for your feul system...might have to go haltech or somehting...

I've asked some people and they said that I can try the MAP Sensor Isolation Valve from companies like Synapse Engineering and that should allow for my check engine light to go off.. however the factory fuel system should allow up to 10 psi of boost.

Are you referring to one of these like in my thread with my turbo stuff for sale?

Yes. like that but mine's part ML0004 or something. for the D17.

take out the bulb >>> check engine light

guess what your "stock feul system" won't even to able to support 4 psi...let alone 10 psi on a decently sized turbo...... ...your probobly gonna need to get a standalone with injectors...I dont' think a vafc will work with the new motors

Kent, I've been helping my buddy do a turbo on his 2002 Si Veloz... still working on it. $10K in parts and labour so far... and still working out kinks. Greddy e-Manage solution, 450 cc injectors, custom rail, big pump... custom manifold. There is someone making a kit now, but it has the same problems my buddy's having.

the Veloz is a D17A2. My engine is a D17A1. It presents different problems. My cat is shoved up right against the exhaust manifold as opposed to the D17A2's which is under the car.

If I don't remember wrong.. DRAG, GReddy, and DiscountTurbos makes a kit for the D17A1 and D17A2.

I'm beginning to think that's it not worth it... I should be saving my money and using it for other things.

Not true, his was in the manifold too, he now has a custom one (Catco) under the car.

haltech woudl be your best bet...then no worries about fuel and ecu and map sensor....or igniton.....either way get an exhasut and intake then get a nx nitrious kit if you want some speed....then go suspension....tein possibly..??

running the VAFC hack u will require bigger injectors and fuel pump.... and I don't mean bigger in size .....lol I mean higher cc injectors and fuel pump
but the VAFC might not work on the D17..... not sure but the VAFC2 is out so u have to find out if u're going that route

....with just 6-7psi I think using a good FMU would be ok but now ur only problem is the timing..... since ur timing cannot be adjusted .... that I think u'll have to get something like the J&S safegaurd that does ignition timing retard /boost retard

NoSpleeny

Couldn't you drop in an adjustable AEM cam gear and retard the timing a bit?

ryuujin

that doesn't control ignition timing

so many people are trying to stick a turbo on this D17A engine but hardly anyone can really sucessfully pull it off

I hope someone does it soon, hell even my friend is trying to do one, he's got all the parts ready, but is missing the turbo manifold

NoSpleeny

Wouldn't buying a GReddy or DRAG kit make everything work successfully?

I've heard of successes on the 7th gen website for the Stanford Fabrication kit or something.

R0Y

well.... if the "kit" is made/designed for the 7th gen then it should work
maybe it's time to hit these guys up.... www.essentialspeed.com
they just did a custom turbo for my friend's P5...
and I must say they know they **** well... and does very good work.... well at least on my friend's car and the owner's welding skillz is

but dam they're far....
