N/A To Turbo Conversion

I know this has been covered and i've searched a bit, but i was wondering if someone could direct me to a detailed list of parts needed to effectively convert my N/A Motor to a turbo setup.

I have found good deals on Turbo Rotors and turbo kits and i was thinking of doing this instead of the TII swap b/c it would give me peace of mind knowing my motor has been recently rebuilt...

The swap isnt for the dumb.

Plenty of info available searching outside the faq too. Ask questions after a weeks worth of research.

I have been considering making such a kit. However, after weighing the expense of the parts and the time to build and tune the ecu as well as profit margin, if any. Not to mention the issues that arise if there is an issue either from a part failing, engine issues or installer/user mistakes that could result in warranty and/or liability issues that I'm not willing to deal with.

In the end i didn't have the ***** to put a huge investment into getting a kit together that, in the end, could cost me more than I could sell it for.

I could, if provoked, put together a kit but i would need to know A lot of info and it would end up being crazy expensive.

Also.. you dont need to change your rotors to turbo charge your 6 port. :-P

A kit would be pretty expensive. Sonicrat sold a kit for $1200 with no turbo or intercooler I think. I did my entire conversion for -$1000.

Read a book and educate yourself about turbos. Buy a cutting wheel, and a dremel, learn how to weld or find a machinist. Its not rocket science.

Nope, minus the tools (dremel, cutting wheel, hacksaw, wire cutters, wrenches etc.) it was all under $1000. I can break everything down for you if you'd like. It still doesn't have a wideband or an RTEK/ fuel controller but it runs pretty good on the stock ECU.

I may be wrong, but here is the list of parts I would say would be the minimum requirements for a "turbo kit"

Turbo
ECU
Injectors
Fuel pump
intercooler and piping
a crapload of braided line and fittings in 6an and 10an
wastegate
BOV
turbo header that locates the turbo in a "forward" position
compression elbow or nifty adapter to stock.
boost gauge
wideband O2
custom down pipe
a bucket of misc tools n hoses n stuff.

I probably forgot some things but thats what i got off the top of my head. I am also assuming use of an aftermarket turbo and not just robbing an old factory turbo setup off a parts car.

I hear there's a rumour that a well known member of this forum who has a turbo'ed NA will be making a total bolt on kit soon....but it's just a rumor...or is it?

I'd be down to purchase any kit someone put out. I've spent enough time and money on my car and would not want to do a motor swap again. I don't care what the cost is...someone give me a kit! My NA is 6 port but I removed the sleeves and such. I assume the actuators would be removed with the addition of a turbo anyway.

Will said kit be with tII parts or all aftermarket? I think you, er... this well known person should make a kit similar to my setup only using a full t4 and possibly a cast compression tube rather than the adapter to the stock n/a tube...

Removing the actuators is a hack and only done because it's often the easiest thing to do. One would assume that any high quality kit would not require aux port removal.

Full T4 is a bad choice for a bolt-on kit. All TII parts are old junk. That is all I'm going to say at this point.

I did everything but these.

Had a 3 foot 1/4" SS line made by a local plumbing shop with proper fittings, ordered 1/2" SS hose with no fittings for the drain (hose clamps). Roughly $50 for everything. Used fuel injection hose for coolant lines.
Used the stock wastegate
Stock manifold
I used the first section of the stock intake, it is strong enough to clamp a reducer on to. Bought a rubber one (3" to 2.5") from home depot.

The price can vary greatly when you start talking about aftermarket turbos. It can be from a BNR Stage 2 to a 62-1 w/ full EMS. Usually people that do the conversions are trying to work around buying a TII engine, the cost and complexity of the conversion with cheap stock parts seems to be overestimated.
