how many of you have done the NA to TII conversion? (NOT THE SWAP!)
 

Using the stock TII turbo, exhaust manifold, intakes, ECU:

^^ I found that in the FAQs^^

im about to pick the route in which my NA will become a TII... and was trying to figure out how i can learn the most out of it.
i chose to buy an NA so i could learn everything i could by building it into a TII

so i thought that maybe instead of doing it the "easy way"(which im sure for some wasn't really that easy) i could possibly learn more by doing the conversion

has anyone else chose to do it this way?
and how did it turn out?

"learn everything you could" sounds alot like "spend as much money as possible"

Hopefully you got a GXL or something with upgraded brakes and the LSD, at least.


Anyways, do all your reading on http://www.aaroncake.net . He documents the swap wonderfully. It's a lot more headaches than it's worth.

If you want to learn a lot, drive the car as it is right now. Read read read read read. Buy a blown turbo block and rebuild it. Build your own manifold. Buy a standalone. When you're confident, you can then swap everything in, minimizing downtime on your car and learning much more than just swapping a stock turbo/manifold onto your N/A block.

alot of people turbo their n/a on this forum.

Im in the process of doing one right now. At most, you're spending atleast 700-900 for the entire thing. Though its mostly stock items though.
Turbo manifold
Turbo itself
Tubo intake manifold (entire assembly including TB)
stock turbo intake tubing
stock intercooler
Turbo ecu
Turbo MAF
Turbo fuel rails
Turbo injectors
turbo boost sensor
Better fuel pump
oil and coolant lines

I might beforgetting some little things but this is basically what you need


Also you are going to need a clutch that can handle the extra torque.

That's actually not true. I don't document swapping the TII stuff onto the NA engine. My writeup covers using as many of the NA parts as possible and making a true "turbo NA" setup. Swapping the intake manifolds from the TII on is dead simple and very inexpensive if you have easy access to the parts (which everyone here does via the classifieds). The only real fabrications necessary are to adjust the ports on the lower intake, figure out an oil feed and add an oil drain to the pan (or you can swap on the TII front cover). The rest is just bolt on stuff since outwardly, the engine becomes identical to the 13BT.

You can use the TII ECU and related stuff to make this fairly turn key and a weekend project.

Personally though, I figure if you are swapping on all the TII stuff, why not just put the whole TII engine in there? Unless your NA engine is very new or otherwise majorly modified...

Keep in mind also that my project is a bit atypical of most turbo-NA projects. :)

Yeah.
Yours works.

Bwhahahahaha!

what ARE the differnce between the NA 13b and the turbo 13b?

Just the compresion ratio? If so it seems that turboing the NA would not be that hard, just could not run as much boost?

It turned out just fine and I passed emissions testing two days ago with it. How many of these conversions can do that? Not many if any.

the n/a 13b also 6 intake ports as opposed to the turbo which has only 4 :icon_tup:

yeah i knew that lol. but other than that what other differnces are there?

exactly, i hear just to plug'em right???

NA front cover has no connection for turbo oil drain, and there is no oil feed connection coming off of the front iron. Drill your own holes and run some AN lines.

Besides the physical changes, running the stock TII ECU with a 9.4 or 9.7 compression ratio isn't the best idea. You should use at least an AFC to adjust the fuel map.

higer compression
6ports
different injector sizes
different ECU
no oil feed
no oil return
different clutch/flywheel
different intake manifolds


what did I miss?

Plug what? You make the turbo intake manifold ports match the six port na's intake gasket by using a rotory file and filling in the voids with moten metal. OR you can buy a intake manifold already machined from a site that has been mentioned on this site before. Sorry, that name is lost in my head somewhere.

And buy a RTEK2.1 if you have concerns about fuel/timing.

I didnt read the thread, but the hardest part of the whole thing was porting the LIM to match the 6 port block(see avatar) and then routing oil and coolant lines. neither was THAT hard. If you want the pre-made LIM Japan2la (I believe) was selling a very nice one. I would have bought his if I knew about it before making my own.
