NA-T in TII car

Looking for a cheap fix while I find what engine setup I want in the near future. Can I put an NA block in my TII (basically an NA-T swap) and run the stock ecu or will I need something to adjust timing and have it safe for stock boost?

When I search "na-t" I get one page of people asking about an NA-T in their NA car. And when I use google, I get a bunch of domestic mopar ****.
Give me some terms to search and I'll search it, but the other words I use yield no useful results.

And ****, whenever I see a thread for an REW swap I still give tips even though my thread was lingering around, stop being a **** head

I wouldn't recommend using the stock TII ecu on that.

Not sure I get the logic here.
Is it really so trivial to pull the T2 engine, swap the intakes (and whatever mods that will entail) and front cover and reinstall it, then get it running?
Seems like if you're making a decision in the near future about the "real" engine, why not just do that and skip this intermediate step?

Also, what's happened to the T2 motor and why not get that running as your stopgap?

Blown rear rotor, and I have access to an NA block. And I like being out in the shop and I'm getting restless. I have pulled and installed my fair share of rotarys, could probably do it in an afternoon

Seems like I'm repeating my self but I'm already aware of how to turbo an NA. What I am concerned about is when I bolt on all the TII parts, will I need to alter my wiring or stock TII ecu to compensate for the high compression.
The only NA part will be the block, I will use all my stock TII parts, including the shell. This is not a stock NA car. It is a TII car with a blown TII motor which I want to replace with a NA block.

The only link useful that I havent read in the search function is that tweakgames has an NA-T in his TII car, but that thread was about alternator wiring.

That aside, I'm going to risk it, unless a better turbo block pops up.

It's exactly the same as doing a normal NA-T swap but you get to skip the wire harness modification. Is it a s4 or s5 NA block and are you running the s4 or s5 turbo control system? Would like to know what compression ratio and 'stock boost'.

There is nothing to 'alter' in the wiring or ecu to change timing. You could retard the CAS, but that will reduce timing all across the board. An SAFC works up to a point. I don't like them, but some say it works fine. To do it right, you'll need a rtek 2.x or a standalone and make a new timing map.

I've looked into it too and people's experience vary widely, some just dump fuel and run stock timing, others do fine on an SAFC and some people mysteriously start part-out threads just after they get everything going. YMMV.

To be safe I would recommend a Rtek 2.1 minimum.

Thanks, that's what I needed to know. If its the same as a regular NA-T setup then I should be good to go.

Still curious what series keg and turbo control system you are using. You will have a very small safety factor running a turbo on an S5 NA keg.

Stock ecu is fine for n/a-t. If you are running stock injectors and what not, do not run more then stock pressure 8psi. Obviously run 93.
It's really amazing how much these ecu's can handle.

93 octane and no smog... you guys have it easy

And S4 keg/S4 controls = best case scenario for keeping it together. Good luck.

hmm I was running na-t on a few different high mileage na engines back in 05-09, when I was running mine I had the rtek 1.7 , and I had an safc,and was adding fuel in places to keep it quite on the rich side. I also had a bnr stage 2 turbo full 3" ehxuast, running 10 psi most of the time.

I found the longevity of the motors I had a year+with a bad coolent seal!, 6 months, 3 months, 2 months.
I think something with timing control would of probably greatly improved reliability(rtek 2.1 minimum),

though with how high of mileage these motors were some well over 150K they were time bombs on there own.

if your going to try it anyway, id recommend at least running 9's in the leading plugs, and keep your boost low like off the wastegate 5-6 psi. you shouldn't have to modify any wiring if its a real t2, with t2 wiring harnesses. and if its one of those just get the car running u could just leave the waste gate arm off and drive around with almost no boost, to be the safest

I just haven't decided if I want to rebuild my 13bt, go v8, or 20b...I don't want to waste money on a project again if I wont be satisfied at the end.
I bought this shell because its near mint, low km's, and I just want a reliable, fast car for the nice weather. And this block I found is only $150, figured I could part it out if I decide not to turbo it.
