Question Threadstone Turbo Kit (need your input)

I Need the combined knowledge of you forced induction fans.

I'm the owner of a 06 tc, and I have been wanting to boost for quite some time. I have an opportunity to buy a new Treadstone kit (previous model, before they bought the rights to turbonetics).
According to the seller, it was originally ordered for an automatic scion tc (same year as mine), however I plan to install it on a manual trans.
The kit is supposed to contain all original pieces with the exception of the AEM FIC.
I would like to have an experienced person look over the pictures below and making me aware if anything seems missing from the setup, or of what pieces you would recomend adding to this setup to make it more efficient, as well as what would necessary to set it up for installation on a 2006 Manual Trans TC. Pictures can be found below.

Here is what is supposed to be the original part list

Any help would be greatly appreciated.

Hello. From what I can see in the pictures here is a brief assessment.
1.) There is no engine management. You will need some sort of computer (AEM FI/C or EMS2) to get it up and running.

2.) I would also be a little bit concerned with the fuel injectors since they are just laying on the dirty floor. If you decided to buy this kit, I would have them cleaned and flowed as well to make sure what cc they are before you put them in the car. Last but not least these injectors are not plug and play and will require you to cut your factory fuel injector harness and splice these in. We can sell you new injectors that are plug and play if you're interested.

3.) I cannot be for sure, but the turbocharger or at least the exhaust housing looks a bit large. Do you have any specs?

4.) the intercooler will more than likely require you to cut the bumper reinforcement to make it fit behind your bumper.

5.) Cast exhaust manifold (a.k.a log manifold) have always been prone to overheating, and then cracking.

How much is the kit?

THe kit is fairly inexpensive (1k), which is why Im considering buying it as it leaves cash free for more important things (propper installation, addons etc) responses below.
1. I am fully prepared to purchase the recomended engine management for this setup, following your recomendations, which is the best with this setup. Ive read on this forum that this kit isnt liked by the greddy emanage. do you know of that?
2. I certainly will. I would honestly also preffer PnP injectors to avoid splicing. What size injectors would you recommend for this setup.
3. size, not quite sure, specs are located on my second link above.
4.Would a different intercooler avoid this, or would I also require different piping for changing the IC? Im fine with cutting. The pictures I have seen do not look extreme.
5. I was under the impression cast iron manifolds are usually pretty strong. Is this something I should be concerned about if im not looking to do world record type boosts? I plan to be running fairly low boost.

With the items listed, its definitely worth the 1,000. With another 500 you could be up and boosted. if you use those injectors, just make sure you solder the connections, and then shrink wrap around the connections. as far as fitment, i dont see an issue, but you may need to hack up your bumper. but i found it completely justified to cut my bumper for boost

The AEM FI/C is only about $300 but the part the plug and play harness is also required, which is going to run you another $279-$359 depending on the year of your tC. I don't like the e-manage either.

2. I certainly will. I would honestly also preffer PnP injectors to avoid splicing. What size injectors would you recommend for this setup.

We have the 750cc RC injectors available for $389, which will work perfect for you. The 550cc is the same price and also works, but if you ever want to turn the boost up you may run out of duty cycle. That said we always recommend the 750cc. The plug and play harness for the injectors is $79.95 and also available in our web store.

3. size, not quite sure, specs are located on my second link above.

Size is important. It doesn't give the specifics on the link so I would definitely get this information prior to purchase. It looks like a really big exhaust housing, which could lead to a very laggy setup and with that size intercooler it isn't going to help.


4.Would a different intercooler avoid this, or would I also require different piping for changing the IC? Im fine with cutting. The pictures I have seen do not look extreme.

It would definitely help you out, but if you go to a smaller intercooler it will more than likely require you to purchase new intercooler piping (or pay a fabrication shop to modify your existing piping. Cutting your factory supports will also cost you some $. You don't want to cut corners when turbocharging your car. I've never seen a happy customer that purchased a $1,000 turbo kit. Usually they end up spending as much or more than our bolt on & go kit in the long run. Just my opinion ;)

5. I was under the impression cast iron manifolds are usually pretty strong. Is this something I should be concerned about if im not looking to do world record type boosts? I plan to be running fairly low boost.
They are okay, but fatigue and crack over time. A stainless steel, equal length manifold is much better.
