T3 Turbo Swap Questions

Alright, I finally got my TC running right, now I am going to leave it like it is for a bit, probably over the summer, but towards the end I am possibly going to swap a T3 in there if I can find one. Couple of questions..

1) From reading other posts, it is my understanding, if I get the T3 from an SVO, it will be a direct bolt-on. Is this true?

2) let's say it's not from an SVO, but from an older TC or Merk. How hard is it to swap in?

3) I should have said this earlier. I have a completely stock 87 TC, and the engine has a little over 100K on it. How much can I benefit from the T3 if I leave everything stock?

4) The mods I would like to do is a K & N Cone filter, and a Ric Gillis Valve. If I can afford it I would like to redo the exhaust, but for now that is not a factor. With the above 2 mods (Cone and Gillis Valve) How much will I benefit from a T3?

5) What are the advantages with a T3 versus my stock IHI turbo?

Thanks!

1. It's a bolt on but you will have to get a T-3 oil return line, they are different from the IHI return lines. You will either need the SVO water supply line and return line or do a little fabrication. It can be done with regular fittings and some imagination.
2. If from an older TC or Merk you will either have to change the compressor housing in order to connect up to the intercooler or machine the flange off the original housing to get the hose on it.
3. The benefits will be in the mid and high range where the IHI runs out of steam. You may be able to run a couple more psi boost over the IHI.
4. The Gillis valve will allow full boost much lower in the rpm range, The K&N helps breathing, no matter what else you do. If your looking for specific numbers, nobody can give them to you, it's guesswork until you put it on a dyno.
5. The IHI offers quick spool up and good low end response. The T-3 can move more air at cooler charge air temperatures and achieve higher usuable boost levels. It's slightly slower spooling up but makes up for with a stronger top end
