Mods for TII w/ a T4 turbo?

[Whizbang]

so i am pretty certain i would like to go down the road of a T4 turbo on my Turbo II. Cast iron HKS or Greddy manifold about a 1.00 hotside with nothing too outrageous compressor wise.

Not for control this bastard, what should i look into control wise? Obviously getting something like a standalone is a good bet, is there any other options? Like the Rtek 2.xx? How about used standalones?

Power level wise, id be happy with 300 (at 6,000ft elev.).

Rtek. Cheap, plug and play, and adjustable! Now available for both S4 and S5.

I've had piggy-backs (SAFC AND AVCR) and now have a Haltech (not installed yet so i don't know much). Classic had a HAltech and moved on to a "better" ECU.

I like to buy used but it's a risk you run. Example, I haven't installed the Haltech yet so I don't know if it will work or not.

Well, the clear choice for management is a standalone. Rtek's are capable units but you're still dealing with a 20 year old engine harness. If yours works fine, then hey go ahead and use the R-tek.....if it were me though I'd much prefer a fresh harness and absolute *FULL* tuning capablity. There's alot of used EMS' out there that aren't that spendy but beware when you're buying used you're not going to get a whole whack of support if the unit is DOA or has issues, so make sure its a good unit if you go that route.

Its really what you feel comfortable with and or what your tuner prefers.

hey, what ECU did you buy. All I know is that it's better but can't remember the name.

thing is i doubt there will be ANY tuners. I know i can get a base map to get the car running, but i am worried about all the "other" crap involved with a standalone and getting it to run right.

Obviously there are similiar things for the Rtek so you know what your engine is doing for tuning.

The other option i could pursue (because i am one of those DIY'ers) is get a FC turbo harness. Determine the wires needed to be removed, removed them, then rewire the harness with fresh wires. Not too hard with the right tools, just needs to be done in an organized manner.

Phoenix - I went (or am currently installing...) Electromotive TECgt :)

Just FYI, Haltech is easy to find base maps for nearly anything. Microtech, no since you can't save you map it has to be built from the ground up after an install. Electromotive, you can save maps but not alot of guys (around here anyway...) run them on 13B's so you've gotta have some background. Basically what I'm saying is Haltech is the best bet for a DIY'er who's not too familiar with EMS' since you'll be able to download a map, start the car and drive it around.

The "other" stuff you're talking about I'm not familiar with, please elaborate.

This is entirely plausible and easily doable on a clean bench. However IMO, for the effort and time you're going to spend re-wiring the stock harness for a computer with limited tunability, you may as well install a standalone since that harness will be less work (only terminating it) and you'll have much more capability after its done. But again, thats just me.

that and the fact that a new TII harness and wiring is about 800 bux.

i would MAKE the tii harness out of an old one in effect, but ill have to see what the haltech brings about. Im not going "balls out" so it may suite my needs.

Also, the "other stuff" would be maps, widebands, exhaust temp gauges, etc to have some feedback to tune by.
