Turbo recommendations

[kevmarf]

I am adding turbo to my 94 Ranger 2.3. Right now I have turbo and manifold and computer(no harness) from 88 TC. I have fuel pressure regulator and 38mm BOV. I have ordered an intercooler as well. It sits now with a port/polished head(dual plug). Stock long block. 3 inch downpipe. 3.73 trac-loc rear (7.5). I also have green injectors if I need them. This will be a daily driver. Not looking for more than 10 psi, not racing, just better performance and appearance. I plan on starting install next weekend. Any recommendations for my setup?

if you have the turbo off of the TC, that should be plenty to get you ~10psi, and should be plenty small to get quick respnse, but this should really be in the forced induction section...

I would highly recommend using the fuel injection system from the 88 TC (which uses 35 lb/hr brown top injectors) if you can get it. I'm pretty sure green tops are 42 lb/hr injectors, which were never used in any turbo 2.3 application by ford. The 42's should work OK with an EEC setup for 35s (like the one out of the 88 TC) if you get an adjustable fuel pressure regulator and turn it down from stock pressure a little bit.

In any case the stock ranger 14 lb/hr injectors are not going to support any amount of boost at all and 10 PSI will make it run so lean that you'll melt a piston/valve etc in very short order.

You shouldn't need the wiring harness. The ranger 2.3 harness is so similar you just have to repin about 6-8 wires on the EEC connector and run about 6 new wires for things like the VAM, boost control solenoid, knock sensor, BAP sensor, and I think it uses a 3-wire O2 sensor, whereas the ranger uses a 4-wire, so there is a bit of rewiring there.

Then you have a choice of running a Dizzy (like the TC) or DIS (like the ranger). Both the ranger and TC EEC are capable of running either system. But you'll have to rewire something. If you keep the DIS, you'll need to repin/remove a couple wires from the EEC connector. If you run a Dizzy (which also requires the turbo intake manifold, which requires the turbo head), you'll have to splice it into the wires that currently go to the DIS components.

The dual plug DIS head has fast burn combustion chambers, whereas the single plug turbo head has slow burn combustion chambers. This means that if you keep the DP head and use a turbo EEC, the turbo EEC commands too much timing for the fast burn head, resulting in annoying pinging (also bad for the engine). My solution to this was only using the primary (passenger side) set of spark plugs, effectively turning the DP head into a slow burn chamber head, eliminating pinging. Just simply remove the driver's side set of spark plug wires.

this is in the force induction section isnt it? hmm well my brother has a turbo and manifold off of a TC also. his is 96 ranger and so far everything has been working fine and i beleive he is only running 10 psi but he hasnt had it on street yet so far no problems. works very well and i think it will be much much fun.
