Hey there, all, I'm quite sure there have been no posts about this specific topic, or the many searches I performed would have yielded me something. I come to you all, though, for your expertice in turbocharging the KA24DE motor. My stock 143hp just isn't cutting it, and I've now found all the parts I need to complete the installation of a Turbonetics T3/T04B hybrid turbo with a Deltagate wastegate onto my truck. I'm looking for roughly 350hp @ 13-19psi. In case it matters, I'm looking at a Super .46 compressor wheel in a T04B comp. housing (3" inlet) with a wet ceramic ball bearing center section, coupled to a T3 tangential turbine housing with a stage II wheel and .63 A/R. Yes, I'm rebuilding the bottom end, and intercooling the charge. My concern is for fuel delivery. What do I do about the fact that JWT doesn't have an ECU upgrade? Is there some way to control my engine timing and fuel trim easily/cheaply? If anyone knows this, I know you guys do!! Help me out, here, please. John

Sounds great, I have a 1998 Nissan Frontier and I just turbocharged her 3 months ago. As far as for ecu setup, I am running the APExi SAFC and silvia injectors(380cc) to flow fuel along with a FMU, you can do this or buy 450cc or 550cc and do away with teh FMU and just run the SAFC. I have had no problems, running 10psi now and she is ripping the streets up and many many cars along with that. I have a simple setup, and at 5psi she pulled 175whp, and 187 tourque, which stock is about 123whp, so 50hp bolt on with a homade kit at 5psi, now she is at 10psi, and I can tell a big difference in power, she goes back to the dyno shop friday to get tuned at 10psi to see what hp numbers she puts out, good luck, hit me up, I deff would like to chat, only other frontier I know of is yours that is turboed,besides mine...

also, if you would like and have knowledge of turbos, you can do the same as this guy in FL, 400whp in a KA24DE stock ecu/ stock internals, with mild upgardes, same setup I have besides fuel pump and I have a IHI ball bearing turbo T3...http://www.back-yard-productions.com/CONROY.htm

Thank you, that is EXACTLY what I was looking for. Fuel delivery was perhaps my biggest concern, but now I know I can leave the ECU in stock form, and add the SAFC. I plan on simply upgrading the four main injectors, and fuel pump, plus adding an adjustable FPR. All in all, how hard was the SAFC to wire up and tune? I thank you again, that was a big help! John

The SAFC is not hard at all to wire up, it is a sinch, if you have basic electronic and wire diagram know how. tuning was not too hard, but the best way to get it right is to run it on a dyno, I had it in and thought she was tuned right, I put her on the dyno, I did have plenty of fuel, but way too much, so I played with the SAFC and gained 11hp at the wheels, not tuning but just guessing by looking at my a/f on the dyno computer, so with a good tune you could pull as much as 20 wheel hp out of it.

also here is a pic of my setup, not a great one but the best I have for now...

Thank you for the input, I think I'll do just that. The only other option I was considering would have been a Haltech ecu, or fuel/ignition computer. For a while I was affraid there was nothing I could do, but with enough dough, and forums like this, I suppose anything is really possible! John
