I wish I had the coin for one of those, it would really complete my rig
So I FINALLY got ahold of the Sprintex guys. Here's what I got...
1) The website says "Kit can be installed using the factory fuel injectors and fuel pump" but the site also says "This kit includes 2 extra fuel injectors which provide the additional fuel required only under high output conditions such as hill climbing or overtaking also includes injector wiring loom and diagram."
Explanation: You retain the original injectors and fuel pump, but have to add 2 extra injectors for when under sig load/max power. Given the age of the 80, they recommend a new OEM or similar fuel pump, but it will work with the stocker as-is.
2) The XEDE processor is indeed a "piggy-back" computer that installs on and takes control of the factory ECU, thereby allowing for continued OEM diagnostics, OBD-II port functionality, etc. The XEDE also controls the OEM fuel system in addition to the 2 newly added injectors.
I did a quick search online, and it looks like there's a fair amount of local (US) XEDE support, especially in the Miata community (which is a GOOD thing, cuz they have a HUGE community).
3) The site also recommends an "Automatic Transmission upgrade." This is in reference to the 100 series/later V8 models. Not an issue on the 80 trans.
4) I expressed interest in running the supercharger with a top-mount intercooler (vs the water-to-air IC setup they provide). He strongly advised me against it, given there's very little distance between the core and top mount IC, plus placement toward the exhaust side of the motor, all contributing to heatsoak. He didn't feel this would be efficient or helpful.
5) I asked about a Rotrex supercharger unit instead of the Sprintex. Short answer is no. The Rotrex is a centrifugal supercharger, so it provides very little low-end, which is why they use it on their smaller/sport compact/light vehicles. For a heavy application like our 80s, the Sprintex is the way to go, since it'll offer significant low-end power and torque.
6) Last but not least, exhaust. They have a full exhaust (headers to catback) for $1695 http://www.bulletcars.com/parts/engine-parts/bullet-ultimate-exhaust.html#bulletult1fzfe. I'm not sure if it would be bolt-on on a US truck, but I'd imagine so. That's a pretty darn good price for something that's already ceramic coated (compared to $2400 for EMS Powered's header + exhaust system, which doesn't include ceramic coating): http://www.emspowered.com/storefront/index.php?main_page=index&cPath=61_119_120_121.
So I just may take the plunge on this one...

This one is on top of my wanted list and has been for a long time, half way there with the cash

i work in the trade hoping to get it at trade price when i do. most of the time all the things i want are in the US and have to pay fright to OZ.so i feel lucky about this one

Thanks for following through with this, it sheds a lot of light on things. Good to know that the Rotrex unit isn't suitable for us.
Looking at the Sprintex unit, it appears to be similar to the TRD supercharger. Any particular reason you're looking at the Sprintext unit over the TRD unit?

2) https://forum.ih8mud.com/showpost.php?p=7530231&postcount=9, especially the last 2 lines
I would imagine it's possible to use see similar power gains with a TRD supercharger, if you intercooled it, added injectors, and used the XEDE ECU as well. But I'd be taking a risk on fitment/fabricating parts to mate together, which would only be an added expense, and not covered under any warranty (cuz I'd be one-offing it), vs purchasing a complete plug 'n play system with promised compatibility and performance #s.
Let me know if I'm missing something...
Correct?
If that's the case and out of curiousity, why not go for EMS's Stage 4 Turbo kit for $9,050 which includes the ECU, Intercooler, and Exhaust?
EMS Powered 1FZE Stage 4 Turbo Kit
- Super Charger $4,500
- Intercooler $1,995
- ECU $1,250
- Exhaust $1,695
Total $9,440

1) I'll be honest w/ ya...I hadn't seen the EMS Powered turbo kit before.
2) Stage 4 and up seem to require an ECU. What ECU are they running? I REALLY don't want to ditch the stock ECU for diagnostic purposes. And the only stand-alone I know that will retain all your OEM diagnostics is the Apexi Power-FC, but I doubt they make an application for the 80 (granted you can still use a universal unit with a base map and tune from there, so it IS doable).
3) So the Stage I-III make double the factory power on the factory ECU and fuel system? That sounds a little worrisome (running upper 90s injector duty cycle, etc. And how is the ECU compensating for the additional airflow?)

I'm not well versed in Turbos or Superchargers or ECU's for that matter. It all intrigues me and that's why I posed the question. They are running the AEM FIC6 or FIC8, which seems like a universal unit.
I cannot answer #3. Hopefully baktasht sees this and can chime in.

Yea I'm pretty verse in the aftermarket sport compact world, so I'm familiar with many of the ECUs available. Not a big fan of the AEM, and it is indeed universal. Not a programmable stock-like unit (ie retains factory codes and diagnostics) like the Apexi Power-FC, and not a piggback to the stocker (again retaining factory codes and diagnostics) like the XEDE.
That's a REALLY big point for me, because more important than the additional power is RELIABILITY. I'm not looking to make this truck my toy. I want it to be my dependable workhorse.
That's also one of the reasons why I shyed away from a turbo diesel swap, cuz you're fabricating all sorts of wiring etc which if not done perfectly can be an ongoing disaster.

Got ya, thanks for the response and if you pull the trigger be sure to document it and post up your findings.
I hope you're not comparing the XEDE to the FI/C 8? The XEDE is crap. haha. It has nowhere near the tunabiliy of the FI/C 8. The FI/C 8 is an actual tunable piggy back, while not as ideal as a true standalone system the 80 series TCU controlled transmission makes a true standalone a hassle because you also have to run a standalone for the transmission.
I would suggest that you go back and review your selections. The Apexi is a basic standalone without any of the power of a real standalone power house like Motec, Haltec, etc, and then your piggy back is only a plug and play adapter not a tunable system. I think you will see that for this application the FI/C models are a good unit. The other unit that looked very nice as a powerful tunable piggy back was the Haltech Interceptor which is no longer made.

For stage 4 and up we run the AEM FIC8 in conjunction with the factory ECU, therefore maintaining full diagnostic and OBD2 functionality while allowing us to finely tune both timing, fueling, boost levels, and multiple tuned maps that are switchable with the flip of a switch on the dash. We also have a plugnplay setup including ecu and gunplay harness and switches needed available to the public for people that want to run setups other than EMSPowered and still want a fully tunablr setup that can easily be removed to go back to stock by just plugging the factory harness back into the factory ecu.
Well that's for the 4.7L V8, not the 4.5L 1FZ-FE we have in our 80's. but you will face the same issues of fueling with it. I had a 4.7L with the TRD supercharger.
He is not wrong.
You will need AT LEAST an extra oil cooler for the auto, and a heavy duty torque converter and valve body would seriously increase the performance.
I travel a lot in an uncle's supercharged 80 to our ranch and being heavy on the right foot will overheat the tranny without an extra transmission cooler. This car has the a442f. This also happened on a supercharged 90 series prado with an a343f, so both gearbox offerings for the 80, the a442f and the a340f, will suffer due to the extra power of the supercharger.
Yes i have the 4.5l 1fz-fe in my car too. you didn't scroll down did you ?

Haha! No I was on my phone.
Awesome. Thanks for the info.
What about for Stage 1-3? How do you manage all the extra power (up to double the stock power) on the stock ECU and fuel system?
Also, is anyone on the forum running this turbo kit? I did a search and didn't find much feedback...
Lastly, what do you guys typically charge for install of the kits?
EXPENSIVE (in light of the EMS Powered kit.
Ah thanks. I don't think I really noted this in the supercharger threads I've read. So the trans cooler is relatively easily accomplished, and I already have a trans temp sensor & gauge. What options are available for the torque converter & valve body? I can tell ya I def. have a heavy foot...
