Going 420a turbo soon.

[AE2499]

Alright so I’ve pretty much been doing research for about a year now and understanding what a turbo is and how it works. So I have stock internals since it’s a new rebuilt engine. Saw that FMU & FCD is like almost $300 so might as well do it right. I am saving up right now for MS3 $900 and then a 1:1 fpr. Gonna keep the boost psi low 7-8 since it’s a stock internals. So far I have:
-FMIC
-HKS BOV
-Turbosmart External Wastegate
-Walboro 255
-Intercooler piping
-Turbo Exhaust Manifold
-Oil feed/return lines.

What I need:
-MS3
-voltage regulator for alternator since standalone ECU.
-1:1 FPR
-Bigger fuel injectors (reccomend please)
-AEM Wideband
-Oil Gauge
-Boost Gauge
-Custom Downpipe
-T3/T4 Turbo

To me this seems like everything I need to build this 420a. Let me know what else you guys think or what else I might need down this path. And yes Ik I will get forged internals whenever the stock one blows.

365cc injectors are fine at 7psi. Fuel Injector Clinic makes a set for $370. But if you ever planned to turn the boost up or other aggressive mods then I would just buy the 445cc's and be ready, tuning accordingly of course.

Might wanna add a turbo to that list!

Ok, So would 445cc be fine with 7psi stock block? and then if I upgrade to rebuild block with forged internals, would I still be able to run the 445cc's or would I have to upgrade?

O forgot about that but I just updated list.
Also does my list look pretty much complete on what I'll need?
Would I still need an Fuel Cut Defender if I use Megasquirt? Pretty sure not since it would have it's own map sensor built in it right?

Voltage regulator? You already have one.

No I don't have one yet. Just saving extra money before I get anything else. Want to buy the MS3 first though since I know it takes them time to make it and ship it out. Let me know what else I might need when going this 420a turbo route.

All cars already have one as part of the oem electrical system.

Yeah, but I'm going to be running a standalone ecu so I would need an external voltage regulator.

True, the voltage regulator is inside the ECU. If it makes you feel any better, you can get a standalone regulator from an '88 Dodge Omni for $20 rather than replace your ECU.

If I remember correctly, you should be able to use Evo 560's as long as you wire in the resistor pack as well; you can find them for cheap and they should be good to cover you 7-8 psi plan. Www.2gnt.com has a ton of information about stuff like this. I think that's what I read (regarding injectors)and was gonna use them back in the day when I was working on putting together a kit for my GS. The voltage regulator that you're looking for can be found on Amazon and even AutoZone . I've bought them from both places. The pigtail for the regulator , I believe I got it from Amazon, but could be mistaken.

They have more expensive ones, but I am not sure they are better quality.

Yes, I will be getting one. MS3 from DIYAUTOTUNE is about the same price, should I just get the MS3 gold box then?https://www.efisource.com/wp/shop/ms3-goldbox-with-8ft-pigtail/

If the only thing you replace is the internals then the 445cc would still be fine. Especially if you were lowering the compression ratio.

The only reason you need anything larger is if you plan to run E or turn the boost up above 10 pounds. It requires much more fuel at that point.

Alright, so 445cc should be fine for 93 and stock block. So then I would need around 650cc or bigger to run e85 and up the boost?
