93 4X4 Hardbody Boost Project

[PaulC]

NGK Iridium in 7, the coldest, but you'll need to gap them down for a boosted application. .032-.035 is what I've seen recommended.

Thanks for this info, just out of curiosity, did you do something similar to your 93 or is it oem? I’m trying to wrap my head around this mspnp standalone ecm and I’m trying to gather up as much info as possible before I make the actual swap.

No I haven't done it myself. Though you should check out ka-t.org I bet all the info you need is there.

Megasquirt was the best investment you made with this whole project. Whether you have a budget eBay setup, or a high dollar build, they'll equally destroy your engine without a proper ECU management like MS. Remember not to drive in-boost once you get it running. Go straight to the dyno tuner.

The Holset 35 is going to be way too big for your goals on the KA and come on live late in the RPM's unless you're fine with that.

Looking at your red-intake picture - where is your valve cover breather going? It needs to be vented to open air/atmosphere once the engine is turbocharged. It can not be plumbed back into the intake or any pipe that sees boost.

You don't need a pump for your oil feed going to the turbo. Getting it from your oil-pressure sensor provisional is fine.
I didn't see any mention of your oil-return line coming out of the turbo? Plumb it to your oil pan as high as you can (has to be above oil level) when you do the oil pan gasket as planned. Make sure the line is 5/8" or -10AN minimum and a straight shot into the pan. It is a gravity drain; so no U's in the line where it can get backed up.

Good luck! Post pics.

Great info and much appreciated. I am aware that holset is a donk and just for the novelty I’m gonna run with it, at least, for the time being. ka-t.org has been fairly helpful in certain areas but man it’s like a ghost town over there, maybe I was looking in the wrong area lol. This is my latest situation, trying to plumb my own custom welded exhaust and figure vacuum and emissions bypass/removal now. Still hesitant to install the ms v3 because I am worried I guess, the old ecu worked just fine for stock lol. figured once I get everything mechanically back to where I want it without plumbing the final piece of the ic piping in to complete the cooling circuit I will fire it up one last time with the oem ecu, check idle, timing and a/f ratio so I have a base line then swap to the ms and put the old girl on the shelf.



Man that turbo does look outrageous lol probably weighs close to half of what the engine block weighs….well maybe not but damn. I removed this thing from work and before they were gonna scrap it I said stop I’ll get a rebuild kit for it and put it on a gokart or something lol maybe this would be a better option for the hardbody it’s a schwitzer s1 off of a duetz auxiliary sweeper engine lol what an oddball I have no idea what style flange this is. It’s a perfect triangle 3-bolt

Not sure if anyone can help me out with this and it’ll probably be considered a noob ass question because it is lol am I gonna need larger injectors and if so once the megasquirt is in do I still need a different regulator or could I just swap the regulator and use the same injectors up to a certain hp? I keep finding opposing info and now I am thoroughly confused lol I know somewhere in an old forum on here I could probably find an answer but now I’ve already gone and purchased an adjustable fpr with boost reference and I’m not sure if I still need to install?? Any help would be very much appreciated.

[Myst69]

Well that was a little involved but after some maneuvering it came out almost in one piece lol

[Myst69]

Here is my downpipe configuration, these two get bolted together.

Here’s the fuel pressure regulator and what I had thought was my mspnp v2 but is actually mspnp v3 and the new electronic boost controller I ordered to go with it.




That last one was $850 wifey was not happy and cost was well over half for what I paid on the entire truck lol hoping it was I wise choice

Hey man... your PICs, for the last couple of posts, are not showing. Don't use the "URL" for the page, R-click on the image you want and choose "copy image address". This is what goes within the [IMG] tag. Understand?
