Hello everybody, so I thought I'd jump right into it. I'd like to talk about current tuning options for a 10vt, specifically going efi/standalone and I'd like to hear COP conversion ideas/setup's. I'm swapping a MC2 10VT from a 89 200 into a 87 4kq and would like to modernize the 10v a bit. Most people will start by saying to swap in a 20vt instead but I want to keep this thread on task...10vt only. I have another project involving a 20vt anyway and I just feel as if the 4kq and 10vt are meant to be together. My aim is for ~300awhp using e85 with a useable powerband from 3000rpm-7000rpm.

So I've been doing a lot of reading and searching and it seems as if chips are no longer available and there aren't any off the shelf/turn key efi systems so that pretty much means:

Work with the stock cis (no thanks)
Piece together an efi...something like megasquirt....OK, but...

What about your ignition timing and boost control? Not very many options there.

So now we've got to work a band-aid around the ecu.

Find an old chip...but then you're limited to the stock turbo....or...I know there's a way to bypass the ecu's ignition and boost control (someone can chime in on that, it passes my mind right now) but then you have no rev limiter...problem solved...msd ignition or whatever ignition system you like.

Ok...onto boost control...electronic boost controller or MBC with a stiffer wastegate spring...pretty simple fix.

At this point though there's a lot of money being spent to work around an antiquated ecu/fueling...and I haven't even started talking about COP conversion and the compatibility of that. So the logical progression in my mind at this point is why not simplify the whole thing and go standalone?

This is where my questions really start...

What standalone does everyone recommend? MS3, VEMS, Haltech, etc...? Personally I'm leaning towards Haltech 750 based on a recommendation and some mild research into it. I'm looking for something that has flex fuel sensor and some form of two step/"launch control".

What is everyone doing about ignition? Specifically COP? Is everyone just using the hall sensor in the dizzy to get their cps signal or is there some way to go distributor-less? I worry about high rpm accuracy. I may not be going for a lot of power but I plan on driving the car like I stole it. I like to run something like ls2 coils so I can cleanly mount them on the fire wall. I'll still need an ignition module like a MSD, correct?

Obviously I'm looking for answers to help my build but even if you have something to contribute to the 10vt engines then please post. It's hard to find information without some serious digging so it'd be nice to open up the discussion about these engines again.


Tl;dr...
I want to hit 300 awhp on e85 with a mc2 swapped 4kq using a standalone ecu with a COP/individual coil ignition, preferably distributorless and has flex fuel and two step/launch control compatibility. I can use the distributor if I have to if it's the only non complete pain in the ass way to get cam position.

Thanks in advance!

I know the MS3X will do everything you say and more. I'm pretty sure the VEMS will also do it all as well. I have no knowledge of the halltech system.

I'm running MS3X on my MC1 with LS2 coils. I shortened the dizzy a little and kept the hall sensor for CPS. I am also running a 60-2 wheel with a hall sensor for crank position. The 10v head is pretty well maxed out(in stockish form) at 7k RPM. I have a PnP head, oversized exhaust valves, high rate springs, and Ti retainers. I have my rev limiter set to around 6500. All in all it works quite well.

6500 is acceptable. My friend and I (he's the welder, not me) will be building an exhaust manifold using jim green's as a template/inspiration. Honestly I can only hope it will turn out nearly as nice as his but my friend is a pretty good welder. Hopefully that helps with some flow.

I am re/building the motor, I have a decent parts collection started and was planning on doing some head work...springs, valves, retainers and maybe a little cleaning up of ports but I didn't plan on going too crazy. Just want to throw new parts in there as I'm gonna keep this car for a long time and I'd like to see it go another 300k.

Sounds like your setup is pretty much what I'm looking for, just wasn't sure if MS3x would do the trick. I'll have to join the ms forums, I've been browsing there a little.

I am going to use the 200 flywheel, I've got an entire donor car for this fortunately. I know there's a 60-2 rms available as well.
