I dont think there's much benefit if you are going to be redoing a lot of the wiring anyway.

There's a bit of a learning curve when going form MSI to MSII/MSIII, but it's really the same ol program with more windows and features... the main thing will be learning how to tune PID.

Less possible causes of failure at once. You could get the MS3x up and running on the 95 running sequential fuel and wasted spark. Then convert to sequential spark. After that then drop in the VVT motor. This way you know the ECU side works and all you have to do is hook up the NB sensors and the VVT wire. I guess I just like doing things in steps now.

Random side idea. Why not put the MS3x in the track car with the VVT head. Then put the 01+ block with the 99 head in the DD. Also swap over the mspnp to the DD. I think you might get a bigger benefit in the track car with the VVT and MS3x.

Because he has the track car dialed in to a T on the motor/tuning/reliability side and he isn't looking for more power. I think Trey is only running 10psi at the track.

Somebody please find a source for BP-Z3's. Also in for gas mileage report of a VVT/6sp/3.63 car as a hwy commuter. I'm betting its a 40mpg car.

sorry, 136whp on Dynapak is what a fresh stock 99 engine make with a good exhaust.

on Dynapak, my motor made 169whp (but 148whp on a Dynojet).
I have a freshened 99 bottom with 10:1 pistons, square top, RB header, HDM intake, junk yard head, Adaptronic and no cat.

I would switch over to VVT if all the electronics can be worked out for a electrical retard like me.

I think 150whp is easy for a vvt with a few bolt ons.

Yeah, my track car is done and needs nothing. I only run 11psi on it, and it gets the job done. If I turn it up to 16psi, it still hits that number at 3500rpm. I could probably get more output but at 242whp/235wtq, it's fast enough. I'm making 215wtq at 3500rpm at 11psi, there's no point to changing it. Now, if I had a 2871 or something bigger, that might make sense.

I think 40mpg is doable if I hit the sweet spot of that cam and lower throttle position for cruising. I'm going to attempt to do this swap in a weekend too, that should be exciting. Maybe I'll wait until it cools off and drive my track car to work for a week or two.

The car probably needs an engine and I'd like to do all of this shit at the same time. How hard is it to source the pig-tails since I'll need new connectors for the CMP, CKP, VVT, and TPS?

stock is about 120 on a dynojet.

I think I managed 104 on a dyno dynamics.

there isn't much room for improvement with intake and exhaust beyond replacing the cat and stock muffler.

maybe a tiny bit in tuning (probably more gains in mpg than hp)

150 might be a challenge.

don't we get more range of adjustment on the cam with MS3x/VVTuner and does that increase range make a difference?

Need a MS3x? I may have one for sale :)

I'm wanting to do a 99+ engine in my 94 sometime next year. My poor old stock engine is worn the eff out. Thinking about a diypnp in the stock box, STR legal, tehe. I wonder if an ms2 & vvt controller would fit in the stock ecu box....

honestly don't know the full range used by the stock ECU. need someone with a stock car and megasquirt to log that. in any case, running the maximum advance might not even make more power.

and for the posterity, stock dyno charts mentioned above.

look at that ruler flat torque curve dawg!

Just like my HP curve.

I think Emilio dynoed 159 with a .5 higher comp, jdm cam, jdm square top, and jdm 4-2-1, and some bowl work. That same day William picked up like 8hp from a straight shot intake or what Emilio picked up with bowl work. So I think with a square top, nice header/exhaust, striaght intake, and some mad tuning 150whp is in range. Aren't those dyno dynamics the heart breakers of the dyno world? 104 sounds retarded low, thats low comp 180k 1.6 power.

Basically Emilio and probably William are the authority on the VVT power swaps.

ok maybe with a few bolt ons, an unobtainable jdm square top manifold, and a bit of DIY grinding on the head.. :)

and yeah, I made it on the "Wall of Shame" at Vishnu.

I mean more midrange torque in the track car is always a plus, but whatever floats your boat.

For all the connectors the easiest way to get them is to buy a 01-05 wiring harness. They can be found for between $40-$100 depending on who you get it from. The biggest thing is actually finding someone with one. I think I spent a few months trying to find one. I would suggest starting to look now.

Also why not just keep the 95 throttle body? It bolts up fine and that way you can reuse the idle and TPS that you already have.

You need to source a 99/00 fuel rail that has the flange for the FPR on the front.

Also might want to look into a 99/00 IM instead of the 01+.

Wait. What happened to move for GF thread? Outcome needs to be posted

GF=VVT hwy burner for Dallas to Houston cannonball run

Savington just built/installed my 01 motor into my 90.

It's 84mm, but the CR is the same, 10:1. Head is stock, but refreshed. 12 tooth wheel, sequential, ID 1000's, and AEM. Cheap eBay header, 2.5" exhaust.

6 speed with stock 90 diff (just for now), whats that? 4.3? 4.1?

TSE's dyno was acting up a bit, and showed 200 WHP, we know that's not true. Butt dyno says 140ish. Very torquey (sp?) And VERY fun to drive.

MPG's with mixed driving, 33% street, 33% hwy, 33% WOT tearing up and down mountain roads, is 25-27mpg. I may get a tank of just hwy miles next week. I'll post up the #'s.

Even though my motor isn't stock, and not a direct apples to apples comparison. I'd say it would be totally worth it. I'm enjoying mine very much.

Partsgroup sells them for $45 and when I bought mine a couple of months ago they said they had a bunch of them.

Got mine from Panic Motorsports. Not sure how many they had, and this item is more of a PITA to find than the wiring harness because it is one of two different fuel rail styles used on 99-00s. If you deal with a parts supplier who is not a Miata specialist you need to be detailed in your request or they will probably send the wrong style.
