500 Miles and running great.

 

Ohhhh sexy... so glad to hear this is working. How does it feel?

So, just so we are clear... 99/00 ECU, injectors, fuel rail, intake manifold, sensors, and coils connected to a 01+ VVT engine? I'm guessing all you did was relocate the intake cam sensor from the front to the back, correct?

(scurrys off to order ARP headstuds, MLS headgasket, VVTuner, reroute goodies...)

 

99-00 ecu
99-00 intake
99-00 Injectors
99-00 fuel rail
99-00 coils
99-00 fuel injector harness

VVT head.
Used the cam sensor from the VVT, just got the wire out of the engine harness and it reached the back where the VVT cam sensor is.

Friend shop has a dyno and he wants to see a before and after the VVT setup so car will be on dyno tmw.

 

Just FYI, one of my friends had the same setup and when the car got hot it would have problems reving. Hopefully you do not have that issue. He was running without VVT hooked up. We tried just about everything to fix the issue, but nothing worked. We ended up swapping back on his old 99 head and he has not had an issue yet.

 

You sir are my god damn hero! Props for you!

What's the VVT doing now, just disconnected? I thought you had a complete 01 motor, why put the VVT head on the 9.5:1 99/00 bottom end? Very interested to see what kind of power this thing makes.

 

Its is a complete 2001 motor, My bad.

 

Hmmm really, wonder why. Mine seems to be running great. When did his problem start. All of a sudden? What you mean by "hot"? Normal operating temp or over heated?

 

We swapped in the motor in the spring, probably around this time of the year. It was not till closer to summer that the issue started happening. Well generally it was hot outside as in 90+ degrees and it seemed to be when the engine got up to normal operating temps. The car was never over heating. At first it would just just rev very slowly above 6k. Then the limit would slowly start dropping lower and lower. I remember he called me one day on his way home from the beach about it not being able to rev above 2.5k while sitting in traffic. He pulled into a gas station and waited for the car to cool down and then it was fine. We swapped out just about everything we could try to figure out the problem and it kept persisting. Once the 99 head was swapped over it never had the problem again.

 

Hope I do not run into this. Thanks for the info.

 

Here is today Dyno sheet. Still no VVT working so this is a "before" pull.

Ignore the 94hp graph thats my LeMons car.

 

123 is pretty good.

 

The 'with VVT' plot should yield the same max HP.

 

So, time to beg for updates!

What's your current state of awesomeness, and how are things running? I'm curious if Shuiends issue has cropped up here as things have warmed up. VVT is still just chilling there disconnected?

 

I'm a friend of mikes.

I did the same swap in my 99, has been in for 600 or so miles no hiccups. made 120/108 on the dyno...bone stock.

Car is for sale btw!

 

EO2K, Still have not hooked up VVT controller but it runs flawlessly. No issues at all.

JETSWU87.....how cute it says "Junior Member" below your SN, someone must know you.

 

I'm seriously running out of reasons to not do this swap...

Thanks for the update, form both of you guys! Glad to see there's more than one of these running around.

 

Uh oh... https://www.miataturbo.net/megasquir...nms-ecu-69111/

I may be out of excuses if delivers

 

sorry to bring up an old thread but I am doing the same swap, an 01 engine into my 99. I'm having trouble with the spark plug wires. which wires did you use? I currently have NGK blues and the top filler ring will not go into the VVT valve cover. also, I have to do a coolant reroute because the vvt head that I bought already had the coolant hose adapter cut off. so I have to tap and screw in a new elbow to run my coolant to my oil filter. but my main question is what head gasket did you use? I currently have a 99-00 gasket on right now but I just ordered the 01-05 head gasket. should I just wait to slap everything together? thanks in advance

 

...and it's gonna get worse real quick if you don't get your **** straight.

to avoid being neg catted into oblivion, do the following:
1) post in the meet & greet. Tell us a bit about you, your car, & where you live
2) don't take over other people's threads or necropost, or ask questions that have been answered over & over. At least do some searching first man!
3) read this thread at least 5 times. It covers all the questions you have asked: https://www.miataturbo.net/engine-pe...athread-80469/
