Hi Steve, been following your thread for a while, and have seen the amount of effort/money that has gone into it.
 
One quick question, did you plan to go this far into it when you decided to put in the v6?
 
And do you have a better spaced photo of the exhaust in the bumper? I'm keen to have a look. Do you think your bumper will have melting issues?

There has been a lot of money lost on poor trade services. It would have been a better scenario if this wasn't the case. 
If I had gone with the single throttle body it would be a completely different scenario but a lot of the work was always going to be done and more to be done. I'm enjoying the work so no big deal.
I will be fitting a steel sleeve to the bumper to stop the issue with heat. 
 
 

So it's been a busy week on the car with some positive results. Almost ready for tuning which will see the car ready for driving by mid October. Would be earlier but keen on reworking a few more things before I get behind the wheel.
Itb is pretty much sorted, just needs fine tuning before it's run on the dyno.

I cannot believe another month has passed but it has.. Fortunately I can say the car is now up and running with the car being run-in and tuned tomorrow. On idle, it sounds better than it has done in the past but it really is an animal. a lot more than I was expecting.
A lot has happened and lot more will be happening today before it shows up at the tuner. Its not perfect but it will be enough to get it over the line for the tuner. If all goes well, it will be going through final prep for the WP Challenge in a weeks time. We (tuner and I) will also be able too see if the sound levels will meet the tight restrictions of Wakefield Park. 
As for WPC, it will not be breaking any records aside from attempting to run reliably for a few days. A 1.10 is the estimated time I will be working on. A friend was running the NT01 on a Nissan S14 with 300kw which was doing 1.07 all day so I will be sticking with that tyre to see if I can have the MR2 in the same ballpark. 
Will have another update after tuning.
 

Do you have a passenger seat to take us for a ride?

All the best today.

Yes I will be bringing one along. 

After spending the day at CXC racing at Narrabeen, the car has not been run in anger as it was busy having the expected teething issues that you would find with a build like this. Having all these problems appear before the car in on the dyno being pushed is a good thing as it has already, potentially saved the engine.
There were two oil leaks with one appearing at the start of the day while the second one appeared late in the day. Th first being on the connector for the oil pressure sensor, the second being a pin hole in the oil cooler mounting plate. It has two welded bungs which had a porous weak point which was (fortunately) discovered before it was bolted to the dyno.
The coolant system was put under a suction test then pressure filled but it did suffer a coolant leak at the electric water pump once the car was up to temperature. The engine was stopped while this was resolved.
A portion of the day was lost chasing more defective wiring by a guy in Victoria who now claims he can wire Haltech to 2GR. This is a joke as it continued to be a PITA right up to this point. Even so, there will be ongoing work to the loom at the start of the new year to really clean it up to a truly reliable standard.
The cam sensors were then next ones to slow down progress as it was unable to initially find synchronisation between Crank and Cam sensors. After solving the wiring defects, we found the home signal but the other three were not communicating. I was aware of the ‘pull up’ required but was meant to be sorted by Haltech but they only had this option for the Home signal not the other three, so we added a few pull up resistors then were in business. Even so, this was a 90 minute exercise in phone calls back and forward to Haltech until it was sorted.
The itb’s were checked to make sure they were balanced but they were out a little but overall, not too bad, so after spending countless hours with the fabricator it seems to have pulled up ok at the right time.
Near the end of the day the addition of EGT’s to the engine control system with every port now being monitored, immediately confirmed their worth by pin pointing a problem with cylinder 6. It was cold in comparison the rest. My immediate call was a dirty injector filter but after testing all possible outcomes, the injectors were removed and tested to discover the injectors did indeed have dirty filters which were blocking the injector flow. The number 6 chamber had basically no fuel flow to the point there was nothing to burn. Without the EGT’s it would have easily been overlooked then possibly broken the engine during tuning of overlooked.
So even though the engine did not run-in or tuned, managed to have a lot of key points solved before we get down to business tomorrow morning.  
It was revved a few times when we were running the various tests with a amazing sound. A bit like a 3.6 litre superbike motor. Such a great song!
