How to turbo your NA for $2000.

[NitroDann]

Megasquirt was 915 including everything needed. The turbo was 80 bucks, the oil lines were under 100, the filter was 30ish and the rest is just 10 bucks in silicone, 10 bucks in clamps and a downpipe and crossover tube.

Do the maths yourself

So this is it, the end of the '2K Turbo NA' build.

The final steps are straight forward. And the owner has recieved it.

Ive refitted the heater hoses, and here Ive used a little heat proofing for insurance.


The megasquirt instructions have all of these steps, but here they are, fit the vacuum tube through the firewall.


Here is where it goes on the TB, this has a little blocker from the factory.


The AIT sensor gets plugged in here, the loop joining the last 2 arent needed on new megasquirts as I found out (didnt trust the instructions lol, I was wrong.)


Here is the sensor on the pipe.


Remove the ECU cover on the passenger side, this rust is OEM, dont believe me, check your NA haha.


Heres the oem ecu.


Unplug it.


Replace with MS.


Add the serial cable for porting and hook the other end of that vacuum tube to it also.


Worst photo sorry, but here it is all finished.



From here hook up a wideband and street tune as I did or take it to a dyno. This will get tuned at IS Motorsport in the next couple of weeks it seems, so we will know for sure exactly how it performs.

This boosts from 1200rpm, with no lag at all.

None.

Zero.

Period.

It feels like a 5L swap or something. Just non stop torque. 7psi at 1500rpm torque. Just a wall of nonstop torque.

If you cruise at 60 in 5th and hit a bump and your foot moves, guess what, 5psi haha.

I hope this helps some people and makes a lot more people comfortable.
It was easy to tune to be safe and still make good power. It runs great, very smooth. No issues without the BOV at all, and no pinging, because it simply has a conservative spark map.

The owner will give me a review in the next couple of days after having it for a bit and Ill post it up.

Thanks for everyone who was involved in the thread, I wouldnt write this stuff up like this if it werent for you all.

Awesome thread.

What's the dyno-tune going to cost?

[plohl]

Curiously, what intake air temps are you seeing?

[lightyear]

Well done Dann. Track set up next...

[corners]

You may have mentioned it already but I searched through all the pages. What is controlling the boost? If its just wastegate pressure are you then plumbing a line from the intake pipe to the wastegate?

Awesome thread.

Not sure, the basemap has starting and idling pretty much spot on, also accel enrichments are good, it just needs the spark and fuel table tweaked.. soo, 2 hours at 120/hour I guess.

Curiously, what intake air temps are you seeing?

Good question, I was flat out and never even looked. Very good question though.

Well done Dann. Track set up next...

A few have asked yes.

It has the nipple on the turbo compressor looped directly to the wastegate actuator.

That's a neat install - like the crossover pipe.

[ivan]

Very very cool! I'm keen on doing a track set up if you have the availability. PM sent

What's the hit to the fuel economy like?

[NitroDann]

It should be better than stock, conservatively dríven.

I think I may have to eventually take a trip up to Newcastle

[OzGuvnor]

Following with interest

[peterd]

me too. how about engineering any issues with this. cost? is it a state by state thing if so can you drive the car anywhere?

[NitroDann]

It would need an enclosed air filter, and a tune that will pass an emissions test, then an emissions test and engineering.

Probably factor is 1000 extra, maybe 1200.
