The screaming warthog........

[stumagoo]

I have been without my old NJ for some time now and the NL build is taking its time but slowly its getting there...... I thought I would show how it has progressed so far....


the rear storage...







The engine mods.... - there is to be a water to air intercooler added in the near future and a 3.8 and if I can squeeze it up boost from 6 to 9psi although not sure about that yet.




and to fit the intercooler I needed some space ----






Yes the snorkel is a bunnings special..... but as I dont have a stock air box this will do me until I can get a stainless one made. but before that is the intercooler and a 3" exhaust

How are you compensating for fuel?

also in regards to the 6 to 9 psi boost... JUST GONNA SEND IT

[stumagoo]

NL ecu is tunable- new fuel tables and timing to allow for boost.... bigger injectors will be preferable
to run 9psi though

Interesting to see, cheers for posting.

Is there any point with a snorkel on a petrol engine? I just figured any water up high enough to go into intake would cause troubles with the ignition anyway

[stumagoo]

was having issues with heat soak and air supply..... - I had a K&N pod filter in there originally - also the intake noise with the current setup is crazy and having the intake in the engine bay made it worse. - In the fender worse again, this helps reduce it a little. But I am looking to a custom airbox as well as some other mods to lower the intake noise. (it really needs the throttlebody moving to the inlet side of the charger but that is a major PITA)

[aussieguy]

So SC14 charger?

[stumagoo]

Yep SC14. It's running about 2-1 on the crank which is putting it at its limit rpm wise. No idea how the commodore guys can run 12 psi on these I figure they must be running at around 3.5- 1 on their pulleys but it's still under $1000 for the charger installed so I am happy the low end torque is off the hook on the soft sand I can chug around at 700-1000 rpm Luke a diesel in areas where I could never have even dreamed of it before

[cruisn06]

What are you tuning with? I see hptuners finally added mitsu to there list.

[stumagoo]

Ecu flash and an openport 2 cable from tactrix

If you have a snorkel the ignition may have troubles but drying it out will fix most issues.

If you don’t have a snorkel, ignition issues are miniscual compared to bending a rod due to water in the intake.

thats very true however with the lift on mine the stock intake is easily over a meter off the deck..... I was never ever going that deep into the water..... so this is as mentioned to deal with other issues.... and it has helpd with them for sure.

[disco stu]

Good point. But are you really going to bend a rod with water intake on a petrol engine?

[stumagoo]

we had a guy here put the rod out the side of the block from water in the intake..... drained the oil (it filled with water through said hole) and refilled with what we had available in the group - the wagon proceeded to not only get out of the state forrest (20 odd kms) but half way home - another 20 odd kms - that was when the engine siezed


there is a video of it on facebook in the WA paj page - it is Rudi in a NL in a big hole - he starts it to winch himself out and there is smoke everywhere.... I would not be surprised if half the people here have actually seen it

[disco stu]

Fair enough, cheers. I might be mistaken, but I thought I remembered being taught specifically that diesel will bend a rod but petrol will just stop running. I wasn't sure, hence the question

Pretty keen to see that video. I had a look, the only pages it looked like it could be you had to join so I held off.

Sounds like they are a tougher engine than I thought given that treatment. I'm assuming it was running on 5 cylinders once that rod was out the side

[stumagoo]

be surprised if it was even running on 5 - sounded more like 3 or 4 when it finally got going... it had help on the worst sections where we were worried of not getting it through


video link below - flooded gen 2 is around the 7 min 30 - yes the bonnet is a diesel one but the engine is v6 and the snorkel...... well we found out he had removed the airfilter element - this meant the airbox was not sealed tight and the snorkel was pointless
