INCREASING TURBO BOOST TD27

[sibainmud]

Yippee

err you going to relocate the air filter? or leave it very very low??

Pedro

Yip, that's for dry stuff. Just out of shot is the tube that is connected to the snorkle, takes 1 min to fit link tube to snorkle.
Snorkle is too much restriction for everday off-roading

Simple but effective

[marmel]

With that cone filter position you will be sucking in huge amounts of hot air coming off the turbo, sort of defeats the purpose of having the intercooler?

[Damz]

Anything is better than nothing
I had to reverse the polarity to get mine to suck instead of blow.

Cheers,

You also need to pull the fan blade off and flip it

Lol. Then enjoy being back where you started

No, think about it, same had to be done with my fan, you reverse the polarity of the motor to get the motor to spin the right direction for pulling and not pushing, then you need to flip the blades to make them work in that direction too.
It's all explained on the instructions in the box.

Oops, dead right. Cheers

sibainmud, is there a noticeable power difference between havin the snorkel plumbed up, and the open pod filter?

sibainmud, is there a noticeable power difference between havin the snorkel plumbed up, and the open pod filter?

Also, what do you use for a filter when the snorkel is connected?

Time for a bigger snorkel perhaps?

Yes quite noticable. More black exhaust smoke with snorkle.

Also, what do you use for a filter when the snorkel is connected?

I use the same pod on top of snorkle, or like i have now, a pod on each place. The filter ontop of snorkle has been heavily oiled to keep the water out. Swap over is easy.

As this engine is a converted turbo, I never had the filter housing for it, so did the best and cheapest. Haven't noticed any heat.
The pod stays cool enough though, as all the heat shields are still fitted. During the middle of summer, I did notice a slight loss of power from over-heating boost pressure.

Back to the shed, got to fit a boost controller and set it to 18psi.

Interesting, as mentioned earlier, wonder if a larger diameter inlet pipe would help? Either way, bet it moves.

Dont forget pics of the BC install!

Ok, Guys. I have had the chance to do a road trip with Intercooler and Boost Controller.
Here's some stat's.
Going up the Bombay Hills on the South side, heading north. For those of you that don't know it's not the steepest but is long (saw 2 cars over-heating half way up) and open road speed limit.
Right, I was towing my tailer loaded with mud tyres and tools (350kg's). Slowed before I got there, 2200rpm 8psi boost. Put my foot flat to the floor, and went to 18psi boost. EGT (Pyro temp) never got over 500 DegC. 3/4 of the way up lifted foot cause speeding at that stage
Engine temp went up a bit (radiator blocked with mud from weekends antics ) to just over half.
I pulled away from everything going up same hill (3 lanes wide).
Pulls like a schoolboy

[Damz]

Awesome, good effort bud. Gives me the confidence to run more boost, I always had people telling me I was nuts running 10-11psi in the navara, yeah right!

What temp is safe on your EGT gauge? Any pics of that? Cheers

Pics of EGT earlier in thread. Most experts say 700-780 or so DegC max.
Not bad for a non-turbo motor still with the same fuel pump.
There is more room for fuel but as it is non-turbo pump it would black smoke badly till some boost is rammed down it's neck
I think I have cracked it IMHO this is perfect.
P.S. Was running around with some "Hard-Core boys" all weekend. They all had LexPOS powered or V8's with a couple of TD42 'fari's, kept up and even drove some hills and rock climbs that they couldn't. Impresed them

Whoa so heaps of room to heat up yet. Excellent!

Now all I have to do is copy your steering idea and Ill be sorted

Should start a thread on that one too, if there's not one already.

You ABSOLUTELY should, would definately be a sticky.

Your new name is still "THE RAT".....you know why

The words "up a drain pipe" still ring in my ears.

Time to dredge this one up again.
I have a few developments in this area.
While I have no problems with the engine handling the extra boost, and fuel. All the engine and exhaust temps are all under control, running it for over a year with no waste gate connected and at times over-spinning the turbo has it's affects
Even though I have now fitted a boost controller to lower the pressure to 18psi, the damage to the turbo shaft may of already been done
While driving around at "Nana" speeds the turbo gave up the ghost with no warnings at all
So, here's the pics, (since all you guys love them).







So, after talking to a guy that is pushing 30psi down his TD27, and he has blown up a handful of turbos, the recommendation is don't go over 20psi with a standard turbo
Fitting a new second hand unit now. Good thing is it came with a 30 day warranty, so I have a month to blow this one up

[Big Will]

^^
Yep, thats F*&Ked..

[Damz]

Out of curiosity, whats a 2nd hand turbo worth for a TD27? Iv been offered a '95 turbo with manifold for $300, 60,000km. Thinking about it after winding it up, and reading this.

[sibainmud]

$250 + tax. With 30 day warranty. Not the cheapest but easy to source. Cheers,

[Damz]

Sweet, thanks mate

[Big Will]

wouldn't it be a good idea to find something more suited to high boost and high shaft rpm?

[sibainmud]

Just another thing to put on the cert plate
My mate has done it, he's up to porting heads now, but his is dedicated off-road
At 18 psi it has huge horsepower for a 4 banger oiler
All Good Will. Appreciate your input.
Cheers,

Agreed. The TD27t really comes to life with more boost and fuel, amazed they didnt set it slightly higher from factory.

Would love a TD42t...

[haz4rd]

Hey guys you all seem pretty to the play on terranos. Can someone tell me where the idle screw and fuel flow screw is.

On the side of the fuel pump I've found what we think is the idle screw. (faces the firewall) when screwed in increases idle.

Any help would be greatly appreciated.

Cheers

Mike

[will i am]

im prity sure that 10mm nut/screw facing the fire wall on the injector pump is a bleed screw. undo it if you want air in the system

[JMR50]

Man I like the sound of increase turbo fuel = more power
be getting my 96 R50 2.7 manual box rebuilt next week + HD clutch ,new 2.5in exhaust -- have already done new brakes all round ,repacked bearings,new Alternator,K&N filter,Alpine Ipod head-unit
with 550w Boschman speakers in ea door bashplate(to be fitted)
will be re-flushing cooling system,have also just done the valve timing with 5 of the 8 needing to be let-off a tad.

EGT Boost gauge on the shopping list,along with better shocks

Mint body only 165kms on the clock.....hoping total costs to be sub 10k paid 5k for the terrano

best of all I'll be getting my liecence back in couple more weeks
Snowing outside yeah ha

[sibainmud]

be getting my 96 R50 2.7 manual box rebuilt next week

What happened to it? Just curious.
ETI-TD27's are a bit tricker to play with cause of the flyby wire.
Good fun though.

wear n tear I guess brought it cheap as is where is.
4th syncro well worn clutch at the end of its life..

flyby wire ? not so easy to mod fuel?

[jaza]

hey guys was trying to increase boost today and it wouldnt go over 10psi i put a gauge in etc and have a bleed out valve fitted it the right place wastegate to turbo wound screw preety much all the way out and wouldnt up the boost? any ideas
