1FZFE Turbo setup? (1 Viewer)

[BILT4ME]

But who's looking at mileage....It's ALL about the boost!

That could be a song....

It's all about that boost, 'bout that boost, 'bout that boost.....

 

[scottryana]

Here you go boss, real data from today. Moab to Grand Junction. About 2/3'ds at 75mph a 1/3 at 65mph.

Indicated 98.1 miles, GPS shows 109 miles. And 7.34gal to fill up so that's 14.85mpg. Surely could get 15mpg if I was running more than 30psi of tire pressure or I slowed down just a bit.

I have a snorkel, so I was hoping to retain factory air cleaner (back when the LX won Four Wheeler of the year in 96, they described it as "shaped like a trash can an only slightly smaller").

I was envisioning the air route as: Air Cleaner - Turbo - IC - Throttle Body. Would I leave the MAF sensor in the stock location or mount it between the IC and TB like was done here:

(No, I am not using the CX Racing kit, but it showed what I was trying to explain.)

Is the blow off valve going to give the MAF sensor fits?

Any recommendation for air-water IC? I was looking at something like this:

Running the stock air can is no problem it was done on Brett's truck when he did a turbo because he wanted to do a snorkel in the future. You will probably just have to modify the air can so that the intake is in a better place to suit the turbo inlet.

You can run either a pull or push through MAF you just need to be aware of how to handle either. If you do a pull through and leave the MAF in the stock location after the air can, you will just need to make sure that you use a recirculating blow off valve instead of one that vents to atmosphere and then vent the air tangentially to the MAF so that it doesn't blow backwards through it. Since you aren't going to be running huge pressure you won't be recirculating a lot of air and the amount of air you recirculate can be adjusted at the blow off to adjust any drivability issues. If you do a MAF after the IC that is usually fine too but you would probably end up having to mess with tubing sizes to get the engine happy. Since that air is compressed it isn't a true measure of the same amount of air in the stock MAF.

Both of those A/W Intercoolers work and would probably be fine. I tried the larger one on my build and am just not impressed with it's performance. If I were to do it again I would send the size drawing to Bell Intercoolers and have them make me one. It would probably cost 4 times as much but in the long run it would have saved me time and money. I think with a good sized turbo, and low boost you will be fine. Lilevo ran the smaller intercooler without a tank just a recirculating system and was fine.

Man, threads like this makes me want to do the 6psi turbo......but need to do HG first. Aarrgh.....too many projects.

Here a image of my basic system. Mild 6 psi, sucks gas for a reason!

Just as another hopefully helpful comparison ... yes I am 100% absolutely happy with my setup. Currently at 10.5 to 10.75 psi for about fifteen thousand miles now. Stock injectors, stock ECM, stock MAF, no piggyback. Rig currently has 198K and still pulling strong (turbo installed when rig was 75K miles). The secret is sizing of turbo and having adequate intercooling along with adequate exhaust ( I don't really think three inch exhaust is mandatory but it helps to have no worries with exhaust restriction). For fun I have had the turbo at 12 psi and it still is safe (borderline) as far as AFR's. The stock fuel setup in these rigs is really amazing so if setup of the turbo is good you're good. Hope that helps.

Is your MAF attached to the square air box, under the orange wrap?

Where are you guys sourcing the tubing for the charge air side of the turbo? Is it a universal diesel exhaust kits or from a online turbo shop?

I'm really liking Scotts list of parts. Would you recommend running a flex portion on the down pipe?

I'm thinking I might try do a setup.

 

[scottryana]

All of the tubing will need to be custom.

Intake to the turbo
charge from the turbo to the IC
IC to the TB

But should be very easy for any decent shop to knock out.

@turbocruiser

Is there a link that details the parts in your current set up?

If I understand correctly, you have had the turbo on for 125k?

 

[scottryana]

In his signature it lists the Safari turbo kit. It no longer exists.

I'll try to find stuff I saved a while ago but I think APS (Air Power Systems) has taken down the links to everything except their diesel systems now. As scottryana already shared they are not anymore producing their awesome "petrol" systems unfortunately. Yes the truck has had the turbo for approximately 125K miles! It was installed at around 75K and at that time boost was basically still at setting from factory of ~6.5psi. Over the miles the turbo has been boosted by about .5psi increments until it ultimately settled at around 10.5 - 10.75psi which is where I prefer it for safety's sake. My main points are that the stock fuel system is surprisingly adaptable, that a truly powerful and reliable turbo system is indeed perfectly possible (just to speak to the OP's thoughts that it is difficult to do both power and reliability) and that a turbo system can totally transform this vehicle. One thing that I'll post is a spec summary of the system set at 6.5psi I just happened to have saved in some file. If I find anything else that would help with someone's system I'll try to post it.

Power:
Standard = 158 kW (212 HP) vs.
Safari Turbo System = 240 kW (322 HP)

Torque:
Standard = 373 Nm (275 ftlb) vs.
Safari = 550 Nm (406 ftlb)

Maximum Speed
Overdrive off
Standard = 170 kph vs.
Safari = 190 kph

Overdrive on
Standard = 165 kph vs.
Safari = 210 kph

ACCELERATION
0 - 100 kph
Standard = 15.0 sec vs.
Safari = 7.5 sec

0 - 160 kph
Standard = 43.5 sec vs.
Safari = 22.5 sec

100 - 160 kph
Standard = 27.5 sec vs.
Safari = 13.0 sec

DISTANCE TO SPEED
0 - 160 kph
Standard = 1,200 m vs.
Safari = 650 m

HDJdreams Did you end up doing anything with this? After a longer (4400 mi) road trip pulling our little fiberglass camper, bikes, dogs, tools, etc. I've come to the realization that living/playing in the Rockies and driving at posted highway speed won't really happen without forced induction or a motor swap. And I do like me some turbos.

TurboFJ80 let's go run a trail sometime soon, and if you don't mind - let me take a closer look under that hood of yours. I've heard talks of Eagle Rock/Saran Wrap in the next couple weeks if that peaks your interest. Those shouldn't be too far of a drive for you.

 

[half k cruiser]

Does anybody know what turbo the safari system was running ? Are they using a small AA intercooler, J-pipe or log manifold ? When does the boost come on ?

 

[scottryana]

Log, A2A

 

[half k cruiser]

Log, A2A

Any idea on the turbo ?

 

[scottryana]

It was an old T3/T4 turbo with a custom housing, journal bearing, cast wheels. Pretty eh compared to today's turbos.

Boost comes on about 1700-1800 rpm. It gets into positive manifold pressure around 1900-2000 rpm, and can make full system pressure (4 psi) at around 2100-2200 rpm.
