Garrett .42/48 for 4.0

[fishy2k8]

Well I've seen a couple v8 guys do this. How about a log header for the passenger side with the drivers side connection to the back of it and the front having a mount for the turbo? I could easily make the header myself and that would give me room for the downpipe and everything. What u think?

If you can fabricate it then yes that will be fine. Just make sure you build things beefy enough to support the weight of the turbo hanging off of it. It needs to handle the weight of the turbo itself and also resist the ability to crack during heat/cooling expansion and contraction while that weight is resting on it. So cliffnotes...Yes...But build it real beefy or build it fairly strong and make a bracket that supports the weight of the turbo off of the engine independent of the passenger side log manifold. This will take some time and be more expensive.

Another option that would be similar would be for you to reuse your stock cast iron manifolds and just build a crossover pipe with s.s. flex connector from drivers side to passenger side, flip the passenger side cast iron manifold so flange faces forward, and make an adapter that fits onto passenger side manifold and also allows driver side pipe to connect to it with a V-band clamp and then route to turbo from there. The advantage to this is that it is cheaper, faster, and the cast iron retains heat energy much better, and the cast iron is stronger than steel or s.s. tubing is. I am not a pro with the 4.0 OHV engines so one major thing to check to see if this is doable is seeing if the bolt pattern on your passenger side exhaust manifold is conducive to flipping it around and mounting it with flange facing forward. One other thing to check will be where that flange will end up pointing after the flip. Does it point directly at an accessory where you cannot fit an adapter pipe in there of is there room to use? If I were doing a build like this those would be the first two things I would check to verify whether I could do the cast iron manifold flip or not. Good luck.

yeah i agree, im going to start looking at it closer and playing with ideas.

here's an idea im currently playing with. I've got this little turbo up on the local craigslist. ive had a couple hits of it already, got it up to make a profit (for sale for $110). I've got a couple people who are good at sourcing good factory TurboCoupe .63/.60 turbos and rebuilding them. for about $200-$300 i could have a rebuilt, correctly sized turbo with either no internal gate, or a gate with a removable actuator that i could then swap with a 5lb spring actuator. i admit the little turbo was an impulse buy haha, but no harm done.

what is your fella's take on this?

as far as mounting the turbo.. i've got a couple ideas floating around that i think may work, but need to see what kind of room i've really got.

oo.. and here's my baseline hp, got the truck dyno'd today and my current tune straightened out for the motors mods i've already done. also got a boost tune for 42lb injectors and the slot maf blow through setup.

the tune i was running had a half-a$$ auto tranny delete on it, which caused it pull timing and advance timing for torque load junk that it doesn't need for manuals. won't mention names of who previously tuned it, but it's all taken care of now

here's what we got:

191.2rwhp/255.5rwtq

That sounds like a good plan you got there. Wow 190rwhp out of the 4.0 OHV is not bad at all. What exactly has your shortblock been built with parts-wise?

 

[Jakee]

I like the torque line. (notice I didn't say curve)

And I was a little worried about you running the higher compression and a turbo that would be heating up the air. It seemed like a recipe for detonation.

 

[fishy2k8]

yeah i rather have something more efficient than that small turbo cause ur right it's gunna heat up...

how about this?

t-62 model turbonetics turbo charger..t3/t4 housing with .48 a/r exhaust housing

 

[fishy2k8]

bottom end is stock from a 94. the heads are ported 98TM Alabama heads with 3 angle valve job and ss valves (older bottom end and new heads gives the 10:1 compression ratio).

cam is comp 422, with delta rockers modified to be free floating and correctly length pushrods

ported intakes, bbk 66mm throttle body, headman headers, the 30lb injectors, and stock maf

 

[fishy2k8]

what are your guy's thoughts on a turbo for ~$200-$300. are the on3 turbos any good? they make a bunch of mustang kits and a bunch of people run them so i'm assuming they aren't too bad.

 

[Jakee]

I have a bud that bought an e-bay turbo and it's holding up. I would say it's an option; get the correct size and go for it. And if it doesn't last forever then you could upgrade.


Not sure about the t62. Maybe rocket will run the numbers for you.

 

[fishy2k8]

turbonetics T-13054 is the serial/model number.

with the .48 a/r exhaust housing i should be better as far as not idling in boost hahahaha but still get a nice quick spool right?

 

[fishy2k8]

any input on this turbonetics im looking at?

 

[fishy2k8]

so im looking to run 60lb injectors and e85. and this turbonetics t62

Don't know much about it but from what I see there are water ports. So I'm guessing this has ball-bearings and not journal bearings?

 

[fishy2k8]

no it's got journal bearings. the water ports are for cooling the turbo more.. you can use them and you can not. lots of factory cars have coolant and oil cooled turbos. the water coolant eliminates any need for a turbo timer basically

Water ports do not equal BB CHRA on a turbo. Those little T25's that I am selling have water ports in them too but are just a typical JB.

 

[fishy2k8]

hey rocket, you mind mapping out that turbonetics for me? it's the stage 3 turbine, .62 compressor, .48 turbine, 60 trim

I do not have any turbonetics compressor maps. But if you get your hands on the right one then post it and I can map it for you.

 

[fishy2k8]

what you guys think about just running the turbo off the passenger side? then connecting the drives side exhaust into the downpipe of the turbo? that a bad idea? im thinking this might give me a bit longer spool which ill probably want with the smaller hotside without getting a bigger one.

thoughts?

Don't think it's a good idea.
