I have been itching for a kit thinking it will awaken the 1FZ. Has anyone seen this? I don't recall anyone discussing this kit.
Thank you for the reply. It would be idiotic to take a machine with the dependability and reliability of Old Faithful, bolt garbage to the motor and expect the same reliability and dependability. Gains+reliability otherwise we'd be driving a Jeep.That's the CX racing kit. Its been discussed lots of times. The manifold might be decent, or it might not, the rest is cheaply made ebay/Chinese parts. I have not seen anyone on here do any comprehensive review on it. I think where @scottryana is going with his idea is to have reasonable power gains, but use only quality components. You are essentially paying more for better peace of mind and longevity.
Yeah this would be a great solution. Looking at a rebuild soon and am considering the 5.3 vortex swap. I really like the 1fz but the lack of power in the sierra while climbing hills is super frustrating. Nothing like being stuck in the semi-truck line on Hwy 80! How feasible would it be to reverse this for a smog inspection![]()
Also, is there a internally wastegated turbo that could be used for this setup? Is there a reason other than availability that an internal wastegate wouldn't be used?
Borg Warner doesn't make an internally gated turbo for the right size for under $2200. The cheapest Garrett GT35 you can get with an internal gate is $1600 or so, so the cost of the kit would go up a lot, even when you subtract the cost of a Tial wastegate.
I have been looking into a Holset hx40 or he351cw for an internally gated turbo at a fair price, but the exhaust discharge would need to be modified (aka welding on the housing) since there's no way a 4" dodge brodozer downpipe is going to fit through the little hole between the inner fender and the frame.
:edit: external WG also does a better job of regulating boost, but IMO the packaging benefits of internal WG outweigh that benefit. As long as you're in the right ballpark, I think it would be OK.
Does anyone make an aftermarket VG tur
Is anyone using and/or do any companies make an aftermarket VG turbo? The heavy and medium duty diesels I work on use them all the time. I realize it would add cost and complexity but it's hard to beat for controlling max boost as well as when it starts building boost.All very true except I am not sure you can say External Gates regulate boost better. It absolutely depends on the design of the turbo manifold, the size of the wastegate, if the exhaust flow is directed to the wastegate or if the gate is 90* to flow, etc. While the Internal Wastegate are absolutely in the flow of exhaust. The big difference with internal and external gates is that the internal takes 3x more time and effort to tune. Because they have less adjustability and you have to swap wastegate canisters to effectively make large changes. While the external gate its a little easier.

The diesels I work on red line at 1800-2200 rpmsAnswered in the post above. With such a narrow useable RPM range for a turbo gas the VG is really just more to go wrong.

I knew I wasn't seeing the whole picture...the torque converter! All of the engines I work on are manualsYep that is why you need boost to start as soon as possible. SO you have to adjust the vanes to catch as much of the small amount of exhaust gas, it wouldn't matter if you did that with our engines because the torque converter stall doesn't change.
It's a vortec swap or just live with the stock HP for us Cali folk. Too bad...this seems like it will be quite impressive.![]()
