4JB1T Compound turbo setup

Postby paulthepilot5 » Wed Mar 20, 2019 8:25 pm

Hi Guys.

Just about completed my compound setup on the Rodeo. Will soon be upgrading pump to a 12mm to make the most of the setup.

What turbo is your high pressure turbo? The low pressure looks to be a gt2554, how much hp you going for?

Low pressure is GT2871r high pressure is a TD04. Hp aim is as high as possible. Was just shy of 200hp on the last setup with single turbo. Would have gotten more out of the single, but was working a single turbo way too hard.

Cant wait to hear how it does. I opted for the Borg Warner efr7163 for the low pressure, but i wanted a clean 18:1 afr. High pressure is bit of a hybrid lol. Those td04’s are good turbos, should be a solid setup!

Yeah the TD04’s are good, had the last one running 35psi every day. At this stage the compound setup is running ok. Builds up about 47psi boost at the moment. Re doing some of the pipe work at the moment to improve flow flow from the high pressure wastegate. With the added fuel from a 12mm should be a pretty angry setup. Have a three different trim td04’s to try on it as well

Got some of the pre compound setup, when it was running 14.8 sec

Don’t think I will get it any quicker times until I can get more fuel into it.

So after the crank snapping incident I have almost finished building my spare engine. Crank may have had an issue due to a loose harmonic balancer about 6 months ago, this may have caused damage at the time.Anyway, have upgraded crank and a few other things including camshaft. 12mm pump is on its way as well. Also going to run the larger TD04HL-19t for the high pressure turbo, (original one was a TD04L-19t)

Excellent craftsmanship and quality. You did a great job making sure things were built with purpose, from the Wastegate outlet merging on an angle, to the bellows for stress free expansion, well done! Also love the v band, makes removal/ installation alot quicker.

Thanks for that. Took a bit of mocking up to get right and a few things were just a luck. (like still being able to take the rocker cover off. The atmospheric turbo can be removed in about 10mins, makes access to everything else a lot easier. Was quite difficult to get coolant and oil hoses running nicely and keeping them from contacting exhaust components. So I’m going to do all the coolant lines in 3/8 alloy hard line with AN fittings, 1/4 hard line for oil supply. These will go from some distribution blocks for both coolant and oil. Have to make up some 3/4 R14 stainless/Teflon lines for the oil drains, going to another block bolted to the dump in place of the factory drain.
