Rear mount turbo questions

hulet1006 · 12-23-2018, 07:27 PM

I’m building my own rear mount, and I’m not finding any pics of how the intercooler piping is routed from turbo to intercooler.

Also what size exhaust to the turbo is everyone running, and what size piping to intercooler?

As far as I've seen, the people that built rear mount turbo systems have been pretty exclusively posted on facebook. Hit up Luis Garza, he can put you in the right direction. He had one of the first DIY builds for rear mounts.

They aren't on here because they just don't work that well. Save your coin and buy a quality kit. There are several good choices out there. The next thing to consider is all of the supporting mods that are needed so the engine can stay together.

They make power, but are very inefficient (lag is freaking crazy and the powerband is small.

Sounds like you guys have never had a proper rear mount before. Lag is negligible as long as it’s done right, and they can make great power. Even with supporting mods, I’ll be under $4k for everything.

Spooler · 12-25-2018, 07:26 PM

No we save 3-6k more and get a high quality kit. Nobody installs that junk on here.

Hardly. I have way more than $4k just in supporting mods.

It’s the boost threshold that’s the major concern.

Yeap, the turbo kit is the cheapest part of the build.

“Proper rear mount “ that all depends on your goals/build/expectations ... if you looking for 400ish whp with less lag you will need a smaller turbo which will lose top end if you want more top end then you increase the lag severely ....you can make a base level turbo kit but no real room for growth

If you dropping 4K you would be better off saving for the Boosted performance kit .... 10k for kit and supporting mods 600hp all day long

I hear people have some kind of success with these things, but I've never seen it. It doesn't make a ton of sense from a physics perspective.

TopgunZ · 12-25-2018, 10:30 PM

The guys on the LS forums love these and are making insane power and 9 second cars all day. Granted they have much more displacement. But a proper sized turbo for this platform has a chance. I say do it.

Keep the exhaust piping small. You want velocity and wrap it all good to keep the heat high. The big 370ci guys go 2.5 inch charge piping to intercooler so go that or even smaller.

As a starting point, take a look at the 350z sts kits and see how they did it.

Elmo370z · 12-26-2018, 01:12 AM

RZG rear mounts makes really good power, There are 350 Z is fast as hell but doesn’t start making boost until somewhere close to 6k. Inefficient (lag) only good for straight line roll racing.
