Hey Rob, the gasket might give you the clearance you need on that turbo. Try fitting the turbo on with the gasket installed.

[@rexrunner]

𝐓𝐡𝐞𝐑𝐞𝐝𝐑𝐚𝐯𝐞𝐧 better off just using an extra flange as a spacer.

[@markhutchinson3367]

As a person that worked at a turbocharger manufacturer for 8 years, that turbine housing you put on with the larger gap will definitely have a large affect on spool. For the highest efficiency, you want the face clearance of the turbine wheel to contour of the turbine housing to be around .020" to .030" total gap. You can measure with pin gages or feeler gauges to see the gap between the blade of the turbine wheel to the housing, it should be around .010" to .015" (which is the previously mentioned .020" to .030" total clearance, divided by 2 since you're only checking one side of the housing). I can see just by eyeballing it from your video that your size is far out of the range of tolerance. You're probably looking at .050" per side gap (.100" total) if not more, which will make that turbo spool at least 1000 rpm later or more and also affect peak hp/tq. It seems that the new housing you bought is the wrong trim size for the turbine wheel you have.

[@RobDahm]

Appreciate the feedback. First thing I noticed. But I don’t have experience like that. I’ll message ATP about it.

[@markhutchinson3367]

@@RobDahm No worries! It is a risk when you mix different manufacturer housings, seen it many times over the years. Each manufacturer has their own tolerances, Garrett is toward the tighter side, tighter the better (that's what he said) as the efficiency is at it's greatest. Your situation looks more like perhaps ATP shipped you the wrong trim size for the turbine wheel size though. Hopefully they can get it sorted for you. You may have to ship the turbo to them so they can properly match the housing trim size and may need to do some machining to get it just right. Looking forward to seeing the car done!

Hey Rob, have u thought about grinding the side of the leaf spring up front, along the side of it. U can keep the same thickness of spring, but make it have less force against the control arm without making it weak. Could be a easy option to make it the correct ride height, also quick and cheap for stock springs u can modify for whatever engine your using. I love your channel and watching you show us real time builds. You have been the main influence on me starting my hot rod and trying to film it for KZbin. I have lost some footage of the build this week, but hope to get someone to film for me and keep updates. Thank u, and look forward to Future videos.

[@Brock_Landers]

I realize that we're talking about apples and oranges, but I have a Garrett GT3582R dual ball bearing turbo on my built LSVTEC in my EJ8 Civic coupe and I just made 588 whp on 22 psi. I know how much air the rotary pushes out, so you can spool a 1.06 AR housing turbo much quicker than I can with my piston engine, but that should be an awesome turbo for the 13B and make some crazy numbers. I have to say that I have NEVER seen this attempted, or even thought about, so I am pumped to see what the outcome is and how well this combo responds in this chassis.

[@LexJones]

You should totally route the airflow for the intercooler through the hood, like you see with some mid engine car's, you've got the space for it.

[@leetucker5788]

Rob, check that your turbine housing is correct for the size wheel on your turbo. It might be for a slightly larger one.

[@buttsexxor]

re, the gap in the turbine blades, yes, there will be a slight loss of 'spool' pressure as the gas bypasses around the blade edge, HOWEVER, this leakage will be compensated for very quickly and exceeded once the wastegate begins to open. In practical terms, the turbo would be a very tiny bit more sluggish at low power, low load and low RPM conditions, but in reality, you wont even feel the difference.

[@citystar87]

@@simontimperley802 its more of a rotary support comment. I get it. The ls is great. But so tired of LS swaps in place of rotary in rx7s, rx7 and rotory should be something people fall in love with because of the history, heritage, and the ability to be different. I think rotary can easily out perform an ls, but it obviously takes more work. Like owning my datsun. Its about the passion for the vehicle and where it came from and what it was, im not putting a 2jz in it or a LS in it, id rather appreciate owning the L20 in it with its issues and luxuries because its not the other motors that can be put in that are better, a popular swap is a vg35, or vq motor, but to me that takes passion away from owning the vehicle. I dislike american muscle guys buying an rx7 because its not what their normal american muscle friends or them have owned, then just swapping in an ls. Like whats the point.
