An interesting note on the t3 new mfg rack, there are no grease points on either end for service.
-
@Zetsaz I had the t3 setup before so GC coilovers and Koni yellows. I ran multiple spring rates and configurations including pillow ball top hats. It was a really nice setup for all the years I had it. My buddy who had BCs actually bought my setup because the BCs ride terrible comparatively. The KWs imo are a few steps above the t3 setup and they're compression and rebound adjustable.
Tonight I finally had a few mins so I pulled the old rack and prepped the new one along with changing the ball joints at the front with some new moog units. I think I want to repaint the steering shaft but it's supposed to rain tomorrow so we'll see how the weekend goes.
-
@Zetsaz if you're ever in the bay area give ZCG a call and see if you can try the setup on their shop car. The full package is really impressive tbh from the KWs, Rebello stroker, stoptech brakes etc. Well worth the wait. Rob is a great guy and experienced driver driver.
@AydinZ71 thanks still weighing swain versus full inconel shielding again. I think I need to see how the clearances turn out with the cnc manifold first and go from there.
This past week or two I've been working a lot but it looks like I finally have some time this weekend to get back to the build. At least a few hours. Hopefully some updates soon.
-
Thanks @Zetsaz yeah it's been a long time coming, I really liked the feel driving the ZCG shop car over the t3 BBK setup personally with both the 1" and 15/16 MCs I had before. I'm downsizing everything but I think it'll be the right balance for my needs.
More parts came in today including the t3 rack and high clearance tie rod ends. I owe a bunch of people measurements at this point to keep things moving forward on some design and machining work so that will be the priority this weekend.
-
Have a lot going on and I realize my workspace is an absolute mess. It's been a while and there are parts and tools scattered about so I think the strategy here is to clean everything up this next couple of weeks while doing these sidebar projects to get the car sorted.
-
Parts are still slowly trickling in. My ZCG Stoptech brake kit came in so I can hopefully finish reassembly of the new suspension and brakes.
The first test print for the cnc 50 manifold came in as well. I'm really excited for this manifold project, I think it'll be the perfect high clearance dcoe manifold. Fortunately I have both a spare engine on the stand and also a blowthrough s30 to test real world clearances on 😁

@tube80z thank you got it working

@Sean 83ZXT for my setup, I wanted the highest response setup with a powerband between 3-7k running at 15-21psi (OER/SK carbs can do ~16psi constant and 21+psi intermittent). I had also looked at the g30-770 but the 660 won out for my goals.
ATP advised that the newer aero on the G series turbine wheel will flow enough to keep backpressure in check on the large 3.2L up to 7K without choking up but the key is to mate it to the .83 A/R housing. Also noted that on the g30 the 660 comp wheel is the most boost responsive configuration that is capable of providing the right amount of airflow
for those required boost levels. -
@DuffyMahoney yes the step up will be necessary to clear the turbo and manifold. I assume the HKS v2 surge tank was designed with the s130 in mind as fitting everything into the s30 poses some interesting challenges. Likely the cnc option would be between the Mik short runner and the FET mid, combining the best of both.
@rossman after playing with boost adviser and staring at compressor maps for a while I narrowed it down to the g30-660 or 770. After discussing with ATP turbo I went with the g30-660, as it sounded like a good match we'll see how it goes.
@AydinZ71 I looked at the g25 too but it seemed too small for the 3.2 8.5:1, perhaps it would be a good match for the l28ET. Post some pictures of the swain coating when you get it back, that sounds pretty sweet. I was considering that this time around but ATP inconel is on the table again as well.

Clearance issues aside this is looking pretty sweet. You're one of the first I've seen running the newer G series turbo on an L engine, much less one with carbs.
Yeah I'm stoked to get this setup together! I suspect the 0.83ar will spool like the old .63 and provide a lot more.
8 hours ago, DuffyMahoney said:Fet V1 for the win! Still waiting on mine
The v1 is really awesome. I wish there was a vintage option that checks all the boxes, but after some news today I may go with a custom billet cnc option. Mikuni length with proper clearance and porting for 50s.
-
More mockup work with the new turbo setup.
It would be pretty sweet if I can run this FET manifold, the clearances are actually pretty good. Perhaps if I machined a bit off the DCOE flange side. The downside to this manifold is it's pretty thin walled, so porting for 50s may require welding.
Either way I can already see I will need to cut and weld the inlet on the new G series like I did with the old hybrid turbo.
-
More mockup work on the #s matching spare motor.
From past measuring I know the Harada/Kameari, Nissan Comp, etc. long runner manifolds put the v2 surge tank into the s30 shock tower so those were non starters.
The Mikuni short runner will definitely need to be modified to clear the PTZ manifold for runners 3&4.
The FET mid runner clears all but may be right at the shock tower.
Also exploring a custom CNC manifold option.
This is probably super niche but maybe someone can find this useful, I know I could've used this info yrs ago
-
To get a better idea of what modifications may be required, I compared 2 spare mid/short runner manifolds I have.
The vintage Mikuni which is the shortest to my knowledge may require modifying runners 3 and/or 4. The vintage FET is mid length and may have just enough rise and run to clear, but I'll need to see if it puts the surge tank into the shock tower.
-
Still some delays, but parts are slowly trickling in.
Pro TunerZ produced a custom manifold and downpipe for me, to run a Garrett G30-660 vband turbo. Huge shout out to Hussein on that, the workmanship is great.
Once I get my 50s set up then I'll need to mock everything up on the car again and clearance or modify as necessary before heat shielding.
-
It's been a while but I'm still working on things in the background. Mostly I've been parts delayed but there should be several major components coming in this next week or two.
Protunerz finished fabrication of my custom vband manifold and DP so that should be in soon and hopefully my Z Car Garage brakes will be in later this month.
Tonight I started tearing back into the motor. I have some quick business to tend to in SoCal around Sept so hopefully if all of the parts and timing lines up I can get everything mocked up on the motor and drive the turbo setup down to ATP for inconel shielding.
-
Did they paint it in the prep bay with all of the trim on it? Just constructive feedback but I'm surprised you paid to paint it like that after you spent so many hours painting it in your garage. It's only a few hours to pull the trim and glass, certainly less than a day.

I thought I heard about them going out of business? Who else make a plenum that is available to purchase for the L-Series motor?
Apparently you can pre-order them here: https://milkfab-engineering.com/shop/ols/products/milkfab-l6-ultimate-intake-manifold?fbclid=IwAR2QU6NWyno4bkaHjMeclJE8GjibiUpXNflrK7zKtNn78XIMtKwqNsuRALg
It would've been cool if they had a standard dcoe style pattern for the runners to open up itb options.
Also I just realized in the description you inspired the design so I suppose that makes sense 😅
-
That plenum is a work of art. Have you seen the Milkfab engineering plenum? It looks like they're working on something similar, but I think your design looks much cleaner.
-
Looking forward to it and welcome back!
-
Your car looks really straight but was it ever in an accident or are the moustache bar studs off on the chassis? That spacing to the spare tire well looks really tight. I would think others with the same setup would be complaining about that.
Did you ask T3 about what's going on?
-
Also before I forget huge shoutout to Harold Burroughs @ https://www.stuffharrydoes.com/
He fabricated me some reinforced engine mount brackets which will allow me to fine tune the angle and tilt of the engine.
In my case I want to optimize the balance between the required carb angles and height/tilt of the engine to get more clearance for a strut bar or whatever bracing will eventually go in the front.
-
Just some quick updates, the build has been going on in the background. Life has been busy so I've only been able to put a couple hrs here and there. Still waiting for parts, mainly the ZCG stoptech brakes.
I'm also getting a tubular manifold and DP set up for a Garrett G30-660 0.83a/r turbo and Tial MVR 44 wastgate. Originally when I went with the t3/t4oe hybrid I thought I was going to be doing a l25/l28, but then life resulted in the 3.2 instead. Once that gets in I'll check clearances then off for inconel shielding again.
The new turbo tech should provide better response/spool even with the larger sizing and it is also all vband in/out so hopefully the hardware stretch issues I had before won't be an issue anymore.

Nice change of pace today, got up at my normal time which is way too early and got the new rack situated. I think I need to get back into the routine of putting an hr into the build every AM. Did some measuring as well between the exhaust and new DP and I don't think I'll need to order any more pipe but I'll need to order another vband flange from Vibrant.
