Not saying that it means nothing that he is a Garrett engineer.

We also said basically the same thing... material does not matter as much as design and shape. What I added were some of the advantages of it being billet with the added ability to change the design to be better, easier.

What I will add is that the influence of "billet" gets grossly over-inflated in marketing and bench racing.

I'd wager that almost all of the high-flowing billet wheels on the market could indeed be produced via casting.

I think the main issue is capital investment. If you're running a turbo rebuild shop or a small turbo manufacuring company, you can certainly design a wheel in CAD if you want to, but the cost to tool up a casting with that geometry would be a huge barrier. Much cheaper to go fully machined, which allows you to make quick changes as well, and not commit to amortizing six-figure investments over thousands and thousands of pieces.

It's true that a forged, fully machined aluminum part will typically have better material properties than a casting. I'm just saying take a step back and think about the decisions being made vs. the words being said...

Could not agree more. Very much a bling term.

Back to the regularly scheduled programming!
End thread jack!

What happened here lol. Starting turbo swap mayhem this weekend if all goes well! Gotta yank the engine out of my 245 because it decided to spontaneously leak from everywhere

[cosbySweater]

Well pulled the engine out of my wagon and power washed the engine bay. Have some exciting news about the 244 that I don't really want let out just yet. I fitted a turck intake and found it cleared perfectly. So the car is going to get a tbss intake along with new fuel rails, contemplating on doing a big 92mm tb or just rocking stock tb with a adapter. I dunno yet but my plan is to maximize efficiency.



Also hot rid of the dog**** analog aem and threw a normal digital aem in it. I've been driving with no afr gauge for way longer then I should have



Looks out of place, but whatever, at least it works

[Jack]

You better be featured on some show

[cosbySweater]

Got the tbss intake test fitted. Had to cut all the hood support out of it to fit it and that's fine with me. Trimmed a bit off the front of the manifold and put on the dbw TB on it to test fit. The dbw stuff did not fit at all. So I cut it up to check for clearance. Got to a point where the hood would make no contact and have some wiggle room. So I did some research and found that fitech makes a sweet throttle body that's lower profile then any other throttle body I could find. Another idea was to get 2 4 bolt flanges and make a extension and angle it downward but I feel like this TB should work. The China tbs have a massive chunk of aluminum up top that will for sure not clear at all. They look just like the Holley (which is most likely a rebranded China TB) any way. I love the way the tbss manifold looks compared to the ls1 intake.




Here's the fitech TB.


And here's the Holley/China TB


Hope this helps some people looking to do the swap!

Alright so in the middle of screwing around with the fuel system and intake for the car, I have the intake ready to drop in. Just finished up fuel rail mounts for it yesterday, the new fuel system setup is going to be -10an feed line from dual aem 380lph pumps to the rail. I'm going to over do the whole fuel system just because I'll have more overhead with it. Also have some 210 injectors I'm going to be using on it. The throttle body is a nice piece. So hopefully I'll be able to get some work done on it this weekend.

[cosbySweater]

It's finished, except for the return line :/. Came out great, need to retune the car tomorrow!

[cosbySweater]

well just been driving the car and tuning, cant get very far, completely out of fuel pump at this point. so I hope I can get that fixed and do some drag racing before the end of the season, started working on some other stuff including the 55. we started to rip into the engine and figure out what we are going to do with it. the chassis is done so body and drivetrain are whats going to start happening soon. so once the volvo is settled this will be getting my full attention.

[Pillow]

Lookin good on the TBSS intake! Also neat mount for the Lokar cable!

The shoebox brings back memories. My first car was a 210 55. 'Course, that was 47 years ago. Mine had the covered wagon suspension. ;)

Wasn't there an old Hot Rod Magazine feature about a Nova on 'Vette suspenders called the No-Vette? This ought to be fun.

Reckon that would make this one a Chevette. Wait a minute....

[cosbySweater]

Yeah the 55 should be fun. It's not going to be a show car, going to throw on used trim and probably wrap it after the body work, I'll try to throw some engine pictures up later. The original plan was to twin turbo it. But it's going to be n/a for simplicity. My dad is working on building some itb manifolds for it now that he is later going to have cnc'd

[Texas240]

Nice use of the C4 rear end. I look forward to put the 92 I have into my wagon

[cosbySweater]

Yeah my dad helped develop these chassis in the early 90s he's been using these since I can remember. I remember when the c4s we're still new and I thought they were the coolest cars ever and I would point them out. He would always say, "those are just parts cars" little did he know in 2018 he would be daily driving a 1990 zr1

Nice. Its such a simple setup that works very well for its purpose

[cosbySweater]

No real updates just yet but I am still doing alot of work to it. I'll post when it's done. For now

[122power]

Woo nascar burnout

[cosbySweater]

Well, going racing this weekend! Installed a 25mm sway bar in the rear and threw a stocker back in the front. Remover the exhaust before the axle and did a turn down to clear everything. It's so loud but sounds fantastic

[gsellstr]

Let me know Erik. I've got plans in the evening, might be free in the morning, wagon is still running solid. Chance of rain though so who knows.

Now if I can kick this cold...

[cosbySweater]

Chance of rain Saturday??? Damn I'm gonna have to keep a eye on that

[cosbySweater]

Whelp got the fuel system done. Ended up going with twin 525 pumps in the stock sump. Welded in another stock sending unit hole offset for fuel level. Which I might add hasn't worked in over a year. I'm returning through the sending unit and straight feed off the sump. I'm running 5/8 pfte steel braided lines to the rail now. I'm using Ms to trigger a standard bosch relay which triggers a 80amp stinger relay. The power is fed off the alternator and 8g wire to the the pumps. Relay and pumps are grounded off the negative terminal of the battery

[stevE85]

What power level are you looking to achieve with all of this? Were you fuel limited before?
