Thanks guys!

I respect your opinion on the engine... although I never understood why it bothers people so much!?! I guess I could care less what engine is in a car. But I also stood along side my father, as a child, as he built dozens of street rods with what ever engine he felt like at the time. Some of my customers are actually the same way in that they want the same brand of speakers, head unit, amplifiers, subs etc. I have to explain to them that it's actually not a good idea. No single company makes the best in every category. So I hand pick the best of the best, in every category, within their budget. I follow the same thought process with my car. I don't care what brand or manufacturer it is... if it's good it's good.

How are u going to fill up the radiator?

I will be using a surge tank. You could also use a remote filler neck.

Damn.

Actually, your build has inspired me to get out in the garage from time to time. Hell, if we can keep inspiring each other we'll be unstoppable

I cant! I got caught up on a awkward moment trying to snap a pic during class, the prof called me out on using my phone. Her boyfriend who I was unaware of is now mad dogging me after class.

The reason I (and many others) don't like V8s is because of the impact they have had on drifting. To be competitive in FD anymore, you HAVE to have a V8, which dampens creativity and puts the emphasis on power instead of technique. The same thing happened to the WTCC back in the 60s, and if memory serves, it was in the 70s that they banned V8s and limited engines to 2 liters... That seems extreme in my opinion, and I don't really follow the WTCC, so I don't know what their guidelines are now, but I'm just saying this isn't the first time people have hated V8s in motorsports.

I know your car is not for drifting, and hopefully it will never see a track (it's too pretty for that kind of abuse) but the S chassis has become synonymous with drifting, so people make that connection automatically. It's almost like building an F1 car for show, sure it may never see a track, but it's still an F1 car.

...I do love your street rodder attitude!

Just do a BMW V8 or Viper V10! Bam you cover creativity and you compete. I know it's a cliche but "don't hate the player, hate the game". I think the reason drifting hasn't limited motor size is because it too limits creativity. Everyone would then be using SR or RB for the most part. I like seeing David vs Goliath.

Back on topic. The machined piece for the heater is awesome Toby. Local machine shop or your personal creation?

Yeah, that kind of sucks man... I see where you are coming from now. Too bad they can't have a range of displacement classes. 1) up to 2.5L 2) 2.6L - 4.0L 3) 4.1L +... or something to that affect. That would then get the creative juices flowing to get the most hp/tq out of your engine in it's respective class.

I designed it and a local shop machined it for me. Unfortunately I do not have a lathe or CNC.

See for a lot of us that we're into these cars before drifting, we feel the same way about drifting that you do about V8s in these cars. You say V8s have ruined drifting, where I (and many others) feel drifting has ruined the s-chassis scene.

Yeah, I'll give you that. I never meant that drifting being synonymous with 240s was a good thing... It's really not good for drifting or 240s.

[C. Anderson]

Looking clean Toby!

[kingkilburn]

The problems with engines in drifting comes when you have grassroots privateers going heads up with big professional teams. David and his 4ag hachiroku are going to have a hell of a time competing with Goliath and his TRD pushrod V8 RWD TC. There really needs to be a distinction between these completely different classes of vehicles.


And just to play devil's advocate to myself. A well setup off the shelf LS in an S chassis is not that different than any other well setup engine in an S chassis. The judges need to force the drivers to keep the speed up and stop the bullshit brake checking on lower powered cars.




/threadjack and long live the V8

[epik1]

Mr.Broadfield, amazing work. I think I'm developing an addiction to these s-chassis + lsx swaps like crackheads to crack lol. Just finished reading through 30 pages of bs jabbering and like 15 pgs of greatness :P

Over here in Toronto it's 11:11pm, and I need to start my essay now that's due tommorow, you win the "world's greatest distraction" award haha. Seriously though, amazing work! Will have to save up for an LS1/3 for my S14.

[newslidz]

V8S IN EVERYTHING! thats creativity. use it if you can make it fit. thats a challenge in its own. plus its more growth. there are now company's that can specialize in just that. and on top of all that its there when you need it and reliable.

[Darren]

nice Toby... good to see things are starting to get done..

Looks like everything's falling into place now

Can't wait to see the final product!

[marcs13r32]

wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!! love it

[CamryOnBronze]

Fittings on the firewall came out super nice, dude. Can't wait to see this thing on the road...

[smellslikecurry]

absolutely beautiful.

[1jzs14]

you sir are my hero!!!!!!! i just read this whole thing! its sick!

[Broadfield]

I got off my ass last night and finished the heater core setup. I cut the hard tubes down as far as I could and still allow me to get some 5/8" heater hose onto them securely.



As you can see I basically cut them down to the rib on the tube:



I then simply sanded down the tubes so they were basically smooth:



This is how they mate up to the backside of the machined bulkheads in the car:



Some simple heater hose and hose clamps... it's done. However, I will ditch those nasty hose clamps for the final install and use some XRP Ensure Clamps.





I also mocked up the radiator hoses:







I will be doing a surge tank for my high point in the coolant system. I will be running the steam ports into the top side of the tank, looping the output heater hose through the bottom of the tank and then into the front port on the water pump. Since I have never done a surge tank before, I do have one question if anyone can confirm it: do I absolutely need to run a port from the top side of the surge tank to the top of the radiator?

[smellslikecurry]

i love this thread. what size lines are you running for the radiator? i may have missed it before.

[Drift_This]

I believe he said they were -16. Car is comin together and looking good only half done

[Om1kron]

I would check with Stewart Leask about the ports Toby

Also thank you for being an innovator mentally on the same level as myself but with the means to actually put those orgasmic thoughts in your brain to use. Everyone is so quick to throw away the hvac like it's the enemy, as if they're eliminating a problem. HVAC is your friend, it will save your life on a cold cold night, and clear your windshield on a rainy day. Too many people ditch such a VITAL part of their cars and I think the weight loss that stems from it is minuscule and retarded. It will be nice to reverse engineer the work you have accomplished into my project when the time comes with less brain scratching on my part. I eventually will tear my dash out and have all of the electrical built from the ground up with Jeff's help eliminating any question as to what's going to what. All systems separate, but it's down that dark tunnel of priority modifications.

I'm totally on the ls bandwagon (for carb legal purposes) although my heart is with that peppy little 4 cylinder turbocharged motor. I think we've had our fun. Big plans call for big money so all I can do is save save save

There's no reason not to, that'll eliminate any chance of air caught in the radiator. Do you not have a filler neck? It'd be worth it to weld on a -4an male fitting to the top somewhere, Stew has a -4an on both sides of the radiator just in case.

Pratt & Miller (who build the C5.R and C6.R Vettes and Camaros) recommend plugging the rear two steam ports and running the front steam ports to your expansion tank ~ Dai (and Stew, who got the idea from Dai's car) run all four steam ports to the expansion tank. P&M said this isn't as good, I don't recall the actual reasoning, but it was all tested by them.

I read the same thing when I tore my LS2 apart. I touched the back steam ports were plugged and was about to unplug them for the expansion tank. The V8 Supercars only used the fronts. I forget the reasoning behind it. I believe it may "unequalize" the internal pressures if only 2 are used, forcing air to move. Or it could be the slight rake the motor has with the front sitting slightly taller than the rear. I'll stick with 2 for now.

Toby, the fittings look amazing. I need to get mine off to the welder to finish the water neck.

Cant wait for the end of this, truely beautiful!!

The surge tank will be the fill point/high point. I assumed I needed a line to the top of the radiator, but I didn't want to run one if it wasn't necessarily needed.... the less hose running everywhere the better. This isn't a full out track car like the one Scottie is building or a full out race car like Pratt & Miller build. So the requirements for those setups might not be required on my grocery getter... which is why I asked. I actually ordered the fittings last week to do the line to the radiator, but figured I would forgo it if not needed. Thanks for the advice guys, my assumptions were correct.

So since I will be running a line to the radiator, can I run it to the spot underneath the inlet port? Or does it really need to be level with the inlet port?

I believe that as long as the highest point of the surge tank is higher than the top of the radiator it doesn't really matter what level the line is at. Like if you put a straw in a cup that almost touches the bottom, you can still fill the cup through the straw.

[irritatedmax]

Rad hoses are rad.

Coming along great. I cant wait to hear this thing rip!
