Bigger turbo and bigger boost area by way of turbo piping running from the back. And he runs all the boost. Definitely gains to be had by the replacement intake when not going to the extreme. And I was pretty sure it was using coils not stock ignition.
Astra electric power steering pump will not disappoint and then run the turbo header over the alternator. Will end up better for everything involved imo. Also a custom made plenum top rear entry style would look sexy!
I was coming here to suggest an Astra electric pump, and that I can send you the one I have as I am not using it, as I have decided to go EPAS from a Kia Cerato. However, after reading all the comments I see that you are not keen on the Astra pumps due to the noise and current draw. Maybe look into an EPAS rack conversion or even on the column? Would be a great conversion to do, and show the viewers that you don't need to spend megabucks on getting EPAS to work. As for "Scotty is not a teenager anymore" when you were thinking about pulling the drivers seat out to get access to the booster, I know where you are coming from mate!!!! I've got just under 6 months to go before I hit the big six oh, getting up and down off the floor when working on cars ain't as easy as it used to be!! Keep the great content flowing, and the double entendre and dad jokes coming!!!
Scotty. Just do the astra pump for power steering also i ran LS1 coils with custom leads instead, easy to get to plugs in it. Also the why i ran K frame spacers so that intake could fit under the bonnet. ITs alot of work the old 1uz in commdore.
The old extendable radio antennas are the best thing to check bonnet clearance - clamp em where you wanna measure clearances in the enginebay, close bonnet and then measure the retracted length
Hey Scotty, Al and Woody have used Subaru boosters on a few projects as they are smaller diameter. What about old school HT leads and remote coils. It won't look as pretty, but there will be more clearance and there won't be a problem with the power goals you have. Also could you lower the mounts and/or notch the K frame to get more clearance with the bonnet etc?
Hey Scotty had a similar problem putting an LS1 in a Porsche 944 , the solution was hydroboost . Great braking boost powered from your power steer pump .Brett
My old man passed a few years back and there's a pretty mint unaltered 944 in the garage. How does one go about installing a LS1. I have heard of LS swapped 944's but have no idea of what's involved. Any fab work needed or any really special or is it pretty straight forward and then throw a haltec ecu at it?
When you have got the manifold / plenum, spray them in red crinkle paint. Then polish up the high points, and the Toyota symbol and stakes on the plenum.
You could use that Holley plenum that you already have flipped around with a modified 90deg bend on it for the throttle body. The brake booster might still be in the way though.
hey scotty, maybe you could run a remote booster like a older land rover, hide it under the driverside guard similar to the evap ball thing on the passenger side
grate work 👌👌I run a single turbo 1uz get rid of the power steering pump and run a electric pump will give you heaps of room and will drive like a dream I run my pump in the boot works perfectly.. grate build 👌👌
There was 1 particular HK/T/G booster that was smaller in diameter as you have noted. It was also used on the XU1 & A9X. HDT also used the dual diaphragm version of this on the 5.6L stroker cars, like my Brock wagon, as they produced more boost from less vacuum than the VK/VL boosters. At 9” diaphragm diameter, it is significantly smaller in diameter than the original HQ-WB boosters Holden used which are 11”. I did some checking, and the VB-VR boosters are 9” as well, so this won’t help Scotty unfortunately. Watching the video part way through, I was thinking the shallower plastic VS one might have been short enough to clear, but turns out it wasn’t. No point trying the VT onwards ones - they are almost as big in diameter where it matters for that coil. The hard part with any replacement booster is having the right fit-up orientation for the master cylinder, so you can retain it (and avoid many hassles with engineering, and having to fit bias adjusters and other crap if you can’t find a master cylinder that matches the original front & rear bore sizes). This was where HDT were clever, as that “special” booster only needed a custom firewall bracket, and took the normal VL 1” master. While there are a myriad of smaller diameter booster options out there, most, if not all, won’t be an easy fit without numerous other changes.
Relocate the battery Astra Powersteering Pump where the battery goes. Maybe mill/machine some of the deck height from the intake runners on the engine side and from the under plenum to lower the profile? Can you relocate the brake booster to the passenger side, Im sure I remember seeing something to do with bmw and relocation of the booster
Are you able to flip the driver's side manifold and run a rear crossover pipe? Will solve the alternator/powersteering clearance issue, aswell as keep some of the hot piping away from the inlet side of the engine bay. Good to see the stock intake manifold back on there, certainly isnt going to hold you back any whatsoever, the juice simply wasnt worth the squeeze in this case for aesthetics.
I think the standard looks better scotty. You can always run a carbide through the runners and open them up.. We've always played the game of MM.. it's not fun..😅
Been watching HOME BUILT BY JEFF? he pulled the Ferrari V8 from his 105 Alfa a HEAP of times to set everything up, epic build if you like this kind of build. loving this Lexen build and combo
Mate Scotty its a VR/VS cut the bonnet, put a small hole in it that's it leave it open so even more cold air gets in the engine bay and intake ? Or cut the inner bracing on the bonnet to make room if its in the way, plus adjust the rear part of the bonnet to lift it up as well, like old school lifting the rear areas of the bonnet etc?🙌🙌✌✌👍👍😀😀
Looks like Scotty will be doing some custom bspoke exhaust and intake welding cutting and fun and a smaller booster heard Gemini ones are smaller maybe Subaru
You might have some luck using a Toyota Hiace brake booster Scotty. I heard they are pretty compact for the van application so they might be a good solution here. Bonus points for more Toyota parts too 😃
Run coil leads off the spark plugs to ls coils, get the car running NA first then turbo it, stock header on the drivers side merged into a single header on the passo side or long tube headers and a remote turbo under the back seat
Can you not use an electric PAS system? You boys have the Barina, which is the same as our Corsa and they had a column driven PAS system, very common upgrade or mod for older cars.
You could always consider having a top made and maybe scallop the lower section and recess the throttle body lower into the lower section using the neck from the standard manifold then make a top section. Or just leave the standard one on.😮
Hey Scotty, Maddat sell custom small can brake boosters and do a range of master cylinders to suit if you truly get stuck. Love ya work. Keep on keeping on 👍
Sorry Scotty, Just watched the rest of your video and my suggestion was answered. Just for your info I have twin turbo 1UZ into VK, custom exhaust manifolds that clear the P/S pump and Alternator. I have since mounted a Astra pump in the boot, which I don't hear in the cab. As for the coils they are remote mounted and I run spark leads and tubes.
@@STREETMACHINETV more than enough for me. Did the conversion about 16yrs ago. Got 475whp on pump 98. Have recently built bottom end (Ross pistons, spool rods), kelford turbo cams etc and will be getting tuned in the next few weeks. It's a handfull for an old bloke.
Stock intake easily ftw, imo the elephant trunk is ugly and its probably horrible off boost on the 4L. Curiously was rear mount turbo ever considered for this build and if so what prevented it ?
Have you considered spacing the K frame down a little to lower the engine? Also is that plenum symmetrical ? If so the mustang one could go to the left side away from the booster.
Double comment so my apologies Al and woody tend to use suby boosters in a lot of their builds and mcm used a hilux/hiace booster in their rb 240z too Just a couple potential options, there’s definitely gonna be one out there for you
Run hydraboost , these are small, and have great pedal feel however it does need a power steering pump. There are some larger trucks and maybe some larger SUVs that use . electric over hydraulic. Search for Electric-Hydraulic Brake Booster
Have you considered an electronic brake booster rather than a traditional vacuum style? Electronic are reasonably common now for EV conversions given the lack of a vacuum source
As ao said in the previous video, was not a fan of the gonzo intake manifold, while I agree for show purposes it would look wicked but in practice as a sleeper it would be yeah. As for the other issues, lol, imagine Toyota in 1989 looking at the VN engine bay and saying how can we make our quad cam V8 fit, you can see why the said F it V6 pushrod it is. I'm sure you will get it all working and be doing high 10's in no time.
Just a thought.... Going up is a problem. Just come on a mental frolic for a moment... What if you channel the lower manifold and have the centre of the throttle body dropped by say 100mm. Of course you'd then have to close the top too. I'm thinking about the clearance *under* the lower manifold allowing a fabricated round section say 125mm wide, to which you could attach the throttle body. It will change the air flow to go from low then up into the runners, but air bends well, as seen in LS3 manifolds. Just ideas, I don't have the car in front of me let alone the TIG skill needed.
Hi scotty just statred viewing your video ontoyota v8 swap and from angle on vid it appears you may able to machine what gather is the factory intake and gain around 20 to 30 mil and possibly a littlr off skid factory bottom plenium ???
The Hoffs 1uz supra didn't seem to be limited by the standard plenum. Don't worry about it. Standard lead on plug ignition too iirc
Bigger turbo and bigger boost area by way of turbo piping running from the back. And he runs all the boost. Definitely gains to be had by the replacement intake when not going to the extreme.

Thanks mate, and nice job on reading the comments before adding another "Just use an Astra pump..." to the list :)
Just put the stock manifold back on , it'll fit under the bonnet, and you'll still make the required HP
The bonus is the stock can be modded to fit a larger throttle body
Stock intake looks great and with boost will make minimal power difference.
Scotty..............the guy who never seems to get fazed by problems that arise 😊
Cause he isn't paying 😂😂😂😂

Full of admiration for your determination to practically and economically overcome any problem.

Ign1a coils are more powerful than any coil on plug available actually. So it's not a silly idea.
Something I've done and I've seen done here in the states is face the alternator backwards! It doesn't care what way it spins!
That's interesting
@@STREETMACHINETV I hope it helps you out!

Hey Scotty, What about a remote booster'? The VH44 Booster is a remote type for a single circuit system, surely there is a more up to date type?
When you have got the manifold / plenum, spray them in red crinkle paint.
Then polish up the high points, and the Toyota symbol and stakes on the plenum.
Vn group a bonnet cover should give you a bit more room,scotty
You could use that Holley plenum that you already have flipped around with a modified 90deg bend on it for the throttle body. The brake booster might still be in the way though.
With the bonnet put spacers in where the bonnet bolts down it lifts the back of the bonnet off and still looks standard had to do it with my l67 hilux
hey scotty, maybe you could run a remote booster like a older land rover, hide it under the driverside guard similar to the evap ball thing on the passenger side

Scotty, what about using 2UZ or 3UZ intake instead? The throttle body is mounted to front of the intake.
I've never seen one, but sounds interesting. We have a solution now.
@@STREETMACHINETV 2uz and 3uz petrol Landcruiser
@daleruse3865 I know of the motors but haven't physically seen one, so I don't know the difference other than capacity
This thing is fighting ya hey 🤣 really enjoying it mate 👍
Tell me about it
I used castlemain rod shop kframe spacers to gain space under bonnet on my VS commodore. They vary in size depends what you need to clearance
The sound effects were good
Don’t they say we need another inch 😂😂😂
Looking at how much material is on the manifolds surely you could mill sum of the excess material away to get it to sit lower under the bonnet.
Hey have you considered a astra or Volvo power steering pump and I reckon put the hump of a BA xr8 into the bonnet.
Holden Astra pwr steering electric pump conversion, and i think Subaru boosters are very small (or Corolla, cant remember)
You could also use a Mazda electric power steering pump. The one on the 2006 Mazda 3 is small enough that it sits behind the R/H headlight.
I used to have a HQ, but the booster was from a HT, if memory serves. It was longer and much smaller in diameter.

Those Astra pumps draw alot of amps, we discovered that on the MX5 before we made it manual steering

Also is that plenum symmetrical ? If so the mustang one could go to the left side away from the booster.

@@STREETMACHINETV . I must have missed the explanation as I don’t recall hearing it.
How much material could you machine of each manifold face to grab half an inch or so and still support boost?
There doesn't really appear to be excess material to do anything like that
can you lower the cross member to make it fit better ? i did with a vz commodore with an LSA to keep it under the hood
Can you flip the Holley to the other side. Run throttle on passenger side.
Can you flip the exhaust manifold the other way, blank off the outlet and weld on an outlet facing down between cylinder 1 & 2?

Idea for the bonnet, you could use an xr8 bonnet
You could try making a spacer to raise the Toyota plenum to increase the runner length, and cut the throttle plate off and weld on a bigger one.
You would have to cut more that the throttle plate off. 70mm is plenty
Turn the intake around backwards so the feed is towards the firewall, put an air to water intercooler inside the car
