I added a bit as to how I see that dyno graph working-

Ok, that is all changed now, and I thought I'd make a separate topic of it. It has eight alloy inserts in the TVIS plate, and the smaller diameter ports have made all the difference. This is why people say Toyota made the bigports too big! https://www.rollaclub.com/board/topic/85687-bigport-tvis-mod-to-all-8-ports/ I'll stick with that while I get the extractors moved, get some stone-chip spray on the sills and do some tidying up. Overall, its a big improvement around town and on the 40km cruise to Redhead Motorsport and back each day.

Well, the Girls KE70 has had the 4AGE for 5 or 6 years now, and more recently a Haltech running it. Behind that is the lightest flywheel I've ever seen, and a pair of Wade 267deg cams, extractors and a 2" exhaust, all on the stock inlet system... It has always been a dog low down, even with a stock ECU it couldn't hold an idle, and the last mods were Banjo making me a Hall Effect sensor setup for the distributor and a set of COPs. Then it died earlier this year and I found enough carbon under the valves to drop the compression at cranking speed, and the TVIS plates heavily carboned up. Having made some movies under the inlet system with an iphone I realised the Haltech told the TVIS to open up or close but in the wrong language! They had been open all the time! I found an output in the Haltech that worked like I wanted, but opening them was nothing great.. I could move the opening of the TVIS throttles anywhere in the rev range and nothing made a big difference. The 4 ports usually open can do what the motor needs. So I figured I'd get rid of them and run 8 throttle plates against the head and no throttle body, using the stock 8-runner inlet. First up was a look at Garage4AGE and his dyno runs. All the power increase is before 60% throttle, then you get diminishing returns. Then an excellent tuning page I came across, giving the max power per throttle body size. https://engineeredbydesign.co.uk/Pages/Calculators/ThrottleBody.php Stock is four 30mm runners in the TVIS system, with 4 closed. That is good for 220KW at 7500rpm Open the other 4 TVIS 30mm runners and its good for 440KW!! The stock 55mm throttle body can power the 220KW that takes 4 TVIS runners, although 60mm would be better. Which brings up a interesting question, does one throttle body of a certain area flow as much as 4 ITBs adding up to the same area?? Each ITB flows once in 4 strokes, then it flows nothing for the rest of the time. A single throttle body flows its max all the time, just dividing that air flow from one cylinder to the next. So in theory I think the 4 ITBs should be smaller than a big single.. Anyone know about this? OK, meanwhile, everything is waay too big for what I want. I put in a 1600cc V8 to get figures for 8 runners working, one for each valve. To get 125KW at 7500rpm needs eight 14.5mm runners!! Far too small to even engineer, so I worked on 20mm. In theory that is good for 200KW, matching the stock throttle body, and not many slightly modified 4AGEs are going to worry about more than that. These are 20mm coins in the 30mm holes of the TVIS gasket. So while Josh was away for the ARC round in Tassie I bought a 33mm round bar of alloy and got on the lathe. I made them 30mm long so they stick into the head close to the injector, stepping them from 30mm OD down to 25mm OD as the port reduces in the head. Then I put the inlet system back on. Did you know you can remove the stock inlet system and leave everything else like the injector rail on? Toyota were very neat with this design. Instantly the motor idles now, from cold even! Pulls up the driveway without lots of on-off-on throttle trying to work the revs up, and cruises easily around town at 50kph. I have nice long hill just of of town that I time 60-100kph in 3rd from a particular roadside sign, and its gone from 12.23sec to 11.8sec. That's 3000-5000rpm, the most useful range for daily driving. I haven't found any loss up to 6000rpm, I don't need more than that, and everything below is better. I've been changing the Haltech fuel cells all week as it suddenly ran lean, more air getting into each cylinder. I'm dying to see the fuel usage after a tank full. I can put the original TVIS throttles back in, or I can drill right through the lot, mount tiny 20mm throttle plates, put a cable in the middle where the TVIS actuator is and a TPS on the back by the firewall. Then it needs a vac system for the brake booster or unboosted brakes. Then you get instant throttle response. I'll see how enthusiastic I am in 6months!

With the motor media almost completely overwhelmed, by talk & discussion about EVs; it is always a treat to read the news;; & read a story today, about an "olde skool" Corolla. Olde Corolla, Does the Gibb River Road in Style Full Marks Jonny Charles ! On top of that, He serves coffee to other travellers & calls his on wheels coffee outlet; "Cafe Corolla" https://www.facebook.com/10newsplus/videos/meet-the-man-driving-a-café-in-a-corolla-around-australia-10-news/1047960244629879/ Cafe Corolla gets to Mt Hart 💪🇦🇺 | Jonny Charles | Facebook https://www.facebook.com/josh.ball.56679/videos/jonny-flying-through-the-gibb-river-road-in-a-toyota-carolla-so-stoked-to-have-r/1424096706406376/ We salute You, Jonny Charles ! Enjoy ! Cheers Banjo

I also loved Korean comics, and webtoons too!! my fav one is lookism.

Hi Gavin, Nice to see your name pop up again. Cheers Banjo

It's been a long time... but i remembered my password.

How do you reckon that throttle disc transfers rotary motion into vertical motion? I haven't seen that before. An arm stuck out horizontally underneath, pulling on the usual ITB shaft arm and rotating it?

Yeah ! Very much for "show only", & quite a few things needed before it heads off to it's destination, as Taz mentioned. Hmmm ! Interesting mounting of the four (4) C.O.P.s. They look like Denso style COPs.. I can assure you they do not sit that low in the spark plug tubes; unless they have been cut down in length. If they are, Denso COPs, then it is for show, as the primary & secondary coils are wound on top of each other, down the long tubular section of the COP, which pokes down the spark plug well in the head. The only COP type that you could use is a type that has the coils in the head of the dumb COP; & nothing but a long spring in the tubular section. I've just recently given away the "intelligent" COPs, as they combine the chassis ground connection for both the +V trigger signal return; & the coil charging +12V chassis ground return. I've just done some tests on a Ford Falcon BA series "dumb" COP, which has no ignition or smarts in it at all. It has just a primary & secondary coils in the "head section", which is taller than your average COP; as depicted in the photo below. The stork on the BA series Ford COPs, contains just a long spring to transfer the HT voltage to the spark plug. Actually, the Ford BA series COP could be shortened so it just stuck out of the spark plug well, like those in the "engine bay" photo above. Might have to give that a try. The mounting rod looks really simple, with four "pads" welded on to secure the COP hold down bolt. P.S. These BA Series Ford dumb COPs, really pack a punch. I've recently done some tests on one, & is packs a real punch, & charges up to 12 amperes, in just 4-5 m/sec. Cheers Banjo

Engine bay pic is 'Instagram finished'. 1 there's no wiring to the coils or CAS, and 2 there's a water line from the water pump that goes into the timing chain cover. Water cooled timing system? 🤣 Other than that it does look cool.

It does look like they are getting every horsepower out of the 3K that they can!

Hey Guys I do not own this car, I just came across it on facebook, not sure if its been posted before but look at this. Looks like alot of work has gone into this car. I came across his instagram to: https://www.instagram.com/siamrat_ss What a wonderful build.

I have to admit that was my first thought, but there are no death notices! I checked....

Expired hosting subscription maybe. Is Bill himself still around?

Well that's a bummer. been a long while since ive heard billzilla but it was certainly a wealth of knoweldge and I crawled through it many times over the years. The wayback machine does seem to capture a fair bit of it though, https://web.archive.org/web/20250423211059/www.billzilla.org/

I do it for the same reason. Quite often, when I ask Google A.I. to research something, about olde Corollas; it will find the answer I need, & list on the RHS; all the websites it has visited & searched, to obtain the answer. www.rollaclub.com, is often amongst the listed sites. In fact, I just asked Google A.I. which are the best websites, & rollaclub.com, was listed first, & right at the top. Cheers Banjo

Knibusus's words reminded me- "I like to document things so that if anyone in the near future wants to do the same modification, there is documented information for them to refer to and may make it a bit more easier for them. " ..and I used to read Billzilla's pages a lot for 4AGE info. Now it shows- "Account Suspended. This Account has been suspended." www.billzilla.org/

Cheers @Banjo I like to document things so that if anyone in the near future wants to do the same modification, there is documented information for them to refer to and may make it a bit more easier for them.

Thanks for the photos. Very nice neat & well constructed exercise,. Cheers Banjo

Today finally got everything back together. Ported the intake manifold at work. Installed the headers and put everything back together Can not wait to get the exhaust system done and finally drive the car. Has been sitting in the garage for 8 months. When its all done gonna take it to a Car and Coffee and enjoy the cruise.

Well done! That will solve all the problems.

The stars are aligning, I forgot I had a spare intake manifold from a 4k engine that I had laying around Took it to work and put it in the robowash, and put big bertha on it to remove the EGR nut. Robowash and Wire Wizz came out not to bad no sure if i should vapour blast them and hit it with some hight temp chrome paint. Test fitted them to the engine and man both the stock intake manifold and extractors are the same flang thickness and it clamps tight and flush to the block, M10 washers are abit to small to cover both the intake and headers, so I will pick up some M12 and see if that helps, but even with just the nut they still clamp nice and tight. Just need to hit the intake manifold with the carbide to port out the intake manifold for more airflow, not sure if it really makes a difference but more air for a 2 inch exhaust system let the 4k breathe babyyyy. Finally get it all back together ready to tow to my exhaust guy to put a 2 inch exhaust system on the KE70 Wagon.

Yep I think that is the go, even these washers in the picture normal m10 washer if i grind the side down keeping the middle circle it will still fit on the stud and fill the gap so i think I'm gonna grind down some washers and do the superglue method, thankyou for everyones input and help.
