The majesty is there with solidworks, but the raw emotion has been lost. It's not a graph, but, its MSpaint used for something MSpaint shouldnt be used for. Which is in keeping with the spirit of things. 5 Link to comment Share on other sites More sharing options...
Ashkellybarr Posted February 16, 2020 Share Posted February 16, 2020 The APS that came with me K24 is a box that sits in the engine bay being feed from a normal cable pedal. Means you can put the box anywhere and just get a cable to suit Link to comment Share on other sites More sharing options...
Roman Posted February 16, 2020 Share Posted February 16, 2020 Yeah the Altezza throttle is like that, it has the APS on the throttle via cable pull. But looks a bit tidier to not have the throttle cable and extra wiring in the engine bay. Link to comment Share on other sites More sharing options...

projectb10 Posted February 17, 2020 Share Posted February 17, 2020 Thanks for setting out the FP versus injector duty cycle considerations. That was an interesting read. The external AFR option, usually mounted remotely to the fuel rail is also a space hog. Prefer something neat and OEM like the Bosch 4 Bar FPR. Might work for you if your current direction of travel with more injector duty time etc etc doesn't play out https://www.bosch-motorsport-shop.com.au/fuel-pressure-regulator-4bar Probably wont work in your application but this site offers a Bosch Regulator housing adapter that is designed for the Bosch FPR. There are probably similar offerings out there. https://www.kainjection.com/product-page/bosch-regulator-housing-adapter 1 Link to comment Share on other sites More sharing options...
Roman Posted February 17, 2020 Share Posted February 17, 2020 Hey that's cool! Thanks for that. Someone also pointed out to me that the LS1 FPR, although it sits externally, is a factory 60PSI one. In factory form it sits close to the gas tank and feeds a dead head fuel rail, so it's kinda like what Toyotas etc do internally inside the tank. I'm confident that it'll be fine with the lower pressure though, as the factory Redtop 3S injectors are a slightly lower CC rating and from factory runs at 43psi.

projectb10 Posted February 17, 2020 Share Posted February 17, 2020 Hesitate to suggest it.... but could probably also make this work fuel rail wise, https://www.bosch-motorsport-shop.com.au/fuel-pressure-regulator-housing But the price is eye wateringly unafordable for what it is!!!! Radium offer a nice adapter which has a port for the FP sensor. 1 Link to comment Share on other sites More sharing options...
Roman Posted February 17, 2020 Share Posted February 17, 2020 This looks like neatest solution for fitting the fuel pressure sensor without an external FPR. https://www.trademe.co.nz/motors/car-parts-accessories/performance/gauges/listing-2529565372.htm Could have it just off the outlet of the fuel filter. 1 Link to comment Share on other sites More sharing options...
Hyperblade Posted June 6, 2020 Share Posted June 6, 2020 Quote Must be able to remove rear coilpack with the factory bulkhead drip tray thing in place. Cutting this, is a bridge too far in terms of losing street car feel. Remote coil packs are a thing! 1 Link to comment Share on other sites More sharing options...
Roman Posted June 6, 2020 Share Posted June 6, 2020 True, but I would prefer to keep the simplicity of packaging and troubleshooting that you get with coil on plug. This will be very close to the point of sump hitting crossmember anyway. 1 Link to comment Share on other sites More sharing options...
fuel Posted February 9, 2023 Share Posted February 9, 2023 I'm mcloving the direction this is going! Please be successful with a V6 transplant cause I sure as hell wasn't haha. Regarding the 2GR and 4GR block height, you'll probably find they are the same height and the piston wrist pin height will be different between the two to accommodate difference in stroke while using the same rods. It would be easier (read: cheaper) for Toyota to change this piston wrist pin height between the 2GR and 4GR than it would to make two different block castings, lower inlet manifold and coolant crossover pipe etc. 2 Link to comment Share on other sites More sharing options...
AllTorque Posted February 9, 2023 Share Posted February 9, 2023 Are you aware some 2GRs have direct and port injection? Perhaps this could be adapted to your 4GR. Supercharger kits are also popular on the 2GR 1 Link to comment Share on other sites More sharing options...
Leone Posted February 9, 2023 Share Posted February 9, 2023 Just went back to look at the build thread... started in 2007! Guess the progression just keeps on keeping on, Adds to the follow list. 1 Link to comment Share on other sites More sharing options...
shrike Posted February 9, 2023 Share Posted February 9, 2023 Nice, know some ex Toyota Australia people that think the 2GR is one of the best motors Toyota has made and the 4GR is just less capacity. Apparently they make ok power with a intake and exhaust change as the factory stuff is restricted and they run factory rich I know you'll do your magic though, hoping for DBW ITBs again Some Hiluxs had the v6 as well so may be able to use a RWD box from that family. 2 Link to comment Share on other sites More sharing options...

Supercharger kits are also popular on the 2GR Yeah, but it looks like since they have a top mounted injector they have more of a bend in the port. So I'll mount injectors high up anyway, as need to remake intake either way. The main problem with DI only is going to be finding non sludgey intakes, will be interesting to see what this motor is like. Has 110,000km. 1 Link to comment Share on other sites More sharing options...

Bad news because it would mean a heavier piston, but good news that if I do make some pistons and rods, could use an even longer rod. I cant use dual E-throttle unless I use some sort of canbus arrangement, but two of something like this would be sweet. This bike makes 150hp with 3cyl, so its at least capable of 300 with a 6. 1 Link to comment Share on other sites More sharing options...

Roman Posted February 9, 2023 Share Posted February 9, 2023 That's an absolutely excellent option, however a 4GR was $650, what's a 20B these days? 3 Link to comment Share on other sites More sharing options...
