RUNAMUCK Posted July 2, 2022 Share Posted July 2, 2022 I was taught they're actually elliptical, and they're finish ground using a cam grinder style set up? Log the number of 9k pulls before it goes bang. (Then show your findings on a graph) The after you replace the next engine, start fund raising for forgies and rods when you hit half the number of pulls. In my experience, by the time you fit your third engine, the enthusiasm begins to fade. 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted July 2, 2022 Author Share Posted July 2, 2022 Once I've moved house and sold the old one I'll not be in such dire financial situation. Will just be a while. So if it needs pistons I'll buy them eventually. Goals for the meantime is make it to OS drags, and the Toyota Festival trackday at Hampton. Then whatever else comes up. Then also see how the 1300 setup goes. 3 Quote Link to comment Share on other sites More sharing options...
Spencer Posted July 2, 2022 Share Posted July 2, 2022 Pretty sure some aftermarket pistons and rods are in your future. It will still be a pretty cheap fast car with those bits done. Missed chucking some corn in the engine fund, once the engine is in start one for KPR/Sheepers headers/ exhaust combo. 3 Quote Link to comment Share on other sites More sharing options...
Spencer Posted July 2, 2022 Share Posted July 2, 2022 Actually how do we get this on garage 4AGE? Are non 4AG allowed? 4 Quote Link to comment Share on other sites More sharing options...
Roman Posted July 3, 2022 Author Share Posted July 3, 2022 Not sure about that, I think that would be even more blasphemous than his 20v content 2 Quote Link to comment Share on other sites More sharing options...
Popular Post kpr Posted July 3, 2022 Popular Post Share Posted July 3, 2022 ^ plus logistics So yesterday.. Cool someone some sent me a parcel. hmm yeh nar, one step above receiving 20v parts So to keep everyone in the science loop, i'll fill in the header construction part Stock are 32mm od diameter The aftermarket ones are 35mm od Seems to me the 35mm od would be a good size for the power chasing. Idea was to extend one set or the other rather than starting from scratch. because budget But dilemma was available tube size. can get 32mm od, same as stock. next size up is 38mm od. no 35mm. probably something in between if went to mild steel., but oddly enough can get stainless cheaper In meantime i made this amazing jig that closely replicates a echo floor pan and exhaust system. from potatoe 2 pictures @Roman sent me Back to sizing issue. after changing my mind 12 times. decided to chop up the aftermarket ones and go for a stepped setup. Chopping the collector off and running 38mm tubes from there onwards. 35/38. Because we all want to see that 10,000rpm 2nz anyway for reference 38mm od is what i use on my 4age headers. Need to order some stuff, but had a few leftovers hanging about for a bit of a mock up. looks like should work out all good. 25 6 Quote Link to comment Share on other sites More sharing options...

Speaking of 20v, has anyone seen the 4age 20v turbo GR yaris rally car that Hayden Mckenzie has hidden away? I have nothing to add other than have you considered a 2zz or 20v turbo?

Roman Posted July 3, 2022 Author Share Posted July 3, 2022 Why would anyone put a 20v into a GR Yaris?! Weird. haha I have indeed considered a 2ZZ. But it's a bit beyond my skillset as it requires a whole lot of chopping the front of the car up to make it fit. And motors are comparatively expensive. Pretty sweet results though. 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted July 3, 2022 Share Posted July 3, 2022 Why 20v? The only reason I can think of is that at the time no-one had invented a clutch and bellhousing to run the sequential gearbox.. 2 Quote Link to comment Share on other sites More sharing options...

mjrstar Posted July 4, 2022 Share Posted July 4, 2022 Maybe he needs to send it to garage 4age and get some turbo delete and a 16v head with patented peach can or noodle induction system? Sure it's a 20v but I would hoon though.. 4 1 Quote Link to comment Share on other sites More sharing options...
Vintage Grumble Posted July 4, 2022 Share Posted July 4, 2022 Well it makes more sense that it was a std yaris, not a GR to begin with. I was very confused there for a second. 5 2 Quote Link to comment Share on other sites More sharing options...

I only caught the back half of the conversation at a recce for a rally stage a couple of months ago (he was running his evo at that event) , but I think it is destined for 3 cylinder treatment down the track? 2 Quote Link to comment Share on other sites More sharing options...

87creepin Posted July 4, 2022 Share Posted July 4, 2022 No 4afe+t love? Driving4answers is doing that on his YouTube channel, aiming for 300hp atw I think? Cheap and no one will cry if they're destroyed as opposed to a 4age Quote Link to comment Share on other sites More sharing options...
Popular Post kpr Posted July 4, 2022 Popular Post Share Posted July 4, 2022 With turbo tech these days, Its pretty easy to use any engine you feel like. The limitation is just engine strength. from there onwards just a money pit of how strong can build the engine. Old mate you speak of has some good videos of explaining stuff. but end of the day its just stuff hes read or watched and put in an easier to digest format for the masses. he has managed to make a 4age make less power than stock though. If applied some of the stuff roman has done na, to a turbo setup would make stacks of power. some of it can't be transfered over, but a lot can. but yeh would just end in nuking engines till point of $$$$ billet blocks etc have been asked to do na stuff on 7a/4afe heads quite a lot. but is kinda pointless without any aftermarket support for cams. can only go so far with little stock cams dont get me wrong im obviously all for making crappy or different engines make power. but downgrading the engine you already have to try make power doesn't make a lot of sense /spam Pipes have been ordered for header construction 13 2 Quote Link to comment Share on other sites More sharing options...
