Roman Posted February 8, 2023 Author Share Posted February 8, 2023 Its probably so that if the car takes a big shunt, which I'm guessing is likely. The it will deform but not explode into a million splinters like it would if 100% carbon. Or maybe in the past they had a big shard of carbon pierce the radiator. haha 3 Quote Link to comment Share on other sites More sharing options...

NickJ Posted February 8, 2023 Share Posted February 8, 2023 Aramid/Kevlar is used for toughness (impact resistance) and only when really needed or the engineer is a dick cos its a pain to work with. 1 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Roman Posted February 12, 2023 Author Popular Post Share Posted February 12, 2023 Thanks everyone who's helped me out with this project, I think it has been the most fun and satisfying project I have ever worked on. However, for a variety of reasons it's come time to sell up. I've tried to come up with a price at which I could pass this on to someone, and keep it going as-is but there are a few problems. Firstly I need my ECU and wideband etc back for the Carina. Selling the car with ECU then buying new ECU doesnt really work, because I'm looking at a ~$3k replacement cost. Then I've painted myself into a corner with the e-throttle setup, as I cant just chuck a cheap ECU at it to sell. Then, the shell that this project has been based on is a bit rough. So seems unfair to sell it with existing wof/reg but then no cert. Also not keen on selling someone my wiring under the dash. Haha. It's reliable but its just messy. If someone wanted an awesome vitz project, would make sense to reshell it into a good condition Vitz RS. However, I'm super looking forward to getting back to the Carina eventually now. I've been in limbo with that car for a long time not knowing what to do, and this car has filled in that gap and been friggen amazing. I wont have any money to do anything meaningful with it for a long time, but I've at least bought an engine block before I've run myself broke with house stuff. So I can do some scheming and 3d printing some prototype intake parts etc while I'm poor. Here's a link to the post parting it out if anyone's interested in some bits. Thanks for tolerating my rambling for 75 pages about Toyota Echo stuff. Jesus. 6 5 16 Quote Link to comment Share on other sites More sharing options...

Popular Post Roman Posted February 12, 2023 Author Popular Post Share Posted February 12, 2023 It's been bloody awesome fun alright. But also it's a bit tapped out now. You cant get any 1NZ cams bigger than 264 deg, and there were only "admin" sorta jobs left to do like sort out an air filter or tidy it up. Things which made the car nicer but fundamentally didnt alter the recipe any further. I'm actually really happy to end a project on a high note. It seems a lot of projects end up being sad to look back on if they ended when a car was crashed, or motor blew up, or sold to have kids or whatever. This has just been grin factor 10 nearly all the way through. Also I've managed to infect some other people with the concept of vitz pesting, and the parts from this car are going to be used in some cool setups. Also worth noting that back when this car was standard I came incredibly close to just giving it away as I no longer used it. What an absolute adventure it's been on, at the tail end of it's life instead. How good! 20 5 Quote Link to comment Share on other sites More sharing options...
Popular Post VitesseEFI Posted February 12, 2023 Popular Post Share Posted February 12, 2023 This makes me sad. The extra performance that has been wrung out of this once ordinary small car, on a budget, by cunning raiding of the (used) Toyota parts bin, and then still more cunning, mixed in with 3D printing, carbon-fibre bothering and a whole heap of graphs and charts..... not to mention plenty of skinned knuckles and general back-breaking effort, is just startling. 9000 rpm......Surprising track performance, astonishing 1/4 mile times....... and yet, only one oil filter assembly put into low-earth orbit...... This is the project that tipped me into joining this forum, no regrets on that score. Even if I'm a bit confused by the local language at times 17 1 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted February 13, 2023 Share Posted February 13, 2023 This has indeed been an awesomely fun project to follow and the best thing is - you're still here, you're still Dave the graph, you've got another motor to play with so we can all look forward to following your upcoming posts on your carina thread with the V6. Then after that's finished it'll be the echo thread with a V6 3 1 Quote Link to comment Share on other sites More sharing options...

It's been so cool to watch as you have progressed with the development and tried things. I agree it's reached it's natural conclusion without a lot more major work. I don't believe you can ever work on 2 project cars at the same time and give them both serious attention, so it's going to be awesome to see you get back into the carina. 3 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted February 13, 2023 Author Share Posted February 13, 2023 Yeah I agree with that. The echo has been so much fun that it's been a 100% distraction. And thats been absolutely awesome, I've loved it. Not only that, a lot of the tricks I've found out (such as adapting bike throttles, finally figuring out how to 3d print manifolds effectively, how to make shitty carbon stuff) Will all come in handy. Going to be cool. 7 Quote Link to comment Share on other sites More sharing options...

shrike Posted February 14, 2023 Share Posted February 14, 2023 Just a note re DBW ITB the 2022 Honda CBR1000RR has 52mm DBW ITBS Not sure if that's Inner Diameter however, I suspect the 48mm BMW S1000RR ones wouldn't be a limitation even with boost however 1 1 Quote Link to comment Share on other sites More sharing options...

You cant get any 1NZ cams bigger than 264 deg, This is probably a moot point, but i wanted to bring it up. We all know why we swing the intake cam for rev range and performance gains, and everyone says exhaust cam timing is barely worth the effort, and you can't go bigger cams because the valves clash...... But...m Consider this, what if you swing the exhaust cam on its own vvt strategy purely to get the valve out if the way to allow even more wild intake cam size and timing? / Probably wouldn't work dumb idea? 1 Quote Link to comment Share on other sites More sharing options...

But...m Consider this, what if you swing the exhaust cam on its own vvt strategy purely to get the valve out if the way to allow even more wild intake cam size and timing? If you have a steep valve angle, as in, the valves are more vertical. Then you need absolutely insane amount of lift and overlap in order for both of the valves to hit. At full intake cam advance, my intake valves are chasing the piston down the bore as close as they can. So hitting exhaust cam isnt the limiting factor. 4 Quote Link to comment Share on other sites More sharing options...
kpr Posted February 24, 2023 Share Posted February 24, 2023 Valve to valve isn't an issue in my case either with wide angle head. piston to valve = yes. The exhaust cam timing is not so much that it can be off and work. it needs to be right and when its right, its pretty happy to work across the whole rev range. when its off it kinda sucks almost everywhere 2 Quote Link to comment Share on other sites More sharing options...
