mjrstar Posted August 1 Share Posted August 1 In my experience a lightweight well handling na 4 cylinder the handling and braking plus how well the gearbox will shift & decent driver will trump whatever peak power people talk about on the internet. I do however suspect it will go hard for what it is, plus will make doort noises, and it's clear to see you have considered a 2zz. So ticks all those boxes. My honda wouldn't even go under a 14 flat 1/4 mile but is capable of competing closely with some pretty modified turbo awd race cars. / skid pics aren't loading? 6 1 Quote Link to comment Share on other sites More sharing options...

I’m most interested in the result because most people on the internet with 2zz’s are celica/mr2 or lotus weirdos who pay the money rather than engineering things properly themselves. I haven’t seen any properly impressive NA builds or power for that matter. Skids are a while away still.. but I do have an excess of shitty 17” goodrides in my tyre stash 3 Quote Link to comment Share on other sites More sharing options...
Roman Posted August 1 Share Posted August 1 I forgot about this, but ages ago I helped a mate wire a link into a 2ZZ runx rally car. So from memory this was completely standard mechanically, apart from ECU install. So still that super grotty exhaust manifold and so on. So made pretty sweet power considering. Based on this powerband looks like it should keep going for another 1000rpm, guess they were playing it safe. But was easy to tune out the dip from the factory lift being set at a stupid RPM to feel more VTEC-ey. 3 1 Quote Link to comment Share on other sites More sharing options...
Rhyscar Posted August 1 Author Share Posted August 1 Yeah wow that’s a super flat power delivery when you get vvt working. And the high rpm dip is most definitely the yuck exhaust manifold situation. Will be interesting to see how it goes above 8000! 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Rhyscar Posted August 7 Author Popular Post Share Posted August 7 Unexciting update but lots of little jobs being ticked off the list. Might get to drive it down the street this weekend fingers crossed. Luckily, oil cooler was under warranty <1yr old so Aeroflow replaced it. Pretty grateful for the service. Oil adapter block was leaking cause I forgot to put an O-ring in it. Pretty silly mistake but all sorted now. Here's a quick rev and sound check. I'm amazing at how snappy and good it sounds. 3" with 1x adrenalin R rear muffler and it isn't painful on the ears. Much excitement for whats to come. 12 Quote Link to comment Share on other sites More sharing options...
Popular Post Rhyscar Posted August 14 Author Popular Post Share Posted August 14 Oh man what a ride this has been. After running it for above vid and a few other times that day to tidy up fueling at idle, I got out to see it had dumped all it's oil on the driveway. Turns out it blew the remote oil filter adapter right off... Luckily, I think I caught this in time to not run the engine dry (fingers crossed!). So as always, there's a bit of a back story where some time ago, I couldn't figure out fittings for the 2zz filter thread to adapt to the aftermarket (whole knows what brand/origin) oil filter adapter. And then in a seemingly genius 'EUREKA' moment late one night I thought I got it sorted and slapped everything together. Fast forward to current day and yeah well, it wasn't sorted, and it was completely the wrong thread. Didn't even damage the thread when it blew off that's how loose it was! Almost brought me to tears after the amount of effort and energy I've put into this car. Had to take a few days off to try forget about it and start to think about it a little more rationally. So after not being able to find the right adapter, with the help of @Geophy, we bastardised a m20x1.25 truck brake fitting and welded it to the 2zzge bit like so. Was going to do with the grinder, but better judgement got the better of me and decided it would be best if we did it on the lathe so I can be 100% confident it's square and won't cause any issues. So it works now, has good thread engagement and doesn't leak. Win! only issue was it tightened up in the wrong spot meaning my short hose to oil filter wouldn't reach. Had to change fittings and re-make the line so it loops around. This is a much nicer solution so happy with it, just more effort required. So managed to run car again during my lunchbreak after a few more liters of oil... Doesn't sound like its done any bearing damage, has good oil pressure too. I'll probably drop the oil now and cut open to filter to double check nothing went amiss. Also here's a quick 3-4000rpm sound check for rasp the rasp-meter. Isn't as bad as I initially expected to be fair, but yeah its def got some rasp. Headers are starting to get a little colouring on them The other day I also completed the mind-numbing task of swapping the clutch and rear brake master cylinders over. Turns out I'd installed these the wrong way around years ago, then kept them like that.. Massive PITA due to a spacer between masters and pedal box but got there in the end. Many, many curse words were issued while lying upside down in the footwell, doing tiny spanner movements many many times over (25mm of thread), with a brake pedal in my grill. Not fun. Does anyone have any good guidelines for engine run-in? Engine has been sitting for 11-12yrs. Has fresh bearings (didn't touch crank), valves (oversized) and Headgasket but from memory we didn't touch the rings and we left the factory liner alone. 7 3 Quote Link to comment Share on other sites More sharing options...

You've dropped the oil already, so fresh filter and oil, then just drive it (maybe take it easy the first few 100km) Id probably run some higher zinc oil as that will help with lubrication, wont hurt anything and should help with reducing wear/friction How clean is the motor? if the motor has some buildup you could run some higher detergent oil to help clean it out Main reason for breaking in an engine are for rings to seal and not bearings Probably do an earlier oil change just to make sure everything looks ok 2 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted August 14 Share Posted August 14 I'd say if you haven't done rings then it's ready for full send I reckon. On a side note a mate of mine has a b16a racecar he wanted higher compression so put some second hand pistons in it, inspected the rings and bores and decided the 250,000 km original rings were still good to go. So no need to bed rings, and can get straight into swinging the engine to 9200 rpm again. 3 Quote Link to comment Share on other sites More sharing options...
Rhyscar Posted August 14 Author Share Posted August 14 Cool thanks @shrike and @mjrstar , consensus is it's good to go. I found a 5w-30 Penrite mineral oil that I'm running it on currently. A little unsure what spec to go with next, may just default to Motul 300v because it literally works with everything racecar related. Although I'd be interested in what oil the TRS cars ran in these engines? Surely a Castrol being toyota? 1 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted August 14 Share Posted August 14 It sounds great man! I can't wait to hear it at full song. Here's some info about engine break-in. There's also a break-in module in the engine building courses on HPA that I know you have access to . 3 Quote Link to comment Share on other sites More sharing options...
