[quote=meerkat8701;11519563]hello my neighbour from norge! cool build nice that your getting it all back to one colour again! you seem very quick at whipping engines in and out as well =) i noticed that you had block off plates on both of your engines. was that your acv? im really having trouble working it out from everything on the net cos i have a swedish-sold s4 n/a seems to have minor differences compared to the american versions. i put up a pic on my thread.

https://www.rx7club.com/build-thread...1030202/page5/

any help is appreciated so that i can maybe get my *** over to norway and get left behind by you on the track hehe =P[/quote

Hi, yes it would be good if more rotarys came to "sommertreff" at Arctic circle raceway, but i don't think i will be leaving many people behind just yet, my car dies every time water temp hits 50C, so i need to figure that out before i can do anything.

I'm not shure but i think the acv block of plates might be different on the euro lim and us lim, but i made mine myself out of 2mm alu plates, 15min job if you got a drill and an hack saw.
Just take it off and make a template from cardboard and get some alu

The euro lim uses vacuum actuators to open the 5/6 port butterflys, if i where you i would get them to work properly, or leave them alone if they already do. Just wiring them open is not very good option for a wide powerband.

 

thanks for the tips pettersen! yeah man i really want to get on the track i have never had the chance to do it before cos none of my cars ever work haha.( im crying really) i checked out how long it would take me to get to the raceway its about a 12 hour drive. geuss i would need to bring a tent as well! its starting to look like ill just have to ask the guy whos rebuilding my motor what to do when i go to pick it up next week. if he doesnt know i would probably faint from shock =)
hope the cooling problem gets solved so you can get some time behind the wheel this summer before that lovely six month long night comes-a-knocking! ill be keeping an eye on your thread to see how your getting on.

 

I live in an emissions state and every two years must pass a visual and rolling road sniffer test, that's why my rat's nest is intact.

I've never spent the time/energy to determine precisely what is "emission" and what is "engine control" and everything works, so I left it alone.

Unlike Mazda, who had the grace to hide most of the emission stuff under manifolds, Nissan slathered their crude early emission crap all over the top of the intake manifold, so the Z is going to enjoy some extra attention and possible deletion in this area.

 

sounds quite harsh. there are loads of people on this forum that seem to be at the mercy of very stringent emissions tests. rolling road? jesus now i get it. from my experience here, they have never popped my hood so no visual test.
a friend of mine had a suspicious tester once open his hood and try to say that he had modified it. (which he had a little)
basicly my mate in a roundabout way challenged his knowledge of cars and then shot him down in a ball of flames haha. that was the end of that conversation!

they just drive it round the the testing centre to get it to what i assume is display the correct co2 values then they stop it outside and shove a pipe on to the exhaust and leave it idling for a minuite or two then they take that reading and thats what they go on. i havent failed one yet but i havent tried to "besikta" a rx7 yet either hehe. the proof will be in the pudding and there will be some ethanol in my tank too

i hope you will be doing a build thread for the fairlady? i do enjoy reading your witty descriptions of what you do so if you are gna do so send me a link =)

tmrw i get a confirmation of when my motor is ready. got proper butterflies in my tummy

 

I have yet to find a Z forum to call home, so for the nonce I'll just continue on in the She Followed Me Home thread and see if anyone notices it's a Datsun, not a Mazda.

It's hard to appreciate just how good this forum is until you search for it's equivalent, the Z-car forums I've seen just don't compare.

So, once you get the motor back are you ready to drop it in?
Bet that's exciting.

 

This is true. The other forums i have checked out seem to have such low activity and the thing i love moat is that People are helpful, humble and have Good senses of humour. It is a proper pain in the *** having to read through some stupid argument to not even get the info you were searching for in the first Place. Tbh, i have the manual for my Mazda, both the Book and i downloaded some others, but i have hardly touched them because with a bit of searching, i find the threads here mkch more comprehensive. (i still need stuff explained to Me in laymans terms). I should certainly Hope People can Tell the difference between the two! Cool i look forward in anticipation to see you getting it looking respectable!

I sent a text to check his progress and he Said i can ring him after 20:00 tonite then ill get a confirmation. Feels like im gna get it this Week. Im pretty much ready to put the Engine in i cant really Think of anything Else i need to Do apart from sort out filters, New sparkplugs, oil (tranny and motor) and some New brakepads for the front. Super exciting!!

 

by the way on the subject of other cars, i wasnt idle yesterday, i remembered that i had a subwoofer in the cellar and the sound in my nissan micra is pitiful so me and my mate popped it in the boot. now i can terrorise the neighbours with some dub reggae basslines hehe



five hours and 38 minuits till i get confirmation on my motor....not that im counting or anything..

 

I hope the motor happens for you.

The weirdest thing I've found (so far!) about the Z forums is how indecisive they are.
It was a remarkably long-lived platform (1970-1978, basically unchanged) and they've had 40 years to play with it but there is still no consensus on good mod paths.

For instance:
-Many complain about the puny wiper motor (I don't recall this being an issue for me, but whatever...) and there is a stickied "upgrade" thread that uses a Honda replacement.
However...the motor does NOT bolt in (mounting plate must be redrilled and slightly ground for clearance), it's shaft does NOT mate with the Z relay arms and when finished, intermittent didn't work. Seems like a downgrade to me.

-Everyone seems to know about the Toyota truck front caliper upgrade (It bolts on and gives you 4-pistons, much like swapping up to Turbo brakes) but no one says much, if anything, about booster/MC changes and what effect this change makes to the braking balance...remember, these cars have rear drums and the stock MC has residual pressure valves (which I don't really understand, just know they are there for some reason).
I'd have thought all this would be canonized by now but it's not.

Oh well, enough of my bitching, back to the saga of Frosty the Frozen Rotary.

 

Clubroadster and s2ki have always been awesome for me. I'm on rx7club and s2ki every day. I used to be in the market for an s2000 and never left the forum because I loved the community. Clubroadster was when I was thinking about a first Gen Miata.

What do you have left before the engine gets installed? Will the car be running/driving once you get it back?

 

thanks man me too!

i spoke with him yesterday evening and we have confirmed that next thursday he will be definately ready and i can go and pick it up then. yay!

thats what i love with rx7 club. things are very well documented and explained on here and its helped me a shitload since i got my fc. i even see it as a fun part of owning an rx7 its nice to be able to join a community of car enthusiasts because if it wasnt for them we would be driving lentil~driven fart-rafts by now.
gotta love petrol heads=)

i also mentioned to him my concerns with solving the acv. he said it was fine to take it away but i will need to do something to actuate the auxilary ports. i have seen a solution here involving an electric pump it seems like i might be able to pull it off.

plans are to get the engine running nicely. then im gonna have to have to get her through a safety inspection which it wont pass. this is because i have a crack that looks like a 5 yr olds drawing of a snowflake right smack dab in front of the drivers side so ill have to replace that. it wont pass but ill be able to drive it for a month and then replace it via my insurance company. after that im going to sort out some coilovers and widen the steel wheels i showed in post #52. then it'll have a bit of stretch/poke/ stance and ill leave it at that for this year. next year im considering going for a standalone and mapping. i have seen these megasquirt piggybac systems but it feels like i wouldnt have the first hope of adjusting them properly. the price is tantalising though in comparison with a standalone..

 

Wow!! I must say I just had the most enjoyable hour reading your build thread. I just started my own endeavor and hope I can be even just half as meticulous as you. I wish you the best of luck and can't wait to see how things turn out for you.

 

I forgot one thing, I remember reading you got the s5 tailights but they didnt fit. I remember reading elsewhere that they require a little bit of a modification to get them to fit right. Anyway I hope it helps!

 

thanks man! im not the quickest person in the world at getting things done but im trying to do this to the best of my ability. geuss i just want it to be reliable as i can get it. fed up of cars that never seem to work hehe =)

problem with the taillights i got were that they are a tad shorter than the american s5 tails (which in my opinion look best) the ones i have are like s5 vert tails. i dont now if they are from a vert or if they put these on the euro 7's to accommodate the longer licence plates we have.

luckily some heroic soul here in sweden has gone through the whole nauseating process of getting smaller licence plates allowed on rx7 (and rx8's) otherwise i wouldnt have been able to have them. i havent looked for any yet i have to order some soon =)

 

Juat a Quick update. Last few Days have been spent at work. I received an email now saying that my motor can be delayed even more! I am becoming almost buddah-like in my patience when it comes to waiting for parts. I have spent quite a while looking at piggyback systems. to be specific the apexi afm neo. It would seem that combined with the upgrades i have done, (Rb header, intake and exhaust porting) i should be able to squeeze a little bit more power out of my n/a without spending a small fortune. Any thoughts on this?

 

Zen-like patience is a real virtue when rebuilding a car.
Especially when you're dependent on other people to make progress.

It'll happen, never fear.

 

Cheers clokker i geuss ill just have to bide my time.. Now the Engine has to wait until the weekend, maybe even next Week. I have a Good friend of mine visiting from England right now so im just Kinda enjoying catching up with him at the moment. I geuss i can start putting together all the bits i need for the installation so that i can feel some kind of flow towards the final goal. I geuss at this rate, ill be happy if i can get it sitting pretty before the snow falls =)

 

I agree with you. It's the only way you'll bring out the full potential of all that you've done to the car so far. I can't say too much about the apexi but my opinion is that it would be worth the effort and most likely easier at this stage than later.

 

yeah because as i understand the factory mapping is quite broad so theres definately a few hp to be found down that road. im pretty sure i would leave it in to a professional tuner to do it though. i cant see myslef ever being able to figure that **** out. seems crazy technical.

on the subject of hp loss/gain, i was just perusing through hyperteks "pics of your engine bay" thread and i couldnt help but notice how many people seem to have open air filters with no sign of a cold-air intake in sight. i wonder why this is because rotarys definately give off more heat than conventional engines and it seems like theres hp being lost there. am i missing something?

i geuss ill just put some heat coating on my headers to reduce heat in the engine bay and then have the original air filter. the heat wrap thing is very heavily debated and seems to be more of a turbo application anyway.. hmmm...

 

During my time with the RX I've tried multiple "cold air" intakes (all of my own devising) but last winter as I played around with some concepts for an even more radical intake, I "temporarily" fit a cone filter with no shrouding on a shortened intake tube. The AFM now sits almost directly above the exhaust manifold and the filter only draws from the bay.

Didn't seem to hurt me at all, in fact, Sigfrid claims the car has never run stronger.

Now, I'm not going to argue against science and it's certainly possible a dyno would show a loss but the butt dyno says I'm good, even in this unusually hot weather.

To further roil the waters, I've never found the plastic undertray to make a tinker's damn worth of difference in engine cooling.
Again, I understand why it should but in practice, I see no difference with it on or off.
Take this however you will, I have no explanation but stand by my experience.

 

Clokker,

That's interesting, so the way that you said didn't that make the air hotter going in the intake? Maybe I'm picturing it wrong. But does intake temperature really affect motor performance that much. It seems to me that the main benefit would be motor reliability.

It's good to hear that someone else likes trying out of the box ideas. I've been mulling a few over as well. Like strap on heat sinks for the exhaust header to help increase the lifetime of the exhaust. I know when I just took mine of it basically just broke apart... Maybe I'm just silly.

Btw I did manage to fit a cold air in my rx7 a long time ago. I'll see if I can find some pictures. But I can't really say its a true cold air. It simply relocated a KN filter away from the exhaust. Originally I was just driving with the filter cover off and the filter zip tied into the box..... Never again lol

 

this is whats bugging me. despite the fact that my engine really was about to blow and probably had quite bad compression, it seemed to run really well when we put on the rb exhaust and open air filter. it was a properly noticeable difference! and it had a really nice throaty sound. i cant see this project being "over" for a long time. seems like theres always something.. but thats whats fun about it!

 

No, I'm sure the intake air IS hotter...what I said is I couldn't feel a difference when I did that. It should run worse, what with the higher IAT, but it doesn't.
Least, not that I can tell.

 

it is indeed a phenomenon. because i had other things i wasnt sure about before, itll be interesting to see what differences i notice once everything is finally together and i can turn the key and hear some music by my favourite composer. (felix wankel) im also VERY curious as to what difference my lightened flywheel and porting will make. n/a maybe harder to squeeze hp out of but it is fun doing it =)

 

Clokker

Ah I understand you now. That is very interesting. I'm going to have to do some more reading on combustion dynamics.

Meerkat

I feel you man! I haven't heard that sweet symphony is a couple years..I can't wait to get her running again.

 

Me too! Nice 14hr shift today so ill be spending some time on here and casting about for New employment. Due to complications of the third kind ill be working till the End of the month and then I will be officially unemployed. I already have some leads so I probably wont stay that way for too long but I can use the time I get between jobs to install the motor/inevitable troubleshooting ect because I do not think I will have the opportunity to have as much free time as I had here. Aaah such is life...
