To much bad news and broken parts, be positive!

[Liquid_Neon]

This forum has to much 'broken stuff' going on. lets cheer up! who went and drove around and had a good last weekend? It was sunny for me and i burnt my head cause i had targa tops off enjoying mah cadet!

[mdb4879]

Sad to say I haven't yet. But I may take it out sometime today or tomorrow. Maybe even take off the T-tops and hatch for some added weight reduction

15,000 miles since installation, my Ca18 is running better than ever. Drove it out to the lake for some mountain driving and swimming, couldnt be happier.

[nickhebert]

got my ca18 brought home from school and now its sitting next the my pit waiting for the swap.

[Liquid_Neon]

Another awesome topless cruise after work today. Drove nearly 30 miles all down the beach and the twisties to and from it
Stopped at walmart for stuff and when i come out theres a guy takeing a snap of my car. I say hi and he asks about the sportback :P
Got home and an older guy comes over to me and talks me up about the car too.

So much fun

Wen to a car show yesterday and raced a friend on the way back.
ahem... private road, cars are going slower then they appear due to loud mufflers (/disclaimer)
Well for some reason the video doesn't seem to want to embed itself here... use the link i guess.

Nice! I didn't realize you were running a high compression motor! And here I thought I was the only one crazy enough to do that, LOL. Are you on gasoline, or E85? I had problems with detonation on 91 octane unless I ran it really rich and pulled a lot of timing, which cost me a bunch of power. I switched to E85 and never looked back.

[Liquid_Neon]

Well there is 93 octane at all my local pumps, so i dunno if that helps much?
I am deff running rich, i pop flame on plenty of shifts. Plus i havent had a single problem at only 6psi. I am looking to install my boost controller and step up to 10 and see how everything goes. I'm quite cautious and only beat the car in steps. little bit, then a little more and so on.

I haven't looked into E85... if i begin to get problems maybe i'll switch? wouldn't i need to change stuff so the E85 wouldnt hurt anything though?

[float_6969]

Ah! 93 octane isn't available here at the pump. The 2 extra points is probably the difference between being able to boost a 10:1 motor and not. I know the few times I put 5 gallons of Toluene in the take and filled it up with 91 octane, I was able to lean it out and add timing and it pulled like crazy!

As far as switching the E85 goes, you need about 30% bigger injectors than what you would need for gasoline, a fuel pump to flow the extra volume (a walbro 255HP is fine for a lot of HP on E85), and some way to alter the fuel and timing to suit. To special lines, or tanks, or regulators. I've been on E85 for about 5 years and have had no issues.

[Liquid_Neon]

Maybe im crazy but i dont see a few points of comp a huge deal? People boost their KA's and a CA bottom end is tough as hell, so I imagine I should be okay as long as I keep the fuel count high and dont go crazy on hot days.

In other news, I got my idle all sorted out! Reset the TPS and got my idle screw set pretty good. my IAC seems to be working fine now that everything is set correct.

That's the smart way. Be nice to the pedal on hot days and you'll be just fine. I mean, I don't have a high compression motor, but high boost, hight EGTs and poor timing equals a rebuild regardless of what compression you're running. Everyday boost for me (though I don't use the boosted cars everyday) is at or around 20psi and that is on 93 octane in the wicked 90+degrees here in Miami.

[float_6969]

There is a big difference between the KA's 9.5:1, and 10:1. It's obviously do-able, as I had my CA on 91 octane for the first year after I built it with the high compression.

On a more positive note, I had been neglecting the CAS14, so I did some work on it this weekend! I got the PCV system hooked up, and my Grimmspeed Boost controller hooked up. Took it for a spin and found out that this turbo really wakes up over 10psi! I was on the street, so I couldn't get too crazy with it, but @ 10psi, I could easily break the rear tires loose from a roll in 2nd. And that was running a bit too rich and very conservative timing. This think will be insane at 25psi!!!

Work is starting to slow down, and once I get caught up, I'm headed to the dyno to get this thing tuned so I can start enjoying it again. I do need to replace the timing belt tensioner and idler pullies, as they've apparently decided to start making noise from sitting for so long. But I ordered a new set today, and should have that sorted out this week.

I've got some good news to add. My CA18DET is now located in the Pulsar's engine compartment instead of on a pallet. It's only being held up by the passenger and front motor mount though. I'm hoping to have the transmission and rear mount installed tonight. Axles and passenger suspension tomorrow night. I forgot to get the vacuum canister and power valve actuator installed before I put the engine in, mainly because I was excited to get it into the car. I'll figure out a place to mount them and hopefully I have enough room to do it.

[float_6969]

Dude! I just saw you have an 03 MSP! I've got an 03.5! Just bought it a month ago. Are you on Mazdas247?

Of course. I've had mine since 2005 and had a successful auto-x campaign with it in 2010 where I took 8th in class at the National Championship, last trophy position, but a trophy at least. The car is pretty old and busted now thanks to Rochester winters. My friend in San Fran has one (I introduced him to the car back in 03, I had to wait a few years to get mine) with 55k on it and he rear ended someone. He's giving me the car and I'm going to fix it up and sell mine.

[leadpaw]

Took the old ca18de sentra autocrossing, much fun was had surprising everyone and assassinating cones xD

Well after swapping back to my CA turbo, i have been smoke free! hooray! great news now is my exhaust is getting welded up so it should be done tomorrow! woot, got a flowmaster on the back

[float_6969]

nice!!! My car is running fine. Haven't driven it in a while though, been too hot here (no A/C yet). Still needs a tune and the boost turned up though.

[Liquid_Neon]

YAY! exhaust all in, only bounces a little bit :P one downside is now i can actually notice that even my CA turbo smokes, oops!! decell produces decent sized plumes of smoke.... oooh well!

muffler is some random flowmaster i dunno what series but it sounds quite nice! I'll record a vid of it soon and show it off... just ignore the smoke cloud that it fires out. one day i'll afford that T28 i've always wanted

[mdb4879]

Float: Panzie, I have three cars, none of which have A/C at the moment, and idk what the weather's like in Kansas but it surely isn't as hot and humid as it is here in Bama. Hot weather is what Nissan made windows that roll down for, silly, lol. Now go give your beast the "punishment" it deserves, after a good tune of course.

Neon: My car makes plumes of smoke when I decelerate as well. Does yours only do it when coming off boost? That's what mine does and best I've been able to figure is the rings are worn out. So when I'm in boost I get an excess of blow-by being forced into my intake tract. When the throttle is open there is enough air to burn it, but once the throttle closes that isn't the case and I get huge clouds of smoke. I think I remember one problems is one of the drains from the head (not in the head but the one from the intake side valve cover that goes to the big inlet right above where the oil filter mounts) doesn't drain/vent very well and excessive blow-by get puked out of the exhaust side valve cover under boost. Supposedly rather than running a small hose from the valve cover then making it bigger at the block you can make it big at the valve cover and run a big hose all the way to the block and it'll aid in preventing that line from backing up and reduce the puking of blow-by. I haven't done it to mine yet, but if I read right then that's suppose to help.

I think if it were your turbo it'd smoke all the time, right? Mine's a rebuilt stock t25 and I don't get any smoke other than coming off boost, then it's horrendous.

[Liquid_Neon]

well yeah mdb... that sounds like when it smokes.. but mine has fresh internals. i prolly didnt get the break in right, but it still shouldnt smoke from there unless something else got screwed up in there i cant see? I have noticed a puff or 2 from my pcv vent... i didnt think of this stuff....
haha... so much for my good news thread :P
I get tiny puffs at idle and decent visable trails behind the car on decell particulaly after boosting but it clears up after a second or 2 of cruisin.

[float_6969]

Kansas summer is at least as bad as Alabama. Very hot (triple digits almost every day for the last month and a half),and very very very humid (usually in the 90% range). Plus I work outside all day (I own a pool and spa service company) so I'm usually ready for some A/C when I get done with work for the day, LOL.

Try changing your PCV valve. If it's bad, it can pressurize the crankcase and cause lots of oil to get burned. Burning oil on decel is usually bad rings though.

[mdb4879]

Oh really? I didn't know that. I figured it'd be hot but I didn't know it got that humid over there. I've lived with it all my life so I'm pretty use to it, but it still sucks. Especially working outside as you said. It could be the same temperature, or even 10 over inside and it still wouldn't compare to being out in the sun. The sunlight on it's own just wears you out.

[Liquid_Neon]

Well despite all this smoke.... of which im more willing to blame my turbo as i knew it had problems. Sort of why i had bought that SR20 T25 which was great until it too smoked :P
despite all that, I have rather enjoyed driving the car all over again! Funny how much better a car runs with an exhaust. power is much smoother across the board and the flowmaster at the back makes for a really nice tone.
I had figured for a long while i was getting urbulence on the o2 sensor while driving so i was never seeing good reading and the car would spit and crackle a lot. on accel it wasnt a problem but it was really bad on deccels, poppin like whoa.
Tried getting a C4 vette to mess around on the way home from the store.. no luck :P
