what the fugg is wrong with my car?!!

[r34 gtr]

ok, i finally got my turbo rebuilt and back on my car, with a new nissan water pump. i drove it for the first time since this today. im about 5 blocks from my house and guess what? you guessed it! my water mump exploded. now, this cant be right. both times the water pump was brand new. i dont have a clue why this is happening. i will never be able to drive my car. ive only driven it 3 times since i got the car in october. my question is, WHAT THE FUC/< is happening to my car? i might try new pulleys, but i dont think i have enough for aftermarket ones. i really want to know, IS the ca18de water pump EXACTLY the same as the one on the det? im really upset right now. please, anyone, help me. im so confused.

[r34 gtr]

also, the belts were tensioned exactly to the fsm's standards. and it was running like a swiss watch. no problems at all until the water pump sheared in half

do not get the cheap auto parts store replacement, these have been known to shear in half...go with a dealer replacement...

[ca18datsun510]

read his post. he just said he got a good one.

[slw240sx]

damn, for reall just sheared in half, i got to see this, can you post pictures

[SxMachine]

I have one thing 2 say http://www.sxoc.com.

[slw240sx]

ahh yes, the good guys on the brit board have plenty of experiance, and all are very great at helping yuo out when your stumped !!

[r34 gtr]

ok, thanks, ill try asking them

[nomore_mr2]

or you can do it the easy way. gut your stock water pump so you can still use the factory belt and get a inline water pump(electric) and run it in the bottom rad hose. this will not only be more affective in cooling but also frees up lost horsepower. its an old v8 trick which i have done to mine.

[r34 gtr]

hey, thats a really good idea, wish id thought of that earlier. i will definately try that, buy first i gotta fing some new pulleys because of a rabid fan with a water pump pulley attached eating all of the other pulleys before melting onto the crank pulley. i dont think theres one left that wasnt royally owned. will pulleys off of a ca18de work? if not, anyone else got some i could buy?

[slw240sx]

hey where can i find an electric water pump

[Bizz]

Hmmmm what if there is some major obstruction in the coolant passages? but i'm sure you've flushed the system already.

[nomore_mr2]

well starting with a brand new motor new hoses new radiator i didnt have to worry about that. as long as you just flush everything you should be fine. let me dig through receipts and find out wher ei got my pump. they are about 200 for a good one. its also nice cuz while your at the track on a warm day just turn your key to the on postition and it will cool your engine down without starting the car. keeps things nice and cool

[r34 gtr]

hm..$200, i might be able to pull that off, i just wont eat lunch at my house for a few weeks(gotta love rich friends!). my engine is almost brand new, and it was checked over, so i dont think it could be collant passages, etc. i also flushed them. even if therewas an obstruction and i didnt get it out, i probably would have noticed it when i looked at the damage to the pump. im not so much worried about replacing parts, i just want some ideas about what is wrong with my car. ill try any suggestions, and if you could find out where you got that pump, it would be great. thanks! - tim

I just got through completing a 240SX with CA18DET and he's using the stock fan and so far so good, but I would do away with the fan clutch stuff and go with a set of aftermarket units. Electric pumps on an everyday ride is not the best thing especially when you're not the one doing the work. I don't know much about them, but I would hate to see what happens when your alternator or stereo put a wicked load on the batter or vice versa. Here's a pic of the finished motor with SDS efi system =ed a happy customer.

[nomore_mr2]

damn that looks great boost boy. good job!!! my friend with a twin turbo vette that i helped design uses a electric water pump. hes the one that recomended it to me. he has no negative side affects in using. they are rated at like 2000 hours of operation though so changing them is going to be inevitable.

[r34 gtr]

hm...that pic doesnt look like it has the cas on it. how did you pull that one off?, congrats though, it looks almost as clean as my engine! (the only reason my engine bay is so clean is because of my dad's little obsession with spray paint)

Quote »damn that looks great boost boy. good job!!![/quote] Thanks man! Unfortunately, I feel it could've been better, but the guy was working with no bidget whatsoever. He had someone wire up his standard CA18 harness and ecu and they botched it up horribly. My thing is "Do not mess with what you don't know". The car wouldn't idle, wouldn't rev past 1500rpm, so to save him some money and headaches, I offered my last SDS system to him + installation for a nominal fee. He thought it was a deal of a lifetime and jumped on it, but he still has a sorry TurboXS BOV (the small one) that leaks at about 3psi, the stock side mount intercooler and stock injectors as well as the stock turbo. it rides nicely and that's all. Anyway, electric water pumps are cool to have especially if it's a bee-with-an-itch to get to like the CA18's. I guess overall, it's not such a bad piece of equipment to have now that I think about it:icesangel

Quote »hm...that pic doesnt look like it has the cas on it. how did you pull that one off?, [/quote] The car now has a standalone system which basically eliminated the AFM, CAS, idle contril unit and a few other things. These engines seem to love this system! I've installed 4 so far, but this one possibly was the hardest because this is the only one that uses the stock injectors whereas all the other used 550cc or greater, so tuning backwards felt kinda awkward, but it was tuned correctly.

[nomore_mr2]

boost boy,i have been thinking and when the time comes would be be interested in tuning my ca? i'll fly you up here to help with my tuning. yyou seem to know this engine and sds better then anyone. i would gladly pay you to come. dont worry the snow will be gone by then lol. wouldnt wanna scare you.

[boost_boy]

I'm game man! Thanks for thinking about me and the snow because snow is "No-No" . I wish I had bought this system 1st before screwing with JWT. I mean I spent alot of money and was not as impressed as I am now with the SDS and it's actually fun to play with. My boys at B.Y.P. prefer the haltech or a DTA and they kid me about selling all SDS systems and I tell them basically to go to He**. Did you make the bracket and have your pulley marked for the magnets? If not, let me know because I could ask them to weld-up another bracket and I can put the magnets in your pulley.

[JDM_1990_S13]

what are you using to trigger spark if you are not using the Crank angle ssensor?? a distributor?? not seeing one there, come on share with up please boost boy

[JDM_1990_S13]

ok i see i think it uses a crank triger right? you put it on the main crank pully then, and i see the external coil packs on the front left hand side behind the lights. ok ok.

[boost_boy]

This system uses a Hall sensor which has 2 eyes that senses magnet pulses from the three tiny magnets that must machined into the pulley. Here's what my set-up looked like on my sentra.

[nomore_mr2]

boost boy,it looks like may would be the perfect time to get here. snow will be melted and the last of my pieces should be arrived and installed by then. i havent even touched the sensors or anything for the sds. so if you want your boys to make me something just tell me how much and i could use your magnets and i'd be set then. depending on how much time you would have we could wire up the sds and then bring it to the dyno. its up to you. i just need til may before i am ready to start it. i just bought a full out tomei engine but i am not keeping the 2l block. no way to ship it here. but i did get a tomei head with 280 cams 10mm lift solid conversion lightweight valves port work springs. the works. also i found a t51r for under 600 a kai so i gotta have a manifold made for that. then i am in business. but i never see you on aim anymore. if ur on im me and when can discuss you coming up here. thanks

[boost_boy]

My Bad mr2 as far as AIM. You have no idea how many different people attack me for info when I log on. I don't mind helping out anyone, but unfortunately, I can't give sound advice to everyone on every topic at the same time. Heck I used to type pretty slow, but now I'm lightning quick Guys, when you want to just rap with me and see some videos of the old car, just email me at [email protected] and give me a time when you're going to be on AIM and be sure and leave me your AIM handle because some people are going to get ignored if you don't carry a CA18DET or interested in buying some gear. The CA guys are okay, but I also post on another forum and sometimes they just wanna talk about current evens and I really don't have alot of leisure time.

[nomore_mr2]

yeah boost boy i feel you. i do the same thing. for about amonth i blocked everyone except the people on my buddy lists. aim just gets to hektic otherwise. um if you dont have my handle still(been awhile since we talked) i'll email it to ya. oh yeah i was thinking any chance boys at byp could make me a turbo mani to fit this t51r? it has a 100 or 115 mm inlet vband flange. them seem to do good quality stuff judging by the pics you posted and you know how it would have to fit in a rwd car set up. anyways i'll shoot you a email and we can discuss things

[boost_boy]

Cool! We'll talk..........

[slw240sx]

speaking of you guys hiding out from AIM. . where have you been damn ive needed to talk to you Nomore. ohwell ill get to talk to you sooner or laterJon

[Bizz]

which sds system do you generally use on your motors boost_boy?
