Yup, also might be a leak somewhere near the MAF.




What MAF is being used?
I know when my Z32 MAF begin leaking the car ran really rich and rough. So rich that the plugs would foul out.

 

I'm using maxima MAF . I dont know why I have to change it to Z32 MAF .

and I'm sure of that there aren't any leaks . I did something like haidrotest to all the pipes and it was holding the presure . I did also comparstion test and it was 90psi on all pistons .

but there is one thing I will do but I wont tell you what is it until tomorrow .
until I get the result .

 

90psi?

It should be closer to 190psi on each piston.

 

I dont know but my pistons are low comprastion

 

I commented in the youtube clip but there was no reply. I asked if you used a torque wrench to put the engine back together and if you torqued to specs because it looks like you were just tightening bolts. That possibly could be an issue.

 

Tq wrench. Watch video and listen for click. The assembler memorized the Tq sequence.

 

yeh . if you concentrate you will see hem torquing . that was a torque wrench . and he was torquing as per manual for sure . you can here the click at the end of every blot .

but I'm worry about the temperature . it is between 200F and 210F . the fans starts at 210F . I want to keep the temperature about 180F if I can .

I will go now to the work shop . I will back soon

 

Any codes? Can you plug a obd2 scanner? Is the the check engine screew on the engine control unit is set at the right place?

edit: Are you using any ecu upgrade what so ever? (stand alone, piggy pack, reflash)
Also what injector size and what fuel pressure?

 

the problem has solved finaly . I have SAFC attached with the ECU .
it was running on the sitting of the old engine and it was lean .

I Adjested it a little but need more adjusment . my mechanic will do the right adjusment with his portable wide band .

thank you guys . more to come soon ^_^

 

Very nice! Get us an updated vid when you can.

 

thanx and I will .

I got exhaust leak . I got creepy sound . I need new mufflre . EVO 2 sounds perfect . do any of you got new one or used for me ?

 

guys adjusting Air/feul didn't end the problem at all .
the last thing my mechanic did is a timing test by his timing light gun .

we will open the chain cover and make sure of cams timing

 

Just before putting back the outer timming cover, use a ratchet to turn the crank. Watch the timming marks as you turn the crank. Turn it until the marks allign again to make shure the chain did'nt skip a toth.

 

I will but my mechanic is busy . I have to wait my turn

 

good day guys ^_^

we opened the chain cover . we found that the front cam chain is one toth behind the intake cam gear . the brons part of the chain is not in right postion .

unfortunatly i didn't get my cell phone with me so I didn't take any photos


today at the sunset it mey finish . and then we can drive it for training ======> to go on boost .

I will drive it on low boost in order to become accustomed then rise the boost a littel bet and so on ....... until i become fully accustomed with higher boost .

BTW is there any alternateve for nissan red silicon ? it wasn't dry from inside

 

guys how to convert from LBS to PSI ?? I did a comprestion test after the timing adjusment and it shows 90 LBS !!! I was wrong in the old reply

 

Black silicon

And wait at least 24h before puting any oil or antifreeze/water in the engine.

 

PSI is LBS. Pounds per square inch.

 

we dont work in Fridays . we will complete it on Saturday . we used Toyota red silicon . it is cheaper and better than Nissan's .

 

OK guys here we gooooo


http://www.youtube.com/watch?v=XMj_E2YnEHk

it's a little bit dirty . i need to clean it .
now I will do some maintenance works . I have broken engine mount , some broken shocks mounts , wheels and steering wheel alignment , and replace some broken wheels bolts .

this work may take 2days . after that I can drive it safely .

 

That is a nice looking setup. Keep up the good work. Can't wait to see more videos of it running on the road.

 

Do not rush my friend ^_^. me too I can't wait to drive it but I have to get rid of all the problems .


guys , your opinion please . more posts please .

 

Buy parts and fix the problems, what opinions do you want?

 

Isn't it better to keep the bov before the maf? So when it vents it doesnt go rich?

 

Regarding Silicone: Just get whatever. Black RTV will do the trick on most anything. High temp red is a rarity. I've maybe used to enough times to count on one hand in the last 8 years...

 

mmmm . I see . when the bov vents, some of the counted air will go and then it will become rich . my macheanist made it like that . I will tel hem .

thanx kevlo .

guys what do you think of Greddy touch informeter ? advantages/disadvantages ?

I am thinking to git Greddy e-manage Ultimate only if I can get a harness that fits on my ECU . its different not like your maxima's ECU .

 

You sure? I thought we had the same ECU connector but you guys just had OBD1 and 1 o2 in the front.

 

this is our ECU



and this is yours I think

 

Wow, did not know that. All the cefiro ecu's I have seen had the USDM style ecu but with less emissions stuff.

I doubt you will find a plug-n-play harness for your ecu for the EU. But the EU is not that bad to wire in, it will take an hour or two to solder it in. It is a MUST imo to tune a boosted maxima safely.

 

Get the e-manage. If you were capable of having all these things done so far you'll also be able to install the e-manage.

 

actually your ecu is similar to VG30 and SR20 ecu's, you might find a p-n-p harness for those and mod it for your ecu

 

Or if you are feeling creative, you can use this:

http://www.nistune.com/equipment-products.php

 

before around 5 monthes , I installed e manage blue . but it didn't work . my screen tells that there is a connection error . so I returned back my SAFC.
but I don't like cutting wires , shrink and soldring ....... so I have to find a plug n play harness that fits on my ECU .

or I may get one of JWT's or send my ECU to him , but i dont trust JWT .

I sent a messege to the site that you add . I asked them if there are bords for maxima , cefiro and I30 all A32s. I will white for their answere.
they have for Y33 (VQ30DET) I dont know if that one fits or not .

 

Yea you will likely have to send them a picture of your ECU, prob the inside. I am 90% sure you can use those Nistune boards(I think we can too but I dont have 400 to experiment)

 

safc< vafc< emanage blue < emanage ultimate < standalone

wires<wires< more wires < even more wires < the most wires

 

 

I for got to send them the pic but I got there answer


Sorry
it doesnt work on those vehicles. I have an A32 maxima ECU here but1997 model to get working on the Type 4 OBD-II board. Other later models areprobably FLASH based ECUs.

I didn't understand any thing

LOL

 

BTW they are from Australia . I dont know what kind of ECUs they have on their maximas. but their maximas are like our mid eastren maximas .

I hate nissan becouse of this .... but I love my max ^_^

 

Yea he is talking about the USA maxima it seems like. Show him the picture of your ecu connector and see if he says anything different(like if he wants to see the inside of it)

 

I sent the picture . I will be whiting for thier answer.
tomorrow I will take the car out of the shop finaly . I will drive it only for
1000KM then we will go for boost and dyno.
