4g93 Mivec Turbo Waja project(Many pictures be warned)

13.2v is a good figure during idle.
no need to worry about your alternator.

Upgrading to higher capacity wont show better figure during idle as the current output is low at idling rpm.Alternator output graph is similar to hp graph of an engine.

Hmmm not too sure about that as I am also facing voltage drop during high rev.

Battery voltage is around 12.4 to 12.6, anything above 13 is still charging the battery

Occasionally it drops to 12.3v during high revs according to my datalog so yeah...

Some photos of the fans install

Have to smash that intake pipe when I'm back from outstation, still barely touching the fan motor.

Also replaced my oil pump during the fan install and the oil pressure like about the same only. Might be considering rerouting the oil cooler for shorter oil lines or try installing the pressure sensor at the sandwich plate as the current location of the sensor is actually at the head.

Poison apa? You also can ma.

Just ordered a bunch of Cusco LSD Mission Oil GL-4 75w85 because this is what's supposed to be used for FWD gearboxes requiring GL-4 with mechanical LSD. Pray no kena tax, and pray this actually smoothens the chatter....

Next project to remove the gearbox and set the LSD to a less aggressive setting...

Regulator cut the charging?

I also dunno, because apparently my 4 wire alternator, 2 wire go to ecu but now I using standalone, never sambung any alternator wire to ecu also.....

1.5mm gasket. Interesting thing is the brand of the kit is SOWA but the gasket itself have Mitsubishi markings :roll:

Copper-sprayed the gasket then installed the ARP head studs

errr... actuall that gasket design u not need to spray copper on it...

the black rubber/silicone on gasket perimeter is already a good sealant....

when u spray copper on it, then it will be easier for leakage...

Hi bro, thanks for your concern. Yes I do also somewhat agree that it should be fine without copper spray, but my mechanic here uses it on his builds and he recommends it. I personally think it wouldn't do much, but it shouldn't make it worse as well. Using the permatex branded one a d they recommend it for head gaskets as well so it should be fine. My previous engine build also use copper spray and it worked pretty well.

what makes you go for heatsheild vs exhaust wrap?

 

[Nightstalker1993]

what makes you go for heatsheild vs exhaust wrap?

Heat shield blocks heat by radiation completely and the heatshield itself would not heat up as much by convection(physically through hot air after being heated by the manifold) as there is a decent air gap between the manifold and the heatshield. Heatwrap may reduce the amount of heat by radiation but I believe it won't stop it completely and since the heat wrap material itself is physically contacting the manifold itself, the heat wrap material can get pretty hot itself although not as hot as bare metal. It may not be 800c worth of radiating heat, but 300c of radiating heat is still Alot of heat being emitted. Also, wrapping the manifold will be a beech and there are cases where manifolds crack after being heat wrapped, then again mine cracked without heat wrap...

Its not to say that heat wrap is bad, I just believe that heat shield is more effective than heat wrap for my specific application as my heatshield extends all the way to the side, covering the power steering pump and certain hoses. I do use heat wrap though, at the downpipe and the exhaust portion that's passing underneath my oil pan, and certain areas of my intercooler piping. And F1 if not mistaken uses both heat shield on certain areas and heat wrap as well so that can't be bad.

Check out this post, showing both heat wrapping and heat shielding. I do admit the most effective would be to have both, but in my application I believe the heat shield to be a better choice as opposed to heat wrap

My special order from the Land Of The Rising Sun had arrived!

Cusco Mission oil 75w85 GL-4 oil for my gearbox with Cusco LSD. Hopefully with this it will be silky smooth. Need to wait for my MIVEC gear ratios to arrive then I'll pour this in. This oil pretty much does not exist in Malaysia, even the official distributor here does not bring this oil in. GL-4 rating for FWD gearboxes with brass synchros.

RHDJapan is an awesome place to buy legit stuff from Japan by the way

wow.. how did you manage to ship this at a reasonable rate? The whole carton is yours? Sell me one?

 

[parakey]

The poison is strong with this one

6 bottles + Fedex Priority was only RM640 or so, roughly RM106 per can. Locally here people selling the other Cusco LSD oil at RM200 per can of 1L lol.

And why you need this? You're an RWD means you can use basically any LSD oil in the market with GL-5 rating. This oil is rated GL-4 specifically for FWD gearboxes.

Poison for what? I just share the happiness

Also, now i suspect my clutch master pump got problem, few times happened the clutch pedal biting point just dropped.... gahhh more time at the workshop

That's a verrrry good price. If you ever group buy something like this in future let me know please!

Nehh, I'll buy just enough for myself, because if I buy too much will catch the attention of the kastam.... And yes it's cheaper to buy from Japan than from the official distributor here

Kinda makes me wonder about fans and stuff too. Perhaps I could get an aftermarket fan cheap too.

Stupid wan. The normal Cusco LSD oil, which isn't suitable for my car, is usually sold at rm200 when on rhdjapan is around Rm80 only ..

That is why Tesco and Aeon Big can sell their oil so cheap, but lately Tesco no more.....
