It's aviation High-Speed aluminium tape, costs more than rm100 per roll bruh, no issues surviving 90 odd celsius :laugh:



what? Now that's something I never heard before actually...
Oooh! aviation tape......:driver:

Yup, when my old turbo leak oil from the shaft, send in for repair they found the header cracked also, so I opt to replace with chop shop whole unit. Heard from some is common problem.....:banghead:

Yeah, that tape is designed to survive being applied on the outside of an airline aircraft and survive, which is why they call it speed tape. 3M punya :biggrin:

Well standard cast manifold should be quite cheap and easy to find seeing how most people just chuck it away after swapping to pisang :laugh:

Hopefully can collect my SPAL fan later today, and stick on some proper sponges to prevent air leakage and make sure all the air actually passes through the condenser and radiator. Also time for my car to service and change the oil pump which I already standby, and fix that cracked manifold, and possibly change the turbo actuator spring to something stronger :emoji_muscle:

My radiator fan plastic cover/housing have become brittle and a piece have chipped off. Wonder if the tape can help?....hmmmm

Well if it had become brittle and broken off at some parts, it will start to get brittle and break off at other parts as well not long later so might as well just change fan casing or fabricate a new one. But my advice is if stock fan can fit then use stock fan saja, want to find aftermarket fan that can match the flow rating if stock fan is actually quite hard to find and super expensive :Stupid:

Apa mau buat, mod car life like that lorr... Radiator fan because stock standard fans can't fit anymore and the AVS fan I bought last time was a disappointment and waste of money, manifold crack for god knows what reason, need to add sponges because radiator changed so the gaps and spacing all different, oil pump change because 4g9x famous for oil pump failing so I want to replace the oil pump that came with the halfcut with a brand new one as preventive maintenance. Turbo actuator spring mau tukar because current spring only gives me like 0.4-0.5bar spring alone and using boost controller to bring up the boost already requires almost 80% duty cycle to maintain 0.8bar, 1 bar and above should be quite hard liao :bawling:

Radiator fan still going strong. If not mistaken changed once only and was a chop shop unit. Air con fan changed a few times and now even chop shop cannot find so mechanic modded another model in. Radiator fan is in the front, to get at it must remove grill and bumper....:banghead:

Oh you got a pusher fan also? From evo ar or Nissan? My gap too small to fit any standard pusher fan, only got 67mm of clearance, no choice but to go for SPAL, even that also I cannot choose the high performance one, only the mid spec one can fit

Use stock fan, all OK.

Stock fan brand new actually not cheap weyh actually, looking around online, brand new evo fan assembly is like 3xx-4xx USD weyh, see those stock fan motor also damn huge. Only change to aftermarket fans if you really have to, and make sure you buy a SPAL and not those cheap RM200 fans which are pretty useless. Even SPAL also got level punya, get at least the mid-high end model with 1000-2000CFM at 0inhg static pressure, of course if budget and space permits just get the largest and most powerful 2000cfm one terus.

What oil pump you gonna buy? Like me buy brand new is around 1.6k plus taxes and shipping weyh :bawling:

Install oil presure gauge first.

Mine is original air con pusher fan. On the inside, Radiator fan takes up space on one side. The other side got alternator, power steering pump so is limited space, so they put it in front behind the grill and bumper......lol

What intercooler you using eh? Mine not enough clearance to fit those std fan, only got 67mm clearance only.

well, it's luck la some people drive many many many years no issues, some people build engine masuk dyno then kong. I would suggest just installing an oil pressure gauge with low pressure warning alarm and monitor it lorr. Cheap insurance for your engine.

Anyway, some updates. Just bought a SPAL 'Medium' strength 13" pusher fan with a depth of 62mm only and rated free flow rate at 1186CFM and a more realistic flow rate at 0.4inh2o at a pretty decent 826CFM. Hopefully this will solve my heat issues when idling under the hot sun.







Also just received my free 7" tablet from signing up for Standard Chartered credit card, now I got a new assistant when driving/tuning :biggrin:


Will be sending in my car to workshop later today and will start work tomorrow on the oil pump change, fan change, bushings and removal of the manifold to reweld the crack.

nice display...do u use can bus shield to display at android or ur waja has obd2 port?
No man, I'm running a Megasquirt MS3x standalone and there is an app made by some guy to interface with the ECU and also do minor tuning and adjustments on the fly. Connected via USB OTG to the ECU's built in Serial to USB converter.

You can see it in action during my last track day with a 6" phablet haha

The reason I start this thread is I've notice for a while now since 2007. Most car that are stolen or break in are either those car that took part in Autoshow , appears in car magazine before or are well known around a certain area due to it's specialty like it's fast or got some goodies inside the car. I'm saying this by seeing the real things that happen and not guessing.

Autoshow can be a chance for the thieves to see what's in your car much more better and know every bit of things you...
