just wondering how long this motor should last kms etc before i should look at doing something ?? i just bought the car and was wondering thats all cause i dont want to break anything some help would be much appreciated

thanks.

ENGINE: *CP pistons probs more but cant think !!

*Eagle rods

*N1 oil pump

*Tomei sump baffles

*Tomei headgasket

*Tomei oil feed restrictors

*custom oil drian from the rear of the head to the sump

*balanced crank

*acl race bearings throughout

*N1 water pump

*Apexi cams ( not sure what lift)

*Aftermarket vavle springs

*Hks cam gears

*Hks timing belt

*Bigger Fuel pump

*700cc sard injectors

*adjustable fuel reg

*Nisstune ECU

*twin Garrett 2860-5s

*Huge intercooler

*Alloy radiator

*Front sway bar

*middle sway bar ( in photo of interior)

*rear sway bar

*Bilstein coilovers

*torque split controller( not working at the moment will try to get fixed before sale)

*drilled rotors

*gauges, oil pressure, boost

*Alpine headunit

*Alpine 6x9s

*oil filter relocation kit

If it was built right it should last as long as your usage implies.

If you pump your -5s to max capacity and run it on the knifes edge on the track every day of its life, you will get about as long a life span as you would any other race motor before it needs rebuild (not very long at all). Yet if you were to daily it and take exceptional care of it I anticipate it would possibly last as long as a factory built motor.

I would probably change that N1 oil pump to a Nitto or JUN item though, that is the weakest link at present.

The only way to know would be to strip it down which kind of defeats the purpose.

Who knows it could have been slapped together on the grass in someone's back yard with all the tolerances wrong and it might last a week, it could have had everything done perfectly at a shop and then run with no oil, or everything could be fine and it could last 100,000kms?

the speaker part was not ment to go in i just pasted and copied page lol...

the oil pump is it really a problem i drive it maybee 3 times a week and i dont thrash it everywhere i go. everything feels tight

it currently makes 314 kw but has made 450 kw with the old ecu that was pfc it now has a nistune because of defect

well.. if its lasted 3 years and is still running sweet today, not burning oil etc, im sure its been built some sort of standard - but as said earlier, it could go bang 2moro or could go for another 5 years - too many variables!

ok apparantly it didnt... saysss im just goin off what the original owner that built it from ice performance told me................................ thats all im not making up shitttttt if thats what u think

do u have any proof that the engine is even built? or did he just hand u receipts from when his friends, friends built a motor.

common misconception is that building a motor gives u fully awesome big power, when all it does is make the engine components stronger.

sure u can make 650rwhp and the motor will last 12months or you can run the same motor at 300rwhp and last 10years

  • Nope 1

do u have any proof that the engine is even built? or did he just hand u receipts from when his friends, friends built a motor.

I'd be thinking a similar thing.

If it was from ICE down here in Vic, I'd be even more worried... There were plenty of no-so favourable experiences that myself and several friends went through before they shut doors.

Defensive much? Perhaps those posters are thinking that whoever told you it made 450 is a liar, and therefore you cannot trust anything else this person has said to you.

Also

*middle sway bar ( in photo of interior) <= WTF??!!

*torque split controller( not working at the moment will try to get fixed before sale) <= if the controller doesnt work it will be taily but still put torque to the front wheels. If it doesnt, it could be expensive to fix.

*drilled rotors <= likely to crack with track use

    • @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.
    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
