late 97 on hilux 3rz turbo conversion walk through

[Tweak]

Just had the fella from road and track come out. He's saying big end has let go and piston is hitting head.
Shit a brick

[rodi]

compression test front to back 190psi 180psi 140psi 170psi....... Ive seen cars run on worse. All with in spec bar 140psi but there is to leak down. held it for a good 5mins.
Either way head is coming off this sat for a look.

Also somthing to make ya laugh. Rang a "engine rebuilder" to day. A few things to note in a conversation. "you will need custom forged pistons which cost $1300"..................I hang up after that

My bets on no3 big end failure and piston hitting head, anyone else

[Tweak]

Take ya Bets guys, First price is the damaged piston mounted as a trophy

[Tweak]

And your wrong. Piston has never hit the head.

Nothing so far everything seems ok bar a blown head gasket. I'll give you 1 chance to change your bets

Head is being checked and clearances re done at road and track by terry

A nats nad from taking it home in a bucket, can you see if heat has been travelling down the rod, could look a bit blue

Iam thinking its a leaking injector. and Its hydro locked.
To be honest i realy dont care to much as long as the crank its sweet iam all good. Was going to run it at jambo 2010 in august but i'll be luck to get the engine in by then let alone have it run
New rods,pistons(forged) metal head gasket, Ported exhaust, wack it together and on the dyno for a looksie at the tune and get it workable for jambo/normal travel. Then track down a decent computer and turf this adaptronic hunk of shit (out grown it already) wack in new computer (haltec or motec) re-tune to suit and iam going for 300rkw
So basicly iam going right back to the start lol

2 bent rods and a bent crank. Iam thinking boost spiked for some odd unknown reason



So any know of a good 2nd hand crank for sale

[rodi]

More like crappy rods mixed with a crappy tune

Have you looked into water/methanol injection to lower combustion temps? help you keep on the safe side and your standalone could probably control injection for boost, throttle position, etc. I plan on putting a turbo on my 3rz 4runner here in the states within the next couple of months and have been reading up on this site: www.customtacos.com sure you've heard of it. Mostly 2RZ on that site as its the standard for the 5 lug tacoma out here but I think there is a couple of guys running 50/50 water meth with good gains. Proper calculated mixtures can get you up to 110 octane and its cheap.

maybe you should check out the post in performance called " Ive got a knock"

[bajallama]

hahahaha, ya sorry I don't go to that forum much, I was just viewing over this section and saw this 3rz thread you started and thought I could help. I don't race my runner and its pretty much stock, it just tows my KP to the track.

Forged pistons
Forged Rods
ARP bolt kit
ARP head studs
Cosmetic Head gasket
Ported exhaust ports
LC engineering top end kit (cams,adjustable cam gears,larger valves,valve springs,guides ect)
LC engineering lightened flywheel
Custom NPC clutch (again..... It appears the first one is not worth putting back , loose spings)

Thanks to terry at road and track.
