And stops with small amount of throttle .

Hi mate and welcome could you pop over to the intros first before asking questions
just polite and all, no harm done just something the forum asks of us all
As for you problem did you know what your boost was at that time or what your EGTs were.

1 is bad enough but 2 man that's scary hope you get it sorted soon

Where did you get the 2nd motor from? Or was it a rebuild?





….................... On the move

I think your intercooler was leaking creating low boost
which inturn gave you high EGts then bang 3+4 melt

Is your IC oily????

G'day and welcome to the forum. Recon you should be talking to whoever you got the second motor from.

Back again landy96 has started dementia so any help would be very apriciated so had trouble startingin site with password etc so intro location photo etc washard to work out .sorry for that. Cant find profile settings .
No gauges when 1st blew .yes intercooler is oily . 377ooo on clock .currently no reading on boost gauge ? 2nd motor was bare .told recond 25k kms ago .most of old motor parts refitted . Maf cleaned. Idled better with thingy underbellow maf disconected. So cleanedit to but doesnt idle better now.

Problem solved the guys at on track 4x4 slacks creek sorted me out . Stupid maf sensor made my car run like crap and the belt adjuster was bouncing around for hoffible sound . I bought a cheap one 2 months ago and it just died. Bought a dear one from autobarn but it doesnt feel any tighter ??? Thanks guys for the support and thanks ontrack 4x4 for great service ..cheers ..

Glad its sorted an easy fix this time

Good to hear it's sorted. Stick around, plenty if great info on here.

Thanks for that .just trying to sort out settings for dawes and needle valve now . Looking on sight .and alls good .cheers

Slight problem cant get it to run quite right setting dawes valve ? Also makes wind noise trying to get boost up currently under 15?. I fitted dawes and needle valve.i set the dawes at six turns out to start with and needle valve closed .went up slight hill and turbo went to 20 very easy with heaps of power on low revs so reduced 2 turns on dawes . And after much stop starting adjusting i cant get the boost up to 15 the closer i get it looses power and makes a very loud wind noise .its runs better and no wind noise between 5 and 10 boost it wont go any higher. Also tried adjusting needle valve as described on forum and random .does anybody on southside of brisbane know how to set these please.. cheers

Thanks everybody . Mudski has sorted me out. Cheers
