hey that will be a awesome mod....i made 180 rwkw on 7psi and all i had was split dump, highflow car and 3.5" trust cat back.....sounds nice and yes its worth it and its safe even without a front mount....but once you get a front mount you car will run a lot cooler and better

Installed dump pipe (3" bellmouth, just jap SS $220), basic hi-flow 3"cat, SITC and R34 GTT 'cooler

had a 20awkw gain from 140awkw to 160awkw

already had fuel pump, adj.fpr, safcII, 12psi, that netted me 20awkw at the previous tune from 120 to 140awkw

IMO the r34 coolers arnt worth an upgrade over the r33, better off getting a proper front mount (you dont need to go massive).

the r34 cooler stayed on for less than half a year. using a return feed apexi fmic from a 180sx now along with a hiflow turbo, z32afm for 180awkw 14psi

dump pipe and good hi-flow cat will net 20rwkw

get it tuned right tho with each mod as you go along on the mod journey...

Finallyyyyy got my dump/front pipe and high flow cat done today, along with just the usuals, car sounds a fair bit meaner and the whistling is Alottt louder and comes in earlier than before :) , even tho i have a stock BOV and just an apexi pod i have been pulled over twice and tried to b defected and i keep telling em its all stock.......shits mee! And just my luck the dyno had a problem today so they were unable to tune it and stuff, goto love the timing :) . keep u guys posted on the total rwkw gain, really hard to tell just by driving it.

if you have same mods as me then you should be looking at a good 175-180rwkw.....and yes its a whole lot better now that you have aftermarket dump and cat as it will be more free flowing

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
