there is plenty of info around you just have to use that search button but ill get u started

injectors you have options like nismo 550cc/740cc or cheaper sard ones which require some mods to get in or high-flowed ones from deutshworks or something

intercooler you will probably need something at least 600x300x76mm thick but preferably 100mm thick for that power

definately need an aftermarket ecu like power fc/haltech/microtech/wolf...the list goes on

fuel pump a bosch 044, nismo or tomei 500hp one

turbo im not sure but it will be pretty big not to mention many other things like afm upgade new clutch... the list goes on

just have a search and u will lfind

Don't waste the money you probably don't have anyway. Buy something that is already fast it'll end up costing the same once you've bought all the little unexpected's along the way. If you really are serious about it you should just import a modified front cut and just transfer the whole package straight over.

If your asking 'what turbo and what injectors etc' to use, do you really think you're capable of completing this project...

wat do you mean by no money, bro. i just wana get things right. i am seeking for advice not seeking for any trouble.there are a lot of modders out there, some ppl would prefer something is fully modded and transplant into the ride(i think this is ur kind) , some modders prefer to get the things done personally. coz learning from stage to stage will be a challenge.

i hope hope to get more info , n the correct stuff for my ride coz maybe ur right. iam not that person that have as much money as you !! i am new to this 6 cylinders engine , but i am not new for the street.

i applogise if i say anything wrong or hurt someone feelings, but i am just tryin to learn from all the seniors here

*peace*

      Unpeeling the Orange

      By MBS206 · Posted

      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.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
