3sgte into NA SW20 mr2

Hey guys,
Hows it going? As you can see i'm the new kid on the block. Anyways more to the point. I've recently purchased a very cheap 1990 NA sw20 mr2 through JSPEC imports..I got the car for $5800, about 8k on road...It's in good shape apart from the paint work..heres a pic 
As you could have guessed i've been bitten by the modifying bug and have decided to upgrade to the 3sgte...Although i'm after quite an angry 3sgte (250rwkw) and want to get it right the first time..So i was wondering if this was a good plan and if anyone could hook me up with some recommended mechanics, suppliers etc..
1.)i want to upgrade the turbo straight off the bat so I heard that buying a 3sgte engine without a turbo would be the cheap way to go?
2.) rebuild + new turbo...pistons, rods, cam shafts, cam gears, valves, rings etc...(i'm not actually too sure on the internal strength of the 3sgte so if any of these parts wont need upgrading for 250rwkw tell me please)
well thats about it..i want to get the engine and rebuild it soon so its ready to be whacked in the car when it gets here...my budget for the cost of the engine and the mods is about 6k...I know it's not a massive budget but im hoping it will cut it...
What other things would i need for the conversion? All info would be much appreciated. i'm reading old threads for info but would like my own in here too..
Cheers guys

I hate to be the bringer of bad news but I doubt $6k is going to be enough for you to see 250 rwkw from a 3S.
Lets take a look at what you're going to need, just the basics. These are only very approximate prices.
Turbo - $2000 for a GT less for an old school thing
External Wastegate - $400 for a tial
Exhaust Manifold - $600+
Water and Oil lines for turbo - $400
Dump pipe - $400
Exhaust - $600
Upgraded intercooler - $500 for a second hand upgrade in the stock location to a couple of grand for a new water to air
Bigger fuel rail - $300
Bigger injectors - $800
Upgraded fuel pump - $200
Upgraded Clutch - $600+
Programmable management - $3000+ including install and tuning
Cams - $1000+
Cam Gears - $350
Then you still haven't bought the basic engine or had it built strong enough for what you want. You should also look at doing something about the standard intake manifold as it has some serious flow balance issues.
On a brighter note there isn't really any need to upgrade the 3S rods for the power you are aiming to make.

Ok well thats a little depressing...Double my budget lol...I wanted to do this without taking out a loan so..What would be the best modifications for me to do with about $6000?
1.) buy a 3sgte half cut
2.) basic rebuild..rings, valves, etc..i guess the big parts will have to wait till later..
3.) exhaust
4.) upgraded cooler
5.) boost controller
Would that be a good way to spend 6k? Or can someone with more experience send me on a brighter path? I don't mind having to use good condition second hand parts.

Thanks for the advice man. Can anyone here from around the Sydney, Newcastle, Central coast area give me the name of a recommended mechanic to do the conversion? I want someone who has performed a 3sgte into an NA mr2 before..

Save the money [6k odd?] and try to source a gen III rear cut mr2 engine. That is about the price range they go for and what you'd get is the 184kw engine variant, rounded tailights, turbo engine lid and the lsd gear box. 6k should be enough for the rear cut. However sourcing one is a biatch, and you may have to go to an parts importer to source one in japan for you.

Luc146 i have finnaly achived that figure and from what i have done that 6k i would say changed it to about 15k - 18k i say this because with that much power expect problems... u will need to get a lsd gear box $$$ and then most likly rebuild $$$ then u will have issues with CV's more $$$ you will have to get the iners strengthed parts. list goes on and on. im not trying to talk you out of it cause that much power in an mr2 belive me is friggen unbelivable. just be prepared for problems and lots of money. I wish you the best of luck.

That does sound like a nice option..But i think i'll take this gen 1 half cut that i've found. It will be enough to keep me happy for the time being i think. So once again, can anyone recommend any mechanics?

CVAP(forums sponsor) was selling a BEAMs 3SGE($3800 SW20 half cut) on here a while ago, not sure if it's still for sale, but you could ask, that would be a nice 200ps N/A conversion, and possibly save you a bit of money with the extras that Turbo's add

sorry luc my prices was the cost for you doing the conversion yourself.
I did an engine swap when all i knew how to do was change the oil and sparkplugs.
When i did my conversion in my aw11 i bought a low cay half cut and simply transplanted everything from half cut. I learnt a heap and i could do it in a quater of the time it took me last time.
If you were gonna get a workshop to do the converion expect 3-5k as it is quite labour intensive. However if you do decide to do it yourself then pm me id be happy to lend a hand.

i can't recommend BD4's for any conversion they have ever done.
i dont like them, i think they overcharge and cut corners like you wouldn't believe. I would consider doing this conversion myself, but dont really have the time and space atm.... my housemates would probably get a little annoyed - considering there are already 3 project cars here!!
just do it yourself. there are heaps of mr2 forums which have massive amounts of guides to doing this conversion.

Thanks for all the info MR.2 i didnt see your post this morning. Well from what you've experienced it looks like i'll be waiting until im at royal military college in canberra before i start throwing that much money at it.
By the sounds of it everyone is recommending doing the conversion myself..i was thinking that but didnt know how difficult it would be as i'm not overly experienced with things like this...Does anyone have any conversion guide sites that would be helpful? If so please post up ASAP
4agte i'd love a hand i'll PM you now.

I've got a SW20 Turbo I'm parting out, I've listed it else where in this forum but just incase you missed it, i'll tell you about it.
The car is crashed damaged, spun around against something like armco, so the damage is not to major and has not involved the mechanicals or the cabin but has damaged most outer pannels (except for the passanger door) and nolonger has usable chassis numbers, so i'm parting it out.
I've still got every thing need for a NA to turbo conversion.
Including the strong turbo gear box and axles.
Also other items like Turbo engine lid, to make the conversion complete!
So basicaly I can offer you what you would get from a half cut place some extras like factory turbo Dash with boost gauge, front brakes etc.
Plus you can here it run as it is still all complete.
I'm also from the outter Newcastle area, down near Toronto if that helps.
anyway email me if any ones interested:
Mr2parts@gmail.com or if that doesn't work gives us a call on 0416 236 012
