I’m from Norway (that’s why my english sucks) and i bougt a 1991 Volvo 240 GL estate for 4000,- norwegian kroner (about 800,-usd) matte black with tinted windows and a realy lowerd front suspention. It were ment for the scrapyard becouse the¥ could not get the engine to run. The engine is a beaten, stock b230f, a 2.3 litre inline 4 with electronic injection and a bad head gasket. Tikking valves as well, but te car were basicly free, and as an affort to get it running they had put on a brand new, comlete ignition system, new alternator and a new power steering pump. But the fault is somewhere in the fuel managemet system somwhere, so suddenly it get way to much petrol, and the engine chockes. (it did befour…) a buddy of mine got a bit broke and desided to sell me his turbo-kit for 240, mostly complete exept he didn’t have the fuel injectors and engine computer. So i got him some new tires that ended with a total price of 800,- for the turbo-kit (200$) then te transformation began 
I removed the complete stock exhaust and just bolted on the t3/t4 AR .50 hybrid turbo to the cylynderhead, mounted the volvo intercooer to the radiator mountings, used plastic strips to get the radiator to hang inside te ‘cooler and shortend the hoses about 10cm. Stainles pipes and silicone hoses: turbo-intercooler-blow off valve-stock intake manifoil. I were going to replace the oil filte anyways, so when i did i fitted a aftermarket gauge sensor adapter between the block and oilfilter and instead of a sensor i fitted a hose (oil filter on the rigth side, same as the exhaust/turbo) since there is pressure at the filter, and just draged it straigt ut to the turbo. Got some help for the oil return, we drilled a hole in the back of the block where you can see that volvo had some plans when they designed the engine. We hammered in a hose extention pipe whit some “tube gasket” on it and wolla! Full oil flow throug the turbo. I removed the cold start unit and pluged the manifoil hosing whit a wrench extention bit. Tok a garden hose over the engine from the oil condens recyceling to the turbo intake between turbo and te airflow measure sensor. The biggest problem realy were to extend the wires for the airflow sensor, since it’s located on the left suspention strut stock, but i now need it to be wedged in just behind the rigth headligth. I were suposed to have a power filter on it, regardless of what airfilter i try the engine stalls and wont start, probablye becousd te ecu fauld i metioned earlyer. Exhaust systeme were the only thing that i bearly got when i bougt the kit, got pipes for about half the car and it is 3" aswell, not pipes that people just have laying around, so i just tok the downpipe from the turbo and bearly welded on a 90’ bend so the exhaust want to escape out the side of te car, not throug the floor into te cupé. The pipe’s length is about 1.3m total out from the turbo, it comes out on te midle of the front passenger door 
nice sound. The fuel system is stil stock and broken. And god da–, how that car goes! Never been dynoed, and never will but there should be over 200 bhp! Bougth for a total of about 1000 us dollars and built in 2 days… Yeah, under the testdrive we naturaly blew the oil hose on the turbo, squrting oil everywhere. And the waterpump blew, so we glued it just to stop the leak. And sure, sometimes at high boost the engine misfires due too little fuel in the cylynders. And it’s a hell of a turbo lag, but stil… It’s a 1/4 months pay. And the only reason i tried is becouse my beleaves is bigger then my understandings. Just check on volvo forums. It can’t be done… A basic b230f have to high comp for a turbo. And you can’t have forced induction whit orange injectors, you must have the blue ones made for turbo. And it’s way too little exhaust resistance. It’s hopeles to put a turbo on a stock b230f engine… So why do my 22 year old, abused stationwagon with 299.900 km under it’s wheels preform a burnout to the rev limiter, standig still in 2. gear while boosting up against 30 psi with a broken head gasket then? Trust your self with cars. If you ask people that know what they’re doing, everything is impossible. If you are too stupid too understand that it wouldn’t work, you probable get it to work. Just as its physicly impossible for bee’s to fly whit their smal wings, but they fly anyway becouse they dont know that. True fackt! Please exuse my poor english, dysleksia, my adhd-way of “derailing” and my strong need to brief’n’brag hope someone enjoys this “so cheap and easy can it be” tekst, and that you too want to try to build a badass out of bad and ass
