Heres some more info for you. Na 2j block have been known to hold 800rwhp on a stock bottom end. Na heads will still flow better than a ported tt head with 1mm oversize valves. There are guys making over 700rwhp on stock na intakes and distributors. Stock 2j injectors should hold 400rwhp no prob. Im running the stock rail and regulator with an in tank 255 walbro. Most people dont think 400 rwhp is alot until they experience it. When u can break loose 255 tires going 60mph is sometimes sucks lol. Try screwing around with someone and not being able to go anywhere and just spinning tires lol. I would be willing to bet you could refresh and get all the needed parts to turbo you 2j for under $3000. Are you currently auto or 5-speed? If you stay with stock injectors for now a SAFC 1 or 2 would be plenty to adjust fuel for you. I would also recommend a wide-band. Innovative LC-1 and gauge best bang for your buck, awesome wideband. Me and all my friends use them, no regrets and really nice quality. There are so many 2j parts on the market now that used or even new parts can be picked up for extremely cheap. Im running a knock-off manifold, just make sure it has no lag in it, the flanges are straight and it has the braces on it and let it go. Mine was used when i got it. 2j na-t ftw best thing i've ever done to my car by far.
