So I'm not so well versed in s30's, my dad picked one up two or three weeks ago and we've been working to get t back to being road worthy. When it comes to the engine he'd like to do a modern swap like a sr20 or rb26 in a few years but for now he wants to leave the stock l24. He really likes the look of ITB's but I can't find anyone that makes a bolt on ITB kit. Are the ones online in forums custom made or is there a company that builds them to order I just haven't found. Ideally he wants EFI and ITB, was hoping someone may be able to steer me in a direction that could help. Cheers!
