I’ve had my 2wd 94 pickup for a couple years now and I’m starting to build it into a street truck and I’m looking into options for engine swap and at first I wanted to fully build the engine and turbo it but I’ve seen a lot of threads that it’s not too reliable so I’m straying away from the turbo build idea. I’ve been researching the sr20 Nissan 2.0l 4-cylinder turbocharged engine or a 1uzfe 4.0l v8 I want around the 400-500 hp number.

I know guys make that power pretty reliably out of turbo'd Honda K series engines.
Or you could just cram a Chevy LS in it

LS is always an answer to the problem and honestly a turbo k series wouldn’t be bad at all would definitely be a lot of work for a rwd k series but I’ve also heard Honda might make a civic type r in a rwd configuration

The first version of the 1UZ-FE was 256Hp, the vvti models were listed at 290, but the Lexus GS400 was listed at 300hp. You can get amazing power from these engines, but to move above your lower limit of 300, it's going to take some work and $$$. Also once you get into the late 97 early 98 years when the VVTI was released you are also dealing with the immobilizer circuit that needs to be bypassed. there are a several mechanics in N.Z, Australia and Great Britain who will get around this for a fee, if you send them your ECU. If you are considering a JapSpec engine a 1jz-GTE VVTI or a 2Jz-GTE VVTI would be a better choice for the power that you want. These engines were released before immobilizers and you only have to upgrade your turbo system and management to get your magic 400hp number...This is an excerpt from an article on tuning:- "The first step of the 1JZGTE performance tuning is simply boosting up. For that, you need to acquire a Walbro 255 lph fuel pump, downpipe, performance exhaust system 3″, and air filter.It would be enough for increasing boost pressure on the stock ECU from 10 psi (0.7 bar) to 13 psi (0.9 bar). The next what you have to do is acquiring a Blitz ECU (or another one), boostcontroller, blow-off, intercooler and increase boost pressure up to 17 psi (1.2 bar). That is a maximal boost pressure of stock turbochargers. It is enough to develop about 400 horsepower." Best of luck!!!
