i have just recently bought a 89 fc3s which is pretty much standard aside from 3in exaust, pod and timer. i am planning to make the following mods;

RTK7 v1.8, 4x720cc injectors, walbro fuel pump,BNR stage III turbo upgrade, FMIC, Electronic boost controller and BOV.

Just wondering if it is possible to make anywhere near 300 rwhp with the planned mods and would it be possible at 12psi? how about 14 psi?

I made just under 350WHP with almost the same setup. This was at 14-15lbs of boost.

stage 3 I believe at 15psion are capable of around 340+ rwhp. The stage 4 made 370rwhp at 15 psi. You can always email bnr and ask about the setups they used.

Big problem: they don't make Rtek 1.8's for the 89 cars, not yet anyway. They are only testing it. So you'll have to wait.

i had a similar setup, and had 365whp/325tq.

shouldnt be a problem.

how are you adding more fuel if you can't adjust your fuel map without going rtek 2.1

these figures that you guys are talking about im guessing they were ported engines? mine is unported and i dont realy plan on opening it up unless i destroy it, this is going to be a budget build, hopefully anyway.

my engine was un ported, and i was lazy and didnt run a high octane mix every time. kinda ended up blowing cause of that.. or was it from the piggyback?

either way, i have more than enough fuel now, and a haltech instead of piggybacks now.
