J-spec MOTOR = 305hp?
I've been educating myself about the FD and was aware that the JDM turbos were an upgrade from stock by quite a few horsies, but have never read about the JDM engines themselves being different. Well, this one add claims the J-spec motor he just installed produces 305 hp and that's thrown me off. Is this guy misinformed or am i? thanks in advance -Clint

J/K I did have a 96 JSpec motor and you know that they are pretty much the same. A block is a block. The only good thing about JSpec motors is that you can get them pretty cheap with low miles on them...I didn't have time to rebuild so I bought and dropped a motor that was brought in for me.
It ran great especially on the T04S till the day my car was stolen.

Hi
I have 99 FD.
No modification on the motor.
Just stock replacing K&N air filter and KSP titanium exhaust.
And normal boost and RE-A ECU.
Then , 310 HP by RE-A dyno.
Thanks

Actually part of the power increase was that they were able to use a LARGER downpipe. Technically, the outer diameter is the same, but the wall thickness is thinner, so the inside diameter is a touch larger.
Even if they had to cut power back down, exhaust restriction would be the wrong way to go. Remember, it's a TURBO car. No sense in adding exhaust restriction (which hurts response and engine longevity) to limit power when you could just as easily lower the boost level a hair - lower boost means lower intake temps, longer engine and turbo life, and faster spoolup to max boost (simply because max boost is lower!).

I was on the plane to NZ, talking with a guy who imports Aussie GTR's. He said that it's not uncommon for a healthy stock GTR to put down 300 hp. Unless he was just blowing smoke... Just what I heard, though.

My question here was I know for a fact that the current stock FD does not put down over 300, so how could this guy be claiming 305? It sounds like a claim, without dyno backing, and he'd have to get that number from somewhere ... which brings me back to my point -- it couldn't possibly be published anywhere for the two reasons I mentioned before.

The 99-spec FDs supposedly pull high 12s with "280" hp, so my guess is that it's actually underrated somewhat.
