Thanks for your reply
Regarding my WRX. It is actually a Jap spec '92 car so the original power was only 235bhp. I run it for a few years with 550cc injectors, 18g turbo, 3" full system from turbo back, ported headers, induction kit, fmic, apexi power fc, apexi avcr to name a few of the mods. That was dyno'd at 330bhp/305lbft
The bottom end went and the best option was to fit a 2.5l short block new from subaru. With the same mods, it must be just shy of 400bhp. I could fit a bigger turbo and get more hp as the engine should be good for 465 at the crank.
My mx5 has been turbo'd for a year with the greddy turbo kit. It is still the standard clutch in it and it mostly slips over 5k revs. I have clutch, fly and torsen diff to fit, but I've only done a few thousand miles in it since last summer when it was turbo'd. The winter hasn't been too good here and I have 7 other cars to use so parked this up for the winter.
Now with the better weather setting in I am looking to rebuild the engine as the valve stem oil seals have gone and I have a spare 1.6 engine and already bought the forged pistons etc.
I was hoping to build a 350/400hp setup here hence the original post.
I was looking at the following setup for my 1.6
Belfab Racing bottom end kit (Supertech Pistons + Pro H Beam Rods)
FM 2.5" exhaust system
Aquamist 2D Water injection + DDS3 Display
I was going to use the standard valves. Do you think this would be ok, or would I need the supertech ones too?

Making inquires on wether you can run a 3071 on a td04-h manifold is simply ludicrous. For one the 3071 is a good 30+% larger and not a mitsubishi family design bastardized to fit a niche kit. If you want an off the shelf solution for your power gaols then Flying miata or begi can take care of you quite handily. Given that you have the cash of course.
The most of us here are into making our own inferances and trying things. It is that lack of initiative to educate yourself that bothers us. Saying that a WRX u own with a 2.5 liter and turbo a good 25% bigger than your greddy can make 100 more hp than stock given more fuel etc is a rather well retarded statement.
You are dealing with a car that makes 100-120 whp on the 1.6-1.8 liter motor and trying to triple the horsepower. To equate the power gain what you did with the WRX is equivalent to us getting 150-160 whp. To equate a 350-400 whp miata your wrx would need to be pushed to 900+ whp to simulate the percentage gain you are dealing with.
