I'm going to try to make a meaningful reply here.
To the OP: if you genuinely want 400 RWHP, and this is for a street application, you're going to need a Chevrolet LS7 engine, a T56 transmission, and the differential and conversion kit of your choice. The Belfab parts and your spare engine, along with your current engine, transmission, diff and axles can be sold to partially offset the cost of this conversion.

A V8 is not needed, but I'd say that only the ECU will survive the cut for replacement parts.
FM 2l stroker, low comp pistons Disco potato, WI and pretty much everything will get you close.

ibtl!
seriously.. go find someone that will give you a run in a boosted miata... at 200 hp, they are contenders with lightly modded mustangs, camaros, etc.... 250 hp is almost scary.
if you REALLY wanna make 300, rebuild with better rods/pistons, get it up to 250 hp, tune it WELL, add nitrous...
or just put a 150 shot on your 150hp miata, and blow it to bits... we dont care.

400HP has been done on a BP motor, the purple minimonster. It was a stock block at one point to boot. Then again, that car was not exactly a 'street' car.
Big turbo, NOS, engine management and fueling, RX7 drivetrain hardware from the tranny back. And a lot of time and money to fix 'sploded parts. These are the requirements to reach that kind of power in a nutshell.

Jees a lot of you get uptight from me asking a simple question.
I did search and have been reading the forum for a while.
I currently run the greddy unit at 15psi, but the valve stem oil seals are gone, hence why I have bought the forged pistons as rebuilding a spare engine to go in.
My subaru is running 550cc injectors and is 400bhp so I though those, the ecu, fmic etc would run that power. The only thing I knew wouldn't would be the greddy turbo.
Looking through some more posts this afternoon there is quite a few people running over 350hp on their cars with not much more than me bar a different turbo.
I didn't expect the abuse and childish comments. A simple answer would have been suffice. If you didn't want to answer, then why bother posting?

To the OP, from your language and choice of some parts, I think you're based somewhere across the pond - UK is my guess.
Not that it matters a lot, but your availability of parts might be different from what we recommend over here.
Like Joe has said before, the thing that makes most sense at that power level is an LSx series engine.
For a 4-cylinder, I would say a K20 series or F20/22 boosted engine is the best choice. Lots of people making 350 whp with the stock bottom end with zero reliability issues.

Hi
Yes I am from the UK. I know some of the parts wont be available here, but I can order them from outside the UK. I know the exchange rate isn't too good at the moment, but that doesn't matter.
I've seen a post with this spec of engine. The guy says he will reach 400rwhp
Stock head no work
Stock intake manifold
Stock block
KnockSenseMS
GT3076R (With t25 flange)
18x12x3 ebay intercooler
ETD Dual Feed Rail
1000cc injectors (low impedance)
Walbro 255
3" straight pipe exhaust
Water injection (probably devil's own)
Godspeed radiator (if and when i need it)
01 6 speed
kaaz LSD or ford 7.5" rear (havent decided yet)
Energy suspension bushings
Chromolly cage
Driveshaft loop
Scattershield
Where can I get the GT3076R (With t25 flange) & ETD Dual Feed Rail from?
What manifold will I need to use the GT3076R as I don't think it will match up with the greddy one?
cheers

Nobody is hitting 400whp with a stock motor, end of story.
I think there's someone on here who's going to try it, but he's expecting to blow up his block anyway.
edit: Good thing your buddy has that Chromoly cage and Energy bushings, I think that's probably what we're missing over here
