and dont forget one of those front facing intake manifolds and use 3 inch intercooler piping it will be easier to work with that turbo / front mount / throttle body.

Why 1000 hp? Why not 2000?

1000 horsepower is a bit extreme if you plan on driving it any where but the track. You should really focus on a streetable 500-600 rwhp. If you're building a dyno queen or track car then I guess you can build it as high horsepowere'd as you'd like.

There are a few guys on here running around 700-850 rwhp on a 7m. You may want to check out their thread. Good luck.

For the IC piping, 3" from turbo to IC, 4" from IC to tb, ditch the 75mm tb for a 90mm tb. Why are you going .040 over? Bore as little as possible to keep meat on the block. The head will need extensive modifications for those cams. You're gonna need some sort of turbo header, and a Front facing style manifold, and a wicked fuel system.....shoudl i keep going??

Not trying to be a dick, but you got alot more to think about, and i'm speaking from experience....

I'm not implying you don't....Just take whatever # you have in your head that you think its going to cost to have a reliable 1000whp 7m. Then double it, and you might be in the ballpark of what its going to cost to build one, assuming you do everything yourself. Its really not all its cracked up to be....i kinda regret doing a bunch of expensive custom shit to eventually make over 1200hp on a 7m, I'd much rather have kept my 600hp one together and used this $$ for a house or something....

You'll need at least 1200cc injectors, 1600 would be erring to the safe side, but may not be a bad idea....

3 walbros is a bad idea IMO, you shoudl go with a Weldon, with its controller, along with a sumped tank, -10 dual feed fuel rail, weldon reg, etc....

i dont want to sound like an asshole... BUT if you have to ask for a parts list for it... then youre better off just dropping it off at a shop and saying build me a 1k hp engine and paying them money when they ask for it.

what about ceramic coating on top of the pistons and valves , balancing the rotating mass ,, oil pressure,, tilton cluch or something strong,, you will go with underbuckets shins or one piece lifter like echo lifter ,, ???????????????:aigo::aigo::aigo:

I'd be somewhat worried about the crank/flywheel bolts at 1000 BHP, let alone 1000 rwhp. I'd be expecting that there'll be crank problems. Add at least a forged crank to the list, possibly custom (JZ flywheel?)

so should i look more foward to a streetable 600-750 maybe? still as fun? but more reliable?
500whp is what i'm shooting for, i did some looking around about a week before i decided what to do with mine. 500ish was in my price range of $4500, that didn't include a tranny rebuild though, or an ffim. so tack on another $1k already lol

i would love to build a monster car, but i am also a realist and would rather have things done correctly the first time.

7m has a crappy flowing head.. fix that first...

get oversized valves, get a nice set of cams, and you will have to do something about intake, as well.

port and polish the head... alot.

Stock crank will hold it, Mibrum hasn't twisted a crank since he fixed the fuel wash problems, and he's well over 1000.

Go to http://7Mpower.com and have a look at the writeup there by Will Neely.

You will absolutely need new flywheel bolts, Duane snapped his at ~800. You'll need a better harmonic balancer on the front, too, talk to ATI about getting one custom made.

I suspect you'll need new bolts on the driveshaft to rear diff interface, too.

There's a crapload of other stuff you'll end up needing - as suggested earlier, have a look at some of the already existing high horsepower builds, that will give you an idea of where to start. Remember you're shooting for even higher numbers, so everything will have to be one step up.

Oh, and one last thing - be prepared for a lot of stuff to break.

You'll need more than 1 ssqv, I'd just go with a Tial. 3" intercooler piping, 4" coldside. 4" exhaust, and a bigger TB, and some amazing tuning.

i once thought that making a big hp and still reliable 7m won't be that difficult and expensive , but i only can say, forget it, it will take a load of research, a really good engineshop that really know what they are doing and really really deep pockets.
I really am a 7m fanatic, but if i had to do it over i would go with a 2jz (and i'm not even half way with my 7m project, and my powergoals are half of your 1000hp plans).

A "genuine" 500+rwhp 7M that can be daily driven at 500rwhp without changing things for the dyno is a handful and great fun.

Reliable 1000rwhp driver.... as much as I'd like to see it happen it's a HUGE ask.

pulling 1000rwhp with a 7m is possible, but reliable now way :nono:.

powerglide 2spd auto and about a 5k stall, that ruined the street fun part. Anyone know if the r154 can take the abuse??? High HP 1JZ/R154 guys dont count, not enough torque to break it... :sarcasm:

It can't. Will Neely has been quoted as saying that he could peel the teeth off the gears inside the R154 like pulling corn off a cob at will, and he was a lot lower than 1k.

You might be able to *make* it hold.
