turbos? yes, fuel methods? opinions please

considering blow through carb for my soon to be twin hx35w sbc. low boost until its eagle forged bottom end, but ill do the fuel now. (its 4 bolt main 8.5 comp, plenty strong for a little boost)

so its either the carb+a1000 fuel pump and appropriate regulator+msd 6al and boost timing master or

big injectors+megasquirt+custom intake manifold+a1000(love that pump) and appropriate regulator.

as of now i have it running carb with gm hei ign. works just fine, but will be getting a digital 6 box eventually for ign and rev control.

low boost im looking for an easy 400 whp, eventually itll be more to the 750 ish range, maybe more.

would it be a terrible sin to have a 750whp twin turbo blowthrough carb s13? i hope not cause im leaning that way for simplicity. i only keep going back to fi because i could make it all fit under a stock hood (as of now its too tall and sticks out) i dont particularly like a 240 with a cowl hood..... but still.....hard decisions.

opinions? sway me one way or another!

I do not know thatt much about it. But I would be worried about a 240 holding together with 750HP

itll be 6 or more point cage, mostly seam welded, lots of reinforcement.

and they hold up just fine drifting all day long with 500+hp, farting around with 750 should be a walk in the park. i have no worries.

and if it does bend/break, ill fix it. no worries.

I think it would be easier to tune and drivability would be better with fuel injection. Never heard good things about blow through setups, but I know nothing about carbs either so I'm a little biased.

[the_momo]

tuning wise, i have a lot mor experience with fi, and a good friend of mine does and has done a lot of megasquirts, so if i do fi, ill go that route.

the only interesting thing about carbs is that the turbo v8 gn guys are seeing a LOT of power with an otherwise arcane setup.

turbo/carb/fuel pump/fuel regulator and ign box. ive seen some on stock 4blt main 350s in the 500 on a little (10lbs) boost. and idk, it seems really simple, but ill probably go fi just cause i want it to fit under my hood, and itll be more driveable.

im just gonna see what ends up happening on its own, itll have a similar outcome either way. if i come across a good deal on some major parts of either system, then ill just go that route, either way ill be happy.
