How to get 350hp on a 290hp sc400 vvti?
 

Is this achievable? I'm looking at a custom exhaust, bfi mod, imf headers, and altogether fine tuned via safc at a dyno shop. I'm really shooting for 400hp with the addition of nitrous. I figured a 50 shot on a v8 can be ran all day than compared to a 75 shot. A small 400hp beast should do pretty well for a Sc.

350 bhp w/o nos would be awesome. Pair it up with a manual gearbox and LSD and call it a day

Initially I was thinking 325hp na bpu and to add a 75 shot of nitrous. Then I hear the rods off the 98 vvti 1uz can't support too much nitrous, so I'm hoping for 350hp na bpu and to add a 50shot on top for a total of 400hp.

exhaust, tune it and manual kit. and then pray.

So not very likely huh? Hey redp did you run your converted manual on the dyno?

exhuast headers safcII what about 2uz cams

No, but he says he has a friend with the same powertrain and he dynoed it at like 230+- RWHP.

two words...Nitrous Express

If used correctly it can be reliable...I would know, I ran a 125 shot on my G35 for almost 3 years...

Yeah I have a graph somewhere overlapping them in my filing system.

Mine - 211whp/230tq
His - 230whp/249tq


Both are 92 SC400 Engines.

The only difference is he is running a 4.1x rear end, and I am at a 3.92
We both have exhaust, stock ecu... We dyno'd at the same time.

^^^thats gotta be fun, having a V8 with a 5spd....i read somewhere on here i believe where people were sayin we should not underestimate the 1uz, they can hold power, or does that only refer to the non vvti ones

From what I understand, yes thats true. The vvt-i's arent as strong.

..but man, oh how I would love 350 hp :thumbup: I've read all the threads about the headers and exhaust. Just doesnt seem to be any easy (or cheap) way of doing it. Seeme like any of the options available are kind of a PITA :sad:

What side effects does nos have on engine internals?

SRT Intake/ Exhaust will get you pretty close.

has anybody tried the rush import headers/long tube extractors

where can i buy them... i've searched for a website online and can't find anything... except soarerworld...
