ok heres the deal, i am on the verge of buying a turbo for my 93 vtec lude and i want 450 horses. what do i need? i was thinkin about getting a 2.4 bore, skunk2 everyplace possible (already own their cam gears.) intake manifold, the list goes on. anyway, i wanna know what i need to do so that i can keep it daily driven but also draw some attention away from teh civics and integras that seem to be on every car magazine cover. ( not that those cars are bad or anything.) i want power above all else at the moment. maybe keep it sleeper for those civics who wanna test their luck. oh, im also in germany currently searching for an accord type r tranny. would the tranny help set those horses to the ground better than the prelude tranny? thanks peeps.

 

if you want 450 HP out of an H22 you wanna concentrate on the bottom end more than anything.

well i Running 7 lbs and im making 330 @ the wheels, yes you really need to work on the bottom end more .. have your car tuned out right too.. i am using the AEM EMS works like a charm... you should invest in it too

 

Resleving and forged pistons are a must.

 

also don't forget compression, depending on how much boost you plan on running try to keep the cr in the 8's, and plan on spending hours upon hours dynoing and tuning your car

 

8 is pretty low against now adays tunes and standards. I am going to be running 9.5 comp and many run (or keep it) at stock comp which is 10.1 (usdm).

 

john, i'm talkin like 8.8-9.1ish........btw how's your project coming?

 

Going along okay, Have my motor have my pistons, rods, most of my turbo parts need the motor built. Stuck on one thing however, funds....I am about 11k in debt (mostly from this project) so things are going on hold for a while. Just swaping it for now more than likely but I am getting creative thinking of things since I have all of the turbo parts more or less (need a manifold BAD). Never know whats going to happen though time will tell...

 

yeah my last project went on hold cuz well, i wrecked the car, lol, what pissed me off the most was the motor was build!, lol, and i got fucked out of it

 

get a viper.

 

Yeah that was a bum deal and why I hardly ever drive the accord any more just cant risk it.

To the person that started this thread... be sure to research the hell out of this. It can get pricey quick so decied what you want to do and find out exactly waht it takes to get there. Good luck

if you want that much power i hope you plan on spending at least 15k to do everything right the first time

 

lol **** the viper...ill give you my car if you can do this with a SOHC motor lol

 

As for 450+ horses out of a daily driver, it has been done...and my car is non-VTEC. On pump gas those values will be more difficult to reach (mean specific brake consumption, etc.), but on a race/pump mix or race fuel only, you should have no problem.

On the street I run around 8-10psi on 92 octane (dynoed at 295-328whp at those values) and the car runs flawlessly...plenty fast for any car on the street. If that isn't enough then i toss some C-16 (116octane) fuel into the tank and crank it up to 22-24psi (where i turned the rollers to 496whp on a mustang dyno).

When you are looking for this much power, you can't simply answer a question like this. You can't concentrate on one item, etc. All areas must be substantially upgraded.

For example, you will obviously need to sleeve your block, add forged pistons (low compression for turbo), new valves, retainers, cams, other head components and porting work. Then you have to worry about your turbo, and how big you want to go (when do you want it to spool, etc. and what is your "real" hp goal).
Fuel delivery & proper engine management is next on the agenda, where you will need at least 720's and 1/2inch fuel line, rail, new pumps, etc.
Drivetrain becomes more important only when the car is to see some track time. Stock transmissions can hold this much power, but an LSD is essential to lay the power down. Axles should also be upgraded, or carry some spares along with your tools on track day.

As was mentioned, research this before you get into it. Know lots about motors and know exactly what needs to be done. Always look for the weakest link or bottleneck in your system and you should do fine.

Good luck

 

450 + HP?

I dont know, a large check book and a miracle?

I mean, Todd and I are shooting for 600 crank HP, and we are having to build a serious custom engine..
But yes, the block is going to be your largest single point of failure..

 

pretty much, hope your rich

 

well, i started this topic and so i shall contribute the best of what i know rite now. im well aware of teh expense of my project, and as far as being rich... im military so i do have a very decent paycheck. i am gonna be running a turbonetics t03/04 (possible upgrade later on down the road.) with skunk2 cam shaft for better idle. then im resleeving and boring to a 2.4. i currently am running the factory 10.0:1 compression which ill be dropping to 9 held together with crower rods, and sealed maybe with total seal piston rings. dunno yet.. im getting skunk2 valves, (not sure if i should go bigger. what do you guys think?) skunk2 valve springs, skunk2 retainers, ill also have a custom intercooler made to help my numbers. i am undecided as to what computer upgrade i want though. skunk2, jet, hondata... that sort of thing. im also instaling a v-afc to change vtec engagement as well as rework my fuel/air. just for show... ill be anodizing the intercooler and all piping red. match the desired color scheme. if that isnt enough... im gonna go the nitrous express n-tercooler route. liquid co2 is fairly easy to get down here. gonna get apexi n1 catback. nology spark plug wires. once im satisfied with the way my engine runs... THEN ill sink $$$ towards teh body. engine is MOST important to me anyway. lots of time, lots of money, but lots of horses... torque, and well worth it.

 

about the viper thing... i dont do domestics. strictly a rice burner.
