Let me start off by tell you what im lookin to get out of my car.
I really want to get between 300-400 HP with what ever upgrades it takes. I just need to know what they are.I'll probably add NOS later but i want this power out of just the engine.Is this possible? or will i need to upgrade to a different engine?
here are a few of my questions
1.Is there a way to make this a 6-speed like if i used a acura TL clutch?
2.will a turbo or supercharger ruin my engine in 8-12 months?
3.Whats the best way to go? turbo/supercharger? what brand?
4.If i change my pistonsand all that will it make that much difference in HP?
5.Can you list some upgrades such as air intake,exhaust,inter-cooler,etc.

Thanks for taking the time to read this and giving your advice.

 

Which engine do you have? h22? h23? v-tec? 300-400 at the crank or wheels? Are you going to use an LSD? Is this your daily driver? How much are you looking to spend?

1. I would have to say no on that one, you would need the entire transmission and all that and I think it would be a pain in the ***. I don't know what 6-speeds bolt up, etc. And most likely you'll need a new one for this kind of power.
2. If built right it shouldn't ruin your engine at all, which comes to my answer to 4
3. Personal preference, I like supercharging but I grew up working on Mustangs and Camaros, turbocharching would do just as much as a supercharger.
4. If you're going to use forced induction, you will definitely need to change your pistons, head, cams, injectors, fuel system, valves, rods, pulleys etc especially if you want to make 300-400 HP. The head and pistons will correct your compression for the forced induction. If you don't...well your engine won't last long or put out the power.
5. Like I said I worked on Mustangs and stuff so I don't know a lot about modifying a Prelude this way as to what are the best parts. I've heard good things about Greddy and used one of their turbos on a Honda F4i motor. Intake, exhaust and intercooler could depend on which turbo/supercharger you use.

All I have to say is GOOD LUCK getting that much power out of a Prelude engine.

 

That power coming from a prelude engine is more than possible.

For instance, check this thread out:
https://honda-tech.com/zerothread?id=1009944

Built correctly, prelude engines (h22 or h23) could throw out loads of power. If you are looking to get 300-400 horses, then yes, building the bottom end of your engine (the block) is highly recommended... otherwise you're looking at replacing a lot of ****.

This is a pretty big thread on Prelude turbos (official turbo thread).
https://honda-tech.com/zerothread?id=316373

 

1. You don't need 6 gears, and it is highly doubtful without major cash flow that you're gonna get it to work. You want 6 gears, try an rsx not a lude.
2. Yes a turbo or supercharger in a hands of a dumbass will definitely ruin your engine in 8-12 months.
3. Turbo for big power, get a big turbo.
4. "If i change my pistonsand all that " First figure out what "all that" is going to be. Yes it will allow you to boost higher, therefor making a huge difference in HP.
5. Turbo, wastegate, injectors, fuel pump, turbo manifold, oil lines, engine management, dyno tuning...and the list goes on and on

 

If done right a FI - (Forced Induction Ie: Supercharger or Turbo) will last longer than 8 months. But just for your information, with 300-400 hp on a prelude you WILL be spending quite a bit of money, time, and repairs in the future.

Something that you mod heavily will have reliability issues over your stock vehicle.

Intake and exhaust is the least of your worrys for 300+hp...

I wouldnt bother with the 6 speed, the 5 speed will more than enough do 150mph, and thats as fast as you should ever need to go.

Your almost going to have to go Turbo, definatly going to need to do a major engine overhaul, sleeves, pistons, pretty much the entire bottom end. And get some decent FI head work done.

build a custom turbo kit, theres alot of people on this site that have done beautifull work with their vehicles, and are producing more than 400 out of preludes.

But as an estimate, I think anything over 300'sh hp is going to be around 10,000 or more.

So if your not prepared to pay that much... Id suggest you drastically lower your HP aspirations.

the key factors for that horsepower are, Engine management system, Turbo setup, Exhaust, Head work, Bottom end build, Transmission upgrades, incld differential, Axles, and definatly Brake upgrades.

With 300+hp in a prelude id also recommend some type of rollcage. Above is no were near all the items you need, but the most important off the top of my head.

Before you buy any parts for your car, Id suggest learning everything and anything you can about these cars.. and what your getting yourself into. From the sound of it, I dont think you understand the full picture of what your asking. It isnt easy at all, and will take an extreme amount of planning and funding.

Just whatever you do.. have it Dyno Tuned by a professional that has a good record. Tuning is the most important thing you can do to make your setup last.

300hp aint playing no more.

 

You can't make a 6 speed lude (unless your filthy rich and bored). Even if you did its not a clutch that makes it a 5 or 6 speed its the entire transmission.

If you want that type of power you need to have your engine rebuilt, pistons, rods, ported, the works. And thats not to mention getting 400hp to the ground.As well as a big pocket book or the willingsness to get into huge debt. Or just be very, very patient and save over a long time.

A stock engine can be blown up in the hands of the wrong driver. A turbo/sc car can last years if taken good care of.

http://www.turbo-kits.com has a list of parts for different turbo kits.

Ill post a link to an awesome place to learn more about the components of a turbo kit. I would highly suggest learning as much as you can before you start this project. If you can I would suggest eventually getting a 2nd car too.

yeah, first off read the turbo thread, tons of info covering all the basics and more.

some of the keys to a reliable turbo setup is the bottom end build (sleeves, pistons, rods) and the tuning. going turbo is a huge commitment of both time and money, you'll find when you research all of this just how much time you spend trying to figure out what you want to do. I think 300 whp shouldn't be too tough with the right setup.

the parts list for a turbo upgrade is long. very very long. it starts with a kit or individually sourced parts like the turbo, manifold, etc etc. then you need forged pistons. to run forged pistons you need to send your block out to get sleeved. to make sure you don't throw a rod you should get forged aftermarket rods. not sure what the turbo guys have been doing about the crankshafts. you prob need/want cams/camgears, some headwork, 3" exhaust from collector to tip, engine management, new clutch, aftermarket axles, limited slip differential, and the hits keep comin.

so, good luck, do your research, and enjoy your high hp monster!

 

i agree with what these people are saying. make sure your willing to have a lot of downtime for your car and its going to be costing u big bucks.

as for the crankshaft, most people have been leaving it stock.

also, good luck getting your car smogged.

 

If you are going to go FI, do it the right way the first time or expect to waste A LOT of money, have A LOT of headaches, and A LOT of wasted parts.

I am not a fan of turboed Honda motors. There is a reason why it costs so much to go prep the engine for FI. Not worth it in my opinion.

 

First of all by the sounds of it your are pretty inexperienced in both technical and mechanical aspects of the car. The only way to make that power is with forced induction aka turbo or supercharger. If you want 300-400 hp go turbo. Get a good shop to put it on. That shops also gonna need to take out the engine and rebuild it for a turbo. Then you'll need axles, clutch, lsd, etc. It is a lot of work. Then a management system. It goes on and on. Youre gonna need a whole lot of cash to do this. To have a shop do it, expect a bill near $10,000. So you might wanna reconsider your options. Do a full naturally aspirated build but keep it mild. You can easily throw down 240 hp at the wheels. You'll save alot of money over the turbo, and your engine will last longer.
