Swapping engine help
 

i am not satisfied with the performance of my engine, i want the car to be at least 400 hp, is there any engine that i can swap into my Rx-8 and reach that goal. Please help me on this topic as soon as possible.

7.3 litre....
 

Put a "Hemi" in it :rolleyes:

Call the people at Aston Martin and ask to borrow one of theirs... :D

Are your parents planning on buying this engine for you?

You should consider a few things if you plan to do an engine swap.
1. Unknown drivability.
2. Future problems associated with an engine swap.
3. No warranty support from Mazda.

It is not just a simple engine swap; you will need a new tranny, fabricate new engine mounts, etc. etc. Be prepared to spend a lot of money and time in the shop.

At the end, with the potential headaches from the problems you might run into and the huge amount of money that you will need to spend, why not trade in your car for another car with 400 hp?

Find a shop that will build you a custom turbo. With a big enough turbo, sufficient fuel system and drivetrain upgrades, and proper tuning you shouldnt have a problem with making at least 400 rwhp. This will certainly be cheaper than swapping engines. A feasible engine swap would be a 3 rotor. Do a search on acosta racing, I think they did a 3 rotor swap into an rx8. But itll cost you a butt load of money. If you have the time and money I say go for the 3 rotor. You will make twice the 400hp mark if done right. Keep us posted on what you decide to do.

Wait for the PTP turbo system to come out. It will give you 300+ whp.

don't

sell the car :rolleyes:

thanks a lot macius 8, you really helped me in taking a step forward. I found the acosta racing Rx8, its sweet. Your suggestion was very useful. I appreciate your help. Thank you

I just noticed he is just 20. :D

If $ is not your concern or your parents, put a 20B in it.

You should check the "Major Horsepower Upgrades" threads, lots of info in there.

Yank the duratec v6 outta the 6, and follow the noble M12 spec's for building it up.

I'm sure adding a few hundred lbs to the nose of the 8 won't effect its handling.... :rolleyes:

check out this thread, it will have all the information you need to get more power

seriously, i have to agree with a lot of people here.

TRADE IN YOUR CAR.

It's pretty evident that you want a horsepower/torque monster to beat people at street lights. So why don't you just trade in your car and get a Dodge Charger or something? The 6.1 Liter, V8 model gets you 425 Horsepower with 420 lb/ft torque. It costs $38,095 MSRP.

and it weighs 4200lbs. get the regular model and its 0-60 time is 6sec, and with the srt-8 model you drop to the low 5s...and still lose to the evo, off the line and in the corners.

if he's going to make the jump from $30k to $38k, might as well just either get a new vette for $44k, or get a used c5 for less. then he'd actually have a chance at beating his friend...since that's apparently the only measure of a car. of course he could always go with a sti or evo also. but meh, i'm bored with this topic.

Wow, I didn't know the vette was that cheap.

I just suggested the charger since it has an impressive number he said he wanted over 400hp. :) I think it's silly too though.

drop a 26B 4 rotor in it...if your going for ultimate street machine I'd say this would just about do it. Never seen or heard of a FI 4 rotor so you could be the first :D

390 HP with a turbo has already been achieved by the guys in Puerto Rico.

stop STARTING threads about how you don't like the HP.

It is what it is.

Sell your car and save us the headache

well, now you have these recommendations, let's see you actually walk the walk and do something about it....

The force is ont strong in him!

He will go crying to his parents about it, they'll yell at him for being stupid, and he will continue to torment us with these posts.

I really don't know what to say......................

Before to "wish" 400HP RX8 you need to have the money.
That is the first question. If you have it, go for it.

As Jedi 54 said,

This is not personal but I hate when people talk about they whant more HP..................
and don't try nothing to increase the HP on their RX8 or even don't have the money.
A lot of people whants big HP in a plug and play way..............

HP=$$$$$$

For example I already spend near $14K on my car and with that money
and the cost of the car (RX8 in Puerto Rico cost $40K) I can buyed other cars to have higher HP numbers that the ones that I'm making with the RX8.
But we really don't care how much money cost, here in Puerto Rico we do it for the love and passion that we feel for the rotary cars.
