RX8 - Turbo
 

Hello everyone,
I have a bone stock RX8 6 speed manual 2004. Looking to churn out a few HP's outta this lil badboy. I'm relatively new to the Rotary world, but I do have a fair bit of knowledge about boost since I used to own a Boosted Honda.

Now I know I will be needing a Cobb Accessport for the tuning part. What I need to know is which Kit to go for ?
Greddy kit apparently runs at 5 psi (which is too low for a guy coming from 1.5 Bars of boost hehe)
Other than there there is this SFR kit which runs at 9psi. I'm looking to keep the internals stock since it's a daily driver. Looking to get atleast 400 WHP.

Any advices will be greatly appreciated.

There is a pretty good chance you will not get to 400 without a very pricey build. The Renesissy is not very tolerant of boost stock. I'm pretty sure most of the guys around here getting over 300 have been through a few rebuilds. I'm also sure I won't be the last to tell you about it.

I say you sell the car and buy Chris's RX8 ... already boosted an well maintained. Boom done

rotary is a different world my friend. Boost or no boost

You should try to keep it running for a while with no boost. Read around.

electric supercharger and power chip from ebay. done.

I only got 375 with the ebay mods. That last 25 is very tough. Maybe I need a bigger spoiler.

but he wantz turboz fuz
400hp DD...weksos

20b i think fuz said bse50 makes them in his garage. send him a pm

I have a couple extra 4-rotors just lying around. You can have one or two really cheap if you want.

400whp on a daily driver? Not happening.

Ooooooo

In all seriousness, getting 400whp is not going to happen. Good day sir.

I love how he talks in terms of "PSI" when referring to how much power a setup will make...

I have a set of custom SQUARE ROTORS for sale bro.

25% power increase (4 faces vs 3) and can handle up to 3bar of boost

pm me, would be sick with your rebuild

lol, nice plug

paimon should get some commission

You guys are mean

Shady wins again

He's unstoppable

LOL winning

:)

:bowdown:

It is, after all, a game, Dr. Falken?

Why aim so low ? 400 is sooooo last year .

i don't think he searched on thing about the renesis motor or boosting them before he made this thread. there is a section on this forum dedicated to major horsepower upgrades..

OP, you have experience with boosted honda's

so why don't you install VTEC on your 8?

would be hellasick YO!!!!

Better smarten up your act shady - you have competition !

Hmm- I beileve the general consensus is the stock motor won't be able to go above 300 whp on boost, am I right ? Well then I'll need some advice on building it then. Just a minor build, need no more than 400whp.
Some guy mentioned about PSI, I understand that 10 PSI of a t3 t4 is a lot less power compared to 10 PSI of a GT35 :) Which is why I mentioned the KIT (they have specific turbos)

Whats the maximum the stock block could handle, just btw ?

^ once again


SEARCH

I believe the general consensus is that you have no idea how to search for the answers you seek. the answers are in this forum, but you just want to be spoon fed the answers.

hell im not even blown and ive done easily 20hours of reading forum members build threads and other relevant info

i suggest you do the same

if you want a reliable 400whp, you shoulda bought something else.

Whoa, lots of hate in here :-).

400whp build have been done but they were either project cars or shop cars which don't live life as a street car.

There are numerous challenges with such a build. First, you're going to need a healthy motor which will mean you're going to want to rebuild your current engine. A lower compression motor won't make high power like what you're looking for. There are a lot of rebuild threads with a wide variety of builds. Some people do a factory build, and others waste tons of money on stuff that doesn't benefit them except pad their mod list.

Second, heat is going to be a problem. The RENESIS does suffer from heating issues and will require a radiator upgrade at the minimum with probably additional cooling being a requirement. There are lots of threads dealing with this problem.

Turbo sizing is going to be an issue because kits like the GReddy are low mount kits and are restricted by available real estate. You can't shove anything massive in there so you're looking at a top mount style kit. They have their pluses and minuses and there are quite a few threads about those kits and their reviews regarding vendors.

You'll have to obviously deal with tuning, ignition, exhaust etc. and there are tons of threads on those subjects as well.

There is no single off the shelf 400whp kit. You'll have to piece something together that has characteristics which the car requires.

Lots of self proclaimed "experts" around here, so do a fair amount of reading before taking advice.

400hp renesis I'll believe it when I see it!

oops - looks like I over-estimated this motor. I guess my integra was better off which made 403WHP on a stock block.
I guess i'll just stick to stock for now and maybe sell this and get an FD next year.

I'd still love to know the power numbers on those stock rx8's with Greddy kits.

Oh look another one!!!!!!!

Just sell your RX8 now

all your answers on the greddy kit are in this forum

SEARCH!!!!!!!!!!!!!!!!!!!!!!!

better luck next time buddy

and no, you did not make 400hp out of a honda motor on stock internals, your e stats have no place here

:rofl:

fuuuuuuuuuuuuuuuuuuuuu

All he needs are some Skunk2 cams and some spoon wheels.

BTW, I heard the turbo kit coming out next month by Se-Arch is the nuts.

403 on a 1.8L integra? You are trying to sell us that the stock internals were good for over 20psi? Good luck with your FD, just a shame you will ruin ones of those too i'm sure

I'm willing to bet it was some sort of setup with a high and low boost setting on a giant T3/T4 that spooled slow as hell. The 8 isn't meant to be a burnout machine.

No offense to you all but you guys really need to stop being under that 'rotor' stone and look around you. Go visit Honda-Tech and see the dyno charts there. Leave B18 (1.8L DOHC HONDA MOTOR), the 1.6L B16 on stock internals does 370WHP with 1 bar of GT35.

You probably shouldn't be upset at anyone but yourself that you failed to research before making a car purchase....

The problems with making power with the Renesis are well documented, meaning the challenges you will have to specifically address are well documented.

But its fwd and doesnt drive well... I'll race any 350whp civic on a road course for pinkeye.

I live my life a hairpin at a time and in those .88g's I am free.

straight up answer from Shady . :yelrotflm

he read it on a forum so it must be true ...

out of most of the wannabe trollers on this site, your trolling sucks.

Hey why don't you bring up the powerband jokes next?

I just read through all of your posts... Why are you so angry all the time?

If you drove an automatic RX-8 you would be angry and bumping useless threads too.

The internet was made for anonymous, angry people that can't locate the SHIFT key. 3 pedals all day.
