what changes to make to TURBO my rx8?!!
 

I was first considering swapping my motor out to a 20b but then i realized how much it would be. so now im thinking about boosting my 2004 rx8.
I'm kind of new with turboing a car so i would like to know what exactly i need to change in my stock engine in order for the engine to handle the turbo and not blow.(seals,rotors,etc.)
thanks!!:dunno:

SEARCH...READ...AND THEN ASK specific questions :)

You are gonna have to buy some Titanium Valve springs if you want your engine to handle the boost from the turbo. Other than that, the Turbo Kit should bolt right on with no worries. You can easily do it yourself.

why is there so much stupid on here today?!?

^:dunno: young kids that think everything is slap-on-and-go. I've pointed it out to a couple and other members that you never see such stupidity on the RX7 club. :yesnod:

Man, you guys really need to chill out with this stuff. 813dannykoofey, you really should research the topic, but you will still have questions. I've been reading and researching for almost a year trying to learn about boosting and supercharging, learning to read dyno charts, figuring out which FI systems are good quality and give most power for money, even thought about twin charging!

But while these forums do have some good info, don't expect too much help. Most of the threads you'll come across start out as what your looking for but end up just being arguments between forum members or they'll end up with no conclusion whatsoever. For example, you asked a legitimate question, and now they peg you as a kid who thinks he knows everything. Good luck.

Like I said...Search..Read and ask specific questions.............

There wasn't a "legitimate" question in the minds of many of us..............

Most of the threads on this board concerning FI builds are all about someone having it done. "Turbo Ultimate setup", "My turbo install" etc. They just show someone having it put it. Maybe I'm looking in the wrong spots or something, but I've basically been having to teach my self everything. Even threads that actually pertain to what I'm looking for are usually just argument or threads like this bashing the thread starter (not saying you did, the other guy did).

I also didn't say he shouldn't reasearch. But even after my research (which is still on going), I'm still unsure of many things.

@ dannobre^exactly. He didnt mention anywhere in his post what kind of turbo kit he was planning on putting on his car. Depending on the turbo kit he plans to put on his car will give us at least little info to whether a base or upgraded rebuild is reccommended. Its not that we are trying to be dicks, but were aren't genies in a lamp either.

Its like asking us how high he can climb up a ladder when we dont even know what ladder he is using.


@Strifex- Overboosted Overlords is a good thread. It includes almost everyone who is boosted on here complete builds. He should read through all of those and read about the fixes with some turbo kits and the trouble shoooting they had to go through.

There are 40+ RX8s with Prochargers, Superchargers, Turbo Kits, Custom Turbo builds, Nitrous Kits, etc. He should start there. All thanks to KANE, and heres the LINK....https://www.rx8club.com/showthread.p...sted+overlords It only took me about 10 seconds to find it. :spank: Just because someones turbo build went peferct the first time doesnt mean yours is. Almost everyone I know that has done FI of some sort has had to do a rebuild.

You dont need to modify anything if you are going to stay around 300rwhp(more than the stock greddy kit can reach). If you are going to exceed 325rwhp you'll need to upgrade injectors and most upgrade to the walbro fuel pump. Other than that the engine itself takes boost just fine.

@nycgps wow, you sure are helpful.

@ZumnRx8 Thank for that link. I don't know how in all the time I've researching I've missed that thread. It still seems to be mostly about "Hey, look at my build," but its much more helpful than "search"

wow, like u contribute anything?

nothing.

I can't answer anything when the question was too general ? OMG I WANT TO GO FAST ? wow. ok, strap a rocket on urself and be done with it ?

ok? might as well stop acting like u're such a nice guy ?

wait till you actually HELPED SOMEONE/SOMETHING, how about that ?

I never said I did contribute anything. I'm pretty sure I was actually looking for info just like the first guy. I only pointed out how even if you search, most of the threads look just like this one, with a bunch of useless posts telling the person to search or getting in a debate with another member, and never getting any info. ZumnRx8 and Mawnee actually provided some info. So, threads done.

And did you suggest that I stop being a nice guy? Why? So I can contribute to the nonsense. Nah, I'm alright. Thanks again ZumnRx8 and Mawnee.

For some reason I just search using this site's search engine and guess whattttt, I found all the post you and the op needs.

*sigh*

if u don't search/can't search for shit. its ok. just don't act like you did/try harder.

^^Both of you girlies shut the fuck up and stop getting free posts. :).
@strifex you didnt try searching hard enough and the OP obviously cant find the search button.
@NycGPS- why are you even wasting your time arguing? /thread.

well...at least he asked.

my opinion..

in my opinion you should:

1. Get a compression test.. from where?? YOUR LOCAL MAZDA DEALER. I would like to say 7.7 or higher is ok to go ahead with your turbo project. Maybe im off, correct me if im wrong.

2. decide you budget. how much are you willing to spend by dollar amount

3. what are your power goals?. then refer back to STEP 2 to see if you're being realistic.

4. Who will do the install?

5. Who will tune it?

6... lastly, who will rebuild your engine after you blow it up? haha

My apologies. I never intended for a debate to start. Anyway, thanks for the info. I'm still searching and learning about all this stuff.

thankyou fellas for helping me and giving me advice on how to ask for questions on this forum. but im sorry i wasn't specific enough about what i was asking.
okay here's my questions.
i would like to buy a t3/t4 kit just to get a little more power like 300hp around there . will my stock engine hold up the force of the turbo for it as a DD? and what brand of turbo would you recommend? or can i just buy a $500 one on ebay and call it a day? lol

^you better do some more research... this isnt a HONDA.

yea i know i was reading the link that you gave me on the Overboosted Overlords and im starting to understand more and more on the FI. There is so much more than just bolting the kit on. cooling system, oil , etc.

I think all ladders go up, but we could be talking step ladders or folded ladders with extensions, or just a normal run of the mill 5 foot ladder. Either way, don't stand on the top rung. :nono:

this thread gave me a good laugh. not the OP
but the girls fighting in it.


"U gUys MAD?, WHY U MAD BRO?"

Dont taze me bro!

I'm just sayin' .... :eyetwitch

Damnnnnn ! Thank you bro, you just ruinnnneeedDDDd my plan !

Argh !

Instigating doesn't help anything. Plus, I wasn't fighting. Just disappointed in the "help" around here. It's been settled. Nothing to see here.

i agree with you StrifeX.
i ask a simple question looking for some decent answers from people that are more experienced than me and i get disrespect. its all good though imma keep searching

nice :)

everyone stop the bitching.

dude--- sorry you are not getting an answer to your questions. I remember when I 1st started out.
The forum has so many dang pages of info it is not easy to search.
Now I dont know much about turbocharging, but i do know a little about supercharging this car.
FI is FI but there are a lot of "details"
Heres some starting advice that may be helpful
1- get your engine in good shape. Have your engine coolant temps well under control--probably need to install gauges or get an ob II reader. You may need to add some mods to get your temps right--this is an easy search.
2- new ignition parts---plugs, wires, and coils
3- make sure your fuel pump is good--again easy to search about this.
4- research a lot about what system/components you want to use. Install it
5-get a real good tune!!
6- run a water meth system with it
that is the "basics"---sounds simple.
It kinda is--just a good bit of work and money.
You dont have to have a rebuild, special seals or anything like that.
As long as your engine has good compression --you are ok.
Now like what was said--if you start going over 300 rwhp then more stuff needs to be done.
Hope this helps a little
Olddragger

thanks alot olddragger! about the compression.these motors come with high compression and i need low compression.. what can i do to make it low compression.?i should search right?? haha

no-- you dont need low compression for 300 rwhp.
OD

you don't want low compression at all

Low compression = Needs new motor. You dont want that.

In fact, you want 'good compression'. Its advisable to get a compression test to make sure your current engine is ready for the project...

Also,

Make sure you have a solid $4,000-$5,000 set aside that you can spend at any given moment incase you need a rebuild. Not saying that YOU WILL need to use it, but as many would agree, this isnt the type of project you should take on if you're not financially ready incase something goes wrong. Remember, you're going from 180whp to 280whp, there's a chance things can go wrong.

This is the exact reason I havent boosted yet, Ive had enough money for the kit and install on multiple occasions over the past couple years, but didnt have enough set aside for tuning or a new engine if something happened, so Ive held off.

he is speaking of lowering the standard compression ratio of the engine so more boost can be tolerated and therefore increasing the flow which allows more power to be made.

Simple turbo
 

Wanted to know if I put a simple t3/t4 turbo , would I need to modify anything to the engine? Not really wanted to change the engine or anything just something simple.. Help new with rotary engines
