Found this over the weekend at a car show i went to, guy said he was running the \'Greddy turbo kit\' and it was pushing around 300 bhp, apparently it had a custom turbine. He said he\'d spent quite a bit of cash on it, sorry i don\'t know much more about it, i know it looked very nice it was erm "on its arse" on D2 coilovers. One of the nicest RX-8\'s i\'ve seen and it was VERY loud and pretty fast as well :mmmm

Just though, it might interest a few of you.
So its making just about stock turbo power that an FC does with a few bolt ons? I do like how the radiator is getting blocked by the battery and the air filter is sucking in hot air from what little air gets though behind the rad lol
that engine bays actually been reconfigured with the battery moved from where the air filter is located in the picture.
the Stock engine bays actually a little more crowded.
wonder how he gets on with cooling
Oh yeah Mitch I\'m in no way saying it\'s better than my stock FC ;)
And I\'m certainly not saying I\'d rather have that over my FC, what I am saying is it was the fastest (and loudest) RX-8 I\'ve seen to date. I feel anyone who has put hard earned cash into a rotary engined car is deserved of some aknowledgment, thought perhaps these RX8 boys would respect it a bit more than us :p
I\'d choose my FC any day!
that rx8 may only just have the power of a stock FC guys but it probably has all of them in it, wheres as your FC\'s have lost a lot of the ponies, oh and the rx8 chassis will walk all over your FC\'s in most situations as your cars is not so far off being as old as my RX4!!
Now dont think im an rx8 fan because im not, i find it hard to like them apart from use on a track, but they are a superior car in most cases, except for maybe looks?

You missed the biggest restriction of air flow into that engine bay though mitch, the huge number plate covering the passage into the bay:yes
If you like this you might like the one in this you tube link, wow, I even liked the color for some reason,

I bet you £50 it\'s yellow
Yep I was right, now where\'s my money?

wheres the biggest laff out loud smiley? :rollin<<< this will have to do
oh and the mouth of the 8 is closed off stock on purpose! the number plate makes no difference! why? the cold air flowing through the bay was causing problems with how the oil cooled in the rotary ... something they realised when testing the 8 and have obviously conveniantly forgotten to tell you guys :evillaugh food for thought :2Rolleyes
also the radiator is mounted on an angle rather than upright in the 8! and its \'scoop\' is the bottom vent below the plate between the oil coolers!
i can tell you this 2! 300 bhp is pretty pethetic on a turbod 8 - theres a chap on the oc just sold his running 450 bhp with the boost turned up to around 1.2 or 1.4 bar (i think) on stock ports!!!
any supercharger will give you between 320 and 360 bhp with stock ports - modding the 8\'s is only just beginning on large scale really - combined with all the moddern tech, chassis, suspension set up etc etc i think some of you older hardcore rotary chappies are gonna have to admit to moving over on the track when and is scraping paint off your bumpers :p
in the meen time tho im still looking for a FD to rebuild so if anyone heres owt ...:Laugh
Guess you missed my sarcasm in that post then?
The FD radiator is mounted at an angle too on a standard FD
sorry buddy i wrote that smiling :yesno offence ment at all - its difficult to do the joking around thing in writing! by the way your just around th corner from me :2eeki live in liversedge, next to heckmondwike :WaveBye went to collagfe in huds and its definatly my favorite stomping ground :Thumbsup!
Wheres the IC located?
Ha ye I know trying to do jokes is hard through typing. You can put the same effect into it. I live in dalton in Huddersfield so were not far apart at all. Very cool.
Quote from: m1tch;786685Wheres the IC located?
If you zoom in onto the frst picture I think you can just see it above the lower lip?
is IC short for intercooler? - if it is you can just see it through the bottom vent - basically infront of the radiator! :wiggle
you know im sure the turbo is right underneath that intake filter :3Confused
hahahaha oh yeeee that IS the turbo i get it :Hammer
On the greddy kit, the Intercooler is a straightforward front mount, it\'s directly below the numberplate. You can see it in the first photo.
That kit will make quite a bit more power with a decat and by putting the air intake in front of the radiators. The battery on that looks to be blocking the stock cold air feed location and the air filter will be pulling air heated by the expansion tank. A few detail changes and he\'d see more power quite easily. What sort of management is he using?
Ben, the turbo on the greddy kit sits quite close to the manifold under the intake manifold. It\'s hard to see unless you take the right hand wheel off! SPR\'s turbo for the RX8 sits where the Battery is but the greddy kit is meant to be the most straightforward to install.
your not kidding - it looks like a bit of a faff and designed by an idiot!
looking at this

ontop ofg all the other stupid mistakes youve already listed the down pipe pass\'s right past the intake - now correct me if im wrong but carnt rotary exhaust gases reach temps as high as 2000*f WOT? carnt be too good for getting that cold air in the through the ports when your runners are glowing red hot :rollin
The downpipe on FDs goes past the LIM too, nothing wrong with some good heat shielding though
I think it was rushed to the market to satisfy the demand for forced induction for the RX8, like Blitz did with their supercharger kit. I don\'t know about later ones but early ones had problems with the piggy back fighting with the stock ECU and causing CELs and loss of power, I also seem to remember that you have to block off the tertiary ports on a high power RX8 as the management system couldn\'t cope with opening and closing them.

It is infact 100 BHP more than a totally stock FC and my FC\'s engine was rebuilt around 20k ago and runs 220bhp with only a tame aftermarket exhaust. I do agree the 8 has a much better chassis, but the FC\'s is quite good with a few tweeks! But at leastmine has not lost too many ponies ;)
I\'m sorry i don\'t know much more about the RX-8, i think he said he was running .7 bar of boost. I am also not positive about the managment, he did tell me but i forgot. I also thought the battery was in a strange place, if you putting all that money into a boosted RX-8 you\'d have thought he\'d at least relocate battery to the boot.
Tis a good point to be made actually - the nature of the rotary engine means it performs better at higher revs, as sealing gets better - meaning top end power loss is no where near the same as with a piston engine. The problems are all at the low end (idling, cruise, starting) with \'old and tired\' rotaries.
The RX8 isn\'t the easiest of engines to Turbo - due to higher compression rotors and the exhaust port designs - those early Greddy kits used the blue emanage, but the later kits come with the ultimate - I got a lot of good info off some of their tuning sites in the US ;)
An RX8 with the same power as an FC is going to probably out corner and out break and FC with ease - an FD may be a bit more of a challenge - but don\'t write them off - the 8 is a killer on the track :)
I wonder what would happen to a higher mileage rotary engine if water Injection was added? As it would clear any carbon deposits and possibly cause the engine to lose compression?
