I'm just going to try to keep it short. I have an 07 6 Speed rebuilt engine. It's Street and exhaust ported. Looking for an aggressive DD that loves to be taken to the track.
Here's my goodies list

• TurboXs catback exhaust
• TurboXs garage line headders (ceramic coated and wrapped)
• EGR delete (welcome to southcarolina)
• Bennettbuilt ignition system
• NGK spark plugs
• BHR lightweight pulleys
• Spec stage 2 clutch (overkill but I hear some boost net build)
• Spec flywheel and counterwights
• Re-medy water pump (Track purposes)
• Silicone hoses
• Misimoto thermostat
• Aluminium radiator
• Sohn adapter kit "will I still need to premix because 1st gens only have one injector"
• A/C delete (I don't use it so lose it)
• Vfad delete (blocking air)
• Throttle body coolant blocked off (heats cool air)
• LBR Aero plate
• LBR Underpinning

I think that's all of it. The engine is not yet in bet it should be within the next mouth or so. Once it is in, ill be getting Mazdaedit sortly after and try taking advantage of a few thing. Is there any other things to help with reliability/performance while keeping the car naturally asperated.

I'm not doing any suspension type thing for now seeing that the rx8 is arguably one of the best handling factory cars out.

P.S. the only parts on my car prior to the swap was

• TurboXs catback exhaust
• K&N intake
• Silicone hoses
• Aluminium radiator

So I can't tell give you guys my 2 cents just yet.

Thanks, Plus

EGR? We only have internal EGR from the side exhaust port design. You are probably thinking about the secondary air pump, which you can get rid of if you don't have a cat.

Also, BHR has come out with some new designs for their coils, which are much more easy to install. Maybe you should have a lookse.

StreetTrackPlus

Yes your completely right. Just used to calling it an egr. I just can't justify spending twice as much for BHR coils over bennettbuilt. I know BHR has the best reputation but the cost just isn't their.

Thanks for responding!

Sounds like a fun build, but your priorities for a track car should be:
1. Safety
2. Reliability
3. Grip
4. Weight reduction
5. Power

I added some comments in bold above.

Be safe out there!

StreetTrackPlus

Love the feed back. Track days won't be for awhile. For the reasons you pointed out.

• Grip - looking at Achilles ATR Sport2 surprisingly good reviews
• Safety - None any ideas?
• Reliability - most parts i ordered are for relaving the engine of stress & heat rather then power "pulleys, flywheel, etc
• Weight - I can see taking out all the speakers but I can't see myself gutting the interior (pannles & seats) any other options?
• Power - I can't see getting anymore power without either super or turbo charging. (Won't be happening this engines lifespans)

Thanks for all the help Steve. How are you pulling almost 2gs?!?! Your not talking about brake force G's are you lol JK. I'll have a lot of ecu tunning for the next few months. While I worry about getting wheels, harness, etc.

It's $529 shipped for the BHR coils with spark plugs and wires vs. $395 plus shipping for the comparable Bennett Built kit. I'd follow's Steve's advice and use the money you'll save to by the BHR coils.

StreetTrackPlus

Well I already have everything I listed. I figured I would get hell on here if I just posted my wish list build lol. But I got the coil bracket for free coils and wires totalled $244 after shipping. BHR for just coils and wires is $449 before shipping.
And if anyone is buying NGK spark plugs from anywhere other then RockAuto, Amazon, or possibly eBay your getting ripped off. Im all for BHR coil if you have it like that but, still charging $100 a coil because you where the 1st to the punch is just to much!!! Especially when your competitors are very close to or even on par with your quality. This has been a slow build buying parts one buy one the past 3 years just waiting to blow the engine.... finaly everythings coming together and I'm about to put the parts to work. This might be my first posting but I've been on here reading for about 4 years. I've seen what happens when you don't read on forum's.
Glad to be taken easy on.

Steve's advice is sound. You don't need most of the stuff on the list, and you really need more suspension. Also brake pads? Lighter battery? Weight reduction? Lighter wheels?
The Renesis' potential for more power over stock is pretty limited, so focus on making the best of the chassis. It'll never be a Mustang, but it will easy catch up to one on good tires and a suspension upgrade.

Also did I see K&N intake on there? Get rid of that travesty, that will make you more net power than the other listed mods combined.

UnknownJinX

In regards to BHR coils: they are overhauled now and have a completely different design. They are literally plug and play with OEM coils now. No bulky bracket or extra ground wire to work with anymore.

And yeah, tuning won't get you much more power... If you want major power upgrade, just get a blower. Staying NA won't get you too far from stock power level.

StreetTrackPlus

Had no clue about that! That changes everything I said about them.... I imagine all those extra wires looks a mess compared to that. 🤔

StreetTrackPlus

Nor would I ever want it to be a Mustang!!! Lol.

Ahh you seen it..... Sadly yes. I do have a K&N intake. Something I'm hoping a tune will help with. I'd like to say in the future I'll swap to aem instead.

As far as suspension I'm really interests in ohlins just not realistic. Tires on are the list. Wheels I'm going to get the 40th anniversary. Brake, rotors, calipers I haven't looked into much honestly "ALL EARS".

Light battery is defiantly on the list now! Thanks any brand/type you recommend just has to be able to be daily drivable when need.

OEM wheels are heavy, no point in using those for track duty. Get something light and in 17" size.
You can keep the original rotors if they're in spec, but get racing brake pads for when you go out. Swap them in at the same time as you swap your track tires before the event.
No need to change calipers.

Regarding the K&N: go back to stock if you can. There's nothing to be gained on these cars from upgrading the intake, and the K&N in particular has caused many others unstable idles and other problems that you can't tune out.

Steve Dallas

So, this isn't really a track car build. This is a street car that will see occasional HPDE time. Got it.

Wheels and Tires: Get some lightweight rims in size 17x9. Wrap them in good 235 or 245 rubber
Brakes: Install brake ducts and get a set of track pads. I run Carbotech XP10 F and XP8 R on the track and 1521 on the street on the same rotors. Flush the system with fresh DOT 4 fluid. Brakes are your most important upgrade; don't skimp here
Suspension: Learn on your stock suspension for at least a year, if you are new to the track. After that, you don't need Ohlins. These will do just fine. The ONLY other coilovers you should be considering are Bilstein PSS (B14) and Fortune 500, depending on your priorities
Engine: Get rid of that horrid hot air intake. Return to stock (without VFAD is fine) or get AEM or Racing Beat. You won't gain much from tuning, and you can't tune the suck out of that K&N intake

StreetTrackPlus

Exactly. It won't be a full track car yet. I'm going for a car I can take to the track any weekend and just have to change the fluids, brakes, & tires. I know that can be any car technically but...

So brakes, tires, wheel, and of course toss the hot air intake. As far as suspension im definitely holding off on. Much rather get comfortable with the cars limits as is. I've only taken it to the limit a hand full of time.

Sorry bout the Track build title. It was probable the best way to get the constructive criticism I was looking for though. I just didn't want to post a wish list build of a bunch of parts i don't have yet.
