Some Project Ideas... Opinions Welcomed!

Okay I have a nice 82' that's just begging for her to be a mad Street/Drift Racer.

She's already got a Tokico suspension and front sway bars, some light cleaning and tuning on the engine. I am getting a set of Sparco Style Reclinables with a 4 point Cam-lock harness in a month or two, when ever the company has a new shipment...

But here are some Ideas I had for the future;

One is getting a hold of a wrecked or Parts RX-8 ripping the hubs, rotors, calipers, and wheels off and machining them onto my spindles. ((or should I just try and find a way to splice the axles?)) Also getting that nice 13B-MSE out of the RX-8 And dropping it into my cozy little bay.

Two I was thinking of either Twin Turbo, or a Porche Variable Geometry Turbo...

Also thinking of getting a Areo Kit and extending my frame out so I can fit a v mounted raidator, and twin intercoolers in the corners.

I was going to try and machine Teins into the wells and get some heavier sway bars and links. Definetly strut bars and stiffening goodies.

All LEDs except for the headlights and reworked interior, mostly like the orginal, but more resistant parts.

I know a hell of a projects list, but I love my baby and she is gonna be with me for a while...

Plus, unlike your girlfriend, she'll always be there for you and if you take good care of you she'll always be ready to take you for a ride :P

You have a lot more thinking to do. Also, if you want to get all the goodies, read up on what it takes to run that setup. The set up you described will be very expensive, tons more than the average or even above average 1st gen owner would do.

Why do you want the RX8 hubs/spindles/etc? Buying the Respeed Big Brake kit will be plenty more than what you will need and will provide with a better braking set up than the stock RX8, not to mention the costs will be ultra low comparatively.

Why twin intercoolers? The stock RX8 will not hold to the amount of power needed for the dual intercoolers. The pressure drops you have to take into consideration. The RX7 is not a regular car. If it does not get the adequate cooling for the engine in the first place, it will overheat and die. Also, not just any turbo will work with any engine.

Tiens, are you talking about springs? If you are going to replace suspension, Tokico's are perfect for the street, Blues or Illumina's on a lower setting. If you want to go all out and get coilovers, then you will find that tuning coilovers for a race track, and then driving it on the street will require a new backbone for yourself as well.

Take a look in the archives and read on some threads. You will find out that not always is the newest thing out there the best thing. The 13bt out of the TII will suit your needs perfectly.

Also, we do not condone street racing. They have tracks for this stuff.

The twin intercoolers are only for if I decide on twin turbos.. The VGT from a proche supposedly adjusts for low and high end RPM... and after hearing about the TII swap I've been wondering if a NA set up will be better. As for the RX-8 Setup, I was looking for a cheaper mid point setup by findinga wrecked one to salvage parts off of.

Though you're right about the cost, I been thinking over like 5-years XD maybe 10. >.> The coil-overs are more for street/track use so I was thinking Tein's Mono Flex system...
I've been thinking of some interesting cooling setups, but they are more ideas now, need more research in them..

Also, The street-racing thing is for more legally setup events. As for the back bone, I was wondering what kind of chassis modifcation would be required....

Thanks for the help though ^.^ greatly appreciated... I was wondering how well the setup might work, better to do this in the planning stages than after I buy it all XD LoL

Twin turbos do not need twin intercoolers. NA set ups will only go so far, I believe 300hp max on a PP engine, and that is not really streetable unless you know what you are doing. Even then, it will not have 300hp.

Turbo is the way to go, and the VATN turbos are generally very expensive and not worth the cost.


EDIT: It seems like I am coming off and slamming you here. Just saying I am not, just that tons of these questions can and have been answered in past threads. A lot of work and planning goes into these. Plus, you do not need 800hp to drift. My car has about 140 and can go around turns just as sideways as they can.

Naw, you're not. I am going for an industrial design major, and I know a lot of teh planning that goes with tuning a car. Its why I asked for your opinion, I wanted to hear your ideas on the specific setup. As for the VGT I don't know much about it, so thanks for letting me know that its not worth the money.

I want meh car to be a decent racer and drifter, kinda a hybrid on those fields. I am not really thinking more than 400hp ((i'd be lucky to get more than that)) and I think a NA motor might be more responsive to that racing style ((god knows its already mid 2000 lbs, the power to weight ration would be wonderful with just a 200-300hp range))

Would it be possible to tune the 12A to those type of specs? I am asking the fourm, because I have very intricate questions that I'd rather hear from people than older messeges, otherwise I would have just looked into people's old stories.

^.^ Srry if I seem kinda pushy, just like discussing something more than reading up on it and thats all, ya know?

No prob. Just turbo the 12a. Easier said than done, but that will give you somewhere near the 200hp mark. Bad83 has a turboed 12a, pushing 12lbs of boost. His ride is a blast.

Bridgeport the 12a and see where that takes you. Go to the dyno sticky at the top of the page and see what power levels you want and see their set up.

The Rx8 engine is a pretty bad platform, not very much aftermarket research has been done on them. Any engine can get you to the horsepower level you want really with a turbo setup.

As for the braking plus one on the T2 kit from ReSpeed.com. Not only will it be cheaper, you don't have to get the rotors machined everytime you have to place new ones in. Just direct drop in. And them being the 4 piston ones will provide more than enough to stop your car. If you can lock up all your 4 tires, you're definatly not underbraked, more under grip from your tires them self. Wider more grippy tires go a long way.

For the porche turbo charger setup, for one try finding one like that for cheap, 2 try to find someone that can really tune that thing properly. From my understanding, that is actually not a twin turbo charger setup but a single turbo charger that switches somehow, but don't quote me on that.

For suspension for what you're be doing the tokico illuminas will probably be the best setup for you. As for springs, thats whole different world of what you want to do.

From my research you can get up to 250hp out of the 12a with a turbo. After that you have to get into higher-end internals. A turbo 13b would get you plenty as well if you're willing to spend the kind of money you're talking about.
I think the porsche variable turbo isn't a twin turbo, but has twin compressors so it uses the small one in low RPM and switches to the big one at higher RPMS. But actually getting that to work on another car would be a hell of a headache. Just get a turbo that is well sized for your application and it will work just fine.

Acctually The Porche Variable Geomtery Turbo is a single turbo. Its set up with a small CPU so that at lower RPS adjustable fins on the hot side of the turbo constrain exhuast flow on the turbine and they open up at higher RPMs. A really cool idea, they stole it from Mistubishi back in the Starrion Development, but at that time Mistu couldn't develop it well anyways.

That was my alternative to twin or a medium sized turbo.

Also, how much HP can I get out a 12A if I decide to go the NA route?
Also, I have a hard time finding information on this, so I will just ask now, where can I get a 4 to five stud adapter for my wheels? I know Nissan S13's have a kit for their 4 Bolt pattern and so do some of the older cars, does a FB have one?

The Porsche turbo may not be like this for sure, but they make a turbocharger(precision's got a series, IIRC) that can change the pitch of is compressor/turbine blades to create/reduce backpressure and be more/less effecient in boosting. This allows it to be very restrictive at low rpms, for good spool, and drop the back pressure and be more efficient at the top end, so that you dont run out of steam. I have seen them for cars, but never tried one - they use them on desiel trucks too.

Yes. Although some people take the 3rd member out and put it in their cars and still run the drums.

no, not at the wheels, and not without making it undrivable in the streets. I am tellin ya, Forced induction is the way to go for your needs.

TII engine in good shape, hell, even street ported could be netted for $2000
TII Transmission perfect, 500$.
Tokico Illumina's, RB Springs and sway bars $1000 (if all new parts)
Custom driveshaft, 300$
Complete Mark 1 Big Brake upgrade, with rebuilt calipers/new rotors/good brake pads, 600$

Not to mention that the rear end on our cars can handle about 200-225hp before shredding itself. That is when you drive it like you stole it. Either way, it will be a costly project, and I haven't gotten into the nitty gritty. I will leave that to you and the search button

Ahh.... So I couldn't just swap out my rear, tranny and engine for 13B and some 2nd or third gen parts? I was hoping that you could stroke a 13B at least to that range u.u ... But I guess FI will work too..

Thanks....

1st gens are solid rear axles and converting to the later style would be a big undertaking...they make harded axle kits I beleive for these axles, not to mention, if worse came to worse, you can swap to a Ford 9" or something...you could always join the ranks of bastardization and drop in a V8 or something....Granny's Speed Shop has everything you would need - engine to axle.
