This thread is specifically for discussing the building of the drag car.

To start the discussion, we need to choose the appropriate chassis. We have three choices thus far:

$100T2 (Me) has offered an FB.

EZMONEY has offered an FD rolling chassis for $1500.

Another forum member has offered an FC for $300.

My particular point of view is to use the FB. Not just because I'm the guy donating it, but because it has several advantages. It's lighter, which means it will need less power to go fast. It doesn't have IRS, so swapping in a Ford 9" will be pretty straightforward (or so another member has claimed). Also, because it is lighter, there will hopefully not be as much breakage of parts from stress.

What do you guys think?

 

I vote the fb, seeing as it is the lightest and...free-est. That will save some money for the motor build and drivetrain.

 

Just throwing this out there. My FD still has the carpet, headliner, visors, misc. plastic pieces that I can take out and sell by themselves which will get the cost of my FD lower, possibley down as low as $500.

 

I also vote for the FB, possibly with a TII engine. Parts for the first 2 gens are a lot more common and cheaper than the FD.

 

First gen FTW. A TII swap isn't too bad once you know what your doing. I am finishing one up in my GSL-SE.

 

I also vote FB drag car

 

Fb-rew

Ftw

 

We should keep our feets on the ground, as $100T2 said. A 13b-rew in a FB insn't cheap or even really realistic.

 

OK, to make this process more helpful, let's do a couple things:

-If you're going to suggest a combo, back it up with rational thought.

-Stop the "FTW" and "TeH 7 Can'T Lose" stuff. Let's look at this as professionally as we can. To quote Bull Durham, "Think classy, you'll be classy."

-Unless you own one and plan to donate it, no 20B talk either. Again, 100% realistic. This isn't "Pimp My Ride" or "Overhaulin'" where your dream car is going to be built. I'm going to keep being the sledgehammer of reality on these discussions.

I think we need to go FB and either a turbo 12A or turbo 13B. If RotaryShack can build a 680 HP 12A, they are worth considering, and then we wouldn't need to get a GSL-SE front cover, screw with engine mounts, etc. 13Bs are fine choices too, I don't, however, think we need a "full T2 swap", because bottom line, we're going to have to do some sort of porting and run a completely different turbo than a T2. Plus, we're not going to be able to use any of the T2 ECU stuff or what not. No sense shelling out the money for stuff we don't need.

So, we need a T2 short block and a T2 transmission. Heavy duty clutch, right? Crispeed, if you're following this thread, it seems you have more drag experience than most everyone, what combinations have you had success with?

 

Ok easy already. TII swaps aren't too hard but aren't necessarily cheap either if your doing a full swap. As far as the stock ECU, it is too much of a pain to get wired with the stock harness so I'm with you on that. TII is a good base though and has plenty of support and isn't too bad for short blocks. Just need GSL-SE pan, cover, and tap a turbo oil return line in the front cover. Then it will pretty much drop in.

 

fb with a 12a bridge with 150shot of nos should be straight. then the rest is up with the gearing of the car,

 

I just want to stick my nose in it and say:

FB with a 13BT seems to be the obvious choice to me... it's less a question of what to build and more of how to build it. What are the best ideas for porting and other engine mods, size of turbo, EMS(and who can tune it), etc...

But I'm no engine builder so I can't be much help here

 

FB with a Cosmo RE 13B.

I'm not sure what they are like to get in the US, but in Canada I can get Cosmo RE motors for less than $1500 CDN. The RE motor is better than the REW anyways.

If I had my front subframe and rack and pinion convertion kit finished I'd donate one for sure. It would allow a T2 or RE motor swap to be done VERY easily. Check out this thread for more details https://www.rx7club.com/showthread.php?t=647333

 

i'd say fb because I want the 500 dollar fd hey ezmoney you wana sell that to me for 500 bucks? Is it rolling chassis? Anyways On topic are you guys saying you want to make a 10 second car out of an n/a and nitrous? Remember a standalone is going to be needed either way. Also it may be cheaper to go turbo. I'm not sure though, maybe ask someone with some 10 second n/a's out there but that is no small task. I think it's easier to make a turbo charged 7 get down in the 10's.

 

I have the t2 swap in the FB very fast 0-90 in less than 10 seconds without a solid launch


I vote fb t2 swap

though i have msd6a directfire and fun stuff like that

 

I vote FB, being the lightest car. Also, it seems the 3tc guys are going with an old-school car, so I think it'd be more interesting from the show producer's point of view to have an old-school shootout.

I'm not 100% certain on the specs of the 12a, such as compression ratios and the like, but I think that a heavily ported, high-compression boosted 13b would be the best choice with the info I have. 13b-T from an FC, 13b-re from a Cosmo, whichever is the best as far as ease of dropping in and having it work.

I also think that a haltech/megasquirt/some sort of EMS is going to be needed, so the stock ECU of the donor car is a moot point.


Sorry I don't have much experience with drag racing, or else I'd offer something donation wise.

 

Depending on the size of the turbo the forum would like to go with, I may be able to supply us one for cheap, maybe even free. It would be something from a diesel shop. Possably a Holset H1E, H2C, Schwitzer 3LM, or even some of the monster Garrett turbos off of semi's.....Just a thought.

 

Only problem with the large Garrett's on trucks is the astonisingly small hotsides....

I have to agree on the nitrous motor being difficult. I thought about it more and more and by the time the car is dialed into to something *AROUND* 10 seconds we'll have gone through 6 engines.

I'm thinking cheapest/lightest/easiest route is going to be $100T2's FB, a nice big turbo (I'm thinking T04-R....that should net enough power) and plenty of fuel. I have a pair of cheap 1000cc's we can use as primaires

Management would be whatever we can secure cheaply within the forum or with donations. Most will work, so there's no need to drop cash for an E11v2 or something outlandish. A used LT8 with harness, used E6K or E6X, an MS that's already built....if we do a TII engine swap we could use a PFC also. Plenty of options here.

FB is definetly the way to go though IMHO.

I have some CLEAN FC rads that we can use also, they'll swap almost directly into the FB chassis.

Any pics of any of the potential chassis'?

I posted in the other thread but Ill post up here to. I have a 95 13btt motor I was putting in my rx-2. It already is has a act clutch and a shortened t2 tranny, perfect for the swap into an fb. I was told it runs but if we are going to be racing it, its going to need to be rebiult so if someone is willing to rebiuld it im willing to offer it up. If we win I get the motor and tranny back, if we lose then I guess I get to try and find something else to put in my Rx-2 lol. And I get to drive it!!! lol J/k but really though if you need a driver im down.

Chris

 

OK so after debating with myself heres what im willing to offer. I have been waiting for something to do with my rx-2. If we can get enough support to finish the biuld-up Ill offer it up for the chance for it to be imortalized on tv. Its about 60% done. Things needed are turbo kit, engine rebiuld, brake lines ran, its going to need a rear end, drive shaft, stand alone, better suspension,( front has already been changed to FB. Let me know what you guys think. last time I had the car weighed it was around 1700lbs. Back in the day i ran 14.4 with a proven 118hp lol and no traction. This thing can run easy 10's here are some pictures let me know whos in.

Chris

 

What are you looking to get for it?

 

Simple if we win I get my car back... If we lose at least i did something with it that will be imortalized on TV. I get to negotiate at the show though. My grandfather bought it brand new in 72, gave it to my dad in 82' my dad gave it to me in 98' its time it did something. The car we win will be sold and the money will be devided among anyone who put in work or contributed parts.

Chris

 

So what are the chances of this going down for real? I can get the role cage biult for it and do most of the work myself. I will need someone to biuld the motor who is reputable and someone to tune it. As far as putting it together I can do that.

Chris

 

Just so you know, you don't need an -SE front cover to put a 13b in an FB. The 12a front cover isn't any different that I can tell... I've used a 12a front cover for both my S4 TII and REW motor incarnations in my FB.

Use a 13b, if for no other reason that you can get a T04 manifold for them used on the cheap. 12a turbo manifolds are hard to come by, no matter the price.
