As I am reading the Formula D rule book it states that the cars subframe cannot be altered at all.

How do some guys with v8 rx7's still pass tech?

The reason i ask is because I plan to build another FD just for drifting and I already have an ls1/t56. I was planning to throw that in the drift car, but I dont want to start something that wont pass tech. Next year I am looking to complete a full season of usdrift along with 2 formula D events.

Thank you,
Danny

 

I don't think there are any V8 FD running in Formula D -but I highly doubt they would not let you run as long as everything looks safe. Look at the tube chassis mid engine cars they are letting run. D1 rulebook this season was retarded.

As far as I know Mike Essa is the only V8 7 running in formula D and the FC conversion does not require subframe modification.

I would say for a drift car build an FC

 

Engine subframe or chassis subframe?

 

I guess the are talking about the engine subframe. Not the chassy!!!!

 

ok....My next question would be then............Does any other mazda subframe work on an FD?

 

^ no

S13/S14 running LS engines in FD have modified subframes. Email FD or call them...

 

Well no the onec I seen. People have the option to run the sikky kit. The daft innovastions kit has a modded subframe. I already contacted FD and Im waiting on their response.

 

Essa is the only one I know of as well. Who built the white FD a long time ago with the v8. They never got to use it since formula d changed motor swap rules.

I know your fab skills though from vadriven. See about mounting it in a legal unpretty way.

 

If you can't drive that well, I can see why you'd want a V8...

But why spend 5000 to get into FD, if you aren't going to win?

 

1. Thats not what I asked...lol.
2. I want a v8 because I already have another Fd with a borg warner making 425hp......
3. The car is being built to the highest standard, so not to hold me back.
4. Who said anything about winning? I just want to build a legal comp car...lol
5. Good try at being a dick though.

 

i would drive one first see if you like it...

 

2010 rules states:
8.3.4
Front cross member and/or front or rear sub-frame
Front and rear sub-frames and cross members must be stock and
available on the exact model that is competing in Formula Drift. The
subframe must also be mounted in the exact stock location, without
being moved in any plane.
Front subframes may only be modified to directly allow for oilpan /
starter clearance and steering rack relocation. The front subframe must
retain intact on at least one major member on one face that spans the
entire width of the subframe, thereby keeping the original dimensions of
the subframe intact. Any other modifications, cutting, welding,
strengthening, etc is not allowed.

 

and there you have it.

 

F#CK Formula D rule book. but yet u can have millen in his two hundred thousand dollar Hyundai. ya they did not mod that stuff at all. bull ****

 

Means you have can modify the front subframe anyway you want as long as you keep the mounts in the same general area under the guise of allowing more oil pan/rack clearance.

 

but it says any other modification, welding,strengthening, cutting, etc not allowed ???



getting my car to pass fd/proam tech is going to be a paaaiiinnn...

 

UPDATE:

I had a back and forth conversation thru email's with randy this is what he had to say.

Randy,

As I read sec 8.3.4 it states the the following. I want to build an fds3 LS1 but in order for me to clear the oilpan I have to mod the front subframe. Does 8.3.4 allow me to do this. The subframe will still be in the original location with OEM pick up points. I just need to make clearence for a an oil pan.

yes, as long as there is a "major" unmodified, member of the original S/F still intact
STOCK FD3S Front Subframe:

Using guide line 8.3.4 you can tell that one member of the subframe can be modified and the other stay OEM. Thanks for the contact brian W. Im picking up another FD shell for next year......WOOT

This rule makes it a little blurred, but it can be done. I only plan to do eastcoast comps atm and the only reason I am trying to do this is because I dont want to be limited into what series I can run. Randy is the Chief stewart for Fornula D. If he says I can do it then project FDls1 will start this winter.

 

Sure hope its a late model ls1, or has been rebuilt. Faulty oiling rings will rear theyre ugle face otherwise.

 

its a 98 camaro ls1 that I am rebuilding to handle anything I throw at it. I think I might just run the ls1 in my street fd and track the other fd with my build 13b rew w/ a borg warner. Hummmm.

 

Please explain "faulty oil ring"


OP: run a 3qt accusump -this is pretty much a must. Get ARP or Katech rod bolts -do a bit of research the 98 has different head studs that were later improved upon, valve springs and a timing chair may be a good idea as well.

 

i think a dry sump is your best bet, or making a crazy oil pan. your going to cut to much out of the subframe, with stock pan, the oil pan is big and hangs low u will make the subframe to weak. the headers will have to be short tube if u keep the stock subframe...

 

^^^ I agree a dysump is really nice -but really expensive. Accusump is the best affordable solution... for a good DS you spending thousands... for a accusump, high pressure oil pump and a few other goodies your going to land at about $1200 or so.

 

thats eccentially what I will be making. Do you think the forward most member on the OEM S/F can be left untouched and then reweld to the rear lca mounts? I havent gotten down to any measurements or looked at the subframe just yet. Im just gathering info to see If I can pull this off an make it legit.

 

i think there is room with the dry sump... u will not have to cut anything, just make mounts

 

Who are you Ballinmiami? You drive FL events? You're going to drive in FD next year?
