T.T.T Tapshift

Looking into getting a 05 Comp G and using it as a rally cross car, And I made a post on some facebook pages asking this question, but there was alot of back and forth about bell housings, and gear ratios.

What I want a solid answer to, is:

Due to the CompG having a tapshift transmission, yada yada yada. If it fails due to the constant abuse (which i know it's going to). Is it possible to just slap a trans from any 97-08 (or so) GTP, keep running it. Or will i need to find another tap shift trans.


thanks guys
 


Tapshift with 4 gears is about as useless as a ratchet wrench that can not ratchet. All of us who use it, pretty much think it is useless and we don't bother. 2nd gear tops in around 75-80mph and you will never see that on a RallyX stage.

The other aspect is the abuse, it will cook and probably break before long.

Then there is the FWD aspect, I don't care what most of the RallyXers say, but RWD and AWD are the better options here to have more fun, sure FWD can do it, but I would pick something along those lines.

I wouldn't spend more than $2000 on a RallyX car either, to start, if you get real serious then I could see a more potent vehicle is useful. So spending the money on this is really just a hobby, so I would keep the budget down...way down.

I don't rallyX...yet but I have friends who do, B14 Nissan Sentra (This I know is FWD), BMW e30/e36, 90's Subies. Anything that is either AWD or RWD with a manual is your best option to have more fun. With that in mind a FWD/Auto/3,600-3,700lbs is going to dampen that.
 
I thought long and hard about what I want when I do enter the world of RallyX and it is a 1990's BMW e36 318ti manual. Tiny package, 2,700lbs, RWD, and cheap engine swap galore. You can have one for less than $2,000, either keep the 4cylinder (which is a viable solution too) or drop in an M50/52. Raise the suspension, drop in some seats that will fit me, snow/mud tires on it and away I will go.

Check out what some people have and work with on grassroot motorsports forums.

You can slap in another trans from a gtp, you will throw a CEL until you tell the PCM that it is geared at 2.93.

so if i just gave 0 f***s about a CEL light, i could get away with any gtp trans

As you said E30's or E36 beemers, yeah thats great and all, but where i live at. thoese types of car's are non existent. nobody has those. But gp's are a dime a dozen. Easier to go the the wreckers around here and get a part off a gp, than it would be trying to hunt something down for some "euro import exotic" type car

Gp's are cheap, and to me, cheap and readily avaiable, is what i want
 
The tap shift transmissions have a beefier 1st gear band and 4th gear clutch, as well as a different Valve Body / Channel Plate assembly (As well as a different gear ratio).

You have a couple options though. You could build a non-tap shift trans with the old (Tap Shift) valve body / channel plate / gears. You could also put in a non-tap shift trans, and replace the ECU with a stock GTP ECU. Going that route you would lose ABS / Stability control though. If you swapped out the EBTCM with a GTP, you would be ok (Still losing stability control, but re-gaining ABS / TCS).

My car is a GT, running a CompG Motor and Trans (With a GTP Valve Body / Channel Plate) and a GTP ECU (Re-programmed for 3.29's) and EBTCM.
