20B swap?
Hey I was wondering what the cost would be for this swap? I found the engine for $4000 with the ecu at corksport, then you need a tranny(which one?) & an intercooler(or does one come with?) & change the exhaust. How much would all of the parts cost, without labor? Thanks alot.

i heard around mid $20,000's from peter ferrall, but he only does FD work, so it might be different from what you need. a 20B also req. the heat sheild to be moved back for clearance of motor.

if you have to ask you can't afford it :) I doubt it has an ECU. and if it does I don't think you would want to use it. you need custom motor mounts. you need to find a flywheel, clutch, and starter that will fit and be ok. and you use your tranny. well a turbo tranny. you'd bust up you N/A one pretty good. you will need an IC, bigger rad. you need a custom waterneck out of the housing.
and probably alot more :) there is a reason there are only a few running 20b's on the road. and alot of "project cars" |
it can be done for about 7000 grand with aftermarket ecu. if you are going to purchase the 20b with stock ecu be sure to ask them if it includes the coils. sometimes they do not.

Ya I think it comes with the stock ECU, they sell coils at akinsrotary.com for $150 a set, so thats another $450. Motor mounts would have to be made or what? How much should those run approximately? New radiator & intercooler. Hmmm..I don't see this as a $20,000 project at all. Looks like more around that $8-10,000. I could get the engine, ecu & tranny I need for around $4500. Plues the coils, so say $5,000. Then a new flywheel & clutch, so say $850 or so. Thats at $5800 now. Then an intercooler and radiator, so say $1500 or so. Thats $7,300. Then getting motor mounts made and a few other custom parts & labor. I would say around $9-10,000 roughly. Prolly end up more. I am not planning this just wondering. I was looking at the price for a rebuild/streetport & ot was $2300, and the 20B is $4000. Definitely will end up with a 20B in it after college is all done. Man I looked at www.atkinsrotary.com & they have a dyno sheet for a 20B with a single turbo with their fuel injection & ignition & its putting over 370hp to the ground. That would be a fast ass 2nd gen, especially if i was stripped. Could you imagine? I would say prolly mid 11s easy.

Originally posted by InitialD FC If you want 370 at the ground... a t04 kit will do that in a heartbeat. you dont need a 20b unless you are going for real power. I plan on gettin one sometime after i finish my setup and run around for a while on it. im shooting for almost twice that :eek: , and that is with 2 rotors... |
Ohh ok, yeah, you would do almost just as much work to get the turbo motor in there already, might as well go 20b! :D And its true, that motor will make some killer power without breaking a sweat.
|
Ya thats what I figure. Eventually I will do it I think. Instead of buying a new sports car I will just make my own that will be one of a kind(Iknow there are a few 20B FCs but mine will have a body kit and custom everything :D). Will be like 5 years though, o well will just have to make my NA as fast as possible for now.

This has been covered SOOOOOO many times, PLEASE use the search button.
To do it cheap, figure at least $10k. Evil has spent close to $35k already i think. |

Ya thats true, he does live right there. What road do you live off of anyways? Man I gotta do that conversion in a few years. Or maybe you will be tired of yours and want to sell it to me:D, doubt that.

Oh ya evil...ever see any TIIs for sale around here? I have never seen even one.

Gee, I end up sounding like a broken record already... :)
The stock ECU is WORTHLESS.  Repeat...don't fall for the trap that a seller is offering the ECU is worth money, cause (as someone already said), you need 1) the stock coil packs, and 2) the stock automatic transmission.  The auto trans programming is integrated into the stock ECU, so unless you fool the stock ECU that the stock auto trans is still working, the stock ECU will barf. With that said and done, this is what you're looking at... Haltech E6K $1,500 or Electromotive TEC-I $3,000 - you can't run true split trailing, but it'll make the engine run Upgrade clutch - ACT will hold up to 500hp $500 Lightened flywheel $300+ - the 20B only comes in auto trans, so it'll come with the flexplate + counterweight Custom oil lines $200 - you'll need to fab the front oil line to coil cooler + turbo lines Custom motor mounts $400 - K2RD sells them prefab'd for drop-in install Upgrade radiator $300+ - the stock FC radiator is not good enough; the 20B runs HOT Front mount intercooler $1,000+ - you'll need one Turbo system $2,000+ - you'll need one unless you convert the stock twins to non-sequential Fuel system upgrades $100+ - Walbro can support low 20B power outputs The stock twin turbos do fit, but you'll need to fab the downpipe.  The stock twin turbos are TINY and barely will make over 300hp to the wheels.  The stock fuel injectors barely can support 300hp to the wheels, so anything more will require more (or bigger) fuel injectors. The 20B will add about 100 lbs. more weight up front, but running stiffer springs (easy would be a custom Ground Control coilover set-up) will easily balance this. The stock steering can stay intact.  You'll need to mod the stock front anti-sway bar - you'll need to change it anyways due to the extra weight.  Paul at K2RD is trying to design a "speedway" front anti-sway bar that will clear the 20B front end - this speedway bar is like the FD front anti-sway bar with a torsion straight bar center with splined ends. The hood does not clear the stock 20B twin turbo piping and slightly rubs on the upper intake manifold.  You'll either have to cut the stock hood, shim, or go custom (fiberglass) hood. After all of that, if you do get it running, the rear tires will go up in smoke. :) The beauty of the 20B is not the high horsepower levels, but the increase in torque over the twin rotor 13B! -Ted |

My RX-7's are currently in St. Petersburg, and I usually work on them (or other RX-7's) once or twice a week when Scott is off work (Fri-Sun). You are welcome to ride along whenever you like. BTW, I just need to swap the 15gal fuel cell into the 84, and then I'll be driving it around Riverview. :) |
How much do you usually find TIIs for?

So what kind of condition are those in? I might be interested in one that might need some minor cosmetic work but with a pretty fresh engine in a little while. How much do you think you can find one like that for? Somewhere around $1500 or so? Or one with a blown engine for under $1000 maybe? Thanks alot.

Ya I will settle for the series 4, its lighter at least which I like. You can put a J-spec in there still right?

I like the way you think. The wife and kids don't, but they're wrong. :)
However, I fear that they may not have the character (self-discipline, drive, etc.) to push themselves to do it. I worked my way through college, and don't think of it as one the better times of my life. It certainly wasn't the easiest. As for the single turbo upgrade, the only reason to do that would be if I took the car on the One Lap of America. The RXX-7 already goes from zero to illegal in a heartbeat, so spending an additional $15,000 (or more) just doesn't seem necessary. |

(My friend gave me the 10th AE rims) It was just flooded. I had to put a fuel pump switch in it to make it driveable, but it'll last till I build an engine for it. I'm getting all the mods in place first though. Its actually rather quick despite its condition. I'll see what it does with my 3'' exhaust, 3'' TID, Walboro, FCD, BOV, etc... :) |
