I've been reading around and doing searchs about it and I keep seeing post saying that it woudl take at least $20k to get a 20b into an FD even if you did the work yourself.

How is that? I was adding some numbers and to get just a stock 20b into an FD I'm coming up with around $8k (which is still out of my price range lol). Am I missing something?

$4.5 for a used 20b with turbos, accesories, ECU. ect
$2k for a subframe
$1.5 for an intercooler and misc. things that pop up.
FREE: Blood, sweat, and tears

of coarse this is assuming no rebuild, and assuming you do allth e work yourself. Kinda half assing but it would be in and running.

So how does everyone come up with this 20-25K for parts?

 

Petit calls it the Bonzai package I beleive and I think the whole conversion (they do everything) is estimated 30k depending on your car.

 

its banzai.....

i think theres a bunch of custom fab stuff needed too.

 

its not quite the 20-25k if you do it yourself but def. that if you pay a shop
pettit charges 40k i believe but they rebuild the engine

trust me I did a lot of research on this. the main problem is the wiring and the ecu. The stock ecu for the 20b knows how to run an auto tranny only. Some people have said that it works or gotten it to work but whats the point you have stock like horsepower numbers. you have to get a haltech and wire it up and then tune the car. Plus the mounting isnt as easy as everyone says.

I think its something you have to really want to do to be different from everyone. because our motor can put out whatever hp we want. maybe not as reliable as a 20b would be but still its a lot of work and its easier to go through 3 motors at least.

 

what custom stuff? From what I've researched so far the FD trans and clutch bolt right up, and someone was making a subframe that used the FD motor mounts. The trans stays in the same place so there is no fiddling with a custom driveshaft or PPF. The wiring sounds like hell (I really hate doing wiring), but doable.

The hardest part seems to be relocating things like p/s lines, a/c lines, intercooler, rad, ect since that will all have to be custom lines, pipes, and brackets.

Of coarse this isn't for hardcore racing and tuning, thats why I didn't include rebuild, porting, jumbo size turbos, stand alone, ect. But it would be in the car and running.

 

Build it, and you will find out.

 

I'm actually thinking about doing it.

 

provide the bank for it and I'll gladly attempt lol

 

Isn't there a 20b FAQ file?

 

I spent about $15k taking my bone stock FD and 3 rotoring it.

When I did my install I used all the factory A/C and PS lines. I used a Greddy 3-row intercooler and modified greddy's radiator mounts to get the Koyo more virticle. This have me enought room to fit the 20b and still use the stock fans.

 

Do you have a list breaking down the price of everything?

Hehehe, that's my point. All of those people who think it doesn't cost much need to try it themselves. In my experience, hotrodders tend to only list certain vital hard parts when telling others what they spent on a project. Somehow they always forget to include the "little" costs, and they always fail to mention their huge investment in tooling and the skills required to keep from paying a professional for skilled labor. My Monster Garage example:
We built a 20B RX-7 for under $3,000!
$500 RX-7
$2,000 Incredibly bad 20B that will not last longer than the show.
$0 Haltech E11 - Freebie!
$0 GReddy Intercooler - Freebie!
$0 Killer paint job that would cost anybody else at least $2,000
$0 All kinds of other Freebies that totally distort the real cost.
$0 Hundreds of thousands of dollars in tools, equipment, and facilities.
$0 A team of some of the best mechanics in the country.

Also, I think it's funny when people think that they can save money by doing all the work themselves but they have no idea what they are doing.

RETed's site has a good breakdown of the parts and pricing of the main components, but it is difficult to determine the cost of the smaller components and labor since this really depends a lot on how the individual performs the conversion. His EMS charts are still not complete.

I agree IronMdnX, I figured 15 to 20K when I first strart'd my project. So far I've spent about 10K and I still have to buy ECU($1500) Turbo($1350) Manifold($650) Radiator and Fans($670) Intercooler($1000) Injectors,BOV,Wastegate,Coilpacks,Plugs,Wires,Cust om Piping($3-5K) and then I still have the Fuel system($1-2K) Plus misc. stuff

 

Here is a quick list. I'm sure i missed a few things

2900 Motor
2200 Subframe / Spindles
650 DownPipe / Intercooler piping from Derrick
369 Koyo Radiator
195 Greddy Type-R BOV
1350 Greddy 3 row intercooler
125 Greddy Elbow
1000 Earls fittings, lines, fuel filters, oil thermostat, 2 oil coolers
150 Aeromotive FRP
350 Apex r33 Fuel Pump
215 Supra Fuel Pump
60 Homemade fuel rail
280 3 1680cc injectors
1250 AEM computer

IronMdnX

I like your y-pipe

maybe you can get that 2nd filter a little closer to the ground

is there a way to keep the twins in sequential it looks like you have it non seq. Why not go single turbo then? cost or what? And how did you decide which turbos to use the cosmo or twins?
Was that 15k with all the labor yourself?

sweet *** fuc_ing car~!!!!!!

 

 

SurgeMonster, you need the stock ECU to run seq.




Hey Iron, how the car been running since you fixed the oil leak. Any major headaches lately? Hows the power feel on the non rebuilt block?

 

The car has been put away for the past few months due to winter here in MN. I only was able to put on about 300-400 miles. I was having a few problems with the staged injection, but figured out what i was doing wrong. I'm just itching for spring!!

 

no because unlike the normal fd, every 20b ends up different. on the fd theres at least 3-4 different ways to mount the engine in the car alone.

besides its almost one of those if you have to ask the answer is no questions, all the info is in the 20b section

 

We should have a FAQ post for this conversion as it gets asked so many times. You can bench race to death how much the conversion will cost. Speaking as someone who has done it, take your budget and add at least 40% and you should be fine.

 

HinsonSuperCars.com is now offering bolt in subframe solutions for the 20B. There is no modification to the spindles, and we are priced well below our competition. For more information, please see our website and contact us directly.

sorry mispost

 

are there places to get front cosmo clips? Seems like the process could be much simlpified by this, as it would come with all the wiring hooked up, radiator, ecu, engine, transmission, subframe that could be modified or at least used, guage cluster that might be able to be modified, intercooler, piping that might be able to be used. (all these are possibles, i have no intention of doing this swap and havent really looked into it, but have researched many like it and decided for myself i would probably never do a motor swap that wasnt sold in this country if i didnt get a front clip).
