I know! I'm very impressed with engineering/custom work that goes into designing those pieces and Logan's knowledge on things.

I can't wait to get their kit!! I'll post it up once I get them

I dont really understand how so many people can spend upwards of 30k on there 20b swaps unless a shop is doing ALL the work.

If your smart and shop around you can easily have a killer NA setup for under 10k. However I am fortunate to use the resources at my university and from the local help with tuning and wiring.

Here is my break down if anyone is interested.

20b shortblock -- 1500 shipped, yeah I know I found a deal

20b rebuild -- all the goodies, heavy porting, balancing etc 4500-5000

(3) 13b housings -- price to be determined (prolly around 800)

Haltech platinum sport 2000 -- 1500

lS1 coils "smart coils" -- 150 bucks

Header -- 500 bucks in material (I did the fab work on it)

20b stock subframe mounts -- 100 bucks (again I did the fab work)

Electric meizere 55gpm waterpump refurbished -- 150 bucks

ITB's (untested) 250 bucks in material (again fabbed by me)

Misc. electronics, wiring, sensors -- 800

That is pretty much what I have into the car as it sits now. Its actually less than 10k more like 9k and everything is basically brand new. All the 13b related stuff I sold off almost covered the cost of the entire build so I pretty much broke even on a setup that will be more reliable, sound awesome, and make great power. I cant complain.

Those are some good prices and I look forward to seeing how it turns out. What are you doing for your subframe? The Defined kit looks pretty good. I used the Pettit/Rotary Specialties frame and it works well but it does require modified spindles. Either way, you'll need to add in the $1,500 or so cost for that also. And how about tuning? One the cheap side that would be $500. I've also heard the 13B new housings have shot up in price recently so I would be surprised if they would be under $500 a piece (Ray at Malloy quoted me $750 recently but I am sure they can be had for less). I'm missing a bunch of little things also but you get the point. It adds up quickly.

Now if you can do it all yourself, you'll end up at the $15,000 mark I'm confident. Factor in though selling off all the 13B parts and you'll knock off $6,000 or so from the price. The $30K you see frequently quoted is for the vast majority of us that can't do the work themselves. This is for a turbo setup which adds $5,000 easy into the mix. Most of us have spent way more than the $30K figure but I believe with proper planning, the job can be done for the $30K figure.

I am using the stock subframe, its very similar to logans kit. I did my own modifications to the steering rack etc. As far as tuning my buddy who tunes is amazing and is going to hook me up. I just paid for 3 T2 housings for a killer deal, so the price has been up a little bit.

The mounting the of the 20b only cost me 200 bucks in material. I bought some 3" aluminum round stock for the actual mounts and turned them down on the lathe and used some 1/4 mild steel plate for the mount brackets.

If anyone needs mounts let me know

Maybe you are on to developing the next 20B conversion kit Keep the updates coming.

You're missing...
Clutch
Radiator
Possibly oil cooler(s)

On the street, you might get away with "stock" parts, but throw this car on the track, and it's going to overheat.
That adds an easy grand...if not more like couple grand more on the budget.

I remember how many friends have shown me their build sheets estimating what their builds would cost. I generally found that multiplying by three worked out pretty well. Sometimes four.

I will also admit that when I was first doing this stuff, I made that same mistake. At least a mistake in hindsight. Others may be much more capable than I and my friends have been.

If you do the porting and rebuilding youself can save $4500 which is my plan for my 20B FC.

I agree with David... It does add up. Just recent months I've spent few grand and I'm still not even close to being done.. It just adds up...

I've now given up on the NA 20B idea for the RX3 and decided to build another FI engine to have it as a spare for the Cosmo... and maybe go with BNR's upgraded twins for it. I've heard from some AU/NZ guys that BNR's turbo is making great power and great response for the Cosmo.

Thats funny b/c I don't hear from those guys. I am glad that the upgrades are working out for them . I hook you up!

[charlies7]

Lol nah...

Logan has much more R&D into than me..I am just keeping it simple and making it work with what I want..I dont have PS, AC or anything. However look out for a universal (interchangeable) intake setup..Models to come soon I hope.

[gmonsen]

I will be very curious to see how this works out. I spent what I thought was a fair amount of money building my NA 20b. However, I paid a shop to do it. Even so, if you get this up and running and producing good power at these prices, you should sell a manual and video and everyone will be running them.

Your expected total costs are less than many 13b rebuilds...

A full 20b install will run about $25,000 over here at www.rx7store.net. That price include single turbo, ported motor, clutch, fuel, computer and etc.
FYI! here is a teaser pic of a motor I'm working on right now, this will be one badass motor. I should have it done in about a week.

I think there is a slight problem with your custom intake port. If you think of fluid and air dynamics, both favor the path of least resistance (which would be your side port). The side port pictured is a medium/large street port. The extra rotor housing intake ports will just distort flow and kill air speed. A flow test you can do to see how the ports flow, take your water hose and spray the water in the port following the path of the lower intake runners. You will notice little to no water will be coming out of your rotor housing port. Water has the same flow charactoristics as air. IMHO I would either go with the standard street port or go with a peripheral port. One or the other. I would hate for you to waste your time, money and efforts on this project and it not work out.

Before anything, that exhaust sleeve needs to be replaced with the 13BT/rew rotor housing sleeve. Maybe you just haven't gotten to that .
