20b engine swap?

Alright to start of I am kind of a noob when it comes to rotary engines, I just recently made this account and got interested in the rx7 and tuning it. But i will do my research dont worry, but can you guys just answer my questions?

Alright so with 22k I want to swap a 20b engine in a rx7, how much would the engine cost, how much would the labor cost? Where can i buy a 20b rotary engine? I found one online for 7.5k at http://www.rx7store.net/product_p/20b%20engine.htm

Is this a good one? Please list me all the websites you know where I could get a good 20b for under 10k if possible, and how much would the labor cost? 1k?2k?3k? I have no idea .

Alright so now with the remaining of my cash (Lets say i have 10k left) I would like to slap on twin turbo's or a single turbo. Where can i get some good twin's or single turbos online, i would like over 500 bhp with the 20b engine and the turbo, and for it to be possible to reach 100 kph in around 4 seconds, is this possible?

And now for my last question. Ok im sorry buy i seriously hate the single huge exhaust`s people use on tuner`s please dont give me hate, its just my opinion I do not like it, but every single tuner car has that. So what I want to know is, would two exhausts like this 300zx has, http://www.dragtimes.com/1991-Nissan...ures-9372.html

If i had two exhausts like that on a veilside rx7, would I look like an idiot? I never seen an rx7 with two exhausts, if you have please send me a link!

But yeah would I look like an idiot if say i brought a veilside rx7, but with two exhausts to an auto show would i look stupid?

Thanks

For $19,900, you can buy a turn-key car:

...and it already has dual exhausts!

$22K is not going to get a 500hp 20B installed and running, for that matter it does not cover the cost of all the parts, even if you do all the work yourself. You might want to look through our 20B gallery and take a few minute to add up some of the component costs.

What if I can prove you wrong? If somebody willing to give me $20k and their car I guarantee they get a 600rwhp+ 20B. Anyone want to take a chance?

How about you just do it and prove me wrong on your own dime? That way when you get halfway through the project and run out of money you have not scammed anyone.

I know exactly what it takes to build a reliable 600+rwhp 20B, I have one. It can not be done for $20K.

i agree with Banzai Racing here.. it's going to take a lot of more than 20k to build a reliable 20B FD

Could you give a ball-park figure for a reliable 600 Rwhp 20b? I know the parts and prices can vary widely, but it is sort of confusing to even get ballpark figures reading the FAQ etc. I priced out some race-ready LS7's from Katech and others that would put down low 500's rwhp fully dressed would be around $25k.

If a long term reliable 550-600 Rwhp 20b could be had for $25-$30k I would definitely be interested. If it is even more money than that I couldn't see the justification versus an LS7 for my project car.

I'll have to disagree myself with this comment. I don't think IronMdx spend any where near that amount in his 1st attempt (before he wrecked it of course). He did everything himself. Also parts will only be that expensive if you purchase retail from venders. There's ways to build a quality set-up without paying soo much for parts.

You are right anyone can cut corners and/or buy used parts, we will not do it. We have no idea what the total cost of someone else's build is, neither do you, so it does not make much sense to comment on it.

Facts are the parts add up quick, let's do a quick tally shall we? I will use our costs which are a little less than others:

20B Engine $4000.00
Rebuild (insane not to) $2500.00
Street Porting w/FD sleeves $750.00

This is $7250 for basic SP rebuild engine assuming every hard part was good and no rotors, housings etc needed replacing in the used 20B core. It would be a little less if you did the rebuild yourself, most people will not. This does not include any dowel pinning, studding, etc.

SP Engine $7250.00
Subframe w/bumpsteer $1500.00
Exedy Twin Disc Clutch $1600.00
ECU $1500 (we just use a Microtech for this pricing, otherwise it could be much higher and this exercise would be over already)
Custom FMIC & piping $2000
Dual 25 row Oil Coolers $1200
Custom Radiator $500
Fuel System $2000
Ignition System $1000

Quick total for just those $18,550, not one of these items has been shipped yet, which of course cost considerable money when you are talking about getting an engine shipped to you, then to a builder, then back to you. That will eat up $1200 and nothing else has been shipped.

$20K is officially exceeded + another $500 at a min in shipping.

So now you still do not have
Turbo System this can go upward of $5000 quick to support $600+hp
MP+Catback upward of $1200-$1500 (my Apexi PS revo is $1000 alone)
Differential, (stock will self destruct) $1000-$1200
Water/meth injection $350-$1000

There is another $8700. These are just the big parts, all the small components add up quick also. Belts, hoses, vacuum lines, block off plates, custom brackets, throttle cable, pulleys etc etc, there is another $1000 minimum

That is over $30K in parts that are not installed yet on the car.

Not required for a 20B engine to run , but for reliability & safety, these are low ballpark numbers:
Brakes $1000
Suspension & bushings $3000
Wheels & tires Minimum of $2000 (my tires alone are $1500)
Driveshaft $500
Chromoly axles $500
Instrumentation $500-$2000 (I have all Defi)

The list goes on. That was just what I thought of quickly off the top of my head.

That too, the transmission at minimum should be rebuilt. Mine is freshly rebuilt and is currently holding up to 621whp/482tq , but I am not expecting it to last forever. I have 3 spares.

So add a $1000 minimum for a trans rebuild to the list above. Now for the people that want the T56 conversion add $4K-$5K (guesstimate, I haven't really looked into it)

There are bunch more parts, but since the $20K was exceeded prior to even selecting a turbo, I figured why kick a dead horse.

Roll bars and chassis bracing
Heat shields, wraps and turbo blankets
Drycell battery and relocation
Boost controller
ETC..................

Thank's for the realistic cost breakdown. Does Banzai do all of the engine build stuff in house? What about the turbo part of it? Do you physically need the FD chassis there at your shop or is that stuff like the turbo routing pretty much already built to standard specs?

Can't speak for Banzai, but I can tell you from my own personal experience, that the DP should be custom fabricated on the car for best fitment, so you should either ship the car to them and have them do the work or be prepared to do some of these final steps yourself for best results.

Yes we do all the engine porting/building/installation in house.

As with any custom engine installation, there are far too many variables to play with for us to offer a standard turbo kit. Each one is custom made for each application. For example, there are a couple different mounting methods/subframes on the market each of those place the engine in a slightly different position. This changes the routing of the manifold and DP.

For retail parts purchases your prices are right on the money. Let me show you what a resourceful DIYer can do. Also buying pre-fabricated parts are going to have to be avoided to save money. Orginally you said 500 hp so the list below supports this!


"D" Series Engine $4,500.00
Porting not needed
3 junk housings for sleeves $70.00
Rebuild parts $700.00
Metal for subframe $20.00
Exhaust tubing $150.00
Racing Beat Flange $50.00
Magnaflow Muffler 4" $120.00
Exhaust Tip $60.00
Aluminum 2 row radiator $110.00 Mine is larger than the expensive Koyos.
Twin Oil Coolers $350.00 I'm running a 2nd gen since I'm NA! Way larger capacity
IC with piping $400.00
Haltech w/harness $1100.00 Bought new 2nd hand.
LS2 truck coils w/harness $250.00
Build plug wires $60.00
Fuel system $1500.00
Turbo and wastgate $2500.00
Stage 3 clutch $500.00
Flywheel $200.00
T56 tranny $3000.00
Axels $700.00

That's $16,340.00 but lets make it an even $17,000 for misc stuff.

Now this is an extreme case because you have to fab everything but, it's easily achievable because most of this is my own expense (minus turbo stuff of course). Also everything above is new.


Now how reliable with this set-up be? That's all dependant on the quality of the fabrication and most importantly the tuning.

I done 2 20B swap that make 600+rwhp for less than $20k and that's including the shell. If 10 years ago I would agree with you not now. Yes both car are RUNNING too.
