I am sorry guys if I didnt research much but I rather talk to the 20b GURU's for the info. Since a good friend of mine is selling me a 20btt Super cheap. I also would like to make 550-600hp on it also.

and if you guys did do it how much did it cost you.

Thank you for all the help

You'll need to at least act like you've gotten your feet wet searching before getting much help. Just being honest.

Since you have not indicated any automotive knowledge or resources, the going price for a professional 20B conversion is about $35,000 if the car is otherwise stock. Assuming your engine is in good shape, subtract about $4,000 from that amount. You will need to contact a shop to get a more accurate quote.

Asking others what they spent isn't such a great idea because you do not know what they started with or what kind of skills and resources they have. For example, if a professional mechanic with access to a full automotive and machine shop starts with a TII car that already has a standalone EMS, racing radiator, large intercooler, and a bunch of useful parts and materials sitting around, then the conversion could possibly cost no more than the engine itself. Not including the engine core, most people on this forum end up spending between $6,000 and $16,000 on the conversion if most or all of the labor is free. The nicer cars are in the $35,000 to $120,000 range.

If you are wondering why you received some comments from "haters" in your 2Gen Forum thread, it is because they are trying to tell you that this conversion is very expensive and/or for experienced mechanics only. They just want to keep you from making the mistake of buying the engine, stripping down your car, and then end up selling the parts for a huge loss on Ebay when you finally realize what you have got yourself into. Unfortunately, this happens quite often.

More answers to questions that you will probably have:
- If you don't understand why professional shops charge so much, then you have no business attempting the work yourself.
- No, you will not save a lot of money with an NA 20B conversion. In fact, a nice NA 20B will cost more than the stock 20B-REW and will have less power and twice the noise. An NA 20B is a great choice if that is what you really want, but it will not save a significant amount of money, if any.
- Yes, the stock TII drivetrain will handle the torque as long as you do not drag race with slicks.
- I recommend starting out with the stock turbos if they are in good shape. Pettit made 550bhp with reworked stock turbos and a street ported engine, and most rotary shops should be able to at least get into the 400's with the stock twins. Upgrading to a large single turbo will cost about $10,000 extra for a quality setup, and will add to the complexity of the conversion.
- A GT37R is too small for a street ported 20B. The rotary performance shop that you choose for the 20B conversion can help you choose a proper turbo for your desired performance and budget.

Hehe, $75k

By the way I did some work but the big stuff was done by professionals. This has been a 3 year project. I should have it this summer. It also took 6 years to buy the car. This is about the stupidest thing I could of done with my money. It is funny how over a three year period things in your life change...now sometimes I don't even know why I have this car. Which I am sure when I finally get it from Defined Autoworks I will rekindle my love but damn what a colossal waste of money.

Buy a Z06 and be done...

She sure is pretty though..

Damn dude that's alot of $$$$$ in that car? I predicting just over $10k for everything in my 90T2 20B 76mm turbo. I haven't started on it yet but I'm aiming to get it done in 1 month. I did the porting lastnight just waiting on the apex seals to come so I can start on the rebuild. Your T2 looks flawless.

Christopher W.

iTrader: (2)

Thanks....good luck with your build.

By the way, it is a GTUs

jamespond24

iTrader: (13)

Damn that GTU makes my T2 look ulgy : That is by far the nicest FC I seen in stock form.

Christopher W.

iTrader: (2)

Sorry, for some reason I thought you were the original poster on this thread. But good luck anyway with whatever project you have going..

Not to be picky but mine is a GTUs...very different from a GTU...as you probably know.

Also, yes the body is basically stock except for the side mirrors but it has a full built suspension, custom rear end, 20B with high comp. rotors, semi pport, Electomotive TEC3R, six independent throttle bodies, super custom exhaust, blah, blah, blah.....

So, yes stock body but nothing else.

I feel like I have almost forgot about my car. I haven't seen it in over a year.

I am now just starting a new project: 1987 Toyota 4Runner with a Lexus 4.0 V8 1UZ-FE with a solid axle front swap....a 2012 Expedition Rig. I am not going as far as with the RX7 but it is getting completely redone and build...also might run it on propane.

What a disease this all is......

I spent about half as much on mine so far, and it looks about half as good as yours. I guess you really do get what you pay for, lol.

... or buy somebody else's colossal waste of money for cheap:

Yea, at the end of 2008, early 2009 there were so many awesome deals out there with people selling there toys. I was just not in a position to take advantage since I was well into my own project.

Not to get into the rotary vs LSX argument but I have seen some insane deals on some really nice 3rd gen conversion cars.

I don't think I would ever be able to sell my car because I just could not deal with the financial loss. It is a toy for life...

I can't believe George still hasn't sold that car!

Evil Aviator

Nobody realizes the money and time required to build a car to that level. Television shows and magazine articles rarely indicate the true cost of performance modifications and custom work, and hot rod owners are usually really bad at math and/or don't want their spouse to know the truth, lol.

Lol about cost! Hmm just last week I stated to talley up my own 20b NA expense. So far I'm sitting at the 10k range on parts and all related items. The engine itself was $4,500 and nearly 1/2 my expense. I've spent that much over a 6yr period and had to get very creative on the parts I wanted to buy to keep cost down. Teaching myself how to fabricate along the way has savedme **** loads of money. Dedication is a ****. With what I'm trying to do, there's no telling how much a shop would have charged for my swap. I don't even wanna think about.

Christopher W.

iTrader: (2)

No, you don't..

I am excited to see what you have done with your ride. I love the idea of the engine moved back but, believe it or not, I did have to say no to some things.

By the way your engine sounds great. I needed to hear that..

Speaking of tallying up cost. I really wasn't sure how much I had spent but had to total it up for insurance purposes. It was a shock!

Fuel System
The stock FC3S (turbo) fuel pump is not adequate to support a stock 20B engine. The stock 20B run 6 x 550cc/min fuel injectors, so you're looking at a 50% increase in fuel injector capacity compared to a stock FC3S fuel system. At the very least, you need an upgrade fuel pump; there are economically priced upgrade fuel pumps under $200 that can easily support 400hp from the 20B. The Bosch -044 upgrade fuel pump should be enough for 400 to 500hp at the wheels. If you are shooting for more power, larger fuel injectors and larger (or twin) fuel pump(s) are almost necessary.
[Bosch upgrade fuel pump - $200; SS -6AN lines and fittings - $500; SX FPR - $200; fuel filters - $100]

This doesnt explain alot and ive been searching forever..cause ive ordered almost everything to get my 20b to run stock...with the ability to run higher hp at a later date..

Ive been looking for the fuel flow:pressures" and such but cant seem to find them or the stock turbo pressure which i thought was between 10-14lbs but im stuck :P but so far now that ive been into this project and having work done by a shop "motor" was done by my bro and ive spent a good 12k so far...i hope if you do yours it turn out well and the engine still has great compression before you put it in or you might have to tally in 4k i think for a rebuild?
luckilly mine was good..also is there a place i can order the new front anti sway bar?

Uhm.. $75k? were you joking?


I can back this up. He is, without a doubt, telling you 110% truth.

Gordon lives! And also tells the truth. I'm one of those guys that spent way more than my original estimated number - search for my name and see my 4 year thread for proof. I am really happy (finally) with the way things turned out but it does take two things to make a 20B swap happen: 1) time and 2) money.

Yes, it will take a lot longer than you think, even if you do it yourself. Based on what I know know, plan on about one year at minimum to do the swap. Why? You need to custom fab up pretty much everything and that takes time, whether you do it or someone else is involved. And if someone else does it, they'll end up working on your car a little bit at a time as they get other cars in and out of their shop. Wish it wasn't this way but that's the reality of how it works.

And yes, it will cost much more than you think. I can recall the numerous threads that have popped up on this forum where the OP claimed the swap can be done for $10,000 or so but I can also tell you none of those guys have posted up success at that level. I'm one of those persons that has spent over $75K on the conversion. That's more than double my original estimate and it does include suspension and tire work, and yes, it's a crazy amount, but it is reality. A lot of what I spent was on having bad work redone so I would now think you can do the engine side of the work for about $35K and then the rest for around $15K for a well sorted out 20B. But this take knowledge and also knowing where to send your car. PM me if you are contemplating going this route and I'll let you know who I think is capable of pulling off the conversion without screwing you. The list is short.

Well, that's my learned but opinionated 2 cents on the matter

iTrader: (2)

Yea, sure I am joking....

I wanted my dream FC and I can't build it myself but I can pay people. Although I have done a lot of the work in certain areas. My rotary love is with the FC. I an not interested in FDs. If I had one it would have an LSX.

Yesterday I pulled up in traffic next to a new red GTR. I had no visceral response. I really did nothing for me. I am not saying I would feel the same after driving but.. My car sparks something primal inside of me. Not to sound to silly. Hell, I haven't even driven it in three years. Just think how good it will feel when I can drive it. Hurry up Logan, I am ready.

Value is a perceived quantity. Any good salesman knows that.

On the one hand, thanks for pointing him my way. OTOH, "colossal waste of money" is both unkind and untrue. In terms of bang-for-the-buck, my 20B-powered car is the best deal going. I could not have bought a car with the combination of power and finesse for what I put into the RXX-7. I have never regretted doing the conversion. If I don't sell it, I'll just have to endure having a car that is competitive with vehicles costing almost five times as much (or more - see my post: A reason to feel smug).

https://www.rx7club.com/20b-forum-95/reason-feel-smug-886208/

And this is a daily-driver!

With that said, "for cheap" is absolutely true.

Christopher W.

iTrader: (2)

Yea, I used the term in my post, "colossal waste of money," as sort of a self-deprecating term. I myself really don't feel that way.

But to see that number and know how much money I make in a year, it is shocking. That is one of the benefits to being 46 yrs old with no kids. I am not saving for someone college, braces, shoes, none of it. Although that might not be all together true in the next couple of years...

I could not buy a car for that amount that fills this desire. It goes beyond the final product. Although my final product is going to be incredible. It is the fulfilling of decades of car dreams and years and years of rotary dreams.

For me to go and buy someone else's car and then try to make it mine would not have done it for me. I doesn't matter to me that I haven't done all of the work. This is still my vision fulfilled.

Yea I'm really big on improving the factory CG and balance. My project keeps getting extended because I'm now doing doing extra stuff unrelated to the engine swap. Example! I bought some new wheels this past year and am now doing my own body work with molded Pettit Flares. Molding the flares wasn't nearly as hard as I thought it would be. I'm also doing my custom sleek light set-up w/projector Xenons. LOL my co-worker tells me I keep putting money into a car and don't drive it. Oh well I guess my car is in it's metamorphisis stages and hasn't shed it's new skin yet. It's new heart beat should be much stronger as well.
