Hey guys I am sorry if this is being created in the wrong place. Didnt know where else to put it.

I am doing a swap on a rx8 and i want a 13b rew to go in the car. I found a website called tigerjapaneseautoparts.com they sell the engines

I was wondering if anyone here know if this people are legit

With a custom swap of this magnitude there are many things to consider. A JDM engine and tranny could be a viable option for getting the initial core components for the swap. As many people have said, a JDM engine is a gamble. It may have good compression, it may be garbage with nothing even salvageable for a rebuild. Furthermore, the tranny has the same possibility. With this, you have a few options.

1. Buy a Jspec engine, asses the damage, and have it rebuilt.

2. Lurk the Marketplace for a full setup for sale. They do come along from time to time. There are often engine partouts and folks going LSX. With the amount of other modifications, planning, and auxiliary parts to research for this swap, it is a viable option to bide your time with cash on hand.

 

RX8/13 BREW........... good idea

"1. Buy a Jspec engine, asses the damage, and have it rebuilt."

bad idea, or more accurately stated, highly speculative idea

"2. Lurk the Marketplace for a full setup for sale. They do come along from time to time. There are often engine partouts and folks going LSX.

good idea


good luck,

Thank you for the link. I will look for something local

 

That is my plan buy it and rebuild it. Do it right the first time

 

Prepare spend at least $10k

 

I am not looking to upgrade the engine at all. Its going in stock. I already did the math for parts including the engine and im looking at 4500 plus misc stuff and labor which i will do most of it.

 

Good luck

 

you are in miami there are local importers for REW's talk to them and you can check the compression yourself before you buy it

 

Like he said $10k to have it all working right.

I've never heard of ANY engine swap costing $4500, turn-key

 

Its not going to fit stock. The twins don't fit. You have to going single turbo which means the whole shabang. It's not happening for $4.5k. You'll spend more then that in parts alone. 10k is an ok estimate, but the reality is you'll probably have spent more on it when when its actually "perfect" if it ever gets there based on your ideas that its a drop-in affair. On the plus side, you can buy engine mount adapters for the swap... But again, it won't fit until twins are removed.

Me neither. 4500 plus in parts is what i said/meant

 

Thanks for the info didn't know that of course.

Thats the mount I am buying.

 

Psh, obviously you haven't swapped a B18 into a Honda Civic hatchback

 

The mechanic told me i need a custom manifold to make the engine single turbo. Is this true? Or is he just trying to make more money out of me? Ive seen different builds on the internet and they are using the stock manifold

 

As we've been telling you, this is not an easy swap. He is not lying. You need A LOT of custom work done on the car. There is a reason we're telling you its going to cost 10k by the time your done. You can't do it with the stock manifold.

I have bought an engine from JDMTigerJapanese before for my friends 92 skyline, price was cheaper than other places we look and the engine came shipped to our door for like $900 the engine was complete and had very little visible damage from being shipped. we only used the head off the engine and kept rest for spares but we were pretty pleased with the company. I may use that company again for my rew swap.

 

You need an exhaust manifold that will bolt up a single turbo to the exhaust ports. The stock manifold is designed for the stock twins. To get an idea, take a look at this kit:

Garrett GT35R Turbo Kit

That kit has the basics to for installing a single turbo onto the 13B-REW. Granted, that's only the turbo; there is still the fuel system and management to deal with as well.

TBH, I'm not entirely sure why the 13B-REW swap would be a good thing. The engine parts are becoming more hard to obtain and expensive. Doesn't really seem to be the smart thing to do...

 

Turbo'ing the RX-8 motor is a bad idea. They don't last. Going REW is the only reliable option that fits easy since theres a mount adapter for it.

Being a local to Tiger, 80-90% of their rotary motors are blown and the rest have coolant seal failure within a year or two. They buy their parts at the scrap yards in Japan. If you buy a motor, expect to rebuild it and replace the hard parts. The only thing I would risk buying from Tiger are FD transmissions, I've never had a bad one.

And that is a cheap kit too. The good ones are over $3k. Also, this won't work for him, he would have to build one custom to fit the RX-8 chassis.

I got a second opinion today. The guy has done 4 swaps already so he told me i need the throttle body from my 8 to mount it on the fd engine some custom work has be made. He recommended getting t2 turbo and manifold. He said it is easier to do it that way. Microtech lt10, custom engine mount, rebuild, labor plus misc parts. Grand total is close to 8000. The engine will be 100% stock with rx8 drivetrain

 

Your numbers are making more sense now. Your car won't run that great on the Microtech though. Spend the extra and put a Haltech or an Adaptronic in there. Turblown can get you an Adaptronic, give him a call and he can tell you all about its features.

Also, keep in mind a Tiger motor is an almost guaranteed bad motor so add rebuild cost if you go that route.

And, is tuning and dyno time included in that quote . What about rad upgrade, intercooler, BOV, custom piping, fuel pump etc?

thewird

 

Is microtech a poor standalone? Or just when compared to the other two mentioned?

 

Microtech is good because its cheap and easy to tune. However, the simplicity of it is what makes it an inferior ECU. Idle and drivability will never be perfect. It also lacks a lot of features.

I don't necessarily agree there. I've known several guys to turbo and track RX8's. Yes, they aren't going to last as long as a NA, but I can say they lasted a heck of a lot longer than most RX7's I've seen at the track. Granted, the RX8's weren't cranking the boost up like most RX7 owners either... When done 'properly' there really shouldn't be much difference as far as longevity. The question is are the RX8 owners "doing it properly". My guess, their culture is much like the RX7 culture was at the same time, still discovering what not to do.
