Besides kiwi-re who sells a complete kit to use existing 13b/12a parts for a 3 rotor?

How much are they?

Is it cheaper to just buy a 20b?

Trying to give myself a headache doing research for the best and COOLEST option i can think of for a motor next year if i scrap my 2 rotor......

 

Sorry... not cheaper

 

It is way cheaper to just buy a 20B.

 

So an off the shelf kit itself cost more than a "turnkey" low mileage imported swap?

Yowza!

 

Pulse Performance in NZ sell race parts but they are NOT cheap. They are however, totaly top quallity.

You can get a used JDM 20B for 3,800.

 

He's right. I've seen them sell as low as $2,900;
You would cringe at the price they sell for in Japan. Anyhow, I'd stick to buying them on eBay or call Nippon Motors (in CA). They typically have them ready to go @ $3,500;

 

Yep I got mine for $3k shipped and it's a C code.

 

only use the kit if you are going to build a PP motor, otherwise 20b is the only way to do it.

 

Thanks for the help! Definitely makes things alot more clear!

If that's the case, i'm wondering if i can shave a buttload of overhead cost off by requesting motor only, no trans and no twins (turbos). Time to pm japan2la!

 

He doesn't sell them that cheap, you'll have to look elsewhere.

 

I now know this. Lol.


But the extra money is going towards peace of mind.... That's why he has the rep he does. He doesn't bullshit around a lie about mileage/compression/engine specs.


Alot of importers assume you're going to blow the thing up on startup. No warranty, Just tears. They dont bother to check anything. "yeah, this looks good. Throw it on a pallet and sell it."

 

You can stop wondering. The answer is no, you can't.

Doh!: 1 minute too late. . . sorry for the now worthless(er) post

 

Hey now, you just said a "a lot of importers.." please bring proof of that before spouting that type of info. You are scaring business away by making statements like that.

now back on topic.. I'm not sure there are many guys who buy 20B engines and install them without an overhaul so in that case I dont know where the extra $1k piece of mind sits.

Anyhow, I think we all agree it's a lot cheaper to buy a working 3rotor vs. a kit for 13B engines.

 

Wow! Those prices are horrendous! The exact same 3 rotor kit can be bought elsewhere for half that price, and the 4 rotor kit for a third less.

 

He's reselling a known kit. I know very well how much that kit costs and this guy Ramy'ed up the price a good deal. Maybe because it's JDM tyte? :-)

 

Keep in mind those are full built race motors and in NZ dollars. Not just a stock 20B copy. He does all the porting by hand, all the mods to the oil galeries/stationary gears etc in house. The E shafts are custom made to his spec I believe (dont quote me on that). I dont think these are a kit from anywhere that hes on selling?? Mad mikes 4 rotor makes over 500whp NA on their dyno and that dyno is known to read a little low compared to others. And that motor is STILL in the car and hasnt been opened up once since built from what I was told. Thats like 4-5 years of drifting on the same motor.

 

Yep. It's worth the arm and a leg.






hwnd, i didn't say the "majority of" i said "a lot".

I also didn't drop any names.

It's not nearly as bad/scary out there than it was 8 years ago.

Freakin start up warranty only on b series honda engines. Front clips were cheaper to ship then and were worth it if the engine didn't work or not. 8 years ago, an rhd conversion was actually cool.

 

It's Jeff Bruce's kit.

 

Just out of curiosity, what parts are from the kit?

 

Here's the list from green brothers racing, Aka jeff bruce or richard.

I'll give you their email only if your serious,don't want you bugging them with stupid questions

P.S keep in mind those are priced in NZ$ use exchange rate calculator before going ape **** about the price,,You cheap bastards
