I have been thinking about this swap, the engine is about the same size as the fa20 but has 200-250 more bhp and a 10,000 rpm redline and only weighs 200 lbs stock

when i get around to buying a used/crashed frs/brz i would be doing the swap and stripping the car for track duty

and replacing the stock final drive with a 5:1 raito

any thoughts?

also i was wondering(yes i did a search and maybe i didnt use the right key words) but what is the dry weight of the FA20?

Pretty aggressive. It's a great platform, keep us posted!

Edit: do you have one of these engines in your possession or experience with them? Are they legit / price?

Are you an existing customer?

"As of March 2012, the H1 and H2 engine technology has been sold. The new owner will further develop the technology for race applications and plans to offer it to other markets later this year. Hartley Enterprises retains the rights to build these engines in limited numbers for select existing customers and special projects in the US."

the idea was thrown up in the air, the engine comes ready-to-race, they go for around 12k-18k(edit:used) depending on what you want in the engine, they are well built and ive never heard of problems resulting in build quality from them, i love to rev, i love hp, but i also love na, and this is a nice little package, with the right final drive and with this car being light enough, also with the manual and automatic transmissions holding up to over 300+ tq from accelerated prefomance's turbo build, small modification to the transmission bell housing and it should bolt up just fine, i do want to retain the butter smooth shifting in the manual, if the build can be done without buying a new transmission, that would be great... all my option are open, we will come to one solution if we decide to go down this route, i will let further development and R&D progress before i attempt the build

still deciding if i want to go auto or manual with this engine aswell

i think you can get a brand new H1 for 30k or something like that, but you pretty much just check valve tolerances and change the oil and thats all you do to maintain them...

EDIT: they also have a 4.0L v10 with 600hp under development, that will weigh as much as a standard 2.4L car engine, forgot the source, i found some info on it when i was researching the engine....

Is that the engine made by putting two Hayabusa engines together? Those things are nuts!!

That would be awesome - 400 bhp NA in a BRZ/FRS. Too pricey for me, but if you are building an all out race/performance car that seems like it would be a very potent package with a little lightening of our platform and that engine.

I need to get my hands on one of these engines.

Cool engine but I don't know if I'd ever put one in a FR-S/BRZ. I'd put it in a Super 7 or some other tube frame kit car.

^This. It's a neat idea but that engine would be a complete waste in something as heavy as the BRZ/ FRS. You need something below 2,000 lbs for an engine like that.

Yeah peak torque at 7500rpm is a huge turn off for me. I think it would be cool to strip down a scion iq and put that motor on the back though.

If i had money to burn...

I have a 93 miata shell in my backyard :(

This would work wonders for a drift car

Very interested in this project if you start it. Subscribed! :thumbsup:

Not cheap. You'd be better off with an LSx.
