I think that will look real good in my engine bay.

I dont think it will be too hard to swap in i have the no how and the skill to make everything but i may need some ideas.

Fuel is easy to make happen( thank you mazda for inline fuel pump)

Engine mounts are simple to make once i get the position figured out.

Exhaust will be easy but not fun.

Computer is easy but ill have to make a custom dash.

Tranny mount is agian easy but will take positioning

????If there is anything im not thinking of but you guys are let me know.?????

I am planing on doing the full write up and pics of everything i make and things that i buy. So if this swap goes well others can follow it.

i sure hope your going to put that in a civic......

Your forgetting the rotary.

as many rotaries as he has gone through, i dont blame him... i was going to do this when mine give out.. but i hope you plan on doing a custom ITB because the kit is like 2k with a reflashed ecu, and like 3k with a tuned standalone. but with a custom manifold, megasquirt and motorcycle itb's you should be able to pull it off...let me know how it goes, maybe then you can help me with mine when i do it... but when you buy a 1.8l motor, dont get the 91 year engine, it had a short nose crank that was prone to breaking.

what 1.8 are you using? honda B18? miata? if youre using a honda, what tranny are you using? what are you building this car for?

ive seen a fast as B18 powered hatch at my local strip consistantly run 10s and break into the 9s. it was a guys DD also.

i was assuming the miata...

That is a miata engine.

correct its a Mazda Engine.

I picked up the engine today and it has 56,000 on it and i got it for 100$

A used 5sp runs about 150$

and i have to find an ecu and most of the stock sensors and fuel system, no point in spending all that money if i cant get a stock one to work first.

are you going to modify the stock FB gas tank and make the feed line bigger?

Im not going to use the stock fuel tank Im building a new one.

But it would not be hard to do ill make sure i include how to change the fuel delivery in my write up.

whats the update?

no boost=fail

all that work for what, 160bhp?

K I was thinking about that the whole time. Like the above statement. But I wasn't sure if these were suppose to be an engine with alot of potential or what, but I mean even a stock 350 or even a stock 302 would be better then that man. But wouldn't mind seeing pictures of though

Wow thats a great price!! :) I got the "hookup" on an engine for my miata and it cost $550 and it had around 70k on it.

The problem is when you toss a small block cast iron into a FB it throws the hole turning dynamics of the car off.

I wanted something light and that could put out if "i spent the money" around 300 hp.

sounds like a fun project, let me know if you need a tranny as I have an extra.

honestly man I am not tryin to convince you go sell that and buy a v8 but the whole "weight ratio" "it being ALOT heavier then a rotary" and "will fubar your turning" isn't true man. Perfect example is my buddy has a FB with a 355 in it and he uses it in both drag racing and in road racing and in road racing he has one of the best overall vehicles out there. And I have driven it also and it takes corners pretty nice I must say. But again please dont get all bent outta shape thingy that I am trying to say my way is better or anything like that. I am just stating my opinion on it from first hand experience thats all.

Project scrubbed for this year look forr an update this spring.

some people like revy little engines. any word on using rx7 transmissions? I know that they are close to miata transmissions but I have never heard of anyway you could bolt a BP engine to any RX7 transmission. does anyone know?

They have adapter plates out there for any tranny mating. I know Miata guys have used rx7 tranny in the miata.

You can boost about 12 psi easy on that b18. I did 18psi on my b16. You will get about 275 rwhp in doing so.

It is a fun motor to play with and easy to replace... 5 years ago i got a replacement for 400 bucks and parted out what i did not need (actual cost at the end 150-200.oo).

I recommend using the miata tranny w/ your rear. The gears are tight the miata so the low output isnt so bad.... and the rear is a 430 if i recall. The 7-tranny w/ a rx7 rear... too long in my opinion.

After getting the BP in there why not jump in and swap on a FM Turbo kit? Outside of being OEM reliable it is also a seriously well detailed conversion for the BP 1.8L.

Look up Kieth at Flying Miata for more info on the kits available.

I should really finish this project before i start the Mach 5.
But i think a movie care is better then miata'd 7
