How much would this cost?!!

Hi,
If I were to convert my 1993 FD into a v-8 using the LS1 engine, how much should I expect everything to cost? (including labor). Thanks in advance.

would cost you a arm and a leg prob around like 6k

why would you want to convert in the first place? 1.3 liters, 255 hp, FR, etc. plus the engine is one of a kind.. it could kill any v8 any day. :flipa: :p

Its been done. And is not generally accepted among rotary fans ;)

If you're gonna spend the money anyway, just get a 3 rotor 20b engine and mod the f*** out of that! That way, you'll still be kicking ass, and it'll stay a rotary.

but if your dead set on a pisst-on engine, then check out granny's speed shop.





rotor>piston

If you dont already have a mullet, you should start growing one to go with the v-8...

An LS1 engine has no chance against a modified rotor.

As for the price, expect to pay way too goddamn much. For the amount of money you'd put into the swap, you could have that rotary putting damn near 550 HP to the ground, if not more. And I guarantee that'd be enough to completely slaughter any LS1 you'd be able to drop in. Besides, that big V8 weighs about three times as much as the 13B, which would totally kill the handling of your car. It'd handle just like every other car with an LS1: complete shit. As for the labour, there would be a lot of it involved, and you're looking at something more like 10 large for the whole thing. I'd say screw it and tune the rotary.

Actaully the v8 doesn't affect the handling of the car that much. It get's better if anything, when you balance it right. A v8 weighs about 70-100 pounds more than a 13bt.

I still find this better handling quote amazing? How can it be better? 13B is lighter, mounted lower and further back on the axle, how could u get better?
And dont just say get new springs and stuff, coz u can always do that with the 13B still in place.
If u want an LS1, buy a barge with one in it. If u want a sportscar, keep the rotor.

Nope, its true. a 13b turbo is not really that much lighter. A guy on the 7 boards converted his vert to an LT1 or LS1 (cant remember) but he said the handling and weight was fine. And now he has a FAST vert.

it could possibly be similar handling, but def not better. Weight isnt everything, is also centre of gravity.

there is a dude on another forum he sellin his 1987 rx7 with a ls1 swap and turbo 500hp for 6000$

dude, you know nothing about rotarys... you just read that off a magazine, and now act like you know more than everyone else.

yea i read the same article but i think its kinda silly to try and classify a rotory by reciprocating engine standards. the guy says that since its not a 2 stroke piston engine you have to count two of its combustion cycles as one :rolleyes: oookkkayyy

P.S. a V8 in an RX7? thats blasphemy! go with a 20B, or better yet find a 26B 4 rotor :devil: if it would fit

Even if you were not to count it as 1.3, you multiply by 1.8 not 2, making it a 2.3 engine.



But the fact of the matter is, the SAE as well as Mazda says its a 1.3 litre engine, so its 1.3. Deal with it.

On a different note, I heard somewhere that if the RX-8 is popular enough, mazda is gonna make a fourth gen RX-7 with a 1.4 turbo engine. Saweeeeeeeeeeeet.

they had a pic of the 2006 rx-7 in this months popular mechanic's... it was kinda ugly I thought compared to 3rd gens. Here's a pic I found...

i hate to say it but i miss the RX7 :( , if they could have just updated the chassis and used a side port rotory with a turbo it would kill

Well to me, how you stated "everyone thinks..." is saying you know more than they do. "Perception is 95% of the truth".

They could of, but sales were shit so Ford pulled the plug.

hope fully the RENESIS will prove to be durable then maby we'll get another turbocharged one (i hope), the torque could use some help
:bonghitte

I cannot believe it. You guys read Dave Coleman's article about the rotary engine displacement arguement, then start talking about hope for a turbo....

It is not going to happen on the Renesis...

Face it, No Turbo(s).

Maybe a small supercharger

Concerning the torque issue. If you read on through Mr. Coleman's article he talks about his theory of a "16B" rotary.. outlining the fact that increased displacment will increase torque and horsepower.

That is far closer to what "may" happen with the "new" RX-7 on this "new" platform.

Bumping up the natural displacement is just as easy and changing a few numbers on few drawing of the engine.... To pressure charge this engine...properly.... Ports will need to be changed... (atleast alot more than if you just make the rotors wider) moved, reshaped etc.....

I think some people are under-estimating the Renesis by what they read about a pre-production bug-riddled design engineering model. Wait until they hit the streets. Change the exhaust, open up the intake system...
and 300 hp on tap...

then you have the nut that yanks out the engine, ports it (equivilant of changing cams in a piston engine). re-maps the intake valves to become active sooner, more reactive.... Re-maps the fuel map(s) etc etc

Sorry for the long post... But i can still go on and on,,,

yes i did read the article, and it all sound well enough but i dont think id be satisfied with an NA rotory, 300hp and what a whopping 180 lb-ft? if all the roads where straight... but i guess i shouldnt bitch theirs always aftermarket turbos. and dont take this the wrong way i really do like the RX-8 :)
