V-8 Fc
 

Getting 1988 turbo 2, I was wondering which v-8 engine I should put in ?
Right now I am almost positive on a 350 sbc but a 302 swap is very possible. My only requirements for either or is EFI. Which ever engine I pick will quickly be recieving two T04E .50ar turbos and a new tremmec. Any suggestions?

Hey welcome, im afraid your questions wont be well recieved.
Theres several choices out there for other forums better suited to asnwer your questions.

Why not put another rotary motor in it?

no. im sorry.

Its not you, its just your idea. Adding a V8 to the seven is such a waste, I mean you buy a seven becuase of the rotary, not becuase of really how it looks, there are plenty of other cars that look like the seven that use pistons.

If I were you, i'd search to see, there are a few people here who have and are putting V8's into their sevens.. just search and you'll find out.

can we leave the war out of this one please? the guy's just looking for answers.. it *just* a car..

He can get the answers by searching buddy. Do you walk into a church and ask where you can find a book on satanism? NO becuase its gonna start shit.

lol, im sure if he searches he'll find out what the other members are using.

Very well put. I agree completely.

if only mazda would hear about you putting a v-8 in a rotary powered car, u would get bitch slapped a million times.

check out the Other engine conversion section.

heh.. the owner would probably bow his head in shame, come up to the guy and give him a tanto so that he can end his own life.

I am just looking for a cheap reliable high power source for a car that out handles most. Not that I have anything against rotaries I just think beating the hell out of a good old v-8 and being able to do again without working on the engine for 2 hours would be fun. Besides I have a rotary project up my sleeve.

it would be alot easier for him to jut get a 3rd rotor..than to get a V-8... or just get a fuckin ford prob and put a V-8 in it... like the 93 model...

It's easier, cheaper, and makes more sense to put in an LS1/T56 combination in an RX7 than it does to drop in a 20B. It's been covered a million times. The only reason you drop a 20B into an RX7 is so that you can get decent torque but still have a rotary engine.

Mandilater - the LS1/T56 is pretty much just the right combination for the RX7. You're geared perfectly for all types of driving and you get an engine that can make 400+rwhp to the ground N/A, easily. The 302 is lighter but the combination of the T5 and the 4.1 rear end make for an engine that redlines at like 5500 and is cruising down the highway at 3k.

Thats the link to Granny's speed shop where you can get more info about putting a motor in a RX..

NOW THEN... I don't know what you're planning on doing with those turbos... but if you get them to fit in the engine bay of a TII along with a v-8 motor, you should get together with Stephen Hawking cause your some kind of genious!!! Take a look at some rx-7 V-8 conversions... there aint no room!!!!

i know for a fact that the Ford Swap is easier on a first gen.. second gens, i don't think it matters and the kits are cheaper for the chevy (however, MAZDA is owned by Ford... you may want to stick with the program a little bit!!!)

Yeah a TT LS1 isn't going to happen. I've seen a TT LT1 but it was in an FD. A vortech intercooled supercharger kit would fit under the hood, but you'd have to do some custom work with the intake piping. Personally I'd build a heads/cam/nitrous LS1 or if you don't mind a hood scoop, install a magnacharger.

I think you could do a twin turbo 302, but then again that would be a TON of work.

www.grannysspeedshop.com and www.hinsonsupercars.com both sell V8 mounting kits and www.torquecentral.com is the site to go to for any questions on a V8 conversion.

putting the 350 v8 up front will negitively effect the handling,by throwing off the good weight ratio. and probably raise the center of gravity also . which wont make this car handle that great anymore.

another thing to look at about putting a v8 in is the REAR END gear ratio. the stock rear end is a 4.10, which in alot fo 350 trany conversions is gonna lower ur top speed drasticly and make highway cruizing rpm quite high for a v8.

are you just guessing?
-the weight chnge is minimal, like 3% change in real world moment of inertia for the chassis, that is nothing you would feel unless youre in a speedvision roadracing competition.
-the 4.10 rear end is great for the LS1T56, in fact lot of F-body guys throw in a 4.10 when they start modifying their shitty camaros/firebirds (lol)

the misinformtion you guys spit out is sometimes ridiculous and usually not fair to the wonderful FC chassis that Mazda designed so well. Us v8'ers love the FC chassis, its incredible, but the rotary is less than desirable, especially in the sorry state of disrepair that most FC's seem to be in.

^^^^^^^ Agreed...

In our Regional Road Racing series here in Ontario there was a 302 2nd gen that was a beast. Handled great, both hp and torque. In the two or three seasons it competed it had a number of podium finishes.

2nd and 3rd gen LT1/LS1 conversions. *See the FAQ's

Holy shit there are some stupid people on this planet. Can't anyone just answer the damn question without being a dick? (no offense to the couple guys who DID provide useful info)

You can fit 2 turbos into anything with any motor if you really want to. All it takes is a deep pocket with a fat wallet in it. It won't be easy, but hey if you have a rotary project, you know all about that.

For lightest weight, the LS1 (or an aluminum block/head standard SBC engine) is the way to go. LS1's are the latest design available from GM with the best hp/tq numbers yet and great gas mileage to boot (stock Vettes = 30mpg on the hwy).

For the cheapest route, the standard iron SBC engine is the most common engine on the planet. You can get a stock used junkyard 350 for $50-100. Of course, the more power you want, the more it will cost. It's all up to you.

For the smallest package, the Ford 302 is a nice fit and though it is not in fact lighter than an LS1, it's lighter than a lot of V8's.

My recommendation is if you want to run 2 turbos, go with a Buick V6 from a Grand National. I know of one personally who is running 7 second 1/4 mile times with his single turbo motor in his Grand National (yes it's a race car, but the point is it CAN MAKE POWER). It's basically a V8 minus 2 cylinders as far as dimensions go, and the aftermarket for that motor is astounding. It will still be a tight fit, but that much easier with the smaller block.

No matter what you do, don't pay attention to the idiots who think you bought a car because of the stock rotary engine. Maybe some people do, and hooray for them. I buy cars because I like the cars for their potential and positive points. When I build an airplane or a rodracer I will gladly use a rotary. Until then, my RX7's will have RELIABLE, USER FRIENDLY HORSEPOWER.

Good luck.

If you want to drop a V-8 in, go for it! The only thing I don't like about it is that you are doing it to a TII which is rare. N/A's are all over the place and would leave more TII's for us rotor heads. However, good luck with the swap...you'll have a beast when its done!

you need the turbo driveline though and the brakes are a hood feature. i would rathar buy a whole non running turbo then get pieces over time.

do a ramjet 350. hook up a 12v sorce to it, and u got instant efi, without running harnesses, and ecu problems, only downfall is the price.. i think its around 6 grand

LMAO, are you serious?

I can stand in my totally competed V8 RX7 engine bay. That is, with the engine, all wiring, and accessories in the car, I can STAND on the ground in my engine bay. I have enough room for 2 T88s and all plumbing, without issues.

Don't believe me? Take a look-

Now, I am a genius (look, I can even SPELL IT) and all, but come on, at least try to know what you're talking about before you spout off misinformation.

I'm not going to get into the weight issues. "Don't put a V8 in it, it'll kill the handling... put in a 20B" LMAO, do you have any CLUE how heavy a 20B is?

LS1/T56 is by far the best combo for a 2nd Gen. If I only knew then what I know now, my swap would've been that setup.

Good luck-

This is the "Other conversions" section...as I see it there are 2 types of engines...Pistons and rotarys...and if its a "Other converion" its going to have pistons, if you dont like it go find some other thread to screw with.

dont forget to show him the pictures of the LS1 twin turbo FD lurking around ;-)...thing is soooo bad ass...a guy on torquecentral owns it i believe.

since im nearby, you should probably let me have the old TII motor out of the car :) But seriously, if you are interested in selling it cheap, let me know. L.STAHLMAN@COMCAST.NET

I noticed that in my area you can buy any # of 2nd gens w/ bad motors for a bag of dirt. Too costly to rebuild? My $200 '87 recieved a junkyard LT-1 350 and 4L60E combo. Tons of room, great handling (51/49 w/bias), 20+ mpg and ship loads of torque! Now I have a nice 2 seat sports car that really rocks. Oh, yeah; no hood mods so it looks stock.

Now, dool, how much did the whole project cost you? FC/lt-1 seems like a nice college alternative to the fd/ls-1 beast I want to build eventually. Hell, I may even go FI with the lt-1 eventually.

Just to chime in here, I did the LT1/700r4 swap into a 1990 gtu and kept all acc's including the power steering, custom hood, exhuast, TII diff and half shafts, 4 piston brakes and more. Spent less than 6 grand inlcuding the price of the car. Ran a best of 12.8 in the 1/4 and also get 20+ mpg. All it takes is time and a few brain cells.

Stop and think
 

If you have the cash to buy a T2, trash it, buy a crate engine, buy 2 turbos, fabricate everything nescissary, and want it to be reliable, you are going to spend serious money. Why don't you just get a 2000+ Corvette? They would cost about the same in the long run, except you get a chassis and engine that were meant to be together.


By the way, do the valve covers on that V8 say Mazda? That's awesome!!

VERY few of the folks who have done the V8 swaps have bought crate motors. Used motors are most common, a lot of times with a fresh rebuild. My particular engine is 34 years old, and this is the 4th car it's been in since I've owned it - I bought it used. I have just about $7k in my car and it's about 5-6 seconds faster than it ever would have been as an N/A rotary. I even spent more than most because I bought all NEW 4 piston brakes, wheels, seats, and electronics. My FD with an LS1 will cost right around $16k when all is said an done, including fresh paint, wheels, the car itself and a more powerful and reliable motor than it used to have. Most bone stock FD's are going for that much or more.

Corvette's don't come with turbos, so you'd need to fabricate everything there as well. So it would be more expensive because you'd have to pay (a lot) more for the car first.

Most of us also decided to use piston engines after one or more rotaries didn't make it. I'd say only roughly 10% bought the car with the intention of performing the swap. I know I didn't plan on it - I bought the car before I had any idea it could be done.

Probably the most fun of doing a swap like this is getting rotary fanatics riled up. It never fails to amaze me how worked up people get and the shit that people say about 'how lazy we are to not learn to work on the rotary.' If it was that great of an engine we wouldn't HAVE to learn - and seasoned rotary mechanics get their experience by how frequently they need work.

i love how the flamers get told off. it's great.

i admit i used to be a piston vs. rotary doof, but that was before i owned one. now even the slightest smoke coming from my exhaust scares me. i personally dislike chevy, but the LS1 is a nice motor, specifically for our cars. if i get a job that pays better than dick/hour i'll be saving up for it.

if my wallets were huge, i'd get an AJ V8 from ford though. something about 32 valve and throttle bodies just tickles me.

^lmao...

Alright...lol I have a 87 GXL with a blown engine...
I want to put an LT1 in my FC. Maybe find a wrecked 95 camaro or something, and rebuild the engine. I want to do the whole project and have it under $3k. I can get a 302 really cheap, and my buddy has a shop that he says "for 1k i'll build that engine to 450hp" but... I just want to throw a pretty much stock lt1 in the car.
Would the 94-97 Camaro Z28 engine and tranny be a good fit? I know that some of them come with a 6spd(or do all of them?) and I would probably prefer 6 to 5.

Is it possible to do the conversion under 3k?
with buying the kit from www.engineswaps.com and doing it myself? I'm sure I can pick a motor and tranny up for under 1k, and the kit costs like $1500 for everything.

:( So many questions...

im putting a 383 v8 in my car. why? because its MY car and I can. if you dot like it then too bad.
