| To V8 or not to V8?? - Click HERE for Original Thread |
| WookeysRX7 |
Well just like it says above i am contemplating whether or not to put a V8 into my 2nd gen. RX7. First off, the rotory in my car is stil good but its an N/A. So no turbo means no real go! I can streetport the engine, intake, header, exhaust and then thats about it for that engine. Nothing really else can be done unless i wanna waste the money to get a supercharger. And i dont think Nos would be such a good idea for the power i want :D . hehe... Another thing is that rotories are less common which means parts are harder and more expensive but on the other hand rotory's are stock and what other car besides a mazda has a rotory? NONE! Now for the V8 i will need the engine(obviously), tranny, driveshaft, rad, engine/tranny mounts and new springs/shocks. But the thing is about the V8 is that i will have way more power and i mean WAY more power. Parts are easier to find and cheapier(usually) and mechanics (i will be doing most work but in some cases) are a helluva lot more knowledgable about them.
I have 2 engines that i know i could possibly buy. 1 is a 383 pushin 400+ HP and my neighbor has a 400 small block thats just plane old nuts! i dont know how much Hp it has but before he rebuilt it he had it in his station wagon, hehehe 200Ft burn outs, destroyed mustangs, and kept up with a Porsche 911 until the higher speeds cause the ol' 3 speed auto doesn't work too good up at high end. haha.. |

| I would suggest selling your car and buying a turbo 2G. Why would you want to bastardize a mazda with a domestic V8? :wtf: :kill: :blast: :slap: :stickpoke: |

I think it would be an interesting swap. I've heard of swap kits made for v8's. Hey, people swap v8's into old school z's why not try it with an rx7?
(ps - richard, Chad's just a good ol' redneck... he likes rotary but doesn't want to take it to a new level... old school) |

| keep a few things in mind... first with a v8 the wieght is WAY farther forward. people will try to tell you that you will not ruin the handling but ask any of the people around here who have done it, with the wieght forward that means less traction, worse handling and worse braking. then consider the cost. kits to instal these are 1000-1500 us for a good one and you will regret not getting a good one. second you will need a diferent trans and driveshaft,radiator modified crossmember to clear the oil pan and the list goes on and on. in the end to do a good well done and good running conversion it will cost you close to ten grand. dont be fooled these things dont happen cheap. if you want to spend ten grand on your car we can eisily put a turbo charged 400hp rotory in it....... pistons suck! redlines are for sissys. :angry: |

hahahahahahah! :lol: :lol: :lol: :lol: :lol: That last line... is awesome. "pistons suck"
IMO - rotaries are great... awesome engines, just a little costly to fix because they're uncommon except to the RX7, at least here in AB. We have very few competent ppl that can fix these cars, aside our rotor head friends from Edmonton Rx-7 :D Can't wait till I'm done school... then there'll be a classic 3rd gen 7 in my garage... haha :D |

| LMAO! I knew this was coming. But Conroy, to tell you the truth i have talked to many of these guys that have done the conversions. Did you know that the vette engine is 70LBS lights then the rotory? Because its an aluminum block. But very true that the weight transfer will be a helluva alot different with a 400 Small block. haha... well Conroy, i am looking for an engine that i can spend like tops $6000 on. I'm tired of being so damn slow! And i want an engine that will last and not have apex seals blowing to shit! Any info on engines or what i should to for an engine with $6G's?! Poossbily a T2 swap will be in hand?! but dammit it needs to be good T2~ :bigthumbup: |

| luv'n my 7 |
DON"T you even think about doing this!!!!!!!!
With the amount of money you are going to spend and the fact that you have to change the drive shaft, tranny, rad and all that other shit, just go and swap in a 13BT. I've seen an rx7 in THIS city that had a mustang 302 under the hood and i almost died! :tear: You own a wonderful car with loads of "personality" don't change the heart and soul of it with some big ugly piece of crap, american made bullshit!!!! Rotary's are so simple and with a little time and effort they can be down right incredible!!! Go with the turbo if you want more power!!!! |
|

| redbaron303 |
| Don't get too emotional man.... "it's just a car" hahaha, but you're right they do have personality as they so different from the rest of the pack. Still it remains his decision as it's his car! |

As I know where there is one for less than $6k :D
Blaine, your jdm motor, was it rebuilt? I don't recall seeing a post saying it was, and how many KM are on your motor? Just curious? |

The JDM wasn't rebuilt.
On Mileage, it's JDM, "between 40-50,000" miles, just like every other JDM motor. |

i didn't read other people's posts but here's my 2cents:
V8 rotary = NOT V8Less
GET OFF THE BOARD!!! :D :D :D j/k

| Alan's yellow 2nd Gen RX7 with the Ford V8 is a fun road race street car. He always pulled me easy when I had the KA and hearing the V8 rumble from that beautiful package was nice. I say go for it or put in a 13BT or 13B REW. Either way will get you the power you need. The Fords fit easier than the CHEVs. :bigthumbup: |

I like V8s... those that come in BMWs with 'M' badges!

I'd say that the best road to travel here would be a modified turbo rotary, You get the unique free reving, ultra smooth power only a rotary can deliver, plus the handling will remain sharp, and it will keep the value of the car intact.
But realistically the V8 gives you straight line insane power, confident crusing ability, and only sacrifices handling. The engine is easy to work on, meaning anybody from a trailer park can change your oil and adjust your carb. But on the otherhand, seeing as you've crossbread a domestic with an import, allot of little things may tend to creep up on you and cause long term problems. My advice is if you want a car that has v8 power and globs of torque, and your not concerned with things like turning corners, than dont chop your 7, sell it and buy a mustang. Everyone assumes that swapping in a v8 is cheaper than builing up your rotary, but your wrong. Sure finding a qualified mechanic to work on your 7 is hard, but finding a mechanic to change the clutch on a bastardized 7 is even harder. For the money you'd spend on this swap, you can buy a good healthy V8 including the car it comes in too.
Whatever you do hope it turns out and makes you happy. |

Uncle Ben(is this wilson?), i see your point and its a good point but for one thing, i sure as hell am not going to buy a mustang. First of all, Fords suck, haha If its not imported it better be chevy! Second, i thought it would be cool to have a unique car. Now seriously, how often do you see an RX7? Let alone one with a V8!! I have talked to guys that have done the swap for like 4G's and its not a hack job! Changing the clutch should be no different then changing it like it is now. You still have to remove the driveshaft and the Tranny to get at the clutch! Sure the Chevy tranny may way more but thats what a tranny-jack is for. But anywase.... This isn't forsure yet and its all just an idea still so if anything were to happen whether it be putting in a V8 or a different rotory, it wont be happening until next year.
1mns13, who's your allen friend? I have never seen him around in the city with his 7. Is he on this board or does he have msn? |

| ask this allan guy how much he spent on his swap? hahahahaha then price out an all aluminun corvette v8, oh and buy the way its still not lighter than a rotory! and the engine has to sit almost half way farther forwards than a rotory. but if your serious about the 6g,s budget i have all the parts to build a high perf t2 with turbos and exhaust upgrade computer and injectors probly close to three hun hp you could do it for 6. do the research carfully and if you cannot pick the engine up buy yourself and put it in the back of you pickup,by yourself and then unload it by yourself ITS NOT LIGHTER THAN A ROTORY!!!!!!!!!!! redlines are for sissys. |

| haha conroy, you're funny.. So bitter towards piston powered vehicles! :bigthumbup: hehehe. Yeah, i am pretty serious about the 6 grand maybe a lil less. I just want a car that freakin quick. I am tired of being so damn slow and I wanna be able to put those damn Rustangs to shame! along with civics and others. Now, would that be 300 Hp at the wheels or the fly wheel? and aww crap! i would need a new tranny would i not?! |
|
|
| 4kruzn |
| to be conservitive lets say at the flywheel. and no you would not NEED a new trans at first. we can put the turbo motor into your car with the flywheel and clutch system you have but the stock clutch will prove to not last long with that power so when it wears out you will need a high perf clutch. I dont hate pistons, just swaps like this do effect far more than people tend to tell you and I hate to see people get into them without knowing what there getting into. if you do want a v8 buy a northstar cadilac 32v you can get them for around 5g and they come with 300hp stock and get 30mpg. cool eh? ;) |

| To speak to Allan and learn about his car, Raymond at Silverstone should be able to get a hold of him. If you want to keep an eye out for it, look for wide flares, 17x11 rear wheels and yellow. It has seen road race action in Calgary. To the best of my knowledge it has not beeen drag raced. Allan is a nice guy, but rumour has it (oh never mind). If Raymond is not helpful, I have another source. |

| why wouldn't you dump a v8 engine into your ride if you have the dough. turbo's are great if you have no other options, but displacement is a beautiful thing... |

| damn right! Another thing is that when you have turbo you always gotta worry about cooling it down and changing the oil more often. :thumbsdown: |

One more oil change, better gas mileage than a v8...? Buy a turbo timer... $150.00 from Apexi and you won't have to worry bout it :D |

not nessecarily better milage... a lightly driven v8 will probably return similar milage to a more harshly driven turbo, and they will perform similarily, especially if that turbo car is kept on the boil as needs be done to keep boost up to nice levels.
basically it boils down to this (IMHO) your going to get a more responsive, slightly less nimble car which is way more fun to drive for about the same cost as going with a big turbo and a built 13b, but then again, chevy v8s have been around for what 50 years, using the same basic engine layout and design...
just like the colt 1911... almost 100 years old and still a damn fine pistol design.
you think maybe its been done that way for a reason, like the fact that it works, and damn well, so i think youll have a much more reliable engine as well.
reliability and speed are king in my books, after all, the fastest car in the world aint worth a shit if you cant maintain it. |

:thefinger: Hey Chad,
Eat my ass about sums up my comments. I may wear a denim jacket, drive an old Ford from hell, and wear jeans but anyone that know me knows I'm not a Redneck. And I never called you a redneck, I was saying that if you want a V8 then get a Camaro or a Mustang and join all the old bngers that drive those cars. What you do is your business but..... seems like a lot of work for little gain to me. It may be easy to find parts but what happens when your home-made motor mounts break off or your custom drive-shaft is too long and you blow your diff or tranny tailshaft. ;) Now, my car being hardcore I can't listen to anything in it cuz I'd have to get rid of my radio delete plate. And when you wanna race, bring it on! I'll hand you your ass any day you like! :angry: And just cuz I'm not a 17 year old punk like you doesn't mean I'm from the white snake era! That hurt man! I'm 22! See ya out there! :P Oh, and for you, block hugger headers and some flowmasters will run you......... $2,546,387! But just for you!

I recommended the 302 if V8 is your choice but, I feel 13B REW is the way to fly, reliable powerful and most importantly the smoothness of a rotary.

oh Geez.....first of all... Karl, i was jokin. :blink: second.. i'm not 17, i am 19 in less than 3 months, 3rd, i can use the stock 4:10 gears from the 7 which are well built and if i need a new diff my neighbor can hook me up with one for cheap, 4th my engine/tranny mounts aren't home made, they are made by a company down in the US that fabricates it specifically for that reason, 5th, an RX7 is WAY lighter than a rustang or a camaro, 6th, the driveshaft wont be too long, any person that knows something about drive shafts and diffs can measure it correctly and then send it somwhere to be shortened and then balanced properly, :blink: :D Don't wanna cause havoc between RX peeps, just doin my own thing.. :o :D
1mns12, i am either putting in a 383 stroker thats pushing 400+ HP or a 400small block that has about 450HP! hmm........ do you think that that'll make my car go fast? i think so! :bigthumbup: |

Well Chad. A Mustang or a Camaro both weigh in at around 3400lbs. or so depending on trim. Next, your car with a V8 will probably weigh in at about...... 3300 - 3400lbs. 400hp is a great idea; but with the open diff in your GX you'll be well on your way to spinning one tire for as far as the eye can see. Finally, I don't know who your neighbor is but if he has some magical way of making diffs stronger let me get in touch with him cuz I'd love not to have to replace mine a few times this year. Cuz and RX-7 diff is an RX-7 diff is an RX-7 diff. And unless you're redoing the suspension and going with a solid axle you'll have..... an RX-7 diff. None the less, you'll do what you want, and if it works out, GREAT!
I'll see ya at the track and you'll see my tailights! :D

WookeysRX7 or Chad however you prefer to be addressed. Have you considered chassis stiffening ideas? The problem with excessive displacement is an overabundance of torque, which can cause trouble with chassis. Are you looking to build a fast car or tire frying monster? Do you plan on keeping this a street car or race car?

"gawk factor" really shouldn't be something you're looking at achieving with your supposed $6000 engine or however much it costs
if you want gawk factor, $6000 could also be put to good use in penis enlargement, whip it out onto the hoods of chick's cars & you'll REALLY have some "gawk factor"
