v8 engines
 
k, whats your favorite v8 engine. I'm interested in v8s in sevens, so i'm just looking at v8's. Please don't hate me....

Max7 06-18-04 01:20 AM

Ferrari makes some wonderfull V8's there is one from a 355 on eBay right now for just over $30k with ECU and wireharness.

get a mustang. dont rape a seven.

Jeff20B 06-18-04 02:21 AM

This belongs in the lounge or the Other Engine Conversions subforum.

heb09 06-18-04 04:48 AM

v8 engines are great motors. Just dont put an rx7 threw its misery doing a conversion :P

mwatson184 06-18-04 07:56 AM

Wrong place to ask probably, these guys aren't going to help out much. Go to the performance section of the forum and click on "other conversions", you will find a ton of info there. I'm swapping a 5.0 into one of my sevens pretty soon. I will still have 2 rotary powered cars though.

im a chevy guy, and i say if you want something still economical with alot of power get a 350. if gas isnt an issue get a 427, if you are drag racing get a 454 or 502. There is a sweet 427 that a shop makes its TT and it pushed an escalade, the big truck one, 0-60 in like 4.46546 something seconds, goto caranddriver.com and look for escalade it will come up as a test. it gave me the idea to put it in my nova, which will be completed soon and then everyone in my area will be destroyed at the power of the TT in a car that weighs a little more than an FB

Feds 06-18-04 09:04 AM

A Buick/Rover 3.5l V-8.

All aluminium, not too big, not too comon

dark mephisto 06-18-04 09:09 AM

thanks, yeah, i wasn't sure about where to post this. I was looking at a ford 302....... i don't think i'm gonna do it, but i like the 350's.

mwatson184 06-18-04 09:42 AM

cheaper aftermarket for the 302.

WonkoTheSane 06-18-04 10:39 AM

Just in case you haven't heard of the site, goto v8rx7.com, it's a forum like this dedicated soley (is that a word?) to converted rx7s..

Cloud 06-18-04 05:53 PM

The Ford 302 is the easiest swap into an FB, and can make a ton of power on the cheap.

Rx7carl 06-18-04 06:41 PM

Do you want me to move this?

Jeff20B 06-18-04 09:19 PM

Please.

dark mephisto 06-19-04 12:36 AM

meh, go for it, i got what i wanted

mar3 06-19-04 06:03 PM

It would have to be the IA aluminum Pontiac block KRE is about to produce with Eddy heads...lightweight and capable of 700+ HP, 650 ft-lbs of torque and runs on 93 octane with a 950 rpm idle....but what would you expect from a 550+ cid engine, eh??:cool:

kettlman 06-20-04 12:53 AM

why move it? he's talkin about a 1st gen.

XLR8 06-20-04 03:05 PM

V8 FB's are not Rx7's.........Its just not the same. Never will be. No matter how much power they make, how fast their 1/4 mile time is, they will never handle the same and that is the soul of any true sports car. If ya want a V8 project car get a Fiero. But, ofcourse I am one of those die hard Rotary guys that goes and gets a rotor tatooed on his body and everyone says "geez man its just a car" to........But NO dammit its not just a car:)

PS its amazing how many people ask me what my tattoo is....I often tell them its a cult symbol.

rotary emotions 06-20-04 04:00 PM

If you must be so screwed up to rape a rotary car by installing a V8, at least put in a decent one: Lexus, Audi, TVR... But hell, not a pick-up truck engine, ok?

Lee Lyons 06-20-04 06:33 PM

No you got it all wrong. If you go with a V8 which we will have to disown you after you should go with a small block 400 out of a GTO. Do alittle work, and you easily got over 600hp. But you also have to have the $$ to afford the gas.

Jeff20B 06-20-04 06:37 PM

If you're going to install a larger, heavier engine, I'd personally do a 20B. More torque AND it's a rotary. It can also be done for a lot less money than you might think. How do I know this? :)

Reciprocating engines don't turn me on. I'd never put a V8 in an RX-7.

I bet a lot of the V8 RX-7 people here already had some prior V8 experience. It's the only logical assumption I can make. Otherwise it doesn't make much sense to swap in a V8 when you can great power out of a rotary. Even so, why is the rotary such a foreign concept to these people that they can't make the power they want without swapping engines? Are they too old-school (old/set in their ways) or dare I say dumb? Is it a cost issue (hard to believe since rotaries are so cheap to build for power)? Why then are there so many piston powered RX-7s on eBay? Maybe the swap isn't as cool as they first thought. Or maybe they're trying to recoup some of their expenditures? Meh, I'm probably too dumb to figure this one out.

I guess it boils down to personal abilities/preference in the end.

mar3 06-20-04 09:08 PM

No, it's usually cost becuase they have some raggedy ford or sbc lying around or can score one for $300 and they'd rather go that route...what does a rotary rebuild kit cost? If it's $300, then they really have no excuse except the very task of rebuilding the rotary means buying some tools or renting some tools you would never need for a boinger rebuild and then you're talking more money again...:cool:

kettlman 06-20-04 09:29 PM

so what you're saying is if he had a problem with the hatch latch, turn signals, or even a little light in a v8 rx-7.... you wouldn't help him?

high-RPM 06-20-04 11:27 PM

I've heard that toyota/lexus make a good V8 for the soarer

1UZFE
3968cc, V8, 32 Valve, Quad Cam, All alloy block, RWD,
265 Hp 37kg.m at 4600rpm

heb09 06-21-04 12:10 AM

I've seen a 189ci block do 10sec quarter mile in an old Holden EH which was street registered. You yanks always think bigger is better. Not true! Unless you plan to drag other top fuelers, wtf is the point of putting a huge block in the rx7? Your never going to make 600hp work properly unless you start doing some serious modifications and then its gonna cost a bucket load. Just wack a turbo on the 12a or 13b and enjoy!
