Does anyone know the name of the web page that sells v8 conversion kits. Somthing grany-rather I think.....

metalliman

V-8 conversion why would you wanna do that? Pistons and Rex's don't mix well kinda of like....like....a "**** taco" drink (half a shot of Tequila mixed with a half shot of Jagermeister) Worms and black licorice don't mix?!?! Blaaaahhh....

ghetto-rx7

I just cant take the power thats not there with the 12a. I'm seriously considering doing a 13bt t2 swap but why?

You can get way more horsepower from a piston engine for cheaper plus their twice as reliable.

But yes, I agree the car would not be the same without the rotary in it.

You're handling and braking will go out the window as a result, though. You can go with SS lines and bigger brakes to recover the stopping power, but there's nothing you can do short of a serious set-back of the engine (which means you'd have to cut the firewall to get clearance for the bellhousing...) to recover the handling because of the additional 200 lbs you'd be adding to the front with that blasphemous conversion...

Again...isn't there another Forum or website y'all can go to for these kinds of atrocities?! This is a rotary Forum, for Pete's sake!!

I'm going to do the ultimate rotary enthusiast's nightmare A hon-duh Vtech 4-banger in my rex

I screwed up, see the link below

Why not throw a supercharged Miata engine in there instead of a Honduh banger, Jeff? Keep it kinda factory despite the butchery.

While rotaries take to turbochargers best, there are some fantastic supercharger kits for the Miata 4 that free up very, very significant horsepower. I won't quote numbers as I've not done it myself but I know one fellah who convincingly claims a huge boost (no pun intended) to performance - and he's one of those sceptics who usually shoots holes in any mod ideas.

Hey Mike, if you still wanna do it, I'll trade you an 84 GS with no engine ready for a V8 for your GSL where your at .

Nah thats OK LOL You know im always playing, but seriously we will soon see what the rotary will do... Im only minus the injectors now

Hey Mike, is there a post that has some recent pics of that beast in it? I wouldnt mind seeing it again, I havent seen it since the manifold was off it or something like that...

Also www.rx7v8.com has lots of V8 information
as well, just ignore the body kits stuff.

OOPs. Did I just contribute to the delinquency of a V8 conversion?

Well recent updates are I ditched the POS 2nd gen oil cooler and went with an aftermarket racing oil cooler, some AN steel braided lines, a NOS fuel pump, and some misc other goodies. I will unveil it soon with a MP3 or a MPEG

You are so ignorant its sad sometimes. How many times do people have to tell you the same things over and over again? First off, a 302 with aluminum intake/heads is hardly heavier than a 12A. My car brakes no-worse than it did before and handles just like it did with the rotary in it. The firewall doesnt need to be cut at all, I don't know where you got this from?? Whats the reason you keep bringing up bad things about piston driven RX-7's when you've never owned one and have been disproved many times?

thats what i was wondering about. khaine_d said intercooler. i was thinking "why is he changing the intercooler?"

79+80_rx-7

IGNORANT??? WTH?

He is just sayin as to how the extra wieght IN FRONT OF THE ****** WHEELS.... handling will be shitty.... and brakes will be ALL up front instead of at the back......

OKAY PEANUT HEAD how many times do you have to read the same things over and over again??? Even though that 302 might not be heavier, the wieght is in front of the wheels... And yes the firewall has to be cut... so that the balance of the car isnt fucked up way too much... He got it from thinkin.... maybe you should try it... Piston driven RX-7's are bad things..... thats why they CAME WITH A ROTARY....

'Pegger, you're probably making the innocent mistake of calculating the weight of a bare 302 (even with aluminum heads) against the weight of a 12A with all accessories attached.

I worked on plenty of Detroit Iron engines from Allison Diesels to Chevy V-8s (Some at the Minto Armouries there in the 'Peg just before we started sandbagging in '97). The blocks alone are quite a heft.

Then you have to consider the deeper oil pan required, which mounts the engine higher in the car. Sure it will fit under the hood but you're transferring hundreds of pounds a few inches higher in the frame and affecting the center of mass (the very reason SUVs roll more in corners than low slung cars)

Then there's the far larger and heavier Ford Automatic tranny that bolts to the engine, again increasing the weight substantially.

As to real-world performance, there's a guy here in Saskatoon with a 302 in his car and he has to slow to 20kph to corner.

I can appreciate that yours seems to handle as well as stock, but the majority of people doing these swaps must be doing something different than you did (not uncommon on custom work) because they DO suffer the handling performance drops that Mar3 is mentioning.

Most advice given on here is based on generalities. There are always exceptions, but in general most V8 swaps into ReXes carry weight and handling penalties.

Ya but 302 would rape a stock or ported 12a with intake, exhast and a turbo if you through some weight over the back wheels

ghetto-rx7

If that guy isn't bs-ing then I cant see to bad of a performance drop.

ghetto-rx7

I'll tell you right now, that looks 50 times better than my engine bay as it sits.

Do you think its possible with some help to like fabricate your own mounts and everything? I just cant seem to justify spending 5 times as much as my car costed just to take the rotary outta it.

Alter the rear suspension for more anti-squat. Then, after the initial launch, provided your tires are sticky enough and you haven't blown any driveline bits out (to be expected if you'd foolish enough to try using a T5), you should have 100% weight transfer (front tires off of ground)

got MIG?

MIG?

MIG welder. Absolute must if you plan on fabbing anything.
