v8 swap into 85..
 
hey my friend is sellin me a 85 with only one rotor firing(or making compression) for 350 bucks, so im thinkin of swappin a 350 v8 with aa TH200 4r transmission in it using grants v8 swap kit, are yall familiar with this? since it only adds around 75-100 lbs and the front ride height would still be in spec, it wouldnt effect handling hardly at all.. any tips? thanks!

my goal is a stock lookin BEAST.. mid 12s..

what do ya mean? oh yea ive heard stories of yall bashin on ppl wantin to swap.. whats the big deal? not like its a ferrari.. siiigh, poor single minded ppl.

Directfreak 02-19-03 08:35 PM

PM Winnipeg85GSL on the forum. Do a search through his threads. Much has been covered there during his V8 swap.

stinkfist 02-19-03 08:37 PM

Ouch, I was about to jump to your defense before that last comment.

FWIW. I like the idea of a V8 in a first gen. I love the rotory, hell I have three RX-7's and 5 rotary engines in my garage, but nothing like a V8 in a light weight chassis. Ever heard af a car called an AC Cobra? Not exactly slouches on a road course.

GaRn 02-19-03 09:42 PM

yep
 
yea, of course i have! i love most all cars.. though i dislike fords, except for the new cobras!

GaRn 02-19-03 09:44 PM

oh yea the 1st gen rx7 looks badass to me, i love the body shape.. same for the 280z's those things are beasts, i got a vid with a supercharged 350 in a z car, and he was goin down the highway and all he did was mash the gas and started burning out.. crazy.. also raced a r1, so he was runnin low 10's or high 9's cuz he kept right beside him..

onepointone 02-19-03 09:51 PM

i like the idea too.. im all about doing the swap, my dad has a chevy 4.3 in his 87 rx7. its beast as hell, but they are 2 completely different worlds.. (my 85 gs and his)

but yea, if you do a search, there is alot of info. and if you go to www.grannysspeedshop.com they have writeups on what all is needed... goodluck

Ok, I'll chime in since I'm not 100% opposed to the whole v8 rx7 thing. Never in a million years will a boinger go in a rex I own, but if you wanna do it then go for it. This is definatly not the forum for you though, most of us are here cause we like the Rotary engine as much as the beutiful car Mazda decided to put it in, so coming on here and talking about putting some chevy motor or whatever in a car that should be rotary powered isn't gonna sit very well. A better site for what you wanna do would be: http://www.v8rx7.com/ That will be a much bigger help than us.

moprblms 02-19-03 10:45 PM

keep it rotary !!!!!!!!
keep it real!!!!!!

Winnipeg85GSL 02-19-03 11:35 PM

Don't mind them they are just jealous of the tire-smoke producing power. :p: My swap was done with a Ford 302, possibly easier because of the front mounted distributor and the lighter weight. A 350 is gonna be more than 100 lbs over stock unless you are using aluminum stuff.

rgus30 02-19-03 11:59 PM

Do it
it is a great project
go to grannys speed

o god, i saw that video of the 240... it realy almost makes me wanna do a v8 swap someday to a diff rex , but the rotary engine is what makes the car so unique... but a Super charged 350 crate..... in a lightweight car... cmon dont tell me that wouldnt be fun...

RotorMotorDriver 02-20-03 12:58 AM

Yeah, in a 240Z.

~T.J.

PS - I have 3 videos of that car. One of him just revving it in the garage (you can see the R-1 he races later in the background), another of him racing the R-1 (or whatever the bike is), and the third of him doing the burnout on the road.

Manntis 02-20-03 01:18 AM

nevermind the chebby - put an Audi V8 Turbo in there and have a lightweight power plant with 346bhp and 350+lb/ft of torque - WITH a warranty! :drool:

680RWHP12A 02-20-03 02:14 AM

would be nice.. but goodluck getting all that wiring :D

nosajwrx-7 02-20-03 08:49 AM

Plus, I bet the Audi transplant would be pretty costly.

Perhaps the most rational, logical reply I've ever seen as to why this thread is misplaced...this needs to become the standard reply to all the V8 threads that pop up...:cool:

GaRn 02-20-03 12:28 PM

Look, I can't live with the idea of a boinger in a rex, but it's your choice, so... I just wonder why this time so very few people have been flaming :-) These guys are getting weak! Anyway, I also believe, since there's the same question all the time, some kind of sticky would be at place. Like: V8 swappers go V8rx7.com. Cause it causes heartache to be confronted with those who refuse to understand the Rotary is a major part of the Seven. And indeed, Manntis is right: if you do it, do it right, go Audi (or Lexus maybe?)

onepointone 02-20-03 02:43 PM

my dad spent around 3k on his.. and its probably pushing around 300hp (been bugging him to get it on the dyno) if your mechanically inclined and have no problem fabricating things.. it shouldnt be too bad. it did take about 6 months though..

rotor vs. piston 02-20-03 08:11 PM

I have a '85 GS with a V8. I used grant's kit, but put a T-5 transmission in it. If you want to ask any questions please email me or PM me anytime.
