noobie with a v8 rx7 any advice?
hi everyone. just got an 89 rx7 with a 350 last night. dont know much about these cars so i thought i'd better find a forum with some smart people in as i am not when it comes to cars. the engine is a 60's 350. bored 40 over with cam, heads, flat top pistons, eddlebrock rpm intake and eddlebrock carb. it has a 400turbo trans in it right now but i was think on putting in a 700r4(if thats even possible) the things i listed is what he told me last night. have'nt driven the car yet as the motor needs to be put back in. he pulled it after spinning a rod bearing(not sure what that is... but he spun it lol i'm hoping to have it back on the road in a couple of weeks. my budget is 1000 any idea's on what i should do to make it better before i drop the engine back in? he said he could run 11's in the quarter might be lying, i dont know. the guy who hooked me up with this car seen it run and he said it was just "sick fast" anyway thanks for reading take care

You are in the wrong place if you need help with the powertrain, but anything else you can get info for here. The car weighs around 2800 lbs and is probably pretty fast (at least much faster than your fiero) assuming the guy isnt lying about mods or anything.

Is the car completely gutted out (interior)? Stock '89 is about 2900 pounds so 2300 seems far too low a number unless a lot of material/items have been removed.

Try www.v8rx7forum.com, they're a lot of help without the flamming that goes on here by the 17-year-olds who don't even own Rx7's.
Anyways, I've got an 86rx7 with a 383 small block chevy. Before I "cammed" the motor it made 280hp at the wheels (380at the flywheel) and I did a high 11 in the quarter (that's also with 460lb/ft of torque at 4,400rpm for the rotary guys snickering at 380hp
.
I don't think you can stuff a 700r4 without cutting stuff up. I've got a 200r4, fits good but was a pain to get working right. But you'll definitely want an overdrive!
Save your money, you'll need it for gas, lol. LS1 + T-56 tranny are really the way to go with these cars. what kind of carb are you using?

Also another good (new) hybrid import forum
Complete with understanding and not so retarded adults that seem to think a rotary fell from the heavens and is the only thing ever invented...
Your 28 and your blind (this is apparent in your ignorance) otherwise you would see the potential around you...
We like cars we dont particularly like rotaries who gives a **** if you dont like it...
Did anyone ask your opinion? Did anyone call you from the bench (cause its also apparent your a bench racer) and say "Hey computer geek!" "Come say something about what i just spent my money on!" You lemming..... WAKE UP! Theres a whole world out there start looking at it...
But hey, maybe its in your genetics...
Some people are born to follow, that tends to work for lemmings...

Post #15 With a bang.... I hate this forum allready....
Hey did you mean a 200 metric instead of a 200r4? Never heard of a 200r4...

There were no survivors
Yet neither side is mature enough to be the "bigger man" and just ignore the stupidity (on both sides) and just keep threads on topic.....
Some of the common conversion companies I've heard mentioned are Granny's speed shop and hinson supercars (ls1 conversion specialist) You might possibly get some help contacting them with a few of your questions.

If your budget is only $1K than you might want to reconsider/re-evaluate where you are in regards to the car hobby. The swap will take about $3-5 for a "budget" motor, which in your case you already own. That's a huge step in the right direction. If you can source another tranny for really cheap than great, otherwise... you might be using up your budget right there.
Also consider the differential. The stock TII will work if you are not abusive to it but it will not last forever. If you have a NA differential - it will break very soon, be prepared.
As far as Grannys and Hinson - are you planning on buying something from them? If not - step in their shoes - why would they spend time out of their day to give advice to people when not profiting from it (i.e., why they are in business). Not saying they are rude but they are trying to make a living too - so time = money.
www.v8rx7forum.com is a better forum to ask specific questions since it is dedicated to what you are in the process of.
What's funny is the whiner above to says put the "heart" of the motor back in... but he has a "stop global whining" avatar... irony is wonderful.

You can bolt a 700r4 in but, it requires a truss type transmission cross member. They are available from <www.grannysspeedshop.com>. While you have the engine out replace ALL the main and rod bearings. Use Clevitte 77 bearings (they are the best!)you can get the rod and main bearings for like $200. IT IS WORTH IT!!! I am currently converting my 87 Turbo II to a 450 hp chevy 283 and all my conversion mounts and brackets are from them and their parts are high quality. Anybody with a t-56 transmission for sale let me know!

I didn't say he WOULD get help but that he MIGHT. Kevin Landers, the guy running Rotary Resurrection for example, gets tons of e-mails of questions about various RX-7 stuff and gets back to as many people as he can. Heck I even had a question for him because one of his write-ups seemed a little vague to me and he even wanted my feedback to see if he could make it clearer for others who would try his write-up and get stuck at the same spot. That in itself has made him one of those "stand out" guys to me and if I ever needed a service he provided, he'd be one of the top people on my list to go to. Its all about how you present yourself to potential customers. I don't know much about v8 swaps in RX-7s and I'm not going to try to act like I do. I just point people to places where I know the knowledge is.
As they say in business "its harder to get new customers than keep old ones."

wow interesting responses :)
ok to the guys who gave me advice on the tranny and engine thank you. to the guys who just ripped on each other .... thank you it was fun to read lol
ok the engine is at the machine shop right now. my budget went out the window i dropped 1300$ just on the machine work
my budget is connected to my wife and i's house building budget ..... she just dont know it yet lol lol lol so ya.... if anyone has a warm sleeping blanket i could use it, cuz the dog house is cold up here in michigan 
ok back to the engine. yes they are putting in new cam bearing, boring it over to .060 reworking my heads and getting me a complete rotating assembly kit(eagle). i will be picking it up the end of this week. price for all that was 1300$ i still need to buy my electric water pump, headers(flowtech 1 5/8 to 3inch exhaust), electric fan, and possibly a new carb unless i can get the eddlebrock i have rebuilt. i'm using the rpm performer intake. thats the everything for the motor. not sure on the lift of the cam he told me but i dont remember. he said i would have at LEAST 375hp but probably 400hp.
the tranny, this is where i'm a little lost. i have the trauss cross member thing someone mentioned above. so with that am i going to be ok with the 700r4 ? he had a 400turbo trans in there and he said it was real fun up to about 50mph (woohoo look at me go) lol i want to be able to drive this thing to work which would require the freeway. i also wouldn't mind being able to race this thing at lapeer dragway which would require faster then 50mph so any advice on the tranny is appreciated.
thanks again for all the input.

Get the 2004r its the same length as a th350, any 4 speed or a T5 only the output shaft spline counts are different 27 or 31.
th400, m22, BW super t10, (700r4, th400 (longer)) 31 spline
th350, m20, m21, saganaw, t5, 2004r 27 spline
a metric with "metric" on its pan is a relative of a th200 not a trans you want
Stock tire size @ 70 mph in 4th 1:1 with a manual is about 4000rpm, add 200+ rpm for a non lockup converter. Your performer manifold may be too tall for a standard hood, shortest is best. Also must check clearence of your distributor. HEI will most likely hit the firewall.

any cooling issues?
thanks for the info. unfortunatly i picked up a 700r4 last night before reading the last post it's built with a 3500 stall... i think i'll have to change that. anyway i'll keep my eyes open for a 200r4 as well. i do still have the 400turbo the previous guy had in it to. i'll check craigslist and see if anyone is interested in a trade.
is anybody having any trouble keeping there engine cool with the stock radiator in this set up? i seen the one on "granny's" web site i just dont want to drop another 450$ after spending all that money on the motor. the guy i got the car from said it worked fine. the machine shop said i'm probably going to have a hard time keeping it cool, being bored .060 over. thanks for all the input.
