Hello,
This is my first post so YO! I am looking for a new car and the 2nd gen RX7s( god I hope I am typing that right if not I am very sorry) is catching my eye. I looked on a few used car dealers and I found 1987 Mazda RX-7 for 5995. Its a TII with 70k miles. This is a good deal or a cheating biznitch. I really dont know the value of older RX7s ,but I know the newer ones cost lots. If anyone else has a 2nd gen RX7 they want to sell for under 8k give me a holla. Thx in advance guys.

 

well first you do the obvious. check for leaking oil rust try to get a compression test done if u can too and welcome to the forum.

 

IMHO, any RX7 is a good one, but I would do a compression check, and drive it, and maybe have a COMPETENT mechanic look over it.

 

It's a cheating biznitch, assuming you pay the asking price, which you shouldn't. The advantages of buying from a dealer are the option to finance and a possible warranty. Otherwise, you will be better off buying from a private party. FYI an $8,000 2Gen should be a pristine show car. Usually these cars sell for $4,000 +/- $2,000. The newer 89-92 models make up most of the cars in the top end of that price range.

The Kelly Blue Book prices are fairly accurate. Make sure you understand the definitions of the condition values (Excellent, Good, etc.).

try cars.com, I found and 88 Vert for $1,400 on it earlier this spring. Also, have you check the adds on this forum?

 

Thx alot guys. How easy is it to get these things in the 13s-12s. Do the engines blow easy? How do I get all the things (i.e. the comperssion check) done at the dealer? The "86-88" are twin scrolled are those gonna perform better with aftermarket turbos? Also, should I look at the tubos? Thx again.

 

hook a boost guage

the stock one sucks

so if you want borrow one from someone hook it up and tape it to the windshelid.

thay last long if you take good care of them
oil change every 3500 miles airfilter and fuel filterchange at least once a year. and so on

 

I thought they were twin turboed? Doesn't that mean that they have two turbos?

 

Turbo 2, not 2 Turbo

The 3rd Gens came with a twin turbo, 2nd gens got a single turbo with a twin scroll system (only one turbo though... )

 

It's not how easy, it's how expensive...

only when mistreated... or unlucky...

either take it to a competent rotary mechanic, or bring one with you. It is important that a mechanic with rotary experience checks it out, 'cause it's a bit different from other engines

Wouldn't hurt, check for cracks in the housing and manifold... but better to have a mechanic check it

 

Oh ok thats pretty cool. Well after the 86-88 they used a new turbo system. How is it different from the twin scrolled. Also, how much money does it take to get these into the 13s-12s.

 

there is a big difference between 13's and 12's man. some people hit high 13's with intake, exhaust and a boost controller. 12's is a little bit harder.

 

Im also in the same position as Dtizzle and im checking out a 88 S4 Turbo II. At this point im not looking into aftermarket performance parts but rather restoring it back into good condition. Does anybody have any advice?

 

so like are the sticky FAQ and New Members posts at the very top of the first page of posts not working or what? check them out...most basic questions can be answered there.

 

The turbo has a twin scroll turbine housing and a compound turbine wheel, but a conventional compressor. The effect is that is feels like a twin turbo system, but it is actually just a single turbo. See the brochure for pictures:

LOL, the twin scroll turbo doesn't make much difference when it is in the trashcan because you replaced it with an aftermarket turbo. If you don't know what "twin scroll" means, then see the link above for a picture and description.

The 89-92 engines have a better turbo manifold and wastegate, so they can take more boost and will make more power with the stock turbo. Once the turbo is replaced, then the turbo and manifold design obviously don't make any difference because they are no longer on the engine. The 89-92 engines have slightly higher compression rotors, which may or may not be a good thing, depending on what you want. However, the 89-92 rotors are also lighter, adding another 1,000 rpm to the redline, which is always a good thing.
