Hi!

Im new to the board, but have loved RX-7's for a long time now. I don't have one yet but I am looking at one right now, and I have a couple of questions for the forum.

Its an 87 Blue, non turbo, not sure of the exact model I there didn't seem to be any markings on it but it has the 5 bolt rims. The exterior looks beautiful. no visible rust, and the interior looks very good as well, blue cloth, no rear spoiler, power sunroof. The car has aprox. 197,000Km on it.

Anyway I had a few questions before I buy.

The Car is going for $1500.00 CDN, but it has oil seal issues, the guy says it runs fine for 10-15min then it starts using as much oil as fuel. He says I can have the seals replaced/repaired but as far as I knew once the engine was doing that it had to be replaced, which makes the car worth less than he wants.

Next question is somewhat dependant on the first
If I have to repalce the engine is it possible to put the turbo engine in?

If not are there a few low cost perfomance mods you would recomend.

I appreciate any comments u have, I like the car and probably am going to buy it. I have sports car crack in my blood, I get to drive both my friends MKII Supra and MKIII Supra Turbo occasionaly.. right now im jonesing for a fix!

Thanx for your time.

Hey, i have the exact same car. Well i got mine painted a different colour. To get a turbo engine in your car you need a few things, like a new drive shaft and some othe parts. But the bonus for the n/a is that it is quick, an they last a hell of a long time. Alot longer then turbos. so dont worry aout it. It's all god get another n/a engine, with a cone filter, take off the Catalytic converters! that is a must, when you have that many KM's on the car they get built up with **** and do damage to your engine!

 

Sweet!!!!

I have been readin' more posts and learnin a bit, I probably will keep it a n/a cause Im poor and my technical (car) knowledge is minimal and I will be relying on my supra friends to help me put in the engine etc, and I think putting in the turbo will cost more than the 24 of beer and party pizza I can afford to pay them hee hee.

They put the 6M-GE Jap spec supra motor in my friends MKII supra n(190hp from the 145-160hp 5M-GE) and it keeps up with stock MKIII Supra Trurbo untill 210Kph

But anyway, my MKIII buddy (Kingsoup) says he has good races with n/a Rex's on the highway alll the time he only realy starts to pull away over 195Kph.

BTW just curious what u guys think the 197KM dead engine car is worth, cause Im gonna make him an offer.

Thanx again.

 

BTW, my engine replacing friends say they can get Jap spec motors for just about any car, does anyone know if there is a preformance difference between them and if so what and how much?

Thanx Again

Ok hold on a second.
1. If the car is using that much oil then it is NOT worth 1500, you should try to talk him way down, so as to save money for a rebuild kit or a J-Spec T2. If you make an offer do not go Above 900, in fact, try your best to stay well below it

2. It is perfectly possible to swap the motor with a T2 motor(an 87-88 T2 would be easiest) WITHOUT converting the drivetrain. Kabooski has done it and I am in the process myself. To do this you only need the following

1. J-spec turbo motor
2. T2 wiring harness
3. T2 ECU
4. T2 boost sensor
5. T2 solenoid resistor
6. T2 A/F meter
7. T2 Accelerator cable
8. T2 hood(optional, stock intercooler will fit under N/A hood)
9. You will need to switch the N/A flywheel and rear counterweight onto the T2 motor.
10. You will also need a downpipe to connect to the stock N/A exhaust(from rx7.com or racing beat)
11. An N/A clutch as well(whenever you pull a motor it is recommended that you replace the clutch components)

 

That sounds like a nice car, but you should decide now if you want a turbo model or not. It is not easy or cheap to convert a non-turbo car into a turbocharged car, and you would be better off just buying a TII if you wanted to go this route. I recommend starting with the non-turbo model as it is much easier to maintain, and is a good primer to get you started in the rotary world. The 5-lug wheels are the way to go, and an aluminum hood is a plus, but be sure to stay away from the dreaded automatic transmission. I wouldn't bother with an engine compression check as the seals are obviously shot. You should still consider taking it to an RX-7 shop for a check-up. Here is a web page which lists things to look for when buying an RX-7:

When the seals go, the engine needs to be rebuilt, not necessarily replaced. You may want to price an engine rebuild at your local rotary engine shops, which is probably going to cost about $3,200 CAD. Yes, this is a lot of money, but the seals will most likely last another 200,000Km. I think that the price of the car is low enough where an engine rebuild is reasonable, especially if you can get it for $1000-1200 CAD. Were the engine fully rebuilt, and the rest of the car in excellent shape, the Blue Book value would be around $4,500 CAD.

There are plenty of mods available for an RX-7, and I have known people to spend over $80,000 CAD on their non-turbo RX-7. You can start off your mods with much less of an investment by getting a high-flow air filter. If you buy a car that needs an engine rebuild, then you can get it street-ported during the rebuild for an additional $350 CAD or so. As parts gradually wear down (exhaust, clutch, flywheel, shocks & springs, etc.), you can replace them with better performance parts.

 

I agree with BigWoogie. If its burning that much oil it needs rebuilt. Nothing else will help it. Don't go over $800-900 and thats only if the interior/exterior is in good shape.

 

ive got all the parts for the swap... PM if your intrested...

 

Just so that everyone is on the same terms, $1 Canadian = $0.62 US.

 

Yes our currancy is amazingly less valubale, but after exchange bank fees etc. the exchange is closer to .50, so the $1500CDN is like $1000USD

 

IMO, you would save yourself alot of money, time and grief just buying a Turbo.
First of all if you've driven Turbo Supras you're going to be very disappointed with the stright line performance of an NA. If you decide to throw in a TII engine you'll spend a bunch of time and money getting the parts, and the car will be off the road for weeks if not months (I presume you're working to pay for all this) while you do the work. If you decide to stick with the NA drivetrain, you then limit your scope for future engine mods, because these things will fail at lower power levels than the TII ones.
You may spend a little more money initially, but consider it an investment. It's less money (and a lot less time) than you'll spend converting an NA.
BTW, with the intercooler in its stock location, the TII bonnet is not optional.

 

Its quite true that the Supra Turbo is a (inserrt mild profanity here) quick car, however the Car I drive for work is a 94 4cyl auto Cavalier Wagon, that has 240K on it and is...., well a slug at best. My other car is a 88 mazda 323 manual 4spd SOHC, 82Hp of furry a fun car to boot about in but its not a sports car, it currently needs a new B6 engine. This is my wifes car and I have to fix it for her.

Anyway I'll keep the car NA, I don't need a turbo (although I would like it) I just need something that resembles quick. The reason I was interested in upgrading the engine is I have a very limited budget (Yes I do have a job, just bills, bills, bills, mortgae, and more bills). I plan it to be a project car I hope maybe to have running before the end of the summer, but I cant afford the output to buy a Turbo or Turbo II, but a slow investment of time and money I think I can muster.

Maybe eventually it will become my wifes car and I can get a Turbo or Turbo II, and then one day a FD3S

Anyway thanxs for your input.

 

If I could afford film, camera, and a scanner(or money to go to kinkos) I would gladly show you a picture to prove that statement incorrect, but the conversion I just listed (with the addition of a Majestic T04e to that list) has drained my pockets for the next 2 months, so if I dont have a FMIC by then, stay tuned for some pics............

 

You don't even need the cpu!!!!! You can run at 7psi safely on an n/a cpu (I do everyday). All you need is 84-85 gsl-se injectors on the secondaries, a TII intake manifold (It will work on 6-port mine is 6-port). You can use your engine and have to make no other changes. Slap the engine in and spend the rest of the money in wheels!!!! LOL

 

Ok so did u put a turbo on your n/a engine or put a turbo engine in your n/a car, and if u put the turbo engine in your car why change the injectors?

And the computer runs 7psi fine, what did u have to do to the wireing harness?

sounds most inteiging! please tell me more!
