I heard this from one of my friends that i cruize with and he knows quite a bit about cars... i was just wondering if it is true??
Thanx

 

youll have to be more specific in your question... for example a n/a running how much boost? what turbo? so who knows.... but not to start a war or anything but a stock s5 turbo on a stock n/a block boosting around 10-12 will put a new ******* in a STOCK turbo II .... your talking about 2 seconds faster in the quarter mile....

search theres plenty of information on this along with people saying how fast they are

 

T4 Kit 60-1 Mazda RX-7 Turbo Kit

 

assuming it is doen right, it will kick the TII's ***. a T4 is a much better turbo than stock, and the higher compression is worth quite a bit of power.

 

thant is what i was looking for...thanks

 

but....btw... any idea how much horse i will have???? with intake and exhaust??

 

FYI a properly modified NA RX-7 will beat a stock TII, even without a turbo.

If it's one of those cheap Ebay kits, it will self-destruct, and then the NA RX-7 will be MUCH slower than a stock TII, lol. Also, keep in mind that turbo kits do not include fuel upgrades, downpipe, fuel computer, BOV, intercooler, and other items that you would want to install along with the turbo.

Too much speculation. See dyno charts here:

dosent n/a mean natural asperation??? so dont you mean a n/a rx-7 beat a t2, prolly not unless the n/a wasnt stock

 

It depends on the modifications done to each car. If you put basically the 'exact' same mods on, the 6port would be quicker. (Again, depends on how it's installed)

 

why would you really only want to do 2-3, obviously you dont know what the hell your talking about.

 

well he said stock t2 but he didnt say stock n/a,also was i right about the n/a thing

 

No, not really. What he's talking about is an N/A engine with a turbo bolted to it.

 

Problem is, you're going to have to do so much custom work to fit that turbo on there, not to mention you'll probably blow it up within a week.

 

Supposedly the 6 port higher comp. motor is worth more power if turbo'd but yeah like sonic rat said, you probably will blow it winthin a week, unless your running like 6 psi...but who wants to run that little?

 

The N/A exhaust pulses are AWESOME to power a turbo. But being a non-turbo engine, it wont hold upto the same boost unless its built properly internally.

 

I really wish people would stop posting crap like that.

I ran my car at 8-12 PSI for 10K miles, before I decided to tear it apart and make some real power. Others have put much more mileage on their turbo NAs. When I tore my engine down, there was NO turbo related damage. In fact, the internals, save for worn apex seal recesses (this was an engine with 260K on it, after all) were mint.

Obviously, you have absolutely no experience with what you are posting.

 

How much horsepower do you get off 8 - 12 psi of boost? ANy aftermarket kit recommendation for a '8513B?

 

Power depends on a lot of things. 8-12 is a large range. At the higher end, it was enough.

There are NO aftermarket turbo kits designed for the 13B NA. You have to make your own.

 

I guess you missed where he said he was going to use a T4 60-1? Chances are with that turbo, anything higher than 6psi and the owner isn't going to have much for mods to support it and blow it up, which is what I said, and what the guy agreed with me on.

 

I'll be changing that shortly!

 

That's really similar to, if not exactly, what I plan to be running soon...Of course, I'll have the fuel system to support it, so...

 

so,sonicrat, your kit is going to be based on the stock tII turbo correct?

 

So...basically what are you guys trying to say???? are you saying that it is a bad idea to get that turbo? well.. then which 1 would you buy?

Basically... i want to turbo or supercharge my 91 N/A...does ne 1 have any recomondations on what i should do??? or that turbo/ supercharger i should get????

 

Check out SonicRat's thread called "Interest in 6port N/A turbo kits." He's creating a turbo kit for the NA cars and will be selling it shortly. I would wait for that instead of making a custom turbo installation on your own.

 

i have a TII block with NA compression rotors, i run 12 psi on a T4 right now, with stock IC and 89 octane gas. i will be switching to a fmic soon and running 15 psi.

i have 15k miles on this engine so far, hasnt blown yet. i think people underestimate the durability of the 13B.
