Ok, I got a few questions for some of you out there. I have a 1990 GTU with the N/A engine. Everything in the car looks bone stock, except for the radio and stuff like that, under the hood no visible modifications. I had it dynoed about 8 months ago and it dynoed at 251hp, I have taken it to Rocky Mountain Raceway and with perfect shifts i ran the 1/4mile in 13.1 I have been trying to figure this out, someone told me maybe my ECU got reflashed and a possible port and new injectors. I havent really torn into it to much because it works great and i want it to stay that way. But does anyone know why my car would push that much horsepower? any suggestions?

 

are you 100% is n/a?
Also is the dyno 251 bhp or whp?

 

he said he took it to rocky raceway 1/4 and hit 13.1 ...so it had to be whp

but i can be wrong i kno my t2 probably wont hit 13.1 ...any pics of the engine bay.?

and yes like "brody" said you sure its an NA?

 

Yeah im sure 100% its an N/A, its something that has baffled alot of my friends who have rx7's as well. so thats why im asking everyone. And no pics of the engine bay, but I could hopefully take some and get them uploaded soon. And it is 251whp

 

must be internals...
im guess cause your only looking whats outside.

 

It's turbocharged, or a three rotor.

Or bridgeported, which should be obvious from the idle.

No way a NA 13B will ever hit 250 RWHP without at least a healthy full bridgeport.

 

13 seconds is really fast..
there is gotta be something under that hood thats making it fast

 

An LS1 under the hood is not "bone stock".

 

Pic of timeslip or GTFO.

 

Well whatever it is, let us know so we can do the same!

Interesting. It has to be some kind of ridiculous port, but you'd be able to tell if it was...

Add the dyno graph to it while you're at it.

I'm guessing its bridgeported.

 

I guessing it is running on “hopes and dreams”

 

lol.

I'm banking on the fact that this guy is smart enough to know for sure it's not a 20b or boosted. That fact remains to be proven.

 

no reply from thread poster?
wtf is up with that?
proof pls?

 

Sorry people, i havent got on..ive been sick as hell, im waiting for my friend to come over so i can take video and pictures with his camera

 

Please do that, there has got to be a reason for those kinda numbers, and no one will think other wise until proof is given one way or the other.

 

Where you located in Ogden? I could come by and take a look.

 

im in taylor, in between west haven and hooper. I have looked for the dyno paper or the timeslip from rocky mountain race way but i cant the papers since its been over 8 months sence it was done. some people told me that maybe the dyno was off, so im starting to believe that.

 

Someone for got to say IT...Yes...IT!!..this thread is Worthless ..Without......................................... ...............................................Pic s!...(chuckle..GTU Guy...It's a Running Gag around here so don't be offended!)
