Thank you for posting that. The only real way to tell if you gained anything for the ECU upgrade and for that matter any performance parts is to dyno your car stock and get a/f ratios and also dyno after each mod. I didn't dyno before my ECU upgrade. My mistake. I gained loads of Torque but lossed loads of Hp because of the automatic transmission. You loose like 20%-25% due to drivetrain loss.

 

wait what? I will lose HP if I go with the ecu upgrade??? I have an automatic.

 

I lossed Hp. I'm not saying you will, but there is a chance that you will because of the drivetrain loss issue.

Not to mention I wasn't at STAGE ZERO at the time either. You will still get a great kick in the but though with an ECU upgrade that is for sure.

 

damn now I cant decide between, reversed intercooler upgrade or ecu upgrade.

 

I also have a 98 GLT and was interested in putting a BOV on it. I have heard of the car's RPM's sometimes drop low enough to almost stall the car when the BOV goes off since it is not providing enough air into the throttle body. Is this true? Have you had any problems like this?

 

No I haven't had any problems like this.

 

is it possible to have 15g turbo on 98 s70glt?

 

yes, i think thats what the s70 T-5's come stock with, which is why they are faster.

 

the thing is when i took my turbocharger out from my 1998 s70 glt, it said 15 g on it, im gonna take a look at it again. hmmmm

 

how much psi do stock s 70- t5 run?

 

well I am not sure, but I think its like 12-15psi

 

are you 100% sure that t-5's came with 15g turbos?

 

hey, i know that my s70 has 2nd engine in it, not the original one, the previous owner told me that. AndI have 15g turbocharger, probably i have engine from 850 t5.

 

possibly, or maybe your lucky enough to have a s70 t5 engine.

 

ya might be.... also, do you know whats the difference when it says 13g and 13t on mitsubishi turbines? and 15t and 15g? why they put g and t? what does t and g stand for?

 

afraid I am not that technical, sorry, I only know what I had talked with s70driver about in my thread o' questions. But ill google it.

I know this probably doesn't help.

 

thanks for link its interesting to see different turbos and i see now that 850 t5's came with 15g turbo.

 

13 = size inducer/exducers "B,C,G,T etc... are the specific inducer/exdcer blades. Later is newer.

13G = 375CFM, inducer = 1.580" exducer = 2.000"
13T = 445CFM, inducer = 1.597" exducer = 2.203"

I am not aware of a 15t, there is a 16t, which would be better than a 15g

 

thanks you very much. nice 3000gt, people say they heavy tho, i dont know, but I guess 3 liter and twins make up for it.
