What power can make t-78 with :
street potring - 2mm new seals stock
fmic greddy
koyo radiator
3 inch full exhaust
twin power hks
850 cc- 1300cc
sard fuel pump + external Bosch
sard fuel reg
magnecor 16 bit wires
PFC
For 1.15 bar of boost ???

 

Some one with approximatly these mods ?

 

look at the rx7store.com web sit jason says he making 506 at 19psi

 

how much power and at what boost are you making tony? how do you like it?

 

19 psi = 1.3 bar . I think with 1.1 more than 400hp . What do you believe guys ?

 

HOW LONG WILL IT LAST. THAT THE ?

 

ok lets take bets on how long it will last. it will be tuned at 15psi stock motor . the car has 79,881 miles on the car . place your bets .

 

ok d has tuned the car. and high boost is 18 psi and 14 on pump gas. i had put over 3k on my car soo far . it runs strong very strong . cant wait till i tune it for 26 psi if it blows it blows . extra thanks to d and the rx7 store

 

apex seals start to get brittle around 50K miles and become much more weak than new out of the box seals. No one can tell you how long your engine will last but I'm going to go out on a limb and tell you with a T78 @15psi with a engine that could have as many as 78K miles your in the danger area. There are bone stock 7's that dont last to 80K miles.

Also, I'd take the advice someone else gave you and have the engine rebuilt now, before it blows up. Once it blows up its going to send a apex seal thru the turbine wheel of your new T78 and its going to be rebuild time for the engine AND the turbo.

i doubt your motor has 79k on it. you should have had D do a compression test so you can guess the condition. If its the stock motor hold on buddy

 

The compression wont matter. 3rd gens never go bad due to wear of the seals, like a n/a rx7 does (150K miles). The prob is when they get over 50K miles the seals start to get brittle and they crack easier.

 

well did you ever think about that if it has low compression then it may be old and he can tell if its going to crack soon since he doesnt know the real mileage? If it had nice compression then theres a chance it could have been rebuilt and the seals arent brittle.

 

if it blows it blows i dont care then its time to put a t 88 with a bad **** port in so lets blow it

 

im glad money isnt an issue with you, lol. Mine didnt last too long afte the single turbo install. Of course there was other reasons for that. Stupid fuel injector. I only had about 7k miles on it.

 

why doesnt he know the mileage, what did i miss?

 

for the past mounth i have been running 15psi on pump and c16 24psi still running strong . iam doing this to see how long this engien will last .

 

If properly tuned and maintained it may last longer than you think. Just ask Ernie T about this (what was he running 26-28 psi?)

T88 = Sir Lag-a-lot, Lagmaster 3000, the Leg-o-matic
Why not get a newer turbocharger that can not only spool up sooner, but make more power as well.

 

Look at the rx7store.net web site, jason says he making 506 at 19psi

 

ernie got beat buy poor boy in his honda civic in baltimore .

 

Ernie got beat running 13psi on his car caring a passenger. Poor boys civic has never seen a 10sec time in it life. Just ask civic boy, he will tell you he would not race ernie on race gas with the boost turned up.

 

why he do that to him self

 

did you ever race him

 

Your half to be joking. If you were him would you want to race a car that was 3sec faster then you I don't want to discuss this online I just wanted to prevent you from spreading rumors when you don't have all the details.

 

My point is that the seals being brittle doesnt lower the compression. It could have 90K miles and perfect compression with extremely brittle seals. You turn the boost up and its gone.

The compression doesnt tell you how much longer the engine's going to last.

Even at the lowest mileage he listed (48K miles) thats pushing it with a T78 and high boost

Whats wrong D, you don't think it would be a close race if you whipped out your 7
