just as a question of curiousity, how much power have some of you put down with a stock turbo II block but other supporting upgrades?, i mean no porting, lmk what you got!

 

You can make plenty of power , s4 just have weaker irons that will crack easier than the thick cast s5.

I'm going for a long term goal of 300whp

I've seen 400+ whp on a stock port block , you just need the right Turbo running high boost,along with all the supporting mods.

my friend was running at around the 380-400hp mark back in the day, stock engine, stock ecu, 60-1 turbo@15psi

 

jesus

 

on the stock ecu? it must of been chipped ?

Rotary > Pistons

 

that sounds over the top

 

yeah since the stock ecu fuel cuts around 8 psi lol

Rotary > Pistons

 

i can believe the power output with supporting mods just because forced induction motors benefit more from mods, but stock ecu, which all of the rotary owners i know swear is crap! ehhh ok.....

 

FCD, manually retard the timing, lot of fuel pump, lots of injector, and lots of fuel pressure.
It's crude and won't pass emissions, but it can be done. But in this day and age, there are far better and safer ways to go about it.

 

yeah definitely will be losing power when in vacuum from the timing being. constantly retarded

i'm sure he had an FCD...

the total mod list was

reman engine
HKS manifold/wg
60-1 turbo
RB turbo back exhaust
HKS AIC with x680cc injectors.
FCD
custom front mount, same sparco core as the FD guys run/ran
some fuel pump, i think.

car ran 12 second 1/4 miles in 1994-1995....

there is another guy who used to be on here, forced7 or something, and he had a similar setup, but he was actually making more power

 

was it a street car or just for racing?

I'd be scared to run 400 HP on my s4 irons

Rotary > Pistons

 

street car.

 

id have to see slips

 

from 1994? you need a time machine.

 

i understand that sir im just saying especially when the automotive industry had nowhere near the knowledge they have now, just hard for me to believe without documentation

 

there is, just not on this forum, as it wasn't around at the time. you might Email ReTed, or actually i saw paul last weekend.

the other fast guy was here, he sold the car before the Rx7 forum, but its in the sig, https://www.rx7club.com/single-turbo...t-track-64299/

there are lots of fast cars built before the forum, one of my favorites is this 180mph on the straights in 1937...
