S4/S5 rally hodgepodge FC build
Well the old s4 streetported motor blew on me, cracked aluminum housing at the spark plug holes and broken motor mount, oh and busted exhaust insert on the rear rotor prob didn't help.
a 100k millage s5 NA motor is going it, but with a little goodies and simplicity mods
so I got time this winter and **** is gettin done... slowly
some teasers
I had to sell my awesomely ported throttle body that I did last year to buy this engine so I am porting a new one and plan to make a more improved design and flow test it to see if it is better or not.
Things that have been sandblasted and painted:
UIM
MIM
LIM
water pump housing
water pump
filler neck
coolant elbow
I might do the TB too but I don't want to disassemble it, but I might to modifying the throttle plates and grind down those screws that are sticking out in the shaft for better flow.
Its going to look pretty spiffy when its all together.
Got some work done, getting the engine bay ready for cleaning and rattle can whiteness for matching sake.
My "work space" up at school
just ordered some gaskets now I just need to pick up a few little things and get my injectors rebuilt and it will be good to go by spring.
click to enlarge
I got pan baffle coming along with the gaskets.
after the injectors are rebuilt I need some pineapple racing inserts, banzai OMP block off kit, mounts (mazda competition engine/trans) and an S5 rear auto counterweight and this thing is as good as driveable again!
next week I plan on dropping the trans, cleaning it and giving it an rtv gasket where all the 3 sections meet up because I got a slow leak or seepage thats just going to collect dirt like nobodies business.

wow. way to feel sorry for yourself buddy. your dropping a S5 engine into your car...not really exciting or original.
ok, you've painted your intake manifold, they look nice...we'll see how long the paint holds up.
and at 100K maybe you should think about a rebuild while it's out?
your "ported" TB doesn't look ported at all. looks like you just removed the secondary butterfly flaps.
THAT is a ported tb that I did many years ago.

who gives a **** how long the paint holds up, the engine bay is gonna get dirty anyways. notice how the paint is partly scratched off on the UIM, TEASER. since it can give you a glimpse on whats to come.
and if I had the money to rebuild it I would have rebuilt my s4 streetported motor using s5 rotors, modify e-shaft, go larger streetport or bridge then balance the rotating assembly ( I have access to the tools and equipment necessary )
and lastly, can you not read? It says "teasers" for reason, its not done yet. How much airflow improvement did you gain with your throttle body? hrmm don't know? thats too bad, because I found out before, during, and after for flow results of my work on my previous

oh and your right, I did remove the butterfly valves. If you wanna know why then read that thread above, but reading isn't one of your strong points today...

lol. ouch...retract the claws tough guy.
in case no one has told you, sarcasm gets lost when typing. next time you mean something as a joke, make sure people know that. then you won't get dumb *** responses.
I rather disagree, I'm much rather see a rally car than a drift car. try posting some real pictures of your car in action...or anything else besides an empty engine bay and a random shot of your hood up...like we've never seen those before
yes my screen name is need-a-t2. back in 2002 when i joined I was looking to buy a T2. since then I've owned more turbos than you probably have rx7s, so back the f*ck off, and don't judge people by their screen names.
if the paint is going to come off any ways, which i agree it will, why bother go through the effort of blasting and painting them in the first place? it's just going to look like *** now when half the paint has flaked off. not that it really matters what it looks like because as soon as you start raging on your 100K motor, it won't be long till you have to pull it again
oh and BTW, if you broke a rotor housing you must have been detonating MAJORLY. rotor housings don't just "brake" like that. you might want to think about spending some time tuning your fuel and ignition maps before you go whomping on your sweet ***, stock S5 painted motor. what EMS are you using any ways? I'm guessing a stock ECU with MAYBE an AFC?
gee, maybe you should have noted that, that was the new one your still working on and not the "awesomely ported one". again, things get lost when typing. No I don't have access to a flow bench, so I don't have any numbers for my TB. the whole point of me doing the TB mod, back in 2005 i think, was for better throttle response, so I could give a rats *** how much more it flowed. It did it's job. Nice write up BTW.
and what's with the personal insults, you can't take criticism? your on the wrong forum then buddy.

yes sarcasm gets lots of the internet, **** happens. I don't have any shots of it in action on gravel or anything yet, just the typical sound clip for exhaust and other stupid crap like that, I got links to my youtube in my signature. one of the video shows off one of the roads near me for some hot rx7 on gravel action. I've only had 2 rx7s and one I just bought for parts, so really just one and a half.
you're probably older than me since I'm only 21 so I'm guessing you have a job that pays enough to afford boosted rx7's, I'm on the other end of the income spectrum and just finishing up school so NA is the way to go for me, less down time and more driving fun.
hell yeah I'd love to have a boosted rx7, but that will have to come in my future.
the rotor housing didn't necessarily break per-say, there were 2 small cracks a couple mm long 180 degrees apart when I pulled the motor for flooding and 70-75psi comp. The passenger side motor mount went bad and I didn't notice (but I had a hunch, but by then it was too late) and I think that the vibration from the motor moving around on that busted P side mount caused the exhaust insert to break and that caused a rattling sound, so I comp tested it and pulled the motor. Kinda sucked because the motor ran great, first time at the 1/4 mile track I had run a 15.3 in it with 14" pizza cutter tires and stock suspension, mostly just the RB exhaust and SP. But that over a year and a half ago. If it was detonating bad, from my understanding it would take out both rotors at the same time but when I pulled the rotors, they looked fine and no damage done to them.
I blasted and painted them because I had extra time and assess to the facilities, always wanted to spiffy up under the hood 5 bucks w/o looking ricey . the comp on this 100k motor is about 100, it is in pretty good shape.
I will probably only put 5000 miles tops on that car this year and that won't be 5000 miles of rally racing.
I love how easy it is to pull this motor out, I had to do a clutch job on my friends 1st gen talon TSI (or whatever the AWD turbo one is) and you practically had to remove the engine, that was a bitch. It took like 2 hours to get it ready to be removed then to remove it and clean up everything lol.
for the initial testing and "break in" I am going to be using the stock s4 management system unfortunately, but I have already gotten the sensors that I need to get ready for using a megasquirt II system
and porting the TB I'm sure you noticed the increase throttle response, it really improved my daily driveability, I'm pretty sure that my old thermowax system aged itself to death. But I'm pretty sure I did note that that throttle body was the new one.
I have an S5 TB that I still have to remove the extra butterflys and port/polish the sucka.
