like it says, how much boost is safe for 88TII?? stock everything..just wonder..

don't exceed stock boost (6.5psi) otherwise you'll hit fuel cut and be fooked.

How about stock levels? The stock car is made to be stock. When you start modding your car, you can't just do one thing. You must upgrade several components just to see one change.

Well if everythings STOCK, only STOCK levels are safe

how would you increase boost levels without changing anything anyways? j/k

well, so what should i do 1ST?? what would u do 1st??

well, after a full tuneup (plugs, wires, fluids, check'd the PD or bypassed it alltogether)

depends on how you want to mod

to do it right, first replace all the worn parts, this while take you a while, you car is 15 years old hense 75% of your car is worn, but you dont have to do this

if your just looking for power, get an Fuel cut defender, then buy some free flowing exhaust and construct an intake, that will give you some nice power

by the time you do all this, you should beable to decide on the direction you wish to mod, and probly wont have to ask "what to do"

seriously though, check your pulsationdamper, dont feel like reading another thread on how someones car burnt to the ground again

in order to see more boost you need to free up your intake and exuast systems, free flowing exaust and such. Once this is accomplished start with getting a fuel cut defender (FCD), upgrade your fuel system, then upgrade your injectors to handle the excess levels of boost. But most importantly you have to get a controller for all this ie like either a fuel controller, boost controller, or prefrably a new engine manegment system.
At this point you looking at like a good 1500 bucks or so. If you do these mods seperatly and race the car without worrying about these other systems you can destroy your engine. So my friend the moral to this story BOOST SAFELY!!!
Good luck
corse this is what id do/will do id do your own research also.

well, i got an engine here that i'm waitting to be ready to put in, mild street port with windowed and grove oil thinky i forgot how it called..PS: i know this guy from Panama that been working on rotaries like 20 years now.. he own a junkyard and also just finish building AN R100 with Carburator ( nice looking) will post pics soon.
the reason i'm here is i also want to learn some for my self and beready for this engine before i put it in..like what i should do ...i'm use to play with Nissan but new with rotary..

RylAssassin

Ok cool well theres a lot to learn
First off what year rx7 is this? What is the condition? Like Crackhead mel pointed out most importantly you need to make sure this car is running well before you start modding. Its common sense
Then considering the first upgrade which should be your exaust/intake you should know that rotaries respond extremly well to these upgrades you can get a lot of power out of them. Just let us know what you would like to know and we can help you out as much as possible. Theres so much info in here about these cars its insane you can always use the search feature in here to find spacific topics if ya need.

i agree, make sure everything in the car is top notch. if it's broken, dont' replace it with stock, put something better in there, unless it compromises the rest of the system (i.e. added boost when there's nothing to compensate). the pulsation damper is a good place to start. replace all vacuum hoses with a silicone kit, replace all fluids and check your cooling system. the downpipe and precat are known to create alot of extra heat, so replacing that would be a good idea, or simply gutting the precat (it only functions on cold starts anyways), but it will increase boost.
most of your problems will come from increased boost, so getting a fuel system capable of handling the boost is a must. now there are many different ways of doing this. when you do any mods to the exhaust or intake boost skyrockets so you can either add slightly larger, 720cc injectors, fcd, and a s-afc along with walbro (s-afc won't control anything over 720), or do the same fuel setup, and go full standalone (haltech, microtech, tecII/III, etc.). full standalone is the safest, but most expensive route to follow; it will allow much more control over the system. this isn't set in stone, as there are many options open as to the exact setup you wish to use, but if done correctly and safely, intake, dp, freeflow cat, and exhaust will see a good hp gain. oh, i almost forgot, PORT YOUR WASTEGATE. the s4 gates are tiny and easily get overrun by excess boost created by the exhaust and intake mods. you WILL see boost creep after these mods. you could also upgrade to a s5 turbo which flows a little better and has a better wastegate. there are lots of things that keep popping into my head in no particular order so i'm sorry for confusing you. i've got a link around here somewhere about a staged upgrade path which is both safe, and power-producing. also, a good electrical boost gauge is necessary. it will read more accurately than a mechanical one because it gets the same info the ecu sees. umm, turbo time is a smart addition, probably should be the first mod along with the boost gauge. let me find that link for you, that should clear things up a bit. anyway, just treat her real nice and she'll do the same for you.

check out boostd7's post towards the bottom of the page. it's lengthy but it helps alot. it was in the 2nd gen archives, along with lots of other useful information. if you're brand new to these cars, i'd go through there and read as much as you can, the threads are archived for a reason. hope this helped,
