rx7male I just read all your posts in the first gen section here and all the your posts in the 2nd gen section and all I have to say is I am sorry nobody is reading your posts. More then half the comments here was useless info because you where right in the beginning. You have a MS and all you have to do is do what ever set up works and check to see if your running lean with a wide band and your MS which you where going to do anyway. So do it and see if you run lean...and if you do then do what everyone said, bigger injectors and if that’s not enough then better fuel pump and so on to get enough fuel to where you want to boost to. It also seems nobody knows what you can boost max. I say dotn go above 8 but I am pulling that number out of my ***, but that’s what I feel is safe for you.

 

sorry TurboSE your post made sense and helped him out...


and if all of this makes no sense then its because im pretty fucked up right now.

 

I know man! i know!!!

 

and hes right! My motor handled 7/8 PSI w/ the stock Fuel pump and (Aftermarket FPR) Just make sure to mount Your I/C in the front.....Cold air=More fuel= less knocking /pining/detonation

 

so i dont need to upgrade my fuel pump? but i will need a Fuel pessure reg? which will be cheaper? a fuel pump or a FPR? let me know thanks

Cory

 

Just get a Fuel pump.....since you are allready getting The S4 TII fuel rail.
fuel pumps are Under $100 or close

 

nooo... lol what one should i get?

 

You can run 10 psi pretty safely. I would Highly recommend a fuel pump.

 

if you want us to choos for you then get the walbro fuel pump that every one is always talking about

 

woooooo dude I wasn't refering to you.... Chill-out, and last thing i need is a megasquirt lesson; thanks though! ha ha haaaa, lol. You sound like you know yer stuff. Just others new to the wankle world kinda get to me sometimes when they offer up opinions with out vaid experiance, or knowledge.

 

Leave the 680's in the center iron(primaries) and get Bigger injectors 4 the secondaries or at least another pair Of 680's
460 seems kinda low(remember You are Boosting a High compression motor)

 

sorry bud... lol thought you were talking to me... yea i know some stuff... not all as you can see from some of my posts... lol

BUT... when you are below a certain RPM range you are normally running rich and thats with thbe 680s so wouldnt the 460 be good... to lean it out a little and then tell the MS to kick in the secondaries (680cc) at like 3000-4000 rpm... so that the car doesnt lean out totally... like that would be a total of ~1140ccs of fuel in the higher range of the RPM scale... and that should be enough fuel for 5 psi... correct? correct me if i'm wrong... cuz i will admit it when i am... this is just the way i see it... but if theres a better set up... i'm all ears... lol

thanks again guys
Cory

 

NVM! I 4got about the megasquirt............U'll be fine!
ONLY 5 PSI? You'll want a little more then that! TRUST ME!

 

lol yea but i dont wanna pop my apex seal... lol thats why i'm only boosting 5lbs... and besides i wasnt doing this for power... lol if i were i woiuld have swapped in a T2 engine... nah doing this for originality... like how many SE engines do you see turboed! lol he he cant wait... anyone else wanna add some info that would be great... and thanks to you all who have helped me so far with my questions!

Cory

 

You not doing this 4 power? Well after U drive your car w/ 5psi and a BLOW OFF VALVE .....You will Like it! it's a FAt difference and TRUST ME ON THIS You Will WANT MORE

 

lol you may be right... but i would like to keep my engine for years to come soo... lol i think i'll keep the boost down... lol i know i'll want to turn it up... but dont forget the stock s4 turbo can only give out so much boost so... thats another reason as to why i bought it so i cant go over to much boost... lol he he arent i smart... lol NOT!

Cory

 

the stock s4 turbo can put out 14lbs fine if you keep the oil and coolant lines on it and have a front mount just so you know

 

wow really... thats sweet... to bad i didnt want to know that!! lol grr you for giving me more ideas

 

just for more info because I seem to like to post in your thread a lot of people say not to go over 12 psi on the turbo unless you have a large front mount. It can handle 14 and even 15 for some people but it gets so hot that you can often see a loss in HP due to the heat generated unless you have a good IC. This is just what I have read by a few people on the forum that I feel know what they are talking about

My Current setup..Cartech FMIC/2"IC aluminum piping/Garrett t3/t4 turbo/2 1/2" exhaust/Cartech (deltagate) wastegate w/5psi spring/Walbro 255 fuel pump/ Cartech 2025 FMU/Currently boosting 5psi on the stock ECU!!! @ 170rwhp on a 150k mile 13b (Yes the bottle neck AFM is still in there)
Yes this can be done and I have been running this setup for over a year. The thing about this forum is everyone has theories and while reading they believe. There is about a hand full of peepz on the FB forum that are acutally boosting, take advice from these people. I've found when people started a turbo project on this forum everyone pushed them to buy a T2 motor and do a swap rather than trying to help them. I know by personal experince the project is not easy you will have to fabricate parts to make it work but try to stay on track and dont get rediculis on trying to get 14psi right off the bat, work up to this level and you wil learn soo much more. On the GSL-SE motor you shouldnt run anything over 12psi after it is fully built. This is a high compression motor so running 5psi is like running 7 or 8 on a T2 motor. Once you start pulling 5 pounds you will be happy, then once you hook a boost controller and put it up to 7 you will be even more please.
Another misconception is the exhaust you do NOT need anything larger than a 2 1/2" exhaust this supports over 300-400rwhp qouted from Corky Bell. Directfreak has a nice exhaust setup with the two Magnaflows, but you would only need this in a 2 1/2" version.
As far as you switching the upper and lower intake to me makes no sense. Why keep the SE block and change everything else around it? I didnt really read this thread through seeings I noticed people just throwing you garbage, so I am not quite sure what your goals are with how much hp you are wanting and what the car is going to be used for. I can say I built mine for the street with reliability in mind the whole way.
As far as the question on which FPR/FMU you need can only lead to you need one that is boost dependent. Meaning for every pound of boost it will add fuel. There are FMUs that you can varry the onset meaning for every pound of boost you can change it to 1psi of fuel to 12psi of fuel. The Cartech 2025 allows you to do just that. Basicly how this works like the same as a boost controller it is a bleed in the line. I will stop rambling here, if you have more question just post them up hopefully someone will give you some useful information.

Have fun ;]

what exhaust mani are you using r0taryluv

 

Actually I bought the turbo and the manifold together...it looks simular to the Cartech manifold. It is mainly for a smaller turbo, couldnt bolt a larger T4 compressor on it due to clearence of the intake manifold.
