So i'm about to undergo the SE to Turbo 2 conversion & I had a couple of question. One of them being, would 285rwhp be a goal to aim for for this conversion?

The person who had this car didn't exactly take care of it so i'd prefer not to push it's limits. It's still got to stay in the reliable mark till I buy another car(Turbo 2).

I'm doing the conversion the right way(motor, tranny, rear end, drive shaft, etc...) I would like to see at least 300 coming from the & I figure that 285 should be a good place for this conversion.

Up to what horsepower would the stock intercooler still be effective?
I know theres someone on this forum thats running a T60-1 Turbocharger with the stock intercooler in place. Would you all happen to know who it is. If so, how well is the intercooler doing it's job?

Can the stock turbo be spun to 285hp or should I consider an aftermarket one. If so, what one would you all recommend?

Lastly, what would be some of the things that you all would recommend for me to get to do this conversion.

Where you doing this at Fuego's?

your not going to get no wheres near 300 HP on a FCD and stock computer
you need to spend another 1500 for a MicroTech installed and tuned
and at least a "complete" Hybrid that Fuego does (P trim) full 3" exhuast, FMIC etc. etc. etc

In other workds get ready to spend some $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
and you best not have it as your only mode of transportation after Mody'ing it
or your going to find your self catching the Lynx bus

180 to the wheels should be the goal with some BPU mods

Good Luck
It's Nice to Dream

Nah, I was going to install the major piece with a friend of mine then have the Turbo 2 harness & ecu done by Ortig Racing. Well damn, thanks for taking that bad boy down with the shot gun....I plan on doing the setup right regardless, if it takes an ecu upgrade(which is common) then so be it. Please, I know im new to the rotary world. But don't be an a**hole about it.

I'm here to learn, if you'd prefer not to help/teach. Don't shoot down my goal. Just do like most & look at the thred then move on with no comment. I'm trying to get ideas not have all mine shot down.

I disagree with Kabooski, a lot of Japanese Tuners take the stock ECU up that high by using additional injectors. This isn't very common in the states, but I think I'm gonna give it a shot.

i think you can achieve 285...... hes right on saying its gonna take time and money..... the stock turbo wont get you there, niether will the intercooler.... to my knowledge, youll need......
-upgraded turbo (t04-e turbo should be sufficient)
-fuel cut defensor (hks, greddy, rx7.com)
-at least 720cc injectors (secondaries)
-boost controller (ex. apexi avc-r)
-air fuel controller (ex. apexi s-afc 2)
-front mount intercooler (greddy, hks, custom)
- intake (custom)
-3" turbo back exhaust (racing beat, custom)
- blow off valve ex. apexi twin chamber bov)
- possible rebuilt "built" motor to withstand 15- 20 lbs of boost (pinned, ect...)

if anyone can add to this list, please do

kabooski

yea yea but trust me

I check the for sale section and know every rotary shop in CF and SF
people get into it spending all this money and time and when the motor breaks

Next post is "For Sale"

Do not get into these cars and have it be your only mode of transportation
Like he's saying he wants his to be.....big mistake
even the best tuners and builders can not keep a high HP Rotary from breaking

Not Steve Kan
Not ABel
Not siguel
no one

be prepared for it
its a labor of love keep that in mind

I love working on my own car and love rotaries since I was 16
but that is the name of the game

I went stock for my turbo conversion.

With no boost controller I am doing 160 to the wheels with 7-9psi.

If you are going to keep the stock ECU then I recommend the Rtek v1.7.
It stock uses 720's in the secondaries.
It also remove the FCD.

That way you can either tune for 720's and go for like 200hp or you can add bigger injectors in and use an SAFC to tune them down to usuable ranges.

The Rtek allows you to use 12psi reliably on it's new fuel maps.

Before you open up your exhaust and run a full, 3 inch turbo-back exhaust system, I would recommend a couple things to do to decrease the risks of something going wrong. Most people who mod their cars tend to get rid of their emissions equipment as well, and it might be a good way for you to simplify things in your engine compartment. Whether you do get rid of these things though, it would be a good idea to replace all vacuum hoses with good quality silicone hose.

Here's a relatively safe way of proceeding with this conversion (it is in order, hence the numbers):

1) Get a TII fuel pump, rewire the fuel pump, get new fuel filter, replace old rubber fuel hoses, and send your injectors out to get cleaned/balanced in one interval.
2) Replace spark plugs with all trailing plugs (9's) since you will be upping the output of the engine considerably, and maybe get new spark plug wires.
3) Clean throttle body, as they tend to stick often times. Might also be a good chance to do the throttle body mod (search for info regarding that).
4) Get an intake which replaces your old TID with a smooth mandrel bend TID.
5) Port wastegate passage(s)

That's as much as I will suggest regarding a tried and true "safe" set-up. It will net you about a 1-3psi increase in boost (your boost should read 5-6psi depending on how well you've ported the wastegate (remember, goal is to keep boost as close to 5psi as possible, since that is the rate of the spring within the wastegate), and probably get you closer to 160-180rwhp depending on how old and clogged your old exhaust is. From here, there are several options you can take to remain somewhere near the "safe" zone. However, there are so many options regarding exhaust setup:

1) Stock precat ~> stock cat ~> aftermarket cat-back
2) Stock precat ~> high-flow cat ~> stock cat-back
3) Stock precat ~> straight through or presilencer ~> stock catback
4) Downpipe ~> stock cat ~> stock or aftermarket cat-back
5) Downpipe ~> high-flow cat ~> stock cat-back

Any other combo could push the limits of the fuel system. Your boost should not get any higher than 10psi with anything above that I have typed so far... If it is higher, then you either have not ported the wastegate passage(s), or you didn't port it well-enough (to my definition/standard). You should see around 180-210rwhp with everything so far.

Some people may like to push it a little further than me, but I believe what I have just typed should be consistent and reliable for anyone with a TII.

But remember say you spend 6 or 7 thousand on a car doing this you got a damn good car for the money .It sounds like alot of money but its not for what you get .

i did my conversion, and was boosting at 8psi and was a bat outa hell. Of course i had free flowing exhaust and the tb mod and a custom pipe for intake causing me to boost at 12psi and blew my motor just make sure u get a FCD, cuz i didnt and now im getting a new motor.

Good luck with ur swap. Good times.

Thanks for the help people. I was going to replace the exhaust right off the bat with a complete unit from Racing Beat(downpipe back). Thanks Infini IV, thats the info I was looking for & thanks Viper that the info I was looking for for after the rebuild.

I was thinking about sending it to Kevin @ Rotary Ressurrection. Unless someone knows of a better place(no offence Kevin). I was thinking about Pineapple(Warrenties work wonders)
After the performance rebuild is when all the heavy mods will begin(after the break in period anyway). But, before that, I just want it to be reliable. Hell, i'm happy I drive an RX-7 as it is. It makes for a nice chat topic.

I'll keep you all posted on how it goes though. Thanks for the help & anymore info that can be produced will be welcomed.

Before I cut out, believe me Kabooski. After the rebuild, a new car will be sourced. Something that is really dependable. So don't worry I know about the hi-boost Rotaries and their gremlins. I'm not an idiot...well completly anyway.
