I have an s5 TII block that i just ported and rebuilt. I still dont have everything needed to run the motor turbo. I do however have everything for an NA motor. I was wondering can I put my NA manifolds on the turbo block and just run it like that for break in? I was concerned if the stock NA injectors would be good enough for running the ported motor. Basically what will i need to do to run the TII block NA for a bit.

 

hrm... I would just use the TII manifolds and route the air intake to the other side of the car. You'll have to move your battery... you will also need some sort of exhaust manifold. I think an n/a manifold would work? You are not going to see a lot of power out of this... but really all you need it for is to be driveable.

 

so you think it should be good with stock NA injectors, harness, and ecu? thats how i plan on running it

 

****. it'll run like hell and it'll be sloow. why not just wait?

 

why wouold it like like hell? just wont have all the power, plus who cares about power, its for break in mainly and to make sure everything works fine since ill be running microtech and dont have the stock TII ecu or wiring

 

I havent been driving my rx7 for amost a year now..... how would you feel? i want to drive it so bad

 

I would think, in n/a form, the TII engine should run fine on the 460 injectors.

 

It is street ported though.

 

mild street port? I bet you are still not flowing as much as a 6 port n/a engine. Not the s5 engine at least.

not to mention that the n/a injectors have a LOT of headroom... for the n/a engine.

 

it will be slow. the turboII rotors are lower compression. the fuel maps are going to be off and it'll probably be really rich because of the lower compression.

it would work but it probably wont be worth all the effort. id just wait to get some engine management.

 

Well lets see... right now I have the NPR FMIC, Stage 3 BNR turbo, TurboXS RFL BOV, Walbro 255lph, TII drivetrain, I still need to save up and get Microtech, Racing Beat turbo-back exhuast, make IC pimping, ACT heavy duty clutch, and 780cc injectors for my car to run turbo. That might take about 2-3 months to get.

Exactly how bad will it run and how much slower than a stock NA?

 

i would wait. you are going to get it all together, it wont run right. then you are going to have to tear it all back down. if it was me i would wait. i would clean stuff or fix little tidbits to pass the time. make a nicer car too.

 

Has anyone here ever heard of 4-port 13B's?!?!?!?!

Read up on your history 'wankelheads'....

 

You can't put the intake manafolds from a N/A on a T2, I have almost everything you need for your motor. PM me for info.

 

Heh, quit whining Don't talk to me about not driving your car. I haven't driven my car in 342 days, either (found a receipt the other day for the day it blew up, heh). But I waited to buy everything before instead of ghettofying the parts I had at the time and driving the car like that. And now in a couple more weeks I will be driving it.

If you run N/A mapping on a four port streetported turbo motor, it will idle poorly, get bad gas mileage, and be low on power. You'd have to fabricate some sort of intake for the TII throttle body and intake manifolds, because you can't just bolt up the six-port manifolds to a four port motor. Don't forget you'll have to mount the AFM somewhere until you buy your microtech.

Too much work. Wait a couple more months (like many of us have), then really enjoy your car.

 

Most of us do know what a four port 13B is. What does that have to do with what we're talking about here?

 

he is saying that the 4port wont bold up to a 6port n/a intake. i thought that was a givin and didnt have to be stated. oh well.

 

Well I talked to RETed and Atkins rotary and they both said the engine should run fine with what I want to do. It is a lot of work, but hey thats the same work id have to do when I run my engine turbo. I'm basically just stopping short and running it NA. The car is an 87 NA so the wiring and ecu are already in there. Battery is being relocated to the passanger bin right now, so the MAF can go in that location. Basically like one of you said run the TII intake manifold, and NA exhuast manifold. Hook up the rubber tube with the MAF upto the TII TB. Run the stock NA injectors, and wah la. Atkins said not to push it, but it should run fine and idle fine.
