Turbos And Choosing The Right Computer Need Help

[335]

Hello

I have a R32 GTS-T with a twin front pipe, cat, cat back and cannon muffler. I have a fmic and a pod. I also have a RB25 turbo that I have not put on yet.

My goal is to reach between 350 and 400 hp. I know that the RB25 turbo cannot reach that.

I have a chance to buy a used E-Manage unit with the loom or $200.00 but no cd or a flashed R32 GTS-T computer for $100.00.

The E-Manage is set to 1.1 boost(this is the only info the store has for it) and the flashed stock computer is set for pod, front pipe, catback exhaust, has the boost cut deativated and has the speedo cut deactivated.

Which one is a better buy? The stock flashed computer that is just plug and go or the E-Manage? I do not know when I can have the E-Manage tuned.

I have to choose by today Japan time.

Also if I put on the RB25 turbo, will the computers probably work fine? Also I have yet to buy a boost controller.

Best to buy a tuneable ecu. U need to tune ur ecu to suit ur particular car, especially when ur going for 350hp.

Few options but cheapest is normally a NIStune ecu.

U should save up for a bigger turbo, injectors, air flow meter and ecu.

For now just install the rb25 with the stock ecu, and get an upgraded fuel pump such as a walbro Gss342, and run with the stock ecu on sensible boost 12psi

I wouldn't buy any of that junk that you "need an answer by today"

Nistune is clearly the best and cheapest option for you.

Stock flashed computer is not plug and go. It would be plug and stick it on the dyno to see if it is anywhere near your current set up's requirements and then it is not tunable so has very limited use. E-manage is no use if you can't tune it. Since neither is any good to you forget about the deadline and set about getting a Nistune chipped ecu or pfc etc.

350 is my main goal down the line, for now I just want to get a higher whp than stock and try it with tuning. So even though the flashed cpu has the mods I have, it probably has differences that were tuned for the other car? I could run into problems with it?

Would it be worth it to put in a GTR pump? My friend has one he can give me.

Where can I get a Nistune? I live in Japan, I can try to ask around but is it something you have to have your computer flashed on a Dyno to do?

I have to decide today because the store will only hold the parts for one day, its a popular used after market parts store. How do I get a Nistune?

I might be able to have the E-Manage tuned by the summer, I just have to find a affordable tuner. If it is only around 500 dollars I can do it soon.

I cannot find any PFC for my RB20 here. I have access to a PFC for a RB25.

So the flashed computer is out if I was to choose one?

Forget deciding today.

Go and do some decent research before making a decision.

Too many decide "right now" and then end up wasting their money - which is the path you are on right now.

Sounds like ur trying to do it too quick and too cheap. Shop around for a 2nd hand power fc seeing ur in japan. U should be able to find one for under $1000. Take ur time and do ur research. Do it once, do it right.

PFC is probably the way to go, Nistune is a good cheaper option but there wouldn't be any tuners in Japan comfortable with it (let alone the english only interface).

He'd probably have an easier time finding someone who can still program EPROMs using ROMedit (with it's annoying Japlish interface), seeing as that is where it was born and used for 10+ years.

My vote is also for a used PowerFC. But if it was me, I'd get a Nistune setup and tune it myself. Well, that's what I did, so that's what I would.
