ok i talked to jim and clark, they both told me that they dont make make an ecu program for the b.b det t25 turbo with 370 cc injectors 300z fuel pump and cobra maf.. i know some of you will think thats strange but my point is some people claim that they have this program.. they do make bb t25 370 cc and stock maf not with cobramaf. cobra maf is for 550 cc and up they told me ..? they said stock is good for 260 max and370 cc is maxed at 260 hp and the t25 wont even make it to 260 hp.. my point is i dont understand how some people on the this board says they run cobra maf with t25?

Are you sure you're not confusing the t25 with the t28?

Also, people use stand-alones and you can pretty much use whatever to program those, but generally they know what they are doing.

I see JWT's point, though...there is no use to make a program w/ using the 370s and the Cobra MAF. Waste of money, both on JWT's part and whoever is using the Cobra MAF w/ the 370s.

wtf

370cc maxes out at 260hp now? It use to be 230, then it went to 250 what nest 400hp? lol

Andreas Miko has a set up that he has been working with that uses the 370's and cobra MAF with proper fuel pressure I believe it supports around 280-300hp

 

[Andreas Miko]

Its 370cc at 58psi will give you 285hp. Bored SE-R MAF will read up to 280hp or bored Pulsar GTIR MAF will give you 300hp. There is no extra charge for the 4 bar program with this combo. I sell this comp for $570 shipped.

Doesn't it depend on how much fuel pressure you flow through the rail too? I went against the grain and used a Vortech FMU and a 255lph pump. I used an MSD boost retard box for my timing. I run 8 psi of boost and never have a problem. I still have the stock injectors and MAF. I refused to cut into my ECU harness to run the older ECU.. Even though I can't run much more than 8 psi of boost with this setup, I like it a lot. I'm going to the dyno soon. The power delivery is smooth with no surging.. I want to upgrade to a ball bearing center section soon.. I have an AiResearch T03 turbo with a .60 trim compressor wheel and I think a .63 exhaust housing...I'm not sure what the trim on the wheel is. It's been called a standard T03 turbo though..whatever that means. Why is it that no one has tried this setup before? I haven't had a problem yet. People told me it wouldn;t work.

That 58psi is fuel presure through the rail. Thats 58 psi at idle. The fuel presure at WOT is about 64 psi.I have a special JWT comp for that. As said anything will work but how well will it work. You might need to guage your findings up againt another set up. Also what is your cost on FMU and MSD retard box. If it is anywhere close to $550 you should have gone with a JWT comp. I used to run setups like yours back in 92-94 before JWT made turbo comp for our cars. Once JWT started making comp we had an average drop of .75 sec at the track quicker with the JWT setup. As for your comp,why did you say you would have to cut into your harness to change comp. All you have to do is get the wiringdiagram and pull the pins out and switch them to their new position via JWT instructions. Give it a try you will be serprised.

Just out of curiosity...how much pressure does the stock fuel pump flow on our engines? I have 2001 sentra....I don't know if this is different from the older se-r's...I never realy checked it out b/c when i got my suplemental pump, I also installed my fuel guage. So...I had no idea what my fuel pressure was. Also, are the fuel lines big enough are do they have to be replaced? It cost me about 300.00 for the FMU and Boost retard box. I wanted to get the ECU but, I would have had to get bigger injectors, MAF, old style O2 sensor....Clark at JWT told me about switching the pins. He said that about 75% of the pins from the new harness will switch to the old harness. What do you do with the others? I have the wiring diagrams for both ECUs and there are a few wires that don't match up. I have a custom Air to water I/C too. We used a starion side mount and built compartments on each ends. The I/C is layed down and has a resivoir on the side. We used a Vortech (bosch) water pump and made a heat exchanger out of half of a neon radiator with welded endtanks. It drops the intake charge from 120 degrees down to about 70 with the temp outside about 60 degrees. With Ice cubes it gets even better. I like it alot
