maybe someone can correct me if Im wrong but, I think a bnr33 fuel pump should be able to deliver the power... Simpler to have one pump instead of two.

I would do more research on your wideband selection too.

Intercooler
clutch
check all bushings etc..

sorry yeah ive had an intercooler laying around for a while too so i forgot to mention that. clutch is purchased; had to do a auto to manual swap. what do you mean do more research on my wideband? as far as bnr went i was reading reviews on them and it seemed that some people had problems with them and i knew that people run dual bosches all the time and dont seem to have many issues out of them but hell, im up for suggestions and what not.

well what I meant is try to use what the majority of other people use on the forum, in case you need help trouble shooting any issue that might occur. But If it work then it works.

dual Bosch 044 fuel pumps seems completely unnecessary for a GT35. Lots of people are running single Denso pumps (Cosmo, Supra) or just a Walbro 255. I don't see you maxing out a good quality, properly wired single pump with that turbo. Go with the single pump, it will save you money and complexity.

Agreed, I would go with just a single Walbro, it'll save you tons of money. Worst case scenario if it's running out of flow (which it won't) you can use a voltage booster on it (Kenne Bell, MSD, etc.)

The T04Z can net you up to 550ish whp, so a single Walbro will be pushing it if you run it full out. I know a member J-Rat was able to hit 550 or so whp with a single Walbro, but he dropped the base pressure so that it could flow enough. Are your power goals the same?

sorry for late replies. goodfella from what I heard it was the fuel pump, I dont know what is true. but I heard they had some problems. As for what kind of power I want about 450 whp but I want to be about to turn up the boost and be able to throw down more thats why I changed my mind on my turbo and now am going with the to4z. I already posses two bosche 044 fuel pumps so I believe I am just going to run dual in tank pumps unless you guys convince me otherwise.
