  1. FS: RB25DE with ITBs and MS3

    It's still available and I haven't made another video. I have the car down right now, I am test fitting an R200 short nose diff for a drive shaft. I will have it put back together by next weekend. And can shoot a video.
  2. High fuel pressure after fuel pump swap..

    I just put on the original return nipple on the tank with some creative reducers.
  3. High fuel pressure after fuel pump swap..

    This shows where I put the FPR, directly above where I cut the vent line.
  4. High fuel pressure after fuel pump swap..

    The vent line does go back behind the head and joins in with the rest of the fuel lines. I cut it off near where they all join up and connected it to a rubber hose. I installed the regulator directly above it in the firewall. Looked clean. The hard line joins in with a hose in the back that goes to the top of the vapor tank. If you don't rearrange it, it will still work. It will just sound like someone pissing in your gas tank. I put the return line in one of the vent lines in the top of the fuel tank right above the original lines. I then ran the line that came off that tank vent to the original return with some size reducing. Kinda switching the two hoses. Not really sure why your vacuum changes. Maybe when the fuel pressure equalizes, the engine runs the way it should, changing the idle load.

    I will make a better video by the end of the weekend.

    What type of video would you like to see?
  7. High fuel pressure after fuel pump swap..

    Check your return line. I am not sure on your car, but my 240z had a tiny return line. I used the vent line that usually runs down the driver's frame rail as many do on the 240z for fuel injection. I have never had any issue with the stock RB fuel pressure regulator on the walboro pump. This is my third car running that combo. Pull the rubber return hose off the hard line and put it into a gas can and see if the problem persists.

    It hasn't been dyno'd. I have seen seen 55% duty cycle on 444cc injectors close to the top end. The ignition map isn't optimized yet, so the fuel consumption isn't too accurate for HP calculation. I would say 200whp wouldn't be too far off.

    Because photobucket is lame: How the engine looks in the car. The modified header. Stock R32 mounts vs custom mounts to correct the engine placement.
  10. Problems tuning my RB25?

    Stock RB25 maps do something called richen/retard at higher boost. This keeps people from just turning up the boost to get more power.

    I used to live in San Diego, would have been convenient.

    I am wanting to go back to a turbo motor and want to sell my current setup. It is running in the car right now, so when someone wants it, I will pull it and ship it. I have shipped freight before, so it won't be an issue. The details: 08U short block (RB25DE from an R32 GTS25, no VTC) RB26 Head RB26 ITB w/ custom velocity stacks A reworked Kobe exhaust manifold originally for an R33 RB25DE Megasquirt Version 3 FS5W71C transmission (from an R33 GTS25) w/ modified shifter to accept a Datsun knob Custom oil pan Custom engine mounts made from the design of the R32 mounts, (shifter is in stock position) There are three options for buying in this order. I wont split up the set other than what is stated. The last option is a total solution, about as "drop in" as you can get. The Wiring will be about 95% due to the option you want to go with on fuses and relays to get the ECU to run in the 240z. All the wires will be labeled to allow for easy wiring. This is a running, driving setup. The compression is about 195psi across all cylinders. The motor was put together about 3000 miles ago and has had two oil changes. Engine only $2000 Includes: The full assembled engine Intake w/ velocity stacks RB26 444cc injectors w/ resistor Exhaust Manifold Wiring harness for MS3 Either the custom mounts or factory R32 RB mounts. Rear sump oil pan Alternator No other accessories (P/S, A/C) Engine and transmission $2500 Includes everything from the engine plus: Transmission with custom cross member drive shaft for the later 240z (same as the 260z, 280z) made for the custom mounts, R32 mounts use factory 240z driveshaft Shift lever modified with a Datsun lever to accept the smaller knobs (knob not included) Engine, transmission, and ECU $3000 Everything above plus: MS3 with MS3X ECU. There might be more HP after a good tune, but this tune runs well.
  14. Wanted: R200 moustache bar for S30

    Looking for a R200 moustache bar for my 240z. Please reply here or PM me. Thank you.
  15. I am about to start my rear drive train upgrade by installing a short nose R200 using the Techno Toy Tuning R200 swap. I want to retain my BC Coilovers, but I dont want to cut off the tubes from the rear suspension unless I have to. Does anyone know if BC will just sell the tubes? Or if there is anyone here that is about to do the swap that wants to trade the tubes for my already welded tubes plus the axle housings?
