    VJ-11 install

    Hey, I just logged in to see what's been going on since I haven't been on here for a while and saw a BF section. You guys rock, any ways, two or 3 days ago I installed a vj-11 into my Capri, I'm only the second one to do this and the only one in the US who has it running AFAIK. Here's the write-up:

    Remove random ****:



    Notice the powersteering is out

    Downpipe bolts are usually a bitch, but my car loves me so they came out in less than 5 minutes with hand tools

    Loosen the manifold and remove the o2 sensor, I used a 3/4 inch wrench

    Pull this and remove the bracket by the disty

    Turbo/Mani is gone, make sure you remove all of the bolts in the support bracket underneath as well as all of the oil and coolant lines.

    How to attach coolant lines to avoid cutting the actuator bracket

    Assembly ready for installation

    Installed and all lines routed, I couldn't get the stock oil feed to work so I dropped $38 at a local speed shop for this set-up

    This was the bitchiest coolant line

    From another angle, the OEM oil drain works



    You will need the following parts:
    VJ-11-$105
    New oil feed-$38
    New gaskets for the manifold, turbo and o2 sensor housing-$68
    New downpipe-$100
    Many random fasteners-$20

    Reveiw: I gained 500 rpm of lag, 2250 to 2750 but gained serious amounts of power, this thing pulls like crazy; today I almost kept up with a stage 2 WRX shifting when my overboost sensor beeped (about 4500). My exahust is noticably louder because of the freer-flowing exhaust housing. I haven't been able to take it to redline yet since I couldn't get the wastegate actuator to play nicely with the VJ-11 so it has no boost control, I'm planning on rigging up an EWG.

    It took me about 25 hours with hand tools on jack stands including multiple meal breaks and parts runs and I'm no hot shot mechanic. Anyone should be able to do this swap by themselves in 2 days.

    Well Done! Are you running stock boost, or better yet, is your ECU Chipped at all to handle higher boost? If not, ide chip it, as to not lean out on higher boost, then you can unplug the boost cut, add a boost controler if you dont already have one, and away you go.

      I'm too lazy to make the wastegate actautor work so I'm running no boost control and just shifting when the boost cut beeps. I really don't like the programming on any chip out there, just are running pig rich ~9:1 and the injectors are going static for huge amounts of the rev band. I'm going to add an EWG @ 8 pounds and cruise around with that and the stock ecu until I can afford RX-7 injectors and MS. I'll add a better intake, 3" exh, FMIC and crank it to 16 psi until I get bored with it then add a t-bird hybrid and shoot for 20 and pray that my rods stay inside my block.

        if the capri motor uses the same rods as the GTX B6T then you should have no problems with them

          That's good to know. IIRC something seems to stick in my mind as breaking at 20+ psi but I can't remember what now. Any pics of how you mounted your EWG to the GTR turbo mani, I want to do something similar and have a fairly decent idea of how to go about it but would like some ideas.

            the hotside of the GTR turbo is different...the wastegate port is seperated from the turbine in such a way that a gasket will seal the two from each other. so i removed the stock flapper and ran the wastegate off that flange (well, mike built the downpipe). this wouldnt work with any other vj turbo that ive seen

              Oh, I'd assumed that you had drilled a hole in the mani and mounted it on there.

                  Ide like to compare it to the stock VJ14 at 16 psi. The 14 will have more initial boost, but the 11 will hold it out much longer, after a little lag. Eitherway, It would be fun to toy around with.

                    i dont know a huge amount about these turbo's. or any turbo's for that matter. without being retarded, whats about the max amount of power one of those could make on a BPT? assuming the engine can take it

                      RHB5's only like about 16 psi, on a b6t vj14s are reputed to max out at about 200whp and the 11 pulls an ungodly amount harder than the vj14. On damp roads I break one or both of the front tires loose coming on to full boost at part throttle with a stock intercooler and exhaust in 2nd gear. Short shifting at 10 psi or 4500 which ever came last because of no boost control I almost kept up with a stage 2 WRX and walked a 6-cyl mustang and turbo eclipse with what mgiht be a blown headgasket. My goal is 200whp repeatedly with a cat, stock manifolds, 3in exh, FMIC, MS and rx-7 injectors but I think I'm under estimating and my engine is quite tired.

                      And I have plans to race another Capri this spring, he has the stock turbo at 16 psi and a not so hot clutch while I have more than 200 lbs less weight, more tire, the 11 at 8psi and a gangsta grabby clutch.

                        The VJ14 is really a bottom end turbo. Its great at acceleration, and the first 4k rpms, then its useless. The 11 is a little bit more laggy, but has a much better powerband. Ive been thinking about the swap myself. The only thing is I dont want to do much aftermarket work, until the internals of the engine have been upgraded /rebuilt

                          I did mine with a 126xxx mile bottom end that has had very irregualr oil changes (prev owner), and a very probably going headgasket, valve seals, rod bearings and/or rings. Save enough money to fix it when it breaks, then add parts and go rape it until it breaks.

                            B6T hp limits

                            I noticed the thread stated that the B6T tops out at 200 whp. Is that the factory setup or are you stating that a properly tuned B6T. The crashed 93 323 I brough home 9 months ago had all documented dyno pulls showing 265 HP at the wheels. The thing is built tough and has a monster intercooler, rising rate fuel reg, remapped ECU, and the VJ14. The block and head where fully massaged by FlyinMiata. Whatever their site had for the B6 this thing's got. Not show boat'in here just wanting to learn where your words are coming from.
