    I would use the JDM intake but stock turbo and cams first, and get used to that and then swap out to 2554r, then the cams last. Get lap times at the same track with all these setups.
    Before putting the cams in you'll want a better Damper. The factory one doesn't help past 6800rpm and you'll beat your bearings to death. Also, stay away from light flywheels. You'll get more top end from a good head deshroud too. Follow the SCCA spec Miata instructions for that.
    Another tip; if you're using that Miata PNP, adapt that JDM plenum to run a Miata throttle body. The b6t one is smaller and I think it'll be a restriction over 7500rpm. This is just theory, as I haven't had a chance to test the difference side by side.

      I have the stock exhaust manifold still. I put a .5" adapter plate on it then the turbo on that. I had to grind the pad on the turbo down some to make it fit. Its tight. The actuator is touching the block. If i keep the t25 t28 i need to have a better manifold made to make it fit right.


      so Advancedynamix how about that gt2554?
      1990 (LUCIFER 2.0) fully built BP+T with E153, Fueltech FT500, traction control with hopes of 600hp (i drank to much of the KOOL-AID)

          • The Porsche is my comfortable, chill car. I laugh when people consider it to be a performance car. I've got KW V3 coilovers on it with custom rates and valving for me and R compound rubber and it still won't hold a line like Pedro, never mind hold like Tweak.

              I'd have to get 900 for the turbo. It was used lightly for 4 30 minute sessions on a properly tuned 1.6 that was running race fuel. So it's essentially brand new. It's the aftermarket Garrett 2554R, not the Nissan sr20det turbo.

              • I also have a Nissan gt2554 around here somewhere. It's the plain bearing version from the sr20det. I'd let it go for 400 bucks.

                • If you want a cheaper upgrade that wouldn't require the external wastegate, use a Garrett GT1752 from a Saab 9-3. It's got a really nice internal wastegate. It's a similar size to the VJ11 but flows more. I bet it would spool like a a VJ14 but be good for 220hp. They are common and cheap at salvage yards or on eBay. You'd need to drill the mounting flange. It's a t2 flange pattern, but has studs rather than holes.

                  • The top left is a VJ11, Right is 1752. Below the vj11 is the 2554R. Below the 2554R is a 2560r.

                    • And, while we are talking B6t turbo options. Here is a gt28r inside a corksport vj14 housing. Direct bolt on gt28r. I had this ready to go on Tweak, but never felt I needed it.

                        where did you find that housing! thats crazy. I dont think that would be a good idea either. I'm willing to be there would be boost control issues with that internally gated setup, and that exhaust housing for that compressor.

                        • Charlie, why does that manifold look different than all the b6t turbo manifolds I have?
                          Trees aren't kind to me...

                          currently: 2 88Ls (Scrappy and Jersey), 88LX, 90L(Pepe), 91L, 91GL (Skippy) 93 GL Sport (the Mighty Favakk), 94 (Bruce) & 95 Aspire SEs, 97 Aspire (The Joker),
                          94 Justy 4WD, 87 Fiero GT, plus 2 parts cars. That's my fleet.

                            I agree. The housing was bored out quite a bit to fit the gt28 wheel and the Garrett turbine is much higher flow than the IHI. Corksport made a dozen or so hybrid turbos and they used an early version of what would become the gt28 turbo. This one had a .70 compressor when I got it, but I installed this brand new .60 28R. This is a smaller compressor than what Corksport intended.
                            I bought this unit ,with a broken turbo, from Matt Shayka and had the turbine ceramic coated and installed the fresh Gt28r. I've since sold it.

                            Not sure why. I bought it brand new from Mazda Motorsport. It's now living on Tweak.

                            • Hell i dont know what i wanna do/should do on lucifer. The vj14 is just not enough for me. So i need a bit more but want it be able to still use it.

                              • That's the thing I don't understand. You say the vj14 isn't enough, but you've never had a good running b6t, and you've never taken the time to get used to the car. That's like saying a GT3 Porsche isn't fast enough for you, when you haven't driven one on a race track. Lol.
                                The b6t runs like absolute dog crap unless it's set up like it should be. Your car was not set up properly at all when you got it and you judged the stock turbo by the way that hacked up setup ran. The engine management system NEEDS to work within it's parameters in order for the engine to perform correctly. These systems adapt pretty well to some modifactions, but won't adapt to others. You absolutely can not have air leaks or openly vented diverter/blow off valves, you have to have a certain amount of exhaust back pressure and you must have good grounds and properly adjusted ignition timing. These things are critical, otherwise the car will be slower than a good running b3 (though it'll feel faster, you'll see on a race track that it's not.)
                                Before deciding a stock b6t isn't enough, why don't you drive one? It won't feel fast, but that's deceiving. Real performance is not intimidating, it's refined.
                                Example: Hop on a big inch hard tail custom chopper and take it for a hot lap on your favorite road. Those things "FEEL" insanely fast. Now throw a leg over your superbike and cruise the same loop. It won't feel as crazy fast, but it'll be much much faster than the chopper. This is the difference between poor engineering and refinement. The superbike is a balanced package. They are deceivingly fast. It's hard to take the speedometers seriously because triple digit speeds are a breath away at any time.
                                The b6t swapped festiva is a supercar. It feels refined and planted even under extreme conditions. It's deceivingly fast.
                                If you try to get bigger HP numbers from a b6t by just putting a bigger turbo on, you'll upset the balance. You will loose that seamless and tractable mid range. The manifolds won't support much top end gain, so you'll sacrifice your mid range for nothing. You'll only make the car slower. It may feel faster though, because the TQ curve now has a spike. TQ spikes fool the driver into feeling like the car is faster and more powerful. TQ spikes spin the tires and create TQ steer issues. These TQ inconsistencies are not fast though, and they make it hard to drive fast. Spinning the tires and TQ steer is not fast, it's distracting. The tuning industry has thrived on bad ideas for a long time. The typical car guy doesn't know what fast feels like and it feels like the car is faster when it's hard to control. That's why poor tuning sells so well. The problem is that this mindset will cause people to misjudge a balanced and refined setup because it's not out of control.
                                On the race track, the truth comes out. Proper engineering shines and poorly tuned cars turn to lap traffic. A b6t Festiva can turn a Ferrari F430 Scuderia into lap traffic, yet it's not fast enough for you. Hmmm
