Hey All,

I am looking at turning an 1990 R32 GTR into a tarmac rally car and have seen many evo's and wrx's running anti-lag systems. I have driven a couple of evo's with this system and it is amazing how much it reduces the turbo lag. Does anyone know if it is possible to fit an anti-lag system to a gtr (RB26DETT)? If so where would i go to do some research on prices etc??

cheers

i run a miss firing system (very similar to antilag) on my rb25 works wonders at the track, its not as aggressive as antilag. mine is an addon which you hook into the ecu.

but for a proper antilag you really need a good ecu like motec or autronics, but they are not friendly on your turbo and turbo manifolds

thanks.

so what's the miss firing system? i am assuming it works off the same basis as anti-lag. what's the addon?

basically the miss firing system miss firers per cycle, so it does not fire a coil on each cyclic. it is set on rpm so you can have the system engage between 3000-4000rpm.

real antilag will also retard the timing when it doesnt fire a coil in the cyclic

the brand of mine is GRiD its a Japaneses company, i purchases it brand new cost was $600, but it had to be sent back to japan as it had issue working with the pfc so they had to rechip the unit which cost me an extra $300. in the end i don't really think it is worth it, your better of spending the extra $900 in a good ecu which can handle antilag

I hooked my old Bee*R rev-limiter as a misfiring system. All it requires is the for the secondary limiter to be wired to a microswitch that activates when the clutch is pressed in. When this switch is triggered changing gears spark is cut but fuel keeps coming resulting in flames and no cat convertor. As I have a hi-flow turbo only it made absolutely no difference to spooling times.

      Ceramic turbine damage to engine - what did yours do?

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
