LANDSCRIBBLE

If i had to hazard a guess it would be between 230-250kmh on the 1km run for jay rods car. 300 is a bit ambitious for an r33 even with 400rwhp i would have thought.

Hmm ok i might give the tuner a call then , thanks.

Ok thanks ill give that a try. Do you think the ecu would throw the tune out that much for it to drop a cylinder or over fuel as much as it is?

Ok so the one thats tapped into the crossover is a 2 wire cable that plugs onto the sensor. And yep theres a hose running from the plenum into the passenger side footwell. So, if it is an IAT sensor and its connected, why would it be getting high value error?

thanks, thats what i was thinking. ive never heard of rb25's having air intake temp sensors.. the only non standard things i have is obviously the MAP sensor tapped into my cross over pipe just before the throttle body, a water temp sensor in the upper hose, and an oil temp sensor on the oil filter relocator so the ecu is fretting over a non-existant sensor for some reason?

thread revive.. and i really hope someone can help me out here, as im pretty much in the same boat as the op. bit of info about the car: 1996 r33 gtst basic rebuilt rb25, acl bearings, arp studs, metal head gasket, tomei poncams.. vipec v44 ecu (MAP sensor) atr43g3 nismo 555cc splitfire coilpacks last tuned at 340~rwhp on 15-17psi. so i know its something that i have done to it as the car ran fine until a few months ago it developed an oil leak and i had to pull the motor out to replace the rear main and front crank seals, re-tighten the headgasket and change the oil pan. turned the key for the first time today and it sounds exactly like a wrx. runs really rough, strong smell of petrol (coming from i think the engine bay aswell as the exhaust), doesnt idle steadily, and i found it difficult to notice the difference when pulling some of the coilpack plugs off. pulled the brand new plugs out. 1 2 3 4 and 6 were as sooty as a chimney, while 5 was actually wet and smelled of petrol.also all the tops of the pistons looked wet. the vipec ECU is throwing out fault code 46 - "AN temp 2 error high value" (air intake sensor exceeding 5v). apparently if this value is exceeded it puts the car into safe mode and might be contributing or causing my rb25 to act like a boxer motor. does anyone know where the IAT sensor is located? might see if i can get borrow some coil packs, and i will probably look into the coilpack loom. no obvious nicks or cuts in it from memory or do the wires just break apart from the plugs?

Cut the springs bro.

Stao does that new highflow have the variable vane thingies in the turbine housing?

Ill check that out, thanks.

I tried this, only my plug was just after the turbo outlet. Air would leak out from the rocker covers or something, would hold bugger all pressure. If there was a plug at the throttle body aswell as plugging all the hoses to the recirc valve and plenum, etc. Would the BOV still be closed shut and not leak, or because theres no pressure from the plenum being applied to the back of the recirc valve, it would be open slightly (like on idle?) and lose pressure? Im sure theres a smarter way to explain what i mean but thats all i got lol.

Dumb question, would the stock bov leak under an intake pressure test?

595rsr is an awsome tyre for the price. It does seem to wear faster but all depending on how hard you push them, like any tyre.

Sorry you have me confused for someone else. I have an ATR43G3, standard plenum, nismo 550's and ViPec ECU.

Pm sent.

I was completely oblivious until Stao rang me about it. The plugs were fine, the motor doesnt miss a beat and I havent seen any oil being burnt. Unless some of my valves or pistons are missing chunks and somehow continue to run, i was thinking maybe some slag or something has come away from within my exhaust manifold and caused this. The launch control probably doesnt do the turbine any favours either.

would this effect trap speeds much?

I will take mine to the drags after i get my turbo back from Stao and retuned. See how it likes ~6000rpm clutch dumps on MT's

if mechanics can f**k things up then why cant i?

Is that an aluminium elbow welded on there? 2.5"?

I'll post my turbo off to you on Monday Stao. Cheers.

I may be wrong but alot of track cars dont tend to use the standard brake rotors. Trackwork = Yeah a little bit. Street driving = Nah.

+1!

How good of you Stao! I might aswell do that since my motor is sitting on a tyre at the moment. Are you still at the same address?

Hey Stao do you mean even my thrust bearing g3 can be updated to BB aswell as the updated comp housing?

whats the car used for?
