Hey guys, Anyone know what needs to happen (if anything) regarding rego etc after an engine swap? I blew up original 25DET Neo, replaced it with 25DE Neo I purchased from engine importer, and bolted all my turbo stuff on resulting in a Rb25DE+T Neo. What will happen if i decide to sell the car? The engine number is now different (not to mention its a DE) Its my understanding that if you turbo a shit spec VL for example, you'll need the associated vl turbo parts such as brakes etc in order for you to be able to rego it..

Car - factory turbo auto series 2 r33 I am having some issues with boost after going full throttle. What seems to be happening is after doing 1 or 2 pulls typically in 3rd gear it will basically stop boosting the boost gauge will go up to maybe 3 or 4 so psi (running stock boost) and have the same constant exhaust note (loud drone) regardless of what gear it is in. To fix this i usually pull over turn the car off and wait 5 seconds then it returns to normal no constant exhaust note and boosts how it should. I think it might be worth noting the transmission Is pretty stuffed its the factory Auto gearbox and after warming up it will slip from 4th to 3rd with overdrive on and what sounds like 3rd slipping occasionally after heating up. I have changed the trans fluid and filter that seemed to prolong how long the gearbox took to slip. Any advice would be greatly appreciated i plan on manual swapping this car when i have the funds for a big box so if the trans is the issue it would be a relief.

Hey all, just doing a +t conversion to my 25de R34 coupe. Just hoping someone might be able to help me out with what sort of kw/psi I would be able to push through the de without sending a rod to the moon. I got a pretty stock kit off a DET with a few upgraded bits. - All factory piping, intercooler, fuel rail, intake mani and throttle body, exhaust mani, 3" dump through to xforce exhaust. - High-flowed factory turbo (20psi) - Bosch 1000cc injectors - Apexi FC with controller I know a det can push 500rwhp without upgrading internals but cause of higher comp in the DE I don't know what I should be pushing out of it. Any help would be greatly appreciated, I would still like to daily it but have a fair bit of go if I put the foot down. Thankyou all

Rb25de+t reliability if done correctly r33 s1 G'day everyone I have a doozy of a pickle. I have built a rb25de+t with good bolt on equipment front facing plenum, big front mount, standard exhaust manifold and a new standard turbo the problem is we got the car running okay with a few mods like injectors and adjustments of tps sensor so I took the car to a track day to practice drifting and it was going well until it started to misfire cylinder 6 so we found out that I either have a hole in the piston or blew the head gasket or a valve (I'll have it apart this arvo) but now I was really happy with the power it put down thinking roughly 200-250 kw and now I'm asking is it possible to beef up a rb25de (a lot cheaper than a det) and get a good tune adjust timing fuel and everything else, I like the power of high compression I'm thinking a thicker good quality head gasket and bolts but unsure how the internals will hold welcome to all comments??

OK so need some help please people just turbod my na r34 and am checking if what it's doing is OK before my tune on Thursday OK so I'll start with parts I'm running... And post problem last Rb25de neo R33 5speed gearbox conversion Was using rb25 one but think was near dead New rb25turbo hasn't arrived yet R33 turbo manifold Gtt injectors R32gtst4det fuel pump Power FC ecu stock gtt base tune atm Big front mount cooler Turbo smart bleed valve New 3"pipe decat and r32 custom dump R34na 02sensor R32gtst4det afm I wired in also tried 34 na one OK so my problem is it misses bad under boost only.. disconnect turbo runs sweet can this be my ign timing when boosting? Just want it all good and ready for my first tune as never had one what should I get done in the tune and what boost 5? And just get fuel/air and some timing pulled/retard etc...also haven't tried yet as my new turbo is on its way but the one I was using was blowing smoke and whining and no matter what it was stuck on 7-8 psi my hand controller wouldn't turn it down so waste gate? Over boost could've been the problem?

OK so turbod my r34 Rb25de neo car is half tuned as turbo blew and spent all my money on a new one haha OK so I'm not happy with the knock levels bad timing set 15btdc have set all timing in map to low but so bloody hard trying to get power without knock the load timing is hurting my brain haha most of my map I set to 18 load and rpm and upd injectors Correction from 1000 to 1400 barley any knock but just all feels crap so was wondering if anyone had a pic of there maps I can copy just for a base start for rb25+t 5-10psi and maybe injector map thanks people R33 5speed gearbox conversion R33 rebuilt turbo R33 turbo manifold Gtt injectors R32gtst4det fuel pump Power FC ecu and controller Big front mount cooler Turbo smart bleed valve New 3"pipe decat and r32 custom dump R34na 02sensor R34 na pink label afm ..
