Hey guys,

I recently joined this forum because in the states there are a few good places to get information but I found a lot of people that recommended coming on here. For the last few days I have been digging through a lot of posts on here and have come up with a basic notion but I would like to here from the guys that actually have r34 rb25det with a tiptronic transmission. I got extremely lucky and found a r34 neo rb25det front clip here in the state for a really good price and I am considering getting it but the fact that it is a tiptronic turns me off a little bit. What I wanted to know is just the overall ratings you guys would give this system. I have a room mate that has a rsx with tiptronic and it doesnt seem all that bad, but what worries me is the strength of it. I read that one guy was running about 250kw through his but it eventually blew. I would probably try to get mine up to running around 10psi on the stock turbo just because i dont want to stress out the transmission all that much. Also I was wondering if any more of you guys got that shift kit from the group buy and if that has been proven to strengthen the tiptronic at all. Last but not least I'd just like to know your honest opinions on this motor and tranny, hopefully the guys that have manual transmissions dont come in here and go crazy :P but any information you guys could give me woudl be a great asset. Thanks

woops and I wanted to know for those that have raised the level of boost what type of engine management are you using? I have read that a lot of the products out do not get along with the tiptronic all that much

all 4 wheel sensors? what's this fellow on about?

you might need wheel speed sensors for the traction control butterfly if you want to use it, but you can easily replace the whole throttle body on the neo for something else that doesn't use it - our just don't connect it..

i forgot to state that this will be going into a s13. now what i was wondering is if i could get away with sourcing a rb20/25 tranny bolting that to the motor and using the manual parts that are in my s13 shell to complete the transmission swap or am i just a retard and only scratching the surface? because the s13 shell has everything related to the transmission in it

If you are going manual... You should be able to get by with using the S13 pedals, R34 clutch master cylinder (required for a heavier clutch), the s13 lines and things -in fact you wouldn't be most of the neo parts ones anyhow as they are for the R34 shell.

Where you will have to adapt probably is use the slave cylinder line and slave clyinder from the rb25 gearbox, and also the cross member you may need up to suit S13. And a tailshaft made up as well (would need that for the auto anyhow would say)

You will probably have a few issues of working out which parts of the neo is wiring for the auto transmission, but most often its the auto has the extra crap for wiring, controllers, etc that in a manual is not required at all.

In the tiptronic there is probably more interface between the auto ecu and engine ecu (guessing here), so its possible without the auto controller hooked up in may go into spastic mode... In that case you might have to source a manual R34 ECU.

so i would need the r34 master cylinder and couldnt get away with using one from say an r33? the guy selling me the clip has the full original wiring diagram and extras taht he imported with the neo clip

edit: also if need be i can pick up a power fc to do away with the ecu

Have you done a swap and have experience with this? What are you supposed to swap the TB with?? What if his front clip doesn't even include the AT computer?

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
