cool, that's what I thought, what pump did you go with? I am looking at a walbro 255lph as it seems to be the "smallest" I can find and figure that's probably close to stock. appears to be a in tank replacement. https://www.ebay.com/itm/255lph-500HP-Uprated-Genuine-Walbro-Fuel-Pump-For-R34-GTT-Skyline-RB25DET-Neo-/111883558315

I am going to guess and say that the wiring, fuel rail, injectors etc. all don't "need" to be replaced when replacing the pump to allow function of the pump to work properly rather needed if looking to gain possibility of "more power" when changing out other items. and does any one know the stock LPH fuel pump rating on a R34 RB25DE and a R34 RB25DET?

not looking at changing everything just a proper fuel pump for a GTT DET engine with all stock internals, turbo etc.

no other parts need to be changed at the time the fuel pump is upgraded?

I'm sure that has solid engagement, but how's the pedal feel? do you have a lightened flywheel as well?

tank sending unit all reusable from the rb25de stock setup or will tank, sending unit or anything else need to be changed? I am looking at the 255lph 500HP Upgraded Genuine Walbro Fuel Pump For R34 GTT Skyline RB25DET Neo thoughts?

ok, now we are getting some good tech info, so the fuel pump , different from a rb25de and rb25det version? what are the stock fuel pump differences/numbers? so what's the recommended pump to put in with the rb25det?.... I see Walbro 255lph pump listed a lot, is that a widely used unit?

no matter which trans and therefore push or pull style I end up going with, what is anyone's experience with the brand SPEC for clutches? or one they can recommend for essential a "stage 1 clutch", looking for stock or a little better, do want to keep the pedal feel as soft and easy /close to stock feel.

I will be trying to find a stock shifter setup for my new FS5R30A 5 speed gear box (GTT RB25DET) other wise I may have to go aftermarket, if I cant find a stock one, I do find the brand "Cube" shifter for a R34 RB25det , any one have any comments regarding that shifter? or recommend a different shifter setup?

or running lights? ultimately, what turns it on and off?

on a R34 rear bumper the red light on the right, is this light to be on with headlights only? or is it on a separate switch?

all the places I have contacted said they ones they have do not fit R34's which is why I posted here, thought someone would know.

I never mentioned Cusco brand....its not just 20 dollars its around 150 for me as I am in the US, no one has them and I have to order from another country. so no ones knows if the thread and or diameter on a s15 E brake would be the same as a R34?

any reason I should get a GTT rear diff and put in a aftermarket LSD instead, of putting a aftermarket LSD into my GT rear diff?

can any one define what parts and what makes it actually "stronger" or is it just simply less prone to break when abused?

if they list it to fit a S14 and S15 would it fit a R34?

ok, so best to not try to "make" mine work. I will plan to get this then: https://www.ebay.com/itm/CUBE-Speed-Premium-short-shifter-for-Skyline-R32-R33-R34-5-speed/223279617684?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D225073%26meid%3Deaba7acfdd5e45e3bb22a4e1af95dc1e%26pid%3D100167%26rk%3D6%26rkt%3D15%26mehot%3Dpp%26sd%3D221840569882%26itm%3D223279617684%26pmt%3D0%26noa%3D1%26pg%3D5411&_trksid=p5411.c100167.m2940 question: would this give me everything needed, to replace entire shifter assembly or would I have to use some parts from my current shifter assembly to mount and make work?

yes, drive shaft, trans mount, etc. any other things not previously mentioned? I found a brand new neo GTT RB25DET 5 speed trans but it doesn't come with anything...(wiring, shifter ,etc.) will these items taken off of my current FS5W71C trans fit onto a FS5R30A ?

trying to find a E Brake Handle Brake Drift Spin Turn Knob Lock Button that will fit a 1998 er34 skyline 25gt find many listed but none list a r34 as compatible. thanks

I will be replacing the trans with the "big box" 5 speed from a GTT. anything else?

so what are the differences in the transmission and rear diff?

so what are the differences between a RB25DE neo 5 speed and a RB25DET neo 5 speed?

I have a 1998 ER34 25GT 5 speed 2 door skyline. I have swapped engine for a R34 GTT RB25DET, along with GTT brakes and suspension, and triple dash gauge. plus other things like seats, steering wheel, shifter and a bunch of other items that are no mechanical related. my question for the SAUskyline community is what else is different between the 25GT and 25GTT R34 models I know about turbo engine, HICAS ,Traction control, LSD rear diff, and the other things I already changed like brakes etc. but what else is different? thanks please intelligent replies only

like this one ? https://www.ebay.com/itm/132344218322?ViewItem=&item=132344218322

or is this something to be considered with and best to swap entire trans at same time with a GTT trans?
