engine swap, to a turbo,

[Leigh]

gunna drop a neo6 rb25det from a r34 in

comes with Turbo, AFM, Loom, ECU, Intercooler all sensors - whole engine basicly

wondering what else i will need to do?

i currently have a series 1 r33 gts

thanks

[Leigh]

gunna put a front mount in also

[Leigh]

or has anyone done this before?

put a rb25det from a r34 into a r33?

The whole harness will need to be rewired...the ECU's are way different with the R34 being a fussy bastard with respect to having EVERY sensor working correctly.

As long as you've got the manual to work from, it should be easy enough.

[Leigh]

ill be getting it done professionally... not gunna do it myslef.. what other things will i need to change etc?

[Leigh]

will my gearbox from series 1 r33 n/a suit the r34 neo6 rb25det ?

[Eug]

I was just talking to a friend this afternoon about doing such a conversion in the future...

pending on circumstances.

the gearbox will need to be changed, wiring, loom, ecu, basically everything that made the

RB25DET run in the 34 will need to be brought over to the 33

lol ur looking at 10grand mate rofl

6 ish for an engine

then u need bigger brakes

better suspension

bigger fuel pump

as eug said a gearbox and thats around 2 - 3 grand LOL

then theres the installation and that aint cheap mate so basically the engine , gear box, good brakes good suspension and fuel pump will set u back 10grand already if u get suspension , fuel pump and brakes 2nd hand then u'll still be looking at 9grand or so, and then installation of the engine and the complicated wiring the r34 contains will set u back a shit load more.

[Leigh]

got the engine and that comes with Turbo, AFM, Loom, ECU, Intercooler all sensors

ah so i will have to change gearbox?

breaks n fuel pump i know..

suspension already got good one in.

just put a rb25det into my 32 however it wasnt a neo. pretty straight forward although i didnt personally do it. tailshaft needs to be fabricated as does the gearbox mount. needed to get a new pinnion assembly for speedo going from mech to electrical however not sure if u will encounter this problem being a later model car to start with. i know in queensland regulation states u must have brakes at least the equivalent from whateva car the engine is from, personally i went for s15 as being 4 stud they didnt have to get redrilled or anything and are actually even better then the standard 33 objects i think. (dont quote me on it). depending on diff to my require different diff

cheers, matt

gearbox may hold up if ur gentle. but then again whats the point in havin a turbo car huh??? i looked into this b4 and this is a VERY messy job hey. If its what u wanna do, then go ahead, just make sure u got a fair amount of money in the kitty otherwise ur ride will spend a shitload of time in the shed.

[666DAN]

Realistically...the extra cost of putting the NEO in an R33 isn't really worth it..just put in an RB25DET from an R33 and you'll save thousands which could go towards a bigger turbo etc etc which will put you way ahead in power stakes than the mroe expensive NEO

[Eug]

i have read somewhere that the neo6 has a few extra goodies like stronger internals??? (dont quote me on that) which means you can probably run more boost) it makes more power stock like 200ish kw? and has a far greater potential than the standard RB25DET

[NA_R33]

your fuel pump wont need to be changed, my stocko is running my V8 with nitrous, there a pretty good standard pump, You will need to do the gearbox as yours will probably not handle the power as well as the diff, depending on how u drive, i broke 3 diffs with the rb25de though so maybe im a little harsh on the car. theres not much else u need, brakes can be an afterthought and dont need to be done straight away nor does the suspension. Ive had the V8 in my gts with stock suspension for almost a year now, its a little soft but u can make do with it.

About the brakes, it depends on what rules u use, there are a number of sets of rules regarding engine conversions, All i had to do is make sure my car had 4 wheel disc brakes.... Mine definately arent up to the task but rules said it was fine.

Depending on where ur from u will more than likely have to get it engineered.

[666DAN]

I don't know about the pump...my one didn't have the balls to keep up with the boost...maybe the R34 one is dodge?

[Leigh]

ah, well the r34 engine im getting cheap no where near 6k. so thats why im looking at doing it...

fuel pump ill replace anyway...

already got aftermarket suspension...

breaks yeah i know, but i wanna keep same stud pattern as i have 18" chromes..

[paully_tee]

u wanna kno wat ur better option would be?? go an RB25NEO NON TURBO and then turbo charge that existin motor. Just dont run rediculous boost. I looked at this option and it didnt seem that hard.

[666DAN]

RB25NEO NON TURBO and then turbo charge that existin motor

That's just a stupid idea!!!! It'd look like this piece of crap and probably pull just as hard on low boost

[paully_tee]

hahhaa. im not to sure wether ur pullin the piss.... so i'll just clarify it. lol. RB25NEO is almost a direct swap into a r33. Onli difference is coilpacks from memory. U can grab the ECU from the r34, not sure if is reprogramable, otherwise just go aftermarket. Then just bolt on turbo, manifold, intercooler, etc. I rekon u could get away with this option for abt 5k.
