Need gearbox asap, even if it needs bearings or some work.

A good mate of mine put a stock Rb30 into his C210 coupe, bolted on a set of extractors, Pod, CAI, advanced timing ETC and ran consistent 15.0 sec. passes at our last R31 Drag day. In search of more power, he made a kit to mount the Toyota Sc14 (I think?) supercharger, bolted it all on, only running 6psi he managed a 13.5 quater mile. This all on an unworked Rb30. I would estimate that hes running close to 150rwkw now.

WTB: Rb20 oil and water turbo lines.

Anyone got a set? Cheers- juddo

Hi all, am about to install the turbo on my 25DE, where are the blanks on the side of the block in the Rb25's?? I know the rb30's have oil in and out and a water return blank that unscrews for you to bolt the lines onto, but is this the same for the RB25's? cheers- Juddie

Thought of selling the car, but it there is way to much sentimental value in it to do that, I dont want someone else's hard work in another car, just wanna do it myself. Fair enough it still wont be that fast with the turbo up and running, but im not building it to produce 200rwkw either, to tell the truth i'd be happy with 140rwkw. Thanks for all the advice guys, im gonna do it in the next fortnight, and will let you know how it all goes.

Cheers Pauly, your a champ

Heres the damage so far: Working turbo perfect size for my application, low k's, with dump and front pipes and all lines- $150 25DET injectors and stock SMIC-$25 All pipework- Still yet to aquire-Only after stock 20det pipework Exhaust work will be one by a mate very cheaply, also spoke to a local high performance shop, who said that I can use the 25det ECU to cure most problems???? Is the true? Manifold- $20 Various gaskets--cheap as the old man's a mechanic Also spoke to a friend, who said that the head gasket should be fine on 7-8 psi, anything more and then I'd be looking at the 1.9mm Job.

Well, Like i have said, the engines in an R31 skyline, I bought it this way. The power delivery below 3.5k is awful, basically im just after something to plug the power gap. I only want to run about 7psi, which is why Im not after a huge turbo and im not after huge power figures. I dont intend to drift it (well not competitively anyway), I dont intend to race it on the strip, I just want to have something thats a bit more user friendly on the road, I hate having to thrash the guts out of it to get it moving, once its above 3.5k its a great engine, pulls heaps better than an Rb30, and its very smooth. All I am after is a few opinions from you guys as most of you know your shit when it comes to turbo engines, I'm a turbo neewbie and dont have a huge budget, I will have to money for the turbo next week, but I dont want to buy it if its going to be a waste of time, or I need to do a lot more internal work. I have spoken to a shitload of mechanics that said they cant see why its not possible, apart from the whole ecu drama and getting it to a decent tune on the stock ecu. I intend to have a decent size intercooler even tho I will be running low boost. Cheers guys- Justin

Been a member for nearly 2 years

If I need to lower the comp ratio, why did the guy on here run his R34 with the same conversion for nearly 3 years, with not 1 problem???? I have heard shitloads of people have done the same and not had a problem, unless you know someone who has actually done this?? Cheers for the info, but im getting mixed stories, The ecu bit I still cant understand.

Hi all, I have most parts to do the conversion. I plan to use the stock ecu, is this possible and if so, what problems am I likely to encounter along the way with fuel etc????? Ideally im after someone who has done this and had the odd drama to explain how they went about their conversion. The 25DE is currently in an R31, also am I going to need to upgrade fuel system etc?? Cheers guys, might sound like a newbie question but I need to know so I can start planning the install finally.

Running stock 25 ecu, Turbo came off a car that had a genuine 60k on the clock, has slight (very slight) shaft play, seals are apparently fine, made 154rwkw on 11 psi on an old skool 300zx. Has been checked over by my mate who is very fussy. Comes with all lines, dump and front pipes for $150??? Reasonable? Does anyone know if i can run the stock 25DE ecu with the turbo setup?

Cheers mate, I was told that the VG20 turbo was in between a silvertop 20 turbo and R33 turbo in size, this being the reason I was interested, it also comes with dump and lines for $150, what do you think?

Finally got the funds to do the turbo conversion, basically what im after is a turbo for a low boost application, either silvertop 20 turbo, or maybe an R33 turbo if the funds stretch that far, anyone know of one floating about let me know. I am actually looking at a turbo off a VG20DET that a mate has, does anything know much about these turbos, apparently they are stamped the same as a redtop rb20 turbo, but have different internals, any truth to this? Cheers- Juddo

will let you know about turbo asap, very interested

what about stock coler and pipework?

how much r u asking for the series 2 turbo?

im in tassie guys

As title says, need stock R33 turbo, front and dump pipes with oil and water lines

f**king Goobers

LOL A guy I know tried to tell me his bro's fully sik VL was running 25psi on stock internals along with a 75hp NOS shot when he was racing, LOL. An dhtats everyday, what a wangoff

Thats a shit dyno, a 25de should pull a lot more than that, go elsewhere mate, both dynos u have been on are shit

Veedka, dont let the turbo boys give you shit for owning a non turbo, at least u wont have the fuel bill they have, good choice mate, looks like a nice tidy car, for those of you that said he couldn't find a decent car for his budget, eat shit. I have a 25DE in my R31, f**kin great engine

7-8 psi max for me, I want it to last
