hey guys

im having a few dramas with my 180, with the wiring, so im thinking about ripping out the motor and putting in a 4.0l lexus quad cam v8 and run a twin turbo set up on it

i was going to rip out my rb25det and do a custom install on the v8, get a bellhousing adapptor and run a supra 5 speed adn then run a twin t70 setup and run 2 38mm wastegates, do fuel setup, fmic and exhaust

what do u guys think, im looking for the 8 as i think it will have more torque and have the potential to make more power

so tiny wiring problems which can be fixed by a new loom ($500-$800) is making you go to a non nissan V8 conversion?

good son of rajab. Hope you have a good 15k sitting around as its not going to be cheap. Torque of a v8 is hardly what a 180 is designed for, let alont a TT one...

god i love peoples enthusiasm for conversions, zoom magazine is a contributing factor, and makes everyone thinks 8 secs is only a stock v8 and a set of twin turbos away, trust me theres plenty more than that, and 99% of the conversions like that done in magazines etc are done by mechanics/fabricators/or people in the trade.

labour and parts would be a killer, and its not bolt in lets race, its make this, fabricate that, etc etc, wiring issues.

id say a lexus v8 with stock internals and compression wouldn't last all that long with a set of t70 turbos and running 8's, so plan for a rebuild in the near future too, then its more bucks $$$ :O

but if you install this motor... will you still have the same wiring problem?

also with that much power and tourqe... are you even gonna be able to drive it? eg 1/4 times will be hard, too much wheel spin.. but to fix it youll have mass tyres... unless you gonna have it not overly massive power... which wouldnt be worth it if you can get the same power from your rb25det...

yea?

not to be rude or nothing...but ill say it straight rather then beating around like everyone else. it sounds like a wank and i am a trady, with a family full of mechs and engineers and i probably wouldnt bother with such a large hassle..even minus the labour it would be expensive and time consuming. Just thinking about it, almost everything involved would be custom, even moreso if its a toyota motor. you might have half a chance with the infiniti v8.

engine mounts, gearbox mounts, tailshafts, diff, manifolds and exhausts (will it all fit, high mounts or some superwide mounted turbo setup to suit a t70 as they arent exactly a small turbo. engine is already super wide from V config of engine) I was gonna suggest running turbos up front, as ive seen that in some drag and race cars...but you would need a clutch fan, and a big ass radiator to cool the thing as a twin turbod v8 would run rather hot.

thats just the start of the list off the top of my head in the last min. But it sounds like a great idea mate....Just a side note..How much for the rb25 and gearbox mate? I need em for my race car.

Cheerio.

Twin T70 setup? you have to be f**king kidding right.

I seriously hope you wouldnt commit to spending that much on TT V8 conversion only to run two cheap and terrible eBay special turbos on it.

:)

well then....

there is already a 180 with this set up on it... fairly decent fit.. as for the suggestion of the vh45, that is an even bugger motor,, i have seen it done on a s13 and it sticks out the bonnet... and yes i khnow theres more that 2 turbo's to a 9 second car and i know all the headaches cause ive done conversions before

    • If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.
    • Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.
    • Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice  
    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
