Rb25det highly modified

[Benrobinson]

Hi all, wondering if anyone can help. I am looking at buying a skyline. I’m a newbie to skylines completely. It’s highly modified running 600bhp. Spec is brilliant can post if need be. My main question is. How many miles will it last? I won’t be thrashing it. I’ll be servicing regularly. Will I do a 100k miles? What will need replacing ? What can go majorly wrong? Sorry for all the questions. Cheers guys.

It will break and cost heaps of money.

 

 

 

Dont buy it if you are after reliable miles mate.

Well, the good news is that 600hp is more like mildly modified these days, so if it has been done properly it should last a while.

Details of what has been changed (and what hasn't, and how many klm) might help provide specific guidance

[Ben C34]

Actually if you arent going to thrash it why buy it?

That is the spec. @Ben C34 is that  serious reply , because that is what I’m worried about I want to enjoy it. I don’t want it to be in the garage every 5 mins. I will obviously drive it properly but Am not going to be hitting the limter every time I drive it 

[Dose Pipe Sutututu]

Should just buy mine, proven to be reliable.

Lasted 2x 10min sessions at Eastern Creek GP Circuit and didn't create new crank case vents.

I would say it's a serious reply. 

Assuming the car is built well, how long till you experience breakages is 100% down to how the car is driven.

If you use it on the street and drive around like a cop is following you, the car will last a looooong time. 

If you are driving it in anger or using it on the track.... you might break something on your first event. 

Consider this, proper track cars at that power level (850HP), that are raced over the year, might do what 8 events in total? If nothing broke, they would still have the engine pulled down and inspected each year. 

So yeah, 850HP from a 2.5L engine, the engine is a consumable item. If you use it, you consume it. It's up to you how long it lasts. And also, if the car is driven hard, expect to be regularly replacing that gearbox and the driveshafts if they are stock.

Whats this about? You selling it or just bought it?

Looks like it has a lot of good parts but that doesn't mean shit if the builder was a monkey. How do you know its been built well?

Buying a modified (mild or more) car will always be fraught with danger, you have no idea the competency of the mechanic (or maybe you do?).

600hp is a lot for the street, if it is to be a street car and driven as such then you're more likely to be fine over the long run.

I'd say he copy pasted the whole advert without trimming off the confusing shit.

[Ben C34]

I'm also assuming this is heaps of cash. If you arent planning to actually thrash it, seriously why buy it?

 

It's hard to not worry about stuff breaking with modified cars. Stuff breaks. If you don't want stuff to break you leave them alone.

But Spec 2 build bro $$$

[Ben C34]

I'm getting uk vibes woth the BHP talk and miles.

They do the made up engine Hp values don't they?

[Murray_Calavera]

Only ever seen BHP used in the UK. 

[robbo_rb180]

Yeah seems to be UK after a quick google.

Anything that modified will require some form of constant maintenance.
Pretty good parts but are you going to use the car to its potential?
 

[joshuaho96]

As with anything there is no replacement for going and actually seeing what the car actually is instead of what some seller dreamed up. Lots of UK cars that are supposedly immaculate but all the attention is on the exterior paint and nothing for the underbody. These cars are crazy expensive to fix between Nissan doubling the price of R chassis parts every year and the rarity of competent mechanics for these cars. They aren't that complicated but most mechanics seemingly have none of the equipment or experience to fix OBD1 cars anymore.

@Ben C34 @robbo_rb180 @BK @GTSBoy @PranK @Murray_Calavera  morning all I am in the UK. Thanks for all your replies. 
sorry for posting on your forum but the UK ones are shite.  
The person who built the engine is one of the best in the uk to my knowledge. I am not going to be using the 850hp on methanol. I’ll be using a safe 500/600hp. Won’t be thrashing it. Why because I want to look after it. Why am I buying it? Because who doesn’t want a skyline ?! The whole car is immaculate. Underneath paintwork everything. Can I add pictures here ? 
 

the main reason for the thread was. I wanted to know weather I’m going to spend every weekend in the garage or can I actually enjoy this car? will this car do 100k miles. If not what will need replacing. I not a drifter. Nor am I a crazy Driver. 
 

again thanks guys all responses are helpful negative or positive. Cheers. 

[Benrobinson]

Sorry that was advert. Haven’t brought the car nor am I selling it. I am going to view this week. 

[BK]

How much does it cost then ?
