BHP help?

[tomscott]

Ye but hasn't that 3.0l done 80ish k?

That would go against the mantra of having it from new, knowing how its been treated etc etc

The only ting this will be is a massive headache. Its not the same sort of project, if it was to make something more unique fair enough… But replicating a car you can buy for 6-9k…

As a long term serial modder I'd have to say the same thing as many on here.

Many moons ago I modified a 26bhp 1 litre Mini Mayfair. It ended up with an 86bhp full race engine, fully adjustable suspension, cage, buckets etc. When I took it off the road, it never went back on. I spent £££ on it over the years and still never kept up with anything past 1293. That was a classic too. I never got my money back and the car became so unreliable I was rebuilding the engine every few years.

I tried modding my first TVR, a 2.9 V6 and after doing a bit to it, I chopped it in for a 4.0 for a lot less than the cost of a Cosworth conversion.

I then modified my 4.0 adding a fair chunk of power and torque for a not inconsiderable sum.

Through all the years I have struggled to get insurance being a young driver of sports cars.

Seriously it is much easier to buy a better/faster car. I've given up tuning on cars and bikes, now it's cosmetics and a few little mods. It's heartbraking to let go of one car that you've put so much effort into (I know, try watching it catch fire and explode in a freak garage fire), but you'll soon forget it when you drive a faster car and then get to work re-installing all the mods.

On the tuning note do check out your drive train longevity, my mate runs a 450bhp TVR Chimera (Charged and cooled, mapped, etc.) The bottom end was fine, but the drive shaft and diff bushes were lunched in a month.

Johnny, just my advice :wink: Take what mods you can off yours and sell it, you have got a fantastic car that somebody will snap up, then the money you were going to spend, put that towards a 3.0 then put what mods you have back on and start again, thats what it is all about You will have the power base that you can then build upon and produce what i am sure from your threads will be one of the top cars on the forum
Oh and you need to get a coupe for it to be the top car :rofl: :rofl: oke: :fuelfire: :tumbleweed: :evil: :rofl: just about covers that

 

[domsz4]

serious link now if you could do this with an engine transplant then you would have an epic Z

is this of any help to point you in the right direction

I sort of agree with Bing if he wants to do it and keep it for life (as its a hobby) then good luck.

The only area i think he will struggle is maintaining it as he gets all the work done for him.. and even with the recent EML light he has... once you go FI you need to be able to pull things apart and diagnose them yourself without sending your car on a low loader every week.

Excellent motor - and he'll even post it to you :lol:

Aquazi - I thought the EML issue is really only prevalent with the 2.0 though ? Changing the engine, drive train and exhaust might get rid of that damned little light on the dash. Worth it for that

Tom - true with regard to the mileage of the 3.0, but we know these engines last for a long time. Not sure you'd ever find one with just 27k on it like Jonny's current one. Could it not be stripped downand rebuilt whilst it is out of a car such that everything is refurbed to extend its life ? Though I guess that sort of work starts to put the project back into the supercharger price bracket...

 

[Adamski]

80k is nothing for a 6 pot. And would likely be less troublesome than a 'charged 4 pot.

Hope JE listens to good advice this time. Otherwise we'll have another thread with the same comments in January :rofl:

The eml can be anything, 4 or 6 pot... Its prob just an O2 sensor.. But the point i was trying to make... If he wants FI he should be able to get a code reader and check what his eml light is... If he has problems with a fI he would have no chance to self diagnosing =$$

Im not saying there will be anything wrong with a 80k engine. But why put an 80k engine in a 27k car defies the point and we all know what the reaction would be as it has been from the other hundred threads on the same subject. Just buy a low milage 3.0l, cheaper more reliable and less stressful. At the end of the day even if you haven't had it from new small visual issues are so easy to sort for the average person mechanical ones maybe not...

 

[edd_jedi]

It's not even anything to do with money, the point people are trying to make is that even if money is no object, it's not a good idea. A supercharger will cost thousands, make the car far more unreliable, make it difficult to sell in future, and it still probably won't be as fast as a stock 3.0.

Selling the 2.0 and buying a 3.0 keeping the mods isn't the cheap option, it's the sensible option. I don't see anything on his car that would be impossible to move over to another car, even the new roof.

 

[domsz4]

i guess the only thing that would be a pest returning to stock would be if johnny has sold loads of bits. he will have to find an exact match for for the colour so he can swap the bits over.

 

[Anonymous]

RE the re map; I agree with what most people are saying as I got my 2.5 remapped and tbh it's made very little noticeable difference. It's a fair whack of money that I wish I had put towards a full exhaust system upgrade instead.

If you are going to keep the car and continue to modify it then the 3.0 engine swap or trade in for a more powerful motor sounds like the sensible option, but hey, modifying is not always the sensible option! A supercharger does sound pretty cool as well..!!

Changing to a 3.0 zed would have other benefits too. Better spec, sport mode to sharpen up steering etc

just swap a V8 in it. get your self a lot of money, get it to a good shop, and let them drop a bmw V8 of V10 in it. then you'll have the looks and the power.

I agree with Rusky...except for the coupe part

 

[sam1832]

Just my thoughts ....

Dont build something you can buy, 3.0 transplant waste of time just go and buy one and swap your mods probably cheaper and easier

SC on the 2.0 n46 block .... I wouldn't do it, for fear that you would soon be doing some sort of engine transplant
Drop in a bigger engine, get a 3.0i or an m

Just of note JCW Mini Cooper S runs on a supercharged 1.6 and produces 210bhp so can't see why you couldn't achieve similar bhp to 3.0 model with a sc

I think it's a false economy to tune the N46. It's not the most reliable engine, manifolds often crack etc and that's before you add forced induction. Plus, for the cost of tuning you could drop in a 3.0i which will run hassle free.

If the cost of transferring mods to another car worries you Jonny, think of the cost of fixing/rebuilding an engine.

None of us want to see a thread called "It went BANG" next year.....

Agreed - especially as Stevie.w has a 3.0L lump/box available that was known to be running well - it's not like an engine from a crashed car on eBay....
