dont flame me if its like a really stupid question, but i need to learn hah. im sure everyone was the same few years back

 

but, whats the advantage of having a single over a twin anyway? surely, on paper, having a twin turbo would be more powerful?

 

 

A properly ,matched pair of none sequential twins making X horsepower will be less laggy than a properly matched single making X horsepower. Twins are more costly, more complex and thus less popular. The difference isn't chalk and cheese but twins will definitely spool faster, it's just a fact.

 

I said my piece on single conversions and the true cost years ago, I now get confirmation I was right on a regular basis :(

 

If you have the budget, accept that even the best single jobs will never have the development behind them that Toyota put into things, and don't mind accepting things may still go wrong, they are great fun. Nailing a cheap kit on a knackered high mileage car and expecting things to work properly or for long is a mugs game, don't underestimate the cost. I have always said given a sound engine and car as a basis 15K is about what you should expect if you pay someone for a turn key job.

Whats wrong with it? mine drives like stock.

 

Mine too.

There are niggles, and I like to be involved in the upkeep, but I love my single and i've been through 2 stocks. The power is addictive when the car is set up right. VVTI makes it pull hard at low revs.... spent the week driving a 130hp diesel on the road and my t67 pulls harder at 2k in 6th than this derv mobile does at full power!

If you expect the car to have zero issues and have it run like a production car every winter's morning, then you should stay stock. But a car like mine for the price.. it's an increadible bargain!

 

We test drive a porsche 996 turbo yesterday.. it was smooth and well engineered but felt like a mondeo by comparison to mine.

Intresting thread.. Even if i do say so myself. :sly:

 

Comments that stuck out for me were...

 

I agree, no regrets from me, just probably don't use it to its full potential really, and kind of miss the lower spool up.

 

Thats the beauty of the Twin, and i feel i would miss the same after driving a single for a week.

 

Went back to stock turbos and I found my love of Supras again.

 

A stock based supra on BPU+ will be as much of a hoot as a single, and probably without the huge investment or the need to put in an aftermarket ECU etc.

Wasnt there a specially made Twin Turbo setup made for the supra that someone posted a few weeks back.

 

Was trying to find it but cant.

 

I am wondering, after BPU for those who are wanting that little bit more, without spending 7-10k for a proper setup, is there not a more subtle compromise? I know there is hybrids, but even them you hear bad things about.

There's always nitrous, but it needs installing professionaly. Probably getting the suspension, brakes, tyres etc well set up would be a better course of action.

Not if you fit a smallish DBB turbo, spool up on my GT35R was only 2-300 rpms later than the stock turbos.

 

No regrets here (well until some £$%^ stole it! :(), only regret is that I didn't do the conversion years ago.

Done two' date=' love them both. No regrets at all.[/quote']

 

Now theres a reply that put a smile on my face :)

 

Or is it more a case of, phew, im glad i can trust that this man has done it properly with care and attention to detail.

 

Hopefully i can put my own thoughts into this thread in the next week or so. But the general opinion clearly comes down to 'dont be fooled you can do it cheaply and cut corners, or you will be disappointed'

It hasnt been a trouble free single conversion for me despite spending a lot of money on high quality parts and workmanship; in hindsight I probably wouldnt have bothered due to the amount of funds that it has and continues to gobble up.

 

Having said that, performance wise it is in a different league and chalk and cheese compared to BPU for all the reasons mentioned above.

Good thread...

 

I'm sure like many on here I have dark thoughts of going (or buying) a "single" - especially after being at SupraPod on Saturday.

 

But I'm about as mechanical as my dog and I would only want a Specialist guy / company to do the work for me... so big bucks.

 

I see them on pistonheads, but I suspect it would take hours / days for a Specialist to go through the set-up to check if it was OK (if the owner would let someone - doubtfull).

 

I just can't justify 10-15K on top of the car, so I'll just stick to drooling over youtube etc.

 

Trouble is - none of the above stops me wanting one :(

I have just finished rebuilding mine, all the money is spent and is ready to enjoy now, the mapping is done to 1.2 bar, you decide how much further to go, I feel I am giving it away but I just lost my job so it has to go !

I hate you...

 

"the feeling" - it's started again, worse now I've looked at your thread :(

 

I'll try not to PM you.

 

Good luck with the sale.

I ride as well. Its a totally different drug IMO. Everytime i get on my busa, its just unbelievable. Especially if i leave it alone for a couple of weeks. BUT...

 

The car gives me another kind of mad rush. Its car has more drama, more of an event. Its too easy for the bike.

 

both great tools though;)

 

 

 

Agreed, but I've got sour grapes in one hand and the keys to my R1 in the other;), I never completed the project, but it was too expensive imho,

 

I dare say the feeling of owning one will be awesome, I was chasing that same feeling I got the day I bought the sup, Bpu just didnt hit it anymore, a ride in a few high powered cars did:d

 

I'm probably on the slippery path to killing myself switching over to bikes for the mean time, but I have to say, I've never felt anything like it!

 

I will say their not as cheap as first thought either, they have ate into my savings more than I would have imagined, disappointed in myself the money was meant for other things, but we all got to get our kicks from somewhere, and this gives it in bucket loads!!;)

Further to my original post, about not using it to its potential, i have now come to the conclusion that unless you have motorway, DC or very good A roads to drive on, you never get to experience the power of a single where it counts, i have mainly not very good A and B roads in my area, so its only quick squirts, and i am actually finding that i want more power now:(

I know what you mean by the rush difference between a fast car and a fast bike, two different rushes from a similar thing.
