Ok So seriously considering a turbo build....

But a few questions id like honest answers to

1. Will I need to rebuild a turbo engine more frequently than an NA
2. Is a correctly setup Turbo just as reliable as an NA 
3. How much power is too much for a daily
4. Could the power figure above be achieved NA
5. I have only driven 998 minis should I try 1275 before I go turbo?

Thanks

1 not really, you dont need to rev a turbo lump like an NA one so as long as your not trying to make massive hp its not an issue

 

2 yes, again as long as your not going mad its very much the same tech, your just not spinning it as hard, just keep an eye on temp and fuel mix with an AFR gauge.

 

3 how longs a bit of string, realistically 100hp is penty, but i know lots of people that end up with 150hp cars they frive most days

 

4 depends, but probably not, realistically a reliable daily NA car will be limited to about 80hp otherwise you end up with a mad cam, turbo wise you only ever use mildish cams tso you end up with somthing around 100-120hp that you can possibly wind the boost up on to 150hp maybe more. some run upto and over 200hp

 

5 probably a good idea, or a 998 turbo conversion is realistic with 100 hp

Can't see a power figure above, but perfectly possible to build a turbo daily- doesn't even need Iveco badges.

 

As much depends on how you use it, unlike a top bhp n/a engine it'll behave much as it does now in normal road use. Drive it hard from cold and smash it through the gears with loads of wheel spin and even a modest turbo is going to break soon enough.

LOL at the iveco badge!

my 1293cc motor before supercharging was getting 95 hp at the fly with just a swiftune sw5 cam, K&N, maniflow and RC40 no cat

Assuming the rr was accurate of course.

I'd honestly say that if you want a reliable daily. Don't go mad with boost!
I'm not havin the best of luck with my turbo mini. Although I did play with my knob and was running 20psi....Boost is very adictive 😂😂

As with hubba hubba, my worked 1312 with sw5 gets 97 atf, and think this is the sweet spot for a fast road mini, daily. My other one has 110 atf, but way more fussy on the road and to drive 'fast'.

Assuming the rr was accurate of course.

It was at Aldon Automotive, so I would think so.

If the engine is built properly, then it will last. Same with the gearbox but you need to work out what you want from the car. Putting more power through the gearbox is going to inherently cause it to wear quicker if not looked after with regular oil changes and some mechanical sympathy. If you want 140/150bhp+, start looking at straight cut gear sets. I'm having my box rebuilt as new with Guessworks with the standard helical gearset, but I don't intend for mega power.

Sorry but my childish sense of humour made me laugh out loud at this

[jt19]

Haha I don't know what power I'm running but at 20psi it certainly went well!
I'm running straight cut drops and a straight cut gearbox. I drained the oil out the other day and there was a bigger than normal sized lump on the magnet.
Engines coming out again lol
