B16A2 Turbo - Choosing Parts


all depends on how high you rev and the size of the turbo. the bigger the turbo the more lag therefor it shouldnt do any damage at low revvs. if it was a small turbo it would take less exhaust gasses to spin the turbo up therefor it would boost at a lower rpm and make the turbo over spool causing damage. i would say you where both correct but all depends on tubo size :)
 
will see not sure if i wanna spend 6k on the b when i could drop a k in for the same price
 
but if you drop in a k you wont get the thrill or power you would from a turbo.

even if you made a moderate b16/b20 n/a they are still more fun and suprisingly fast, my original b20 only made 154whp and 121 ft/lb and that was neck and neck with a 350bhp MR2 on the 1/4 mile.

I just think its alot of money to put a k series in an ek, dont get me wrong its different to see, but i still beleive the b series was made for the ek.

but at the end of the day its your car and thats why it is called "customised" cos it is unuiqe

Even if you was to drive the car around carefully ? Sorry but i can't see it been a problem unless the guy drives the car hard. I've had a boost pipe come off on mine before and i've drove it around for a week with no problems. Its certainly something i wouldnt recommend to someone, but i still can't see it causing a turbo to fail unless he was driving it around at full throttle. I just can't see the gas flow been enough to over spin the turbo at light throttle/load.

thats was i was trying to get across, on partial throttle the speed of the exhaust gasses at 3000rpm will be the same wether the boost pipe is connected or not, and surely the turbo spins hell of a lot faster at 12psi full throttle than partial throttle at 4000rpm
 
Hey guys, sry to bother you but how can you tell what's the best for your tuning when talking about wastegates.....38mm/44mm?
sorry for my english mates...cheers ;D
 
I'd say bigger is better... unless someone can tell me i'm wrong and why ? From what i understand there's no downside to running a bigger than needed wastegate.
 
Absolutely bigger is better if you want to run a large size turbo on low boost without creep it's a must. I have had my fair share of boost creep issues and only way to solve it was port the wastegate.

Why fcuk about though? Spend cash on a tidy set up only to skrimp at the last hurdle for what? I dont mean it physically will go bang but will knacker it no end. Why would you drive around for a week with a boost hose disconnected?
 
I know what your saying and like i said its something i wouldnt recommend and its not just the turbo side of it as the engine will be sucking crap into. It was more the over spin and going bang what i was replying to. I do agree with you that its not a good idea, for the turbo and engines sake and that it will naker them both up over time.

I was just been lazy by the way. I should have put the hose back on really as it wasnt as though i never had the time.... I know lol....
 
im going for 5k budget ....

just dont know what to do...

turbo on stock internals well for 5k i could probs get a decent engine build too.

Full motor Build

or just a kswap ....

or maybe b18c6 with turbo for 5k i could manage it

it's going to be a full blown track car when i've finished so just dont know wich route to go down ....
