i have a mini me right now..and i want to boost it..will a t 25 be ok to boost it? what recommendations are there for boosting the high compression mini me...also can i lower the cr of the mini me?

 

t25 has an internal wastegate set at 10-12psi from the factory..
If you get that turbo you might wanna think about getting a different spring for the wastegate to lower the boost....
You can stack headgaskets to lower the compression..I dont know how reliable it is but People have done it before..

 

t25 is an awful small turbo. i wouldnt use one on anything bigger than a dpfi 1.5. since youre a vtec 1.6 that will see what, 7500, 8k? i would go t3 .60 and up. the rod to stroke ratio of the d16's makes them lively on the bottom and taper off up top. a larger turbo will be less restrictive, create less reversion, and pull right to the redline. the car will feel lively from top to bottom. a t25 will be instant boost jerkiness that chokes the exhaust flow on top and kills torque.

This just sounds wrong on....................5 different points.

1) T-25 is fine, you won't need anything bigger for now, especially with the higher compression ratio.

Overall, this turbo is a great turbocharger if you like incredibly fast spooling turbo's. But does not pull nearly as hard at 12psi that a 14b does</TD></TR></TABLE>

2)Where is the huge difference other than 100ccs between the 1.5s and the 1.6s? You make them sound as if they are world's apart.

3) You say the 1.6 will be seeing "7500-8000" when in fact the 1.5s are able to do this easier due to having the BETTER rod-stroke ratio between the two. How does the rod-stroke ratio change when the power is made?

In fact, increased backpressure may lead to backwards flow or "reversion", where the exhaust gas travels backwards into the combustion chamber and dilutes the fresh intake charge at cam overlap. At the very least, it slows exhaust flow velocity or energy and prevents the creation of a vacuum for scavenging.
</TD></TR></TABLE> A proper turbo setup will not have reversion (as far as I can say with my knowledge of exhaust flow) as the exhaust does not have a chance to flow backwards. It is continuously pulled toward the turbo and pushed out of the cylinder by the intake charge. You also act as if the T25 will "jerk" the car around as if it has full boost at 10RPM. Yes, I said 10. How will that choke the exhaust flow and lower torque? Do not apply Naturally Aspirated Logic to a case of Forced Induction

I agree 100% with dr_latino999 on this. That T-25 will be fine. Spend your money on GOOD fuel management.
