OK I have a sleeved h22a with wiseco pistons eagle rods and its dyno tuned on the Hondata s300. It makes 430 HP on 12 psi. My old Garrett Turbo overheated and the shaft broke right at the exhaust wheel. The Turbo was p/n 715583-5006 it was a .63 my question is. My buddy gave me a new Turbo and its alot smaller. 50 I believe. Will this Turbo work with the tune I have or am I gonna have to get it back in the dyno.?? Thanks any info is appreciated ...

 

different turbo u need a new tune ur tuner should charge much to retune the car

 

50 a.r is going to kill your top end some... H22's love a t4 housing

 

That motor needs a 61mm T4 snail and a retune.

Do it now.

 

I'm going to order the same Turbo I had. This one is just temporary. Thanks for the input. It seems to run fine under boost. The afr. Still seems good

 

It works, but you're still running rather rich because its not converting the same level of airflow. but good luck to you.

 

this

 

at the same boost levels ur going b flowing a lot less air so it should be quit a bit richer

 

OK so once I order the same Turbo I had and install it I should be good? Someone told ne that I could throw the original tune off has anyone heard this???

 

If the turbo is exactly the same then NO. Drive the car around sensibly with no boost untill you have your new turbo fitted to stay on the safe side. You've obviously spent a lot of money on the engine and it would be a shame if something bad happened.
