I am sure this has been covered before but i cant find on here.

Im currently running EJ25 fully forged its an ODB just wanted to know what sort of power can the ODB handle.

Im currently running 370bhp and has been running good for just over a year but im thinking to raise it a little more maybe 400-450.

Cheers

 

500 is about the limit for an open deck safely mate,Jura is running an open deck at 490 without issue.

 

As above Ryan said,we are running OBD and we are at 490bhp,but as Neil@Slowboy racing said our engine can be pushed up to 550bhp

About the 2.5L,they're have thinner liners than 2.0L OBD,all depends on parts used and on the turbo what you are think to use

Thanks for the reply guys

Wiseco pistons
Manley rods
ACL bearing
ARP head studs
Cosworth head gaskets
Cosworth oil pump


Currently running AF20g but lookog to get SC46

 

I'd say you will be more than safe mate.

 

Also the heads has been fully re build the block also has all new seals.

6speed will be fitted next month.

 

As Ryan said be more than safe,SC46 will be good turbo or MDX321T(on yours I would try MDX321V),those two turbos will be mine choice


Jura

 

Thanks for the advise guys.

What soet of power can these 3 turbos can make? I know that SC46 can make pver 450bhp but dont know much about the rest of them.

 

MDX321T is 450bhp turbo

MDX321V is 500bhp turbo


Jura

 

Thanks Jura, where is the best place to get MD turbos?

Spoke to Duncan @RaceDynamix and decided to go for a MDX555-450 or 500

 

Both turbo's are similar as MDX321 and will be good on your build,both using same turbine wheel as MDX321 or LM4xx


Jura

 

But before any turbo upgrade im going to fit a 6 speed gearbox.
