The master powers i have seen have worked really well with no problems and make really good power . I see on the pics u have a cheap china made wastegate. are you sure these turbo's are genuine ?
looking for an engine for a conversion . Needs to be low k's and engine must be in good running order. Also need good panels on the half cut. eg... bonnet , bumper, grill.
If no half cut a r33 gtr engine will be ok .
HKS pistons have gone really cheap in the last couple months. Bit iffy on the arias pistons. I have them for my rb26 but have seen alot have ring problems . As for rods the pauters are awesome getting cheaper too . www.pauter.com
