Stock 33 Turbo Substitute

[skidlineTodd]

looking for some advice.

Recently blew both sides of my stock r33 turbo (ceramic dump side, nylon compressor), which destroyed my engine etc etc now my life is ruined..

Anyway time to rebuild on a budget, have managed to find everything i need for an affordable price but this would mean the turbo that would go in would be the same thing that blew up on only 10psi with pretty much standard everything. note: replacement stock turbo is in perfect order but has 130,000 kms on it..

How do i either make this turbo more reliable, or can anyone suggest a replacement turbo that would be more reliable, something of simular size as i cant really afford a retune at the moment. preferably the cheapest and most reliable option (yes i know that doesnt really exist)

cheers

2nd hand highflow is the only cheap and reliable choice. You need to keep the same basic turbo to make it trivial to bolt and plumb up, but get rid of the fragile bits.

If you want to buy something new, then I would suggest the following plan. Sell the good R33 turbo you have just bought. Put that money, plus some more, plus the core of your dead turbo in a box and send to Hypergear. His highflow job is only $860. Well worth it.

I agree with GTS boy. however if you run the HG highflow you have to drop boost a bit below 10psi on the stock ECU.

This turbo moves more air for the same boost which means that 10psi on the new turbo means more air than on the stock turbo. This WILL give you issues on the factory ecu.

I ran this turbo on the factory ecu while I was waiting on parts; it wouldn't run well on anything higher than 8psi

edit: just remembered I had MAJOR creep issues from 5k RPM and upwards. that turbo on the factory wastegate physically couldn't run LESS than 12-13psi up top

or you could buy my toshi remapped ECU and run 0.8 bar until you can afford a new ECU

[hypergear]

can definitely make it run less then 10psi with smaller compressor and turbine profiles. Depending on what the plans are, if injectors and ecu are on the list then have the larger profile and don't thresh it till the the mods installed and car tuned.

thanks guys,
would everyone all agree not to buy a brand new Chinese branded one? at this stage i think it would still be better than a used standard one

Do not buy YumCha turbos.

LOL... stock ones were designed to last a few hundred thousand kms in factory form, i.e. stock intake, stock boost, stock exhaust

The dimsim ones were designed to be used as DIY jet engines or door stoppers or bolted to Hondas.
