I ended up with a 20g and built internals on an sti v3 running 1.75 bar and its fantastic. but you get used to the power and now am looking to go bigger after 4 months.

tell me about it! no matter how much power you have you simply get used to it.

Wheres the best place to buy a TD05-18g from, Iwas hoping to get one overseas and save a bit but they dont seem a common as the vf34

Also Can the turbo be installed with standard ECU and upgraded at a later date?
thanks

Jon: How on earth did you get 1.75 bar!
Most we could map-in was 1.5/1.6.

I want to find the best place for a roller bearing 18g. I do not think AndyF does a roller version(?)

Please post if you find a good place.

To be honest I dont know I have sent andy an email asking him to comment.
I am running some logs tommorow with the datalogit to see what is going on.
After he mapped I pulled the heads and replaced the gaskets as the heads had "creaked" under nitrous. It turns out the head gaskets had been put on with silicone a big NO NO.

Once the car was put back together last week we took it out and got these results, we made a few other changes to the inake and catch can setup but nothing major.

I must say the car feels much faster than before the gasket change.

I will let you know the log results when I get them I dont know if running 103 octane gas in the car makes a difference?

I think that is the answer.
The better fuel will allow the map to be more aggressive (I think!)

Anyone know where to get a roller bearing 18g?

I'm not convinced there is much difference between the sleeve and roller bearing turbos. With respect to the IHI range, the only real way to telll if you have a roller bearing version is by the sound on rundown. Its not like the roller versions are really quick spooling in comparison.

Jon - thats the boost i would have expected to get with the wastegate duty we were running on the day, I mentioned at the time that I thought something was holding it back a bit, hence all the exhaust/induction experiments. It would be good if you could send me a datalog.

Well mate I plummed for the 20G then changed to the 18G for one reason and another. Last delta dash showed power was 392/350. Not too sure how accurate but certainly quick.

reano i went the 20g route you can see results and spec in my scooby part. but to be honnest if i was doing it again i'd have gone md321h more money for turbo and injectors etc but your looking at 400bhp and 380lbft
