Question Is this turbo to Big

I talked to Tom of Techworks last week and he spoke of a list of turbos that our setups (Techworks setup) would be compatible with. He's going to send the list since there was a bunch of sizes (VF series, Garrets, IHIs, etc) that I can't remember. Currently, I'm getting a GT17 setup. I'm not sure if he was speaking of just the GT17 setup or our setups as a whole.



Then I mentioned a Garret T3/T04E to him and I remember him laughing. I can't remember exactly what his comment was after that since I was at work and things where happening around me.



I currently have a rebuilt Garret T3/T04E sitting in my garage from a Ludespeed turbokit I had on my Outback Sport. I still have the uppipe and downpipe that may be able to be modified to fit if I end up not getting or selling the Techworks setup. Plus, I'm pessimistic and I can't see me receiving the Techworks setup until sometime in the summer at least because that's how things seem to happen when I get really excited about it.






So, is this turbo to big for an RX turbo? I know someone else here have probably used this turbo on their setup. What are the pros and cons of it (Lag for instance)?

I currently run a T03 on my volvo.. but its 9.8:1 CR 2.3 litre(up from 8.5:1 stock). I ran a T03/04 on my Saab, but again, it was a 2.3 litre motor.. Aside from your overall displacement being quite a bit less, the 7.7:1 CR is not going to help with the monster turbo lag you are bound to achieve.

You might have some trouble spooling the to4 series turbos but the top end is amazing! I have a to4B on my 1.8 and it spools at about 3800 rpm. So yeah there will be more lag, just make sure your using a .48 A/R exhaust housing.

Too big for me. There is no way you are going to be able to use that much turbo on a EA82T. It sounds cool in a mod list but if your engine is anywhere near stock I can't see putting it on.
You could sell it for at least three times what a used TD-04 take off would cost. And I don't think you'd ever need anything bigger than that.

Currently I've seen the GT32 turbocharger work damn well on 2L WRX's. This is turbo with a moderate compressor at just over 40 lbs/min, and a large hot side. Might be worth a try if you can make a real twinscroll header.

however, the problem with the RX motor isn't its size its the motors crap exhaust and intake paths in the head.

wow...out of all these responses, no one mentioned to actually read the compressor map vs the requirements for the setup? maybe this should be looked at first...


just my .00001 cents

Theres a simple explanation for that. A number of us are:

A) Familiar with a nuber of turbos, turbo cars and general characteristics required for them to function properly
B) Specifically familiar with the EA82T and specifications and quirks.
C) Familiar with Kevins application and requirements.

This is something I have been pondering for awhile, but I wonder how well a TD05 would work on an EA82T, with a little exhaust work of course? They seem to have pretty quick spool-up characteristics and if my memory serves me correctly, they move more air than the VF7 hands down. The hot side of the turbo housing is larger too.

Depends on the amount of money you want to spend I guess.. You talking TD05 16g?

I'm using a TD04 13G and its so much larger than a VF7 its not even funny. The great thing about them is that they're a dime a dozen.. The WRX guys just toss em..

No, actually I was thinking more along the lines of a TD05H 14B turbocharger. The same ones that came on 1st (or 2nd, I can't remember) Gen Turbo Eclipses. It is smaller than a 16G, but it is slightly, just slightly larger than a TD04. I don't know, maybe I will go with a TD04. I wouldn't want to stray away from genuine Subaru parts, even if they are made by Mitsubishi!!! LOL
