Hybrid stock turbo: T04E or T04B?
Present setup: '89 stock turbo.
Future setup: an upgraded stock tubo with either a T04E or T04B compressor.
I'm torn between which setup to go with. I'm also not into reinventing the wheel. Those of you who have gone down this road, please sound off. I'm not looking for a drag setup, just a good (no, make that great) street setup. To be more specific, I'm looking for nice smooth lower end power, not something that makes power after 3 or 4 grand. Plus I don't want to spend too much. That's why I'll be happy with a hi-flo turbo and not a full turbo setup. I've already done a "search" on this but was unable to get the specific info I want. I'm kind of leaning to a setup like this
· T04B (Comes with TO4B Compressor Housing, Dynamic Seal and TO4 Backing)*
· Ported wastegate
· Modified thrust bearing
· Clipped turbine wheel
· 60-1 compressor wheel
· 360 degree thrust package
· choice of turbine wheels this place I might go with offers (t3 hi flow, 0 trim, 69 trim, or P trim) - I don't even know which one to go with yet
or a set up like FEDREX's:
· HT-18 Reman & Upgrade = Stage3 T/W 46/Trim C/W 360
· T04E-46
So, will a T04E housing clear a stock engine bay with a stock exhaust manifold? I hear yes and no. I want to hear from a person with first hand knowledge.
Basically I'd like to hear the pro's and con's of each to help sort out what I want to know. Also, if you know about the exhaust wheel trims (t3 hi flow, 0 trim, 69 trim, or P trim) that'd be appreciated. TIA.

BTW, I've got an '89 T2. So I'm dealing with the stock manifold and the stock turbo setup so far. The fuel issue will be be addressed with accordingly. I just need info on the compressor upgrade.

Honestly I don't see how a T04E compressor housing will clear the lower intake manifold.. My T04B compressor housing already touches the manifold.. I can get a bit more clearance if I cluck the housing a bit, but that would just present some annoying problems with the IC hose..

What do you think of a RB Turbo ? they are expencive but i know they spool up very quick.
The other thing is if you keep the turbine housing quite small and you dont go mad on the compresor it should spool up quick but at the end of the day you will struggel making a bigger Turbo spool up quicker than a smaller one.
You need a good balance of Turbine size to small and it chokes the engine to big and it takes a week to spool up.
I like the T04 60-1 .96 Devided with a RB core that spools up quick enough for me.
O yeh XS make a realy cool Manifold with a External Wast gate.

Maybe Jerk means good boost below 3-4k rpm? My limited experience is that the stock engine gains alot of power after 3k rpm even if full boost is achieved much earlier. I am interested in this subject too; just got an 89+ turbo I am considering upgrading before I put it on my rebuild.

you make a 1/2 inch spacer for the manifold and it would fit
see? 4" inlet, 2.5 discharge, 62mm compressor wheel, T04B compressor on stock manifold

I guess I should have been more specific. I don't want a turbo that takes beyond 4k to realize boost. Having good boost by 3k~4k for good driveability is what I want. I'm not into drag racing. If the power drops off around 7k or less I don't care.
Some of these replies mention a spacer being needed. This holds true for both the T04E and T04B compressor housings?
