Thread: Think I went with too big of a turbo...

Oh I believe him, it's just other folks tend to jump in and start shouting that throws everyone off.

Now onto the hard part... finding used VET cams in the states.

Can Greg order them?

Yeah, sounds like $550 from Japan. I can hold out for something used and state side.

Hit him up and see if he still has them.

Already did, he traded them already

Reading through this thread and Coheed's thread has me wondering if there could be a difference in log manifolds from brand to brand ie. runner/tubing/weld el diameter and length, heat transfer properties due to different materials/thickness, wastegate placement or something along those lines as it does seem that you two may be experiencing reversion. Could it possibly be something that could be minimized through ecu tuning? The reason that I am wondering this is that I have seen a log on a VE work and I don't think that his turbo is so small that it would be the issue. Vadim- how do the specs of your turbo compare to a t3 super 60? The reason I ask is because I know for a fact that turbo did well with a log manifold with stock cams and you could definitely notice a power change when the cams switched. This setup was in the 360-370 whp range at 14lbs (don't remember exactly but the car ran great and didn't have issues at that boost level) Most of the other log setups I have seen were T3/T4 hybrids but I don't know the exact specs. This has me wondering what the difference could be. What brand log manifolds are you both using?

Here is my turbo specs:
Precision PTB003-5431 CEA (Billet Wheel)
This Entry Level unit features the following:
• CEA (Competition Engineered Aerodynamics) 54mm inducer compressor wheel
• "E" compressor cover 3.0" inlet/2.0" outlet
• T31, 76 trim turbine wheel
• Turbine housing options:
- T3 .63 A/R with 5 bolt discharge (without wastegate hole)
• 360° journal bearing system

Very good catch on the Log manifolds, not all logs are created equally, or designed equally

I have a Protech Log meant for the DE's, I had to drill out the bolt holes and attempt to widen the exhaust ports. The location of the turbo is towards the right, right by the 3rd and 4th cylinders.





Exhaust port shot:




Now if you have a log that looks like similar to these two, then you have a bit more of an equally crappy flow on all 4 cylinders.

Have you thought of mixing different intake and exhaust cams.

I am now, but the thing is, I'm not wanting big power so pending $800 on two sets of cams just to pick in choose is kind of out of question.

Maybe go 20v cams.

I am not 100% but I think you can dial out the overlap as the low lobes have a little overlap in them. maybe someone with an fsm can post.

And you also have a big cam if you decide to upgrade later.

On the subject of second hand vet cams. I let jp on here borrow a set from me ages ago. I have not heard from him in ages though. I would be willing to sell them if you can arrange it.
