Boxman Posted July 11, 2012 Author Report Share Posted July 11, 2012 Oh and on a totally other note; does the engine + gt3071r even fit in he engine bay properly on a T5 exhaust manifold (a flowed one)? Link to comment Share on other sites More sharing options...
Zappo Posted July 11, 2012 Report Share Posted July 11, 2012 I am running a 3076R, it fits. Link to comment Share on other sites More sharing options...
850wagonT5 Posted July 11, 2012 Report Share Posted July 11, 2012 And Im pretty sure people wont expect the same HP from $50 cams vs $1000+ custom cams. As for the burnt valves, maybe you did go too far messing around trying to reduce overlap? Who knows? Lots of other NA cam users with no issues including myself with 1000s of miles of use. I ran the car too hard, too lean, for too long. Had a few "spirited runs" lined up with a few local V8 folk, and I wanted to make sure I won. 24-25psi, but a combo of too much overlap/duration and not enough injector got the head a little hotter than it would have liked. I'm not sure if I won or lost in the end. I beat the cars I wanted to beat, but after a few nights of that, I came out to the driveway the morning after and noticed a small puddle of green foam where my oil leak normally is. ...whoops. :tup: Link to comment Share on other sites More sharing options...
Martijn_B Posted July 11, 2012 Report Share Posted July 11, 2012 Boxman: are you not using a R manifold? No problems with the T3 by the way.@Zappo: Any reasons why to pick a 3071 or 3076? Link to comment Share on other sites More sharing options...
Zappo Posted July 11, 2012 Report Share Posted July 11, 2012 71 would probably spool sooner I suspect given the same housing. The 71 refers to the exducer size. The 76 would generate more HP, but probably not a significant difference. I am no expert though. Link to comment Share on other sites More sharing options...
Boxman Posted July 11, 2012 Author Report Share Posted July 11, 2012 @ martijn, i am using an 850 R manifold, by which i mean a manifold that looks like the stock t5 manifold on the ourside, but is actually a japanese flowed one on the inside. So still with one tube going over the others. There is also an S60r manifold i believe some people use, the one where all tubes go downward, and that should fit the 850 engine too. but i dont have that one. I dont suppose that will bring any problems? Link to comment Share on other sites More sharing options...

I run the S60R manifold, although it is modified for the turbo. The "R" manifold is designed to put the turbo in the exact same place as the older T5 manifolds. The modification I have is the raised ring on the standard Volvo manifolds has been shaved flat to allow a standard T3 turbo to fit. This also allows you to use the stock oil return line, at least on the GT turbos. Link to comment Share on other sites More sharing options...
lookforjoe Posted July 12, 2012 Report Share Posted July 12, 2012 You can use the MAF of an Audi S3 but it requires some soldering I think. You should upgrade the intake pipe from the airbox to the Turbo too. The reason is that the original intake pipe has a narrow bend that reduces airflow. Then I think we all agree that an AFR gauge is mandatory when aiming for 400whp. As for the N/A cams: Im currently running both, but will start my engine build later this week and will just use the intake cam. There is no point using a different MAF sensor with ME4.x. The limitation is in the EMS, terminal recorded flow is 231g/s. All you can do is change the HOUSING for a larger one (V90 for 2.75" ID, or Audi A8 for 3" ID - but any change in housing will require tuning, you can't simply swap the housing as the scaling of the maps will be off.

854TGA+ Posted July 12, 2012 Report Share Posted July 12, 2012 Oh and on a totally other note; does the engine + gt3071r even fit in he engine bay properly on a T5 exhaust manifold (a flowed one)? If you decide to go that route, I am no longer using that S60R modified manifold / I also have a 3" downpipe for that setup also available. When that manifold was sold to me I was told Cosworth did the modification. Link to comment Share on other sites More sharing options...

Boxman Posted July 12, 2012 Author Report Share Posted July 12, 2012 @854TgA: is that downpipe with a cat, ie is it road legal? If it is, i might very well be interested @above me: what about the syncro's? My gearbox is fine atm and new syncros are no longer available right?

Boxman Posted July 12, 2012 Author Report Share Posted July 12, 2012 @854tga: okay so what kind of kat would fit on there? Any links? Available to the netherlands as well. So then there are two options: - get your manifold + downpipe and a catalyst (this should be a direct fit to my stock exhaust system, right?) - get a custom downpipe built here in the netherlands for my current manifold How much would your option set me back? Any pics? Link to comment Share on other sites More sharing options...
Johann Posted July 12, 2012 Report Share Posted July 12, 2012 - get a custom downpipe built here in the netherlands for my current manifold An 18T Ferrita downpipe can be made to fit pretty easy if using the ATP ultimate gate with a V- clamp.
