BoostdR

Kyle pointed out I would have most of these issues as it was the only way to make a decent collector. The idea of this thread is to identify a step by step installation guide and to outline the outlay versus performance gain. They will be heat wrapped never the less. There close proximity to the rocker cover and hard pipe we induce too much radiant heat even ceramic coated. Matt Matt

My exhaust goes from twin 3" into a single 3.5 into a 5" muffler. I ran twi3 3" side pipes at the track and my boost rose to 2.3bar from 1.6 with no other changes. At 450rwkw+ twin 3" is the only way to go. A sinlge 4" flows 12.5% less than a twin 3" but without the associated cost... For interest sake a 4" has 20% more area/flow than a 3.5"....

Just another thought....my bonnet clearance will be awefully close with the RB30's height considering the timing cover doesn't fit under...from what I can see it actually won't fit with the height of the top pipe. Will have to have a closer look at that.

I will be running heat wrap on the manifolds and make up a deflector sheild with tags that are held on by the hose clamps in that area. Not interested in reinventing the wheel -->Cast alloy pipes are a pain to weld. I may be able to get some more clearance by rotating the rear turbo compressor housing. Pretty sure its already close to max clockwise rotation available however. Now I have to decide what to do with the pipes. Crinkle black with black silicon or as is with black silicon...

its a tap

I had to enlarge the flange holes to 9mm to fit correctly. The front Dump pipe O2 sensor also doesn't fit as it fowls on the manifold My hard pipe kit does fit, I am also using an Apexi Z32 adaptor pipe kit...but will have to check if the filters still fit in the engine bay

Now that I have drilled out the manifolds I will be able to bolt up the turbo's and dummy fit up my hard pipes. I reallllly hope they go on without the need of modification. Will let you know....with more pics of course. My power steering resevoir will need to be moved however.

So the 45's come out of each turbo(needed to clear the actuator rod) then both lines go into the Tee(one with a straight connector and the other with the 90) Then out the other side of the tee with a straight connect to line to another straight connecter to the barb adaptor and into the OEM 10mm ID pipe. I will re route the original hard pipe boost and vac line with some silicon.

I have drilled the manifold flanges out with a 8mm bit. Will see how they fit on the studs when I get home. Should be fine if the holes are in the correct position as 8mm is a close fit. Here is the list of fittings I ordered to do the Water lines. I already have M14x1.5 to -6AN adapters in the turbo housing so you would need 2 of those to. I got mine from MTQ turbo's here in Adelaide

Update I have ground about 2mm off my head tabs, now has enough clearance for the manifolds with heat wrap. The manifold flanges are also threaded, why I don't know. They will have to drilled out to allow the turbo studs to poke through. I have ordered some black braided stainless line and AN fittings for the water lines. I have also found a -6AN To 3/8 barb to join at the back of the Plenum. I will post up my order list soon. Matt

The turbo flange level (height) when mounted is 4mm different. One is higher than the other.

1. clearance to the strut towers not an issue 2. No chance of fitting the twin turbo pipe. The hard pipe kit I have routes differently to the OEM..away from the rocker cover 3. GTRS 4. Front pipe is meant to be a direct fitment

should be .8mm per turbo. non ball bearing is bigger

Yep. 6boost collector is sex. Results in a couple of weeks

The oil line banjo bolt that screws into the block has M on it and a internal restrictor already

The OD is ~42.5 same as my stainless mani's The also are ~1.7times longer Any gain will be amplified at my power levels so we should be able to see and get a accurate % for others to make a eductated decision if the install hastle and cost is worth the effort

I have pulled my motor out to install some 6Boost Manifolds. I have found some issue's, most expected. -OEM water and boost hard pipes that run beside the rocker cover don't fit -OEM twin turbo pipe doesn't fit. I have a hard pipe kit here and will update you all if it works -Manifolds aren't even. 4mm out. If I hold one up and then tighten I can get it down to 2mm. Not to bad but I hope my Front pipe fits ok -Both manifolds just foul on the head. I will have to grind the head tabs down as I also need the clearance for heat wrap There is no doubt these will make more power with better spool over my stainless items. I will be on the dyno to confirm Matt Pictures tell the story:

wow, good price!! Great pistons to

I still have it and willing to post $100 plus postage Cheers Matt
