BoostdR

Seat of the pants results Makes 1bar by about the same rpm, having said that it is noticeably more responsive from 1000-4000rpm. It makes 1bar just after 4000rpm however goes from 1bar to full boost in a few hundred rpm savagely. The motor also wants to rev, where as previously it would trail off around 8000rpm. I had to drop the boost to 1.4bar as it's maxing out my 1000cc injectors. Will get some 2000cc for the dyno The hard pipe kit has helped compressor surge, it still surges however is alot less and happily revs through. Matt

Started mine up today with the 1.1mm restrictor and STD springs in my Reimax pump. Runs 6bar cold now at idle. 25psi less than before. Plenty of oil splashing around in the cam cover. Matt

First start up, a few things stil to be finished Sounds very sexual, quite different to before Oil pressure was exactly what I was aiming for, 6bar(max). 1.1mm restrictor, std springs in reinmax pump http://s1107.photobucket.com/albums/h388/boostdr/?action=view&current=fc70deb2.mp4

Second, The alley bolts are to short.. very very easy to strip the thread. Will need to get some 5mm longer.

ok, first issue...the rubber O'ring seal is to long. lol

got the Plenum today, Quality looks pretty good considering some of the cast alloy kits I have received from ebay.. Will get a pre and post dyno

Thanks for the kind words =) I had to finish a 32GTR I had here today...took longer than expected so I have no updates for you. I will get a some more pics. Makes more sense than my ramblings! Matt

Front pipes fitted up ok. I have modified the alloy hard pipe rear turbo inlet. There is about 5mm space from the front turbo wastegate and 10mm-15 to the strut tower. I also had to grind the upper suspension bolt for clearance as it protrudes into the engine bay by about 15mm near where the power steering resevoir is mounted. This has to be moved also. looking forward to startup tomorrow. Matt

SOLD

ProAction spares on regency rd, Adelaide

I did have compressor surge before....only when boosting in a low rpm high gear. I feel the pipe kit will help this as I was still using the twin turbo pipe. There are also alot of variation that could effect my rear turbo inlet pipe position. Rb30 sits the head higher Engine mounts position in the slots Cast alloy hard pipe accuracy. So if the manifolds are out a smidge and you used the standard rubber inlet pipes you wouldn't have and issue. Just very hard as the rear turbo outlet stops you doing that. More findings today I'm sure. Matt

Engine is in. Rear turbo inlet pipe fouls on the Strut tower.. I gather the manifold sits the turbo's in a slightly different position to std. More custom work required. The Gearbox was also insanely hard to get in with the rear head drain...was hard enough with the Rb30 and sump adaptor which stops the motor tilting down as much. Its a pry bar job now. Matt

I had to trim my N1 bumper vents and remove the mesh to fit. That was all. May oil cooler still fits in between Matt I had a trust cooler and went to ARC. will never go back.

Why hasn't this sold yet! I have the same cooler. 534kw and counting.

Putting the other spring back in with a .9mm may end up flowing the same as less pressure with a larger restrictor. All a balancing act. I have an rb30 so it doesn't get revved as much meaning I am a little less concerned about oil foaming in the crank. Which is why some workshops swear by high pressure. Matt

I'm running STD dual springs with 1.1mm restrictor....

As Kyle from 6boost said, it was the only way to get a decent design. Worth it if the gains will be what I expect. Only way to get ahead of the pack is to go outside the norm..just gotta make the right selections Matt

Haha, there gloves.

Some more teaser pics, I had to order some more AN fittings for the turbo water lines. Would have been easier with some barb fittings and rubber/silicon hose but oh well. Matt

Still Avail

some twin 3 to 4" here for $50 Ebay link

Will be for clearance. The gab in between is needed to actually get to the inner nuts, plus the chassis rail contains the outright size of the outer pipe.

I currently have 2x3" into 3.5" Makes 455awkw. I put twin 3" side pipes on and it makes another 80kw If you can pick up a Apexi N1 dual, it would be a simple mod to run twin 70mm. having sais that a single 4" has about 10% more flow over twin 70mm pie x Radius , squared = area of a circle(pipe)

pull the head. Skirting around the issue is just wasting time and possibly risking a motor. I procrastinated for 12 months trying everything and eventually realised pulling the head was what had to be done.
