Ian C Posted November 29, 2006 Share Posted November 29, 2006 On a manual I wouldn't settle for anything less than a 67, period! Yeah but your quarter mile times would suck with a manual -Ian Quote Link to comment Share on other sites More sharing options...

Sean1933 Posted November 29, 2006 Author Share Posted November 29, 2006 does anyone know if the PHR kit is better than the Boostlogic kit? PHR seem to be more expensive than Boostlogic, and MVP seem to rant on about how great it is if you want "the best"...but what does everyone else think?

adi2009 Posted November 29, 2006 Share Posted November 29, 2006 I think the general opinion is that PHR kits are about the best in quality, probably a notch above BL. However, I havent really heard of anyone complaining with a BL kit. Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted November 29, 2006 Share Posted November 29, 2006 There are a LOT of different opinions on BL vs PHR, it's worth a search. Quote Link to comment Share on other sites More sharing options...
8secSupra Posted November 30, 2006 Share Posted November 30, 2006 The Boostlogic series are Garrett cores, and very nice they are too. Still haven't heard of a BL tubular manifold cracking I don't think they are that el cheapo. Other manifolds may vary in quality... -Ian You wont hear of that, as its not generally made public. I've seen a bunch of them myself, one even on Dusty's personal car before he wised up. We use the HKS manifold, never cracked, never warped, perfect fitment, and lifetime warranty. Of course I'm pro-PHR, but hey, you get what you pay for! Quote Link to comment Share on other sites More sharing options...
8secSupra Posted November 30, 2006 Share Posted November 30, 2006 I agree 100% with the above posts. For a manual 6 speed car, the 67 is the way to go. For an auto car, I'd stay with a GT60 or 61 myself, its much more fun. 700 WHP on any car anywhere is almost impossible to put down. A quick-spooling smaller turbo that makes a wide torque band is much more fun to drive on the street IMO. Quote Link to comment Share on other sites More sharing options...

Bit of pay back for the DBB thread there Ian Like Ian said, I have never seen a BL manifold crack, I have however seen a few HKS manifolds crack, including Leon Green's twin manifold if you want to check Jarrett.

Leave him alone, Terry, he's helping me with the Knock Amp I've bought and fitted a BL kit and it had everything I needed in it. I hate 'kits' that don't actually have everything you need... I mention the PHR staged kits because I've heard that it's good quality, it also has everything in it that you need, and I know of a few people getting good results with it. If I had to do it again I'd go for the BL kit again simply because I know exactly what's in it, but if anyone waved a PHR kit at me I certainly wouldn't turn my nose up it. As for the cracking manifold issues, well, I guess some may crack and some may not on each side of the fence, but more stay intact than crack. Perhaps Leon and Dusty aren't the best examples for long term durability -Ian Quote Link to comment Share on other sites More sharing options...
Nic Posted November 30, 2006 Share Posted November 30, 2006 Does wrapping the manifold increase the risk of it cracking? Quote Link to comment Share on other sites More sharing options...
Alex Posted November 30, 2006 Share Posted November 30, 2006 Does wrapping the manifold increase the risk of it cracking? I would guess not... Cracking IMO would happen IF it's not cooled properly and if you tended to drive down pot holes Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted November 30, 2006 Share Posted November 30, 2006 Im personally using a cast manifold for that exact reason nic, got most of teh kit from arnout now including custom DP etc...I dont know why more folk dont go down this route, for out and out drag power I can understand a tubular header would be more beneficial with flow etc but for a 58 - 67 type turbo I think a solid cast manifold would be a great idea and would allow for an increase in spool as well + no cracking issues Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted November 30, 2006 Share Posted November 30, 2006 Here is a very low mileage, but track day used, expensive, Greddy Trust stainless tubular manifold for an RB26 Skyline engine. It's had a butcher attempt to weld the various cracks, but even an aircraft certified welder would only make the repair prettier, it still wouldn't last, due to carbon inclusions. It's cracked because the material is poor, the design is crap, and there is zero support engineered in for turbo or wastegate. The other pics show my same dummy engine with a cast manifold. Which looks stronger? A cast manifold can have good runners and be pretty efficient, in fact they keep heat *IN* better, which is good as it keeps the gas speed up, as they are hefty. They can still crack, and do, but usually have many many times the life of sensibly priced tubular ones. They aren't shiney though, so people shun them. Stainless ones don't stay shiney for long though! You can improve a tubualt manifold by engineering in a cradle with rose joints to take the weight, but still alow expansion and contraction movement. On race cars you can use slip joints, but they can blow when cold, so not good for a road car. Inconel is bullet proof if used in a good design tubular manifold, but it's very expensive. Last one we had done was 4k, and that was with astainless manifold to copy, not a clean sheet design. It hasn't cracked though, and has done many hours on a dyno and a lot of hard miles in a car, on the road and track. http://www.newbury-house.com/trust/trust.html Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 30, 2006 Share Posted November 30, 2006 Very nice Chris....are you having it heat coated I had it cerrachromed, but it'll probably come off. I had another done in flat black, that should stay put, but isn't as pretty. Quote Link to comment Share on other sites More sharing options...
Sean1933 Posted November 30, 2006 Author Share Posted November 30, 2006 Chris can you fabricate the DP required for the Arnout manifold? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 30, 2006 Share Posted November 30, 2006 Chris can you fabricate the DP required for the Arnout manifold? Given the car with manifold and turbo fitted, and the exhaust fitted, yes. Would need trailering. I thought Arnout offered a downpipe for certain turbos?

Wez Posted November 30, 2006 Share Posted November 30, 2006 is this based on the turbotechnics one Wez! how did you find fitting etc Not sure, I know it does not have the same small wastegate issues that were associated with other cast manifolds. Fitting was easy, I fitted my single over a weekend then had Hayward and Scott fabricate custom downpipe and screamer. Quote Link to comment Share on other sites More sharing options...

I thought Arnout offered a downpipe for certain turbos? Thats a long way to trailor, but im only looking at my options. I have been told that the Arnout manifold cant really flow enough for a T67 DBB. What are your view on this? Quote Link to comment Share on other sites More sharing options...

Sounds good, I was going to do the same with Haywood and Scott making a custom DP but went for Arnouts Kit and DP prototype! SimonB used it with no issues so fingers crossed! Did H&S need your car down there to fab a down pipe for you Quote Link to comment Share on other sites More sharing options...
