MaTTSuN Posted March 24, 2013 Share Posted March 24, 2013 Well the time has come to swap my stock T3 with the holset i had kicking around I've re-drilled the mounting holes on the turbo, broke a few drill bits but surprised how easy it was to drill Ive read that some guys needed to put a spacer to clear the manifold.. looks like mine is fine. its tight but it clears fabricating the waste gate actuator from the T3 to fit on the holset...then i ran out of steam for the day when i couldnt find a part i just had hehe Matt Quote Link to comment Share on other sites More sharing options...

B. Whisky Posted March 24, 2013 Share Posted March 24, 2013 What's the deal with the welds on the manifold? Quote Link to comment Share on other sites More sharing options...
letitsnow Posted March 24, 2013 Share Posted March 24, 2013 I absolutely needed a .5" spacer for my HY35. I'm in a similar place in my install, but I think I'm going to go with an external gate if funds allow once I get around to it. Quote Link to comment Share on other sites More sharing options...
big-phil Posted March 24, 2013 Share Posted March 24, 2013 The Holset feels really good compared to the stock T3, looking good Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted March 24, 2013 Author Share Posted March 24, 2013 B. whisky the welds on the manifold are because i needed to straighten it a whole back, i cut it and bent it back " i knew someone would pick up on that" Letitsnow: I might have a friend with an extra external waste gate lying around, I wont fully install until i have confirmed with him. I really want to run a screamer pipe, they sound amazing. I guess the HX35w is a little different. I have an HX40 as well but havent test fit it. Big-Phil Thats what im looking for, i pulled everything apart to fix exhaust leaks but found the T3 had to much shaft play. Time to swap the turbo i had in storage for the last couple years... I know you have had a few different set ups but do you remember the difference in spool time to the T3? Also do you have an old Map for the Holset Im running megasquirt as well. Been following your builds love your RB30 Matt Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted April 8, 2013 Author Share Posted April 8, 2013 a little progress i got a tail waste gate from a friend so i had to use that it had 2 springs a 15psi and 7 im going to run the 7 for now then switch to the 15 excited to see how she runs with a new turbo Quote Link to comment Share on other sites More sharing options...

Just to make sure everything is working well before i change anything. Matt Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted May 3, 2013 Author Share Posted May 3, 2013 well after doing some hunting for a vband that will fit my HX35W and not finding a good solution. I measured my HX40 to find that the Vband is 3" !! i have a 3"vband that fits this Im going to install the HX40 so i can simplify my exhaust lay out A little pissed since i have everthing together and running Silver lining though is that the shaft play on the HX40 is allot tighter than the 35 besides being a higher number are there any benifits or dissadvatages between these 2 turbos?

78zstyle Posted May 4, 2013 Share Posted May 4, 2013 I've READ that the HX series is better than the HY. Something about more boost, faster spool and lower EGT. Quote Link to comment Share on other sites More sharing options...
letitsnow Posted May 4, 2013 Share Posted May 4, 2013 There's an HX35, an HY35, and an HX40. The HY35 is a smaller than the HX35 by a small amount, and the HX40 is a fair bit bigger than the HX35. The HX40 should not be spooling faster than an HY or HX35. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted May 5, 2013 Share Posted May 5, 2013 Might of gotten mixed up, you are right about the hy35 being smaller. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted May 5, 2013 Author Share Posted May 5, 2013 both my hx35W and HX40c look about the same size.. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted May 9, 2013 Author Share Posted May 9, 2013 I found an adaptor that fits perfectly!! Holset vband to 3" vband no machining at all outside diameter is 4.4" 30 bucks BD diesel PN 1452520 http://dieselperformance.shptron.com/ now i just need a 3" vband clamp and i can connect everything back up and tune Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted June 4, 2013 Author Share Posted June 4, 2013 well, good news and bad news Good news is i got my exhaust complete and my car running with the new turbo. bad news is it makes 20 psi, maybe more because i let off the throttle. I have my waste gate hooked up to the top of the waste gate, its a tail external I have a 7lbs spring in it but its way beyond 7 psi... any tips? here are some pics Quote Link to comment Share on other sites More sharing options...
Xnke Posted June 4, 2013 Share Posted June 4, 2013 That doesn't look right. Your boost line should be running UNDER the piston, so that boost pressure helps lift the puck. I think the way you've got it hooked up now, boost pressure is holding the wastegate shut. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted June 4, 2013 Author Share Posted June 4, 2013 Just found that as well thanks for the quick reply, just took it for a drive and she makes about 8 psi and the screamer pipe sound pretty sick! once I figure out my wideband O2 then ill put the 15psi spring in Its funny how i can go from completely gutted too super happy in just mear moments Quote Link to comment Share on other sites More sharing options...
