Turbo upgrade question

[towner]

My friend just put a 66/14 on his 12 valve and he has a hx35/40 he took off. Does anyone think that will be too much turbo for my 93 with POD's, gov spring and turned up pump? I have a hy35 off a 2002 and love the way it runs on the bottom. I have to work real hard to get the EGT's above 1300 right now.



Any input would be greatly appreciated

No it wouldn't be too much. I have a sp66-14 with EDM's, but did have POD's with it. You have the hy35 now? What size turbine housing? That 35/40 would do good with a 16 housing.

9 housing I can get allot of boost quick but would like to see some more top end

how much boost are you getting?

if you have to work hard to get it above 1300, I wouldn't do it... that hybrid is going to spool a lot slower than your HY

I have the Hy wastegated @ 35psi... . the engine is in a 59 Apache Suburban and doesn't wiegh too much 5800 lbs after swap couple years ago... . I'm not saying its the fastest thing around but my buddies 97 12v std is finally catching up to it after allot of mods. when I pull (not very often) it will get up to temps pretty quick. I think I'll bolt it on early next week just to see how it works since it'll be a direct bolt on

Talk about a big smile on my face... put the HX35/40 on today... . it will spin the tires(both) anytime you want to in second... will keep it going in third and in forth I think I found the limits of the stock Dodge clutch... . I need to find bigger hills to get my EGT's up... do you know of anyone else with a cummins in a lighter rig? even with the Gov springs as one of my friends said its like driving a rally car. whats next. . even bigger injectors? BTW the fuel screw is now bottomed out but I have to shift so quick that the EGT's never get above 1200 with boost getting to 35 ..... wish my speedo was more accurate we estimated a 0-60 in 7 sec... .

D250's weigh in ~5600-5800lbs. My W250 with 240lbs of me in it, weighs in at 5850lbs or so.



What's next? How much do you want? How far do you want to go?

After a few days of Driving I really like the larger turbo. the old HY boost came in so quick and flattened out, used to run 12-15 psi at 55 now its about 5 psi. The topend power is great I had to take a side trip so I could run up Donner Summit. I've either have to regear or get larger tires. The highest EGT I could make was 1200 @35psi going up the summit.

That's a really cool rig and a very uncommon swap, i've always liked driving something different than the mainstream.
