Engine/Transmission (1994 - 1998) spool up diff.

[RBratby]

what i would like to know is how much of a difference is there between a 16 housing and an 18. 5 on spool up? will the 18. 5 be ok with the set up i have right now? this is only for a short while so i can save some money to get a bigger turbo. i can get to 1300*+ pretty fast. i would also like to know if this will help my egts from getting hot so fast? any advice would be greatly appreciated. thanks richard

im not sure but i have not heard of to many people running 18. 5 housings on our trucks unless they have hx 40s. not to say they are not out there though

I would go with the 16 and stay away from the 18. 5 as even with all that fuel it will take you a century to get that spooled with that large of a housing. I haven't really heard of anyone running that large of a turbine. Most people who have your set-up, the HX-40/16 is the way to go. And even after that most just go to twins if they are running any more fuel than what the 370s can put out.

 

[RBratby]

the reason for asking this question is because i can get a 18. 5 housing for less than $50. this will not be on for to long. it will only be on for about 2-3 months. im trying to save up for an hx40 or an htb2. i just need a housing a little more free flowing. thanks richard

Yes you will be fine with the 18. 5 the egts will rise a little slower but it will still get hot on a hard pull. Spool Up will be a little slower too but not that bad and you will loose some boost and have more smoke.

 

[RBratby]

im not to worried about the smoke or the boost press. right now with the things i have done to the truck i can get about 36-38 psi so i guess i can lose a few pounds and be right back in the range of a hx35. the reason for the housing is so egts will come up a little slower. my egt gauge will almost move as fast as my boost gauge will when i go into lockup pushing it pretty good.

Remember too if you go to a non w/g housing your exhaust will be too short.

the housing im getting came off a 93 cummins. im not sue if they were w/g or not. can someone tell me if they were or not?

 

[MHoover]

i don't think they had wastegates until 94

 

[Bob4x4]

That would be no w/g

I would slide the plate back & save your $50. 00 toward the 40 turbo which is what you need anyways then slide the plate fowards again.

Do you still have the cat on?

I would leave the plate forward and use your right foot to control EGT's and start saving for a turbo.
