Engine/Transmission (1998.5 - 2002) HE351ve on a P-pumped 24v?

[Mokerz]

Has anyone tried this? A he351ve on a p-pumped 24v? I have a 00' 913p-pumped 24v 5spd. It has a helix 2 cam, 90#v springs, stainless orings, arp studs, sb DD clutch, 10 plate, 4k gsk, etc etc... I set the motor up to handle much more than what I throw at it. It's only set at 350rwhp/800rw/ftlbs @ aprox 2100rpm. Anyway, I use it as my daily driver and to tow and just blew up my hx35w, which when I built the truck 3-1/2yrs ago was planning on putting in a sps 62 or 64, or twins, like I did on my 97 12v. (different mods, much nastier) But I got busy with the house and work and my ex, knowing the HX35 was on borrowed time with the mods. I kinda like the thought of a vgt off of a 6. 7cr, lites fast and can handle more air and fuel. I am going to try this. I'm sure it will take some tuning. Also, does anyone have a stand alone controler for the VGT? I haven't been around in a while. So if anyone has any input or thoughts that can help me speed this project along I would greatly appreciate it. Thanks!

i did a he351ce conversion. it took me three days. i think the next one i could do in half that time. you will have to fabricate the piping on the spot. there is a stand alone controller for the ve but i have never seen it. i would look hard at the pix of one to see what may get in the way. on the ce you have to rotate the compressor housing. i would think the same could be done on the ve.

how are you controling the vanes in the turbo without a stand alone controler? Do you have pics? Also, how did you like the swap, how is spoolup etc. I have been told Fleece makes the controler, but didn't see it on the website, I will call them monday. Apparently you can keep the exhaust brake function with it too. Oh, and thanks for the information, it's appreciated!

 

[CKelley1]

the he351c does not have the variable vanes like the he351v. i have also heard fleece has a controller, while you have them on the phone ask them if it will fit. pm me with your email address and i will send pix of the 351c install and where to get tubing. i have not learned how to use picture bucket.

 

[CKelley1]

the spool up was super. it was a very good mod. i paid $450 for the he351c and about $100 for miscellaneous parts and tubing. do not forget you have to change the exhaust springs to 60 lb

 

[Mokerz]

why do you have to change to a 60# exh spring? I have 90#'s on intake and exhaust. I think the 24v came with a 60# the 12v had a 30#. Anyway I need to run the 90# due to the big cam. I kinda figure you thought I had something lighter than that, but wanted to make sure I wasn't missing something. I appreciate the input!

The only problem you will have with this mod is that the flange is somewhere between a T-3 and T-4. Look around on eBay for an adaptor of some sort and these turbos go for less than $300. 00 shipped just about every day. Another thing is you need a 3rd gen downpipe to use the cast elbow that comes on most of these. If you don't want to try that route, the regular old HX-40 4" downpipe fits like a glove when you remove the elbow

I tried this mod on my 92 using a wastegate controller to slide the vanes and it worked great! I just got frustrated with not having time or cash to do springs to use the EB and scrapped the thing for a HE351CW out of an 07 that I got for free.

I found this video about a year ago and been kicking myself ever since!!

BTW... Talk to Fleece Performance about the standalone controller and tell em exactly what you have. From the vids they have posted now, I say they have got this thing licked!!!

After finding the last 2 vids while researching this for you, I think I'm gonna try this thing again Oo.

i did not read your question very well. a 97 does not have 24 valves and comes with stock 30 lb springs. you are ok with the 90's. let us know what fleece says. i might try a ve on the next one

 

[cerberusiam]

the he351c does not have the variable vanes like the he351v.

The holesets don't have varible vanes, thats the Garret turbo version of the VGT. The Holeset uses a sliding collar that limits the exhaust flow on the turbine wheel to control spool.



The Fleece controller will give you full control at a price, or, you can build a leve ron the collar control and uses a WG acutator to control min\max sizes. It is a very cost effective way to get a good turbo onto these older engines. They are quite capable of building 50 psi of boost if you set the housing size down around 10cm.



We are running them on 1st gens and they work great.

Read the 1st post!!! He has the dream truck of all trucks and wants to make it better.

 

[CKelley1]

i agree mikey, i had to read it three times before it finally sank in. cerberusiam you are correct on the sliding collar on the he351vgt i used the wrong term of what the controller controls. did you have any clearance problems and how did you determine linkage parts

 

[Mokerz]

ok, got the turbo (he351vgt $200 ebay special), now to figure out how to control it. Would a fleece controler work on a p-pumped 24v manual with all the sensor and the computer still hooked up? The only sensor that is not currently doing much is the APS (aka TPS), it is just plugged in and zip tied out of the way, it doesn't actually know the position of the accellerator pedal. Or will I have to devise some means of controling it mechanically using boost and or drive pressure. I would really like to have the exh brake function and be able to open the vanes up on the highway for optimum fuel economy. Obviously the electric controler is the ideal way to go for fine tuning etc. Any thoughts, ideas, answers? I appreciate the input! #ad



Also, I have heard from some that it is ok to move the position (clock) the turbo exh and inlet to suit my app. I have heard from others that it is not. It has been my exp running a shop that works on class 8 trucks that it doesn't matter and it makes sense that it wouldn't. However we have no exp putting this turbo on a different application. So, what is the correct answer for this particular turbo? Thanks!

also, I have noticed a lot of people not plumbing in coolant to the turbo... Is the coolant just for the electronics? If I go mechanical is there any significant advantage to running coolant through this thing?

 

[Mikey-KE7LBB]

Turbo can be clocked to whatever position you wish. There are pins to align it for the correct position on a 6. 7 that need to be removed. The coolant lines are mainly to keep the electronics cool and also keep the lube oil from coking on the bearing during a regen when the EGT's can be 1500ish for 20 min or more.



The Fleece controller works off of a MAP sensor to regulate boost and there is some info on that on their website. You should give Brayden a call and see exactly what you need since the controller was engineered to work with the VP and CR engines.



Also it is wise to have both boost and backpressure gauges to allow you to fine tune it without grenading your head gasket or building too much heat from excessive backpressure.

Thanks! I appreciate the input!

i have been watching this thread, a couple questions. What kind of job does the he351v do for lowering EGTs? i have 2001 H. O. 6 speed with 120 hp Edge competition box and if these turbo do so good where are they coming from. One guy on ebay has 10 of them for sale.

 

[cerberusiam]

Take-offs form the 6. 7's is the source. People are adding bigger\better turbos for powered up mods.



Yes, they will make an impact on your EGT's, significant impact.
