hi nogs, from australia

1998 holden rodeo tray.

2.8l turbo diesel 4jb1t, 5s, 4x4, LSD

stock turbo is an ihi rhf5 (ultra tiny, i get full pressure (9psi lol) at 1300rpm in 4th....)  Jew

mods:
cdm cooler, 2.5" dp exhaust and chargepipes, in cabin mbc, boost pyro drive pressure gauges, removed rear canopy and the a/c, moved battery and coolant tank, 30 x 9" bfg a/ts, homemade catchcan,

7 rattle cans of flat black paint
50,000 zip ties




before shot





stock motor 



fluxcore 2.5" dp, cast to mild 



you like?
all junkyard exhaust, 2 straight thru mufflers from diesel ford van, reused hangers from old exhaust



when tapping ex mani for drive pressure gauge and pyro, found i couldnt turn the tap wrench.....



until i grabbed a 1/4" extension, perfect fit!





during mock up



cdm cooler and homemade piping, flat black, 2.5" mild, all fluxcore welded. airbox is from a junkyard daihatsu charade hatchback lol



engine bay side, cut 4" hole in bottom of airbox for flow...


ve pump, looking back from radiator



cooler mount bracket visible behind number plate


it was an epically long project, glad this part is done.

next up: bigger turbo tdo4l from wrx, turn up the pump (bosch ve pump by zexel japan), 20psi, steel front bumper, more pics

any q's etc welcome.

I like this. ;D

Are you posting any ripper vids or off road vids when you get the bigger turbo on that?

[dvst8r]

Looks like there is lots of room for twins. Do you know what the plunger size is in the VE?

[crxvtec91]

That mani looks super restrictive. I like :yes:

[ochoa]

stealth sleeper black FTW

i havent even touched the pump yet. my plan is to crank the boost in the stock 38/52mm turbo to a bit less than choke point, and a bit more mid range and top end fuel.

boost currently 15psi, drive 21 psi max
 
yes, there is heaps of room in there, if i do twins it could be garrett t04 over 42/52mm mitsu td04l. perhaps. any suggestions.

also looking at a he341ve as a single but worried about comp surge....

cheers

[dvst8r]

Sounds like you are already at the max for the stock turbo. I would be wiling to be with any more boost just comes a ton more drive, and you aren't far off of 1:2 already.

If you are going to do twins with the td04l, I would look at the HE351 60mm, or an HX-40, as the HE351cw might be a touch restrictive on the exhaust side as a primary. HE351VE would work, but you would have to either get the vanes to work (something like aero did) or just set them at a fixed position.

I wonder if you pump has gov springs like a vw, or like a cummins. Either way that would be one of the first things I would do, is mod the gov for more rpm, add some fuel, bump the timing an 1/8" or so, and evaluate from there.

thanks dvst8r.
time for a street tune today, more fuel should help. ill read up about the timing advance.
im not keen to turn more rpms, it happily revs to over 4k stock, just zero tq above 3400 - drive pressure climbs fast. 4400 rev limit stock.

would a hx35 with 14cm hsg work well for a primary? might have access to one...

 

[brine04]

at what rpm does it start to defuel?

[SloS13]

Great to see anything out of the norm on here.  Wish the US got small diesel pickups

[rprznt]

Do you know what the plunger size is in the VE?

at what rpm does it start to defuel?

4 cyl

11mm plunger, and as per pump serial number, "governer controlled rpm number" is 1900rpm. i do not know what this means.

has mechanical governer

pump s/n: NP-VE 4/11F1900LNP1685

any clues about the governer number?

[dvst8r]

HX-35 14cm if it is cheap will work just fine, you can always do a 60mm compressor wheel upgrade if it is limiting you.

1900rpm is pump speed so x 2 for motor speed 3800rpm is where is should start to defuel. I would mod the gov springs so you can at least pull full fuel to 5K. Heck I run stock cummins to 4K, and stock vw td's to 6K.

Adjusting the timing should be nothing more then loosening the front 3 bolts, and then one rear bolt, and pushing it the whole pump towards the head. Might need a ratchet strap, as some times they are sticky.

Back the high rpm screw right out and throw it away, and as you add fuel pull the low rpm screw out to bring the idle back down. Adjust the throttle cable and linkage for full travel.

Pop the top off the ip 4 flat head screws, and index the pin for max depth, shave the nylon washer so that it travels all the way to the deepest point. When you get it apart you will see what I mean, as there will be a rub mark on the pin, use that as a guide for which way to turn it. **Should be so that max depth is towards the Rad** but I have never worked on that particular setup so it may vary.

Dave (Passenger) has made 200whp on a 9mm 4cyl pump. With the 11mm pump maxed out you should be close to 400hp worth of fuel. Stock 12mm VE's on 1st gen cummins will move nearly 500hp of fuel maxed out

If it doesn't already have one, add a lift pump now, set it so the pump sees 15psi or so. This is very important.

If you really want to make some power, I would look at an HY35 with an external gate over something in the 64mm range. The TD04l over an HX-35-14 should be good for 300hp at reasonable egt's and 350hp+ if you ignore the egt gauge. Or you could aways spray it at that point.

in reality i will only ever rev it to 3700ish anyway, and prob not regularly.

i saw a youtube video and a tech writeup, timing bump, turning fuel cone pin, and star wheel look easy to change.

diagram was useful



i'll remove the high rpm throttle stop pronto.

can i use an inline efi fuel pump with external reg for a lift pump? seems easy to make.....

junkyard bosch 044 here i come.   

[dvst8r]

Yup, an efi fuel pump with an external reg works great.

[drivin96]

tire jack stands ftw

[rprznt]

tire jack stands ftw

thats damn right, i even have 4x4 wheels for extra height when needed !!

thanks.

 if a lift pump not added and the inj pump turned right up, what are some bad things that may happen? damage to ip's internal vane pump?

[dvst8r]

Outright IP fail, it can damage the camplate, and seize the pump.

[onlyflash944]

love the jack stands.  they won't ever fail or creel out from under you

[Random Hero]

I like! Subscribed!

shit 

ill get right onto it then.

I'm all about diesel, and man i wish we had more small diesel engines around here. Only thing i can get my hands on thats worth a shit is the 4bt/6bt/isb cummins..

[onlyflash944]

i've fooled around with several roosamaster db2 injection pumps, and have never seen one sieze up.  however, it isn't ouside the realm of possibility, i would just say highly unlikely.

the 6.5l canister style lift pumps can be had new for $80ish or you can go to advance and buy the little green (mr. gasket i think) ones for 50.  should be enough for what you are doing, but if it doesn't have a lift pump, then you are asking for trouble later on.  think of how much stress you take off the IP when you have at least a small pressure from the lift pump on the intake side of the IP.  as far as a return, i don't know much about your the isuzu return system, but if there is one after the IP then you shouldn't need a regulator

worthless 4bt?  how many are around you and how much are these worthless setups selling for?  i know people that would give good money for a running 4bt swap

[Random Hero]

um, i speak english, and i said WORTH A SHIT. you can find them all over for 500-800 dollars. I currently have 1

got mine out of a fritto's lays panel truck. easy to find but no one ever posts them up for sale.

725lbs tho so heavy.

[onlyflash944]

jsut about anything is fixable.  one of my buddies wants one badstyle for his jeep trail rig.  we make biodiesel together in his basement and he has a benz and a 7.3 idi he runs off of grease.  i've looked on craigslist for over a year and never found a fritto's lays truck around this  area, even for sale

How often have you asked them to deliver double or more the fuel that they did stock? I have personally burned through 2 VW bosch VE's and 1 cummins bosch VE. They use the excess fuel for cooling and lubricating the ip, and have been witness to several others. My stock vw tdi doesn't come with a lift pump, but I put one on anyway, it is cheap insurance, and it made extra power as the timing piston didn't have to wait for the case pressure to build with rpm's.

Speaking of the timing piston, there is another mod if you get to the point of really wanting to take the pump to the max.

I kinda doubt given that he is from Australia, or somewhere on the opposite side of the world, that he can just run over to advanced.

I prefer having a decent fuel supply, and regulating it down, vs having a soft fuel supply and worry about a bad tank of diesel, leaving water in my filter, and now instead of having 5psi I have 2psi, and vacuum at WOT.

good advice, thanks.

i dont understand the red bit...?

as far as a return, i don't know much about your the isuzu return system, but if there is one after the IP then you shouldn't need a regulator

ill go have a look right now. 

[DRQPQUT]

shit looks fun, but we are gonna need some vids ...stat

[rprznt]

vids shall come once setup and tuning is done 

dvst8r: how is that "fuck a wg" twins setup for the 6bt going? -sexy whitey bends 

update, went for a 35km drive down the freeway. level road, unloaded, no wind, 12*c.

at 100kph motor turns 2750rpm, 15psi boost, 21ish psi drive. when i nailed the throttle (5th gear) boost started creeping a few psi, drive pressure rose FAST.

silly little turbo. 

egts never go above 450ish*c unloaded, with stock fuelling and timing.

any opinion on a he351ve vgt?

im afraid of comp surge..... only a 2.8l motor

i can control the vains easily, and id not run a wg, exhaust hsg should be big enough, vain position and topend fuelling would control the boost i think.

ideas??

Sorry let me clarify. So instead of having 5psi at idle, you now have 2psi from the clogged filter, and instead of having positive pressure at WOT you now have vacuum.  VS a higher pressure pump capable of a lot more pressure and volume with an external regulator. Where at idle you have 15psi, WOT you have 15psi, partially clogged filter 15psi ect...

The twins are on hold I stole the primary, to use as a secondary on another set (up coming thread, probably in June or so) Probably will have another twin setup done in between those two as well. Lots on the go these days.

Yup, sounds like the tiny turbo is too tiny.

I think the HE351VE would be a little much as a single, it would probably just light, and you would be out of rev's, or have like a 1000rpm power band. As a primary with that td04l secondary it should work well.
