Ok I'm new and kinda :oops: but have been reading alot on this forum what I really want to know is what upgrade is gonna give me the most power. I have already done the pump mod and the wasye gate. I have about 700$ can. for upgrades and I know the first two things I need are a pyro gauge and a boost gauge. So that will eat up some cash but that is not part of the 700 the motor is a 1989 1.6td and the aplication is in a suzuki samurai. I was hoping for around 115hp if possible so any thing that you can tell me would be cool I heard about the giles pump but cant afford that at this time so I was thinking of a passenger performance cam and bigger injectors to start with. Thanx for the help James Morrison :D

I would for sure get the EGT and Boost on there, if you've already turned up the pump. From what I've read, 120hp is possible with just boost and pump mods, in the 1.6td, but you've got to whatch that EGT.
-
y aI now that much what I was more intrested in was cams, injectors and things of the sort. I just think it would be nice if it didn't idle so high that and well 120hp would be nice but more will always help. Curious what do these things rev to and what type of tach should I get also who here has anything like propane, water methenol or other catalyst injection and hows it working ( I'd say NOS but well not thinkin I need it) Thanx for the help deepmud always a pleaser.

giles pump. $700us is almost enough i think.
-
Get your gauges in first,and get a baseline before you go nuts with the mods.Yu will also have an idea now of what kind of boost your running and what you EGT's are.You may not be running as much boost as you think you are,and there is room for more.
Do the injectors first.It will give you more power due to the bigger nozzles,and yours are probably dirty and worn anyways.
Intercooler will help,and keep EGT's down.
Play with your pump more.Govenor mods and more fuel may be possible.
Once you have done all that,it's time for a Giles modded pump.I wouldn't do a pump until you have the above stuff done first.

Ok well I've already had a pryo and boost gauge on the motor and with the help of my friend that apprentised in germany durring the second world war that work on the first vw's made. With that said what about Passenger Performance cams has any one tried them are they any good. I was gonna go through Smog and get some injectors and then once this thing is off the bench tweak the boost and fuel more I'm already at 15psi for boost and thats by 2700rpm. What other power upgrades do you guys do. I mean generaly I build ricers not diesels so you cam it turbo it then give it the drugs and hold on. Now I wanna build a daily driver but has anuf umph to make my 37 inch tires spin in the goo. Thanx again James Morrison

120 hp is going to move that rig pretty well.
I didn't notice the "james morrison" first time :D
Do you have this thing on the road yet? That Sammy trans is going to have a hard time living with the kind of torque you are thinking of. A 100 hp diesel pushes the trans twice as hard as a 100 hp gasser - I was hurting the Suzuki transmission with a 100-ish hp 1.9td.
You could look at making a boost-controlled VNT turbo work. Check ebay for cheap deals on them.

Actually I'm gonna go with a turbo yota tranny/transfercase cuase of that. Other then that man this is a damn pricy job so far I'm in 4 grand and still compilling parts. So it might be ready by this coming december ( I hope) right now I wanna know that I'll be able to do freeway speeds so I can take it to mexico and moab. Right now I'm waiting on the bender so I figured I would get the engine up to snuff and hope for the best. So is what I am looking for gonna be possible or am I over my head or is doing the pump and turbo mods gonna do it. And if so what happens if I add a cam and injectorsand free flow exhaust and well any thing else the gurus might say that I can fit on my budget which may soon double ( just found out I'm going back to work ) Thanx once again James Morrison :twisted:

i built a water injection setup for 1$ and some goodies laying around,like a vw washer bottle,and an old carb jet,use some imagination,,,the $1 was for the washer fluid,i put the jet in the intake pipe where the bov dumps into,,,glued/safetywired a jet in a piece of rubber vw injector return line,stuck it in middle of intake stream,before turbo,after filter,ya know?,,,im in the wrong forum,but ihave a mechinacal tdi,i dont have a 1/4 time for you,but i know my trap speed is about 100,and i get over 50 mpg,i found out on a recent trip,try to get a ricer to do that,i let the water in the turbo inlet,id see at least 100f deg drop,and some power too,i just used blue washer fluid,igotta hook it up on the tdi,,,,,tweak the fuel on the pump,block the bov,crank the boost,itll do lo16's easy,maybe hi 15's,,,,,any idea what an et would be with a trap speed between 95-100??my old jetta td did a 15.79,that was stock pump,no intercooler either,,,,,,if i had the big pump,and clutch that woulda hooked up,it was toast,id maybe get mid,lo 15s,15.3 or so maybe,,,lotsa spinnin too yea dude vws arent cheap,but they last alot longer than rice,,and take some serious abuse,,ive got almost 5k in my tdi setup,and thats not even the car,but i figure itll last me 4 or 5 years,even as a hardcore daily driver

Think about saving up for a giles-modded pump, if you want, but just running free-flowing exaust should have you fat and happy with 4.88s and 37-42's. The gearing with 31's and stock Sammy gears (5.sumthin' :1 ) is too low for 65 mph - shoot for 2750 for a fast cruise speed. That's enough rpm to build good boost and power without needlessly revving it out. You know, for comparison, look for what "good" gearing is with the 1.6td equipped Vanagons - they have to push a barn-door thru the air, just like you will with the lifted Samurai - don't go for any more rpm than they use.
-
Sorry to interrupt, but..
From what I've read, 120hp is possible with just boost and pump mods, in the 1.6td
You mean, you take a stock 1.6TD and only by tuning the injection and turbo you get 120-ish hp?? With no IC?!
-
Hey great input and deep mud I ran it through the rpm calc. and figure 5.29s that will give me about 60mph at 2880rpm in fourth. Other then that I still want as much power as possible with what I have so with the boost and fuel up I hope for close to 100hp then add a cam for quicker spooling and bigger injectors for more fuel then at that point I gotta find more power. So I was reading on compound turbos and well that got me droolin and if I get that far then hell theres always nitrous so that will have to do. Though the fact that I will like stated before be driving a shoe box on wheels down the road trying to keep up with traffic so as much horse power as possible is needed I hope all u gurus can help and if ya all need a guinee pig for new stuff email me. Thanx again James Morrison
-
no - it would need an intercooler - I stand corrected. :lol: I'd want an intercooler for sure to go above 12 psi or so. At that point the heat of the compressed air starts to be a bit of a problem, and intercooling really shines.

Hmmm - I need to try some of that - I was concerned about damaging the turbo with water/methanol, however. I have sold my 1.9td and have a 1.9TDI coming in, with a hybrid mechanical pump to mess with. 4.88 gears and 39.5 boggers :D
And a big ol' intercooler :D
-
I found a link for this think I 'm gonna try it though sence it has alchol in it I advise using it post turbo though thats just me heres the link http://www.gnttype.org/techarea/fuelsystem/alkyrecipe.html hope this can help James Morrison
-
ran it for a year like that ,,turbo wheel looked ok,,,no erosion,now i wasnt aimed right at the wheel,,i used a little elbow,that the jet was screwed into,,(the aprox jet hole was about .030-.040 inch) so it was sorta centered in the air stream of the inlet pipe,and i used a capplug witha hole in it topass the hose thru the center,and put that cap plug inthe hole of the stock inlet pipe,where the blow off valve would normally be dumped into,,i was backwoods,i bet some better fittings could be used for sure,i had mine on a shifter button,would hit it wheninailed it,most of the time,,,goin up hills on long trips,if i was pullin like 8 psi to keep steady speed,and ihit it,,icould get out of the throttle,a little,like 5-6 psi,to hold speed,thats tellin me its workin :D
-
How many of you guys are running NOS or Cryo on your rigs figuring its a diesel nos is legal to a certain degree and well want cold air use a cryo. As well as I just picked up an intercooler thats 7x20x2" is this gonna be big anuf for cooling the air anuf. Other then that I was thinking of a nos or propane injection system with a water methanol injection to keep detonation in check any one try this yet. Thanx agian James Morrison
-
any way you look at it, liquid propane could have the same properties as NOS if used correctly. Going from liquid state to gaseous state removes a LOT of heat! (just think about your a/c) less heat means you can put in more fuel :D but the fact that propane burns hot doesn't help much, and can lead to detonation with our high compression engines.
-
no - it would need an intercooler - I stand corrected. :lol: I'd want an intercooler for sure to go above 12 psi or so. At that point the heat of the compressed air starts to be a bit of a problem, and intercooling really shines.
Ha! :lol:
Still, what power do you think it would be possible with no IC, only hardware tuning? 100hp?!
-
with a goog pump mod(governor and advance) and more pressure i think 100hp is possible. :wink:
-
I read in a post way back in the depths of this board talking about natural gas being used instead of propane has anyone tried this with any good results. Other then that gotta see if I can stuff this bloody intercooler in somwhere that is out of harms way and hopfully not kill it and then see about getting anuf cash for a giles pump. What other performance upgrades are there out there that have not been pointed out in this post yet or have we cover most everything. Thanx for all the help again :D James Morrison
-
heh,maybe im crazy,,but y not use the propane as a cryo setup??yea iknow ,,boom,,,,,,,,,,,nos (naws,thanks f+f,sheesh,losers)would be "gentler" than propane,,being the nos is basically oxygen to a diesel,,,,,,,on the propane cryo,,it would be cheaper than co2 wouldnt it?????figure out a way to get it away from lots of heat,,,,,maybe thats a little nuts,,,,idunno
-
maybe for drag racing you could use the propane to 'freeze' the intake charge air? Would need an evaporator, and a ducting system to route boosted air through the evaporator, and some hoses leading the propane through the evaporator. Of course it would be a waste of perfectly flammable propane! Unless of course the evaporator was connected to the intake side to re-circulate the propane into the engine... :twisted:
-
ok lets scrap the propane/cryo idea some how I see myself getting hurt with that idea. Other then that what else is there has any one ( 935racer) had any thing nice to say about cams any power to speak of. Thanx for your input James Morrison
-
not tooting my own horn,,but think about how good my watr injection setup atomizes the washer fluid,,no droplets here,,i thought it would be like spraying water ona fan,and slow it down,,but idont hear any difference,,it doesnt hit the wheel directly anyways
-
Ok I'll have to try this though I thought injecting it through a NOS fumagator nozzle after the inter cooler would be better IMO cause then ya dont have to worry bout that stuff sitting in the ic and hurting it. And does any one know if washer fluid hurts silicone cause if I spend the extra buck I dont want to kill it that quick. Thanx for the input James Morrison
-
ive seen it leave funny looking corrosion onbrass,,ie,jets,but hose shouldnt be a problem,,i didnt let it rip till iwas around 3k revs anyways
