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

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

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..

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

And a big ol' intercooler
