Increasing Cruisers Performance

[danhr]

I am seeking to dramatically increase my Cruisers performance. Is it simple as increasing the injection volume and boost? Please share opines people.

[eleblanc]

What engine?

dramatically = turbo

[danhr]

I am intrested in 13B-T. It already has a CT26 turbo.

[dreko]

Danhr: Good question.. I'm curious if a 13bt and a good aftermarket turbo'd 3b are very similar in terms of HP

[lshobie]

open up your wallet

Turbo
intercooler
dump pipe
mandrel bent 3 inch exhaust - free flowing muffler
water/meth injection (this is next weeks project)

I have done most of that and I turn the fuel down now for better fuel economy, but when I want more power I turn it up for fun. I'm running 13 pounds boost now.

Have fun!

Thinking of doing a little bit of this: YouTube - Tawau drag race class asap E-tam Dec 2007 diesel Power?

lshobie:

What engine you got there?

Would be nice to see a hombrewed methanol injected cruiser.

How did you increase fuel? Had the pump redone?

[crushers]

turn up the boost
turn up the fuel
add intercooler
larger exhaust 2 1/2" is fine for that little engine
add propane
change the gearing

are you looking for faster off the line or higher top end?
with the 13BT (max rpm is 4100) X 4.11 diff and 30" tire and .85 5th you will achieve a MAX top speed of 168 k/h (104 mph)
change the dif gears to 3.7 and the tires to 33s and your top end is 206 k/h (128 mph)

with Louis's 1HZ he is running 4.3 diff, red line at 4700, 36" tires and .85 5th so his top end could potentially be 227 k/h or 141 mph...
the HZJ40TI/C i just built has the 4700 rpm, 33" tires, 3.7 diff and the .85 o/d so the calculated top end of that truck is 236 k/h or 146 mph

in any of these cases you will be walking for a long long time if you get caught.

also propane injection.... search for some of Crusher's posts on that. He seems very pleased with it, it isn't a very expensive modification (depending on how you do it) and can add a bit of oomph without adding much risk as it should make your motor burn fuel more evenly and perhaps a little cooler egts


edit: ha! looks like Wayne posted while I was posting

Danhr, it has the old pump on it, never been rebuilt. I just turned in the fuel screw. I wil be installing a new pump this summer though - just after I add water/meth, rebuild the gearbox, install front arb locker, install completely new wiring harness. Hmm, I have about 10 million dollars into this truck:(

I'll sell it for 75K though, anyone??

To each is their own, if your diesel will be under 250 HP use propane cools the charge air. For 250 HP and over (say if is like 160 HP stock rating) I the key word I would use water methanol injection it keeps the internals ie: piston, cylinder and head cool. Also, it helps destructive forces like over advanced injector timing, thus keeping your motor lasting much longer.

[danhr]

I have an idea. Homebrew water injection/methanol injection. I am thinking of using a fuel pump (found in petrol saloons), a jet, piping and small reservior under hood. The injection will be made after turbo. Since fuel pump has a flow rate of ~70GPH and high PSI, a fine jet would spray mist of methanol.

I have worked with fuel pumps in past so I know it will work well.. Wonder if anyone has tried this before.

Price? Well, last time I bought a single fuel pump for USD 10/-. The jet would cost another 10/-, say piping and reservior 10/-. So cost won't go above USD40/-.

A V8 350 chev! thats what i'm doing! AU$4750! just put it in and the way you go!

[crushers]

do a write up, i would be interested in your results..

Bingo! It should be fairly easy for you to calculate the dollars per horse power gains of either adding breathing to the 13B-T or re-motoring.

The cool thing about installing say, a 6.5L is that you won't have all the finicky gadgets and doo dads for power extraction that you would have to add to the 13B-T.

You may consider that installing more cubes is cheaper..... and more reliable.

the cost:benefit equation for going to a 350 vs. performance mods on the 13bt is complicated.

It probably depends on how much "dramatic increase in power" you really want to get.

The advantage to building the 13bt is that you can do things in steps- spending a few hundred here and there vs. dropping a few thousand and a decent amount of time into swapping the motor completely.

Adding an intercooler, for example, doesn't really require much down-time at all. You can gather all the parts, then do the mod in a weekend.

Similar on propane injection or methanol injection.

I guess it also depends on what you find "fun" vs. "work". For me, body work is just work. I hate doing it and put it off till I can't ignore it. Mechanical stuff, on the other hand, I actually enjoy the process, most of the time.

want a chev...then go buy a chev

but that is just my view of chev engines installed into a cruiser...

by the time you sell the cruiser you will have lots of money to buy an old blazer and swap a diesel into it... a bastardized Cruiser is worth shit on the market

and buy the time you are finished with a PROPER chev transplant installed into a cruiser you could invest the funds into the above suggested mods, have better fuel milage, better performance and better resale....

but <see sig line>

Interesing post .. with a bunch of money and custom rods, pistons, rings, along as the other parts posted above you can push a 28 PSI intercooled engine .. that can make pleny of powa .. even in this case would be nice to see if you can reach the 250 HP barrier .. ( wheel HP .. )

[lshobie]

Tapage, I am considering a build like that - never built up an engine and other than OEM parts not sure where I would get those high performance parts. Are they something I'd get from an engine builder locally? How do I spec that stuff out?

I found in Australia Outerlimits .. some ( not really much at all ) info about custom rods, pistons, and related ( piston pin etc ) .. seems there are not much business field to improve the performance on Toyota Turbo diesel engines much more than a intercooler ( watercooled ) and propane / mehtanol options ..

Looks there is a line close to 220 HP ( in a 1HD-T ) at the flywheel that everyones respect .. over this line looks everybody take the swap engine route ..

[crushers]

you have to remember, the front diff on the 90+ Land Cruisers are the small "mini" truck diff, the rear diffs are still the full size BUT even those are breaking under the chev V8 hp and torque.

if you are going for top end then the parts will hold up fine, if you are going for "off-the-line" performance then the engine will be the cheap part of the build.

[canucksafari]

Looks like you will need to swap in a Patrol drive train.

In a Japanese Diesel ( alot of fun but lack ?) IMOP the 13-15B-FT would be nice to power up . They already have the key ingredients ( the 1HZ crowd wont like me) they are Direct Injected and have much lower compression . That is the problem with these engines is that they reach high egt's in no time because they are a LOW BOOST engine.

Unlike the 6BT C. I have' that thing runs at around 30lbs all day actually more like 36lbs . Non intercooled at full power the highest I ever got it was around 900f. I disconnected the turbo once and it went off the scale.

IMOP the 13B-T should handle 20lbs boost . With the IP set right you could be looking at close to 180HP. reliably . I will be looking at turbo's at the end off summer and set something up.

[Tapage]

I only " know " one person that are pushing ( or was ) 20 PSI in a 3B and this is Peter .. actually I believe that the best engine or plataform to push the limits would be a 12H-T .. no clues ..

6 Cilinder + DI engine + Factory Turbo + Adecuate Comp ratio + capable IP + gear driven + NO BEB's know issues + capable turbo + piston oil squirt

Something else . ?
