Turbo project

T04B

The trim is a V2 on my t04b with a 1.15 hot house.

I have no idea how to read this.

I have been told that it will spool around 2-3K, but have been told a million different things. I still need to get my pistons, and then my stroker will be ready to put back together (heads on block with cam and crank, tons of other crap still needed) but I am going to run it as it is. If it spools up late, then I will get a smaller HH.

I downloaded DeskTop Dyno and I really like it. I played with a bunch of setting and turbos that I could probably get and learned alot. This is what I got with 6lbs of boost and a 40% IC. (I'm guessing I could hit these numbers with my injection system)

This is with the turbo I snagged from a Le Beron, but I don't think I am going to use it because it has excesive play. But it was only $12. From the datasheet it looks like it spooled up at around 2500 and kept the boost up thruogh my 4800rpm rev limiter. My HP actually peaks around 5500 but my cam choice limits my rev range and I would risk valvetrain damage it I go that high.

Out of curiousity and boardom I plugged your turbo into it and came up with these numbers.

I based it on an AP 4.6L stroker, because I didn't know specifics, but it looks promising. That is with 6#'s of boost.

I am doing a "my own" recipet to do the stroker. 1990 YJ 258 crank 4 CW with the short snout. 707 forged rods, Vonilai (sp?) pistons @ .060 over w/33 CC dish, .043 mopar head gasket and shaving the block a bit. I will also increass the CC in the heads by 3-4 and not shave it. Using a Crane 753901 cam and matching lifters, spring and retainers. 2.02 SS intake and 1.56 SS exhaust (ordered 1.60 but didn't get um) port matched (the best I could) the heads to the gasket (which was larger than the intake and exhoust ports) Using a 68 mm TB and machined the intake out to 69mm, a TB spacer machined to 69 mm to match, and a set of roller rockers. Have gibson headers and will do a nice a$$ (whatever it will be) 2.5" exhaust with high flow cat and mufler. Stock quench is .65, and I was told to run it at ~.045, but will shot for a .50-.55 and run an alci/water injecton system straight into the top of TB so that it does not travle through the turbo. I was thinking of putting the turbo on the headers and run it up (about 4 city blocks of room, unlike bears set up) or putting it in the stock air box location and running a snorkle (just to cool the air down some), 2 or 3 bar map instead of an adjustable one. If I can get close to 450-500 in HP/TQ range, that will be nice (~1200 rpm). I have a SM465 that I thought about using, but with that kind of #'s, I would need to carry a spare jeep for parts on the trail. But I doubt that the 350 HP/TQ rating on the AW-4 can handle it. level 10 tells me that they have a rebuild kit for the AW-4 that can handle 750 HP/TQ. Once I get the pistons, I can put motor together and slap it in, then I can work on the parts that attach to the motor later, water pump, injectors, turbo, things like that. Oh and oil pump.

With 8-10 lbs of boost. :rolleyes:

If I had the skills, I would build new intake with 3 runners to one 68 mm TB and the other 3 to an other 68 TB and have just one of the TPS's hooked up and have one connected to other to balance them. But don't know if a single turbo will handle the split, and don't want duals.
 
The closer you hold the quench, the less likely you are to get detonation...on the exhaust manifold...shorter tubes the better...you don't need big tubes either, the pressure drop will be across the turbo...wrap the exhaust with insulation including the hot side housing on the turbo..not only will this help with underhood temperature, it will help with power output. another way to go is have the exhaustmanifold and turbo housing ceramic coated..doesn't insulate as well as the wrap but nothing will rust...and deburr everything in the combustion chamber to eliminate hot spots..if you have the motorcraft based ignition the wire that goes from the ignition box to the starter solenoid when activated will retard the ignition some...you could rig a hobbs switch to activate it if it offers enough retard for your purpose..
 
Its cool to find people working on turbo xjs mine will be finished for the most part this weekend
as far as the used parts a concerned I tried the used route with no luck my used turbos turbine shaft broke I decided to go with new parts I have pics but I dont know how to load them if you are interseted email me
here is a list of parts installed
switzer t04b
tial 32mm wastegate
24lbhr injectors
mits eclipe blow off valve

I am planning on doing a turbo for my 4.6 in a couple of months. So far, the only turbos I have come across at the pull-and-save are for smaller engines with displacement under 2.5L. The goals of my project are to create a set up with minimal lag, be able to run 2-5lbs of boost, and fit completely under the hood. I would like to have the manifold come strait out with the turbo next to the intake manifold, it looks like there is enough room. I would like to begin building the manifold soon, is there any special considerations when building one, do the runners need to be equall lengths? I will be making it out of my old renix manifold. Is it a good idea to go with a smaller turbo? It will spool quickley and I don't think 5lbs of boost is past there limits? All my parts will be from the pull-and-save, turbos are $16 IC's are $16, blow off vales and wastegates are $8. With my 24# injectors, adjustable MAP, and relocated IAT, the RENIX system should be able to adapt to the boost conditions and I should be able to get a working turbo system for under $150. Any input would be appreciated.

Here are some pictures of my set up in the install stages with any luck they will come up
the insulation had to be removed to much heat was being retained in the manifold. my jeep is up and running and the turbo seems to be working great no problems I think that I may have to upgrade my fuel pump and install a rising rate fuel regulator but so far so good

Looks awesome man, good to see such a clean install, can you give me breakdown of what parts to get and from which vehicle, i can go and get them, can you also write an install article, i am asking a lot of you but would really appreciate if you could help me out.I would really like to copy you and the fact that yours is a Renix is even better.
 
This is cool stuff you guys are talking about here.

On my other car I'm running a supercharger with water/methanol injection. At 10psi we're seeing intake temperatures go over 200 degrees. With the injection, the temperature consistently goes to about 110-115. I had the best luck with 50/50 mix of methanol and water. The methanol soaks up the heat real well, and the water, it does everything you guys talked about. We're actually advancing timing over stock with this injection setup.

I would think fuel pump and a rising rate FPR will be a must.

I will see what I can do it will probably take me a few days to get it all put togather.:wave1:

Oh yes, too good to be true. I just managed to find myself in possesion of two T04Bs (very much used unfortunatly...rebuild time) this last weekend! (Hooray for grandfathers with shops full of junk they don't use anymore!)

I've been planning on TCing my '97 XJ pretty much since I purchased it (about a year ago now). Any extra info you can provide on your install will be greatly helpful!

For starters, how much boost are you running? And what compressor/turbine ratios?

I am running 7 psi my compressor side is a .60 and the turbine is a .96 p trim to4b
I have not had time to put togather any good pics.
As you have seen in the pics I used a stock manifold cutting off all of the tubes and installing a single collector. The collector is 2.25 in with a three in section dropping down into the turbo flange, the waste gate is feed by a 1.5 in pipe. the wastegate dumps into the exaust pipe after the turbo. I used a 3 in mandrell bent pipe to make the drop from the down pipe flange into the exaust. The turbo starts to wind up around 1900 rpm, full spool around 2500 rpm. As I stated before I need to get more fuel but even with that problem I am really pleased with the improvement in HP and drivability. I will work on getting some more pics out soon :looney:

Thanks for alerting me to this...Unfortunatly I am currently broke, so for now, no rebuild kit. I am also nearly sure that the main thing which is going to need replacing is *cringe* the wheel itself...the blades on both compressor and turbine side are in pretty bad shape...In that case I'll probably just end up waiting for a good deal on a new T04B to show up on eBay.

Speaking of good deals - there may be others looking at this thred that will find this useful:

Genuine Garrett T04B .60/.96 p-trim..."Buy it now" $350...From what mtbkr is claming about the RPMs he is spooling at, this turbo seems like the perfect choice to get the job done...Full boost at 2500RPM is close to nirvana on the 4.0L in my opinion :) I just can't wait to feel it for myself!

I installed a rising rate regulator today set it up to run 40psi with no input from the manifold
this has it running 35psi under vac and aprox 47 psi under full boost (7psi boost) the hesitation under full throttle is gone and it is running great
:loveu:

That's awesome! Now where are the pics!??!! :)

I can't wait to get mine started...just pulled apart the turbos I've got today, looks like I should be able to get one of them rebuilt and running good, as it has minimal shaft play. The other one is pretty much shot though :( But I'll polish it up and it sure will look good as living room decor :D

How much HP increase do you think you've got? Any plans on getting it dyno'd? Taking it to a track and getting a 1/4 mile time??? These are the true tests :D
 
Having all the hot side parts ceramic coated will help with the heat problem...side benefits are increased efficiency since it is the heat energy that actually drives the process and the coating will keep parts from rusting.
Unfortunately I have no useable input on setup or tuning...all my turbo info is for carbed setups...hook up with some ricer tuners for input, those guys are on the leading edge of turbo technology.
