Topic: 98 Boosted short tacoma (3rz turbo)

[Crunchy Taco]

I don't recall. it's prob not the greatest cause it's a cheap mani. there is some kind of like chrome coating on it as well that may be what's throwing you off.

[Crunchy Taco [OP]]

what's weird is when I ground into parts of the manifold it had like a brass sheen to it. I don't kno if that's nickel in the material or what, kinda weird you'd have to see it up close

[Crunchy Taco [OP]]

you can kind of see the brassy color in these pics. maybe this is part of the nickel/chrome coating I kinda sanded of the flange here

[Crunchy Taco [OP]]

here's some pics of how I have my boost controller hooked up. one of the tubes coming off the controller just blows off to the atmosphere

[Crunchy Taco [OP]]

here's my homemade manifold that's in bad shape. it held up for about a year or more but is starting to crack everywhere. prob cause I don't have it braced up. she's been good for my first turbo mani I built. time to try someone else's prebuilt manifold. if I ever build another one I'll use stainless and really take my time on it.

[Crunchy Taco [OP]]

I installed an adjustable fuel pressure regulator I got from eBay. it seems to work pretty well. I suppose I'm pushing my stock pink injectors to their limit. I really really really need to get bigger injectors.

[Crunchy Taco [OP]]

oh yea, the pictures

[Crunchy Taco [OP]]

I probly already explain this earlier in the thread but there's always the question should I run my maf sensor pre or post turbo. well on my truck with the stock ecu with piggyback controller, post turbo was what worked. when I had it pre turbo my truck died every time it returned to idle. just something I wanted to add for anyone workin bugs out of their 3rz turbo project

been having trouble with my clutch slipping for quite awhile now. the clutch kit is fairly new about a year old but it's a brand from oreilly auto parts so it can't be that great for a boosted truck with big tires. so I bought a ceramic sprung puck clutch with a 1,600 ft lb pressure plate. guna install the new kit this weekend. once all is well with my drivetrain holding up I plan to have my truck dynoed at KO Racing. finally should have some numbers here within a few weeks. my turbo setup is as dialed in as its guna be for awhile so I'm excited to see what it puts to the wheels. I do wana get my new exhaust manifold on as well before the dyno I welded the cracks in my current mani for the time but I'm guna slap my new one on along with a new down pipe and bigger exhaust I've gathered. I think my new exhaust setup manifold and all will wake the truck up quite a bit. stay tuned.

I got mine running!! How much boost you runnin?

[Crunchy Taco [OP]]

good to hear. I'm currently at 8 psi. it's been really strong at that setting. not too little and too much cause I'm still runnin stock head bolts and gasket. hope you got your mega squirt all figured out.

[Nation]

Im at 5psi. Almost got it all worked out. Just need to figure out the IAC and get my idle down and im good. Running the same psi as before with much more power with a good tune. Im gonna step up to 8psi myself. You ever read anything about what the stock bottom end will handle? (Psi)

[Crunchy Taco [OP]]

I read a forum a guy was runnin 14 psi on stock internals and hg and no studs. but I think he was workin on gettin that done. one thing that I did that helps a ton with circulating the motor pressure is this: run your pcv valve like normal from the back of your valve cover to the intake mani but use a good one way valve that can handle boost pressure. then off your front valve cover breather run a hose from there to your pre turbo intake pipe. your turbo spooling hard creates vacuum and pulls pressure from your engine and then as soon as your back in normal non boosted vacuum your pcv valve obvious works like normal. the one way valve helps block boost from goin the opposite way through your rear pcv hose cause I think some pcv valves can't hold back boost pressure. anyway my truck as been pullin a lot harder since I did this. I explained it the best I could. the research is out there.

[Nation]

Ill give it a shot

[Crunchy Taco [OP]]

before I routed the front valve cover breather to the pre turbo intake I had a breather filter on it just like you. I'm sure all is fine with that but having vacuum seems way better, pulling crankcase pressure out, especially if you wana run a catch can in line

finally put my flat pit arm on and notched my frame out for it to clear. I also built a new tierod and drag with 1 ton rod ends but still deciding on either modifying my high steer arm on the pass side to accept the bigger rod ends side by side or to buy the ones from front range Off road that are longer and blank so you can drill your own holes. http://cdn6.bigcommerce.com/s-wmek5/products/260/images/296/DSC_0016_800_main__69715.1416270416.1280.1280.jpg?c=2

got some new shoes on the ol pregnant dog

[Crunchy Taco [OP]]

little update on the truck

[Crunchy Taco [OP]]

I put the new manifold on and 3 1/2 exhaust all the way back. huge improvement it rips hard now. sounds like a boxer motor it's crazy

[Crunchy Taco [OP]]

kinda sucked I was makin my exhaust as badass as I could then I ran out of gas in the middle of the night and had to use flux core cause I needed the truck in the morning. so there's some ugly flux core welds but I guess you can't really see exhaust anyway. I highly recommend 3" or bigger pipe on a boosted engine what an amazing difference.

[Crunchy Taco [OP]]

I have a little advice after experiencing it first hand. build a nice brace for your turbo setup if you want to prevent your nice new turbo header from cracking. odiously the better quality the header the longer it will probably take but I believe a big heavy turbo hangin on a tubular mani especially will eventually crack the out of it. I recently put a brand new stainless log style mani on and it cracked the first week.  it cracked right on the tube across from where the turbo bolts ups. it wasn't the most expensive manifold but I don't think it would have cracked as easy if it were all braced up so I welded the crack up then worked on some proper bracing. before I put the mani in I had already welded a tab on it cause I planned to brace it up good especially for bouncing around on the trails.

[Crunchy Taco [OP]]

I also welded a piece of round bar from the turbo mounting flange to the manifold flange on the top. the next thing will be one more brace from the bottom of the turbo mounting flange straight down to the motor mount bracket. after all that bracing I should be bullett proof

what can you tell me about that oil filter set-up? thats a cooler for the oil? I have that set-up that I pulled off a 3rz that I got hold of. was wondering if I should put it to use

[Crunchy Taco [OP]]

it's just the factory oil cooler that came on that particular year of 3rz. a hard line runs around the back of the motor then down to the cooler that feeds coolant it comes from the other side of the motor the outlet of the cooler dumps back into the block with a short piece of hose. one of the hoses in the pic isn't being used. my hardline that goes around the back of the motor has a hole in it so I ran a piece of heater hose from the cooler under my motor to tap into where the hard line normally feeds for a roadside fix bout two weeks ago. your 3rz dosnt have the same oil cooler on it? different years must have had it and some didn't I guess

[Crunchy Taco [OP]]

if you look close you can see the hard line in the pic that runs around the back of the motor and feeds the oil cooler

[Crunchy Taco [OP]]

if you look at the pic you'll see the hard line with a short piece of hose that normally feeds the cooler then the line in the back that my finger points to is the line that dumps back in the block. then of course the line that's the fix I had to do the other day. 

[Crunchy Taco [OP]]

here's what happens when you buy a cheap header and don't brace your heavy turbo up properly. a week after install. had to weld the out of the cracks and brace the crap out of everything. yay

[:)bestgen4runner]

That is some Gangster  right there. 

[Crunchy Taco [OP]]

anyhow hog canyon if you can set that oil cooler up on your motor it couldn't hurt. I wasn't even aware that some 3rzs didn't have it. all the motors I've had have the cooler on them.

[Crunchy Taco [OP]]

rotated my compresser and change my charge piping around a bit. here soon I'm going to actually get a nice intercooler kit. slowly upgrading this thing
