im doing a ka-t im going to be running 5 pounds on a 162000 mile motor has bad valve seals exc. i am building another mototr on the side for higher boost and more power what do all of u run internally? and have any of u ran 5 pounds with sr injectors and a walbro fuel pump with a fuel pressure regulator and didnt need a safc? also what can u do to make those dam ka oil pans from leaking? no matter what i do they always seem to leak. and out of curiosoty what are u guys running as far as your kits?

 

this is my first ka-t

 

Building a ka-t on an old ka is a really bad idea. it's just going to make those little problems into really big ones, and eventually you'll be left with no daily driver. trust me, if its an old motor DONT TURBO IT. I ran my setup on an old motor while i was having my motor built, and within 200 miles i threw a rod through the block.

SR injectors + walbro means you're going to need some major tuning. i'm not sure an safc will be able to do the job. i'm not sure on that cuz i dont have a lot of experience with those air fuel controlers.

to make oil pan stop leaking make sure the block surface is extra clean, make sure the oil pan is extra clean AND FLAT, and use the gasket + lots of orange RTV. Cheers

 

thanks man, i do have new rod bearings though

 

Rod bearing clearances are critical. i would not recomend trying to change your bearings on your own. that needs to be done in an extremely clean and temperature controlled room.

 

if your valves seals are shot now, DO NOT turbo just yet. It will make the problem worse as now you are adding pressure against them. trust me, thats the whole reason I did a rebuild. I blew my valve seals and it smoked like a damn freight train. I would honestly recommend pieceing together a kit as money provided unless you have 3500 right now to go slap down on one. piece it together over time while your motor is getting built and then be ready to rock and roll after its done. I personally am running 9.5:1 ?? weisco pistons, stock rods, new timing set, bearings, etc.

not correct. SAFC will control up to 550cc injectors, Im using it right now on 480's and it works great. I would recommend planning ahead of time what you are shooting for HP wise. Buy the injectors now that will support the HP your shooting for so you don't rebuy the same components everytime you want to take your car to the next level. So if you want 300ish HP but only have the components right now to take it to 7psi, ~220HP depending on turbo, then don't settle for 370cc injectors which will make you your 220 all day but opt for bigger ones so once you get the tuning and components required to take it up another notch you don't have to go buy injectors again to support your goals.

If you have any specific questions feel free to PM me, I built my turbo kit from scratch doing most all the work myself (With the expertise of Dan as well). <--- you could PM Dan as well, he has to be on of the most knowledgeable person about KA-T's I've ever spoken to and Im sure he'd be glad to answer any specifics.

 

the myth of 550's on an s-afc has been debunked now, btw. i ran 600s on it and lance @ JGS has tuned 600s and 650s on it. it wont work on every setup, since some setups wont require that much fuel and even at -50% fuel you wont be able to get it to work. but s-afc's dont help timing control, and actually will throw it way off.

playing with base fuel pressure won't help. if u bump it up to help with boost fueling, it will still be jacked up across the board even off boost and you'll run pig rich everywhere. bye bye gas mileage and hello sooty melted rear bumper i only recommend fuel pressure regulators on cars with higher HP that may need that in the tuning, but most ROM tunes and such these days are so spot on they can work with the base fuel pressure (and a properly sized injector will negate a need for fuel pressure changes).

im either going to be looking for another long block, or maybe just get a fresh head or get mine rebuilt soon since my valve seals are getting worse, but still only on startup. i only wish i had the money for a full build.

if i were you, do the built motor first. then u can break it in n/a while u piece the turbo kit together.

do it right or do it twice.

 

a friend of mine had a turbo ka-t w/ 215000 miles on it and the owner befor him spayed it alot and it didnt blow till like 4 days ago he had it on 8 pounds and blew his head gasket

 

i already changed them at the shop i work at it was no big deal i mean my girlfriend was even helping put them in

 

i also have a turbo kit that i made for it and im slowly rebuilding a motor on the side but i just want to boost the one i have just for the hell of it ill only be running 5 pounds or so and if i get ambishus anough ill tear off the head and replace the valve seals its no biggy.
