Check out what some of the Puerto Rican's do with 3t's..... http://www.rollaclub.com/board/topic/16233-toyota-pics-from-puerto-rico/page__pid__536784__st__120#entry536784

Hey mate, I may be a bit biassed on this but definitely worth doing. Personally I think a well sorted 4k or 5k turbo with a decent amount of boost is actually quicker than a 4age. The motors are a lot strong than what a lit of people say (typically people who have never actually turbo'd one). Provided it is well tuned, particularly the ignition side of things you can run a fair bit of boost through them. Mine runs about 16-17 psi but I regularly spike to about 22 psi - my ecu has a data logger. I just about to make some major changes to my setup and get it running about 23 psi. To be honest the fun doesn't really start until about 10 psi. To answer so of your questions more specifically: I don't think it would be worth trying to cut and shut the intake manifold. The port spacings would be all wrong and the injectors would be right at the end of the et runners meaning you'd have to mount them in what's left of the k manifold...then you'd need a custom fuel rail. You would be much better off trying to source a 7ke manifold off a townace. Again with the exhaust manifold being cast iron it isn't really possible to cut and shut it. Custom made manifolds like mine can get pretty expensive, however a j-pipe setup (off a single outlet Ke70 manifold) relocating the turbo to where the battery normally sits can be done relatively easily and cheap. Just make sure its made of steam pipe not mild steel. Depending on what Cam you are using I personally think a t25 is verging on too small for a 4k or 5k. Use it in the meantime though and you can easily swap it out for something a bit bigger with the same flanges later on, eg a t28. The fuel system is relatively straight forward - same you would do for any efi motor swap. You'll have the fuel reg from the et too. Have a look through my project thread, I'm on my third turbo setup now, now with efi. Should be able to get some ideas on how to tackle a few things cheaply and how to get a little more serious as well. ;)

Yes the gear box will bolt straight up....but you'll have no drive as the ke10 gearbox has a smaller input shaft. I can't remember if the clutch diameter is smaller or not, don't think so, so you should be able to use either flywheel but with a Ke10 clutch plate.

Ohh ok what did you use? I tried using a small grinding wheel to go out to 3kbp size. Made a mess of it.

I hope you're not going to try and port match that 7kc manifold gasket? Being 3 layers the edges all bur up.

Fyi the 'insulator' between the pump and block isn't for heat insulation, it makes the throw of the pump arm correct onto the Cam. If you don't use it you'll snap the arm off the pump in a minute or 2. As above, might be a vacuum issue. Does it have a standard charcoal canister setup? If so maybe disconnect it for a minute so you know the tank can breath...or remove the fuel cap as above.

With the gearing in my t50 and turbo 5k I can push over 200. That's about 1000 rpm off the limiter in 5th.

Getting a bit ahead of yourself there I think..... Was this a ke70 k40? because a ke30/55 k40 has a different shifter again.....which also has a different shifter to a ke30/55 k50. You make it sound like every k40/k50 has identical shifters which is very far from the truth!

If they're the later type (ae86/ae71) you could just get one of the trd short shift kits off Ebay.

That's actually a 3k dizzy, could be why you can't get one that fits. ;)

Your friend is very wrong. There are about 4 or 5 different ones including the electronic dizzy ones.

Let me know if you would be interested in selling 1x of those! I need to find a 15" spare for my 55.

Called a 4ku and extremely rare in Aus

Ahhh...thought that might be the case... Your machine guy is obviously comparing this head to a 4k head. What you have is a 5k head! It has been shaved maybe 40-50 thou - you can tell by the recess below the Toyota emblem in the last pic.

Can't see that pic.... 30/55?

Start by getting the wheels balanced again.

Yeah that's the type of disc I'm using. I read on some Nissan forums that some rb & vg engine owners could suffer top in misses caused by timing belt slop through the 360 slot reference trigger. I am only going to use the 4 slot sensor with an extra hole drilled after 1 to give a cylinder 1 dual pulse. I have another custom cas made from a k lower dizzy half welded to the top of a stanza cas. I wired it to my ecu and tested it, worked well but I then discovered the welded housing was miss aligned. Hence I've started again and retro fitted the sr20 sensor into a k housing. I'll be uploading a whole heap of pics of it in the next couple of weeks.

So with your new flywheel sensor setup you're still obviously restricted to a waste spark setup and can't run quad coils? I'm just about to test and fit my new hybrid k/sr20 cas so that I have a dual pulse Cam sensor. When you say your Nissan setup was a bit temperamental were you just using the 4 slots or a combination of the 4 and 360?

Oh btw what are you using for the ecu trigger?

Yeah looks a little lean, throw the plugs in and see how it is (you'll want them if it fixes the miss or not) and if it doesn't sort it out get the new squirters in. 440cc will be plenty big enough. Really happy with the cas, machine guy did a great job, even machined me a cap out of Teflon. Will cost me an old bumper from the shed and a six pack! I'll upload a whole heaps of pics soon but I'll text you a couple in the meantime.

A little further down the pipe should be ok....where you've marked it I would be more worried about clearance on the under side of the floor!

Hey Leigh, have any improvement with the other plugs? Cas is finished now btw, just gotta pic it up from Hobart.

They're what are commonly referred to as the "D dish" pistons which have a volume of about 22cc. The OP has "O dish" pistons which are normally around 6cc.

Crow cams do grinds with whatever specs you want for about $120 if you send them a stock shaft....which should only cost you $20 odd. Maybe put up a wanted add for a stock Cam and request the seller to post it to crow. You could then deal directly with crow via email and Paypal and get them to post it to you.

That's definitely a 5k head, you can tell by the lugs under 1 and 4 spark plug holes. Your pistons also appear to have a bit of a dish in them. Maybe you actually have a 4ku!? A 5k head on a flat top 4k would normally raise the c/r far too high.
