here is a shot of the engine snugly fit in the new cowling in the boat.

yeah the Rolco manifolds are fine for the 1UZ if you are useing it as a midmount like Jordy's boat. Trouble is they dont fit for a sterndrive with the risers and big risk or water ingress as the distance from the rear exhaust ports on the engine is only 12 inches away from the transom. You could...

Hi Outrace the hytek manifold risers do come up the centre of the manifold however the runner towards the rear of the boat is a little long to fit properly onto the mercruiser y pipe I would use them however ask for the manifold outlets to be made shorter say about 4 inches.

bought second engine and runs fine. I used engine assy lube on the front journals and gave the engine a quick internal inspection before installing. Making good pressure and runs well. The last engine had alot of metal in the crackcase so i reckon there were more issues at hand. It was out of a...

just on this comment the pump in the alpha is more than enough to cool a 1UZ with a heat exchanger. sits on 70 dgerees no issues. The alphas arent great i admit...but they do mate them to efi 5.7 chev in new boats so no too bad. Bravo would be a nice to have definately not necessary.

ok guys got the boat finally going again...been a long project this one but well worth the wait. Im going to post some photos on the site and some video on monday 3rd jan 2011, but im very pleased with the result. The power gains over the chev 4 were amazing (not surprising since it was only a...

Nice boat Mike, the 1UZ in the Epic is a much different looking animal to the car engines. Looks like it has a plastic intake manifold as well. Im just finishing off the second 1UZ install this time with HITEK stainless manifolds, as the last engine has a seized camshaft journal. Looking forward...

ok better to be safe than sorry again...i'll pull the cams and have a look round first seems like its an ongoing issue for motors which have had some downtime...

I have been reading alot of posts about seized front camshaft bearings and its seems its becoming a bit of an epidemic with these engines. I have had mine go recently on a converted SC400 engine in a boat. Im about to put my second 1UZ in the boat and I was wondering if theres anything I can...

edit to my last paost...maybe thats the key just chuck 4 engines in your car LOL

Rod Im sorry you copped a raw deal from Yavuz. With the time and money invested in engines and cars these days it easy just to put our hands up in the air and say Ive had enough..Let me know if you find someone good. The reason I stayed with a std ECU setup on my boat was due to the fact dyno...

Rod Ive had 2 or my race cars at Yavus at Unigroup Engineering at Girraween. First was a Nissan race engine runing twin 40 webers and second race car was a Sr20 with quad throttles and SM4. Both engines made exeptional Hp for their work and size and perfromed equally well on the track. I know...

to spf_lexus, that was my engine which had the passenger side cam bolt break due to seized camshaft. Its very hard to determine over a forum what could be wrong with the engine...in my case I had alot of suggestions as to what it could have been but who would have guessed it would have been a...

yeah !! who whould have guessed that one.....Gloverman said on another post that engines which have sat for a while are susceptible to the cams seizing. This engine has been sitting for 2 yrs since I took it out of the car. I however think that the Soarer I took it out of took a big impact and...

Hi guys looking for an SC400 1UZ engine in the greater sydney/newcastle area in NSW AUS. Please PM me or call/txt me on 0400695955. Loom /ECU etc not essential, just need to know it was going when pulled.

ok all is now revealed, the motor wouldnt rev past 2000rpm under load and did not have any power. Took it to Sideshow and he was pretty quick to spot the fault, seized intake camshft left bank. Actually it broke the bolt holding the belt pulley on the cam. The engine amazingly still idled but...

My motor out of an SC400 was seized in the camsshfts after sitting for a while...darn it.

No probe I doubt it's fuel press reg as it would not fail at 4000 rpm and I've never seen one fail in over 100 1uzs if engine doesn't have a miss all way up to 4000 then doubt it's injectors It seems to miss all way through the rev range now with a knock... Has timing belt been done Timing...

thanks heaps Sidey...looking forward to Tuesday. Ill bring the Carlton Colds and a wad of cash. Im hoping its something really simple. As you have said in past posts this engine has sat for 2 years so sticking injectors, low fuel pressure due to a faulty reg could be any number of things. too...

Thanks guys, went to Diag plug and W pin in missing and E1 does not have 12VDC. So I have it booked in to see Sideshow on Tuesday the 27th so will see what goes...
