NA 1UZ-FE power??
|
Fri, 31 October 2003 06:27
|

the non-VVTi 1UZ going into my 240C is a neat engine with very few kays on it (actually, there isn't even any dust on it...!).
i was looking at using my Kawazaki GPz1100R 35mmŲ throttle bodies on it (2x sets of 4) with a custom top inlet manifold, some mild reground std cams (of the 25/68 68/25 variety) and a nice set of headers into my 2.5in straight thru system.
my questions are
1_ the auto that came with it - to beef or not to beef? will it hold up okay and will i need a tranny cooler? and
2_what sorta power can i expect? i'll have about 300hp with the std engine running with the exhaust and the delco, how much more should i expect? and
please don't tell me to visit www.lextreme.com because most of the guys dispensing on there are about as useful as tits on a bull.
cheers for your help.

My gut reaction is that the 35mm throttle bodies are probably a bit too small. You'd want at least 40, and ideally 45 mm throttle bodies. Maybe see if the 20V 4AGE throttle bodies (beware silver top and black top are different) are of a similar spacing - I was planning this sort of thing for a year's time.
As for the auto, the A340 apparently is quite prone to heating up so a tranny cooler is a must particularly if you want to give it a bit of stick. Can't specifically comment about the beefing up aspect - depends on what you want to do with it.
As for the cams, I think you'll be in for a rude shock. They need to be welded then ground, so as to preserve the base circle. Last time I looked this was a nearly 2K proposition!

aiyo!!! 
that's shitloads just for some mild cams!!!
the tranny cooler...should i hook it up to the oil plugs? (like the return line into the fill plug and the drop line out of the drain plug?) i could prob use the power steering pump to pump it all too, the 240C has that lovely recirc ball steering ...mmm... vagueness. would a cooler out of a kingswood or the like be okay (friend has one he's not using)...?
i wondered about the TB size, but i figured that if the TBs are good for an 1100cc four at 13000rpm then i reckon one would be good for a 2000cc four at 6500 with shorter runners - but times 2 for the 4.0L V8.

The A340E has a reputation for sponguing power, overgeating, sloppy shifts and down-right ornariness when put behind a hi-po motor.
A lot of the Soarer guys get manualisation, shiftkits, histall converters up to full rebuilds from MV Automatics. Tranny coolers are cheap and worthwhile.
I've been doing a bit of reading on this one, cuz I'm hoping to put around 230rwkw through my A340E

i've been quoted $3500 for a full rebuild with a seamless shiftkit - as in you don't know the box has shifted except for the change of engine note - just seamless power.
what are these MV automatic rebuilds worth?
the delco i'm using will program out the retarded engine power during shifts (i think the std toyota comp retards the timing by 10deg or something...?)
would you mind sharing your knowledge so far re: the A340E? it would be very much appreciated....

1JZ, mostly you'll find 40 or 45 mm throttle bodies on 2 litre 4 cylinder engines (some of the more top end crazy stuff might go out to 50's)- multiply that by 2 and you'll have a 1UZ!

Jeez, I wish I knew more about these boxes! I've had quotes around the $2,500 mark for a full re-build and toughen up. I *think* that MV are in Adelaide - but may be wrong on that.
JMS are selling a rebuilt A340E Soarer box for $1750 + $200 for the 3,000rpm convertor, if that is any guage.
Main thing is to fit a BIG cooler & maybe a temp. gauge. The ALSC site has quite a few posts from people who have had their boxes rebuilt.

the ALSC? what's that? Australian Lexus Soarer Club or something  ? what's their address?
i'd love to find out more about them other than "they're shit. use a supra 5spd". people said that about trimatics in their day too...
d'you reckon a power steering pump would be okay for a tranny cooler pump? it's about the only thing i can think of that is suited to such a small pump requirement.

Chat to MS75 - he had the full MV treatment on his A340 and it is now behind his turbo 1FZFE. They are in Adelaide. No idea on cost etc, but he has recently done it, so all that should be very fresh.

GT,
Have you checked out the cams from the Carbontech website for some info?
He says:
Camshafts - (Increase of 50+HP)
Carbontech can supply all shims for camshaft-to-value clearances.
100,000 kms belt change.
Note - Camshafts can be installed running the standard computer. $1,870
How can camshafts mild enough to be run on the standard computer increase power by 50hp!?

An automatic transmission contains a big frigging oil pump as it is. All you need to do is remove the existing transmission oil lines which go to the radiator, and re-route them to the biggest trans cooler you can fit in your car.
As for your "seamless shift kit", you'll find this isn't such a good idea for high power applications. Smooth gearshifts are acheived by slipping the clutches heaps on each gearchange, which leads to more heat due to friction, faster clutch wear, and a shorter lifespan for your box. A box built for high power typically has fast, harsh shifts to minimise slippage.

Yes, you'd need 45mm throttle bodies for each cylinder.
FWIW Kelford Cams on the Gold Coast do stellite re-grinding of cam lobes for about $25 - $30 each, so a 32v engine would cost between $800 and $960.

Ah, questions answered 
Just be warned - while they are all called A340E's, there are in fact over a dozen variants. FWIW, my JZX90 Chaser A340E has a model number 30-41LE. From what I've read, these are got boxes - they're just set up for luxo-barge cruising, so you need to mod them for snappier shifts. Have a look on that ALSC forum - those guys are talking about Stage 1,2 and 3 kits and all sorts of interesting stuff.
Onya,
Justin

Yep, stage 1 kit right here... FAST gearshifts on full throttle. The tail end twitches between every gear when driving hard

where did you get your stage 1 kit done and what did it cost you? i'm very interested.
the seamless kit actually replaces the 1st 2nd and 3rd gearsets with straight cuts and uses more pressure or something to punch the gears in at lightning speed...i asked the same thing.
