500hp from a turbo buick v6....that sounds good..I'm a little confused now 'cause both these engines are great for my project.But I have a lot of time to think about what engine I should put.I just have to continue saving up 'cause I know this will cost me BIG $$$.Getting a car is no problem....back in my country I can get a sunny for little cash.Just have to make that the body is in good shape(Don't want to use my current sunny for this....it's too much in good condition to mess it up like that!)

1) the earlier rover V8s are to be avoided like the plague - you want the later post 1984 3.5L or 3.9L - these are the "stiff block" and have massive valley webbing. top stuff here.

2) toymods is NOT the place to go looking for info on the 1UZFE. go to www.lextreme.com/forums/. this is a real worldwide community forum, with everyone being hardcore enthusiasts seriously wanting to help each other.

3) a buick V6 may be great in the grand national, but not in oz. they are both on par power-per-upgrade wise in the US, but the buick V6 weighs more than the 1UZ and requires serious top-end work to stay together at sustained high rpm.

the 1UZ however, needs nothing. 6 bolt (crossbolted) mains, forged crank, forged rods, individually measured and weighted pistons, 4valves per cylinder, scissor cam gears to eliminate backlash, twin elec dizzys, non-interference head (snap a timing belt and you WONT put a valve thru a piston) and the biggest facotry oiling system ever mass produced make this the most understressed engine in the world. add to that that these engines have pistons with ring lands the size of your little finger and you can see why they can take over 1bar of boost on the std internals with the factory 10.0:1 CR.

and in the US, these engines are "throwaway" because they're a jap engine and not "good ol' yankee muscle" . the evidence points to which is superior

so please, don't post bullsh1t and rumours. it's okay to have an opinion - but don't feed the fire of ignorance.

Yeah pro-240c.....you really sound like you know what you talking about.This last post sounds very convincing to me.I take you are a REAL 1uz funatic.All these engines sound like great engines(like the v6 buick),but the 1uz is growing on me like a weed.I get excited just thinking about it.It's most likely that I would go with the 1uz and v160 box.I'm not starting the project right away so I have a lot of time to think about what I want to do.I appreciate everyone's opinions.

i know what i'm talking about when it comes to 1UZFEs - not about putting 200B calipers onto Stanza struts though!

look, the buick V6 is a good engine. as is the rover V8. but that the end fo the day, they are monster torque producers even if they make (comparitively) lesser outright power figures.

but in NA form ,the V6 is less than lacking and the rover V8 revs well but just doesn't produce the goods - regardless of how they perform on paper.

the 1UZ can give you both - monster torque when boosted and massive power - without having to open the engine. they have 190kw from the factory and about 350Nm of torque - in NA form. one can only imagione what difference an M90 / MP112 eaton or a big turbo will do.

the 1UZ is more serviceable as well. ALL gaskets are multilayered steel gaskets - ie you don't have to replace them everytime you pull the engine apart - and the whole engine comes apart like lego.

they have 3 different sump positions (front- LS400, centre-crown and rear-SC400/soarer) and a remote oil filter as standard. getting my remote filter changed to hose tail barbs with hi-temp oil line cost me $AUS114. makes chaging the filter easier and it was the only way i could fit the engine.

FWIW, i'm currently building a twin turbo 1UZFE.

it was my pick over both the rover V8 and the GM V6 - all three being plentiful here in OZ.

sorry for trying to help with the toymods thing... but i was un aware of the other one all i was suggesting was that you could go there because not all toymodders are arseholes and dont help, many of them are good people and are willing to give a hand...

just looked at pro-240c's website, the thing is a weapon! How long did it take to install/tune the steering wheel gear change thing? Seems awesome... If you put such a combo in the lighter Sunny/B310 it would fly, and you would be one of very few that had performed such a modification...

the buick v6 is the same motor used in the VN commodores isn't it? is the 3.8l supercharged ecotec in the VT's the same?

i wasn't having a go at you, just it's hard to get decent advice at toymods coz all the olskoolers like gianttomato and Ed etc don't reply once two or three ricers have added their little useless bit of (mis)info.

the steering consumed about 100 hours. that's trial fitting, cutting, checking, engineering, welding etc etc. it was A LOT of work and i wouldn't do it again unless it was REALLY worth it. then again - i don't have a shed and did the whole conversion in my carport.

:edit: sorry - i thought you meant the rack and pinion change. the tiptronic auto i bought as a kit and will be installed with the delco.

Very interesting info there pro-240c.Man I can't wait to start my project.I'll have to figure out which sump will be suitable for the sunny.I just checked out your website.I'm very impressed.That was a superb job instalingl that 1uz in the 240c.I think the most puzzling thing is the problem you had with the steering box.Do you think that will be a problem with the sunny too?

the 240C has a MASSIVE chassis rail (it's a full chassis vehicle) and the steering box is a super quick (3.2 lock2lock) ratio and is bigger than the std P610/B210 ones so it was a bit of a nightmare. i could have used a 200B one and made it fit but the engineer wouldn't even entertain the idea.

the sunny has a much smaller steering box - but a much smaller engine bay. the physical dimensions on the 1UZ is very close to 700mm x 700mm x 700mm (2 and 7/8ft cubed).

if sump dramas arise, custom ones are VERY easy to make up for this engine. they aren't structural see...!

i suggest you jump onto lextreme and talk to David about borrowing an engine (or knowing someone in NY who will - he's in LA) for a trial fit up.

he'll be able to find you someone who'll help you out - tell him pro240c sent you.

Thanks man.....I'll give him a shout when I'm ready to start the project.You're really helpful.By the way,did you use the std 240c diff or did you use a different one and what diff do you suggest I could use in the sunny?
