Trying to Decide On 1uzfe Extractors - Rush or Castle?

[Cuzzo]

Hey,

Trying to decide on extractors for my 1uz in the cressida.

The current ones are factory ones modified and they keep cracking.(probably because the lack of flex join)

However i have limited room due to the steering linkage to the rack.

I'll try and get some pics today and measurements to help me decide. But im tossing up between the castle auto exhaust or the rush import ones. (or other?)

Castle - http://www.castleauto.com.au/ch85.htm

Rush - http://rushimports.com.au/store/index.php?cPath=6

Is there an other option? The price is right for these..i wouldnt want to go more than 700.

Thanks,
Adam

whats the firing order of a 1UZFE compared to say an LS1? the 4-2-1s (rush) don't look right compared to other V8 4-2-1s i have seen.

Assuming they are wrong, I'd go the castles, not tuned length but should flow a bit better than standard and look more compact.

you using flex joins this time around?

[Cuzzo]

Yeah definetly going flex joins

[oldcorollas]

castle look shiny and give you more flexibility to tailor the pipe going aroudn the steerign bits

Dont forget to factor in any clearance you need should you decide to go manual, as a clutch slave and fork poking out the side of the bellhousing doesnt leave a lot of room as well (its given AndyTTR some grief in his Supra). You dont want to be forced to go for a concentric slave but its a bit hard to factor in since you are still auto.

I take it that if you are consifering spending a bit on extractors that any forced induction will come from a SC?

This keeps getting brought up but i bet it makes absolutely no difference since as you say the extractors are not tuned length anyway

Happy to be proved wrong but it seems like everyone makes such a big deal about it when in anything less than a full-on race engine it shouldnt matter at all.

The Rush ones come in two sizes, there is a larger size which would be the go if youre fitting a blower however were made specifically for the Soarer so there is no guarantee they will fit anything else (aside from a Supra) - i think though he was starting to make some for the US Tundra?

on the contrary.. even a set of tuned length pacemakers make a difference on chev's etc etc vs the stock cast header..

depends what your chasing.. for $700 set of 'custom' pipes there not really going to make any difference at all, cos they won't have merge collectors, or even a step, shit i would be surprised if they were mandrel bent..

steering arms, starter motors etc etc doesn't matter, there will always be a way to get around them.. just depends on how good the fabricator is..

talk to anyone with V8 extractors, and you will get the same names come up, one of them

Craig - Extreme Custom Engineering Brisbane - 3274 3700

people trailer thier cars to him all the time, as other shops have tried and failed or quoted a rediculous price for a set of decent extractors..

[mattysshop]

sorry man, just saw your in NSW.. might be a bit of a hike

don't get me wrong, I'm not saying that the (castle) 4-1s not being tuned length is a bad thing, they have been designed as block huggers and thats what they do.

What I meant was if the 4-2-1s have the wrong cylinders paired (nothing to do with the lengths) then I would steer well clear of them, as it will possibly sound wrong. Simple enough to check if the pipes are paired right.

Of course it would! Anything would be an improvement on stock manifolds, especially on a UZ.... and on a stock or near stock daily-driver engine i bet 99% of that improvement is from having pipes with decent flow and size - whether they are tuned length or have the wrong cyls paired probably makes 1%....

To answer your original question, I HIGHLY doubt either will clear the steering column on the MX83.
Its smack bang where extractors want to be.

[Cuzzo]

Yes im looking at this right now and its making me think the same......
why!!!!

What is a custom set worth? Its like $1000 huh?

would guess so, unless you find someone who really likes welding.

[CrUZida]

Custom ones are usually between $150-$200 per port, depending on how intricate they are, whether you want them tuned length, 4-2-1, 4-1, etc etc.

Because all factory 1UZ cars (except UZS131) the engine bay was designed around the motor.
