At last someone with a bit of sense. Good man

 

Shane you hit the nail on the head!

 

I see the point of course, but is it not a case off good old trading?

Supply and demand? People want these heads for their 2.33/2.5's so the demand pushes the price.
As an owner of a real Sti v3 I'm sitting preety good for the 2.5 affair when it will arrive, so easy for me, but if you do need such heads are they around now as they were 12 months ago?

As an aside, is the big block impreza craze over?

lol

 

oh well i have now got myself a pair of sti typr ra heads from and they cost me £300

hehe

 

Ok, fair enough, now I know where I stand.

Shane : (or anybody else) I need a set of STi 3 or 4 heads, not for resale but for an engine build I have in hand. I will happily pay £450 for a set in good condition, complete with cams etc., don't mind skimming them to flat.
I have been looking for these for several months and time is now rolling on. To get the last set, I had to buy the whole car, damaged, and I am prepared to buy a complete engine if necessary to get the heads. While I have been looking I have been offered two pairs of heads, one scrap and the others UK97 or 98. The casting is the same as far as I know, the valves and cams are different. On the STi the shims are under bucket. UK are over the top.

These and to a lesser extent, STi 5 and 6 heads are popular with 2 litre rebuilds and particularly with 2.5 builds where a short engine is available for reasonable money from many sources. 2.5 heads are not available on the second hand market in the UK, hence the popularity and shortage of STi heads.

Much the same happened with TD05 turbos. These were available for £100-£150 for conversion to 05-06 20G. Those with an 04 upgraded to an 05 and those with an 05 or VF23-28 were upgrading to 05-06 20G. the short supply now means that 05 turbos change hands for silly money.

I look forward to getting a set of STi 3/4 heads for sensible money.
Cheers. harveysmith1@btopenworld.com

 

Likewise Graham - I was planning a 2.5 conversion this winter till I ran my standard V3 (decat/k&n) on the dyno and it managed 326bhp Think I'll just leave it alone for now....

 

Yep!
StiV3 with 20g and the right support and mapper (AndyF of course) and 380 x 360 on Optimax +NF, oh, and 8000 rpm too which is very useful on a hillclimb run.

Given that a "good" spec built engine would ideally use different profile cams, replacement valves and have the castings ported to increase velocity I think its sensible to just buy a pair of underbucket shim heads regardless of what year of car they came from.

If your looking to just bolt on some "out of the box" good heads to a 2 litre then these are for you.

In terms of price, they are indeed worth what anyone is willing to pay, depends how badly they want them

 

Conrad, Putting phase 2 heads onto a 93 or 94 - ish WRX is a very time consuming exercise - can be costly too if the owner enthusiast / mechanic is working from a home - and ending up having to take it to a ' specialist ' to get it sorted.

Sure, any bare heads will do, then a set of valves, then springs and retainers and then cams and buckets That will get it sorted but almost certainly not with any cost saving over The 'easy' way. Try to put ph 2's on a ph 1 set up and you'll need all the inlet manifolding, with all electronics and loom attached, a front entry turbo, an induction pipe and an induction kit. You'll need the pulleys too. That sounds like a never ending nightmare to try and attempt as an amateur. Then what head gaskets should you use?, an amateur will not know that and possibly bend 8 of his nice new freshly shimmed valves..............

Then some modified cams need special shims to obtain a correct clearance. What does the home enthusiast do anyway when it comes to reshimming an engine? he's only got 16 shims. Measure them and wait for some to arrive from the likes or me or you and hope that he's measured correctly??

Our price for a set of vers 3/4 or vers 5/6 heads may not be to everyones liking. However, I am talking about a fully rebuilt matched pair complete with cams, valves springs , reshimmed, fully prepared, ready to bolt on. Crack tested, pressure tested and warranteed.

See if that matches a ' private sale '

David APi

 

Actually mate.. Yes the clearances WILL change. Belive it or not heads twist when they are bolted down. This is the reason clearances should never be set-up on the bench.

Good luck with your sale, i bought a set of V3 heads yesterday, inc cams, lifters and rocker covers for £350.

 

David, I totally agree with what your saying and am not sure where you are coming from in terms of the "private sale" thing or any of it for that matter but I think you missed this bit of my post


Regards

Conrad

 

still for sale, open to offers

 

yep set of complete pair v5 sti removed from 70km type r.

 

Renno Rannes is looking for a set of STi 5 heads.
As I have not been inundated with offers of heads, STi 3/4 for £450 a set I guess there are not many about, certainly not at that price.

 

Thanks Harvey. I know Leggy STI ill be talking to him later

 

anyone want to bye these cylinder heads ? open to offers via pm plz

 

bttt

 

the scoob heads are not like conventional heads.. ie. they are short and fat and the flex between bolted down and not bolted down is very little unlike more conventional heads and the valve clearances are not altered outside of tollerance.. Besides if you are saying the valve clearances need doing when the heads are bolted down then they will have been done when bolted down.. so removing the head the clearances would be out and then bolting them onto the new engine they would be correct again.. if that were the case

Clearances should not be altered therefore by removeable and refitting to another engine imho..
Simon

 

JGM and others,

We do find that shimmed tappet clearances move between doing a head and fitting it. To the point where we only do valve clearances once the head is bolted to the engine. There seems little point in doing the job twice if we know they are going to alter.

However, I do agree that once a set of heads have been done correctly, they should transfer from one engine to another without a dramatic change.

David APi

 

mine were still within tollerance.. but then you have done more than me David.. so take your word over my one off

I actually need to ring you on a related subject.
