are all jdm avcs heads regarded as 'big port' ?

heads in question are from a 2002 version 7 jdm wrx sti so will they be better than say sti8 uk avcs heads

cheers

 

Hi Mark

Yes all JDM V7 onwards are big port including JDM WRX heads,although JDM WRX have lazier cams than STI off course

And yes they're better than UK,but they're more to prone crack around spark plugs due this I would check them

Jura

 

they are from a jdm wrx sti so will they have better cams?

p.s its matt not mark

 

Yes JDM STI have better cams than UK STI and you will have higher rev limit too(8250RPM)

Sorry again for misquoting yours name Matt,this happened to me few times on yours name

Jura

 

thats good news then,im gonna rebuild them anyway using supertech valves and seals before they get fitted,trev @ realstreet has done me some good prices on supertech items along with my crank/rod and pistons

no worries about the name mate......i answer to most things

 

That's awesome Matt,if you are going with better valves etc,do you thinking upgrade at least springs to something better like Kelford etc.?

If you are going with better valves extra 280USD is not too much for valve springs

You will see how you get on,but good luck

Jura

 

yes may aswell do springs aswell,how about these

i want to order everything all at the same time so i only have one shipping cost to pay,another member on here is also ordering a load of stuff so we are splitting the shipping/import tax cost and as said trev has done us fantastic prices so we are saving a lot of money by ordering from the u.s

 

Hi Matt

Personally I would go with Kelford KVS109-STi,we have used them on our 2.35L and Neil recommend us them

They cost around 270USD over on eBay and Real Street Performance(RTS) are dealers for Kelford,just ask him about them

Agree saving buying parts from US is just big to miss,as we are all parts usually bought from US,but we are used No Limit Motorsport in NY

Jura

 

hhmmm not seen kelford on their website,i will drop trev an email and ask him

cheers for the advice jura

 

Hi Matt

RTS are dealers for Kelford,I'm sure,because I've spoken with Trev few months back when we are went with 2.35

They don't have springs on the website but can order them from their warehouse what I know,when we are spoke with them http://realstreetperformance.com/Products/Kelford/

Drop Trev email and you will see

Thanks,Jura
