I have got a my94 wrx and im buying a hybrid intercooler second hand from a member off here.Now i just need to know what are the best rated induction kits to buy?
So could you please recomend me a good induction kit?
Im going to be running mafless and i will be running around 500bhp in time,so i want to buy the best one for my needs.

Cheers for any advise.

 

apexi all day long bud

 

Go for the biggest possible i.e. one of the two RCMS K&N cones with the 160mm flange to attach to a tuned spun alloy induction trumpet. Best possible... Also prob defo needed if you intend to go for 500bhp later on...

 

BIG APEXI Then!!!!

 

I have been looking at the rcm one,where could i buy a spun alloy induction trumpet from?

 

You can't get a "big" Apexi cone with the 160mm flange, as far as I know.

Apexi do do an IK called "Power Intake" but I think they've only been mapped to around 400bhp...

 

Here: Ally tuned induction trumpet

Choose turbo end's diameter - either 60, 70 or 75mm (likely to be 75mm/3" though) - that is closest to your turbo intake pipe's diameter...

 

Thanks for the link.

So if i order this rcm one. http://www.rogerclarkmotorsport.co.u...productID=1151

And the induction trumpet off ebay with 75mm end it will all fit together on my car?or iam still missing something?

 

Sorry Joz - I was messing about - shame though!

 

No don't get that one - it comes with its own! trumpet which mates to the MAF - but you're deleting the MAF!

You just need the air filter on its own (so as to mate to the trumpet in my link).

Here are RCM's the two 160mm flange'd cones: http://www.rogerclarkmotorsport.co.u...?catsLevel=183 (the top two items on that page).

One is long, the other is shorter - check out their dimensions and choose the one that will best fit in the space in your engine bay...

 

lol no worries. I thought you might have been joshing - but thought I'd better post my, <ahem>, "wisdom" , just in case you weren't.

 

Ah i get it now,i was thinking that the first induction kit didnt need a trumpet and i was get confused for a minute then.Thanks for the help joz i will order that trumpet now with the 75mm end and then see how much room i have when i get my back from engine turner.

Thanks again.

 

Obviously, you'll need a short piece of silicone hose and 2 jubillees to mate the turbo end of the trumpet to the turbo intake pipe.

Indeed, that silicone may have to be straight, 45-deg, 90-deg or 135-deg, depending on where the space is in the bay.

But if you're getting it all fitted/mapped at Alan's then leave it with him (he'll be stocked with silicones/joiners/clips, etc...)

 

Would i not be better off buying the rcm 80mm trumpet as it must be better quality than the ebay one?or is 80mm to big to fit on to the silicone hose from the turbo intake?

Im going to give alan a call tomorrow and have a chat with him about fitting the fmic and induction kit for me when my engine has run in.

 

The RCM trumpet is loadsa money by comparison -- that other one is only £26 delivered.

I can't remember if the turbo hose is a 75mm or 80mm OD. But, whatever, a silicone joiner with an 80mm ID will clamp round 75mm OD if tightened enough, so not an issue.

But Alan will know, anyway....

 

Thanks for the advise joz you have helped me out.

 

what power are you running now? so you need an induction kit?

 

Im having a 2.1 forged rebuild at the moment and im going to get a hybrid fmic fitted when the engine is run in,thats why i need a induction kit.
