hi all i am thinking about converting my 93 wrx to a front entry to try and shorten my front mount pipes whats the best way to do it?


cheers david

 

the best way is not the easiest!

Russell (sorting out a rotated inlet manifold project right now!)

 

David, John Banks did a huge huge thread in Projects on this about 2 years ago, killer thread but very informative.
Best take a look at AndyF's thread first though as thing are moving on...
Graham.

 

The best way? Get a spare manifold and hand it over to Wallis or Forrest and let them modify it for you...then fit it...and make all the other little adaptions that are necessary...it's really only worth it if you relocate your turbo too, so that all your pipe work for the front mount is reduced to about 3 feet

 

Scoobyclinic did mine.

 

got a tdo5/6 20 g so i was thinking about turning the compressor side of the turbo round towards the inner wing so goes straight in just have to sort out brackets for the actuator

and the alternator

cheers david

 

hi russell so whats the best and whats the easiest way then ?

so what you doing the rotated manifold on then?

cheers david

 

Dont forget that you will lose the std mounting points for the actuator if you rotate the cover.. (assuming IW)

Rob

 

No he didnt. I did.

And I wouldnt say things are moving on, Andy is doing something different, and I wouldnt recommend anyone except a hanfull off here attempt it.. and Id at least wait for his thoughts when its done!

STD Phase 1 Inlet is good for 500Bhp

I use a modified Phase 1 inlet.

Whats the spec of the car, as rotating the inlet will give you virtually no benefits and 100's of headaches.

David

 

hi david the spec is 93 wrx tdo5/6 20g ,gruppe s headers ,hybrid frontmount ,740cc injectors,decat 3inch system ,apexi power fc and avcr boost kit mapped by andyf. running 340 bhp .(pm you with what else i got)

cheers david

 

Sorry David, frazzled memory!
Graham.

 

lol... old age or friday??

 

At that spec (ie, turbo, hp level), I cannot see any major benefits of rotating the Inlet or the turbo.

Best to maybe raise the Phase 1 manifold on nylon spacers and run a MY97- Inlet hose instead of the 90 degree Samco hose you currently run on your MY93.

Russell

 

Im with russell on this one

 

Having done front entry on several cars, TD05 and TD05-06 20G I have found there is little to be gained over the 90 deg entry. Best results so far were F.E. with a 90 deg bend pointing at the driverside wing and plumbed onto an inlet tract and filter from there.

 

Think there on about the inlet manifold harvey, not the turbo.

 

Think Harvey's refering to this Steven.....

Still to decide if i can be bothered to do front entry manifold.... front entry turbo done tho. Probably go with David on this too and leave well alone

Tony.

 

At least someone listens to me. No-many up here do!

The ones that do have big power figures at the moment (STi7@370bhp, STi5@379bhp, UK MY00@309bhp,etc) but some still rather prefer to go to local "professional" outfits.

I don't bother me as I make very little on doing this stuff - it's only a hobby.

David - Go front entry on the turbo, but LEAVE THE MANIFOLD ALONE!

At least until the 2.5 goes in!

Russell

 

hi russell this is a spare manifold that i have bought so that i can get things ready for the engine change so that i got it all ready just to drop in.

was that kendos sti that made 379?

cheers david

 

btt for any more info

 

On Kenny's car or FE inlet manifolds?

Will your existing FMIC outlets lend themselves to the pipework flow directions required for the conversion? If you have to start altering the end tanks or purchasing an alternative FM then it could add a fair bit of cost or complication.

Do you have access to fabrication facilities as without this it could be a nightmare.
