both pipes go silly ways.. compressor outlet could at least come straight under it.. depending on alternator position

David

 

Centre piece wont turn round because its not symetrical, Would be easy to fabricate a new ctre piece though, the turbo thats on there is not there latest rotated mount DR version which does go under the manifold. Good to see however the intercooler feed pipe doesnt now take the inner wing route and try and pop your headlight out like mine does.

Does it have throttle bodies?

Conrad

 

surely it must rotate, and still mate up if you flip it on the horizontal and the vertical?

 

Good Point Steven......DOH ! One of those moments again. Nice thing but I need two entry points, one to each plenum

Just like Jun, they are still doing the plenums wrong and phasing the pulses unevenly. It should be 1&2 and 3&4 that are paired up as they are 360 crank degrees apart and will not interfere with each othes pulse shockwaves, look at the way the spec 'C' splits the exhaust pulses.....similar logic applies......all IMHO of course !

Andy

 

sounds quite awkward to do though?

 

conrad, must have t/b's

david

 

Yeah, I agree David, you can see the butterfly spindle sticking out on the left habd side front one.

Conrad

 

Dont agree Andy, low speed / low rpm maybe so but at higher RPM the time between degrees "gap" will be minimal and thus pulses non existant, the plenums are similar sized both on the JUN & the APS but the APS are not tapered due to plenum being fed from the side rather than the front as in the case of the Jun item. I would suspect they are merely acting as a resovoir of charge to accommodate the demand at peak HP. According to APS the standard inlet manifold only becomes a restriction for cars over 650 HP (the higher RPM range).

What it will do though is distribute charge alot more evenly than the spider leg OEM manifold IMHO.

Apparently not available in production for another 9 months.....

Conrad

 

Update, not much happening just yet but....

Throttle bodies have arrived.
Adapter plates to mount throttle bodies in development.
New means of Forced Induction sourced.

Finished the book I was reading and now I'm in a better position to calculate...

Optimal Exhaust Header Lengths
Optimal Inlet Tract Length

Dry build of short motor commencing this week hopefully

Conrad

 

what book??

David

 

Book...

Whats this about you being bored of cars man, get your **** in the car and get it off the drive, the enthusiasm will return within 1/4 of a mile i'm sure!

 

The green book.

You will be interested to know the NOS only impreza shown is the C&V drag car which now sports a turbo.

Paul

 

if you want hoses making I have a contact

David

 

Paul, yes the green book, read it from cover to cover, learnt alot I think

David, will need hoses at some point, turbo oil feeds, new fuel lines etc. Bit too far in the distance at the moment though. Will bear it in mind.


Do you think it will look stupid with the plenums stuck out of the bonnet? LoL

 

Conrad,

You want to get yourself a new age car, they have lots more room under the bonnet, there was a nice sti 8 in the for sale section a while ago

Green book is good, but I would say some of the recommendations are very conservative, the blue book is also very good, as is the purple one if you're into 2 strokes.

Paul

 

Thought about that Paul LoL, looks nice that one


Enjoyed green book, thought about the blue and the red one, as for two strokes done my time with them thanks,

Hows the adapters coming on?

Conrad

 

Still waiting........engine builder due to start next week Now where have I heard that before???

 

OK, Thought I'd update the thread a little.....

Big Engine is currently being built (At Last ), The STi 8 has gone and made way for a nice family vehicle. Now thats sorted out I needed a project car to fit the engine in....managed to buy myself a reasonably priced MY96 WRX wagon.

Here its is before I started working on it.



And Another...



And Another...



And Another...



While thats been happening I've been buying the rest of the parts required, first things first I want to convert the front end to the facelifted model so I have been buying bumpers, crystal lights, crystal sidelights, wrc style grille and crystal indicators Pictures of these parts later. When fitted and after the paintwork

In the mean time heres a few more of the ancillary parts

Rotated Mount Garrett Turbo Downpipe, clears 6 speed box, and 4" spun trumpet and K&N filter



Turbosmart Blow Off Valve and One Pair Of My Throttle Bodies And Linkages



Slip Jointed Up Pipe For Garrett Turbo (Rotated Mount) and Helix Catch Can



Specially Machined Crank Pickup Wheel To Suit DTA ECU and Four STi New age 500cc Injectors. Car will also run 4 further 650cc Injectors,picture to follow.



Air Injectors which Control the External Wastegate ala WRC cars , SX fuel reg to the right.



Gruppe-S Headers With Modified (read flat) flange, wrapped and ready to go!



Turbosmart External Wastegate - 42mm



Two Bosch Fuel Pumps and Kevlar Timing Belt



Intercooler And Radiator



Intercooler And Radiator From Another Angle




Paddle Clutch - Specially Made to handle The Power



Clutch Cover



Garrett GT Based Turbo




Thats all for now people.......

 

is that turbo going to be big enough???

 

In reality? Probably not

Conrad, have you been sneaking down south and into my girlfriends garage during the dead of night to take those pics? Too many bit's look mighty familure

 

I hope so, the next size compressor cover wont fit under the bonnet...LOL

Not to worry, the 150 shot of NOS will add any extra power required

Conrad

 

how much power are you looking for??

And is the 150 shot of nos for turbo lag

 

As much as the turbo will give Then the NOS goes in!

Lag There aint no lag when you drop a paddle clutch at 8000 rpm

 

UPDATE

Engine is out of the wagon and SOLD, Gearbox has been removed but has not been sold as of yet.

This week......

1. 6 Speed Gearbox is being fitted
2. Paddle clutch is being fitted
3. Propshaft is being shortened 60mm.


With the length of time the BIG engine is taking to get built I have decided to undertake a small project to get the car up & running. We are going to fit the STI Version 7 Engine (That I was trying to sell to no avail) into my wagon this week complete with STI Version 7/8 Wiring and ECU (to control the AVCS). It will be supported with the large intercooler / radiator assembly as seen above, a TD05 turbo and new up-pipe and down pipe.

Hopefully by Friday the engine and box transplant should be complete and all bolted up with the new Group N / Prodrive mounts.

Additionally, to run the big intercooler I am going to turn the new age inlet manifold round so the throttle body faces the front of the car, this will require a spool piece making up to change the angle of it and stop it catching the bonnet. Hopefully this will get done this week also.

 

Cool

 

Ive got some bits in the car for you..

David

 

Cheers David

Oh you meant Conrad......

 

Nice try.

 

LOL @ You two

No worries David, I will get chance to come and get them at some point If you see Mark before I see you please pass them onto him as I'm more likely to bump into him whilst stuck down 'ere in in shandy drinking country


Version 7 loom all over the floor......OK who cut the OBDII diagnostic port out the loom? Come on, own up, I said own up..... DOH!
