Looking good Bev/ Kev

 

Where you not tempted to just lose the whole flange Kev? It would've left a larger margin for adjustment when it comes to the final fitting surely?

 

thats some top quality workmanship on the intercooler

 

Carl, i think i just wanted to prove that it can be fitted without major surgery to the DV mount

David, he fixes motorcycle frames and he's cheap

 

did cack all this weekend, didn't have the fuel reg and new turbo->IC piping so went out for a blast on my motorbike instead, what a shame


i did notice while looking athe the 2 inlet manifolds next to each other that's there's a difference in casting quality, the STi one is extremely smooth inside and has been ported to match the gasket, while the UK one is really rough casting with no porting at all. got some pictures i'll upload later on

 

flat4 who are you using to insure your STI Type RA?

I've just bought one and am having trouble finding a company who has the exact model listed on their database. Mine's an STI2 Type RA (actually it's a 'Limited' but i've got no hope of finding that listed ).

Also, have you declared all of your mods? Feel free to PM me if you'd rather not answer that here.

I'd prefer a mod friendly company as I want to be honest and mine's already got a decat and induction kit; and will hopefully be getting an Apexi PowerFC in the near future.

Cheers

 

 

Iwan:

Call Footman James in the West Midlands.

I'm insured through them.

They undestand the Grey Cars, the mods etc.

I have EVERY mod declared to them and the pain was very minimal.

Graham.

 

Cheers, will give FJ a call in the morning.

Do you have a number for them, the ones on their website don't seem to work, like they're missing a digit or something.

I'll have to start my own thread soon.

I think that is specific to the WRX RA, and possibly the Early STI RA too. Mine was the same, the porting is actually CNC machined, not some guy with a dremel.

lol shame it had to go, but needs must now, should i try and rescue the 5th injector?

 

right, question time again

1. does the wiring loom off the phase 1.5 manifold fit my existing wiring? i ask because it's easier to fit this to the throttle position sensor than butcher my existing wiring that came off (might of answered this myself as i have the individual coil packs wired up in my existing wiring)

2. am i alright to fit my 440s + new IC + fuel reg/pump and still run the existing apexi standard map before i get it remapped? or can i adjust it myself to get me places beforehand?

 

1. believe you have hit the nail on the head with the coil wiring being the problem.

2. The Ic and pump and reg shouldn't effect it much, being MAF based the intercooler change should be fine, would need to watch the knocklink on spool up and on boost etc.. probably especially in 4th and 5th at around 3000rpm at a guess. Hopefully the maf would cover it.
The pump and reg if you set the pressure to standard shouldn't be a problem at all.
Need to work out the rescaling of the 440's and apply it to the 380 map and it might run okay.. but probably need some tweeks but may get you about in the short term/to the mapping location.

 

well at least i have the correct plug for the throttle sensor, just a bit of wiring to be done

 

all fitted apart from the IC (waiting for new silicon hoses) Inlet now ported & parallel'd, went with Y pieces over T for better flow (well thats the theory ) also removed the crankcase PCV system to the inlet manifold



FSE fitted



managed to connect the throttle position sensor up correctly first time it would seem, throttle cable proved interesting as it wasn't long enough to use the standard bracket position so took the hacksaw and hammer to it and mounted it closer decided to bung the old IC on to fire it up, started first time and no fuel leaks just guessed the fuel pressure at 2 bar (think it might be 3 as standard in hind sight) seemed to run ok, tick over was a bit erractic but guess thats to be expected with it not being mapped to the 440s yet





anyone know how to adjust the standard power fc map from 380s to 440s? what fuel pressure should i set it at? all just so i can get around in it for now

 

also, the fuel vent hose, what am i supposed to do with it? i just chucked one of those one way thingys on it for now (might even stuck it on the wrong way)


wish i'd chopped all those mounting lugs off the inlet now at least 200g of weight saving to be had there

oh yeah, and i removed the throttle/ICV water feed while i was at it

 

Flat:
I just blanked the tank vent off. Seems ok.
Andy F set my FPR to 3 bar running just before the mapping. I did this also before to test for leaks at running pressure.
To run/start in safety I set the FPR at 2 bar.

Pipes look good!

Guess your car ticks over too....wish mine would

Graham.

 

If you blank the tank vent off it's usually not a bad idea to drill a small hole in the filler cap to compensate...although I never bother and my car seemed to run ok, then again I was using a Link ECU which is a little less sensative to change

 

All seems well on my Sti but I think the cap seal to the tank neck is a bit naff, so maybe it gets by?
I've got a tick-over!

Graham

 

Nice to see progress Kev. I'm almost tempted to have mine in bits again...

 

you said almost



should see some more progress this weekend hopefully - cue rain all weekend brakes are almost there now (think i said that a month ago )

 

all done engine wise managed to get the silicon hosing i needed to replace the maf to turbo (OEM black plastic thing had too many holes in it) and the turbo to IC (standard hose wasn't long enough) all made to order yet again the IC is pretty snug so i might just make one bracket up for one side just to hold it in place, strut brace won't fit this time though but already knew that from 911's exploits managed to alter the power fc for the 440s and set the fuel pressure to 3 bar and it ticks over ok, took it quickly around the block and everything seems ok (makes a nice chip on gear changes without the DV ) next job is the underbonnet scoop, some heat sheilding for the IC and a redesign for the water spray

 

That looks excellent Kev.
The fit to the bulkhead is even closer than mine!



Are you having it fully mapped by a wizz-kid like AndyF?
I think the full map is miles away from the 'get you going' map in the FC.

Graham

 

flat4 can you pm me what size the turbo inlet hose size is and where you got it from.
Many thanks

*****

 

it's mostly due to the DV inlet i left on Graham although there's still some space left behind unlike when the phase 1 manifold & STi5 TMIC was on

mapping is being done by someone on here, im the guinea pig as he's not done a power fc before but im confident of a good setup


*****, my mate organised the hosing for us, i'll point him towards your post, he's got all my measurements i gave him over the phone so i wouldn't know off the top of my head


off into the garage in a mo to do a bit more work on the brakes, can't finally fit them until i have some tyres on my volks

 

Can I do this kinda engine modification to my import WRX 94?

regardles of above question damn cool thread, I just read from start to finish enthralled, I have got access to a few write off cars so would not mind delving into what you are doing.

btw hasnt your engine got a dump valve fitted anywhere?? if not isnt the noise in the turbo a pain in the ***., when pressure needs to be released?

ste

 

you can do it to any impreza with the right bits (sports excluded obviously ) no idea about the dump valve, we'll see i guess

 

Cool I am stoked now, I am going to start looking arround for some STI bits on tuesday, about the dump valve, dont you get chatter over the turbo blades when its meant to release the pressure?? When I bought mine it had no dump valve on it and the noise was awfull,

 

Hi Kev,

How did you get the later TPS to work. 4 pin to 3 pin?
