Ok so ive found the issue, the restrictor pill was in the wrong place, found a diagram of how it should be and now its way more responsive, goes straight to full boost at 3.7k rpm instead of 6k rpm! way happier with it now! also found my ecu is a j2 which from what ive found out is from a V6 WRX STI RA Limited. Cheers for all of the info everyone gave me!

You know at this point I'm not going to exclude them having done something deeply stupid like using the factory black box of doom for boost control.
I bet two internet cents it's an EJ208 in the middle too.
What's the ECU? If it's running all the EJ208 heads and manifold then it's probably running that sensor setup with that ECU.
To be honest it sounds like the "V7 STI" swap was actually a really average single turbo conversion.
believe it or not it is definitely a ej207 block and internals, thats the one thing the guy provided photo proof and receipts for and as far as i know its a v6 STI ecu so its all over the bloody place

How does the boost control set up look? Wonder if half of the weird ass Legacy TT bits are still in there messing things up
could that be making it so its boosting in 2 stages like the factory TT does?

For diagnosis pull the waste gate hose off, clamp it. Go for a drive and floor it, keep an eye on the boost gauge, note what rpm it hits 14psi and let off the gas.
If it's still "laggy" and at 5k then it's likely a mechanical fault (turbo, exhaust leak, boost leak etc.). No form of boost control will fix those issues.
If it comes on boost earlier then fault is likely within the boost control system or ecu. If it's this, fix the fault rather than patch it by adding boost control.
by wastegate hose do you mean the vacuum line connected to the actuator or the turbo? Cheers

so i done some looking around under the bonnet and found a bunch of s*** not right.... so i didnt do the engine swap and after some research and looking under the bonnet i found that block and internals are v7 sti (ej207) BUT from my understanding the intake manifold and the heads are still the legacy (ej208) heads and intake mani. the turbo is also a td05 16g so what ive found is the guy i bought it off was bulls***ting the whole time saying it was a "full v7 sti swap" so im f***ed of what to do, do i get a link ecu and get a tune OR do i "complete" the swap and make it v7 sti everything like it should be. Cheers

Has anyone ever put a V7 STI dash into a 3RD gen B4 Legacy? wanting to do a full dash swap maybe even a full V7 STI interior swap into my B4
Cheers

solenoid is a factory one and yes restrictor pill is still there, i believe its a 1.2mm

ive been thinking of adding a boost tap in. or should i just go external wastegate with a 15psi spring in it and run wastegate pressure so ill just consistantly get 15 psi

Hello everyone
im wanting to know why my turbo is so damn laggy. i have a feeling it could be the boost solenoid. i have a v7 sti motor in my B4 legacy and it runs mint apart from this annoying lag, turbo spools to 7 psi and sits there until about 5k rpm then it finally hits full boost at 14.5psi. everything is factory v7 sti (engine, loom ecu) so its not like a aftermarket ecu without a tune or something.
im wanting to know if i should disconnect the boost solenoid and run wastegate pressure.
Cheers

CheersTechnically yes it needs a cert. Realistically how many wof issuers would notice? Not many unless they know Subarus well
true true, only thing is theres alot of very clear aftermarket mods but i mean who knows maybe they wont think anything of it

I reckon it will be & you'll be fine
its around 250kw atw so idk if thats within the threshold or not

Just google the potential gearbox code. If the final ratios match then no need. If it’s different then getting the right matching diff would be wise

Easy as then. You only need the gearbox. You don’t need the driveshaft and diff
Sent from my iPhone using Tapatalkwhat about the ratios, doesnt it need to be matching to the diff?

old box blew 3rd gear and syncros are stuffed in 4th

Hidy ho,
The answer is yes it should fit indeed. Did you blow up your old box or manual swapping?

Hi people. Im new to this forum and was just wondering, will a full manual kit (gearbox, diff, driveshaft, etc) from a bh5 legacy fit into a be5 legacy?
Cheers!🙂

Mute gauge
in General Vehicle Discussion
Posted
Hi all
ive installed a prosport wideband AFR and man that thing beeps loud on start up. i know how to mute the gauge normally using key in ignition but my gauge is hooked upto a switch. would i do it the same way as i would with the key in the ignition?
cheers
