I may be wrong but don't quite a lot of tuners lock the ECU's?
Just had my car tuned at EnH and happy as with the result and they a good folk to deal with.
Not in my experience to be honest, car has been tuned by:
GCP
DTech
HItech
None of these locked the ecu.

Haven't heard of them, dont mind travelling if tuner is worth it.

It probably wont get there on 98.
Maybe I need to just keep the flexi fuel and go g30 . Nice video , haven't seen that before dont think i would use pbms was going e and h but the fact they lock the ecus after tuning has stopped me.pickimg them too.
340 kwatw is good just wished he stated boost pressure. As mine is not a daily i should probably stick to g30 770. Need to find tuner now.

If you interested in what the G25 or G30 will do, then Speed Academy has a through video on it with their STI.
Links here:
They then upgrade to the G30-660
But before most of that, they have a direct comparison on the dyno with another GTX3071R
Thanks some good videos. I am leaning towards going g25 660 as I want better response. The last video is with a gen 2 version of my turbo, I only have the gen 1 turbo so perhaps this would give me what I want on 98 Ron and same boost. Seems g30 660 definitly would.
I'm not that bothered about higher hp up top, more interested in response. 400wkw is quick enough really. Just unsure if the g25 will get there on 98 and not the e85 I needed on the old 3071 turbo.

Haven't been on here for a few years but I'm out of touch of the current turbos on offer.
I'm looking to get the car retuned, remove flexi fuel and upgrade turbo but I would like to hit same power on 98 with new turbo as the setup with e85.
The car has had everything modified on it, the short block is built to take 1000hp but I only run it at 405kwatw on e85 30psi boost on the very first gen gtx3071 r turbo with 0.63 ex housing.
I want to replicate these numbers but with a new generation turbo which should give at least 20% power increase over current turbo but been out of touch so interested what the beat choice would be these days, I'm leaning towards g30 660 or 770 options but open to all turbo types. Even thinking gt25 would suit. I Got no interest in Steve murch turbos so discount him.
Help would be appreciated. Txs

@Username where did you get the tappets from?
@Dairusire that was an option until the below. Twice the price and brand new crank with zero wear.OEM EJ20 nitrated crank shipped with customs is NZD$520 same as C-spec
https://partsouq.com/en/search/search?q=12200AA390$403 shipped to NZ
https://www.customs.govt.nz/personal/duty-and-gst/whats-my-duty-estimator/give $117
FYI...
2.5L nitrated and salt bathedI bought from kelford, they are described as 6 degree radius beadlocks, there were 11 bucks each not inc gst. Will be more now as all the other things I bought were, this was a year ago. They are far bigger than OEM.
I bought the same crank for mine too mo brainer , cheap really considering it's OEM.
Wish u could just insert pics in these posts the link to url is a pain in the ass.

So wow the Wiseco Boostline rods look amazing, very happy with them. 607.0-607.5 grams
I should get some photos up with all the other parts at some stage.
If anyone is good with video work I thought about getting all the sweet parts together to video and review.
Pretty much going factory crank now with info from the 500kw topic.
sounds like I need to go beehive springs due to the higher rpm limit I want so will sell off the titanium retainers I already have.I bought kelfords beehive springs, larger tappets, their valves and cams. Put these in my car and it didn't make a huge difference to power levels around extra 10wkw. I did have reprofiled cams before though through Franklin so didn't expect too much.
Getting the larger tappets In which hold the springs in on the valves is a bloody hard job, they are around 50% bigger than th OEM part. I've built my own heads a number of times now and these are way harder to assemble but are worth it as they are far better at holding the valve, spring etc in place, reccomend them.
I line bored my crank too and has extra dowels In there to help hold it together.

Gettint rid of my daily forester 97, manual turbo. 225k. Is it best I just list as a dollar reserve on trade me. Car needs Cambelt change, new oil pump, hardline coolant hose from turbo to header tank, and gearbox bushings.
Not going to lie about condition of car just want best price.
Should I consider Turner's or scrap yards? Or go trade me as u wont beat the price on there?

@Username i think the tuners not going over 25 psi thing is due to factory 2 bar map sensors. Cant run any higher unless you get a bigger map sensor
Good call on normal cars but mine has a 5 bar upgrade and aftermarket ecu, I was always told it's not safe above 25psi on 98. You are on water/meth which may give a bit of security, I don't know much about water meth setups.

Need bigger rear turbo housing I say. Subaru's do not like back pressure
I only have 0.63 turbo housing on my car and got decent power, but I agree would be a lot easier to make power with 0.82 housing just have to way up the lag aspect.

I put money on the fact the 272 Cams if from Franklin are not what they say they are if regrinds. probably stock lift. I got rid of mine as they were called very mild as I had them checked by kelford, mine supposed to be 276 but weren't and basically lift was left stock.
How much porting on ur heads? I don't understand why everyone praises v3 heads, I've seen them next to other heads v6 etc and there is no difference in port size, I don't get it. Late model Legacy heads 2004 ish are far bigger ports from factory and when ported more flow a lot more than v3 ever would. I would have thought u hit a higher number than that, one thing that worries me though is that no tuning shop I have used would go above 25 psi on 98 fuel as its too much of a risk.

@Username just curious to know. What headers did you use to achieve this power level? Stock or aftermarket? @gotasuby appears to have got near the 400kw mark on OEM legacy headers which is dam impressive!
I'm hoping to achieve 350kw off the single scroll OEM headers / upipe into a rotated setup on my v11. Pipe ID is 38mm from memory so hopefully will be the ideal mix of good air flow and velocity!
Aftermarket equal length bought from a rally car in Christchurch, custom made down there by engineering shop but nothing special really 1.5 inch runners I believe, 4-1 style 2.5 inch up-pipe. I have been told to buy a late model legacy twinscroll headers they are cheap and great upgrade for twinscroll setup, I'm still single scroll. Racefab quoted me 3k for headers only, twin scroll type, so didn't bother. I don't think the OEM setup u going for will restrict it that much so depending on turbo can't see why u can't hit ur number.
7 hours ago, pl0x said:Also what inter cooler size and what brand and AR exhaust housing?
Intercooler and radiator is just cheap type from redline performance still use OEM fans and shroud never had overheating issues, and exhaust is 0.63, yep its a big limiter on power maybe. Who tuned ur car?

In case anyone cares the stuff at gull e85 is only registering as e60 now, no where near 85%.

I've uploaded the dyno chart, only difference between this tune and old tune is head work and a better way of tuning the car for the flexi fuel setup I run. More porting done by Danspeed, to the extent the exhaust side chambers of the heads are like mirrors and that's no exaggeration. I changed cams to have less duration but 1mm more lift on exhaust and intake. Duration changed from 277 reground cams to 268 billet cams. Heads use standard size ferrera iconel valves on exhaust and standard ferrera vales intake with their keepers (far bigger than stock), beehive valves, titanium retainers etc, brass valve guides and shimless buckets. Marsh motorsport 5 angle grind on valve seats.
So if you want to know the difference heads make to an already powerful'ish car this shows it. Obviously my old heads had some work done to them and weren't stock but not to the extent these have been built now. Biggest gains are in torque though, I would need to go bigger turbo if I want more hp but waiting on the g series garrett to come out at the size I want, but I will be reducing boost on that and not really going for more power, unless of course someone comes and beats this then maybe I will.

Only way would to have someone with a FlexFuel sensor run some, and then pop up the laptop, and see what the sensor reads.
Or lab test it.
I'd also be curious to know if the E85 that Gull sells at a few stations varies in Ethanol content like it does in America through the seasons.
They drop the ethanol content in winter usually to get around the difficulty in starting the car in colder conditions. So add 30% 98 instead of the usual 15%.
I've seen this on my dash which gives ethanol percentage of fuel.

Yeah metal bits from porting, and also got new valve guides and valve seats cut. I got the right head plugs out with allen key but the left head is not having a bar of it. May have to drill them.
-
Has anyone removed the oil gallery plugs on Subaru heads. I just had work done and they are full of S***. Really want to be sure everything is clean so want to remove plugs to get in galleries and be 100% they are clean.
Also, can you buy new oil gallery plugs from Subaru? In case drill out is only option

Sinco are not the be all, I've seen some things they've done on evo's and its crap, like brand new headers warpped before fitting and they didn't give a S***.

Redline radiator using both factory fans on there, never had an issue with water Temp, never seen it move from 90. Had many other problems but not coolant related.

Aftermarket turbo choice
in General Vehicle Discussion
Posted
I was hoping for some feedback on these as I know nothing about them they are more expensive aren't they? Block was built to handle 1000hp.
I'm in no rush and sounds great txs. My car has sat in the shed on stands for 18 months another few wont hurt. Only concern is u have 2.5 L mine is basically 2.1. Who is building yours and running it. Are u worried about getting e85 now?
How did u establish it's the best turbo for spool up? Going to stick twisted setup for now too much work relocating to fog light cover area is what I think your basically saying.
