WRX and Porsche g50 help and parts list

[kai4130]

Hi, guessing your not that far from me then Mr low crime rate....high drug rate though in your hood

Have you already built this subaru engine yet? My JDM motor as standard is 260bhp, ditch the cat, better exhaust and intake modifications then get it remapped and you'll be into the 275-300BHP. That's on a standard engine, at £400 a motor I'm prepared to take the risk a couple of times before I shell out the big bucks for the race motor. The people I've taken out in my car have all said its an amazing sensation of speed when it's boosting hard, its not the same for me though, my daily driver is 540bhp, I'm used to acceleration. If I could get my 915 to shift quicker then I think that my Beamer and my notch would be well matched.

Also.... What engine you basing your build one??? What year? You mention v4 sti heads. The different phase engines have different stud patterns for the inlet manifold, the later engines don't have a MAF, also the IAC is in different positions too. I ask this as you don't want to be attempting to run a phase one ecu and wiring on a phase 2 engine with phase 1.5 heads and inlet manifold. Will be difficult to get it running.

Everybody I know that's done a conversion will tell you to buy a donar vehicle and not an incomplete engine.


RJES don't make a shallow sump to my knowledge, however you can easily modify the Subaru sump to raise the bottom of it to the level of the exhaust headers gaining 25-30mm and keep the same quantity of oil.


Good luck finding short nose G50. Knowing what I know now I wouldnt fit my 915 but I'd go for the Subaru gears route. Overall it would be cheaper and easier to install.

If you for Kennedy adaptor, when you buy it tell them you want a clutch and they can supply you with one.


Too many questions to answer

Hi mate thanks for the pointers.

Oh and the crime rates not too bad here just need to bolt everything to the fooking floor, I have put some large ornamental planters on my mums drive and I have literally bolted them into the concrete to stop em being half inched .thats London.

Ayway I here what your saying re the jdm engines but I dont want to be pulling engines in and out on a regular basis as I have to pay someone to do it. I am trying to get something built good and strong to fit, forget and then abuse.300-350 bhp with the option to increase at a later date.Whats ya views on the fact that the reverse cut option has not had much real world use/abuse and if I needed to replace the gear in the distant future and the bloke is no longer making them I will be back to square one.I think the engine will be based around a phase 1 block 1993-1995 not sure 100 % but need to talk to the engine builder to sort final spec.I am confident he will get it all sorted for me he has a good reputation and is well known in the Subaru rally scene.

I hear what your saying abot buying a complete car but I will be building a new loom fo it so fingers crossed it should all work out.

Your beamer sounds like a laugh 540 bhp, and is it you who has the blue notch ? oh and whre ya based in mate London.

Yeah I know London, tis a **** hole!!!! I work up there most days, but only when only when I have too. However I live just out side Guildford, and the beamer makes light work out of the commute. I discovered yesterday that it its actually 544BHP

Dont get me wrong about you building an engine, if you've got the readies spare then why not. I just personally think you may be underestimating these Subaru EJ engines. I'm actually on my second engine but since I've discovered that the old one was fine so now I have a spare engine But the price comparison between a built motor and used second hand engine says a lot. built motor I'm guessing is +4K, were as a complete used engine is £400. Thats 10 used engines, if your going through that many engines then there is something not right with the install

Either way, as a starting point I'm happy with the amount of power my engines producing and trust me it'll be a very very long time before I'm confident to drive the VW any where near as hard as I do My BMW.


Pulling a Subaru motor from a VW Chassis is no different to pulling the VW OE engine from the same VW chassis, its a days work easy.



With the Reverse cut gears, TTriebler was done some serious R&D on this stuff before he released it, I think He's been doing it for over 4 years by now. I can recall his early days when he was just starting it. I would have gone that way myself but at the time the stuff wasn't available. I could be wrong in saying this but the company that makes the parts for him I'm sure have been making this type of stuff for decades and are a well established company.

Also my experience in failed diffs all comes under my 4X4, usually with a failed halfshaft snapping and then munching the diff internals, even then with loose bits of metal in the diff oil I've not seen the Diff ring gear or pinion gear damaged. The only damage I've seen to a ring gear is the pinion gear support bearing failing, and being left unattended resulting in massive damage to the diff ring gear and pinion gear. I know I'm talking axle Diffs here but they are the same princible to what the Subaru gears stuff does. My point is I personally dont think you'll find trouble with the Subaru gears supplied kit failing itself, the problems will be a result of who ever installed them and how well they've done it. Even then I imagine you'll just rebuld the transmission reusing the Subaru gears stuff. Also I think this is a much more cost effective solution compared to the porsche route. All the porsche components are big money from what I recall, especially at a 20 year old G50 unit fetching over £1500- £2000. For that money alone you could buy a subaru donar car, break it for parts required and sell the left overs and make your money back. Thats what I did


I'm really pleased with my phase 1 set up, if your interested I have a spare phase one modified loom and Z4 ECU (1995 JDM ECU for the WRX), save you from building one from scratch. Probably a number of other interesting goodies too


Yes thats my blue Notch, and before you ask I've fixed the color of the wing mirros





And finally, if your in need of a reputable Mechanic I can certainly vouch for mine as he helped me with my install and has done a number of interesting VW projects.
