Re: Westfalia/Subaru STi question


 

I have a STi Version 2 (JDM EJ20T) engine rated at 278hp in a Syncro Westy. With my air/water intercooler & exhaust setup it is probably a bit closer to 300hp.



The van has been running great since 2005 when I first did the conversion, although recently I had to pull the transaxle since my throwout bearing (prematurely) went out :(

Daryl at AA Transaxle rebuilt & upgraded my transaxle when I first did the engine swap with taller gears, improved gear carrier housing, and some other stuff (can't remember). So far the transaxle has held up well.

There is lots of info on my forum that pertains to putting a turbo engine in a Syncro Westy that may help you.

Good Luck,
Kevin Frank
(it's been a very longtime since I've posted to this group, yes I'm still around, and loving my van!)

Hi Scott,

Let me clarify a bit more because I'm not sure you saw all of the renditions of this post. I have a Westfalia Syncro and although, yes there are lots of turbo 2.5L (Ej255) engines installed into both normal Vanagons (like in the link you've provided) and 2wd Westys but in a Syncro Westy there has yet to be a 2.5L STi (Ej 257) engine installed. I have heard of one being installed into a Tristar (Eric) but other then that no, I have not heard of one being installed into a Syncro Westfalia camper van. These models have a number of difficulties which are not encountered in the 2wd model or in a regular Vanagon. Please, If I'm wrong show me an example of one that has been done and I'll be a very happy man because I'll have someone to guide me in doing the installation. The link that you've shown is a 2.0l turbo being installed into a Vanagon ... apples and oranges. The difference between a EJ 255 and an EJ 257 is about a 100hp.

Hi Dean,

Thank you so much for your response! I really respect your opinion. I've done a lot of looking around and think that you are quite right about the whole power issue with regards to the Westy really not needing to have an STi engine in it. I must admit that one of the reasons that I'm doing this is to see if it can be done. I enjoy the challenge the project poses. If I could go back and start all over again I would probably look into a WRX engine instead but I would still be running into the same issues, more or less, then with this one. I think at this point I may just tune back the engine once it's in there and treat this as more of a research project then anything else. The nice thing about finishing this all up with the engine that I have now, swapping it out later with something a bit more reasonable will be a very easy undertaking and I would be able to sell the STi engine for much more then what it would take to buy and new engine. That, however is not the plan, only a worse case scenario.

Best Regards,

Mike

Seems like you are going to end up with a HotRodWesty that, unless you happen to be a bizillionair, you will be camping in on a piece of ground that has a gas station on one side & an autoparts store on the other.

Not so much the cost of the ring and pinion set but I need to get a transmission, a front diff, new drive shaft, new drive lines for the front, etc. The work needed to be done is pretty crazy too. The Sub transmission, I believe is a bit too long so crossmembers will have to be altered. The output shaft on the Sub tranny is on the top where the output shaft on the VW is on the bottom so I suspect there are going to be issues with the driveshaft with respect to the undercarrage. The estimate was fairly generous at 6000 though but for a 4wd, I'm not sure the cost is worth it. I may consider changing the 4wd to 2wd and eliminating the whole front end issue because realistically, I have never been in any situation where I may have needed it ... Currently the front diff isn't even hooked up. If I was to change it to 2wd I may reconsider but I have not run the economics on it as of yet and I would more then likely compare it to the 2wd Porsche option. Of course there are other factors, other then cost and ease of instalation that need to be considered. I do like the Subaru option as I also now own a STi but I'm not sure if it's going to be the best fit for this application. With that said I really like your reversed ring and pinion design and the flange that'll work with the stock cv shafts. It'll still be reconsidered if I decide to convert to 2wd.

Customer feedback on the Subarugears product and pricing is valuable to me so I wonder if you could give me an idea of the decision making process on a Subie 5 speed vs the work you are having done on your existing trans.

I did look into Subarugears option but after all is said and done it'll cost close to 6 grand to install it and thats doing all the work myself. Not to mention the undercarriage alterations to get it to fit. Currently the best option I've been able to come up with is to rebuild the tranny with 3rd and 4th racing gears, install new splash plates and some reinforcing plate and nuts to prevent both slippage and flex when the unit is under load. Not to mention all new syncros, etc ... After that is done it should hold a bit more torque then a stock unit. I've heard of people putting a wrx engine in with a stock used tranny without any issues. They are even using NA clutches which I would have thought would let go under that strain.
