Default who knows anything about ver 1 sti stuff?

For those that know me from other boards, I'm also known as overspool. And for those that don't know me yet, I go to college at WSU and live in Phoenix during the summer. Anyway...

So nothing is official yet, except for the fact that I'm selling my 08 wrx. Insurance is killing me right now, among other things. But that's neither here nor there.

I'm possibly looking into picking up a car with a jdm ver 1 sti swap. It does not have the original transmission, but has an 04 or 05 wrx transmission in there now. It's running on a TD05H with an 06 (i think...) intercooler. The engine and drivetrain has around 50k on it.

Anyway, let me get to the point. If I do end up picking up this car, I am wondering if there is anybody in the UT area that is knowledgeable about this engine, etc in case I needed help or had questions on anything. Because the only car I know anything about is the 3rd gen wrx, and my knowledge at that is limited.

And before anyone asks, its not a Utah car.

Thanks RMIC!

what do you mean "knows about it" ??

subaru engines are mostly unchanged for the large majority of major components so Solid autoworks could service it for you. but are you more talking about what mods can be done and what kind of tuning sort of thing? because those things are more of a bag of worms depending on how the swap was done and exactly what mods are in it, at least from the tuning side.

EJ20G I believe.

azn2nr- there are differences between an sti block, a wrx block, a bugeye block, and a jdm sti block. I know a bit about the 08 wrx 2.5 block, but not much about any 2.0 blocks. To my understanding, there are quite a few big differences about the jdm sti engines. I just want to know if anybody has done any work on them, that way I know somebody can help me out if something goes wrong. I informally talked to Solid, they "can" work on it, but prefer to stay away from swaps like this.

the main difference is that the blocks are closed deck. beyond that, you need to get spesfic as to what you have questions on.

WRX and STi both had closed blocks up until mid 1994 production year.
At that point they all went to semi closed. Only one after that in the G series that stayed closed block was the RA models.

Easiest way to tell is to look at the block by the turbo. If you see cross hatch marks then it would be a good chance of being closed block.

And as stated many times before, the open and closed blocks both have the same weak point. That is where the block bolts pass next to the cylinder to hold the 2 halfs together. So no matter how strong 95% of the block is, if they both share the same weak point they both will fail in that location.

^^ This


Sounds like a great car. You do probably have the TD05 16g on it, and that newer intercooler is perfect. I love the old Subaru engines, they are easy to work on, run well on the 91 piss we get, and they don't seem to mind some abuse. I have had a handful ej20g swapped Imprezas and Kirill has had even more. Seems to be the best bang for the buck for a quick Subaru.

Stock coil packs are crappy and can easily be replaced with 02+ WRX coils. Many of the newer WRX performance pats bolt right onto the engine, and the engine does share many parts with all the other phase 1 (93-98) engines, and some with the newer WRX and STi.

Post some pics of the car if you can, hopefully you end up getting it. Let me know if you have any questions.
Thanks,
Rick

Rick is a hippy, he dont know


Also things that will need attention. Coil conversion is almost a must. The stock coils break often, and when they do replacements are hard to find and are only available as used.

Front and rear main seals leak if not replaced. So far every G motor I have ever seen has had one or the other leaking. New oil pump is also a must, as the stock ones seem to have the internal hardware back out.

Other then that. EJ20G FTW!

Awesome thanks guys. I don't want to post pictures yet, seeing as it'll be at least a month before I would be able to pick it up. It has a little trouble on startup, could that be because of the coil packs? Amd for some reason the stock injectors were replaced by smaller ones. The stock ones would come with it tho. If I do end up picking it up, I'll let you know rick or kirill. I'll need somebody to look it over and tell me what needs to be replaced but the current owner has done most of the maintenance.

Thanks guys!

Start up troubles are usually sticky IAC(idle air control valve). Seems like all of my engines had a sticky IAC, cleaning it will help, as will running a catch can.

Also if you do end up getting it, I have a OEM factory service manual in english if you need it.
