Just bought my Ralliart a couple weeks ago after my Golf was totalled. I'm really liking it so far but I miss being Turbo'd. I've read that the 4g63t head will bolt onto the 4g69 block we have. But I cannot find anything on the forums about that. Any insight is much appreciated.

 

Its possible. And has been done by a member named mitsuorder. Also believe I've heard of a few people on club4g that have done it too. Problem is the wiring and ECU.

If your just missing boost though you don't need to swap the head. There are members that run boost up to 14psi on a stock head and stock internals. And you can use piping, turbos, intercoolers, and a lot of parts from Evos to get your kit started. Lots of info on it all here.

Welcome to the forums!

 

Okay, since posting this I've been reading cranswicks turbo build thread, and about halfway through. There is a lot of info in there, but it seems most the build was from years ago, will much have changed or are there more fabricated parts since then? besides the 4k RRM kit, I am hoping to stay down around 2k.

 

There is a fabricated exhaust manifold now. But its still cheaper to have your own built. Dont even take another look at the RRM kit. Its overpriced and not built well. Instead of uping the size of the factory injectors they opted to add a fifth injector pre-throttle body, and the tuning for it has bugs as well. I think Cranswick spent 2k or less on his build. And on my build I saved myself a lot of work by picking up used evo charge pipes and intercooler. Surprisingly it all bolts in, with the exception of one place on the cold side pipe. As far as tuning everything we have two methods to do that now. MMC/EcuFlash, member OttRalliart can get you going with that. Or Fastworks, member Hackish is in charge of that one.

 

what's changed?


since the initial build, I've gone to a bigger turbo, and added a manual boost controller...but I think I updated the build thread with those items...so nothing...just more boost. the costs of everything should have been updated a few times throughout the thread...I think it was about $2,000-ish including dyno tuning. I don't think I accounted for the clutch in the cost...but given that I only paid $150 for a new in box ACT stage1, it makes little difference...

 

This is going to be my first turbo build, (my brother in law is a diesel mechanic and will be helping) so I am going to take it slow and do it right. I am wondering if I can do it in several steps though. Can I run the larger injectors then a tune, while I mock up and weld the exhaust manifold/piping. Then turbo and retune? it seems from the few full build threads I've found people do it in one shot. Also, It seems my grocery list will be

- Exhaust Manifold (manufactured) -$300
- 3 bar -$100
- External wastegate (optional)
- BOV -$250
- oil and coolant lines -$100
- Tactrix 2.0 cable - $180
- Boost, A/F, EGT guages and pods -$ 200
- tune from hackish or ottralliart -$500?
- 16g Big Turbo - $680
- WRX 440cc fuel injectors - $130 (used)
- Piping from an EVO 8 plus work ~ $300
Total~$ 2740


Let me know if I am way over simplifying this, I want to know exactly what it is I am getting myself into before I start.

 

no need to run the larger injectors in the interim, as they take literally 10 minutes to change, so you're best off, just having them on hand for install day, plus you don't have to **** around scaling them for non-turbo daily driving...same goes for the MAP sensor...

 

Yea there's no need to install the MAP or Injectors first. I thought about that too but it'll be simpler to drop them in and let the tuner do the magic when the boost is there to properly accommodate the added fuel.

Might want to add some gauges to that list. You'll need a Tactrix 2.0 cable for either tune method so you can go ahead and add that to the list as well.

 

Anything to change on here? Better prices, missed something, anything unnecessary?

 

clutch...


also $250 for a BOV is pretty steep...If you want a brand name BOV, get a used one...just get a stocker from an Evo, or DSM. if you want a fancy one, you can get them on here in the for sale section...you could probably find one with little to no wear for much less...


it hurts me to see used 440's going for that price...I got mine for $40 with the pump, and I only had to drive 40 mins to get it...but if that's the going rate, it's just another one of those things...


is that turbo new? again stock Evo or DSM turbos will work also...I paid $50 for my 14b, which I made 213whp with...and later I paid $250 for my big 16g, which is still running strong...

 

did not think of that. and the clutch was just replaced a couple thousand miles ago by the previous owner. hopefully I can sell it If I drive carefully.

I put this list together real quick, so I didn't do any price comparing or any real search for anything cheaper, but that is good to know if I look there is much cheaper to be had.

I believe it was refurbished, but I have a pretty trusted turbo shop near me so the final plan is to get a used one and have them rebuild it.

 

it's a good start...for the clutch, you WILL need a stage 1 minimum...

 

Our tune is only $250usd if you do not want the expense of buying mmcflash I can rent one to you untill the tuning is complete, in the end the tune is only $250.

 

mmcflash is the software right? The advantage of actually buying it would be I could make changes down the road myself?

 

Yes, you can buy one for sure. I rent them to keep the cost down. Eventually ecuflash will fix the write issue. It would be a sore point if you buy mmcflash and then ecuflash fixes the issues, you spent that cash for nothing, that is one of the reasons i rent them. MMCFLASH is a great program I have been using for some time with no issues.

You will still need a XML definition both mmcflash and ecuflash will only read and write to the ecu. ECUFLASH is the editor but without a XML definition you have data and thats about it. I can provide a XML definition thats the easy part.
