Re: Twin Turbo EG33 Build - cozykat
any updates? since my headgasket im planning to rebuild the whole engine and install a tt setup on my svx too. i heard that stock engine can hold up to 400 to 500 hp. is that true or just bs? my plan is to get from 430 to 450 hp to the engine.

Your priced menu does not seem to include any figures or items for charge cooling. Yet you are talking to Tom about water flanges. Does this mean you are planning to use a water or water/alcohol injection system? Without some cooling system, the whole thing will not work. Merely reducing the CR to 9:1 will not be sufficient to avoid the sort of problems Tom got with the Stage 111 install with detonation and timing getting hauled back. I flagged this problem way, way back in 05/06 and so it proved to pass. Also I'm inclined to agree with Michael, you would be better going for 8.5:1 or lower. This build is now a different engine than the NA motor, so you should be optimising for forced induction. Remember that you are boring out the cylinders, and the flat 6 has different low down torque characteristics than the 4 cylinder cars the Sti guys are used to, so you should be much less fearful of lack of pulling power off boost. You have probably already ordered the pistons, but IMHO you would be better with going to at least 8.5. Looking forward to your progress report Joe

Re: Twin Turbo EG33 Build - cozykat
Thanks Tom. Good to hear yours is working well now. {I like your new spider too. Or tick }
My main point was with no figures or cost for charge cooling, I think she will be limited in what boost will work. In which case the cost of the build will not be rewarded with what power can be achieved. Not without some form of cooling. Some of the more recent turbo Subaru EJ20 engines are using 9 CR and higher, but they have the flexibility of variable valve timing to change power parameters, [plus they all have charge coolers]. The EG33 does not have this benefit. Also the more modern engines are delivering relatively conservative horsepower, more conservative than the 97-00 engines. This is because they are now tuned to give clean emissions to match new and future directives. I'm assuming Marissa will not be restrained by emissions concerns, and that she would be looking for good hp and torque figures in return for her investment. Joe

Re: Twin Turbo EG33 Build - cozykat
Well Joe, quite frankly I would call her a fool if she did not add an intercooler into her system. That being said, she is no fool and neither are the other people involved in the development of her engine. I had the pleasure of meeting some of them at Reading this year. So I can only imagine that she simply did not add it in yet.

Re: Twin Turbo EG33 Build - cozykat
Yeah, that's the way I'm reading it too.
I can't resist this, and there's only one way to say it, so I'm saying it: COOLING IS AWESOME!!!

Re: Twin Turbo EG33 Build - cozykat
color my interest piqued.
I've wanted to put an EG33 into a mid-engined chassis with twin external wastegate turbos and twin intercoolers, Ferrari 288 GTO style... in a car that looks like a hybrid between the 288 GTO and McLaren F1. Window-in-a-window and a couple of other SVX allusions included. For the front engined SVX, a dual-core FMIC would be almost the only way it would work. Where would one even put two, or one large TMIC under the hood? Last edited by BoxerFanatic; 05-08-2009 at 08:14 PM. |

You could be like Tom and cut a huge hole in your hood.

Re: Twin Turbo EG33 Build - cozykat
Concerning cooling;
I don't think I gave her the current spreadsheet with the cooling parts list and numbers at the time of her posting prices. To keep it simple, the system will (should) rely upon an air to water intercooler that will take input air from each side and allow for a single (well twin t.b.) exit up top. Using the psychometric chart at work I figure that cooling moderate boost levels at around 600cfm should fit under the stock hood to avoid butchering the stock lines of the car. she is (I think) still kind of interested in a FMIC setup. I don't like the idea of increased volume on the compressor side of the intake as it just increased lag and makes pluming more extensive. Plus if you hack the bumper (and of coarse the bumper beam) up to fit in a decent sized FMIC, your insurance company won't like you much. p.s. pics of internals will be posted in a few days

Re: Twin Turbo EG33 Build - cozykat
Does the Stevesby bumper allow for fitment of an intercooler since it has a bigger opening?

Re: Twin Turbo EG33 Build - cozykat
I was under the impression that those bumpers weren't really that available. If they can be had, then they would look great with a FMIC stuffed in there.

Got the pistons today! (edited to remove stupidity)
here are a couple of pics anyway:
