considering possibilities with a smaller turbo than the dom 3

[ndubz]

So I have a dom 3 sitting on my shelf right now and I do want to put it in my car, but with my money situation right now and the fact that my car is able to spin all 4 through second on wet or gravel roads and on dry roads to some degree as is, idk if this is the best time to be going for that type of power. I know i could just wait and save up and have the Dom 3 installed within 2 years from now, but because thats such a big timeline im considering other options too. I just want some advice from tuners and anyone else who knows.

So im thinking right now, when i was tuned my injectors were at 93% duty so they will need to be done no matter what direction I go. And I know the stock VF39 is limited, but I have seen them run up to around 350whp on certain setups. Im thinking id sell my dom 3 for around what I bought it for, and do like 740cc injectors w/ walbro 255, and run an external wastegate setup and an ebcs. and get a nice tune. Im not big on meth, and yes I know thats an option. And i would be willing to have the VF39 ported polished and coated.

Im just kicking things around right now. let me know what you think and what advice you have. Obviously I realize with this im not getting anywhere near 400whp. Id be shooting for 330whp or so, which I have seen done on pump gas before.

My current mods are, EL headers and the rest of the exhaust, perrin short intake, samco turbo inlet, Perrin TMIC w/ all piping.

If I may ask, what did the D3 cost? I picked up the new FP 68 HTA for a REALLY reasonable price from JSC Speed (and promptly popped my motor). LOL It was a combination of small things (bad plugs and severe blowby at the top of the list) and a really hot day on the dyno with much cooler weather a few days later that led to the detonation. NEW version EJ257 SB and CP pistons (along with a Crawford catch can and a few other goodies) is getting dropped in @ AREA 1320. Power is going to be perfect for what I'm looking for. I'd recomend talking to Aaron at JSC Speed about your plans and goals. DO A FUEL RAIL TOO! Good luck.

Hmm HTA 68, i was looking at that before, and might still consider it if I dont do the Dom 3. I got my Dom 3 used for 900, seems to be in good shape, it came off a running car that ben a rod.

I dont really see what the problem is... your not at a point where your cars going to have traction problems all the time on dry roads. Does it really matter for wet or gravel? Seriously... I'll spin till 8k in the vr4 and i have Awd and 8.5 inch wide tires on all four.


If your dom3 needs a rebuild (like I remember)... then pick up a FP green or any other turbo and do your fuel system.

[ndubz]

I really don't think it needs a rebuild. I said I was gonna have blouch inspect it to make sure it was good. And Im not that worried about wheelspin. It's mostly the money issue. But I honestly don't know if I really want 400whp. I might have more fun with 340-360

If you can barely afford to do your turbo swap atm, what are you going to do when your motor pops from trying to put down 400 whp? Can you afford to garage your car for a while or is it your daily driver? All important questions that should be answered before anyone can give you any advice.

[TalonTsi97]

you spin 2nd in the dry? Sure it isn't your clutch slipping?

You again???


Sell the turbo and use the money on porn site subscriptions.

Believe me, I've considered all scenarios. I have a plan if the motor pops. And no im not rushing this. I made this thread just cuz Im thinking about various options.

Positive, brand new act clutch and Ive driven many cars with clutch slip. if im going in a straight line it only chirps briefly, its when I turn and boost in 2nd that they all come loose mad easy. like I said, not really a huge problem, but I deff want to keep the car fun and NOT a hassle. ie i dont want to give it too much power. I had a god talk about this with Cleo at precision when he was tuning my car, he urged me to use caution with the power level. His sti has 589whp, he said its obviously insane, but he said as an overall drivers car, my car with 300whp was much more fun once uve gotten a few straightline blasts out the way. for the roads in my area, I dont think much more than 400whp would be necessary...or a good idea for that matter. Im not someone who is all about the highways, I use my "rally car" on rally like backroads and Love every second of it

If i was a little more knowledgeable about turbo upgrades on a subie it would help but from what it looks like your best bet is to sell the dom3 and either go with a slightly larger turbo then you have now or try and improve the setup your working with. A 30-350whp can be a lot more fun then a 500whp car but its all in the setup and what you intend on doing with it. If your just going around your town then there is no sense making your setup more complicated then it needs to be for more power that will be harder to use. If your planning to drag race then obviously use the dom3 and go for a lot of power. If your trying to do scca or road course then focusing on spool up, suspension will be your best bet.

yea, well put. I mean I dont drag it, I plan to maybe take it to the strip once or twice, but its my DD, a street car that I have alot of fun with on all sorts of roads. but i specifically love the twisty country/ wooded roads in my area and I dont want to ruin that fun by making it too powerful. Im just kicking stuff around right now. But it may be worth selling the Dom and going with other things because all the supporting mods cost more for a larger turbo. I may also keep it and install it eventually too, i just want to weigh my options.

[TalonTsi97]

If you can get the most money for the dom3 now then do it, you can always buy another and probably cheaper down the road if you really have to have one. Considering your rarely take it to the strip, don't do scca/road course there is no sense to really complicate the setup.
I'm not sure the specs on the turbo your running now but porting/coating, maybe ewg and more tuning will more cost effective and fun

Going fast is fun, but if you’re running into financial issues with the build, there is no way you can cover it when the motor goes. If I were in your situation, I’d put the power build on the back burner and start slowly upgrading your chassis/suspension.

That way, by the time you can swing the power build AND cover the expenses if it pops, your suspension will be able to better hold you down. I don’t know if you’re into it, but also take it to a few auto crosses.

if you cant afford to put it on the car, why did you buy it in the first place? given your track record with that car i cant say it surprises me that you make bad decisions.

cuz its a work in progress. I got the turbo cuz its the one I wanted at the time, ya I know i seem indecisive. The Idea was that having the dominator would give me some direction, cuz before I had no idea what to get. But I drove the car alot this summer going to and from school (like 25 miles each way on some good roads) and the car is so good right now, that I think I may rather go for mid 300s and keep it TMIC and not a huge ass turbo for the spool time. On back roads I dont really want to wait for boost too much. and I know the dom 3 isnt a laggy turbo for its size, but its still a good bit more than the VF. and thats great on the highway, but not as good for the twisty roads I love so much.

I know i seem very mixed right now, its cuz I am lol. But remember, im just kicking around options right now, Just seeking knowledge.

My question is how far can the VF-39 go? I want to go external wastegate, and I know that helps it hold more boost better, and I might port and polish the turbo if it would be beneficial enough.
