Well I am going to get that turbo, I just cant pass up a deal like I am getting, I have read a couple of articles coupled with some F1 racing info and it seems that used a similar idea as to the one I am using. Larger turbine house with small exhuast A/R. I guess we will see what it brings. I will not have this done before winter so prepare to wait for awhile.

 

good luck! how much are you getting the turbo for, if you mind me asking!?

 

$300 Brand new with a 3 inch downpipe and vband

 

what downpipe are they giving? for that price you could get a larger exhaust housing and throw that thing on too!

 

I can't imagine that it was just the A/R that caused those numbers.

I'm running a 0.48 A/R and I hit 400...

 

Exactly and it's been tested and concluded that even a .63 A/R turbine is pooping out at the top but is better for more midrange on this engine. The best A/R on this car because of it's high rpm is the .82 but it all comes down to what you want the maximum gains to be at; midrange or top end.

 

That all has to do with your manifold though. I have a .63ar hotside and I make 400 at 11 psi. If I was running 18 like you, I'd be well over 500 even with the smaller hotside.

To the OP, that is a great deal, you should go with a tubular manifold setup and I'm sure your car will be kick ass.

The cool part about having a midrange car is that you don't HAVE to redline to get the power out of the car. I don't even get traction until 3rd gear and I usually shift at 5500 rpms in 1st and 2nd. Having a huge midrange is like giving the car a V8. If you only want a 300rwhp setup, you shouldn't shoot for 300 peak, shoot for 400 and then you can have your 300 at 5k rpms or something and you don't have to wind the car out to redline all the time just to make power.

Don't mind these small hotside/turbo haters, they're just mad that they only make more power than us after 8k

 

I believe the downpipe is a custom job. I can get a custom tubular manifold made from stainless from a company here in cincy for pretty cheap. I am not looking to get huge number I just want a mild setup and right now it looks like I will be able to do this using very quality parts, using a v-setup like the guy on here, and an EMS or some other management system for under $4000 due to some of the friends I have here. This includes everything that I would need including tuning and a clutch. I know that there are a lot of hidden costs but I think this should be an Okay setup. Soul Coughing, yeah I was thinking of changing the exhaust side too for the money that I am getting this for.

 

The downpipe was a custom job. Unless you've got a T3 exhaust casting running my old tubular manifold for a Saturn, it won't do anything besides give you a free 3" V band clamp and a new piece of 3" flexpipe. If it's worth it to try to save, there's an O2 bung that you might be able to pop out of there as well.

I'm trying to make space, so the more stuff I can get rid of, the better.

 

To continue on, I am looking at a manifold like this for my application and I have recently been searching and accumulating information about turbos. I read that if you run high boost, you actually want to have a smaller wastegate to hold boost and vice versa. I am just looking for some direction on where to go. See link below for the manifold that I think I am going to get made by a local fabricator here in Cincinnati (good work).
