Advice on new setup for 1.8 swap
 
I cooked my motor last night after a coolant line burst. I have a low mileage 1.8 to put in, so I am looking for a new turbo setup. I want something that is not laggy and I am not looking to be the guy with the most power, I just like a car that is fun to drive. What is everyone's opinion on what manifold/downpipe/turbo I should go with. The cheaper the better, but I'm not into fabricating much, so it needs to be something I can purchase.

i am really starting to like BEGi stuff
i would be looking for used stuff though, but i would only buy a used turbo from someone on this forum (well not everyone) you get the point
lots of good deals here

I agree with cheaper is better, but I also only like doing stuff once.
My 1.8 setup is going to be the BEGi S5 T3 mani w/ a tial 38mm external wg. If you want insta-spool® just add a T3-S60.

But so many deals can be had with all those JDM nissan bois :gay:

Case in point... I just snagged a T25 with 20k miles on it for $77 shipped cause the girl just needed to get rid of it. From the pictures it looked great, but we'll see when it gets here...

That is the way I'm leaning right now, but I am trying to decide how much I can get for my current setup and how much more I want to spend.

What's the diff with the S60 and regular T3? What size injectors would be appropriate to run with the T3? I ask as I have RC 550s right now with the Hydra. Thanks.

Zabac 10-26-2007 02:19 PM

550are good...i think the S60 is just fancy name for its trim level since it is very popular in a lot of different applications
its still a T3

So, I think I am pretty set on the BEGi S5 setup with a divorced wastegate, but still not sure on the turbo. The T3 Super 60 looks nice, but I am concerned about how much power I can make with it. My Greddy setup was in the 225 whp range at 12 psi and I had full boost around 3400 rpm. What would be capable with the T3 Super 60? I don't want to drop a 1.8 and see only minimal gains or even worse, a loss in performance. I would like to see at least 275 whp (300 whp would be better) and be in the 12's on a quarter with the new setup with minimal lag. Is there another turbo that would suit me better?

Zabac 10-31-2007 02:47 PM

not an expert, but im sure the super 60 will get you to the high 200's easily while still spooling fast

Not knocking the BEGi stuff as I have their mani/DP, but you might want to also take a look at the ETD Racing shorty tubular manifold if you have someone around that can make you a DP.

Also from the compressor maps, the T3 super 60 fits somewhere between the GT2560 (FM's turbo of choice) and GT2860 (aka disco potato) so should be right in your power ballpark.

I've been thrilled with my BEGI manifold/DP and a GT2554R. Smaller than a T3S60, so it will spool faster and peak earlier. For someone who is looking for quick spool and fun around town/on an autocross course, the 2554 is the ticket.

EWG is, IMO, unnecessary unless you intend to run a decent-sized turbo like a Potato or a 2871 or larger.

Don't forget anti-lag + launch control. Its the only way.

T3 S 60
Nissan T25
GT2554/2560
Old Saab Turbos
