Got the car retuned after installing some S2s and snow performance water meth kit. Lowest horsepower pull is a very very conservative tune for 89 octane. I'm getting stationed overseas and 89 is the highest octane at the pump so I asked for a safe low boost tune. The green lines were when I had Comp 100s installed and no meth. Boost started to fall off on the top end from 30 to about 27-28 psi. I just purchased an evo 3 intake manifold so I need replace the stock 2g manifold.

Bolt-on Modifications:
8 blade Holset HX35 .55AR bolt on housing, Punishment Racing Tial MVS recirc o2 housing, FP exhaust manifold, FP Intake, RRE downpipe and Apexi mid pipe with Vibrant twin tip muffler, FIC 1050's, DW200 fuel pump, Greddy Type S, Hallman Pro RX boost controller, fuel lab fpr, ETS Street FMIC

Engine Management:
ECU flash, EvoScan, Autometer Boost Gauge, LC-1 wideband

Engine Internals:
Kiggly Beehive springs, GSC S2s, Wiseco 8.5:1 pistons, Manley stroker crank, Howard(MAP) rods
 
Nobody except my transmission. I'm hoping to get a little more out of her. Hopefully I can't get her over 450 with a ported Evo intake. I want to replace the stock 2g tb elbow as well.
 
Thanks man. I am enjoying it while my transmission allows me too. Hope the Evo3 intake manifold helps the top end a little. I think I'll eventually go with a 7blade with a twin scroll manifold.


That's exactly the route I would go. Make sure the tubing on the manifold is as big or smaller than 1.5"OD and that'll help spool. Helped put together a locals twin-scroll setup and when going from over 2"OD tubing manifold from a popular vendor to 1.30"OD piping it dropped spool drastically. Still put down very decent numbers as well. On a 2.0L, with an HX40 in the 16cm(or 17cm...forget which of the two) it was seeing spool as fast as his logs showed with his .55a/r bolt on housing, but power didn't drop off on the top end. His 70-90 times dropped drastically as well. Thoroughly put to rest any of doubts I may have had about the setup. So a twin-scroll HX35 7 blade on a 2.3 would spool retarded and make killer power. May not be as much as his setup since you're going conservative, but it'll be a lot better now. Spool will remain the same, but power won't drop off up top so drastically.

Keep me updated when/if you go twinscroll and how you like it. I love adding people to my list of "successful fast spool/great power twin-scroll setups". :D
 
It's just a matter of when. I would like a manifold similar to Mr. Peppers. I'm all about simplicity. His manifold doesn't look as sexy as what the vendors are selling but the thing performs and that's what matters to me. Something with a single wastegate. You think there is any chance of getting an hx40 to spool this fast in a twinscroll setup? Streetability is pretty important to me. That's the only reason I haven't really considered an Hx40.

Nice. Appreciate you choosing us for the beehives ;)
 
Thank you. The choice was obvious. When I change setups I'll be able to get more use out of them. I'm sure revving them to a little over 7000 rpm isn't even tapping into their potential.
 
80 meth/20 water. Im running the biggest nozzle that comes with the snow performance stage 2 kit. It's a 625 ml/min which is almost a 10 gph nozzle I believe.
