My car has been down for 2.5 months on full tank of E85. What's worse is injectors aren't in rail the entire time. Hopefully, I'll get it running by next week and burn up the E85 over the week.

I was naive to think I'd be up and running in 3 weeks. Lol

 

I know right, i guess ill have to do some kind of annual cleaning/inspection. Maybe ill pick up a spare set when they show up cheap in the classifieds so i can easily swap em out for cleaning.

 

I almost don't even bother trying to work on timetables anymore, as long as its not just sitting getting forgotten about.

 

I'm pretty torn on S1 vs S2 right now. Just for a little background I'm running the HKS GTII 7460r (OG w/o revised turbine housing). I was doing a best of 430/400 (VD) on E85 w/ the stock(intake, airbox w/ K&N dropin, intercooler, UICP ). I really liked where the car was at with power and transient response. This is my DD so area under the curve, response, cruising manners, and idle are all higher priority then peak performance. So where I am conflicted is, should I play to the strengths of the setup and get the smaller cams, or get bigger cams to try and help where the turbo wants to fall off. It's a small turbo so relatively speaking its going to spool pretty fast regardless. So with the goal of maximizing area under the curve, with the obvious higher rpm breathing disadvantages of using all those stock components, what would you do?

P.S. i know this is a beaten to death topic, but i thought my specific use case might merit some discussion.

 

S1's are probably similar to the cams you took out. S2's won't hurt low end or spool too much, but they will have a rough/lopey idle since you don't have mivec. Unless you make the car idle in open loop with a 13.5-14.0 AFR, that will smooth the idle a decent amount.

 

Are S2 available now? I have to wait over a month to get mine last Christmas. But mine has MIVEC.

 

GSC makes cams in batches, so they kind of have a cycle of in and out of stock.

 

Sounds like S2's are the way to go. While I'm at it do you think adjustable cam gears would be a worthwhile addition?

 

Not unless you're going to put the car on the dyno and play with them to pick up few HP's here, and a few tq's there.

 

The opposite, I was thinking about messing with them to try and improve idle by reducing overlap maybe. I just want to have my cake and eat it.

 

I wouldn't do that. Just going to hurt Performance. Get S1's if you're worried about idle.

 

My S1s did 430ish on an HTA71, I think, and almost 480 before running out of fuel, on an FP Green. I never found myself needing more power. However, I run relatively safe and conservative tunes so I don't have to worry during HPDE. My car idles like stock, from what I can tell. Also, mine are MIVEC cams so not sure if that's comparing apples to apples.

 

if you made 430whp with 71HTA and S1, I'd agree that your tune is safe since I made 430 with stock cams. Lol
I vote for S2

 

My car wouldn't live long at 430whp on stock parts.

 

Yes, I find the idle on my S2's hypnotic. Just love the lope /idle. (71HTA on MIVEC)

Would hope to see you turn the EvO into your 2nd weekend car. I could never DD the EvO & continue to enjoy it
