Couple of thoughts going through my mind and its real late at night and I am tired of searching . Maybe even shiv will chime in, I am debating on which route to go stroker kit or port & polish and maybe overbore? I have a 3037 and its kinda laggy by all means at the track its hela fun but on the streets with all the lil srt-4 kids I just feel it lacks the torque at the bottom end. and for those that say stroker kit let me ask you this what compression and should i go with .20 bore as well or just stock and throw in a 2.3 stroker? also will I have to get it comletely retuned by shiv or just some minor tweaks I could do on my own? Oh well I am really tired and am sure I will have to post some more info up so I will check back tommorow for the flames im sure

 

Whos 3037 kit do you have?

 

Isn't compression based on piston design? You will need a complete new tune. I would just get a stroker...unless you've damaged the cylinder walls, I'm not sure how much an overbore buys you.

 

Stroker is the hot ticket. It normally decreases spoolup lag by 500 rpm. However, rather than dropping big money on a motor when your motor is completely healthy.....why not just put a 35 shot of nitrous on the car? That will do the same thing and probably give you better returns.

 

ok here is the deal now that I am up . I sold my secondary car dsm since I was not useing it at all so I have some extra money and I am probably gonna go with a gt35r kit not exactly sure if AMS or BR. So I am really leaning toward a stroker. Although some people say that it would be better to keep 2.0 and port polish you know basically build it up for a sick top end power. So im not sure but where it stands now I am thinking gt35r stroker, and possibly an alky kit cuz it is so hard for me to get race gas. I went to my local vp reseller and ask for race gas all he had was 103. My xede is tuned for 93 and 108, So I ask for 110 and he tells me I have to order a whole drum at over 300$ no thanks. So what are thoughts on alky kits? as in which is safest and I will prolly run denatured alcohol. let me know sorry for blabbing on.

 

Get the stroker - stock evo head is pretty good out of the box.

I have a ported head & had I to do it over I would have speant that money on larger turbo/stroker. Now after you do those mods and you want to get that last 10/10ths - a ported head might make sense.

 

Ok now that I am pretty sure that I will get the stroker. Can I just drop in the lets say ams stroker kit and I will be fine with the smart system or will I have to lets say adjust cam gears and adjust the xede a bit?

 

Oh and if shiv you happen to read this please tell me your thoughts on alky kits and your prefrence on them as far as reliabilty as well as performance.

 

I'm a little confused. You said that you already have a 3037 and you don't like the lag, but then you want to up to a stroker (will get rid of some lag) and then a 35r (will add lag back in). IMO you're going to have to really think about where your priorities lie.

1.) Do you want a great street car? (stroker with 3037)

2.) Do you want a great race car? (stroker with 35r)

Also, if you're going to go with a stroker kit ... be VERY picky about who builds it for you. IMO the source of the kit will be less of a determining factor in the final result than the engine builder.

Well, why don't we just call my car a Vishnu stage 4. You could follow my upgrade path to a tee and then use my maps for free. Then, all you would have to do is get the car fine tuned.

You better have more than a little extra money laying around...

 

Kinda off topic, but how does your car spools comparing to stock?

 

Not a fair comparison but it does show what you are asking for to some extent. This is my car compared to a bone stock Evo 9:



From 2900 to 3900rpms the 9 rules. It shows my car has spooled suffiently to run away from a stock evo 9 at 4000 rpm.

 

If you go with a stroker, Smogrunner can tell you were you can buy a couple of extra mass airflow sensors for your preliminary tune

If it helps, your 3037 will work great with a stroker.

On a 2.4 , the 3037 will give you better than stock spool from the get go and beat the 35R into the early 5,xxx's on power and torque. You feel the full hit by 4000 rpm and peak boost comes around 3100 rpm. In 5th gear the 2.4 registers it's first pound of boost at around 1500 rpm. After about 5500 rpm with the 35R, it's game over.

Above 6500 rpm, the 2.0 can slightly outshine the strokers and 2.4's. on power and top end torque from what I've seen.

You can also pick up 50 to 60 foot lbs of torque over a 2.0.

With the added torque you'll stay in your gears less time which makes these options very streetable.

 

wow what are your mods?

and as far as my 3037 goes its not too laggy but id like to get stock spool put looking at smoggys man that spool is just too nice to not look at besides I will only get the 35r if I go with the alky kit so any thoughts on that would be really aprreciated

Oh and smoggy if you want just email or pm the specs if you dont wanna post them tkz again guys

 

Oh by the way what gas was that and what psi were you running?
