Not sure where to put this, but I thought the force induction section would work. A little background on the motor. Built GSR motor sleeved, 81.5mm wiseco pistons, eagle rods, etc. We tuned the car last march making around 330hp with a t3/t4 .57 on pump gas. I’m using hondata S200 with precision 1000cc injectors.

My question is from March until like Oct-Nov this car started up like a champ. On start up you could barely turn the key and it fired right up idle great. From Nov-current it slowly started to starts up like poo. I would turn the key and have to hold it a little longer for it to stay running and it would idle around 200-500 rpm. Or hold the gas down a little to keep it from dying. Engine itself sound like crap like its getting flooded with fuel. Sometimes dying multi times before I get it started my afr gauge showing past 10.

Here the thing after its been running for 4-5 minutes it runs fine and idles fine. AFR goes up to around 11:5-12:5 since it not fully warmed up yet. My tuner suggest I get S300 and retune because S200 are known for this kind of problem during very cold weather (Kansas). Just wanted your guys opinion before I drop $1000.00

P.S Random question I’m using a blox IM and wondering if I should switch it for a different IM.

 

s300 has a lot more adjustability when it comes to cold starts and things of that nature. s300 will be well worth your money.

the victorx intake manifold works really well for the $ on a set up like yours.

 

So with my issue it probably is the s200? And with the victor x I'm only making power to 8k. I thought victor was for high reving engines? And the car is mostly for street and is my DD. Let me know what you think.

 

s300 doesn't cost $1000

You can upgrade from s200 to s300 for $395

For your setup, the victor x manifold will perform well but I would spend my money on other things like a better turbo or some skunk2 tuner 1 cams & valvetrain first.

 

Well i was figuring buying s300 and retune under $1000

 

I wouldn't waste money on the manifold either. You can still make a lot more power than 330whp on your current blox.

 

you check your plugs? i'd just retune for the winter
