Buy a decent header ASAP.

New TB would be good too , but header definitely 1st

 

Any suggestions in header choice? company name info?

 

i suggest a larger tb,

 

Header and larger TB is a good start as stated, how much are you willing to spend or change up?

 

2 grand, want oget into the 230s

 

2 grand want to get into the high 230s

 

Whats the reasoning behind the second tensioner?

 

Also, not all ported heads are created equal. Who did the work?

There is Quite a lot of play on that side of the timing belt. You can see it more while the engine is running and you put it under load. It actually flaps around quite a bit.

Vibrant makes a very nice second tension to take some slack out of the tbelt on that side.

Obviously people are fine without it , but I like the peace of mind

 

It was a rhetorical question

I was hoping someone would chime in with some hard evidence. Since the ignition is run off the intake cam gear, a belt that is more stable SHOULD improve high RPM timing accuracy. Was hoping for a back-to-back dyno.

I could probably do a dyno test with it on and off next month if you'd like sir

Imagine that. Real tech.

 

you're power #'s seem to change depending on what forum you're posting on.

I thought you already made 224whp?

I'd get a better header to go with your 2.5 inch "manrail" exhaust (lol....sorry i had to).

I thought you already had a larger throttle body? The one you were selling on TCC/TI/JDMR? A larger t/b could help with the top end power and maybe add a few peak whp (if thats what you're after).

 

2.5"'s is a small *** manrail. no wonder he's searching for more power......

i hope ur saying ur prayers and eating ur vitamins, cuz those guys machining process' and assembly is very poor

SMSP B19 header/Pro2's or M24x/put a velocity stack on that intake and your there.

 

headers and new tb yes for sure but what about tuning, maybe new cam gears and adjusting the timing?

 

tb, headers, change up the exhaust - - aside from that I'd be looking at the internals again, different tuner or tuning program -

I was gunna suggest this as well.

 

was making 224whp but for some no appearent reason i lost whp, i think it might have somthing to do the the gearing in the transmission 4th seemed long.

Update: put a 70mm throttle body made 231whp.

still same 4-2-1 vibrant header.
