I do Eric! 4 of em. Green and all.

Good to hear you got the injectors in JapE. I cant wait to get my cams in and have some of that Koolaid!

I see one or more of my heads has been heavily discussed recently in here lol

From what Im gathering they are saying your head has been really aggresivly ported (hogged) (correct me if im wrong guys, Im not paying enough attention) But I know you got good results out of it.

Its pretty aggressive yes, but the ports aren't as "gaping" as some people seem to think. It fits my header almost perfect. Also, the ports on the exhaust werent the only things touched, which I think is known. Another thing is how my header and downpipe are setup and the transition between the 2. Nothing too out of the ordinary, but some thought went into it when we welded everything up.

The car is definitely happy more so in the higher rpms, but I don't feel as if I lost any low end. Before I had the ported head for the month or so I had the TVS on I felt like it was a little pokey in the lower rpms like most people seem to experience, but after the head swap that seemed to disappear. However, I still start my 60 rolls in 2nd when I need to

Ok I think thats what we needed to hear. There has been a lot of discussion about power lost down low with a ported head.

A lot of it has to do with how much air you are moving. Like putting huge turbo cams on a car with a small turbo that just cant provide the airflow, a head with a ton of material taken out but running a 3" pulley on an M62 may not give you the most desirable powerband for example.

Ill give an example. I used to be able to feel exhaust gas about 8in from the tip. Now i can feel exhaust pressure! At 2feet away

iTrader: (4)

Yes. I have decided that I want to be like one of the cool guys and refer to ALL LSJ injectors in CCs.

357cc = 34# injectors.

It's that so cool?



Just for you! lol

deeeerrrr, but i has lsj deeerrr...





hmm...thanks bastards, stock will be plenty of power for my goals, YET all this talk makes me want to pull head and port exhaust...which if i did that, id be tempted to do pistons, possibly cams, valve springs/retainers, rockers, neutral balance shaft/balance shaft delete...

essentially a full build....


thanks ********!!! !!!

Well this thread is going to be a long read to make sure I really want to do this, and that I will get the results I want out of my car. I am thinking about just stepping up and going with a TVS and taking it to ZZP to tune it for pump gas

iTrader: (5)

I'll save you the read. Get it

RooTBeeR

iTrader: (4)

if you like to punch it and go like the m62 does?

then get it, it does the same thing, just goes mo-harder!

TVS is cool, built TVS is cooler

What are you saying then? Its a waste unless you are fairly built and plan to go e85?

If I could do at least 300 whp without going into the engine and running 93 pump, that is good enough for me for now

RooTBeeR

iTrader: (4)

not a waste, but if you have E85, i'd run it.

i had my tvs on stock lsj and 91, didnt make great power. but when i was on 93 i was 275-280 and that wasnt a finished tune at all(not that im great at tuning anyway ) so it can be done

A 128ci ecotec is pretty bad ass! Way better then 122ci or 147ci.

I wonder if I could get Harrop to change the TVS1320 to reflect our American heritage!

mrbelvedere

iTrader: (3)

well that's not a good one you can get that from swapping out the just the muffler or changing the cam timing or by just freshening up an engine

a 147ci would blow a 128 out of the water any day of the week
