I have an lsvtec that consist of:
LS bottom end
LS crank (micro polished)
ACL race bearings
Stock rods(reconditioned) with ARP hardware
Nippon PR3 81.5 mm pistons
OEM P72 oil pump
OEM Water pump
Cometic thick head gasket(forgot the thickness to be honest)
B16 head (milled/resurfaced)
type r intake manifold with omni 70mm throttle body
ITR Valve Train
Crower Stage 2 cams
Golden Eagle Cam gears
Golden eagle LSVTEC conversion Kit
walbro fuel pump

Car made 199whp without messing with timming cams etc now my question is what will I have to change in order to be able to be turbo but reliable I would like to run 8psi for low boost dd and maybe 16 psi high boost I would like to be in the 350whp on high boost. I know there are plenty of variables like turbo, injectors,intake manifold and exhaust manifold but what would be a decent route to make around those numbers.

Thanks in advance.

dude with that build you should hit 350 @ 8 psi on a t3/t04e .63 on the compressor side...its all in the tune so make sure you dont skimp out on the price involved unless you know people who really know what the hell they are doing. high compresson + boost can be done, but it can be done wrong easier than right. cheaper in the short term also...but youll pay for it later..

First of all, dont base your goal in terms of PSI...its an irrelevant term that varies by turbo and between setups. Instead, set a power goal and work to achieve it.

What is the compression ratio? What fuel do you plan to run?

The tuner is a very well know down here, I know that why i wont cheap out on anything for this build.

I said the psi because that was my limit as far as psi because of my stock sleeves and dont want to be with a lot of pounds but makes sence what you said, thanks for the info(I'm very new to this). The head was milled and I was not sure how much so i went with a ticker cometic gasket to be on the safe side since it was going to be a fun little dd , i did a compression a check and got 210-215 in all 4 cylinders. 93oct pump gas.

What did you set ring gap to?

allmotor-teg

The engine was build for me I didn't build it myself so I don't know to be honest.

note: i was just throwing some numbers out as an example..

he didnt say anything about the compression ratio so i referred to one that i had used on the stock b18c5 on boost from experience...he did refer to psi of intended boost so i figured if he made 199whp that would probably mean at least 11:1 so youd want to use a smaller turbo because it would mean less cfm. cfm is the really important part most people overlook...anyways i ramble but i lost interest in explaining myself.

CFM or Lb/min (you can convert between the two) are the measures you would actually use when deciding which turbocharger is right for your setup.

On 93 oct with ~11:1 compression, you should be able to reach your 350whp goal but unless you really trust the tuner, it might not be a bad idea to lower those goals slightly (320-330whp). If you were running E85 or race gas, 350whp is easily within reach.

The tuner is a well know tuner down here, couple people I know have tuned their cars with him, he tuned my current setup 2+ years ago but I get what you are saying, what about the turbo sizes for that setup? You are saying 320-330whp for my high boost or dd?

pr3s in an ls with b16 head is close to 11.7:1. still do able just watch your ign maps on pump gas

allmotor-teg

I will keep an eye on that, thanks man.
