I'm building a lsv it's going to be my first build with aftermarket internals here is what I got
Head
-b16 port and polished stage 2
- supertech flat valves
- supertech springs and retainers
- twm 50m itbs
- skunk 2 cam gears
- no cams???????
- rmf narrow headers and v2

Block
-b18a bore to 81.5 stock sleeves
-gsr crank
- gsr eagle rods
- SRP/je pistons P/N 149213 I think the compression will be 11.5.1
- 12 pound flywheel
- 6puck clutch

My questions to you guys
I have 2 sets of injectors blue tops which I think they are 440cc and rc 310cc which ones should I use?
Which headers should I use rmf narrow or v2 replicas?
What cams will be perfect for my build skunk 2 pro2?
What you guys think about my build anything is fine is it bad ?..

Thanks guys

 

got no problems with the head. and cam choice will depend on what the motor will be used for and how much power your trying to get and where in that rpm you want to make your power.

as for the bottom end i have some issues. so your using a gsr crank inside of a ls block? you have the drawbacks of an ls vtec in the using of an ls block, but none of its advantages without the ls crank. im sure it will work just fine but its not really an lsvtec by many peoples opinions.
but in the case that your stuck with what you got i would go with RDX injectors, rmf narrow rep header and maby pro1's or blox hsl's
good luck

 

Technically, since you are using GSR internals, it's not an lsvtec. But not like that matters for your question.

I would go with something like 600+cc injectors so you have room to play.
Skunk2's will be fine for your setup.

As for the headers, what are your hp goals, and are you looking for top end or bottom end?

 

Why are you using the GSR crank over the LS 89mm stroke crank? I would use the LS crank in that setup.

 

Thanks guys I'm using a gsr crank cause I got the eagle rods for a gsr of a friend so I took a cheap way I do have a jdm ls crank I can use I'll just have to buy some rods so u guys recommend ls crank I'm hopping to get some good power it's going to my weekend car would like to take it out here and there to some tracks but they all 1/8 mile around here thanks

 

With the GSR crank and rods there is a better rod/stroke ratio, better for revving higher, but the LS has a longer stroke, so it's better for bottom end torque.

I vote LS crank, sell the GSR Eagle rods and get LS eagle rods, they you shouldn't really have to spend any money, just sell the eagles for the same price the used ls eagles are going for.

 

ls crank will give you more power in low rpm AND more power in high rpm if you build it right.
do your research on lsvtec building before you go any further. do it right the first time, rather than doing it twice.

 

Thanks guys ls rods n crank it is so I'm going to sell the gsr rods n crank also the 310 injectors how's the pistons for u guys are they any good will they work and I think I'm going to end up with some pro 2s

Another question 12pound flywheel or 8 pound ? Thanks for your help

 

I like my ACT streetlite ALOT for DDing. Quicker revs but the drivability on the street with loer rpm shifting isn't bad. The 8lb ones IMO drop RPM too quick and unless you shift fast all the time can be jerky.

 

Yea go with the 12lb, and SRP 11.5:1's would be great.

 

Thanks da9 I have all the small stuff new water pump oil bump gaskets belt should be ok I also got the arp main studs how much power u think I'll be making 200whp ?

 

Ditch the ARP main studs, not worth the machine work needed (align hone/bolt hole bore), and they aren't necessary, factory mains are unlikely to fail.

Get a walboro 255lph fuel pump, maybe 600+cc injectors, and a good tune. With the skunk2 cams and good bolt on's, you should make 200hp.

 

i agree

why so friggan big!? anything over 450cc injectors are too big for this build. id say go with the RDX turbo injectors. i believe they are 410cc.

agreed, but there are many cam options out there besides skunk2. some that other people may consider to be a better bang for buck =]

 

Because, you can always adjust pulse width and duty cycle, and when he decide's he wants more hp or to boost it, he has room to play with the injectors he would already have in.


Very true, they are just the most common recommendation, personally, I'll never use skunk2 parts.

 

So what cams would u guys recomend and sorry I don't have the arp main studs I have the head bolts arp I'm trying to get the most power I can with this pistons

 

JUN 3's, Toda B's, S2 Pro 1's would kick *** with your setup and still be great for a DD app.

 

It's not going to be my dd so not to worry on going crazy lol but yeah I was thinking about the Jun 3

 

Nothing personal, just curious as to why you feel this way? Their valvetrains and camshafts are top notch and proven. Now if we were speaking of suspension I would be right with you...stiff and bouncy FTL.

 

Since it's not going to be a DD I personally would lean on the bigger side of cams then and tune the hell out of them. I think pro 2's with the correct supporting mods could be very beneficial if you find someone who cam tune them to a "t".

 

Yeah tb is going to tune my stuff once it's ready so pro 2 will be good how's the stage 3 skunk 2 cams seen a couple for sale any what other mods can I do to it ? Besides sleeve it

 

Don't even look into stage 3's, your motor is nowhere near big enough, pro 2's are big enough to put to use by a 1.8. You dont need to sleeve it, stock sleeves hold a decent amount of HP, alot more than you will be making. I dont know what kind of budget you're on but header wise my 3 choices would be the new Skunk2 Alpha, the SMSP "1.9" or the RMF narrow has been proven to be a steady and competitive performer on all 1.8 setups I have seen. Only 2-3 HP difference throughout the power band against custom headers such as the smsp or the alpha. Peak was within 2 hp. Stay away from the Bisi or bisi knockoff junk...you will only go backwards.

If you have not bought the pistons yet I think 12:1 might be a better number to shoot for since it will not be a DD and you plan to run BIGger cams...making power with them will be much easier.

 

I'm just not a fan, I feel there are much better parts/companies out there. I just remember when they were skunkworks I thought there parts were poo... Just my opinion though... It's a personal preference. I know a lot of people use them and love them, so I'm not knocking them, just saying I won't use them.

 

Yeah I got the rmf narrows I was doing a lil more research on the pistons I got and looks like the cR will be 11-7-1 using the b16 head should I use a high compression head gasket to bring it up a lil I'll post pics tomorrow of everything I got

 

Is the 11.7:1 figuring in the flat faced valves and any milling that may be done to the head/block? I would use a a cometic dual layer OR if you feel you are capable a single layer and 12:1 should be in the mix. Especially with the flat faced valves.

 

I like that.. At least you were honest about personal preference. (For me, they're one of the only American-based companies I'll buy from.. Everything else is basically from the older school companies (GReddy, Apexi, Jun, Toda Racing, Buddy Club, etc).

Ah the Skunkworks.com days..*sigh*
