lq9 or ls1
1. Should I stay with the LS1 block or go with a LQ9 for strength and ci purposes?
2. Forging all good crank good rods and Pistons How much power can i reach but not sacrifice drivability will have a good tuner?
3. is a pt88 to much turbo for a street/strip build and if so, what is a good turbo i wanna make like ....800hp no joke.
4. whats a good flowing intake thats a ideal price not no hogans or marclla intake or nothing like that. somthing reasonable?
5. can i run my stock ignition or do i got to upgrade and use like a big stuff 3 or anything else?
any info will help when i start i plan to post a build thread. Thanks.
as far as the turbo i'm not sure you need an 88mm, assuming you meant rwhp and not crank a T6 BorgWarner S480 turbo should do the job. if you meant 800 crank then i would step down to the T4 series just to help make the car a little more responsive on the street.
making the car reliable and streetible shouldn't be too much of an issue with a decent tune, finding traction might be a different story lol.
again this was just a noobs $0.02, hopefully some others can jump in and give a little more specifics for your setup. one thing i didnt see though was what fuel you planned on running? also if you plan on running pump gas do you want the 800hp on 93 oct or are you looking to have the setup peak at 800 on race gas at the track and just run pump whenever driving on the street?
good luck with the build. it sounds similar to the one im planning.
1. If you can get a good price on an lq9 go for it. the ls motor would do great too, but if you can get more money for it sell it for the iron block
2. stock crank is strong but do forged rods/pistons
3. a pt88 would work great, but a pt7675 is smaller, spools quicker and makes great power too especially since you are looking at 800whp
4. ls6 intake and put the money you saved towards a better fuel system
5. stock ignition works great. again use money elsewhere.
With that said, I have recently ran 6.07 @113mph and had a best mph of 115.92mph on only 10lbs of boost. This is with a LQ4, an XER273 cam, patriot gold springs, junk 862 heads off my old 5.3, and LS2 timing chain, NO ARP rod bolts, and currently the stock head bolts. Edelbrock Pro Flo XT intake and twin ON3 chinese 70mm turbos, on factory pcm, low impedence injectors, and HPtuners on E85. The best part is the car sounds pretty subtle and averages around 20mpg's. It was 22 when I had a 5.3 in it. With the 6.0 I am at 18-20 depending how I drive it. Oh and the 6.0 was from a junk yard with a 170,000 miles on it.
