Is this going in an F car? If so how do you plan on fitting this?

boosted383

Yeah 02 z28.. and ill get a 4 or 6 inch cowl hood. And its not a deff that im getting that intake might go with fast lsx-r intake with 102mm tb. Just liked the look of the holley intake and tb and its a good bang for the $.

boosted383

Any body willing to help me out with some info?

What about going with a super vic/4150 Tb setup, or a pro-flo XT. either way say goodbye to wipers and most of you're cowl. FWIW I have no regrets about cutting my cowl to fit the super victor, well worth it. the AFR 230cc cylinder heads you suggest would work, maybe mill them to get the desired compression ratio. For the cam I would suggest a shelf cam that's designed for a turbo setup or if you wanted a custom cam call Martin@tick, Brian tooley, or any of the excellent LS cam guys out there. Cant go wrong with any of them. Now the transmission, I would suggest a 4l80E. this is just my .02 so take it for what its worth. Good luck, sounds like a sweet build.

Changing up my fuel system going with:

-Aeromotive Eliminator Stealth Fuel Cell. With intank eliminator pump
-Aeromotive Extreme Flow EFI Regulator designed for eliminator pump
-Injector Dynamics 1000cc Injectors

Does any one know if theres a sequential manual transmission out there to put behind an ls1? Or has anyone evin heard of this being done with an ls1? Been searching up and down the net for one of these for my car or one that would fit the car and have had no luck at all.. Iv seen these transmissions in a corvette on youtube but thas the closest thing iv seen related to gm and these transmissions. Any info would be apreciated

The sequentials are extremely expensive. I don't see you gaining anything for that amount of money unless you're doing some serious road racing.

As far as automatics go, its up to you. If you want a 2 speed, powerglide. 3 Speed, TH400, overdrive and lockup, 4L80e.

As far as manuals go, the tried and true T56. You'll need a fairly well built one if you want it to last.

your turbo choice is on the small side for a 383, I prefer wiesco pistons and your target static compression is on the low side.
I would go with the smaller 95 mm tapered bore Holley for better drivability over the straight bore 105 mm, with boost there will be very little difference in performance between the two.

I personally think that the turbo is also too small. And I would bump up the compression to at least 9:0-9:5. Is there a reason for such low compression? Wouldnt that turbo max out sooner being that the turbine size is smaller and it could only hold a certain max PSI?

Make sure that you do not use a cam with a lot of valve overlap with the combination you're building. With that turbocharger on that size engine, it will be very easy to "overrun" the turbocharger.

In simpler terms, the engine wants more airflow than the turbo can give. Causing back pressure issues and power loss.

boosted383

Going with afr 230cc heads with 65cc combustion complete with parts. With them heads ill have 9.06:1 cr. Going twin turbo instead of single with turbonetics t7575 turbos. Turbos still to small? I changed the build a lil bit to. this is going to be a track only car now. Dont feel like going threw all the bull to keep it on the street.

I suggest that you check cylinder wall thickness (sonic testing), at your power level the walls will deform if there is not enough material.

Good luck

JoeNova

Those are some pretty damn big turbos for twins haha. Thats about 1800 HP worth of turbos.

Also adding in dmp engine girdle

boosted383

yeah alot of people say that. But I read about people pushing 1000+whp with ls1 block with out the walls deforming cracking or anything bad happening. I know the risk is there but ay life would be boring with out taking risks. Lol. And if the block doesnt hold up ill get an iron block and start another project.

IronBlocked

Now that's a man talking, best of luck with the ole LS1, although the 3.905 bore scares me a little.

rkreigh

nice build, if the ls1 block scares you, I have a fresh 4.8 build

nice selection of parts

interested in the dmp girdle

thanks for posting

I think that 1800 might be a good start

boosted383

Im thinking injectors might be a lil small.. anybody think the same way? Does any one kno if aeromotive ls1 fuel rails will bolt up with the holley high ram intake? Jw cuz Im trying to go with a red and black theme. I kno the intake comes with fuel rails but instead of black I want red.

rkreigh

I ran the fic 127s with a whiff of drugs (meth) to be safe

I'm thinking of going with a stronger direct port meth setup and welcome the dependency

the haltech has some nice safeguards if there are issues to cut spark or dump boost

boosted383

not sure if I want to take a whiff of drugs. Mommy told me not to give in to peer pressure and be a leader not a follower lol. Daddy would beat my *** lol.

Heard some things about burning out piston rings and things of that sort. What are some pros and cons of meth
