im considering changing out my injectors i have a 99GP SE with a 3800 i have a wizardair box 85mm MAF catless 3"DP and plan on getting the injectors when i get the stage2 HV TB from ZZP here in a month. what size do you guys recomend and how could i figure out what size i need in the future

The next step up is 42.5# injectors but don't waste your money dude, you're not even close to maxing out your stock injectors.

Buy the powerlog you want instead.

its a N/A 3800 dont they come with 22# the S/C 3800 has 36# or am i wrong

yeah your correct, you could upgrade to 36, but with your gt your not maxing them out yet, get some other mods, heck you can even run the gt inj with the ssm90 kit but you have to run a 4.0, any lower and you need 36, but yes dont worry about them yet get some other mods, heck top swap and intercool then u can run dome 42's

Oh, sorry, you are right. L67's are 33# injectors actually.

I still doubt that you would be maxing out your injectors already though.

You're not maxing them, don't waste your money

ok then and am i following the rightpath by cleaning up the intake and exhaust b4 i dig into engine internals?

Yup yup, you are going in the right direction.

Plan on going boosted at all? If you are thinking about dropping an M90 on there, skip the TB for now because you won't be able to use it.

But if you go turbo, that thing will work wonderfully with it.

Also, the 3800's have a rock solid bottom end. ZZP's got a twin turbo, 700+ hp drag car that runs 8's in the quarter and it's on a stock bottom end.


EDIT: You may want to drop some colder spark plugs in there and a colder thermostat if you haven't already.

i have ngk tr55 and i want centrafugal superchared and i just installed my drilled 180 tstat today in the snow. i do have a question on the valvetrain though i want zzp's gt1 cam but i also want different rockers which one should i get first and whats the largest rocker i could use with the gt1 cam? i know that the 1.9 wont work.

I'd suggest you stay wwith the stock 1.6 rockers with a GT1 cam ,there is nothing wrong with our rockers spend your money on more usefull mods.Chico(pops)

If you are going centrifugal, don't bother with a GT cam. Do your research before buying the wrong cam for the wrong setup.

charging it will be the very last thing i do changing a cam isnt too bad

Have you ever done it?

no but a shop can do that for me i cheat on the hard stuff if i can besides its gonna take alot of dough to do a custom setup for the charger so thats why im putting it off till i got everything else beefed up mainly the tranny

So you're willing to spend $700 bucks so your GT can run a mid 14, instead of saving the money and putting it towards the CSC and your beefed transmission?
