Well I am hoping to hit close to 300whp with a stock LS in my rex i am just gatehring parts right now and would like some suggstions for a couple things

I have 390cc injectors those need to go but I don't think even 450cc would be ok...i didn't really feel like spendng mad cash on injectors but looks like i might need to, i am building an LS or Ls/vtec to eventually go in with a bigger turbo and more boost so should i just get the 450 and let it go till i want to up the power or just get bigger ones now to be safe and how big, is there to big?....

I was going to get a stage 3 clutch(clutch specialties) but that also seems to be at its limits around 300hp

I have T3 .63/.60 capable of 300hp but thats about it will this thing choke my 300whp goal?

Well this is just a project car and this set up is just to get the B swap over with and turbo on it while I am building a better motor to make more power with...I don't want to waste a lot of money now and then have to upgrade later, thanks for any help...Matt

are you staying obd-0? using turboedit for managment? and i think 300 whp is doable on dsm 450 injectors, prolly wouldnt hurt to have 550's though.....and for your turbo, a 63/60 t3 should get you to 300 whp but its a stretch, you should go with a 57 trim t3/t4

Staying with OBD0 and turbo edit for now but eventually will go to OBD1...If 450 will do it id rather get some for $50 than have go bigger seems like after that i would need to look into some RC and pay alot more for them, say with the T3 I have it so if it will do it i'll keep it, I'm still collecting parts for the swap the suspension and turbo kit so i am trying to keep cost low and use what i have if i can, thanks for the input...keep the comments coming

why would u go obd1 if u r going to use turboedit?

Loserkidwac

No I am already using Turboedit, when i get my other motor build I will proabably upgrade to OBD1 and then use uberdata or neptune...turboedit is only for OBD0

Here's a little info you can read up on injectors and some calculators: http://www.megasquirt.info/v22manual/minj.htm#size


The only downside to bigger injectors is that the bigger they get the tougher it is to get a smooth idle

but still i dont understand why youd convert to obd1 if you can use what u have now just fine?

450's should be fine.

Thanks Whitey that helps a lot

as for going OBD1 just seems to be more options I have a b18b I am building and and probably going to make LS/Vtec seem easier to just get a vtec ecu and convert to OBD1 rather than use a rpm switch or v-fac and uber seems to have more options than turbo edit...OBD1 seems to be where all the good tunes are yea there is support for the OBD0 but I think OBD1 is better...I guess it is all an opinion but I am using turbo edit and will before this next motor but whent he built one is finished I am probably doing the conversion...do you have any info why to stay OBD0 and not convert? or just because it is already there and working, kinda like don't fix it if it aint broke?

B16CRXT

exactly. and why spend money if you dont have to?
