Question Recommend me a turbo for my 69 Prostreet Lq4 build possibly with Epp cam..

I am doing a Lq4 in my prostreet. The shortblock for right now will be a stock Lq4 with ported heads (not sure what im gonna use yet) But im looking to figure out which turbo is gonna give me the push that I want to get a min of 700rwhp through a t350.. I believe Im gonna go with an Epp blower cam and if not a custom grind to give me the power with the old school muscle car sound with the lope.. Any suggestions will be greatly appreciated along with suggestions on Blow off valve ect... The shortblock will be upgraded next winter.. Been seeing alot with the mp t76

Alot of turbos to choose from, MP T76 like you said, TC78 $1000, T4 S400 $800, T6 S400 $600, probably ten others, ported heads and a huge cam are not needed for only 700whp on an LQ4

Any of the above mentioned turbos and as far as supporting components I like tial and turbosmart. There are so many options it'll make your head spin. Give forced inductions or kytp a call they will hook you up.

Should be ok to use a tc76 or 78. Not sure if the mpt76 would get you much over 700rwhp without maxing it out.

Really need more info, like how fast do you want to go, but

cam - TU3 from Speed Inc or custom from VA Speed

boost control - JGS or TIAL

Prostreet means at least 2x61mm or an 88mm.

To get 700 you'll need an S trim (75mm) turbine- which would mean MP45 if you stick to master power or a 76GTS/HPS. The TC or Q are 68mm and will choke a modded 6.0.- https://ls1tech.com/forums/forced-in...-new-best.html

S475 w/83mm (best bang for buck) or S480 w/87mm turbines may be a better compromise if you don't want to buy twice.
PT88 or twin MPT61 or 70 would work for the next motor too. (low-mid 9 sec power easy)

Talk to Jose at Forcedinductions- twin GT61's are a good all around setup or those mentioned above.
-It's as if GM designed the 69 camaro core support for twins-

The new Holley or Edelbrock intakes look the part.....

Plan on T6 or doing exh twice or 700ish hp limit if going single T4. -Theres a few exceptions to this, but you have the room-
