im new to the site also new to turbos and ls swaps I have 88 chevy that I am putting a 5.3 lm7 in I also have a t4 turbo that I want to put on it and is it possible to put down 550hp to the ground with this combo im just looking to get started and trying to figure the best way to do that thank you
Yes it has been done many times, but will take a lot of supporting components.
what other supporting components.?
Fuel
60lbs or bigger injectors
Big fuel pump aero 340 would be good.
transmission rearend etc
yea I have a 12bolt rear with 4:11 gears and a fully built th350 trans with 3500 rpm stall and trans brake and manual valve body just trying to get a pretty damn fun street truck if you know what I mean
Ya it's possible. As long as the turbo will support it.
Fuel upgrades above a d a decent amount of boost on the stock 5.3 should do it.
ive got the motor torn down it had 150000 miles on it and the bearings looked new what kind of cam do I need to look for and where can I find the turbo hook ups or dose it all have to be custom made
What are the specs on the turbo
02camaross has had great success with the speed inc TU1 cam in his 5.3 or the isky 215 cam if you want something more mild.
all I know is the turbo is a gt45 im new to turbos I can look the specs up,, and im looking for a thumping good street cam that will give me all I can and as far as for the turbo will the stock 706 heads work or do I need new ones or can I shave these valve job and a good port and polish job work ??
Do whatever your budget allows.... Better flowing intake system will help yes. TU or isky cams are a good way to go. You need to do some searching. There's dozens and dozens of builds like yours on this forum alone.
Yea I knw its a commin build thats why im headed that direction just alot of modification work compared to my lil sbc carbed eng.
im going to be running a gt 45, 76mm turbo with a 1.15 A/R on my lm7. i have heads, tr 220 cam, walbro 400 fuel pump with the hot wire kit, 80lb injectors, and a 4l80e with a multi disk. my builds not super crazy, but should get the job done. i think ull have fun especally since ur alot lighter than me. id deff get a cam speced if you plan on getting one, if you do heads you might as well to the Tbss intake swap as well.
thanks for the input and yes cam and head work is a defanent and i was thinking of going with the holley efi high rise intake dont know if that is a good dession or not but we will see
ya ive heard mixed reviews on them myself? i know alot of guys eather run the tbss or the fast intakes
Fast intake is a no no for boost. The TBSS is possibly the best budget intake around. The high rise in my opinion is most effective for all out builds.
I hear that the high rise just looks so dam good on ls motors just haven't heard much on them and im trying to build a bad street ride plus I want it to look as clean as possible too
x 2 on the tbss intake tho alot of guys run them. i would be but i got hooked up with a manifoild with the dude who did my heads. but sounds like your builds going to be alot like mine. ull want a new tranny, rear end, and a good stall to go with it all. if you were to build like my truck " same motor and turbo set up" ur looking at 13k or so for it to be done on a budget. thats with heads, cam, fuel, tranny, converter, rear end, turbo set up, and gauges.
heres my bill
cam- $900
tune- $400
heads- $800
turbo kit- $4700
gauges- $ 850
tranny- $ 1100
stall-$1100
rear end- 1200
fuel- $750
and im sure $1000 spend on mic, and stupid crap.
Can back you up on the pricing there my friend. Spent 12K on mine. ~520Hp and 630ft*lb on 13.5psi T72 turbo. Had 130000km on the engine-looked good but blew a hole in piston 7 on the dyno on the last pull. So now going to a 5.3 bored to 5.7 with forged pistons and crank with 243 heads for more boost and reliability.
Stk rear end though :)
ya'll should have just pushed 25psi thru a stock 4.8L and make 1200hp all day.

I'm suprised you guys haven't been churning out 1000rwhp stock bottom end 4.8s right and left...they should be a dime a dozen at this point! AHHAHAHA!
Hey why is the FAST a "boost no no"?
Does it come apart under boost?
I thought I saw somewhere on ptnet where someone showed significant gains on a turbo ls just by adding an lsxrt?? Even more gains than just a straight NA swap.
I'm curious because I have an LSXR w/ 102mm tb that I'm considerng throwing a turbo onto. Would be fairly low boost because of 10.8:1 c/r and slightly larger cam that I'm not going to change at this point...
