GEN IV LSx engines moved a few sensors around. If youll compare your stock cam, theres a toothed ring at the rear. The TBSS cam is smooth in that spot, those moved the sensor to the timing cover. Im pretty sure they did that to allow VVT engines to use the same setup (cutting costs). A new timing set is pretty standard for cam swaps and a front cover is usually under $50. Not a huge setback

 

yea the only thing is i heard after i bought it that the stock cam that came in the 98 ls1 is better then it. but i have looked up the numbers and the ls2 tb made 390 and the ls1 made 325 so i think that cam was worth it. cam with ls6 valve springs and pushrods so i cant complain. now all i need is my accesories, oil pan, pick up tube, coil packs, valve cover and ext you get the point but i am on my way!! Here are some pics of what i slowley did to the 90 firebird. got the old dash out. gonna patch floors and get the interior from the 89 in. Now tomorow i get my block so i am going to test fit it all. so! here we go enjoy!

hopefully these are keepin my audience entertained. IT IS ME!! i cant wait to start stripping the 89 and swapping the stuff over woot

 

yo pocket here is a link to a timing cover. Is this the one ur talkin bout cause it looks like it has a spot for the sensor. now when i send my harnesses to ya will you mod that for me?

http://cgi.ebay.com/ebaymotors/Chevr...Q5fAccessories

 

Thats the one. Check on tech for a cheaper price used. I can extend the cam wires for you no problem

Dont forget the LS2 timing set which most people upgrade to even when not using the newer cam

 

yea i was going to buy one from comp. I cant find the bolt for it though.......... were should i look?

 

http://compnine.com/index.php?u=1&ye...00&grouptype=B

Dealer, according to that its a $3 bolt

 

well thats a cool site. today i started gettin rid of tthe rust and swapping so ill post pics a lil later

 

k so i got a used driver fender and headlight assembly from a frnd for 40. ill send pics when i get them to the shop. now i am waiting for tomorow to go get the ls1 from the macghine shop. so ya! but yea

 

so i am wondering. can i use the lt1 t56 if i put the ls1 bellhousing on it? a reply would be nice, cause if so ill go that route and get a quicktime bellhouseing and a ls7 clutch then eaton 3:73 out back

 

here are some pics of the ls1, and some pics.
ENJOY!





someone slap me,.....

 

tell me what you guys think bout this. the 5.3 862 castings are a smaller combustion chamber therefor creating higher compression. if i port them out they will just as much but have more compression. what catings should i go with?

 

To use an LT1 T56 on an LSX engine you have to swap out not only the bellhousing but also the input shaft. If you were still planning on using the LQ4 crank, then you would only have to swap the bellhousing and could leave the input shaft alone. I think the LS1 T56's are a bit stronger anyway so that would help you out a small bit.

 

yea thanks man. appreciate ur input i think ill just wait around for one of those deal ya no. with clutch and all so we will see got a ways to go still but gettin there.

 

So i started sanding the body down today, and i got to the driver door BONDO WOOT WOOT! like a full 8th of and inch of it awesome the sander was like cursing me out while i was sandin lol but yea,.... ill be puttin my heads together once i borrow my frnds tool then ill post pics. just the shitty 806 casting i ported nothing special for now

 

So i just met a guy tonight from the board,.... amazing had a great time showed me his toys. VERY motivating to say the least but ill have more updates later on

 

So i was thinking. I got fourth gen wheels. I need a rear that can handle the ls1. So why not get a fourth gen rear? So i found one with 3:73's already in it, for 225. I am gonna go pick it up

 

Dont abuse it and the 10 bolt will live just fine behind the 6.0. Your 700R4 will likely die first

 

ya but i dont mind the tranny. its the rear i dont wanna have to pull again. so i am gonna get the 700r4 built, i think,.... or i might get the t56. I love the t56 and sounds of haveing that kinda drivability. so..... i think i may.

 

so here is a couple updates, i got my rocker arms in the mail today, and i found a fourth gen rear for 225 with 3:73 init so im very excited. now here are a couple pics just the rocker arms get me excited woot!

got a couple questions for ya. Now i am wanting to get a fuel tank. now which is better, ls1 tank? or third gen? for the fuel if i am going with the ls tank all i have to run is one line? cause it ihas a built in reg? correct? if not correct me on this.or post up a pic diagram of it so i can understand it.Now..... ls1 castings which is a good casting i no the 317, and 243 i have the 806 they are ****!

 

To use the plastic tank you have to swap the fuel sender for a 90ohm unit, change/lengthen the fuel line fittings and trim the filler neck. V6 versions had the regulator on the rail, LS1s in the tank, so find out which you have

To use the 3rd gen tank you need a new pump

 

The LS1 tank is a bit lighter considering that it is made of plastic. Several members here have successfully been able to use it for their swaps. I'm not sure if anyone has actually been successful at getting the 4th Gen Evap system to work properly yet, but that is yet to be determined. If it were me doing your swap (I am doing one of my own), I would use the 4th Gen tank. They are relatively cheap, and the weight reduction alone (Even though I don't believe its significant) should make it worthwhile. The people that have run 4th Gen tanks merely run a T-connector either just before, or just after the filter, and run the return back to the tank. I believe, based on some drawings I saw on LS1Tech.com that the regulator is actually in the return line back into the tank? (correct me if I'm wrong here guys) so by running the T with a return line the fuel is able to be regulated.

In terms of castings, I know that Nick (Blue '91Z 6.0L vert) ran 317 castings I beleive, and made great power from them.

The 317's are 2.00/1.55 and have 210/75 Port volumes and a 71cc combustion chamber, the only difference between the 317's and the 243's are that the 243's have a smaller combustion chamber of 64.5cc, which would result in higher compression.

got all my info here:
http://chevythunder.com/LS1%20compon...ector%20ID%27s

If it were me, I'd probably go with 317's because the 243's (LS6 Heads) would likely run more money on the open market.

 

ok well thanks for the info,... and i got another question for ya guys, i was told with the arp rods bolts that i would have to have work done to the rods to make them work? or not?

 

its a small world out there, i met the guy who ones this car. his name is tony and he is very very cool guy. I meet him through here and we now hang out so pretty cool

 

well i got a set of rims for the 90 formula for 350$ here is a pic. ordered all my bearings, and arp rod bolts. gonna get the gaskets and what not when i get them all here. Now, i have been doing some heavy thinking,.... some feedback on this would be appreciated. Now as my followers no i am debating 700r4 or t56. I cant afford a t56 right now so i am gonna go with the 700r4 cause i can get a better et and itll be cheaper. (already got a 700r4 laying around) now later on i WILL be swappin it out and to a t56. So when i get my harness done by POCKET ill have him make all the connections /connectors for the t56 so when i go to swap all i gotta do is drop out cut hole and put it in.

Pocket: Will that work? is that possible? or could i just pull the harness out and have you rewire it in there? idk just some input would be nice. tryin to firugre it all out.

But ill update when i start building my longblock. ttyl!

As long as you still have a manual tune in the PCM and use an external vacuum lockup switch for the 700R4 there should be no issues

 

I know Tony also, he's awesome.

 

ya he is,.... hey bluezee did you get my message? bout hangin ou when i bring this thing to st. charles to get it tuned??

 

ah ok cool cool well hopefully it will work. i think my lock up is electronic?

 

your 700r4 will be electronic lockup now, but since you're going to a different ecu, you'll need to change that yourself. quite a few companies out there who make kits and if you dig around in the trans section here, you'll find some people have pieced together their own lockup kits too

 

ah ok i see what your sayin, sorry pocket. but thanks i get it now thanks dan. any body like the rims? i think they are sick!!

 

Ya just let me know when you have it done and bring it down here.

 

ya man i will.... what exhaust shop did you use??

 

Redline Performance. If you go to www.fastlouis.com, they're a sponsor on our local forum and there's contact info there.

 

dude maybe if i am headed that way sometime i could stop by and see ur car for some motivation. i could use that. and ill sign up there man sounds sick.

 

Get some better pics of the wheels... then we'll talk! lol

 

I like black z06's, $350 sounds like a great deal if you ask me. Did they come with tires?

 

Ya check out that site and also www.stl-speed.net and www.stlsr.com, although I have to warn you, both those sites give new people a lot of crap, just let it roll off your shoulders lol. All three sites are St Louis based.

And if you're coming from IL to Redline, you will come within about 20 miles of my house when you pass through 55/270.

 

i like the ZO6 style wheels in general and if u picked them up for 350 w/ or w.o tires you got a pretty dern good deal. If yall are from the St.Louis area we need to find a show somewere between W. Kentucky and MO. Im from owensboro and it'd be nice to meet a couple TGO fellas.

 

with tires btw.... so ya awesome deal. CRAIGSLIST WOOT WOOT

 

the tires themselves wer probably more than 350 bucks, nice steal

 

the fronts are 275-45-17 and they are brand new rears will end up needing replaced after a lil run time (burnouts ) 295-30-18 ill but mt 305-30-18's on the rears

 

LSx + =

 

speaking of burnouts, i got my fourth gen rear end today and it already has 373 gears, got it for 100 from the same guy i got the rims from so i am pretty darn excited. but it is true posi so woot woot!!!

 

k so i no that pictures are everyones fav. so i got some of the rims on the car and the rearend and some other stuff random stuff. first off


this is the spindle and control arm nut. now i turned it and the nut moves with it?? there for breakin the cotter pin...... hmmm what is the cause of this? to tight??

poor baer,...... lol all he does is sleep love him though!!
100_3905.jpg?t=1282874075

 

Put a jack underneath that control arm to put some pressure on the ball joint, it will keep the ball joint from spinning while taking the nut off. Wheels look nice!

 

no the ball joint is fine,... what i am sayin is the nut turns..... on the threads... so idk

so, i have come up with all i need to do still.

I need to order my ls1 front brake kit. 675
udjustable panhard bar 100
shocks (autozone 30)
centerlink
swap interior
patch floors
paint car
build ls1
put together engine bay
so all in all everything needs to be done but the car has come along way. so

ill update any comments would be nice

 

so i got the headlight harness put in today, and the headlight module in. still lots to do but got some stuf done today. gonna get my pan patched by next week and then start swppin interior and interior harness.... any tips on doing so would be sweet. i am actually lookin for a new or good used 89 dash. mine the core is all cracked up pretty good. making it squeky and annoying to look at so i have been finding them for like 50 bucks so ill end up gettin out and a new gauge cluster lense so i can make it look all good and stuff. but im out later on!!

 

so here is what is going on,.... I got a 4th gen rearend with 373 installed for $100, got a ls1 for $350, got a 700r4 laying around, got a car for $100, got my front suspension swapped over. Headlight wiring swapped, monday i will start weldin the floor patches in. Then swap interior harness over, then interior over. now for the near future. For the

Off topic, but Tony and I were on an Fbody cruise together back in 2006, here I am parked next to him. The green '91 GTA that is on the other side of the white TTA is the LS2/auto GTA I have mentioned before. He's another friend of mine, Jeremy (GTA91 on TGO). That car is sick, and one of the earlier LS swaps in the St Louis area.



And we also both went to Power Tour this year in Springfield, IL. He was babysitting Firehawk #13 at that event.
