are the ls1 swaps on the 2nd gen similar to 3rd gen?

level of difficulty and parts etc

MDoe8

2nd gen is easier and cheaper. More room to work with, jsut requires a subframe adaptor plate, not an entier subframe, etc. Level of difficulty depends on who you're talking too. I personally don't find it hard to do anymore but when I started the project, i felt I was in over my head. Just takes time, patience, and a little bit of money...but it's worth it in the end!

You need to be more than just an average oil change guy for sure when your doing something custom like that. I have considered doing an LS1 swap someday whenever my stock motor gives it up and I have assisted on several engine swaps-and it makes me a little nervous. I have also figured up some caluclations on financial's...and the way LS1's and T56's keep going higher and higher...you need to figure on AT LEAST 5,000 bucks to get it in the car...bare bones. That's not counting any differential work or suspension work, wheels and tires, etc. either to get that kind of power to the ground.

wonder what kind of 13bt you could build w/ 5 G's?


FC is def easier and much roomier plus there are more of them.

they are going to ask u to look into the "other engine conversions" forum
and that forum will tell u to go to v8rx7forum

why dont u do a search anyways

if you're going budget, no doubt go with the 5.3 liter. it's a ls based motor and you can get a complete motor with less than 50k miles in perfect running condition for $500!! Slap an ls1 style intake on it and a healthy cam...viola....400 horse.

Correct me if im wrong, but I thought the only 5.3 ls motor thats all aluminum is the ls4 and thats mounted transveresly and wont fit in a fc engine bay.

you're correct, but he was talking about a budget build and the 5.3 truck engine is cast block. i've heard alot of good things about that swap.

Does anyone know what trannys can be used with the LM7 and L33 5.3 chevy engines? Ie can the t56 be used?

I believe that any of the LS series motors can be used with a T56 as long as you have an LS bellhousing. You can also run a 4L60E or a 4L80E out of a truck.

a thread just popped up about that on v8rx7forum. apparently some of the chev v8's have a different crankshaft length, and so certain t56's wont fit (i didnt bother to read into it)

what do you mean ls4. can a ls1 still be a direct bolt in with a kit . and if i get the hinson kit is it a straight swap in or is more fab work needed. ..


also what kinda rear ends are people using to do these swap i know the stock cant hold up to all the power....

actually the stock one can hold the power, well, the stock Turbo 2 diff. the weak point isnt the diff, its the stub axles. But with a pinion snubber, and a mazda competition front diff mount, it holds up fine.

I heard somewhere the stock turbo2 diff will hold 350rwhp. I make 356hp and mine is just fine. not a single problem since i installed it. ( I snapped my NA stub axle 2 or 3 days after getting it on the road )

The vendors of v8 kits (hinson and granny) make this a bolt on solution. Very LITTLE fab work. honestly, the only thing you really need to do is cut the humps off in the transmission tunnel. 10 minutes with a sawzall and your done with all the fab work. You'll also need to drill 4 holes for the transmission brace. not a big deal.

The easiest, most non-headache way to go, is getting a full LS1/T56 pull out. Sure you can save a few bucks going with a 5.3L, and you might be able to source an engine and trans cheaper if they are seperated, but it will be a much bigger headache and time waster hunting down parts.

IMO, 5.3 isnt worth it unless you have an Ls1 laying around. You will need more than just the intake. I might consider an iron block 5.3L if i ever blow this one up. (notice i said IF, not WHEN. that is one of the benefits of NOT owning a rotary. ) But if i can get an iron block 6.0 i might go that way too. Lots more options. LS series engines are wonderful and the after market is tremendous.

that is one opion i like is the market for a ls1 is so open right now. now what kinda rear end could work if i say wanted like 450-500hp out of a ls1 which i know is very possible.

theres a guy (or two) making cradles to put a cobra diff in the car. all said and done, i think it costs ~2k. worth if if you're makig big power.
if you dont mind losing the independant rear, granny's has a ford 8.8 live axle kit
