2jz or Ls1 for s13 swap?

[l314ckhe4rt]

hi guys i am new here i have an s13 with j30 differentials and i can't come my decision on which engine to go with. i oranginally had a base model rx7 shell for an ls1 but then when i saw the 2jz build they didn't have the swap kits for fc rx7 so i had sold the rx7 shell and bought an s13 for 2jz swap. after doing great research i have found that 2jz is very expensive.

[l314ckhe4rt]

questions for u guys:

what is the cost for an 2jz and Ls1 if i do my own labor? what is better for the s13 the stock 2jz or the stock Ls1 powerwise? which motor has more potential and is durable?

[OutToWinPAHC]

Both are money sucking projects, both can make great horsepower, and depending on what version LS1 and what version 2JZ they can be similar in power.

Swap kits are available for both. Are you a inline turbo guy who loves boost, or do like v8 rumble power and low end torque?

In the end moneywise I think your gonna be in similar ball parks so just build what you want.

[l314ckhe4rt]

OKAY COOL. i did some research and it seems that the 2jz is more expensive. stock for stock i think ls1 is better but fixing both cars up i think the 2jz has more potential and more expensive in parts and such. ls1 seems simplier because its all motor don't really have to have alot of brain works done to the car.

[OutToWinPAHC]

It depends on the power you want to make. 500RWHP is easy to obtain on both, at less then 3000 lbs its gonna be fast as hell. If you go to high on the HP scale your going to loose street ability.

But stock bottom ends they can handle similar power, but if you were going for a high boost build over 800HP on the 2J or 600 on the LS1 boosted your going to need a bottom end.]

My roommate is a Supra guy and I am a LS guy. And I know the price for his 2Jz parts. Which are quite high and sometimes shocking. But realistically your car is going to be between 2500 and 3000lbs if you build either for 500HP its going to be scary fast. So its just a matter of what you want. They are both cool as hell and I wish you the best of luck.

thanx.

hey since you are a ls guy just wanted to ask if i decided to buy a bare block and build an ls1 motor what are good internal parts to go with???i have seen something about "comp" is this a good name brand?

[OutToWinPAHC]

Comp cams os a good company. They make FAST which make after market intakes, TB's and some injectors, but comp is a valve train company.

Check out LS1 tech.com and see some of the builds out there. But if you get a good LS under 60K not beat to death with heads, cam, intake and TB with supporting parts you can make 500 RWHP no prob on the stock bottom end.

If you get a short block and build I would go stand alone ECM, maybe stroke the motor to 408 but eagle, manley, and JE make great bottom end parts. And there are many of heads available for whatever you build just set you goals and talk to some guys.

dude why not look into a 1jzgte?

im in the process of putting one into my s13 as we speak. i got all my engine, trans, ecu, map sensor,ignitor harness for $1800 now i just need a driveshaft, mounts wise i will be using TWO driver side KA mounts yes it works, you notch the subframe and drops in. same as the factory 240sx x member, cut it and weld the trans mount into it. the 1jz are very stout motors most parts are available at a auto store becuase they cross with 2jz parts you can make 400 all day with the 1jz and not miss a beat.

[OutToWinPAHC]

Well why not a 7MGTE they are much easier to find, also a turbo 3.0 with many US side parts available. My roommate runs Philly supras and he has one and his buddy makes 600RWHP all day on it with less then 8000K into the car.

[l314ckhe4rt]

sorry for sounding stupid but a 1jz and a 7mgte? i know a 1jz is an older supra motor what is a 7mgte? these sounds cheaper something i am very interested in. let me in on the info

[Flicktitty]

2JZ FTW! but look at spending about 8-15K on doing a GOOD 2JZ Swap. i don't know how much for a LS1 but it won't be cheap either.

[OutToWinPAHC]

a 1JZGTE is the JDM turbo engine from a MK3 supra, its a 2.5 Liter twin turbo bu tthe stock turbos are crap and most get converted to single.

The 7MGTE is the 3 liter USDM Turbo MK3 motor. Can be had super cheap and can make big power. The engine used with a rebuild (machine shop) and bottom end would run about 3500. Then upgrades from there.

The 2Js are awesome but the GTE motor sets cost alot. The one JZs are good motors, but since they are J spec parts are harder to come by. The 7MGTE (not 7MGE) is also a stout piece which is cheap to be had and has a lot of potential.

Tonite I was in a 7MGTE supra on the way to the track, then in a 1JZGTE on the way home. The 7M was much more fun.

I BET TO DIFFER...

Generic EBAY Search for: 7mgte engineGeneric EBAY Search for: Aristo 2JZ

Based on Power Goals, yes the 7MGTE is probably going to fit your bill, assuming you want a realistic amount of HP (350-400hp range)But for the price of all the part needed to be replaced for the 7M to hang with the 2JZ it isnt worth it.That plus the 7MGTE has a HISTORY of headgasket problems.

Save your self the time and effort and put a 2JZ into your S13 and with a stock engine you can run 500hp all day with out touching parts...(EXCEPT: Fuel system and you will need a boost controller)

No offence to OutToWinPAHC, but that is really bad advise

[l314ckhe4rt]

okay school me alittle. if i do a 2jz how much u think i would need? money wise. i know an aristo engine runs 1800 shipped then i would need the r154 transmission with 1j bell housing 1j flywheel don't know how much this part would cost. swap kit 1500, intercooler kit 650 , radiator 450, wiring harness shipped out for PNP for transmission. what else.... how much do u think i have to spend even if i do all my labor?

[styc]

cut out the 1500 swap kit. if you have or know someone with a welder you can make your own motor mounts. you can still lay power down with a auto 2jz. i am sure you can find a fmic for less than 650.

[OutToWinPAHC]

No I know of atleast 12 MK3's no head gasket problems some of which are over 450WHP on the stock bottom. But soon to be building.... also with 64MM of turbo

I have seen it allFrom $10k+ swaps to $5k

It all depends on if your doing the work, what type of parts you NEED to buy and which parts can you fabricate ect...

- For the mounts go to Rukus Racing $400- For the radiator buy a 2-3 row SR and have a welder relocate the mouth for you - For wiring (as of now) I only know one place... Pheniox Tuning- You can BS your way through an "intake" - For the exhaust part of this you need to send it to a shop of maybe do it yourself. I would end up sending it

For me my estimated budget is about 7kFor other is could be higher or lower

Good stuff!I KNOW the 7Ms have HG issues but I guess your buddys know what they are doing

[l314ckhe4rt]

well guys there it is. i went with the 2jz! i bought an aristo motor supposely have 40,000miles with an auto transmission for 1700 shipped. don't know if i got an good deal but it fits my project bill for now. now i need an 5 speed from a 1jz. you said ruckus have motor mounts?

[RCA]

Yea contact Ruckus RacingIDK their contact information though.I would do a search on NICO and Google for them.

Also for the transmission...It doesnt HAVE TO be from a 1JZThe transmission you need is called "R154"

R154 is a 5 speed transmission that came in the 1JZGTE Supra AND the 7MGTE Supra.SO the rule of thumb is to find a 1986-1992 Supra turbo 5 speed transmission.

If you get the Supra turbo 7M R154 then you will need to pick up a 1JZ bellhousing and a shifter extentionIf you get the Supra turbo 1JZ R154 then you will need just the shifter extention.

[l314ckhe4rt]

can't find contact number for ruckus racing. maybe there out of business. do u guys know any other place i can find motor mounts and transmisson cross members? what radiator do u guys use?

They are definitly still out there...Your not looking in the right location!

Try searching in zilvia.netI know Ruckus started a thread over there

Also for the rad...Use a SR20 2row-3row and just ask any fabricator to move the top radiator mouth 2 or 3 inches to the center of the radiator.Dont buy Tech2 stuff, they over price things
