Why do people do wild swaps(RB, LS1), when u can just buy a Porsche, Ferrari, etc?

[foodman]

Ah..found these ITBs that are DBW/ETC friendly (drive by wire/electronic throttle control)
http://www.harrop.com.au/eng_detail....99-AMFD7958-00

I little pricey tho at $5k. I keep reading the Jenvey ITBs are actually pretty good, especially for the price at $2.6k if I'm not mistaken (which is dang cheap for nice ITBs in general and for any kind of motor really). But idk if the Jenvey can be made to work with DBW/ETC and/or and LSx swap tho

[foodman]

Snap...I remember this video. I guess someone already did it

I wonder what kinda ITBs are those. Maybe Jenvey? They don't look like the Harrop ITBs. I see a TPS in the front ..idk if it's DBW tho. I think it's cable.

[foodman]

I don't think these vids have been posted yet anywhere in these forums..

...but, IT RUNS!

I believe they're Jenvey ITBs. I read Harrop ITBs would be much easier to make them work, tune and make it much more drivable though, because it's DBW, it bundles all 8 tb's into 1 maf reading and also you don't need to fab and figure out throttle linkages and cables. I think the new big thing now is DBW ITBs and some of the old school ITB companies are starting to develop them. Cable ITBs are old news I guess lol.

To answer my own question...I've read CMS (Cunningham Motorsports) in SoCal are one of the best tuners for LSx engines and also have knowledge in tuning and setting up Harrop ITB's correctly (and perhaps Jenvey ITBs as well?).

And for the lazy and non-diy'ers in cali.. Maybe they can even do the entire LSx swap too I bet if you provided them with the Vorshlag kit and engine, trans and all subsystem parts. Should be quick and easy since the vorshlag kit is bolt on and all the hard tasks of engineering/fabbing would be done already.


As for the Vorshlag Alpha blog..it isn't updated yet..but their SmugMug gallery (which I occasionally look at) seems to have been updated with new pics...showing header design/fabbing.

Lastly, the DriftWorks ae86 v8 blog hasn't been updated either..but they uploaded a new video on their YouTube channel a few days ago showing their new LSX 454 ripping it up drifting..so I guess they got the new engine in and working fine pretty quickly (they had an LS3 first...but they replaced it with the iron LSX 454 cuz they be cray lol ).

@cf6mech:

Since you're using an LS1 now...will it be cable throttle or DBW?

If DBW...are you just using the LS3 manifold, or both the LS3 manifold and also LS3 heads? ..because if you're just using the LS3 manifold, wouldn't the LS3 manifold's rectangle ports not match and be a mismatch to the LS1 head's cathedral ports??

Is another reason you're going LS1 for money savings?? How much cheaper is a used LS1 vs a used LS3??

What are the average prices for a used LS1 and a used LS3? (I'm now seriously considering doing this in the future...but of course I cannot afford a new crate LS3 and wondering if I should look for a used LS1 or used LS3 (if used LS3 are affordable of course)).

Are you using a brand new Tremec Magnum XL? I assume this tranny is the ONLY option that will reach/fit the extremely aft shifter opening in the tunnel, correct? (which I think can be a negative, since these trannies are new and cannot easily be found used like the other standard t56 trannies)

Using LS1 and LS2 manifold and throttle body. FRS/BRZ has a fly by wire throttle so it has to be non cable electronic TB. The big expense is the transmission it seems for this kit. There are tons of options and availability with any of the all aluminum generation three GM engines and the prices are very cheap and can be made to make big torque and HP if one so desires.

[foodman]

Ah...so the LS2 is DBW(drive by wire/electronic tb) too? Didn't know that. So I assume LS2 intake manifold also matches the LS1's cathedral head ports?

[foodman]

Orido's LS7 86 and also the RSR Nascar 5.7l V8 86 look pretty darn sweet too

I wonder exactly what kinda 5.7l engine the RSR one is tho and what makes it a Nascar

Looks like a TRD pushrod v8, the kind the Toyota Sprint Cup cars use.

@cf6mech:

Is Vorshlag also going to set up your suspension in regards to the extra 40-100lbs from he LSx swap??

Are you going to get new coilovers after the swap? Maybe their super nice MCS TT1's?

After I read more into their threads/blog...they really do look like the real deal. Especially as all they deal with are true, real, competition coilover companies like Moton, MCS, Bilstein, etc.

I'd love to see them tune and setup coilovers specifically for an LSx swapped 86, like your car ...but I'm pretty sure it won't be too much different as it might only gain 40-60lbs and probably just maybe diff spring rates, at most and if anything.

[foodman]

I'm aware the average price for a complete LSx swap will be around $20-25k (but using a brand new engine and also including labor). But, do you think it would be possible for me to do this on a smaller budget of <$15k using a used engine, the Vorshlag kit and with me doing all the labor/work?

After reading this product page for the BMW swap kit (http://www.vorshlag.com/index.php?cPath=1_4_63), taking into account most of those possible future parts that may arise and be needed for the FRS build and adding them all up for a Total and also overestimating... in addition to also including extra non-oem parts and also non-vorshlag-unique-kit parts (like aftermarket radiator, clutch, flywheel, etc.), I think the total would be around $8k for the kit plus all sub-system parts.

Then, around $2-3k for a used/junkyard/front-clip LS1 (one including all used wiring harness, ecm, brackets, accessories..which I see many used LSx engines include). LS2 TB and intake manifold is only about another $300-500.

Lastly, a brand new Tremec Magnum XL...for around $3.5k

Which..brings me to a grand total of around $15k for engine, tranny and all sub-system parts.

Does this estimate sound about right for a complete swap using a used LS1? I've overestimated quite high too for all possible sub-system parts.

Do you think this is realistic and doable with this low budget and if I do all the work?

I think I may start keeping my eye open for good deals/parts/engines, hoard and "collect" all the needed parts, slowly, over time...so maybe in a few years when I have finally aquired all the parts, then I can finally do the swap pretty quickly. This way, it would also be easier on the pocket too since I don't need to save up for one huge lump sum of $15k, and I can just buy one part at a time whenever I have the extra change and can afford each piece.

Similar budget as me on previous swaps. As I noted early on the transmission is usually the hardest part for me. Ive picked up fresh lq9s for under 1000 $ and then couldn't finder a transmission that would work under 3000 $ to save my life. Yet somehow my buddy shits a tremec out of nowhere but then spends 5000 $ on an ls6! You just have to get lucky on a budget. My buddy has better luck buying totalled cars and getting transmissions and I usually get junk trucks for the engines. But they all have automatics.

Seems about right , you just have to wait though, my car should be done by next month, then shortly there after I'm sure they will have pricing. I already have KW variant 3 coil overs on the car with higher spring rates.

Here's a good question:

How would you get an LSx swap (or any other custom swap really) legally smogged, registered, street-legal and carb legal in Cali?? I don't think this is possible unless you get a shady illegal smog, correct?

I'm not exactly 100% sure on the carb/smog/street-legal laws in Cali...but iirc, isn't a custom engine swap like this only allowed and street-legal in "classic cars," 30+ year old cars and/or pre-1986 cars???

As I'm aware...it doesn't really matter if the engine has all the emissions controls on it like cats, etc...since it's not the factory engine that came with the chassis in the first place ...so it would still not be street-legal, smog/carb-legal, unregisterable, etc..correct?

Correct me if I'm wrong and explain please if an LSx FRS could be DD/street-legal in Cali ..and if possible, what would be the process of making it 100% street legal.
