Intake and throttle body opinions

Hey, I'm putting together a basically stock 6.0 with some bolt ons. Going to throw on a set of LTs and an intake and throttle body. Looking at the 96mm professional products intake and the 92mm jantzer throttle body. Any opinions?

Use a stock LS6 intake and port and polish the TB.

Haven't heard much about the professional products manifolds. For a stock 6.0 and if you have the money go for a F.A.S.T 92MM and the Nick Williams 92MM TB but if not just go with an LS2 manifold and a LS2 TB but I guess it depends on which heads you are using. If your not using LS2 Heads and your using LS1/6 heads just go with an LS6 manifold and ported TB.

I thought ls2 heads were basically the same as ls6 heads.

Some LS2 heads are retangular port while LS1/6 are cathedral port

if you have the coin....the FAST setup will give great power gains on the 6L

other than that...i'd stick with the ls6 intake andported TB

I thought the rectangle ports were only ls3/l92 and ls7?

Never heard of an ls2 with a regtangle port.

This is incorrect. Factory ls2 heads are cathedral port and ls3/l92 heads are rectangle port. For a budget intake ls6/p and p tb will be fine. If you can swing it FAST 92/92 would be great.

Most of the guys on this board either run Fast or Ls6....I chose PP 85mm Intake w/ matching tb because I didnt want the stock look of the LS6 and I wasnt paying the Fast's price tag.

Also forgot to mention something...also gunna be cammed if it matters any...not really wanting to fork over the extra amount of money for what would be a minimal gain. Unless I've read wrong, I've seen where the fast 92/92 setup gains 21 hp over the ls6 intake and the PP gains 17 hp over the ls6. Plus the PP comes with fuel rails crossover, and some fittings. With the fast stuff you have to buy that on top of the 1200 or more price tag, correct?

I think those numbers look a bit high. Depends on the mods to the engine. Regular ls1 fuel rails will work just fine with a FAST.

Stay away from Jantzer TB's would be my suggestion. We offer a Wilson 95mm that would be better.

All Jantzer did was take and copy an inexpensive unit and did not even copy it correctly. Nothing but idle issues resulted from an improperly machined IAC port as well as sticking blades due to material selection and machining. It was a poor copy by somoene who is not an engineer and did no testing, all he did was steal someone elses design and then produced a poorly working version of it.

Yea the 17 hp came on a heads/cam car and most of the gains were up top... a few guys swapped there ls6 for the pp 85mm and saw gains...thats good enough for me. On a bolt on car it wont make much more power then the LS6.

All do respect i know the guy has a bad rep here but do you really need to be an engineer to port a tb? I know more then a few guys running his tb's off of ebay that are very happy.

He wasn't talking about porting a stock tb was he, I thought he was looking to buy a 92mm ? And yes I even had an issue with a few customers with some of his ported tb's and sticking blades as well. I sold his TB's and ported TB's for a while I am very aware of the issues with his stuff as well as the dishonesty involved with him.

i'm a BIG fan of the FAST intakes.

i tested it myself and got what i considered huge gains.

i got it used with a FAST tb and $300 worth of injectors for $1200 shipped. it was even lightly ported by LPE...i ported it more at home with a dremel and 2hrs of time.

on my cam only/bolt-on car....i swapped out my ls6/ported TB for the FAST ....it was tuned before and after so the A/F was consistent...done on the same day, same dyno (never unstrapped it, swapped the intake ON the dyno):

18hp and 12ftlbs
5-10hp and ftlbs from 3000rpm and up...NEVER lost power even down low
moved my peak torque down 500rpm

engine peaked at 6400rpm...not what i would call a "top end cam" and it still showed NICE gains

i have no doubt you'd gain 1/2 that even if you were strictly bolt on. it just flows that much better.

as stated above...the extra money is WELL worth it.

all the stock hardware swaps over to the FAST setup...fuel rail, injectors, throttle cable, gaskets (except TB obviously). hell even the stock bolts (except valley cover...and those come with the intake) can be used it THINK, although the FAST includes those anyway.

so for the $1200 you get a direct swap....although a tune may help some cars. i know i was lean after it.

I was under the impression that the 17 hp gain was on a stock car and not a heads cam car since the before output was in the 320 hp area. Was not aware of the problems with those TBs though. Im not much on a plastic intake myself. I know there's the argument over heat soak, but I don't see as how the air is inside the intake itself long enough to make much of an effect. Initial start up would have major heat soak obviously, but not believe it after that. Also, if for some reason the car backfires, I'm not picking up pieces of my intake.

https://ls1tech.com/forums/generatio...oon-print.html Thats directly from the horses mouth.
I have a few buddies that picked up the old fast 90's for 500 bucks...Little port job and a matching tb and you'll be good to go...If not then go w/ the 96mm pp intake and 90mm or above tb. For you guys telling him to run a ls6 intake and pp tb hes running a 6.0 motor not a ls1.

been doing some more digging...anyone know much about the pro flo xt intakes? They claim 30 hp over the ls6, but id have to buy a new hood to fit it under

The first version had some issues that were immediately fixed.

Chris, why don't you let the world know how much money you stiffed Jantzer Performance for. How many throttle bodies did you sell and not pay Jantzer for? You're dishonest as the day is long.

^^Speaking of Jantzer the banned one himself.

I don't lie Scott, your record speaks for itself from the multiple bannings on here to the ripped off PTM design to the failed attempt to copy that design properly that led to many many hours of customer paid for tuning time trying to resolve an issue that would not/could not be fixed due to defective Jantzer stolen/copied PTM throttle bodies.

You have no credibility Scott I gave you a chance and when you tried to rip me off I closed the door and chapter on you. Now your back under what your 9th different name on here? Thats your idea of honesty.
What ever :eyes: go back to peddling your stolen crap on ebay.

You didn't close the door or chapter on anything. We are more successful now than ever. We have a reputation of the best quality and people know about it.

Well everybody in the pacific northwest knows your true colors. You're a joke. Jantzer Performance cut you off as a supplier for non payment and trying to hold 20+ throttle bodies, that is the 100% truth. Your defense was to play your reputation against ours, now that is quite the man. It's all documented info and you might find yourself in court very soon.

We did use the PTM as well as Nick Williams and FAST TB's to design our unit. We made our own tweeks as did the rest of them. If the design was stolen, then so was the PTM and Nick Williams and others. Fast was the only original design.

It's kind of like how you said for us to make a 100mm lid and then when we tried to do it, you said we stole your idea lol. You have no business sense. You're a dreamer and have no business knowledge. Then again, everybody knows you don't have any car knowledge either, you sit there and talk what Eric tells you like you know it. We have a tainted reputation from the past here on ls1tech, we can fix that. Our Ebay feedback is better than yours. You have a reputation for not knowing what you're talking about. When people in your backyard won't buy from you, that must tell you something.

Scott here is one example of your honesty... anyone can do a search and see how you really are

I would just like to warn anyone who deals with this guy to be carefull. If you leave him negative feedback that was justified he will make bogus claims and blame you and make up lies. And treats customers like crap and antagonizes them. here is what I sent as the feedback comment to Jantzer98ss and is smart ass reply

Hopefully you can get your health situation straightend out before you jump into to many sales. I feel that you were just jerking me around on the shipping on the hood which is bad business. I paid you promptly however after the issue of the hood not being shipped I had the money pulled from paypal. After the hood was finally recieved you were paid that day. I feel I did everything on my side to make this a smooth transaction. The issue was on yours the sellers side in not doing what you said you would do. It took me pulling the money from paypal to get you to get the product shipped. I posted the link to the thread were multiple people complained about the same sort of issues with you. All I got from you was excuses and pity me I am sick. I am amazed that you have such positive feedback when you handle your self the way you have and still do. Hopefully this feedback helps others avoid dealing with similar issues in the future.

This is just one example of who you are. I can post many many more examples to show your true colors. Here is another this covers a span of you from 05-08

Internet Fraud Charges 4/1/05 on Jantzer ( renamed )

--------------------------------------------------------------------------------

Well Folks I know this is stickied above but I am getting a list of people that have paid for product and not received, or got product and sent back the cores to not get the refunds.

I have sent countless emails to several different accounts. PM is full here. Tired of being nice and waiting. Pretty much all the same story I have been reading up here.

I have group legal through my work and will be calling to get full info on everything that needs to be done since he does not live in NC. Since for me its less then $500 most likely they will say to goto small claims, but again he does not live in NC so I am not sure again how to do this. Possibly a class action lawsuit so we all can combine and get paid. I will check into that also. (need more then just me for this extreme)

Also since this was done through the mail, I am checking into Mail Fraud Charges. I luckily paid through PAYPAL using my BOA credit card, and will call them to see about disputing the charges. One BAD issue is that by being strung along for so long it passed PAYPALs dispute date limits.

Please email me at dbaxter@baxtersystems.us if you would like to join the list for a mail fraud investigation.

I will keep a list of the names and will email you back once I find out exactly what .the FBI, or local Law requires to move on this. Most likely the normal, name, address, phone, product purchased, amount owed.

Please do not send me ANY credit card or bank info, let the law have that when they ask.

SORRY SCOTT. You asked for it, we all tried to be nice.

Mods I am not sure if this can be link into the detail and appearance, and gp forums since many of the people are waiting there. If so could you please??

( this was also emailed to him so he can't say he did not get it. )

These are just two small examples of you and your dishonesty
