So there are 14 studs
thank you for this information.
This kit is full plug and play ?
Yes, there are a total of 14 studs. I bought it for my 1JZ and it works great. I don't know how much the bottom end will hold with Clevites, ARP and the girdle but I believe it will hold a lot. Any comments Dusty?
As far as the 1JZ power capabilities, with your upgrades it will be fairly strong but rods/pistons are a great addition to make the bottom end bulletproof!
Apologies on the late reply sir, my email crashed the day I was sent this notification.
on the 2JZ how what kinda HP will this engine girdle hold?
With a good tune, what do you think the 1JZ bottom end will hold with stock pistons and rods and with upgraded pistons and rods? Both setups using clevites, ARP and the girdle.
Dusty & Robert are at the meet and will be back Monday, they will be able to answer your tech queries.
In stock form we typically will not push a 1J past 450-500. Fully built bottom end and the girdle kit the bottom end will be strong enough for atleast 1000 if you so desired to go that high.
That is 100% correct sir. Here at MVP we do not shoot for making big power when doing customers vehicles. We go for max reliability/longevity. Would you rather make 650rwhp for 12 months or 450-500rwhp for years? It's not that it can't handle power past those levels by any means but like most of us here at MVP we prefer the car be safe and last as long as possible. Even on 2JZ-GTE engines I know Dusty typically recommends internal work after 600rwhp when most of us have seen numerous people break 800 on stock bottom end. All about having a reliable performance car while making great respectable power.
Cool. My 1JZ has Carillo rods, CP pistons, clevites, L19 hardware and girdle. Clearances were set on the larger side to compensate for thermal expansion. What do you think my power level should be?
It's very hard to guess what kind of power will be made. A lot of factors will come into play, fuel setup, turbo setup, boost level, target AFR's, timing, tuning software/tuning and so on and so forth.
Again: A girdle and billet mains accomplish the SAME EXACT THING. You don't need both, its a waste of money. You need one or the other.
$650 + $700 to line hone + $129 for APR Main studs = $1,479 total cost.
$750 including ARP main studs + $0 for line hone = $750 total cost.
Can you please explain to me how this works as well as billet mains? From all the research I have done(alot on yellowbullet) it seems as if most just say that a girdle on an iron block is useless. Do you have any documented customers using this without any issues? I would love to go with this instead of billet mains, but I would need proof before dropping $750 on something undocumented or proven.

You may already know most of what I'm about to write, so forgive me if you do. This explanation is for everyone.
The point of billet mains is to have a main cap that is stronger than the stock main cap. You need, in theory, a stronger main cap because at high HP / high RPM the caps take a beating. This beating is an uneven beating, meaning at any given time 1-2 caps are being hit harder and taking on more stress than the other caps/webs. Billet mains are a tougher material and absorb this individual beating better/longer than OEM caps.
The point of a girdle is to reduce the stress on individual main caps, and evenly distribute it over all the caps. A girdle ties the main caps together and make them part of a team. This puts less stress on each cap/web, thus negating the need for stronger caps.
Some people actually use both. I find that to be overkill, as I have never seen a 2JZ block grenade on a main cap issue that had either billet mains or a girdle. Not saying it couldn't happen, sure it COULD. Then again I could get struck by lightning today.
Regarding people that are using the girdle:
No one has stated any issues to me what-so-ever, minus one customer had a fitment issue with his oil pan. No customer has killed his motor using the girdle.
I have 2 customers in the Middle East making very high HP, one is running an 88mm turbo and the other a 91mm and is in the process of upgrading to a 94mm.
I use the girdle on my Supra but I'm making only 1100rwhp.
Ross Baird / Dynosaur Performance is using the girdle on their white Supra which has ran 8.3 multiple times.
Thanks for the reply Dusty, very descriptive and informative. I tried to look at it on the website but firefox is saying that MVPmotorsports is an attack site....dont know whats going on there. If its not already there, you should add what you just wrote in response as it is very informative and will help others with questions.
No problem Jason. I will add the description in so its more clear to people.
Regarding the attack site issue/error on MVP's website, there's already a thread here on SF about it. Its an issue that is being resolved today, and no, MVP's website is not an attack site and poses no threat what-so-ever. Thanks Google...
What is the torque of tightening on the ARP bolts ???
I have no instructions...
