begi turbo and tri point
- Thread starter jayp3
- Start date
Both of the kits come complete with everything and fuel enrichment. The BEGI kit uses an FMU and the Tripoint kit uses additional injectors. Since the price on these two kits are starting to get very similar I woudl personally go for the tripoint kit. Much larger intercooler, the turbo seems to be a very very good unit. and all the construction is top notch. They use a cast tubular manifold whereas BEGI uses a log style which by its very design is very restrictive. Not knocking BEGI but they could have done much better that intercooler they used might as well be an oil cooler IMO. Go with the tripoint kit I believe you will be much more satisfied.
I wish Tri-Point would have put more time into actually advertising their kit and definately make it more available. Once you pay for tri-points kit, you'll be waiting and additional 4-6 weeks for it. Where as once Begi Finalizes the setup and finishes R&D, they should have a lot faster turn around.......Hopefully
I say give tripoint a try as well. Just so we can see what they're kit has to offer. As far as I know, the only tripoint turbo kit installed was on their prototype.
The BEGI kit is a good one. The best part of the first ten was that they were just under 3K. Great deal...
The intercooler is small, yes, but it's fully functional for what psi we're running at. So in that case, it's more of a cosmetic issue, of course unless you're one day looking to run over 270 HP.
The manifold could have been done different, I totally agree, but upgrades are always there, and if Corky put it in there, it was probably for a reason-my bet was cost.
the feul systems on both kits are different. Yeah tripoint gives you two extra injectors, but if any of you have been with the rest of us BEGI owners through our feul fiasco-Corky doesn't seem to believe in the extra injectors (read what he has to say on his page dedicated to the protege kit). He is more of the FPR guy. They're both just different ways of dealing with the feul. More than likely we will be installing the aux feul pump to give us the PSI we need.
It's all very interesting. We've got tons of BEGI owners now on the board. We need to find a Tripoint person!!!!

I surely hope BEGI doesn't read this post, because it will kind of seem like a slap in the face to the guys at FM Protege. To think thay do all this research and R&D into a kit for the Protege and you guys are talking smack about the intercooler size. It's clear that they thought about the size of the intercooler prior to designing the kit and just like Linux said, it will do fine for with the boost that their kit was designed for. I don't think BEGI would send a boy to do a mans job. I sure as hell wouldn't give a hachet to a lumber jack and tell him to chop down a sequoia.
You can always upgrade to a larger intercooler once there is more of a need for cooling the intake charge.

Lets see, BEGI/FM has been tuning Miata's successfully for years, Tripoint builds race cars...that's a tough choice! I don't think you can go wrong with either.
As for problems with turbo? I don't ever plan on running more than 7PSI on a car that won't be mine for 4 years. I am thinking about going with the BEGI kit. But I may get the spoolin starter kit with a BEGI FMU and figure something else out for an intercooler. I will have to buy this in stages anyway.

you may be right about the intercooler and you may be wrong.....remember Tripoint is using a Spearco intercooler from what I understand from Mark and it may be more effiecient than the one BEGI is using. If the intercooler is more efficient than the tripoint kit would be a better intercooler on matter what boost given that they have the same pressure drop ratio. The cooler the air you are pushing into your manifold at whatever psi the better that.....remember....you must.

FM Protege does read the forum
I would be interested to see a tripoint kit. It's always good to see someone else's solutions to a problem.
There have been bad reliability problems with Aerodyne turbos in the past, so that's one reason that we tend to stay away from them. The concept is great.
IC design is more complex than simple size - the design of the end tanks is important to efficiency. It's better to have many short runs than a few long ones - making a long, thin intercooler a bad idea from the start no matter who makes the cores.
As for manifold design, I'm not an expert. Corky is. So I defer to his judgement on what is a good idea. I do know that his manifolds never crack - we sell hundreds of them for the Miatas.
Getting big numbers from a turbo kit isn't that hard. Getting decent numbers and keeping the engine healthy 100,000 miles later is. That's why we're doing so much testing, and it's our priority. We're coming up with solutions to the fuelling issues and the OBD-II. It's not just a matter of sheer pump capacity, it appears.

I spoke to Corky myself a few months back and brought up the IC size. He said what keith just did...more shorter runs is more efficient than fewer longer runs. Period. Plus, Corky tells me that he only gets 1psi pressure drop through the IC, which is pretty nice and efficient.
KEITH: Listen, TO HELL with the FMU. Get bigger injectors and computer control them. Then I'll buy your kit.
I'm willing to drop an extra $1K for the larger injectors and computer control (like a reprogrammed ECU). Is this a possibility in the near future? Cuz it's what i want!

Man don't listen to Kool, he's been out smokin crack(stoned)
If BEGI starts messin with the ecu then there go my hopes of being able to buy a SMOG Legal turbo kit.....out of all the kits that are out, and the one's coming out that we know of, this is the only kit that has a shot of being approved by CARB.
Keith keep doin what you're doin and don't forget about all us out on the west coast.

With the Miatas, we have both FMU 8 psi kits and ECU-controlled 12+ psi kits available. I would not be surprised if we ended up with the same sort of split on the Protege as well. By the way, the price differential is about $1200. We will definitely be bringing the current FMU setup to market.
However, remember that the Protege platform just isn't as capable at handling the high power as the Miata is. We'll see what happens as we develop more power. It may be that running 12 psi is just beyond reasonable limits.
