AMS,

maybe you can start a poll with pricing estimates to more accurately gauge interest in a turbo manifold/turbo upgrade. Thanks for the update

AMS is headed in the right direction with price... Making a poll to gauge what customers wont accomplish much because there is only so much that can be done to cut costs but still have a product that a company like AMS would be proud to put their name on.

A cast manifold is significantly cheaper than a tubular manifold to fabricate cutting the costs in a pretty big way...

Smart move, Eric. Lots of great deals on houses up in the Chicago area. Out of curiosity, why a no-go on the single turbo? Space constraints? Tuning?

$3,000 for a single turbo setup isn't realistic... you can't even get an ATP gt3071 kit for the MKV gti for that price...

I dont kno how u would think a single turbo set up is gonna be cheaper than twins, when the factory has twins?? A single turbo would be much more expensive because you have to R&D an entire new manifold.

True, if they keep the twins all they really have to do is change the flange size and maybe refine the headers a tad.

Well, not necessarily. Larger twins will need bigger intake tubing as well. The stock tubes coming off the stock twins are like 0.8 inches if I remember correctly. Even if you bought rebuilt stockers like ASR I wonder if the intake plumbing is a bit restrictive. True you may save some money on the exhaust manifold but that is only if it doesn't need to be replaced anyway. On the other hand, 1 turbo is cheaper than 2, plus if you are talking "complete kit" then consider the single downpipe, single exhaust, etc.

Yea but you have to understand there is so much more development that goes into a single turbo kit for the car. If you stick with the stock system and use what is provided since the car is already twin turbo, it would cost much more to configure a really well designed single turbo kit. Downpipes are pretty cheap already how much more are you gonna save by going to just one downpipe? On top of all that there is very little space to fab an entire single kit. It can be done but again costs will be higher than replacing it with new twins. Ask Eric from AMS he will agree, talk to him about it before. These replacement twins will make good power on pump gas and a nice power band. From a business stand point the cost of developing a single turbo probably is over many peoples budgets.

We all wish this kit would cost 2-3K, but lets be realistic....

Nice job AMS, that kind of power on pump is definetly not even pushing the limit. Very Good!

For a point of reference, the GReddy kit for the Mazda RX-8 can be had all-in for < $5k.

This kit converts an NA car to a turbocharged car, so it obviously includes a new exhaust manifold.

I think if you guys at AMS can come in around the $5k price point, you'll have the problem of 'too many customers'.

Good luck!!!

too many customers is never a problem, whereas too few certainly is. You can always hire more people, but you can only cut costs so much

'Too many customers' is the problem all businesses want, but not so many can handle if they get it.

I would definitely buy a kit at the 2-3k price point. I probably would not spend more than this. At some point you have to consider whether it is worth it or whether you should save the $ and invest it into your next ride. Doubtless there will be some who are willing to pay 5K, but I think most of the market is not.

It's all personal preference... but a fully decked out 335i... coilovers... LSD... turbo upgrade.. meth... is an AMAZING car that puts you deep in supercar territory and still makes a great/comfy daily driver... for A LOT less money...

I get the 'next ride' part... but IMHO 5k for a turbo upgrade doesn't seem that unreasonable in any way.....

Very true, look at turbo kits for N/A engine conversions to FI... check out kits for say a 350z or G35 for example. They have to replace basically everything but the engine itself (intake, intercooler, manifold, turbos, downpipes, tune, etc.) and single kits can be 3-5k and twin kits are usually 5-7k. In comparison, a kit for our car wouldn't need a tune or FMIC if you already have that... so I certainly won't believe any nonsense as to why our car "just costs more". It's like ASR charging $5k to rebuild your stock turbos... even if it somehow did cost them that much to recoup costs, they spent too much. I mean if McDonalds found a special cow to fly over from another country by helicopter 1 at a time and then deliver the meat in a Ferrarri because it just helps the meat or something... would you be willing to buy hamburgers for $79.99 just because they said it costs that much to make? get real

Yeah, the RX-8 kit came with all the plumbing and IC. There isn't much cost for the tubing, but it took someone a little while to figure out how to do the bends & cuts and then mandrel bend all the tubing.

Given the RX-8 kit came with one very crappy little turbo (Mitsu 18g), I reckon the savings on plumbing, bending, and the IC could cover the 2 Disco Potatoes upgrade from a single 18g.

So, given that the RX-8 kit can be had brand new for < $4k and that GT28rs turbos can be bought at retail for $1k each, it's clear that AMS could bring something to market at an appealing price point.
