Hi Mike. I'm going against what Dez told me. I just bought a GT28RS kit that was on another 09 JCW. Allegedly was getting 298whp. I got everything except the M7 scoop and waiting for the "map". RMS modified the wastegate and did most of the customization & worked with Jeff at Alta and Cobb with the tuning. Opinions?

Awesome Ray. Aside from having a good name, youre on the way to having a nasty mini.

Good job going against the advice of people that have plenty of experience with trying to get that turbo to work on our motor.

Great it made 298.....have you seen the dyno graph of it? There's so much more to it than peak numbers

You guys are never going to get it..........when will the hard on's for GT28RS's end....

Why doesn't one of you "envelope pushers" try to put a GT3070r on it?

I know Dez had talked to you, but he didn't go into details with me. I'll hit him up about it so I know for sure, but I can assume what he told you would be what I would tell you too. It's a shame we couldn't help out, but I hope your project works out all the same. Feel free to call again if there is anything we can do for you.

I agree 100% on this. Everyone that has integrated a GT28rs has admitted it was a major project to get the exhaust, plumbing, and fitment correct. One top of that tuning was an issue (not so much anymore). Man, a JCW turbo has all the breath the R56 really needs to drive with purpose and precision.

Thumper: You know a 3070 is way too big for 1.6L. I know you are trying to make a point but why is there so much adversity for people trying different stuff? Just because most are happy with factory parts with bolt-ons doesnt mean others are. That being said I do respect you and your experience with these cars. In order for ingenuity to pay off a lot of failure happens. Nobody said you could make 1000 hp on a stock bottom end supra a few years back...

Guys guys guys, nobody is saying you can't fit a Garrett GT2871RS to your factory stock N14 engine, what Thumper, I and quite a few knowledgeable people are saying, is that the larger turbo, simply is a BIG mismatch, and all your doing is introducing unwanted turbo lag, uncontrollable boost spikes and eventual tears!

1000HP from the supra engine, is all at the upper regions of the RPM band, and to produce such HP, you need a oversized turbo, which in turn needs huge amounts of flow to spool it up!

Sadly our tiny 1.6 engine, does not have enough volumetric flow to spool up an oversized turbo efficiently, and no amount of amateur trial and error testing will ever get the N14 engine to run an oversized turbo efficiently!

The N14 engine is very very sensitive to changes, and unless you've got BIG BIG bucks a full research facility, then your simply wasting your money, time and effort, leave it to the professionals, and we will tell you what works and what doesn't.

The ideal turbo is going to be sized similar to the JCW. An N14 with a built bottom end ( MCS comp ratio 10:4 ) and some head work would compliment a turbo of that size very well. This is my goal at least since it should give a good all around platform to work with. Daily friendly, uses pump gas and can be tracked reliably.

Yes I know a 3071 is too big, it was in sarcasm.

There's NO adversity to trying different stuff...except that people have tried the GT28RS and it is less than ideal. It's just hard to convey a point when you have numerous people telling you there are better ways to go and yet there are still people insisting on trying to run a 28RS. Every tuner that has tried it has agreed it is not the way to go.



^^sage advice & wisdom

Agree w/ Mike again...

at what RPM does the stock turbo spool? JCW? I remember around 3K

2xxx, full boost for me (21psi) by 4500-5000

Hi Mike. I had already purchased the kit and then talked to Dez. What he suggests is lower end work. He's concerned with piston issues with this turbo. The person I bought the kit from did a lot of R&D with various tuner shops and allegedly got it working correctly. I bought everything from him. The turbo, entire exhaust, coolant & oil lines, reworked wastegate actuator, catch can, boost control solenoid, all the shielding, intake plumbing, etc. It seemed to work for him. Now maybe it won't for me. Anyways, dez says you have something coming out in the next 4-6 weeks but wouldn't tell me what. I also talked with Dez about extra fueling to get over 300hp. He was talking about a new manifold and additional injectors.

So my next step is to install the turbo kit and see what my results are. I want to see how the driveability is. And power of course. If all is favorable Dez says he can build the engine to turn to 9200 rpm like he does with the r53's. Cost around 7K for just the engine. Of course everything in steps. My goal is to be in the 350-400whp range and have the effective power band between 4000-9000. So after this install I'll have Dez build the engine, my shop will install it. Then I'll have to ship the car to you for custom tuning, exhaust, intake, etc. It seems like the extra fueling requirements over 300whp are still in R&D. Hopefully by the time I'm ready you will be ready.

Robert F. Kennedy had something to say..."Only those who dare to fail greatly can ever achieve greatly."

Please take pics of the aftermath!

I'm new to the forums and my MCS is stock and also failure on 3rd piston. Lucky it was covered under warranty. But I'm looking to build a motor. This sounds great, but what about a head. I've read they're not great. I will be ordering a block soon.

Call up ABF or E-mail Mike above. They will build the head. I called them Friday (the day I lost a piston). I'm gonna pull the engine/head and decide if I need to have the block sleeved or just pistons and rods. I'm being told the Mini is pretty insane at 300whp and most don't want more.

Ray

Looking to build a motor to hold alot more than 300whp, only because I want a bullet proof motor and don't want to spend my money twice. I'll be driving it around with 300whp. I'll be posting pics of build. Just finished paint work waiting on my HRE's. Now comes the motor and etc.... Can't wait. My warranty just ran out!!!!!!

Dez at ABF says they have put 600-700hp through it and it didn't break. He also told me if I bend a rod he would buy the motor for me. We also talked about the head work. Basically ABF can build the motor and head for 9200 rpm which is when the valve start to float. But you will need additional fueling over 300whp. Additional injectors and ECM for extra fuel. And a whole lot of tuning. What turbo you gonna run? GT2871??


Ray

I was thinking the Alta turbo, but not sure yet...

The Alta turbo won't make 300whp. If interested mine might be for sale in the near future.

how much will it make??

WOW have i read that right 600-700hp and 9200rpm from the R56 engine?
if thats right i want that in my car

Do you understand that will cost probably $30,000+ and a lot of dedication and R&D. I think realistically 300-400 is all you can put to the road. I'm being told in the 300's is enough!

and yet I don't think we've ever seen a dyno that showed more than about 250hp...

raymazing - got any old dynos you want to post so we can see 300?

the last dyno sheet i could find was on an old tune and less boost and that one was 252whp on a ***** of a mustang dyno= 287-297whp on a dynojet. the new tune and more boost is way mo betta ;-) lol!

edit: this might have been on stock cams too... they came in and out a couple times trying to get the car to behave.

That number is on the R53. But he said the R56 should be able to do it. Of it won't be streetable.
