What port do you guys that are running the GT 3540 recommend?
I am going to have Rob at pineapple do a rebuild for me (the engine is heading in his direction right now) and am wondering what you guys think would be the ideal port for that turbo and why.

I think I will be going with the street port but am not sure which large/small or somewhere inbetween.

And why I am on the subject of rob building an engine, what are all the little extras that I should have done in your opinion.
Upgraded seals, oil loopline, cryogen treated internals, others?
Any thoughts on engine upgrades and there value and benefits for the cost.

Thanks

I was jusst talking to Rob in person on Saturday at the Corksport BBQ and Show N Shine, he was explaining to me about about the small street port they do that decreases the turbulence and increases the efficiency with pretty much no noticeable loss in the low end, for a GT35/40 I am sure this port would be great for driving on the street, the performance gains are going to be small, maybe 10-30HP, but the spool up time on the low end should be great, however the GT35/40 spools up so quick anyways, you can go with a larger port and it will still have good bottom end. It all depends on what you plan to use your car for, if your driving it around on the street most of the time go with a small street port, if you are really serious and will be doing a good amount of racing do a large street port or a race port.

my motor is being installed right now. i got a pineapple road race streetport. basically, its focused on midrange power, not huge like nocabs, but not small either. i live in the mountains, and have lots of hills and stuff that i love to drive on. so like icemastr said, its all about what you're going to be using it for.
they replace quite a bit of stuff, i got the stage 3 with the loop line, water seals (only $100), and i sent him new urethane motor mounts (from rotorsports-new design).
if you're gonna do it, i figure, do it right the first time. just chat with rob about what kind of driving you will be doing, he'll recommend whats best for you, and your goals.

And this is why I am asking!
I would like to hear it from people that have nothing monetary to gain from me rebuilding my engine, just want info from helpful people that have been where I am now and have the experience to inform me of good investments and bad. As a business there MO is to sell parts and services to make money, which they do.

OK so the Cryogenic treatment is out

Its amazing what these kids will believe, isn't it Chris?! Im not cracking on anyone, but it pisses me off on how much we get ripped off by **** like this.

rex u.k

whats a stage 3 oil loop whatever?

H2o

Funny how you always seem to be ripping on Pineapple every chance you get, It always amazes me how some people have to try to make the more established guys look worse to make themselves look better.

Mr rx-7 tt

iTrader: (5)

Wrong, most of that post is generic info and is applicable across the board, but as far as the cryogenic stuff:
1) Show me some other "established rotary companies" trying to sell cryogenic oil seals, etc... Please tell me what % of engine failures are because of bad oil seals (not the rubber o-rings)? It's snake oil Pal...

2) I will rip into ANY shop that I believe is doing something that isn't "kosher" to rotary owners that don't know any better. If you want to be believe the cryogenic and other bs have at it, but others here seem to be more open minded. They would like to know where their hard earned dollar is going.

3) Make more established companies look worse? Big hint for you, Pineapple isn't some huge corporation with a monopoly, It's a small little rotary shop just like any other. (KDR, PFS, PETTIT, etc.) and "need to make myself look good" why? This is comical in itself...

4) I have praised Pineapple as well and I have even sent them business.

Exactly...

I dont see any cryogenic treating options on pineapple's website?

paximus

iTrader: (1)

i didn't think they did any cryo stuff either??

H2o

And how does established have anything to do with size, all those companies you listed are all well established yes, are they large corporations?, no, thanks for the hint but learn how to read, and I wasn't refering to the cryo treating half as much as I was to you ripping into Pineapple on two seperate threads, and going on in the one about how good a builder you are, talk about misleading, with all the halfwits that run around on this forum and believe everything they hear you sure could be putting yourself in a way to be looked upon in a better than "___" kinda way.

4) some of my best friends are "_____"
sound familiar.

Mr rx-7 tt

iTrader: (5)

I guess you don't comprehend well...
1) Size usually does matter when talking about being "well established". Bigger shops do more business and have a larger customer base? The larger you are the more established you are, basic econ 101. Also, why you are at it tell me what I do and tell me how "established I am as you seem to know, right?

2) I find it funny how it's "I am ripping into Pineapple every chance I get" to "two threads"...LOL
As far as reading comprehension goes you would notice those statements were generic...that means it refers to ANY shop. Do you understand that concept?
Please show me in that thread other than cryogenic crap where I have specifically stated Pineapple?

3) Maybe you ought to rip into these other guys who made comments about Pineapple?
https://www.rx7club.com/forum/showth...32#post2004532

4) I get e-mails all the time asking questions about rotaries etc. and I always help when I can. I could care less how some little kid like yourself (that knows didly) views me.

5) Lastly, I will say what I want to who I want whenever I want, got it?

Supposable the front bearing is benefited by routing a line to the front bearing recesses from the oil passage (near the filter) to aid in better lubrication to that surface from what I understand.

Is this a necessary thing for a street driven car putting out around 400 HP and realistically not expecting the engine to last to the 100k mark or far beyond?

So please inform me of my follies.

What in your opinion should I have done to have a good reliable engine Mr rx-7 tt.
Are you suggesting not going with pineapple?
Do you feel that there is a better location/business that could serve me better?
Pineapple is very close to me, so any problems wouldnt be a very big hassle for me to talk to him personally and get things straitened out.

talking to my little local rotary group here I don't believe there will be a problem though!

After reading through a couple threads though, I will be requesting that Rob is the actual person doing every bit of the work himself regardless of how long it will take.


What is your opinion on the oil upgrades:

Windage Tray / Pan Baffling
-10 oil lines
Increased Oil Pressure
17mm Oil Pump (stock in some applications)
Oil Pump Cavity Port
Enlarged Oil Passage
Loop Line

what about the lightend rotors?

thanks

I just went to visit Rob today. He said he has been burnt out lately because of all the work thats been coming his way. BUT, he has devised a new system to help prevent this situation from happenning in the future. He's also aware of the concerns from customers regarding quality and this new system that he has will help insure it! When it comes down to it, I would have PINEAPPLE RACING build my motor ANY DAY!

Not that it matters but you are way off base on this one, he's in his mid 30's, built, installed and tuned more motors than I can remember as well as does some excellent fab work.

Another small opinion here...

My engine was rebuilt by Rob with Stage 2 oil mods, a mild-street port, and with autoX and street use in mind (what I discussed with Rob that I'd be doing).

Engine is still purring, pulling really strong all the way past redline, giving unbelievably linear power, and pushing ~380rwhp with an RX6. With bigger injectors I should be at right around 400.

I have nothing but great things to say about Rob. He was friendly, patient with me (a guy who didn't and still doesn't know a ton about engine rebuilding), and very straightforward about things he believed that I didn't need for my particular application.

I shipped my engine a long, long way to get it rebuilt by him and I'd do it again if I ever bought another rotary.

My op.

Oh, also, unless things have changed in the past couple of years (which they may have), Rob builds every engine himself. Has that changed?

Being established has nothing to do with size, and everything to do with profitability and stability over a period of time, Don't need econ 101, my family has been in business since 1897, we have 10 employees and oh yes very profitable, as for what you do it's irrelevant I never said I know what you do, just what you imply.

It wasn't stated it was implied, the comments may be general but sure are pointed in that direction.

Everybody will get there chance don't worry, and it has nothing to do with Pineapple, and more to do with people who feel free to rip into vendors, as if they are never at fault themselves, be it Pineapple or whoever.


4) I get e-mails all the time asking questions about rotaries etc. and I always help when I can. I could care less how some little kid like yourself (that knows didly) views me. [/QUOTE]

This proves my point exactly, who are you for people to trust any more than they should trust Rob, or Dave, or Cameron or whoever. Yet you seem to make it known for all that you've never had a engine returned, as far as me being a kid you couldn't be more wrong.


5) Lastly, I will say what I want to who I want whenever I want, got it? [/QUOTE]

Yes sir.

Chronos

If you still have time, CANCEL THAT LOOPLINE!!! Unless you plan on taking out your P/S and A/C, the loopline is useless. They drill two holes in your motor (when my shop fired up the engine all the oil squirted out!) and even if you plug them up with a bolt (better get the thread right or you'll cross thread your block!) you still can't have the A/C and P/S because they won't sit flush against the engine with the bolt sticking out! I learned my lesson...DON'T GET THINGS YOU DON'T KNOW ABOUT JUST BECAUSE THE OPTION IS THERE!

The only you could do is make a custom bracket to hold for your A/C and P/S to the right and have a hole in it so the loop line can go through. If you can't immagine what I'm telling you, then DON'T GET THE KIT! Luckily for me I was able to plug both holes up with a special nut with an indented area for an Allen wrench so it sealed the hole and was flush with the block, allowing me to put the A/C and P/S back where it should be.

Call Rob and talk to him about it ASAP!

Chronos were exactly is the loop line located?
Is it on the front plate and located under the ps ac mounting plate?
I am very capable of any modification necessary to make the loop line functional if it is worth the effort.

I just need advice as to which things are worth the money invested.

Obviously you would have made it functional if you found it beneficial, or had the capability to make it work.

Did you forgo using it simply because you found out when you received your engine that it did not work with the ac and ps without modification?



Does anybody have any experience with the lightened rotors?

I was just holding one in my hand today marveling at how heavy they felt compared to there inferior counterpart the aluminum piston which felt remarkably light in comparison when held next to each other.

I cant help but think that it would be very beneficial to lighten those rotors down if possible. How beneficial is it to lighten rotors knowing that rotational inertia can rob a lot of energy

And thanks to those that are staying on topic and for your incite and help to the questions I have

Chronos

I just didn't want to invest the money and time in fabbing up a custom bracket since we found a quick and easy remedy to the situation. I am glad, however, that I did get the loopline kit because even though I have no use for it now, I will later when I'm running significantly more power with the GT35/40.

The holes drilled into your block are located on the right side just to the left of your A/C and P/S.

Badog

All you need it a 90 degree fitting and maybe some time with a RotoZip with a grinding wheel...the stock bracket works fine. You can keep your AC and PS.

Chronos

Yeah, just plan it out beforehand so you're not faced with a situation like I was
