N/A to T2 adapters availble soon!

Yep that's right boys and girls....the first run set is done... 2.5 inch spacers to help in the install of a T2 manifold on a N/A block are going to be availible june 11th to SHIP! After slaving away i finally got the first run complete and are currently testing on a N/A rx7. The final product came out looking VERY sharp and I kept the cost very low considering the quality...Pics will be availible soon and the parts will be ready to ship on the 11th like i stated earlier, Intake adapters for turbo swaps or just to put a custom intake on the car will be availible on the 11th as well.... Just thought i'd let you know that these are done and availible, I will be custom making them for whomever wants them....I made a first batch of 10....after that it's all made to order. introductory pricing is in effect.... Thanks for your great brainstorming that let to this project....

This is sad, I just made my spacers and TB intake part.

How much are you asking for them? And what about intercooler piping to a stock T2 FMIC?

Double post

P.s. Someone did this before and it there was much talk, but no one actually went though and bought it. It was really reasonably priced too.

Why will your product be better?

The spacer costs $108..the adapters are $50, they go on the tb and get rid of the ugly plastic elbow. I hadn't seen the other spacers so i really can't comment on them....All i know is the tubing i used and the welding work done in between the plates is so heavy duty it wont need additional mounting points or welding to support the wieght of the turbo and wastegate.....just bolt and go.

Keep me posted, I'm usually in the first gen section.... however let those guys know, many are running 13b motors like myself and are wanting to go turbo.

Will this be paypal or other method? Anyways good job and can't wait to see the pics!

When will the NA guys realize that you don't have a piston motor and you can't just bolt on a turbo and expect not to blow the motor.
After you get a standalone, fuel injectors, turbo, manifold, wastegate, some sort of IC, down pipe, fuel pump, and the countless other things you are way over the price of a t2 swap. Minimum 4k Not to mention you are strapping a turbo on a weaker NA motor with a weak drivetrain backing it. I still say if you want turbo power do a swap. I see Kevin Landers rebuilding alot of NA motors in the future.

This entire swap can be done on the cheap....My friend did his complete N/A to turbo swap for a little over $800. THe turbos and wategates can be had for $150 used, He used T2 injectors and fuel pump- $100 used, A starion IC from a j-yard was $35, the exhaust work cost $120, He is currently running no safc, but has ordered one used of ebay,.... the IC piping was the hardest part and was around $90 with couplers. $23 for a used BOV.

VArious hoses and taps and a guagebrings the total up t0 $573 without the SAFC....with that is was around $800, Not too bad, he built the kit himself and it runs great. He doesn't have the ability to put huge amounts of boost into the motor but it has enough kick to sit you back inyour seat. The motor has been holding up well and he has been running this setup for a little over a year....If driven responsibly the motor will last.

But alas, I am not trying to sell the idea of a N/A TUrbo swap, but there are people who are going to do this so i am just making the swap a little easyer for them. I am offering a well constructed high quality part they can bolt on....

The first step to ANYONE who even thinks about swapping a turbo into their NA should do a compression test first!! Save yourself the trouble of a possibly blown motor a few months later - if it has low compression just rebuild it.

Make sure the car runs correctly first before a project like this...it's not a terribly hard project for a pair of good mechanics but it will be hard on your wallet if the engine lets go after a few quick boosts bc it was already on it's way Just my .02

RRTEC I am not trying to give you sh*t but I am just trying to stress the point of EMS. I understand that their have been a few people that have done it for less money but its such a gamble. First you should never use "used" injectors. Just not a good idea. Second you should not use a AFC because it can tune the injectors, but it can retard timing. Then in the drivtrain, have you ever seen a t2 half shaft compared to a NA halfshaft? Night and day. Also compare the trannies. Not to mention if you used Junk yard parts expect Junk yard performance and reliability. I saw a thunder bird supercharger kit on this forum for a NA that seemed like a great improvement without the same risk factor you have with strapping on a turbo.

Why would you think that supercharged wouldn't have the same risk factor? most Turbo N/As only go to 6 or 7 PSI, just like the supercharger. Forced Induction is Forced Induction, it's already assumed you're putting more stress on the drivetrain and engine, it's just weighing the proformance gains against reliability. If done responsably, you can have both. There have been numerous FI'd N/As (if that makes sense), granted they don't run as high of boost as the factory turbo'd cars, but 6 reliable PSI is better than nothing

Bukwild...
What is wrong with used injectors... send them out to be service and cleaned. Change the O-rings and I've never had a problem.

I understand what you are saying about slapping a turbo on an N/A but alot of guys here don't have a place to swap a motor and a shop will charge up the ***. That's why it's cheaper IMO. Besides 90% of n/aturbo guys don't go past the 5-6psi anyway. Shouldn't be big worries. These are hobby cars, if something breaks beef it up!!

For myself this will be cheaper, I have the 680cc injectors, s4 turbo, msd fuel pump and a shop to do my own work. My engine is a 13B with 3mm seals and it's rebuilt, it is a first gen GSL-SE with a solid axle rear end. My tranny might go if I acheive pretty high hp, but my rear end should be good according to guys that have done Cosmo swaps.

RRtec is offering a great part!

Bah, 6 PSI. Maybe for wusses.

Neat about the adapters, but I still find it odd that now the easiest part of the conversion is available pre-fabbed, but the hard parts are still DIY.

What did you find to be the hardest parts? the IC piping?

My feeling is why try to build up a na motor with a turbo strapped on it for maybe the same performance as a stock t2 motor with less reliablility. Don't be scared to pull out your motor. You strap a turbo on a NA you will have to pull it out sooner than you planned on anyway.
and if you are going to run 5-6 lbs of boost don't even intercool it. Or do you just want the look of a front mount? You know they do sell a intake system that looks like a FMIC.

Hmmmm...seems to me that not intercooling an NA w/ TII manifold and turbo is a very large contributing factor to pulling your newly converted engine sooner than you planned. On most cars yes, this level of boost doesn't require an intercooler. However, the rotary generates a load more heat than most piston engines and heat is the enemy.

A front mounted version of the stock TII IC should suffice for a conversion like this as the unit itself isn't terrible, just placed by Mazda in a terrible position. Also, it's efficient enough to do it's job yet small enough not to completely block the radiator/oil cooler from fresh air in the grille.

Also, 6psi on the NA motor will be quicker than a stock TII any day if you're comparing both cars in excellent condition. The NA motor has higher compression and the 6 port system (provided it works properly) for good offboost throttle response and much better spool than a stock TII. In this respect, the conversion is a better daily car than a stock TII. I would recommend a used SAFC and a new upgraded fuel pump for this project. After installation, a good dyno session with some tuning can net a nice safe, conservative fuel curve for reliability as opposed to maximum power. For a street car, this kind of setup, properly installed and tuned, should not sacrafice much if any reliability of the NA provided all components installed (since most will be used) are in good working order. I STRESS the definition of a street car here with a reliable driver...this means using your new power wisely and not running down the highway on hot days flat out at the top of fourth gear. First of all the speeds are WAY illegal and that kind of stress, abuse, and heat will really strain the motor. Be smart and this setup should reward you

The 6 port system in a turbocharged application is fairly pointless. With the high compression rotors, there isn't really an "off boost" period. As soon as you tip into the throttle, you're on boost.

Also, there is simply no physical space for the 5th/6th port actuators unless you mount them remotely and connect with bicycle cable.

Great input fella's.... I am going to work on IC piping durring the summer to try and come up with a basic kit. The only problem with that people are going to use different FMIC's...BUt at least I may be able to offera "basic" kit.

Is there room for a Air Control Valve?????
