Lightbulb Put a turbo please....

Hello guys, I had post a comment about 3 months or so about my coolant seal being blown due to bad tunning, by my ex-shop which i will never go or recommend anyone to go to. Instead of rebuilding I am thinking on spending a little $$ and put on a Turbo engine. To make this short i going to order a J-spec (3rd gen) with the turbos for around $2500. Once i have the engine here are my questions. I will use a stand alone computer Haltech.

1- For the intercooler i should use the upgraded one for a 3rd gen and adapt it to my gen as well as the piping.

2- Which differential is stronger the 2nd gen TII or the 3rd gen.

3- The body that am going to be using is the one for my 90 GXL which is in great shape and have owned forever and don't see the point on buying a TII or 3rd gen if i could get it done to the car, and besided MOST 2nd and 3rd gen that are for sale are pretty wasted and have coming problems, and will cost more to put in the shape that my rx is.

With that can i get some suggestions, all would be greatly encourged.

Regards to all

Well... the mounting points are different from the 13B and the 13BREW, so some custom fab work to get it all to fit will have to be done. Maybe someone makes mounts for this swap, I don't know.

1- OK

2- If I remember right the S4 TII is the strongest

3- OK

Do you plan on running the stock twins?

Well I plan on rebuilding my car and after research to make big power and not as hard install as the rew.. Get a 13b-re you will need to buy a engine mount that is made for the 3 rotor 20b but from what I have looked into it works....for the drive train I'm going to rebuild the TII stuff for the power I'm looking to make. But right now I'm still on the research stage and haven’t figured out if I want to custom make a twin turbo set up or go with a big single turbo or what ecu to go with. But do some research on this board or on other sites. Know age is the key to success of an engine swap (in most cases).

Why not just get a turbo II engine? The swap will cost at least 1/3 of what a 3rd gen swap would. After all is said and done you could have a more powerful TII motor for less money...

I'm looking to put on a 3rd gen. I would do the COSMO but i want to get at least 230hp when am done and it would be easier to get that from a REW. Am still looking and researching on the engine, but by far right now am most interested in the REW. I had totally forgotten about the COSMO, but i will keep that in mind. I want to get it right because i will start investing by december. I already have a the TII engine on. I first want to get the egine and then start looking at the intercoolers. I was looking at the Greddy 24-24R 32R front mount intercooler kit here is the link. http://hopupracing.com/grfrmoickit9.html.
For the ECU am planning to use the Haltech E6X - Flying Lead Kit. I just want to get it right for the engine, guys undertand what i mean right?. In the mean time i will also run in the stock turbos until the following summer or so. Thanks for the post, and Torean the COSMOS is a very good alternative since its cheaper than the REW.

I have a small question. Why not instead of buying the cosmo or the 13b-REW, why not just simply rebuild a S5 TII engine? Just do a rebuild with a streetport or larger and you should easily hit 230hp with the other mods you wish to do, plus maybe e bit more.

Well my car is an N/A so i would still have to buy the intercooler and ecu. If i were to buy an S5 T2 would be cost me around the same and will not be around the HP that i am aiming for. Good question didn't think of it. Right now i got 2 prices for the engine. I found the Cosmo for $850, but forgot to ask what came with the engine and i found the REW for $1950 with the Turbos alternator and every thing esle attarched. Am still probing and looking for advise. I already have the suspension, TOKIKO illumina adjustables, racing beat springs and sway-bars and the front and rear strut tower by corksport. Is now about the engine $$$...

Yeah...thats how im gonn abe come next spring...ill have everythign but the rebuild. But 250 is an easy number to achieve for any turbo car. its all basically in how much you wish to spend. the same 2grand you spend on the 13b-rew can be spent on a rebuilt TII...which you never know teh shape of any rotary when you buy them used....my newish NA had been prev taken apart for a water pump fix and they screwed it u, still ran and everythign just need to do a comp test to see if it was worth my 300 then 150 for the fix.

You're really going at it all wrong...

The motor will not drop in...it will require a little welding and a cross bar/brace (if I understood correctly).

The motor will cost you twice what it will cost you to do a TII swap and get that power, and 3~4 times what it will cost you to do an NA-t setup for the power.

How can you already have the TII Engine but have no ecu and intercooler and then state its an NA? Do you have a TII or not? If you do, then rebuild it. If you don't, the Intercooler doesn't cost much, only $50 for a used stock. Corksport has a FMIC for $250. A used Ecu costs $100 or so on here. You not typing it out clearly so its a little confusing. BTW, with the right tuning and parts, a TII Engine can still run in the same ballpark as the FD motor. If your talking about cosmo, then go ahead, but good luck if you ain't rich. This is what I spent on my setup for my 90 TII. all aftermarket parts are brand new.

HKS Intake -$125
HKS Blow Off Valve - $285.04
Koyo Radiator - $294.99
HKS PFC F-CON Fuel Controller used off ebaystores(still many left) - $175
HKS Fuel Cut Defensor - $85 shipped
Black Magic Electric Fan - $208.83
2.5" Downpipe and straight pipe - $125
3 Gauge Panel on Stereo - $53
Autometer Single Gauge Pod - $30.99
Autometer Gauges: Boost, A/F Ratio, Water Temp, Oil Pressure - $220.02
Corksport Stainless Steel Braided Oil Cooler Lines - $140.61
Mazdaspeed Competition Engine Mounts - $70.00
JDM S5 TII Engine - $877
Total - $2690.48

You will spend more than that on a fd conversion. $2500 for the engine and tranny, doesn't include labor or custom work. If you got the money go ahead and do what you want though. Its your car and dream.

I don't have the engine, and my car is N/A. I'm planning on taking my time on doing this project, and i will take in as many advice as i can. I have the Transmission. CorkSport doesn't have the S5 T2 for $877, if they did i would buy it from them... the FD JDM engine comes with the turbos and i will need them at least for now. Now, to put the FD engine on my FC properly what mods will i need to the engine bay?

Before you mod the engine bay, you'll have to find another turbo.

I don't think you're listening to what we're telling you.


And you don't even need the TII engine or anything. I just picked up a 6-port mazda reman for $500 and will be slapping my turbo stuff on it. That's what you need to do, considering your knowledge, experience and abillity to do research.

Just get another N/A block and make a sound non-turbo car, then turbocharge that. You can do it yourself, or Sonicrat sells an N/A-T kit. I'll also have a twin turbo kit in about 6 months to offer. You really need to find a different road...at least until you've got some more experience. Hell, what you're doing isn't even remotely the best route for your goals.

a friend of mine made a custom motor mount for a 13B-REW in his S5. Stock twins and the FD downpipe all fit. i'm sure he's make another one for you. just email me about it. i'm not on here a lot.

There's no advantage to using the FD or Cosmo engine for what you are doing over the S5 TII engine. For only 250HP, the S5 engine will be fine. And a hell of a lot less work to make fit.
