After searching for about an hour, i still don't have the answer to the question i have been looking for.

I am planning on getting my se's engine rebuilt with a street port. Being a power hungry guy that i am, i want to also put a turbo on this engine. The only thing thats bothering me is the fact that the older 13b's have a high compression, and i don't want to spend the cash to rebuild the engine, just to pop it.

Has anyone done this to a stock block? How did you do it, and what kinda results have you gotten from it? And of course, any advise from the Guru's is appreciated.

why don't you just buy a J-spec?

i hate to respond like this, as i hated it when ppl said this to me:

It isnt worth the trouble. Although i have never done this myself (turbo'ing the 13b 6 port block), i was planning on it for quite a while. After loads of research, i discovered that it WOULD, in all actuality, be easier/safer/cheaper/FASTER to do a TII swap.

But to answer your question, i have heard that the compression ratios of these rotaries doesnt matter much, as there is not that much diff between the high and low ones. Just odnt drive your car like a maniac.

If you would like more information on why i shunned away from the 6port turbo, please feel free to PM me.

You could easily boost your N/A block.
It's a tried and proven combo.

If you go blow-through, then you can have the whole thing done in a weekend.

I've said it before, and I'll say it again. If I hadn't gotten such a good deal on my engine, I would have gone blow-through turbo on the original SE engine.

dollar for dollar, blow thru will save you big money while making the turbo swap much easier and less expensive while getting great performance! the worst part of turbocharging a na motor is the steel chunk that needs to be ground down to make the turbo 2 exhaust manifold fit! some people make spacers too

Alright, im going to see if im lucky and can get spoon fed, but how would you do a blow through?

I looked at that also. I would not turbo the high compression SE. IMHO your motor will not last very long. Thats why the TIIs have lower compression rotors. Even RB recommends 8.4 ratio. Get the RB catalog and read the section on engine internal mods, this will help improve the engine lifespan. The mods that come to mind are increased fuel pressure, coolant passage porting, street port, grooved stationary gear set.

I'm in the process of doing the TII conversion. Don't get me wrong, it's alot of work, but you'll get a turbo system that works and will last a while (hopefully 100k). I plan on removing the OMP and running premix in the fuel and synthetic in the engine.

If you do go with high compression, try to limit the boost. Also, you'll need a new ECU system, fuel only, since the SE uses a distributor. The SE ECU is not made to handle boost or the higher fuel requirements.

If you want to pass emissions, the TII is also a better route. I don't have a choice.

Check the TII sticky and there is a guy that already did the 6 port turbo.

Good Luck
