Nope Im Looki At Maybe 7500 Totally Done With Abou 380 To The Rear Wheels. And Getting 20 Mpg

Yeah, I remember the conversation and I think I said the same thing then. The problem is not the swap or the cost of the motor. Its everything else that you WILL have to upgrade just to keep the car on the road. Cooling, fuel, tranny, rear diff, axels, ect, ect... I don't know for sure but I don't think those items were included in that quote.

Rocketman1976

It comes with everything the motor will need to run including cooling and fuel setup. Here's the list...

Streetported and Rebuilt 20B Engine
Custom 20B Subframe
Custom Turbo kit (Turbo, Manifold, Wastegate, downpipe)
Microtech EMS
Custom Ignition system
Greddy Front Mount Intercooler, Modified Piping
Koyo Performance Radiator
Custom 4 inch full exhaust system
Custom Dual Oil Cooler Setup
Custom Fuel System with Dual Intank Fuel Pumps
Methanol Injection system
557 RWHP at 14lbs of boost. Will easily make 700 RWHP on high boost and pump gas.

But no tranny or rearend. Still a badass deal. I just don't want to do this much of a change to my car. Although it would be fun to spank my friends Mach 1 that makes 650 rwhp on a built SC'd motor, using a 2.0 liter. Not the same guy I mentioned with the 93, this guy passed the Turbo'd 93 GT when they hit 110 mph.

What about your driver train upgrades? I'm not so sure the RX8 transmission can hold those numbers, nor your differential. Just a thought although I honestly haven't looked into it but it sounds like an INSANE swap!

dznutzuk

Well I picked up the engine for 1450euros and cracked it opened and it had new rotor housings and seals and everything so it was a very good deal since I already have a haltech e6k and new 3mm apex seals from my previous rx7 fd. So I just need a need turbo(probably r85) intercooler wastegate and fuel parts, shouldn't come out to too much since I'm doing everything myself.

dznutzuk

I might be able to find one but I don't know what the differences are with the euro spec rx8's

Rocketman1976

It might handle it if you never went above 3000 rpms, stayed out of full boost, and Granny shifted it, but who would ever be able to do that?

You could get the BHR rear end upgrades, and I don't know about fitment but couldn't you get an FD transmission?

cmr333

lol

Rocketman1976

It is still about engine swaps...

Triperformance

Part of engine swaps is doing the other required changes with the engine which this isn't just a SR20DET swap....its also the transmission and custom drive shaft. The SR20DET is going to make about the same power the Renesis made to the wheels stock so the differential should be alright.

cmr333

this is true....i plan on leaving the sr as stock as possible for now just so i can get used to the charicteristics of the car after all this has been done. the rear end will be fine for now but as with the 3 rotor swap when i get more power, a new rearend fuel and all that good stuff goes out for somthing that can handle it.

Triperformance

Nice, I'm sure you will love the SR way more due to the fact that is is better on gas and has a pretty strong torque curve. My buddy has a completely built s14 blacktop and is putting out 303 and around 295 f/lbs torque at 6,000 rpm with 15 lbs of boost on the factory turbo(15 lbs is the max flow). The issue is he didn't have any way of tuning it so he was detonating and couldn't get to the planned 7,500 rpm's he wanted. Hes going to pick up aem ems and could find some additional 40 or 50 hp out of his car. He has full boost at 2,500 rpm's and it pulls hard. Anyways Keep us posted and enjoy the SR!

rgonza

One's of most problem with this engine is cant handle high boost with pump gas start get detonation at just 14 psi of boost, i think is better option go for 13B REW from cosmo with just 15 psi boost you got about 500 RWHP on pump gas with street ported ports. On 20b there's another story with just 14 psi you got about 689 RWHP on GT45r turbo on pumps gas and long reability mine runs about 4 years on the without any problems, Now this car is on 930 RWHP on pump gas and water/methanol injection system. and it still run in the streets like factory does.

Rocketman1976

Thats because Rotary is kick ***

Making 689-930 hp with a 2 liter, most other motors would have to be some track motor that you don't want to drive to work...

cmr333

i agree that rgonza's 8 is friggin bad *** and not to be fu*%ed with. he has my respect hands down, but he gets like what 4.5 mpg lol gas is way not cheap. in the future though i plan on giving this sr the works in the way of turbo, engine manament, and massive fuel upgrades to make alot of ponies to have fun with. as for now i just cant wait to get my baby back so i can park my accord (beeter) lol

There are 13B's pushing more than 800whp. There are more out there pushing more out there but it's quite hard for a dyno to clock in the right numbers. You're in PR, i'm sure you know what i'm talking about .

Rocketman1976

4.5 mpg isn't much worse than a renesis stock

I guess I helped fund a small part for you! Private investor checking in

cmr333

so now its all about grinding powder coat and setting up for the new fd rack, and custom tie rods, and ends. lol damn eps, i loved it when i had it and wanted to keep it....but with this kind of things sacrifices must be made to get somthing differant on the road and safe.

FloppinNachos

I'm pretty sure the rx-8 rearend can handle an sr20.... it's not that powerful of an engine.

The turbo rx-8s aren't required to upgrade the rear end.

angeljoelv

Listen to the master.............. His 8 is CRAZYYYYYYYYYYYYYYYY!!!!!
It was my inspiration...

Rocketman1976

What was the approx total cost to get the 20b setup done and streetable?
It is the ultimate upgrade!

well another big reason i can see going with the SR over a rotary, is becasue of knowledge.

its much easier to call up a nissan guy and say i can't figure out why its doing this and they say well you have to do this

but with the rotary it takes a specialized mechanic to work on it and a really expensive one if you want it to last, thats the reason why its cheaper to work on piston motors is because of knowledge, there is just alot more of it versus that of a rotary
i'm swapping my rotary out for a piston motor, becasue i want something familiar under my hood, and i don't have the money to blow on learing and experiminting with a whole different kind of machine.

now i love rotarys, and have tons of respect for the people who build them, but personly i don't know nearly enough about them to start makeing big power with them. but i have built several 300-400 hp SR's and several high power inline 6's
(RB's and 2J's)

sixgen3sgte

and i have driven a 800 hp 20b rx7 and i would not want ot drive it to work, i want somethin i can turn the boost down on and get 20 mpg but then crank it up when i see somthing i want to run

tajabaho1

nice man, its a very good powerplant, 2 of my friends drive s13 with sr20 in them, even though one caught fire due to electrical wire spark, its still a great powerplant
