D1 WTF

can any one tell me how much work is involved in putting in a 3 rotor engine.  

i know the inlet manafold etc

but more structurley
do the engine mounts have to be moved?
what else needs to be relocated etc
or is it fairly simple?

Call Carl, he offers this conversion. Pricey but makes for some good bhp....

ask 20B_Boy. All I know its goning to cost you in a region of 20k at least.
You have modify the subframe, modify transmission tunnel to move the engine back to keep the 50:50 weight distribution, custom exhaust manifold, rewire the electrics,standalone ECU, modify the propshaft. I know of three 20b conversions here and they have at least taken over a year to complete.
So NO in answer to your question its not fairly simple

i am just intrested as i know of someone that might be willing to sell a 20b engine but if it is that much work then i might just see if he will rebuild me one of the 13b\'s he has lying around.  

can anyone tell me is a 13b a 13b in the sence of, for the rx7 did they make a different casing so that it could be mounted etc.  engine mounts etc.  or should a 13b no matter what car it is in be the same?

can anyone post some pics of a stripperd down engine so that i can send them to him to check they are identical.

if its going into an FD make sure its the 13B REW version of the engine, as the 13BT for the FC3S has loads of difference eg port size, rotors. So the 13B REW is the better spec engine and has more HP pontential, unless he has a 13B cosmo engine then you will be very lucky

Ok, the main diffrences in the 13b\'s is the way there mounted, The engine mounts are all diffrent. A 13bt and a 13b-re are the closest  as they are both mounted of the rear plate (just the Engines where made for diffrent Roles so the Port Runners are larger etc for better Torque on the 13b-re) The 13b-Rew from the Fd is center Mounted so it would take a bit of work to put an Fd engine in a Second gen for example.

BUT!!!! If you do your Home work you can make a Hybrid, A mixture of the best bits from the 13b\'s.

Talk to Pip at WGT, hes done a few now, You may have seen his old T2 Race car.

Putting a Triple in a Rx7 is\'nt as hard as it sounds, its been done so many times you can buy the bits like subframes from the US but its like anything the Bits and knolage is there if you have the money to do it.

Don\'t do it.... You\'ll find it a LOT harder than you may think at first and the result will still never be a quicker car point to point than a well sorted 13b would be in the first place!

Comes down to very deep pockets, I have only seen one 20b FD convertion, wasnt that quick on the strip, then again that was two years ago and things have moved on, I know of a \'few\' convertions that are in progress atm, be interesting to see how they perform once compleated, if you are going for it .... best of luck, but be prepared for MASSIVE budget hikes. Not a cheap convertion, just about everything has to be changed.

D1 WTF

well that is cool.  just inquiring.  i dont have any where near the funds necessary at the sound of it.  perhaps i will just wait for my engine to gives up and then go to town on the 13b (funds depending)  although it would be nice to have a spare engine ready to drop in.

Well my one should be done very very soon! :Hammer

you got a date yet Norm,  we\'ve been waitin ages..........  although i do know what has to go into these things

Any idea what sort of power you hope to see?
400 BHP - 650 KG\'s = 616 BHP Per Ton of Rotary Power

That\'s the way to do it! :Thumbsup!

28th May , seen the Turbo, and even got some pics but don\'t know how to put them up on the site. Also have some nice pics of the manifold, and dump valve, they are monsters. Was up there at WGT\'s new site on Tuesday this week, as they were completing the gear box **** loads of work has gone on. Mod on the whole back end of the gear box and selector arm attached to selector box. mods done to bell housing, prop, powerplant, the list goes on and on, all one off fabrications, but the standard of work is spot on ( it\'s gonna be one mother of a car ) All I need to do then is sort the interior out, it\'s ok but not as nice we would all like. it can wait a while. I have a nice covered trialer for it now to live in which Pip is doing up a bit to look like a WGT sponsored race trailer. Then we can go off around the old EU to some of the nice car shows, if I can find out where and when they are. Any help would be good on that one!  :Thumbsup!

28th May, so it will be at RS3 then?
