After the bad news with my engine being on its last legs I\'ve decided to install a 13b into the 1st gen. It will still be an LPG setup (sorry era) but the 13b is much more rebuildable and has more potential !
Im going to order a reasonable 13b, order a gsl-le sump, reslot my engine mount, install the 12a front plate and 12a dizzy.
The main bits that are worrying me at the moment are designing the intake track. Im looking at common runners going into a plenum. On top will be a throttle body (single 65-80mm dia ??) with the impco 300a on top of the throttle body.
Im not sure if the nikki could be fit to the top. I\'ve seen it on Era\'s bridgy, but im not sure how to do it !
Done some crazy reading today and my noodle hurts.
Im looking to have peak power about 6500rpm so the runners need to be 17.1in long. I don\'t know what diameter it should be though. I don\'t know what volume the plenum needs to be and what size throttle is needed. Im looking probably at a medium street port on the engine.
Pip said that i should be ok with the 12a S3 gearbox, is that right ?
Too many questions for one day !!!!!
Shaun
Shaun,
i would look at ausrotory.com there is loads of info on there about doing the enigne swaps
Mark
I have done :Giggle
Its not the conversion that scares me. Its getting the intake sorted to work with the engine and the gas ! The aussies mainly go turbo with LPG and the setups are quite different.
Shaun
howzit :)
is it the FC 13B 6-port engine your using ?
if so why not keep it fuel injected ? just have to wire computer change to high pressure pump etc not too hard if youve got a bit of time and there are gas conversions already for them :) just a thought :)
also use the 13B 6-port gearbox aswell as there stronger than the series 3 :) but the series 3 are strong boxes :)
later

Does the series 3 mount to the 2nd gen 13b though.
The big worry on the petrol front is that i don\'t have a petrol tank fitted to the car and all the bits for the gas are installed on the car now !
Im not sure if its a 6-port engine yet, did the egi come in both 4 and 6 port ?
Cheers for the info :D

Not sure i have a 13b 4 port in mine, bascily 13b rotors and 12a end plates makes it nice and easy to fit and you keep the 12a outlet with a 13b inlet
Mark
egi motor is 6 port, nice and strong, should be an easy converesion for you, have one in my rx3 with weber ida, standard motor with light fly wheel and freeflowing exhaust, is it all worth it, lpg, fretting about this and that, get a nice old golf gti if you want power and good economy mk2 16v excellent every day car track day family auto barn stormer, {i have an rx7 for fun as well as the 3} they compliment each other but the golf has the edge in terms of practicalities, a mate has lpg\'d his 16v and that goes well, did it him self and drove from gatwick to scotland at over a tonne and returned the equivellent of 60 mpg.
was at rxengineering a couple of years ago and a series 2 with turbo motor turned up on lpg big single turbo and ported motor, i asked John Blanch if it was any good only good for barbeques. This stuff in a rotary??
have fun
I\'ve got rotaries in my blood now :D I have an FD for the fun weekends. The FB even on naff compression is doing 100 miles on less than £10 :D
It was something I was thinking about anyway, but not as soon as this.
The gas is a good mod, even though not may people use it over here. That confuses the hell out of me, the payback can be awesome. I only need to do about 10k miles to pay back the fuel bill difference :D
Been looking on ausrotary but can\'t find a proper howto yet, still digging !
Cheers
Shaun
£10.00 worth of fuel = 20 miles ! HOWEVER it smells like a proper 2 stroker ...........:InLove :cheers
Shaun - the 1990 EGI is being delivered in a few days, it is gonna be broke so all parts available. keep an eye in the 2nd gen section as i\'ll post up some pics when it gets here. Cheers
sounds like me and shaun might have to make a trip down for engine removal/collection :D
oh yes :D Give me an idea on price for the engine please !
Shaun
Have no idea on the price of the engine, also not sure on the condition yet so prob watch this space. How much of the engine will you be after? maybe silly question but just need to know. Cheers
Not completely sure, may want the gearbox as well. Don\'t need the intake or the exhaust or the ecu or the wiring loom. Its going to be converted to carbs !
Shaun
Ok thats fine, sounds like a project on the go....lol
Will keep in touch and as soon as it arrives i\'ll be able to tell you more.
Few pics in the 2nd gen section if you wanna take a gander.
I\'ve ordered my engine off tim in the end. Its a runner thats been rebuilt so hopefully dropping it in within a couple of weeks !
Shaun
what did you go for in the end?
Mark
The most i know about it is it is a 13b egi that was rebuilt 5yrs ago. I only need the bare block and intake side. Should let me get the engine swapped over and running better in a short space of time.
I\'ll do a write up once i start because iformation is sketchy on ausrotary and its all related to the T2 engine.
Shaun
woohoooo pencil me in for engine removal :D
What about the fitting bit :p
Shaun
sounds like your gonna have some fun, plenty of pictures and a good wright up!!:Thumbsup!
Mark
you know me mate - always happy to help ( either removing engines or putting them in )
you will have to let me know when you are "thinking" or starting - the little one is due on the 22 May - so not sure how much time i will have
Stu
Don\'t worry bud. Im off the week before and was looking at doing it then. But there is alot of work to do before fitting the engine that may force me to postpone the installation and do my suspension instead !
Hope mums doing very well and all goes to plan :D
Shaun
im hoping it goes to plan aswell !!
if you need a hand in the evening - just let me know
don\'t you worry, I will :D
Shaun
good man - you have a PM winging its way to you once i write it :D
