So quick intro.
Starting to build Haynes Roadster, and i plan to use B235E recently bought from
https://www.ebay.co.uk/itm/Saab-9-5-2290cc-B235-Eco-Power-Turbo-Engine/133144900911?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 in great condition for 100k miles.....received it today and striped for full rebuild....
With 690 - 720kg car its useless to ask for more than 280 - 320hp.
I dont want to go forged for now, just to have maximum from what i have. I read that B2x4 is more preferable option, but it's hard to find in my country. And if any, they are rarely in good condition.
Trionic 5 will be used, have different sets of bigger injectors, can fit as large downpipe as i want cause im not so much space restricted.....big FMIC as well, balance shafts removal, servo and power steering pump useless too......
Have to admit that i never thought that i will spend so much time reading and searching info about Saab engines, i'm more to italian cars.
But ability go mate engine with BMW gearboxes grab me, easiest tuning without changing hardware......
Still need to ask few questions numbered as follows.
1. Found a man in UK making gearbox adapter plates B2x5 to BMW gb's, but what flywheel, clutch friction and pressure plate can i use - same for the starter motor?
2. Any good use of other Saab camshafts and which?
3. Have almost new GT28RS in my garage, is it good choice instead of TD04 - remap is not a problem, have friend with dyno available?
4. Custom exhaust manifold????....Even if stock is capable enough, i also need as light as possible engine.....and car......any cheap alternatives????
5. Is there any sump mods i can make to avoid oil surge - engine fitted longitudinally and maybe different G forces - can weld alloy, so no problem.
6. Is there any gain in throttle body or intake mod's - had some experience with 5 cyl Fiat Coupe turbo engine(had 2 running with 320 - 350hp with 1 spare) they had bigger TB's????
There will be more question i guess because it's just my first day stripping SAAB engine, but here i start.
