What's up, I just got an 89 CRX. I want to put a GSR engine it it. Is that the best thing I can do? I want to add a turbo in the future. I heard the Type r cant handle a turbo. Anyway I was going to get a GSR engine, maybe something out of a 99. and beef it up a bit. I pretty much found everything I need, I still cant find a high performance water pump. :thinking:

 

Whats your budget like?? If you are going all out, with a big budget, I'd get a b20 and beef up the internals, and turbo that.

 

If your going Turbo I would avoid VTEC engines. Get a B18A1 or a B20 like Brtecson said and build that for boost.

 

whats wrong with putting a turbo oo a vtec? do they not work well together?

 

Ok im sort of new to the Honda world, but isnt a B20 from a CRV? If im wrong let me know. Would a B20 fit a 89 CRX? My budget isnt really a problem. Its more finding the parts, and knowning what works with what.

 

Avoid VTEC engines? B20's are good engines to build up for turbo because of low compression, and LOTS of torque, not to avoid VTEC.

 

Yep, b20 is from a crv. It will fit with b-series ef engine mounts from www.hmotorsonline.com [correct me if i'm wrong. The turbo will be shoehorned in there tho. Your turbo setup will depend on what kind of racing you are doing.

For your tranny, I'd recommend a tranny from a non-vtec teg. Stay away from gsr/si/type-r trannys because their gearing is too short, imo. You might want to get an LSD or welded No-SD depending on what kind of driving you're going to do.

 

you have several choices of mounts for a b series engine in an ef chassis
Main 3 Incumbent Mfgrs
HASport
Place Racing
HCP Engineering
(there are also several other newer mfgrs of competing mounts)

 

So are u talkin about like a B20 motor w/ a Gsr head? Which would handle more stress a B20 motor w/ gsr head or a B18? (Assuming the racing ur doing is street:-D - wouldnt a supercharger be better but wouldn't that mean a lil custom work to have it work w/ ur b20 setup?)

 

thanx jaje. HASport has the mounts I was thinking of. hmotorsonline is a great place to buy your engine. I think a b20 is ~$700-800. Compare that to a gsr's ~$3000. but then you have to buy a tranny/lsd, which should be that much.

For stock valvetrains, either one is strong enough. Its the bottom end that you may want to beef up [pistons, rings, rod, crank, etc]. Also, if you opt for a vtec head, go for the b16 head. The intake manifold runners are short and fat, and aren't two staged like gsr's. I think b16 heads are a lil cheaper as well. If you chose to go with vtec, be sure to do it right. There are other engine components recommended by most crvtec heads, like a vtec water pump and a few other goodies. Do a search on crvtec for that, or let somebody else tell you about that cause I dont know much about crvtec. I personally would just get a nice cam/gear/spring combo and a head job[:naughty:].

Also, the roots type sc's that you usually see on hondas are kinda "soft", imo. Theyre fine for spirited driving, but aren't efficient enough for real racing. They have nowhere near the potential of a turbo.
