Default 89 Teg Motor into 91 CRX SI???

My buddy has a 89 tegra that was wrecked. Engine still good though. Will his engine bolt up to my car like a real zc would. I believe his engine is a d16a1. I could probably get both the engine and ecu for like 200 which is like 400 less than a zc and almost the same damn thing. Oh and i know its in good running condition cuz I helped him change the spark plugs/wires and go through the engine. Any one who can help me please do so I want....no...NEED MORE POWER! And this just seems like a low-cost way to go.

I dont think the d16a1 is a bolt in affair unless you have a 1G CRX/3G Civic. Search the archives, there should be tons of info. on this

What about if I swapped the ecu from his 89 teg to my rex. Will it work? and will it make a diff. I heard somewhere that it gives a lil bit more getup

no.. 87-89 teg motors are d16a1 motors but the mounts are all different and it will be all custom.

b18 came in 90+ teg's

Yup, I woud consider this more of a bolt in if you own a First -G- Crx, or Third -G- Civic!

What i need to know is if his ECU will boost the performance of my car with my stock motor. Later Ill probaly do a b16 for 3200 out the door later on. Is 3200 too much? and the ecu thing is for now so NO ZC swaps at the moment

86-87 Tegs were D16A1 and 88-89 Were D16A3's.. The motor would work fairly well but a stock A6 would probably pull on it.

That 89 teg came rated at 118 crank hp for an LS or RS model, 125 if it was the SE model.... Only a ten hp gain. Ain't worth it.
