I know I will get flammed for this but, a shop I went to said they could put a 4g63 engine in my crx for $3,000. Has anybody heard of this?

I think stock they were 220 hp, if they could make it reliable I may concider it.

I did a google and nothing except Bushers rear wheel drive converted crx came up. I searched here and the search is down again.

 

I have seen a 4g63T in a 92 civic, and it was quite fast, but it had prblems with axels and such, the whole wiring... though I am convinced if you can get it working properly it would be a kick *** swap.

 

The shop who suggested the swap specilize in Mitsubishi performance I am sure they could find some stronger axles and deal with the wireing. I have a few questions for you.

Other than axles how reliable was the swap?
How time consuming was the swap?
What other issues was he having?

 

You need a FULLY built tranny if you are going to run decent power, and make sure it is a 6 bolt and not a 7 bolt motor.

Why is that?

Anyway I don't think I will need more than 250-300 at the wheels.

The DSM trannies are notoriously fragile and the 7 bolt motors are known to encounter a phenomenon called "crank walk." The head also uses smaller valves.

If all youwant is 250-300 hp why both with a complex swap like that? Just to be different?

It might be cheaper than a rebuild or another b18c (not to mention to get 250-300 I would need a turbo).

And it would be different.

 

i would suggest the 6 bolt as oppsed to the 7 bolt, but as far as the trans goes...i know the awd trannies are fragile because all 4 wheels are fighting for traction. i have never heard of the fwd ones being weak. one of my friends has a 97 gst with 335 fwhp, and runs it at the track with slicks. never had any problems with it.

edit: you shouldn't worry about getting flamed for wanting to do something out of the norm. this industry progresses because people are constantly doing different things. i personally think it would be a great idea, certainly fast as hell.

 

its not dsm awd trannies that are fragile, its once there is a large amount of power being put thru them. that holds true for any car. my old gsx had 150k on its stock tranny; 10k of that were absolute hell that i put it thru. 5000rpm stutterbox launches @ 18psi for years; that car is still running fine with no grinds, dumps out flat 12's all day. i'd call them fragile once you get into the 350+ awhp range. then maybe a 4 spider would be some form of safety.

That is what I was trying to say. Sorry if I was unclear. The 7 bolt motor is the one with the crank walk problems and the smaller valves.

 

3,000 just doesn't sound right....its too low.

I mean were talking engine itself, new/modified mounts, new electrical system, new hoses, driveline, and last but certainly not the very least LABOR. And if I remember correctly a GST dynoed at around 160HP/190Ft-TQ with the peak torque being at about 3000 RPM's. I could most certainly be wrong though

what im saying though is this will not be awd. correct me if i am wrong. my thinking is that you are taking an engine made for a 2600ish pounds car (sorry if my numbers are wrong, i have been out of the dsm community for some time now), and dropping it into a car that is significantly lighter. it will natually put less stress on the trans due to the fact that its not trying to lug as much around. plus with 250-300 at the front wheels, i don't think he will have to worry about the trans that much. i would say at most, just have the shop take the trans apart, and inspect it. if things need replacing, just use factory replacements. maybe i am wrong, but that is what i would do. hope i helped in one way or another.

peace

 

It can be done... a guy had a 4G63 in his 90 civic at the track and was pulling low 13's, I am not sure on the price though.

the axels he was using were a mixture of Huyndai and Civic axels (the exact ones escape me at this time)

he Custom made everything for the swap, motor mounts and so on, he is also injured his back, all in all it took him 2 months.

other troubles he was having were charge pipes, he kept blowing them, and the speedometer, since the 92+ civic have electronic speedos and the mitsu have mechanical it was a problem, however the CRX is mechanical so this should not effect you.

Thanks to everybody who helped with this, I am still undecided as to what I am going to do. I will definetly talk to the shop and ask what the plan is and if $3,000 is realistic or not.

Other than it being "unique" I just don't think its the best idea....especially for a beginner type project. You would be much better off trying to fit something somewhat practical in there...like an Accord F series (cheap) and a basic turbo...the parts to do it are out there and its proven.
