Hey, i've been reading around here alot deciding what im going to buy once i do get my 240. I have talked to a local performance shop that specializes in imports and more specifically 240's and engine swaps.

They said they can custom build an s-13 with the rb20det with a t3/t4 for ~$5500 out the door. Is this a decent price for what i would be getting: rolling chassis, motor, turbo upgrade, and labor?

I dont have the equipment or space to do the swap myself so i must pay someone else to do it for me and i feel much more comfortable knowing it was all done by a professional rather than buying one from a john doe not knowing what kind of work they do.

Also i posted this in the rb section to avoid all the rb bashing, including rb20 bashing by rb25/26 people lol, so PLEASE spare me.

I just want to know if this is a decent price for what im getting? Or if i should shop around some more for a more competative price. Thanks

 

sounds pretty cheap but im not sure, even though rb20's are very cheap i got my clip for 1300, u wont need much else. probably a driveshaft, rear end, and general maitenance. and to do a t3/t4 on this motor is where it will get expensive. since this motor is pretty much maxed out stock meaning, the maf is running 4.9v out of 5v, injectors run at 99%, turbo runs about 14 stock what is also the max it can handle. so u pretty much need to re-do the whole head and fuel system. and then you have to deal with tuning and all that.

 

In terms of the driveshaft and rear end do you mean i would need an upgraded one from stock? Or just in general.

Maybe i wasnt specific enough with my request to the shop and i got confused with their response, but from what i gathered i could show up with just the money and drive it off the lot for 5500-7500 depending on what extra parts and mods i would want on it.

Ill clarify with the shop to make sure though. =)

A little off topic but my eventual goal is ~400 reliable hp to the crank, should i go with a different turbo or will a t3/t4 with the necessary supporting bolt ons and a proper tune suffice.

What kind of cfm does the stock motor accept, from what i understand a bigger turbo with less boost flowing the same cfm as a smaller turbo with more boost is easier on the motor and would make it more reliable. The lag is increased but luckily these motors rev pretty high.

I guess my question is what turbo would be most efficient to reach 400hp without running too much boost where it reduces relaibility?

no you don't need a drive shaft it bolts right up all you need is a McKinney motor sports mount or the crossmember from the clip if you get that.

 

5500 is about the average price for an SR/RB20 swap now a days with a turbo about the same size. So yeah, if you really like the RB20, Id say go for it. But check out if he has like a warranty or anything. Even 30 days coverage is better than nothing.

 

well my swap was relativly cheap. about 2500 total. will be alot cheaper if you do the cross member swap. problem with tuning this motor like i said is if your going to aim for 400. id reccomend an intake manifold and ur going to have to make sure u have an entire fuel system to support it. as well as tuning id suggest a stand alone. safc or avcr will not be usefull to you in going for about 400hp

 

I 2nd his advice.

 

These guys are giving you some good advice. 400 rwhp is attainable, but have you considered maybe an rb25det? for the extra money it will be less of a gap to your power goals and the bump in displacement will help with potential aswell. It is also compatable with the Greddy Intake manifold, and could be more reliable since you would be demanding less from it.. I am in no way knocking the rb20 though, not only are they awesome, I bought one last month !
