SR20 in an MSP...

[RevLimitLaunch]

if so ill have to get a diff motor assembly. i want it to be as easy as possible, and converting to obd1 is sh*tty as i'd like to keep obd2

 

[david_shea]

dude that would be badass if you made your MSP a RWD, my buddy on the formula D circuit wanted to do like a rotary in my P5 and go RWD. of course buttloads of money butt damn our cars would look schweet sideways. I grew up with SR20's in japan so I love them, good luck.(cool)

how so? OBDI is much much easier to tune than OBDII why do you think alot of honda guys will convert from OBDII to OBDI or even OBD0. There are less safety measures in OBDI systems so you dont need to worry about the junk you dont need

Agreed.

To be honest with you guys, I'd find a used/abused Lexus IS300 and do an SR20 swap. It shouldn't be that hard, as the JDM version had a 4cyl already and parts could be sourced that way.

Also, I think swapping a 2JZ-GTTE (Supra TT) into an IS300 or GS300 is droolworthy and shouldn't be difficult either. They were all 3.0 inline-6 engines, and my understanding is that the motor mounts are in the same locations.

I know somebody that did a Supra TT swap into an IS, very cool swap.

its something ill have to think about. i know its easier with obd1/obd0 but id like to keep obd2 in a way. either way the wiring seems like its gonna be about as fun as kick to the balls (lick) . luckily, i never realized to look at first, the transmissions are located on the same side. that would've pretty much ended the project or had me go back to the drawing board lol.

if you did infact have OBD1 or OBD0 put in, I wonder what your chances of passing inspection would be?

if you have a vehicle after the starting date of OBII (or if its supposed to be there) isnt it mandatory that the vehicle be equipped with it?

why would the location of the tranny be a problem?
this is something i don't understand....
if you are going to create custom mounts, i don't really think the location of the tranny matters..
the only thing would be the axels, but you will need to custom fab some anyways.

also, since the clutch would be hydraulic, you could just lenghten the line and that's it.

now. you should be careful about the location of the axels, i don't think you want them to be too much at an angle since it would probably damage the tranmission.

another thing, like some others say, what drives you to have a ODBII?
believe me, you won't miss the check engine light.
also, by instaling a standalone, you can do your own wring and probably have a cleaner engine bay without only a few sensors like
CKP, CPS, Coils, Knock, Temp, Oil Pressure.

another thing i see a problem with would be the gauge cluster, nothing would work ovbiously so a TACH and SPEEDO would be a must, unless you can make the old one work.
one more thing, would be the shifter. i don't know what kind of tranny is on that motor but if it is driven by RODS you're pretty much ****** since that would need to be custom made too. if it is driven by cable like on the hondas and mitsubishis then the problem lies on the shifter itself to make it fit.

just some things i thought of.....

have fun

this is something i don't understand....

i think what he was concerned about was that like older hondas and some mitsu setups have the engine "backward" ie the engine is on the left side and trans on the right

and what alejo was getting @, he already has to custom fab new engine mounts, its not going to be much more work to custom fab tranny mounts to allow a transverse engine setup.

understandable but it would be more of a pain in the ass if the setup was backwards

 

[Alejo_NIN]

what difference would that make?

i would understand if you tell me that you are used to seeing the engine going one way.

i would also understand if by having the engine backwards the intake manifold would be infront and exhaust in back(do i make sense?)

also, since you are starting from scratch, still makes no sense to preffer one over the other one. nothing from the existing engine-passengerside tranny-driverside would affect anything at all.
any set should work since in theory everything should be custom made i don't see why chose one over the other one.
in reality either one works unless it is the stock engine, but we already decided on having a completely different engine.
is not like chosing between transversal to horizontal engine locations
or FWD to RWD...

please explain what difference would it make where the transmission is located...

 

[Shadow102]

wiring harness length and routing, ability to use the stock mounting points for engine mounts and building custom mounts of them, shift linkages, and any other interference of the engine and trans.

Either way the SR20 engine does infact sit in the engine bay the correct way so there shouldnt be a huge problem. The only thing i can think of right now that i just brought up above is if the transmission you will be using is a cable or rod shifted setup. If it is rod you may not have to change a whole lot maybey just the length of the rods. A cable shifter could be a little more tricky

 

[RevLimitLaunch]

the trans for the sr20 is cable, and i was concerned. i have places to get it inspected no matter what i do. as for obd1-obd2 i'd rather stick with it but i k now it'll be easier most likely to go obd1 on my part and the easiest way to do it is how it'll be done lol. as for the axles i hear what you mean, the shop ill be going through knows exactly what will be done and im not the only person theyve had to make some custom axles for. and ive found no way in hell the stock cluster will work so ill be getting some gauges, probably autometers and have to make my own gauge cluster from scratch, probably fiberglass or something to do it. that won't be too much of a problem. the shifter is gonna be a pain the ass to get it to work, ill have to take a look at both trannies when i get time to be able to see what ill have to do for it.

 

[JDM-P5]

I know somebody that did a Supra TT swap into an IS, very cool swap.

Very cool...yet very popular.
People have been doing that in the Lexus SC series also.
If I'm not mistaken...the IS powermaker is the detuned na version of the supra powermaker.

 

[Alejo_NIN]

actually, i think having shifter cable gives you more flexibility on the location of both, the tranny and shifter.
just make shure you get the brakets for it and make them work with your new set up

think of it this way, the engine will be centered in the engine bay just like it would on the original car and the shifter would be center in the car just like it would in the original car, now the only problem i see is lenght of the cables, but you'll figure that out, won't you?

If its a cable shifter you may need the entire shifter assembly just because it pivots differently than a rod shifter like the protege has. Also it shouldnt have to go through the floor board straight down instead you may have to run the cables through the firewall.

If I'm not mistaken...the IS powermaker is the detuned na version of the supra powermaker.

It is a 2jz in the IS and supra however the internals and such are different. Stock IS internals arent capable of handling much over a small dose of force induction.

hopefully yes i can have that figured out. i plan on getting p*ssed of alot during it. i'd like to be able to see my buddy's ser right now and compare the two to get a better idea of everything. length of cables shouldn't be all too much of a hassle it can be fixed. but pretty much the whole shifter assembly i guess will have to swapped out to work huh? and im going to do the aem ems for the ecu, no megasquirt, even though i know it'll be far cheaper the aem is just better in my eyes. i wanted to slightly build the top end but because of the aem i might hold off for right now.

Also look into Apex'i i know they make a plug and play unit for the 240 see if the do the same for the FWD version

Yeah...what I/You said.
