I'm thinking about buying a 2001 prelude typeSH from a salvage yard. The car is a theft recovery. They took the motor, 5spd trans, and the ecu. I've called several yards around the countryand all tell me the parts have to come from a 2001 typeSH and that this motor, trans, and ecu are spacific to this year only.

If anybody tell me the difference in the motors transmissions and ecus from a TypeSH and a regular VTEC prelude? I would hate to buy this car and have to sit on it for 6 months or so to try and chase down a lift out.

 

The SH block only mates to an SH tranny and suspension pieces because of the ATTS system. The ecu also helps control it so it is needed. Different axles, control arms etc...

 

so could i just buy the regular prelude stuff and replace it with? and replace the axels too?

 

If you replace the entire front suspension, yeah you can switch to base completely...

Is the ATTS computer gone?

 

Actually, the base model tranny will bolt up to the SH block. You just need the base model ECU for it to work. The driverside inner shaft is different cause of the ATTS. The passanger axles can stay the same.

 

Well it has no engine so that's a moot point. He should just get a base engine/tranny and suspension components and save the trouble

 

IMO, the suspension is really not going to matter. All you're working with is a frame. Both the Base and SH have the same exact frame, so theres really nothing different. Motor mounts are in the same place, and all the components are in the same place. Are you planning on having it lowered? Just get new shock and springs then...

 

so what makes a SH a SH? The motor or the transmission? and where in the car could i find the ATTS computer?

 

ttt

 

Type SH:
Painted side/rear skirts
SH rims
interior door lights
Wing
ATTS
5spd
leather wrap shifter

Base model:
Gray side/rear skirts
Base model rims
Wing is an option
Comes auto or 5spd

The atts computer is located right beside the ECU which is under the carpet on the passanger side

 

so the only differance performance wise is going to be in the transmission. the motor from a SH and a regular dohc VTEC prelude are the same?

 

only difference is handling .. everything else is same besides the visual stuff as stated above

 

SH = special handeling and has the following components that differentiate it from the base model:

the front OEM pieces are different [i.e. spring perches are at different heights, lower on the SH, a-arm location is different, and the crossmemeber is also different, as well as the added ~ 2 degrees of castor found on the SH model vs. Base].


Cams
Shift boot and ****
The doors come w/ a little light on the bottom edge
Rear deck doesn't have the space for a third brake light
Spoiler comes stock.
ATTS
Side sills and rear lower sill are color matched to the car on SH's
gauge cluster, as it has the ATTS light
ECU

 

Yeah, same motor, just different trannies.

 

.... mine are black, not grey

 

I meant unpainted.

 

Are the pricing between the type SH and VTEC preludes big? I'm a lil new to Preludes and i was wondering what were the prices for these...Did they make SH's 4th generation? lets say a '97 what are the prices? thanks......

 

the SH stickered at right around $26,500. the base at $23,500ish brand new. and the SH model is only available from 97-01 (5th gen)

alright thanks a lot

 

I saw people saying that the SH engine is no different than the Base engine. That is completely wrong. The blocks are different and a base transmission will NOT bolt up to a SH block.

The SH block is made for the ATTS unit and doesn't utilize an intermediate shaft as the base block does. You might be able to utilize a base intermediate shaft on a SH block but I doubt it. Since the back of the blocks are very different because of the ATTS unit the SH block is designed for.

 

You're completely wrong about the base model tranny bolting up to the SH block. I know it bolts up for a fact cause I did it to my car. After I blew my motor, a friend of mine who owns a salvage yard only had an SH motor without the tranny. I was able to bolt my base tranny onto the SH block, and it worked perfectly. All I changed out was the engine harness(probably didn't need to, but did just in case) and used the base model ECU. The inner shaft on the driverside doesn't fit, but I was able to also have another friend of mine customize it in order for it to work. He made a brace so that it won't slip out. You're RIGHT about the base inner shaft axle not working, but you're WRONG about the base tranny fitting the SH block. There are only 2 things different between the blocks. The way the oil filter sits, and where the inner axles hook up...

 

Type SH are also slower then base.. they put down 10less hp at the wheel because of atts

 

show some dyno sheets proving that claim.

 

Never heard of that. I know they are slower cause they are a little bit heavier, but they are pushing the same HP outta both.
