ok until now i have had a really hard time figuring out what i wanted to do with my 87 Parts car cause i didn't know what i wanted now i have finally gotten my mind maybe up i have already started pulling the engine out of an olf Volvo 740 Turbo Wagon this will be mated to a Supra 5spd and then placed in my 87 GTU shell. this isn't asking how just yet but just a thread to put progress on the project.

her is the basic idea im having here. i have a old Volvo 740 turbo wagon wit the B230FT SOHC turbocharged motor and a automatic tranni i will be purchasing a Supra 5spd tranni which there is a write up on placing in a Volvo 740 with the orrginal volvo motor. http://wwwrsphysse.anu.edu.au/~amh11...a_in_volvo.htm<--supra tranni swap

hopeflly i will eventually do a B234F head swap so i will have a DOHC tubro intercooled motor.

^^^ dude, your screen name is weak.


all and all it sounds like a cool swap. my roommate has a supra and a 740 wagon... those volvos make good power and tq and will run forever... and its not too awful on gas.

what type of engine management are you planning on running?

SouthSideSlider

well i plan on simply using the Volvo ECU mounted somewhere in the bodyt as it thwe interior is no existant and this wont be a dd or pretty in any way shape or form.its not gonna have AC,or P/S . the Mazda RECU will say in the car but not be used for much

ok guys and gals im new her and decided to join after i chose to use a B230FT motor from an old Volvo 740 turbo we have out at my uncles to put in a 1987 Mazda RX-7 SE i bught for $100 with no drivetrain. the plan is to used a Supra W58 5spd tranni and a Turbo 2 reare end in the FC which will be gutted and have all sound deadening removed. this should be alot of fun.

alittle photshoping i did:

DO NOT USE THE W58! The R154 is a much more solid transmission, and while it may cost you a bit more, it will hold more power and the gearing will be more performance-oriented towards the turbo. As you guys probably know, a turbo spooling is only as good as the gearing behind it, so pulling a W58 off of a naturally apirated Supra is probably not the best plan. Instead the R154 came in the twin turbo Soarer and a couple other applications and the gearing is more boost-friendly, I suggest checking the Lexus SC300/Toyota Soarer forums and ebay in order to find one.

im not sure if thewy make a Bellhousing conversion for the R145 if they do that would rule.

The R154 was not only used in the Soarer, but in the MK3 Supras in Japan as well as the 7M-GTE turbo Supra in the US. Soarer trannies go for over $1500 because they are rare, but a MK3 tranny can be had state-side for $300-$400. The only differences between the Japan market MK3 Supra/Soarer R154 and the US 7M R154 is the bellhousing...the Japan market trannies will bolt right up to a 1JZ/2JZ while the US spec tranny is only good for the 7M. The bellhousings are unboltable and you can make a US spec tranny work with a 1JZ/2JZ by swapping the bellhousing and running the 7M clutch & flywheel.

W58 trannies aren't known for their strength, but it doesn't mean they won't take some abuse. I've got a '95 SC300 with the stock W58 and a 1JZ dropped in. It made 264 hp & 276 lb-ft of torque at 9 psi, I ran it that way for a few months and upped the boost to 12 psi. This is my daily driver and I did the swap 2 years & 35K miles ago. The tranny & chassis have over 186K on them, and the tranny is a little noisy but works fine. Food for thought.

The W58 is great for daily driving application, but I assumed this guy was looking for more of a performance application. And again the R154 was just designed for a turbocharged car, which is why I suggest its gear ratios over the W58.

Have you had any direct experience with either the W58 or R154? Cause the gear ratios between the two trannies are similar...your statement is confusing. And who says I only daily drive my car...I can show you the video of Alex Pfiffer drifting it years ago, on the stock W58, at 12 psi...tell me how weak it is again?

SouthSideSlider

well with this motor i wont be pushing more than 450hp at best(most stock internal can handle) i've heard a T5 will fit also but i am most cuious about the E-Auto matic for Supras (a guy on TB made a paddleshifter setup using a E-auto.)

Getting anywhere with the project?

I'd probably just slap the car together with the Volvo slush box and NA rear end until you can afford the conversion bellhousing for the W58 and turbo diff and axles.

If you shift the W58 nicely they are alleged to hold up to about 300hp.
