Planning on buying a 1990 GTU but...

i was wondering if its worth it being that it is $2,200 i looked at the car, body is in good condition and so is the inside, but the engine has about 127k miles on it. so is it worth buying it for that amount because i plan to turbo it later, i used to have an 88 FC Vert but my engine blew, it sucked it was a really nice car too .


Thanks

Hold out and wait for a good Turbo II. Swaps are a bitch..Dont even get me started on turbo envy.

ok because i found a 91 turbo II for 3000, but the guy said the ecu is messed up so how much is that to replace and is it hard? and also wouldnt it be easier to put a TII in a GTU? because i guess it's ready for it.

As far as I know its easier to not swap an engine than swap a whole engine into a car. If you put a TII in a GTU you'll need to buy the TII engine, tranny, driveshaft, ECU, and a whole bunch of other goodies that'll total to more than 2-3k.

I believe the market value for TII ecu's go from $100 to $200. It depends on which ECU and S4 or S5. It also depends on market demand, so... At least you could find one of them on the forums here. Just post up or find a post.

The n/a trans will bolt up to the TII engine fine it's just not as strong as the TII trans.

What do you mean by "ready for it"? I wouldn't exactly say that the GTU comes "turbo ready".

Unless you mean that since the engine has lots of miles on it, you might as well put in the TII engine instead of rebuilding the current motor.

Buying and putting in the new ECU for that '91 TurboII would be infinitely easier than turbo'ing the GTU. I mean, you would have to use a Turbo ECU anyways when you do the engine swap.

yeah thats what i meant since the engine is almost gone anyway, and the 91 TII like i said has a messed up ECU and the guy told he broke the key for it and he has to do something weird just to start the car, and the body and inside of the TII is messed up, the GTU body and inside is really good. and i dont mind buying everything to swap a TII into the GTU.

Quick question i also wanted to ask, what exactly is different from the GTU model and the normal model of the 1990 RX-7, what exactly does the GTU have?


THANKS

The short answer though is that the '89-90 GTU was the base car: single piston front brake calipers, solid rear brake discs, open diff, manual roll-up windows, base seats. Don't confuse the S5 GTU with the S4 which was much better equipped.

FYI, You will need to run N/A from the flywheel to the trans in order to use N/A Trans to TII engine.

u asking how dificult it is to change a ecu? u shouldnt even think about attempting a t2 swap. let alone actually do it.

nothing against u but it requires decent mechanical knowledge to do a swap and the questions u ask makes me think u have none.

and 127k on a n/a is nothing a well taken care of gtu is not unheard of reaching 400k.

buy the gtu drive it around awhile save some cash to do the swap right and read up on the fsm and variouse threads on here about swaps and then do it after u have aquired the knowledge

He speaks the truth. When it all comes down to it though, use the knowledge you've gained from us and other websites, asses the information you've gathered, and make a conclusion to what is worth buying. This is your money so what you think is worth it should be what you're going for. If you learn the hard way, at least you learn the lesson very well. I know how to look for a 7 now, but when I first bought my S5 GXL I didn't know what I got myself into and over paid for it. Now I can spot good deals and bad deals...

Kelly blue book (kbb.com) and edmunds.com are much better places to figure out what a car is worth.
