i heard there used to be engine kits for the 5mge to make them into 3.0 or even 3.1 i heard these are old old school tho and were done by TRD? am i getting false info or is this true? or is it basically machine work with bigger pistons? heh just wondering

??

re:

Toysport has a 2.9 liter kit and a 3.1 liter kit for our 5M-GEs. Hope you guys have deep wallets, cause the price on these kits will make you bust your left nut. Bang for the buck, go turbo (after several years learning the hard way, this is the way I will be going for my MKII).

Sounds like you are talking about the Kuwahara kit mentioned obliquely in the first link and directly in the second:

Toysport used to have a Kuwahara engine for sale for $5,500 US

 

[KesekiSupra]

yea but cmon! how many people have bragging rights like that for their 5mge's?

If you want 3L just buy a 6M.

the kuwahara kit is a collectors item... if you had a super low milage supra that was going to be garaged, and shown, then id say go for it... for a driver, in all practicality, id say 6m or 7mgte or 1uzfe

The kuwahara complete motor was making really good power. If I had a few g's lying around, I wouldn't mind having one of those motors for exactly what you said, bragging rights.

power

ok.. i takled with toysport.... no more kuwahara kits left...they do not make em any more... they recomended going with a 6m or a 7m for power but if i was set on staying with my 5m... they have forged pistons and they also recommended having them reprogram my ecu to fit the fuel curve of the new set up... they offer the service but $950.00US wow...

 

[dogstar]

i was under the impression that our ecu was not reprogrammable...iirc many people on here have tried, and sent ecus to many places, and none have been able to do it.

im not sure what magic toysport has, but ive heard that they promise many things they cant deliver (illumina shocks anyone?)

for that kind of money, you can start seriously looking at going turbo, and doing it right.

power

i myself am going turbo.. but imagine a kuahara kit with a turbo...im druling at the thought...but i am tring to decide on the fuel system....i think the cheapest and best is to go with an sds system...

 

[KesekiSupra]

looks like its time to create our own kuwahara engines from forged pistons and what not :twisted:

engine kit

if there was enough up front interest maybe this could be done so whats is with the kuhara kit?? to get all that displacement ?? longer crankshaft throws ?? notched block necessary ?? obviously forged pistons higher compression etc etc
sounds like a 6m plus
