Thanks for the link - I contacted them last year & they said they'd never done any development work on the 6 speed box, but 'would if there was enough demand'. I have a gearcutting company in NZ who will make a spool to my details. (I'm in Thailand, no professional machine shops here) On my last...

I am also building a sports car with Subaru engine & transmission. I have an EJ207 & 6spd from an STI spec C. (2006 model) I very quickly abandoned any idea of 4WD and opted for the mid-engine configuration. One major factor for me is minimizing polar mass on the vehicle. The CG of the...

Many thanks guys, this is really helpful feedback. I appreciate your time.

Thanks Pat. You are right, of course! Since you prompted me I checked the geometry of both cars & combined them (on the attachment) - I knew that the STI has 8.5" rims & the Tribeca 8", so did not expect these results! The WRX has 7" rims but on the Subaru websites they quote the same track...

I am building a mid-engine sports car with an EJ20 / 6 speed man. transmission from a 2007 STI donor. The track width of the STI (front) is 58.9" which is not enough for the setupof the rear track in the new build. I see that all subaru models share the same front track dimension except the...

Thanks for the posts, guys. I am fitting a stock Subaru EJ20 STI motor into a new mid-engine car build & need to re-locate the intercooler. I plan to swap that for an EZ36 (turbo rebuild) when I can afford it! and I need to design for that. Perrin's EZ30 was boosted to 22psi max. My question...

Does anyone know what sort of temperature an intercooler rises to during operation? There must be a formula to calculate heat gain when air is pressurised? It would be good to know what sort of temperature to expect, especially in the supply pipe from the turbo. Do fibreglass body panels need...

Thanks for the lead on Bremar. I emailed them & they have responded with the sad news that they do not have a conversion kit for the 6 speed box. Enough requests & apparently they will develop one. I now need to find a company that can make me a locking spool that fits both the inner & outer...

I am also working on a project to build a mid-engine sports car based on the Subaru engine & transmission. I also hunted for months to try to get some technical dimensional info. without success. I have just bought the front end of an 06 Impreza WRX STI (spec C) + 6 spd box.(exported from Japan)...
