Axels 88 930 Turbo / 2.8 RSR backdate hotrod


Recommended Posts

Been a while but the project is progressing nicely.

88 930 turbo, backdated to a 2.8 RSR. Easier to backdate something that already has the wider RSR shell!

arches needed some work though. Engine is a Richard Chamberlain built 3.25L Longstroke , GT3 crank and on AT Power ITBs - hooked onto Motec.

Off to dyno and wiring now  - new loom. Hoping for 320+ bhp. 

Gearbox G50, lower gearing for pickup and go. KW 3-way coilovers. 

f**k me has it been expensive but the end product hopefully will be lush. 

964 brakes front, 930 turbo rear. 15 fuchs braids. on michelin TBs.. Enjoy the pics ill add some more.

The expression on that dogs face looks like he's laying a monster, smelly dog egg in protest someone has stolen his turbo from that engine

Car looks great Axel

Car looks great Axel,  

But your dogs realised he never going to be able to fit that engine on his own,  maybe that’s why he’s looking glum.

Pretty happy with the results tbh. its a SC engine, 3.25L Longstroke with a GT3 Crank. JE pistons mahle barrels. Schrick 320/308 Cams. RSR rocker arms. Its on AT Power Throttle bodies, and run by MoTec. 

316 BHP and around 350 NM. Curve could be a bit flatter here and there, but oh well - might have to do with the exhaust/headers/ITB combo.

Mega! great build.

I did a backdate from Supersport to 1974 Iroc and you are right the arches are not exactly the same but no one ever pointed it out!

Apparently they can be reprofiled. I can ask my pal who did his if you want.
