88 T2 engine with streetport and T70 turbo. running 7psi.
Removed PS and AC.
T2 brakes
T2 Diff
Power windows
Custom front and rear strut braces.

16" summer rim's unknown tyres:?
Walbro fuel pump
FCD
720cc secondary injectors
stiffer bushings in suspension
+ alot of stuff i don't know about or just forgot to mention.

Wow, is that car running on the stock ECU? The fuel there must be very high octane if it did not blow up yet.

[Pettersen]

runs on 91octane.
Also it has 720cc secondarys.

I don't see why it would blow up with the stock ecu just because of porting and a bigger turbo when i'm only running 7psi.

[Max777]

Something about the extra amount of flow compared to the stock turbo at the same pressure level, causing it to go a bit lean. Do you have a Wide Band oxygen sensor to monitor the AFR ratios? I'm curious about how the afr's look under load.

Really, I'm just amazed to see this setup work, didn't know it was possible to run a different turbo w/o a standalone.

[Pettersen]

No wideband yet. will get a haltech one when i buy the standalone.

Nice car. Those tail light rock.

Started on a sub box today,










Finished box, lacks mounting point, and i will also make a coverup panel to make it look like it could have been stock But for now it's ugly as sin...


I'm going to buy a 11" Focal 27v2 at some point(wich will be mounted with the magnet in to the box), but for now i made a spacerplate and mounted a old 12" sub i had layin around.

[Pettersen]

Changed my mind and made new spacers for the old sub so it could be mounted with the magnet in to the box.



painted it black to protect against moisture.




Fits like a glove WHen i buy a new sub it won't build outwards so much.




started on amp and power cap mounting plate

BOOM BOOM baby!

[Pettersen]

Got the jspec ftp lights today

[Pettersen]

Got the downpipe welded




I'm waiting for a new oil feed line, since the old one had seen better days.


Started on updating the ground points in the engine bay, will need to get some shrinkwrap so i can stop using the tape.

[Pettersen]

The RX7 will be staying in theis garage while i finish my bachelor degree, so i have the oppurtunity to do a bit more extensive work than i first had planned

Picture time

The last shots look familiar, the interior is a pain on the FC, but it has to be fixed sometime...

I see you used the opportunity to run power to your subs - good idea, do it right and it probably won't short out and leave you stranded.

Looks good so far.

By the way Max777, the engine is typically the driving factor in air flow rate at a given boost level. With the intake air pressure (boost) kept constant, I can only think of two methods that the air flow rate through the engine could increase by merely changing the turbo:

Method 1: More dense air (cooler charge) due to a more efficient compressor. This actually helps the engine keep from detonating.

Method 2: Lower exhaust backpressure due to a more efficient turbine - decreases the exhaust reversion which lowers the intake air temperature... once again decreasing the tendency to detonate.

The project looks good!

[Pettersen]

Found some more rust, and the worst i've seen on the car so far. Still it's not to bad for a car from 86
And on the bright side, i should become fairly good at welding once i'm done with the rust repair.

Bought a present from me to me
