NA Build Questions | Blue-/ Redtop questions

[robokill]

Nice list you have here. I would say rebuild a stock bluetop as you will have a fresh new engine which is always better then a used one.

I like the list though I don't see a reason why you would need the adjustable camgears and why on earth you would take cams with 288 degree with only 7.9mm lift.

Go less duration with more lift you stock lifters will handle 9mm lift.

Forged connecting rods are nice but I would rather swap over the lifters in the head as you will stay below 8k RPM. (use the yaris ones)

Now here a something I have heared but cannot prove. It seems waterpumps have trouble above 5k rpm. I cannot prove this but I can recall a 20min run on the track where my engine temperature got hot. (water)

Enough people here have build engines and can tell you there specs. 150 hp in the engine shouldn't be the issue. What you should be carefull off is at which RPM you have it.

as I planning to get an AE86 in the next Months I started thinking about an NA engine rebuild. My target is a 140-150HP build, but I'm a little bit unsure how to go with(I'm not an professional :roll: ).
Take the Bluetop and rebuild them, or getting an Redtop from an AE92 and tune it?

The Spec list what I'm planning:
- Head work
- ITB's
- Standalone ECU
- Toda Racing Adjustable Cam Pulleys
- Toda Racing Timming Belt
- Toda Racing Valve Springs
- Toda Racing Camshafts 288° 7.9mm lift
- Toda Racing 0.8mm Head Gasket
- ACL Bearings
- ARP Rods/ Bolts
- New OEM water/oil pump
- Forged Connection Rods

optional:
- ?

So whats Your opinion about this Setup? I'm open for other thoughts / builds
Btw I'm planning this setup as an reliable engine for Street/ Trackday use (taking the advantage of the german change plate option for two cars)
