Evo 1 with engine freshly rebuilt:

6-bolt block redone
7-bolt head rebuilt (new valve guides and lifters)
Mahle forged pistons (85.5mm)
Scat rods
ARP studs
OEM head gasket
ACL Race bearings
Polished crankshaft

In your opinion, how much boost can it handle before blowing up.

Staying with stock turbo but upgrading injectors, fuel pump, exhaust and computer to run it, how far can a setup like this go in terms of boost? horsepower?

Let's discuss.

Hi guys,

A bit of a head scratcher here.

I went to see a friend who has a 7 bolt 4g63 for sale. The cylinders are overbored slightly. Head gasket is a cosmic metal gasket.

All bolts/studs are ARP. Timing belt was done recently. We checked the timing and it is correct.

The engine is out of the car. Intake and exhaust manifolds are off.

We tried to do a compression test on it.

- Removed all spark plugs

- screw in the compression tester gauge

- Used a battery to power the starter, jump the starter solenoid

The engine turns over but won't give any more than 60-70 psi on all 4.

The owner is 100% certain the engine was running fine when he pulled it out of the car.

What are we doing wrong? I highly doubt and engine with 60-70 psi would "run fine".

We are both baffled.

Any ideas?

Thanks in advance.

I just changed the oil on my evo 1. I put too much in.

Is it a problem or should I just leave it like it is? I am maybe 1.0-1.5 cm above the high mark on the dipstick.

Thanks

Trying to replace the ALT, A/C and PS belts on my 92 Evo GSR.

It looks like it is a very tight fit on the side.

What is the easiest way to do this?

I did a search on the forum and checked all the manuals I have but couldn't find specific info.

Thanks in advance!
