usually your mech/tuner will do the specs/calculation needed and send to engineering shop. then your mech/tuner will install back and tune.

Upwork got a lot of mitsu kaki send there. i got to know of the shop from din6a12. went to his shop to buy gsr brakes and my car that time just swap engine and having problems. he suggest to go to upwork. so i went there, after discussion and checking i decide to do top overhaul. so far until today engine got no problem. they did a good job.
i want to eliminate the mech/tuner factor in spec calculation, only need him for disassembly and reassembly of the whole engine. deal with the engineering shop directly, buy my own spare parts. just an idea, thought it might help save some bucks or complications :hmmmm:

that is a good first hand review from you, will surely put em on my list. much thanks! :shakehands:

like that gonna be more headache unless you know all the correct calculation. better let the mech/tuner do what is best for your engine.

Yeah. I did top overhaul, oversize valves, change piston rings. They also check my conrod bearings and change it coz it was already rough when i got it. And also swap my trailing arm bush. Total was RM1.8k. Other shops that time quoted me RM2k minimum for top overhaul only. :confused:

coming from one who has done and lived through that phase, point taken! key is to find a trusted mechanic and you also have helped me with that. lemme buy you a drink!

reasonable! i was quoted 2.2k for my top set OH and the bill ended at 3k, bear in mind he added NOT decreased my engine's problem. you just confirmed again that i was dumbfounded :hahaha:

he can fix yours, he can fix mine. that's the level of faith i have :biggrin:

Eh? U can use 92 block and swap all the 93 internals in it if u can't find 93 block. 92 pistons slightly higher comp than 93. But the bore is the same. 93 got longer stroke but the the crank can fit into the 92 block. Best is to find 93 block kosong and 93 head kosong and swap. Your dad's friend can sure find 93 dohc set for cheap right?

I'm looking for MOMO 4 spoke gsr steering or Nardi 4 spoke. If can't find, I'd settle for MOMO Corse 3 spoke. It's funny when you're not looking for steerings it just pop up everywhere. When you're looking for one, u cant find any. :sleep:
i bought momo subaru steering wheel. But too big.

How many inches is too big?
standard size. Not sure the size. Currently using aftermarket 350mm. Just nice.
Mod not much on that subaru steering. Clock spring cable connection only.
I still modify the clock spring connector for hub and aftermarket steering.

Where you go wrap this steering? or you DIY?:rolleyes:
These sort of wrap was popular last time. Had to search many shops before I found it. Wrapped myself. Quite easy.

I like thicker steering. The feel is good. Very good grip :top:

Hey, if you do manage to find this wrap, let me know where. Want to keep spare
