i see, depends on im replacing the head or block correct? good to know :idea: i asked him before but there wasn't any, the time i was there he had a shipment of R20s and K24s, some Toyota engines and only ONE mitsu 4G92.

nice taste! no promises but i'll pm you to exchange contact before going so we can communicate easier. i think these kinda things needa pray hard wan :adore: as i also need the force to help me find a 93
Lots of work need to be done to fit the 93 internals inside the 92. Hence my advices is to find a proper 93 or 93p and do the swap.

cannot go wrong with that! one more thing, would you trust a workshop or an engineering shop more to perform an engine overhaul? any contacts if so :hmmmm:

im not too sure on that also but aren't there proper engineering workshops that perform all these procedures with proper machinery? still need more exploring, cos i want the best work for a bang of buck :eating:

yet to check out Upwork, RPG yes! visited them two weeks ago and met Sid. i call them the city doctors cause they attend to all cars :rofl:

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:

especially those with families to feed, are prone to kerat a little deeper. true story.
oh. he definitely can fix yours. i'm heading there later to get my car. been close to 4 weeks in the workshop due to wiring problem. not caused by him tho. hopefully he got it fix nicely.

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.
